RESUMO
Resumen INTRODUCCIÓN: En Estados Unidos, las cardiopatías periparto se registran en 1 de cada 4000 pacientes. Se consideran idiopáticas y se asocian con enfermedades genéticas, problemas inmunológicos y malformaciones cardiacas, sin que se tenga certeza del origen real de este tipo de enfermedades. La miocardiopatía periparto se asocia con el embarazo y el puerperio; los criterios diagnósticos incluyen: a) insuficiencia cardiaca en las últimas cuatro semanas del embarazo o en los cinco meses siguientes al parto, b) ausencia de causas identificables de insuficiencia cardiaca, c) ausencia de enfermedad cardiaca demostrable antes de las últimas cuatro semanas del embarazo y alteración de la función del ventrículo izquierdo (fracción de eyección del ventrículo izquierdo, menor del 45%). La presentación del caso ayudará a que se tenga conocimiento de este problema. CASO CLINICO: Paciente de 26 años, en curso de las 35.4 semanas de embarazo, con inicio abrupto de signos de cardiopatía congestiva: tos, edema, taquicardia e hipertensión arterial. El embarazo finalizó por cesárea, con traslado inmediato a la unidad de cuidados intensivos. La ecocardiografía reportó una valvulopatía no conocida, insuficiencia ventricular izquierda y disminución de la fracción de eyección del ventrículo izquierdo; con lo anterior se integró el diagnóstico de miocardiopatía periparto. CONCLUSIONES: Las cardiopatías periperiparto son alteraciones excepcionales, con cuadros clínicos debidamente definidos y diagnóstico complejo. Las valvulopatías son el último diagnóstico diferencial de cardiopatía congestiva peripuerperal y se han descrito pocos casos asociados con miocardiopatía periparto.
Abstract BACKGROUND: Peripartum heart disease occurs in 1 out of 4000 cases in the United States; currently, its exact origin is unknown, which is why they are called idiopathic. Genetic diseases, immunological problems and heart malformations have been associated, without being certain about the real origin of these pathologies. Peripartum cardiomyopathy is a rare pathology associated with pregnancy and the puerperium, the diagnosis criteria includes: a) Development of heart failure in the last month of pregnancy or in the 5 months after delivery, b) absence of identifiable causes of heart failure, c) absence of demonstrable heart disease prior to the last month of pregnancy and impaired left ventricular function (FEVI less than 45%). The presentation of the case will help to raise awareness about this problem. CLINICAL CASE: A 26-year-old female patient coursing second gestation in the 35.4 pregnancy week, who debuts abruptly with signs of congestive heart disease such as cough, edema, tachycardia and arterial hypertension. The pregnancy was solved by cesarean section with a subsequent stay in Intensive Care Unit, an unknown valvular disease was identified by echocardiography, as well as left ventricular failure and decreased FEVI. Finally, a definitive diagnosis of peripartum cardiomyopathy was integrated. CONCLUSIONS: Peripartum heart disease is a rare occurrence, with well-defined clinical pictures, but difficult to approach and diagnose. Where valvular heart disease is the last differential diagnosis for peripuerperal congestive heart disease, and few cases associated with peripartum cardiomyopathy have been described.
RESUMO
The patient was an 8-years- and 4-months old girl. At the age of one, she visited a previous doctor with hepatomegaly and liver dysfunction. As a result of the examination, she was diagnosed with geleophysic dysplasia. Other than the heart, she was followed in genetics, ophthalmology, orthopedics, endocrinology, and otolaryngology. At 3 years and 5 months, she was first examined by the cardiology department and was found to have mild mitral regurgitation and aortic valve stenosis, and was followed up once a year. The patient was referred to our hospital at 7 years and 11 months, and the cardiac catheterization performed at 8 years and 2 months showed mild mitral valve regurgitation, but the mean pressure gradient was 16 mmHg and the mitral valve area was 0.60 cm2 (MVAi 0.97 cm2/m2), and mitral valve stenosis was observed. The left atrial pressure was as high as 25 mmHg and the average pulmonary artery pressure was as high as 36 mmHg, and pulmonary hypertension was also observed. Intraoperative findings demonstrated that the mitral valve had a marked thickening of the leaflet, the papillary muscles and chordae were also thickened, and the effective valve opening area was narrowed. The leaflet and subvalvular tissue were resected as much as possible and mechanical valve replacement was performed. Postoperatively, the patient recovered satisfactorily and was discharged on the 16th postoperative day. Pathological findings showed no major disturbance in the layered structure of the papillary muscle or the leaflet itself, but it was highly thickened due to mucous degeneration of the leaflet. We report our experience with the rare case described above.
RESUMO
@#Objective To investigate the therapeutic effect, safety and effectiveness of multiple valvular surgery through right anterolateral intercostal thoracotomy, as well as the mid-term follow-up results and surgeon's learning curve. Methods The clinical data of 154 patients with multiple valvular disease were performed minimally invasive cardiac surgery in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Air Force Medical University, from 2015 to 2019 were retrospectively analyzed. There were 103 males and 51 females, aged 23-68 years. Closed cardiopulmonary bypass was established through femoral artery and femoral vein, and the thoracic cavity was entered through a 6 cm transverse incision in the fourth intercostal space on the right side of sternum. Baseline and perioperative characteristics and postoperative outcomes were reviewed. Results There was no perioperative death. The average cardiopulmonary bypass time was 159.3±39.4 min, and the aortic clamping time was 102.3±20.3 min. One patient underwent thoracotomy during the operation, and two patients underwent second thoracotomy for hemostasis. During the follow-up period of 10-55 months, 1 patient died, 2 patients developed mild perivalvular regurgitation, 6 patients developed moderate tricuspid regurgitation, and no serious cardiovascular events occurred in the rest of the patients. Conclusion Our findings demonstrate that multiple valvular surgery through right anterolateral intercostal thoracotomy is safe, and in an acceptable risk of complication. The early and middle follow-up results are satisfactory. The minimally invasive cardiac surgery can also meet the requirements of cosmetology, and is conducive to the recovery of patients' mental and physical health. This method is worthy of application in medical centers with rich experience in routine cardiac surgery.
RESUMO
Abstract Relapsing polychondritis (RP) is an inflammatory disease that involves cartilaginous structures predominantly in the nose, ears, and respiratory tract. Cardiovascular involvement is not common. Despite this, they are the second cause of death in patients with RP. The structures usually affected by this disease are the heart valves, with regurgitation being the most common valvulopathy. We present the case of a patient without the previous diagnosis of RP who was referred to our institute with heart failure secondary to aortic regurgitation, initially attributed to endocarditis.
Resumen La policondritis recurrente (PR) es una enfermedad inflamatoria que afecta a estructuras cartilaginosas, predominantemente las que se encuentran en nariz, pabellones auriculares y vías respiratorias. Las manifestaciones cardiovasculares son poco comunes; sin embargo, son la segunda causa de mortalidad en pacientes con PR. Unas de las estructuras afectadas casi siempre en la PR son las estructuras valvulares y la valvulopatía más común es la insuficiencia aórtica (IA). A continuación se presenta el caso de una paciente sin diagnóstico previo de PR a quien se refirió a este instituto por insuficiencia cardíaca secundaria a IA, atribuida en un principio a endocarditis.

@#Objective To analyze factors affecting the recovery of postoperative left ventricular function in patients with valvular disease combined with heart failure with reduced ejection fraction [HFrEF, left ventricular ejection fraction (LVEF)<40%]. Methods The clinical data of 98 patients with valvular disease combined with HFrEF who underwent surgeries in our hospital from January 2011 to June 2018 were retrospectively analyzed, including 75 males and 23 females aged 9-78 (55.3±11.9) years. Results A total of 15 patients were dead after the operation, including 4 deaths within 3 months and 11 mid-long-term deaths after the operation. Ninety-one patients were followed up for more than 6 months (10 months to 8.6 years). The postoperative cardiac function (NYHA) of 91 patients was classⅠ-Ⅱ, the LVEF of 18 (19.8%) patients increased more than 10%, that of 47 (51.6%) patients maintained at the preoperative level, and that of 26 (28.6%) patients decreased. Postoperative LVEF was more prone to recover in HFrEF patients with sinus rhythm before operation (P=0.038), valvular disease mainly in aortic valve (P=0.026), obvious reduction of left ventricular end diastolic diameter in early postoperative period (P=0.017), and higher systolic pulmonary artery pressure (SPAP) before operation (P=0.018). The risk factors for postoperative LVEF deterioration included large left atrium before operation (P=0.014), smaller left ventricle end systolic diameter before operation (P=0.003), and fast heart rate after operation (P=0.019). Conclusion Mitral valve prolapse patients with obviously increased left ventricular diameter should receive operation as soon as possible. HFrEF patients with aortic valve disease should receive operation positively. The operation efficacy is satisfactory in the HFrEF patients with high SPAP.
RESUMO
Objective To investigate the correlation between serum asymmetric dimethylarginine (ADMA) and cystatin C (CysC) in degenerative calcific aortic valvular disease and its clinical application value.Methods One hundred and eighty patients with degenerative calcific aortic valvular disease who were treated in Beijing Luhe Hospital Affiliated to Capital Medical University from June 2016 to June 2018 were selected as the study subjects,and another 82 healthy subjects from the same hospital in the same period were selected as the control group.Serum ADMA and CysC levels were detected by enzyme-linked immunosorbent assay and latex-enhanced immunoturbidimetric assay.Risk factors of degenerative calcific aortic valvular disease were analyzed by Logistic regression analysis.Evaluation of the diagnostic efficacy of serum ADMA and CysC for degenerative calcific aortic valvular disease was used by receiver operating characteristic curve.Results There were no significant differences in the general data between the two groups in terms of age,gender,body mass index,drinking history,smoking history,and history of hypertension (P＞ 0.05).The systolic blood pressure(SBP),diastolic blood pressure (DBP),heart rate (HR),total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterin(LDL-C),CysC and ADMA levels of the study group were significantly higher than those of the control group [(131.51 ± 19.09) mmHg (1 mmHg=0.133 kPa) vs.(126.48 ± 16.68) mmHg,(91.11 ± 16.35) mmHg vs.(86.89 ± 10.71) mmHg,(74.39 ± 15.22) beats/min vs.(70.09 ± 13.01)beats/min,(4.51 ± 1.12) mmol/L vs.(4.15 ± 0.92) mmol/L,(1.91 ± 0.63) mmol/L vs.(1.60 ± 0.65) mmol/L,(2.59 ± 1.13) mmol/L vs.(2.27 ± 0.85) mmol/L,(1.01 ± 0.22) mg/L vs.(0.79 ± 0.16) mg/L,(20.17 ± 6.38)ng/L vs.(11.88 ± 4.22) ng/L],and left ventricular ejection fraction (LVEF),high density lipoprotein cholesterin (HDL-C) levels were significantly lower than those of the control group [(56.45 ± 9.21)％vs.(60.87 ± 10.02)％,(1.56 ± 0.63) mmol/L vs.(1.76 ± 0.62) mmol/L],there were significant differences (P ＜ 0.05).Logistic multivariate regression analysis showed that serum CysC and ADMA were independent risk factors for degenerative calcific aortic valvular disease (P ＜ 0.05).Receiver operator characteristic (ROC) curve analysis showed that area under curve (AUC) of serum CysC for degenerative valvular heart disease was 0.785,with a sensitivity of 71.67％,and a specificity of 73.17％.The AUC of serum ADMA for degenerative valvular heart disease was 0.862,with a sensitivity of 71.67％,and a specificity of 87.80％.The AUC of serum CysC combined with ADMA in the diagnosis of degenerative valvular heart disease was 0.910,with a sensitivity of 85.56％,and a specificity of 84.15％,which was significantly higher than the two alone (Z =4.897 and 3.335,P ＜ 0.05).Conclusions Serum ADMA is positively correlated with CysC in patients with degenerative valvular heart disease,and can be used as diagnostic serum markers for degenerative calcific aortic valvular disease.It has clinical reference value for improving the diagnosis of degenerative calcific aortic valvular disease.

RESUMO
La enfermedad valvular cardíaca representa un problema de salud pública a nivel mundial. El objetivo del presente estudio de recolección retrospectiva de datos fue determinar la etiología valvular en pacientes que asisten a la consulta de patología valvular del Centro Cardiovascular Regional ASCARDIO-Barquisimeto en el periodo comprendido entre 2002 y 2015. Se revisaron 1760 historias médicas obteniendo como resultado que la insuficiencia mitral fue la lesión valvular más frecuente (66,13%). Con respecto a patología aórtica, la estenosis aórtica severa predominó en un 69,2% de casos seguido de insuficiencia aórtica leve (37,7%). La etiología degenerativa fue la más frecuente para los casos de estenosis e insuficiencia aórtica (76,4% y 59,5% respectivamente). En cuanto a la lesión valvular mitral, predominaron la estenosis (58,3%) e insuficiencia severa (42,4%) mientras que la etiología de la estenosis e insuficiencia mitral fue predominantemente reumática (89% y 33%, respectivamente). La estenosis tricuspídea fue exclusivamente reumática y la insuficiencia tricuspídea y pulmonar se consideró principalmente funcional. La estenosis pulmonar fue exclusivamente congénita. Este estudio aportará información para evaluar la situación actual de la enfermedad valvular cardíaca en el estado Lara(AU)
Valvular heart disease represents a public health problem worldwide. The goal of this study was to determine the etiology of valvular disease in patients that attend the cardiac valvular pathology consult of the Centro Cardiovascular Regional ASCARDIO-Barquisimeto during the period 2002 to 2015. We reviewed 1760 medical charts and the results show that mitral regurgitation was the most frequent lesion (66.13%). In regards to aortic valvular pathology, severe aortic stenosis predominated in 69.2% of cases followed by mild aortic regurgitation (37.7%). The main cause was degenerative for both aortic stenosis and regurgitation (76.4% and 59.5%, respectively). With respect to mitral valve lesion, stenosis and severe regurgitation was more common (58.3%, and 42.4%, respectively), while the etiology of mitral stenosis and insufficiency was in most cases rheumatic. Tricuspid as well as pulmonary regurgitation was considered mainly functional. Pulmonary stenosis was exclusively congenital. This study provided information to evaluate the current situation of cardiac valvular disease in Lara state(AU)

Introduction - Les cardiopathies valvulaires demeurent fréquentes malgré l'amélioration des conditions sanitaires qui ont permis la réduction de l'incidence du rhumatisme articulaire aigu (RAA). Les indications chirurgicales et interventionnelles se sont élargies et nous opérons aujourd'hui à des stades précoces voire asymptomatiques. Une réintervention chirurgicale valvulaire est nécessaire dans environ 15% des cas au cours de l'évolution d'une valvulopathie opérée. L'objectif de notre étude est de déterminer la fréquence des réinterventions valvulaires et d'identifier les principales indications de ces réinterventions. Méthodes - Il s'agit d'une étude rétrospective descriptive, portant sur 45 patients, admis au service de cardiologie du Centre Hospitalo-Universitaire (CHU) d'Oran, de janvier 2011 à juillet 2013, et présentant une valvulopathie déjà opérée nécessitant une autre réintervention chirurgicale valvulaire. Résultats - La moyenne d'âge est de 41 ans, 73% des patients sont des femmes et 27% des hommes (Sex ratio de 0,37). La plupart de nos patients sont symptomatiques (dyspnée stade II de la NYHA). Les réinterventions intéressent la valve mitrale dans 69% des cas, la valve aortique dans 37% des cas et la valve tricuspide dans 35%. Nous avons constaté l'importance des insuffisances aortiques et tricuspides négligées lors de la première intervention (31% et 62% respectivement). Le délai moyen entre les deux interventions, tout type confondu, est de 21 ans. Conclusion - Les réinterventions cardiaques peuvent survenir au cours de l'évolution d'une valvulopathie. Une bonne évaluation cardiaque initiale des valvulopathies lors d'une chirurgie portant sur la valve mitrale ou aortique est indispensable pour pallier au problème d'une réintervention pour des valvulopathies négligées.
Background - Valvular heart disease still common despite improved health conditions that have reduced the rheumatic fever incidence. Surgical and interventional indications have expanded and today we operate at early stages, sometimes even an asymptomatic stage. Valvular reoperation is required in 15% of cases during the evolution of an operated valve disease. The aim of our study is to determine the frequency of valvular reoperations and identify the main indications of these reinterventions. Methods - This is a retrospective study included 45 patients who were admitted to the cardiology department of University Hospital center of Oran, from January 2011 to July 2013 and who had previously operated valvular disease requiring another surgical valvular reoperation. Results - The mean age is 41 years. 73% of patients are women and 27% are men. 95% of patients are symptomatic (NYHA dyspnea stage II). Reinterventions affected the mitral valve in 69% of cases, the aortic valve in 37% cases and the tricuspid valve in 35%. We reporte the importance of neglected aortic and tricuspid regurgitation during the first intervention (31% and 62% respectively). The average time between the two interventions, all types combined, is 21 years. Conclusion - Cardiac reoperations may occur during the course of valvular heart disease. A good initial cardiac evaluation before surgery on the mitral or aortic valve is essential to overcome the problem of neglected valvular disease reoperation.

Objective:To investigate the expression of fibrillin-1 (FBN-1) in the atrium tissue of the patients with rheumatic heart valve disease complicated with atrial fibrillation(AF), and to explore its relationship with atrial fibrosis in the patients with valvular atrial fibrillation.Methods:Eighty-four consecutive patients with rheumatic heart valve disease underwent cardiac surgery were enrolled in this study.The patients were divided into AF group(n=39) and sinus rhythm group(SR group, n=45).The clinical data of patients were collected before operation.The right atrium tissue (0.3-0.5 mm3) was disserted during operation.The degrees of right atrial fibrosis of the patients in two groups were observed by Masson staining.Western blotting method was used to measure the protein expressions of FBN-1 in atrium tissue of the patients in two groups.Results:There were no significant differences in the gender ratio, age, blood pressure, blood biochemical indicators and other aspects of medical history between two groups(P>0.05);the diameters of left and right atrium of the patients in AF group were significantly larger than those in SR group(P<0.05).The Masson staining results showed that there was obvious fibrosis in AF group, and the collagen volume fraction and collagen level in AF group were significantly higher than those in SR group (P<0.05).The expression level of FBN-1 in right atrium tissue in AF group was obviously higher than that in SR group(P<0.05).The expression level of FBN-1 protein in right atrium tissue of the patients with valvular atrial fibrillation was positively correlated with the collagen level(r=0.544,P=0.021).Conclusion:There is obvious atrium fibrosis in the patients with valvular atrial fibrillation;it is closely related to the up-regulation of the expression of FBN-1 gene.
RESUMO
Objective To analyze the therapeutic effect of emergency surgery in the treatment of severe valvular heart disease and its influence on heart function.Methods 87 cases with severe valvular heart disease were selected,and they were given emergency surgical treatment.Before and after treatment,the cardiac function index[end -diastolic volume (EDV),end-systolic volume (ESV),left ventricular end systolic volume index (LVESVI),left ventricular end-diastolic volume index (LVEDVI),left ventricular ejection fraction (LVEF)],postoperative complications and survival rate were compared.Results After treatment,the EDV [(125.78 ± 31.67) mL],ESV [(71.30 ± 16.58) mL] and LVESVI [(50.39 ± 13.30) mL/m2],LVEDVI [(88.74 ± 13.51) mL/m2],LVEF [(51.48 ± 12.73) ％] were better than those before treatment [(116.48 ± 28.94) mL,(63.26 ± 15.47) mL,(33.27 ± 8.54) mL/m2,(64.47 ± 12.69)mL/m2,(47.53 ± 11.20)％],the differences were statistically significant (t =2.022,2.022,3.307,12.213,2.173,all P ＜ 0.05).The incidence rate of complications was 24.14％ (21/87),included arrhythmia in 4 cases,low cardiac output syndrome in 8 cases,acute renal failure in 9 cases.Postoperative 1 year,2 years,the survival rates were 91.95％ (80/87),85.06％ (74/87),respectively.Conclusion Emergency surgical treatment for severe valvular heart disease can effectively improve cardiac function index,improve the survival rate.
RESUMO
Objective To analyze the clinical characteristics and microbiological pathogens associated with infective endocarditis (IE) in Chinese patients in a university hospital over a 10-year period.Methods We retrospectively evaluated 144 adult IE patients admitted to Peking University First Hospital from 2006 to 2015.Statistical analysis was performed to analyze data on demographics,clinical and laboratory findings,as well as microbiological pathogens.Results The mean age of the 144 patients was 46.6 years.The male to female ratio was 2.3.The most common underlying heart diseases were congenital heart disease (22.9％),followed by degenerative valvular disease (18.8％) and rheumatic heart disease (10.4％).The most common clinical manifestation was fever (91.7％),followed by cardiac murmur (90.3％) and anemia (76.4％).Mitral (40.3％) and aortic valves (39.6％) were most frequently affected.The right-sided IE cases were all found in patients with congenital heart disease.Positive blood culture was documented in 87 IE patients.Streptococcus viridans was the most common pathogen (55.2％,48 episodes),followed by Staphylococcus (24.1％,21 episodes).The prevalence of methicillin-resistant Staphylococcus was 38.1％.Forty-eight (94.1％) of the 51 strains of Streptococcus spp.were susceptible to penicillin.Conclusions Congenital heart disease and degenerative valvular disease have overtaken rheumatic heart disease as the major underlying heart diseases associated with IE.Streptococcus viridans is still the most common pathogen ofIE in China.
RESUMO
Objective To investigate the expression of α-smooth muscle actin (α-SMA)in patients with valvular atrial fibrillation and study the relationship betweenα-SMA and atrial fibrosis in patients with valvular atrial fibrillation (AF).Methods For this study we enrolled 84 consecutive patients with rheumatic heart disease who were to receive cardiac surgery.The patients were divided into AF group (AF,n=39)and sinus rhythm group (SR, n=45).Their clinical data including baseline demographics,routine laboratory test and echocardiographics were collected before surgery.The right atrial tissue (0 .3-0 .5 cm3 )was disserted during the surgery.Right atrial fibrosis was observed by Masson staining.The mRNA expression ofα-SMA in atrial tissue were determined by Real-time quantitative PCR.Western blot was used to measure the protein expression ofα-SMA in atrial tissue.Results The two groups did not significantly differ in sex ratio,age,blood pressure,blood biochemical indicators or other aspects of medical history (P>0.05).However,left and right atrium diameters in AF group were significantly larger than those in SR group (P<0 .05 ).Masson staining suggested that collagen volume fraction and collagen content were significantly higher in AF group than in SR group (P<0 .05 ).The mRNA and protein expressions ofα-SMA in right atrial tissue were obviously higher in AF group than in SR group (coefficients P<0 .05 ).The mRNA and protein expressions ofα-SMA from right atrial tissue in the 84 patients were positively correlated with collagen content (coefficients of 0.587 and 0.607;P=0.029,0.014,respectively).Conclusion There is significant atrial fibrosis in patients with valvular atrial fibrillation,which is closely related to up-regulated expression ofα-SMA gene.
RESUMO
Objective: To explore the occurrence rate of permanent pacemaker implantation (PPI) with relevant risk factors in patients after mechanical aortic valve replacement. Methods: A total of 1986 consecutive patients with mechanical aortic valve replacement were enrolled in this study. According to PPI conduction caused by severe arrhythmia , the patients were divided into 2 groups: PPI group,n=61 including 27 male with the average age of (53.6 ± 9.03) years and Non-PPI group,n=1925. The median follow-up time was (4.47 ± 4.36) years after valve replacement. Results: The patients in PPI group were with the elder age and higher ratio of pre-existing atrial ifbrillation (AF) than those in Non-PPI group,P1 year) was 2.22%. For PPI indications, there were 70.5% patients with high degree A-V block including 30 of AF combining long intervals, 12 of high degree A-V block, 1 of complete left bundle branch block (LBBB) and 14.8% patients with sick sinus syndrome/sinus arrest/ sinus bradycardia. Conclusion: PPI incidence was at a relative low level, the long term occurrence rate was higher than both short term and midterm; elder age, pre-existing AF could be the high risk factors for PPI requirement, and the major PPI indication was high degree AV block in clinical practice.
RESUMO
Estenosis aórtica (EA) es la enfermedad valvular más común referida para tratamiento quirúrgico. La ecocardiografía es el método de referencia para la evaluación de la severidad. La actual Guía Norteamericana define EA severa como un área valvular derivada por ecuación de continuidad (AVA) 1 cm2, área valvular indexada (Avaí) 0,6 cm2 / m2, gradiente medio de (MG) 40mmHg, y velocidad máxima (Vmax)> 4 m / s. La valoración ecocardiográfica de la EA es compleja, ya que depende de unas pocas mediciones críticas que son técnicamente demandantes, sujetas a errores y dependientes de metodologías de adquisición variable a través de las instituciones. Debe buscarse sistematización y estandarización de los enfoques metodológicos para las mediciones fundamentales de la válvula aórtica. Integrar la ecocardiografía con nuevas herramientas, como el score de calcio por CT y la RM tiene el potencial de hacer una plataforma más amplia para individualizar la severidad de la EA.
Aortic stenosis (AS) is the most common valvular disease referred for surgical treatment. Echocardiography is the state-of-the-art method of AS severity evaluation. Current US guidelines deï¬ne severe AS as a continuity equation-derived valve area (AVA) 1 cm2, indexed valve area (AVAi) 0.6 cm2/m2, mean gradient (MG) 40mmHg, and peak velocity (Vmax) 4 m/s. Echocardiographic AS grading is complex since it relies on a few critical measurements that are technically demanding, subject to error and of variable acquisition methodology across institutions. Systematisationandstandardisationofmethodologicapproaches for fundamental echocardiographic aortic valve measurements must be sought. Integration of echocardiography with emerging independent tools such as CT valvular-calcium-load assessment and MRI has the potential of rendering a more comprehensive platform from which to individualise AS severity grading.

Calcification of mitral valve apparatus in rheumatic pathology is not uncommon but isolated papillary muscle calcification and surrounding trabeculation is very rarely seen. Here valve leaflets and annulus are not calcified. This signifies the involvement of other factors in initiation of calcification other than rheumatic scarring. It may be chronic ventriculopathy that leads to trabecular calcification which involves papillary muscle and may later involve annulus. Clinical significance is that in high risk cases balloon mitral valvuotomy can be given a chance rather than replacement of valve as annulus and leaflets are pliable.
RESUMO
We report a rare case of combined valvular disease concomitant with the communication between the coronary and bronchial arteries. A 76-year-old woman was given a diagnosis of chronic heart failure 8 years previously and received medical therapy but recently she had dyspnea. Ultrasound cardiography revealed aortic regurgitation and mitral regurgitation. Cardiac catheterization confirmed the combined valvular disease and also revealed an aberrant coronary artery. Cardiac computed tomography showed coronary to bronchial artery communication, which caused myocardial ischemia. We performed aortic valve replacement with a bioprosthesis, mitral valve repair, and ligation and division of the aberrant coronary artery. Apart from some postoperative bronchial bleeding that ceased spontaneously the postoperative course was uneventful.
RESUMO
An 85 year-old woman underwent mitral valve replacement with Carpentier-Edwards PERIMOUNT (CEP) at the age of 72 because of rheumatic mitral stenosis. Thirteen years after its implantation, prosthetic valve dysfunction developed increasingly severe aortic valve stenosis and she underwent double valve replacement. Prolapse was found in one leaflet of the explanted CEP valve, while neither visible calcification nor tear was detected.
RESUMO
Objective To explore the relationship between resilience and coping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Methods A total of 208 cardiac valvular postoperative patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ).Results The average score of resilience in cardiac valvular postoperative patients with cardiopulmonary bypass was (55.38±10.63)points.The average score of tenacity,strength and optimism were (28.21 ±5.87)points,(18.21 ±4.02)and (8.96± 1.85)points respectively.The average score of coping style of confrontation,avoidance and acceptance-resignation were(18.13±3.38),(16.95±1.75)and (9.24±2.47)points respectively.All the sub-scores of the resilience were positively correlated with confrontation,and all the sub-scores of the resilience were negatively correlated with avoidance and acceptance-resignation.Conclusions There is a certain degree of correlation between resilience and copping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Nurses should enhance resilience of the patients,guide the patients to adopt effective coping styles,to promote disease rehabilitation and improve the quality of life.
RESUMO
<b>Background</b> : The Japanese Society for Dialysis Therapy in 2011 reports that the number of hemodialysis patients has been increasing and that there is an increase in long-term hemodialysis patients and the aging of hemodialysis induction. Therefore, it can be expected that the number of valve surgeries in chronic hemodialysis patients will increase. However, there are many problems between chronic hemodialysis and valve surgery. <b>Objectives</b> : To describe the results of valve surgery in chronic hemodialysis patients at our institution and evaluate the selection of prosthetic valve and associated problems. <b>Methods</b> : Between January 2001 and June 2011, a total of 29 patients on chronic hemodialysis including 3 patients for re-operation, underwent valve replacements. The average age was 67.3±9.3 years and 17 (65%) were men. The average dialysis duration was 7.9±6.4 years. The etiologies of renal failure were 8 for chronic glomerulonephritis (31%), 8 for nephrosclerosis (31%) and 3 for diabetic nephropathy (12%). <b>Results</b> : There were 2 (7.7%) in-hospital deaths, which resulted from ischemia of intestine and multiple organ failure due to heart failure. Twelve (46%) patients died during the follow-up period and the 5-year survival rate after surgery was as poor as another authors have reported previously (30.6%). However, the 5-year survival rate after hemodialysis introduction was 87.1%, which was better than the report of the Japanese Society for Dialysis Therapy in 2011 (60%). Average age was significantly higher in bioprosthetic valves than in mechanical valves (<i>p</i>=0.02). There was no significant difference in survival rate among mechanical and bioprosthetic valves (<i>p</i>=0.75). There was no significant difference in valve-related complication free rate among mechanical (27.5%) and bioprosthetic valves (23.4%) (<i>p</i>=0.9). Three patients with mechanical valves had cerebral hemorrhage, and 1 patient with bioprosthetic valve had structural valve deterioration. <b>Conclusions</b> : Surgical result of valvular disease in hemodialysis patients was as poor as another authors reported previously (5-year survival rate : 30.6%), but survival rate after hemodialysis introduction was not very poor (87.1%). There was no significant difference in survival rate among mechanical and bioprosthetic valves. Bioprosthetic valve has the risk of reoperation due to early structural valve deterioration, but there was no significant difference in valve-related complication free rates. Therefore, we should select prosthetic valve in consideration of individual cases.
