ABSTRACT

Resumo Fundamentos: Os mecanismos subjacentes pelos quais a doença cardíaca reumática (DCR) levam à disfunção valvar grave não são totalmente compreendidos. Objetivo: O presente estudo avaliou as alterações histopatológicas nas valvas mitrais (VM) buscando uma associação entre o padrão de disfunção valvar predominante e os achados histopatológicos. Métodos: Em 40 pacientes submetidos à troca da VM devido a DCR e em 20 controles submetidos a transplante cardíaco, foram analisados os aspectos histológicos da VM excisada. Dados clínicos e ecocardiográficos também foram coletados. As análises histológicas foram realizadas usando coloração com hematoxilina-eosina. Determinou-se inflamação, fibrose, neoangiogênese, calcificação e metaplasia adiposa. Valores de p<0,05 foram considerados estatisticamente significativos. Resultados: A idade média dos pacientes com DCR foi de 53±13 anos, sendo 36 (90%) do sexo feminino, enquanto a idade média dos controles foi de 50±12 anos, semelhante aos casos, sendo a maioria do sexo masculino (70%). O endocárdio valvar reumático apresentou espessura maior que os controles (1,3±0,5 mm versus 0,90±0,4 mm, p=0,003, respectivamente), e infiltrado inflamatório mais intenso no endocárdio (78% versus 36%; p=0,004), com predominância de células mononucleares. Ocorreu fibrose moderada a acentuada mais frequentemente em válvulas reumáticas do que em válvulas controle (100% vs. 29%; p<0,001). Ocorreu calcificação em 35% das valvas reumáticas, principalmente entre as valvas estenóticas, associada à área valvar mitral (p=0,003). Conclusões: Apesar do intenso grau de fibrose, o processo inflamatório permanece ativo na valva mitral reumática, mesmo em doença tardia com disfunção valvar. A calcificação predominou em valvas estenóticas e em pacientes com disfunção ventricular direita.


Abstract Background: The underlying mechanisms by which rheumatic heart disease (RHD) lead to severe valve dysfunction are not completely understood. Objective: The present study evaluated the histopathological changes in mitral valves (MV) seeking an association between the pattern of predominant valvular dysfunction and histopathological findings. Methods: In 40 patients who underwent MV replacement due to RHD, and in 20 controls that underwent heart transplant, histological aspects of the excised MV were analyzed. Clinical and echocardiographic data were also collected. Histological analyses were performed using hematoxylin-eosin staining. Inflammation, fibrosis, neoangiogenesis, calcification and adipose metaplasia were determined. A p value<0.05 was considered to be statistically significant. Results: The mean age of RHD patients was 53±13 years, 36 (90%) were female, whereas the mean age of controls was 50±12 years, similar to the cases, with the majority of males (70%). The rheumatic valve endocardium presented greater thickness than the controls (1.3±0.5 mm versus 0.90±0.4 mm, p=0.003, respectively), and a more intense inflammatory infiltrate in the endocardium (78% versus 36%; p=0.004), with predominance of mononuclear cells. Moderate to marked fibrosis occurred more frequently in rheumatic valves than in control valves (100% vs. 29%; p<0.001). Calcification occurred in 35% of rheumatic valves, especially among stenotic valves, which was associated with the mitral valve area (p=0.003). Conclusions: Despite intense degree of fibrosis, the inflammatory process remains active in the rheumatic mitral valve, even at late disease with valve dysfunction. Calcification predominated in stenotic valves and in patients with right ventricular dysfunction.

ABSTRACT

SUMMARY BACKGROUND: Percutaneous mitral balloon valvuloplasty and mitral valve replacement have been the treatment options for mitral stenosis for several years, however, studies that compare these two modalities are very rare in the literature. ObjectIve: In this article, we aim to investigate the comparison of clinical results of percutaneous mitral balloon valvuloplasty and mitral valve replacement. Methods: 527 patients with rheumatic mitral stenosis, treated with percutaneous mitral balloon valvuloplasty or mitral valve replacement (276 patients with percutaneous mitral balloon valvuloplasty and 251 patients with mitral valve replacement) from 1991 to 2012 were evaluated. The demographic characteristics, clinical, echocardiographic and catheterization data of patients were evaluated retrospectively. The results of early and late clinical follow-up of patients after percutaneous mitral balloon valvuloplasty and mitral valve replacement were also evaluated. Results: The mean follow-up time of the percutaneous mitral balloon valvuloplasty group was 4.7 years and, for the mitral valve replacement-group, it was 5.45 years. The hospital stay of the percutaneous mitral balloon valvuloplasty group was shorter than that of the mitral valve replacement group (2.02 days vs 10.62 days, p<0.001). The hospital mortality rate of percutaneous mitral balloon valvuloplasty and mitral valve replacement were 0% and 2% respectively (p=0.024). In the percutaneous mitral balloon valvuloplasty group, early postprocedural success rate was 92.1%. The event-free survival of percutaneous mitral balloon valvuloplasty and mitral valve replacement was found to be similar. While reintervention was higher in percutaneous mitral balloon valvuloplasty-group (p<0.001), mortality rate was higher in mitral valve replacement-group (p<0.001). Conclusion: Percutaneous mitral balloon valvuloplasty seems to be more advantageous than mitral valve replacement due to low mortality rates, easy application of the procedure and no need for general anesthesia.

ABSTRACT

La disfunción valvular protésica es cada vez más frecuente debido al envejecimiento de la población portadora de bioprótesis y se presenta como un desafío en el momento de su diagnóstico, valoración y tratamiento. Aplicar un enfoque imagenológico multimodal es fundamental para su manejo. Respecto al tratamiento, surge como nueva alternativa un procedimiento mínimamente invasivo de sustitución valvular percutánea, denominado valve in valve, principalmente en pacientes con riesgo quirúrgico elevado. Presentamos uno de los primeros casos locales de implante percutáneo de prótesis mitral transeptal dentro de una bioprótesis mitral quirúrgica disfuncionante.


Prosthetic valve dysfunction is increasingly common due to the aging of the bioprosthesis-bearing population, and it presents a challenge at the time of diagnosis, evaluation, and treatment. A multimodal imaging approach is essential for its management. In relation to treatment, a minimally invasive percutaneous valve replacement procedure called valve in valve arises as a new alternative, mainly in patients with high surgical risk. We present one of first local cases of percutaneous implantation of a transseptal mitral prosthesis within a dysfunctional surgical mitral bioprosthesis.

ABSTRACT

RESUMEN Un corazón con tres aurículas, que sumaba cinco cámaras en total, fue un hecho que sorprendió a la medicina hace ya más de un siglo. Este raro defecto cardíaco congénito tiene muy baja incidencia, lo cual hace que sea muy poco conocido por las jóvenes generaciones de médicos dedicados a las enfermedades cardiovasculares. El cor triatriatum sinister generalmente se diagnostica en la temprana infancia y es considerado una causa congénita de estenosis mitral. La conducta quirúrgica es de elección para poder liberar el obstáculo al adecuado flujo sanguíneo a través de la aurícula izquierda. Se presenta el caso de un adulto joven con síntomas típicos de estenosis mitral, sin aparentes elementos claves al examen físico y con un ecocardiograma que evidencia esta anomalía, apenas vista y publicada en nuestro medio en pacientes adultos.


ABSTRACT A heart with three atria, totaling five chambers in all, was a fact that surprised medicine more than a century ago. This rare congenital heart defect has a very low incidence, which makes it very little known to the young generations of doctors dedicated to cardiovascular diseases. The cor triatriatum sinister is usually diagnosed in early childhood, and it is considered a congenital cause of mitral stenosis. Surgical approach is the choice to release the obstacle in order to adequate blood flow through the left atrium. We present the case of a young adult with typical symptoms of mitral stenosis, without apparent key elements on the physical examination and that the echocardiogram showed this anomaly, hardly seen and published in our field in adult patients.

ABSTRACT

Abstract A 68-year-old man previously subjected to radiotherapy had a prior aortic valve replacement due de radiation induced calcification of the aortic valve. Presently the patient developed severe calcification of the mitral valve ring leading to critical mitral valve stenosis. A supra annular implantation of an On X Conform valve was successfully achieved. The clinical course was uneventful, and the echocardiographic evaluation demonstrated a normal function of the valve. Different alternatives for the surgical management of this complication are discussed.

ABSTRACT

Abstract Objective: To examine the relationship between the left atrial (LA) thrombus presence and the epicardial adipose tissue (EAT) thickness. Methods: Three hundred and twelve consecutive rheumatic mitral valve stenosis (RMVS) patients with mitral valve area (MVA) < 2 cm2 were included in this cross-sectional study. Patients were divided into two groups, those with and those without LA thrombus. Routine biochemical analysis and electrocardiographic examinations were carried out. EAT was measured using transthoracic echocardiography. Results: LA thrombus was determined in 84 (26.9%) RMVS patients. In echocardiographic examinations, higher mean gradient and LA diameter as well as lower MVA were found in the group with LA thrombus (P<0.001). In this group, higher C-reactive protein (CRP) and EAT values were also determined (P<0.001). There was significant correlation between EAT and MVA, CRP, LA appendage peak flow velocity, LA anteroposterior diameter, and mean gradient (P<0.001). Higher EAT values were identified as independently associated with the presence of LA thrombus (odds ratio 59.5; 95% confidence interval 12.1-290.10; P<0.001). Conclusion: Transthoracic echocardiography, routinely used in patients with RMVS, can measure EAT to determine patients who are under risk for thrombus.

ABSTRACT

Resumen El cor triatriatum es una anomalía congénita rara, que representa el 0,4% de todas las malformaciones cardíacas. En esta malformación la aurícula es separada en dos compartimientos por una membrana fibromuscular, que puede ser enteramente intacta o contener fenestraciones de diámetros variables. La aparición de la sintomatología está en relación con las propiedades obstructivas que mimetizan la estenosis mitral y la presencia de una comunicación interauricular. La ecocardiografía bidimensional y el Doppler color son las modalidades diagnósticas no invasivas de elección para el diagnóstico preciso del cor triatriatum y de su repercusión hemodinámica. Se reporta un caso de cor triatriatum en un paciente adulto mayor, en quien se hizo el diagnóstico tardío y casual de esta malformación.


Abstract Cor triatriatum is a rare congenital anomaly that represents 0.4% of all cardiac malformations. In this malformation the atrium is separated into two compartments by a fibrous-muscular membrane that may be completely intact or contain fenestrations with variable diameters. The appearance of symptoms is associated with obstruction-like properties that mimic mitral stenosis and an atrial septal defect. Two-dimensional cardiac ultrasound and colour Doppler are non-invasive methods of choice for the accurate diagnosis of cor triatriatum and its haemodynamic repercussions. A case of cor triatriatum is reported in an elderly patient, in whom a delayed and casual diagnosis was made of this malformation.

ABSTRACT

RESUMEN Introducción: La valvuloplastia mitral percutánea con balón actualmente es el primer procedimiento terapéutico que se contempla en el mundo desarrollado para los pacientes con estenosis mitral reumática e indicación para ello, y se realiza en el Cardiocentro de Santiago de Cuba desde julio de 2008. Objetivos: Describir los resultados de la valvuloplastia mitral percutánea con balón en los pacientes estudiados. Método: Se realizó un estudio observacional y descriptivo, unicéntrico, que incluyó a 91 pacientes tratados mediante este procedimiento en el Cardiocentro de Santiago de Cuba, desde julio de 2008 hasta junio de 2019. Se evaluaron variables clínico-epidemiológicas, ecocardiográficas y hemodinámicas, así como el resultado inmediato del procedimiento. Resultados: Predominaron los pacientes jóvenes (60,4% entre 15-44 años), del sexo femenino (86,8%), con antecedentes de fiebre reumática (48,4%), en clase funcional III (64,8%) de la NYHA (New York Heart Association) y en ritmo sinusal (86,8%). Se logró un aumento promedio del área valvular de más del doble (0,99 vs. 2,12 cm2) del valor inicial y una reducción de la presión auricular mayor de 50% (25,0 vs.11, 76 mmHg), lo que permitió evaluar de satisfactorio el tratamiento en el 95,6% de los pacientes. Se identificó una asociación significativa (Prueba de Fisher ≤ 0,05) entre la puntuación de Wilkins ≤ 8 y el resultado satisfactorio del procedimiento. Conclusiones: Los resultados de la aplicación de la valvuloplastia mitral percutánea con balón en el centro fueron satisfactorios y congruentes con los referidos nacional e internacionalmente.


ABSTRACT Introduction: Percutaneous balloon mitral valvuloplasty has flourished as a mainstream therapy (mostly in developed countries) for treating patients with medical indication and those suffering from rheumatic mitral stenosis. This procedure is performed at the Cardiocentro in Santiago de Cuba since July 2008. Objectives: To describe the results of percutaneous balloon mitral valvuloplasty in the study participants. Methods: A descriptive, single-centered and observational study including 91 patients treated by this procedure was conducted at the Cardiocentro in Santiago de Cuba from July 2008 to June 2019. Clinical/epidemiological, echocardiographic and hemodynamic variables were assessed, as well as immediate procedure outcomes. Results: Young individuals (60.4% between 15-44 years), female (86.8%), with a history of rheumatic fever (48.4%), NYHA (New York Heart Association) functional class III (64.8%) and sinus rhythm (86.8%) predominated. An average increase in valve area of over double (0.99 vs. 2.12 cm2) the initial value and a reduction in atrial pressure of more than 50% (25 vs. 11.76 mmHg) was achieved; thus evidencing that the treatment was effective in 95.6% of the patients. A significant association (Fisher Test ≤ 0.05) was identified between Wilkins score ≤ 8 and satisfactory outcome of the procedure. Conclusions: The results of percutaneous balloon mitral valvuloplasty in the medical center were successful and consistent with those achieved nationally and internationally.

ABSTRACT

Abstract Background: percutaneous transmitral commissurotomy has become an ideal treatment option for mitral stenosis due to its less adverse events and more favorable outcomes. Patients improve symptomatically after percutaneous transmitral commissurotomy but we have minimal available data about the quality of life after percutaneous transmitral commissurotomy. Objective: to assess the quality of life after percutaneous transmitral commissurotomy through WHOQol scoring covering different aspects of life, to determine its correlation with a net gain in mitral valve area (MVA) and to ascertain its association with gender. Methods: it was a prospective cohort study carried out for a period of 15 months. A total of 100 patients with mitral stenosis who had successful percutaneous transmitral commissurotomy done were enrolled in the study. Among the total included, 4 patients were lost to follow up and data were collected from 96 patients. Quality of life was assessed before the procedure, at 1 month and 3 months follow up after percutaneous transmitral commissurotomy using WHOQol scoring questionnaire. Results: among 96 patients, 64 (67%) were females and 32 (33%) were males. WHOQol scoring improved significantly after percutaneous transmitral commissurotomy from 32.8±8.9 to 54.6±11.2 and 62.8± 9.7, after one month and 3 months respectively. There was a significant association between net gain of MVA and WHOQol scoring with an R value of 0.46 and p value of 0.03. There was no difference in group comparison of all the six domains between male and female patients. Conclusion: successful percutaneous transmitral commissurotomy improves the quality of life in mitral stenosis patients regardless of their gender and has a positive correlation with a net gain in mitral valve area.


Resumen Antecedentes: La comisurotomía mitral percutánea se ha convertido en una opción terapéutica ideal para la estenosis mitral, debido a efectos menos adversos y a resultados más favorables. Los pacientes mejoran sintomáticamente tras la realización de esta técnica, aunque se dispone de escasos datos acerca de la calidad de vida tras su puesta en práctica. Objetivo: Evaluar la calidad de vida tras la comisurotomía mitral percutánea mediante la puntuación WHOQol, que cubre diferentes aspectos de la vida, para determinar su correlación con la ganancia neta del área valvular mitral (AVM), y determinar su asociación con el sexo. Métodos: Estudio prospectivo de cohorte durante un periodo de 15 meses, en el que se incluyeron 100 pacientes con estenosis mitral a quienes se les practicó con éxito comisurotomía mitral percutánea. De entre el total incluido, se perdieron 4 pacientes durante el estudio, por lo que se recolectaron datos de los 96 pacientes restantes. La calidad de vida se evaluó antes del procedimiento, y transcurridos un mes y tres meses de seguimiento, utilizando el cuestionario de puntuación WHOQol. Resultados: De los 96 pacientes, 64 (67%) eran mujeres y 32 (33%) varones. La puntuación WHOQol mejoró considerablemente tras la realización de la comisurotomía mitral percutánea, con valores de 32,8±8,9 a 54,6±11,2 y 62,8± 9,7, transcurridos uno y 3 meses, respectivamente. Se produjo una asociación significativa entre la ganancia neta de AVM y la puntuación WHOQol, con un valor R de 0,46 y un valor p de 0,03. No se produjo diferencia alguna en cuanto a la comparación grupal de los seis dominios entre varones y mujeres. Conclusión: La comisurotomía mitral percutánea exitosa mejora la calidad de vida de los pacientes de estenosis mitral, independientemente del sexo, y tiene una correlación positiva con la ganancia neta del área valvular mitral.

ABSTRACT

Abstract Congenital mitral valve stenosis is a rare and severe disease, usually associated with other heart defects. The appropriate intervention depends on the site and mechanism of valvular obstruction and the aim is to avoid or delay valve replacement since it is associated with significant morbidity and mortality. Early single-stage complete repair is associated with better prognosis. We report the case of a 20-month-old child with a supravalvar mitral ring combined with a ventricular septal defect; pulmonary arterial systolic pressure before the surgery was 79 mmHg. The patient underwent a successful surgical repair with good clinical resolution.

ABSTRACT

Abstract Objective: To compare the in-hospital outcomes of a right-sided anterolateral minithoracotomy with those of median sternotomy in patients who received a mitral valve replacement (MVR) because of rheumatic mitral valve stenosis (RMS). Methods: This is a retrospective analysis of 128 patients (34% male) with RMS between 2011 and 2015. The median age was 53 years (45; 56). The mean ejection fraction was 58.4±6.3%. All the subjects were divided into two groups - Group 1 contained 78 patients who underwent MVR via minithoracotomy (MT-MVR), while Group 2 contained 50 patients who underwent MVR via median sternotomy (S-MVR). Results: In the MT-MVR group, a mechanical prosthesis was implanted in 72% of cases, while it was implanted in 90% of cases in the S-MVR group (P=0.01). The duration of myocardial ischemia was similar (MT-MVR, 77±24 min; S-MVR, 70±18 min) (P=0.09). However, the cardiopulmonary bypass time was lower in the S-MVR group than in the MT-MVR group (99±24 min and 119±34 min, respectively) (P≤0.001). There was no difference in the duration of mechanical ventilation, intensive care unit stay, and hospitalization period. Postoperative blood loss was lower in the MT-MVR group (P≤0.001) than in the S-MVR group. There are no statistically significant differences in postoperative complications (superficial wound infection, stroke, delirium, pericardial tamponade, pleural puncture, acute kidney insufficiency, and implantation of pacemaker). The overall in-hospital mortality was 3.9% (P=0.6) Conclusion: The minimally invasive approach for RMS is feasible and has an excellent cosmetic effect without increasing the risk of surgical complications.

ABSTRACT

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)
