RESUMO

Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to surgical reoperation in failed bioprostheses and rings. Residual mitral regurgitation following TMVR can present as a valve?in?valve paravalvular leak (PVL) and is associated with increased morbidity and mortality. Current therapies for valve?in?valve PVL are limited. We present a case of a symptomatic patient with severe valve?in?valve PVL after TMVR for a previous surgical bioprosthesis leak, who then underwent a second TMVR as a valve?in?valve?in?valve implantation with a 29 mm Edwards? SAPIEN 3 valve via transseptal approach using three?dimensional (3D) echocardiography. This unique case highlights the complexity of this clinical entity and recognizes 3D transesophageal echocardiography as a valuable tool to guide valve?in?valve PVL closures.echocardiography

RESUMO

@#Rheumatic mitral stenosis is one of the most common cardiac valvulopathies in our country, which is relatively rare in European and American countries. Medical therapy is reserved mainly for the treatment of complications, which can not fundamentally change the valve structure. Only surgical treatments can correct these valve lesions, including closed mitral commissurotomy, percutaneous balloon mitral valvuloplasty, mitral valve repair under direct vision and mitral valve replacement. Numerous studies demonstrate that valve repair provides better long-term results, though it occupies a low proportion clinically. This article reviewed domestic and foreign literature concerning surgical treatments for patients with rheumatic mitral stenosis to provide some reference for the peers.

RESUMO

@#Mitral regurgitation is the most common heart valvular disease at present. In the past, mitral regurgitation was mainly treated by surgical mitral valve repair or replacement. However, with the progress of transcatheter interventional techniques and instruments in recent years, transcatheter mitral valve interventional therapy has gradually shown its advantages and benefited patients. The purpose of this article is to review the progress of transcatheter mitral valve intervention in this year, and to provide prospects for the future of transcatheter mitral valve treatment.

RESUMO

Minimally invasive cardiac surgery (MICS: Minimally Invasive Cardiac Surgery) through a minithoracotomy is becoming a standard approach for heart valve surgery. According to JCVSD data for 2018-2019, 42.6% of mitral valve surgeries were performed using the MICS approach. MICS has various advantages over the standard sternotomy approach, such as superior cosmesis, faster recovery and avoidance of sternal complications. However, caution cannot be overemphasized as procedure-related complications are yet to be fully addressed. These complications include chest wall bleeding, unilateral pulmonary edema, vascular injury, and leg ischemia. Some of these complications tend to occur more frequently during the learning curve period. A strict collaboration between surgeons, anesthesiologists, and operating staff is critical for avoid these complications.

RESUMO

The patient was an 89-year-old male who underwent transcatheter edge-to-edge repair to the mitral valve using MitraClip for severe degenerative mitral regurgitation (MR) one year earlier. Although two clips were implanted, grade III/IV MR still remained. As his heart failure progressed, he was referred to us for surgery. The patient also had aortic stenosis. He underwent mitral valve repair and aortic valve replacement. The postoperative course was uneventful. He was transferred to the referring hospital on postoperative day 14. When performing MitraClip for degenerative MR, it is important to consider carefully not only the operative risk for open surgery but also the anatomical adequacy of MitraClip. When MitraClip fails to control MR, early surgical intervention should be considered.

RESUMO

@#Objective    To investigate the effect of concomitant tricuspid valve repair during mitral valve surgery on the early and mid-term prognosis of the tricuspid valve and right heart function in the patients with moderate or less tricuspid regurgitation. Methods    A retrospective study of 461 patients with mitral valve disease requiring cardiac surgery combined with moderate or less tricuspid regurgitation in our hospital from 2011 to 2014 was done. They were 309 males and 152 females with a median age of 53.00 (44.00, 60.00) years. According to whether they received tricuspid valve repair (Kay’s annuloplasty, DeVega’s annuloplasty or annular ring implantation), the patients were divided into a mitral valve surgery only group (a nTAP group, n=289) and a concomitant tricuspid valve repair group (a TAP group, n=172). At the same time, 43 patients whose tricuspid valve annulus diameter was less than 40 mm in the TAP group were analyzed in subgroups. Results    The median follow-up duration was 3.00 years (range from 0.10 to 9.30 years). There was no perioperative death. Three months after surgery, the anteroposterior diameter of the right ventricle in the TAP group was significantly improved compared with that in the nTAP group [–1.00 (–3.00, 1.00) mm vs. 0.00 (–0.20, 2.00) mm, P=0.048]. Three years after surgery, the improvement of right ventricular anteroposterior diameter in the TAP group was still significant compared with the nTAP group [–1.00 (–2.75, 2.00) mm vs. 2.00 (–0.75, 4.00) mm, P=0.014], and the patients in the TAP group were less likely to develop moderate or more tricuspid regurgitation (3.64% vs. 35.64%, P<0.001). Annuloplasty ring implantation was more effective in preventing regurgitation progression (P=0.044). For patients with a tricuspid annulus diameter less than 40 mm, concomitant tricuspid valve repair was still effective in improving the anteroposterior diameter of the right ventricle in the early follow-up (P=0.036). Conclusion     Concomitant tricuspid valve repair for patients with moderate or less tricuspid regurgitation during mitral valve surgery can effectively improve the tricuspid valve and right heart function in the early and mid-term after surgery. Annuloplasty ring implantation is more effective in preventing regurgitation progression. Patients whose tricuspid annulus diameter is less than 40 mm can also benefit from concomitant tricuspid repair.

RESUMO

La endocarditis infecciosa es una patología heterogénea con una alta mortalidad y requiere tratamiento quirúrgico en al menos la mitad de los casos. Cuando asienta en posición mitral, la reparación valvular en lugar de su sustitución, si bien representa un desafío técnico, ha ido ganando terreno en los últimos años. Describimos el caso de un paciente que se presentó con una endocarditis sobre válvula nativa mitral en quien se realizó una plastia valvular exitosa. Revisaremos la evidencia acerca de su beneficio.


Infective endocarditis is a heterogeneous disease with a high mortality and that requires surgical treatment in at least half of cases. When seated in mitral position, valve repair rather than replacement, while technically challenging, has been gaining popularity in recent years. We describe the case of a patient who presented with a mitral valve endocarditis in whom a successful valve repair was performed. Evidence supporting its use will be reviewed.

RESUMO

Objective:To retrospectively evaluate the clinical effect of mitral valve repair for rheumatic mitral stenosis.Methods:We retropectively analyze the clinical datd of 50 rheumatic mitral disease patients undergoing mitral valve repair from January 2016 to March 2019, the clinical outcome was compaired with those of patients undergoing mitral valve replacement. The operation time, cardiopulmonary bypass time, blood loss, ICU time, hospital stay, and postoperative cardiac function were analyzed, and followed up for 2 years to assess mitral regurgitation, cardiac function, and complication rates.Results:The time of cardiopulmonary bypass and ascending aorta occlusion in the valve repair group were longer than those in the valve replacement group ( P<0.05), and the postoperative ventilator assistance time, ICU stay time, and hospital stay were shorter than those in the valve replacement group ( P<0.05). After 2 years of follow-up, no patients died in the two groups. The rehospitalization rate in the valve repair group was lower than that in the replacement group ( P<0.05), and there was no significant difference in the reoperation rate between the groups ( P>0.05); There was 1 case (2%) of moderate mitral valve regurgitation in the mitral valve repair group, no moderate or severe mitral valve stenosis, no paravalvular leakage in the mitral valve replacement group, and no significant difference between the two groups ( P>0.05). The left ventricular end-diastolic diameter and left ventricular ejection fraction in the mitral valve repair group were significantly better than those in the mitral valve replacement group ( P<0.05). Conclusion:Mitral valve repair is effective in treating rheumatic mitral stenosis. It is beneficial to protect heart function, reduce postoperative anticoagulation complications, and does not increase the rate of reoperation. It is a safe, effective and feasible treatment.

RESUMO

@#Patients with bicuspid aortic valve are often complicated with aortic dilatation. If the aortic valve is of good quality, aortic root replacement with aortic valve preservation is feasible. A 35-year-old male patient with bicuspid aortic regurgitation complicated with ascending aortic aneurysm underwent Remodeling+Ring (modified Yacoub) operation. Echocardiography showed that there was no aortic regurgitation on the 3rd day after operation, and the patient was discharged satisfactorily on the 6th day after operation. Remodeling+Ring surgery ensures the physiological movement of the aortic valve, solves the enlarged annulus, avoids the problems caused by valve replacement, and significantly improves the quality of life of patients, which is worth popularizing.

RESUMO

@#Objective    To evaluate the data of preoperative aortic root CT angiography (CTA), compare it with two-dimensional transthoracic echocardiography and investigate the correlation of the two measurements with the actual intraoperative measurement data. Methods    Clinical data of 53 patients with aortic valve diseases who underwent aortic valve repair in our hospital from January 2018 to August 2020 were retrospectively analyzed, including 38 males and 15 females with an average age of 42.9±18.3 years ranging from 10 to 77 years. Preoperative two-dimensional transthoracic echocardiography (TTE) and aortic root CTA measurements were collected, including aortic valve annulus (AVA), aortic sinus (Sinus) and sino-tubular junction (STJ). In comparison with the intraoperative measurements during the aortic valve repair surgery, the consistency analysis was performed. Results    Both the preoperative echocardiography AVA measurements and the CT AVA measurements were positively correlated with the intraoperative AVA measurements (P<0.001). Compared with the echocardiography AVA data [correlation coefficient (ρ)=0.74, mean squared error (MSE)=12.78], the CT AVA data were more accurate and consistent with the intraoperative AVA measurements (ρ=0.95, MSE=2.72). CT AVA data had a higher correlation coefficient with the intraoperative measurements, compared to that of  the echocardiography AVA data (P<0.001). Conclusion    In comparison with two-dimensional transthoracic echocardiography, preoperative morphological evaluation of aortic root CTA is more consistent with the actual intraoperative measurements during aortic valve repair surgery.

RESUMO

@#Objective    To evaluate the impact of different surgical strategies for moderate functional mitral regurgitation (FMR) at the time of aortic valve replacement (AVR) on patients' prognosis. Methods    A total of 118 AVR patients, including 84 males and 34 females, aged 58.1±12.4 years, who were complicated with moderate FMR were retrospectively recruited. Patients were divided into three groups according to the treatment strategy of mitral valve: a group A (no intervention, n=11), a group B (mitral valve repair, n=51) and a group C (mitral valve replacement, n=56). The primary endpoint was the early and mid-term survival of the patients, and the secondary endpoint was the improvement of FMR. Results    The median follow-up time was 29.5 months. Five patients died perioperatively, all of whom were from the group C. Early postoperative FMR improvement rates in the group A and group B were 90.9% and 94.1% (P=0.694). The mid-term mortality in the three groups were 0.0%, 5.9% and 3.9%, respectively (P=0.264), while the incidences of major cardiovascular and cerebrovascular events were 0.0%, 9.8% and 17.7%, respectively (P=0.230). Improvements of FMR in the group A and group B were 100.0% and 94.3% at the mid-term follow-up (P>0.05). Conclusion    For patients receiving AVR with moderate FMR, conservative treatment or concurrent repair of mitral valve may be more reasonable, while mitral valve replacement may increase the incidence of early and mid-term adverse events.

RESUMO

Objective:We performed a meta-analysis examining outcomes of isolated tricuspid valve repair versus replacement.Methods:We searched PubMed, Embase, the Cochrane Library, Web of Science, CNKI, VIP database and WanFang database from the inception to September 30, 2021 for studies reporting outcomes of both isolated tricuspid valve repair and replacement, excluding congenital tricuspid aetiologies. Data were extracted and pooled using random-effects models and Review Manager 5.3 software.Results:A total of 18 articles were included, covering 10 023 patients, totalling 4 749 repairs and 5 274 replacements. Pooled operative mortality rates and odds ratios (95% confidence intervals) for isolated tricuspid repair and replacement surgery were 8.4% vs. 9.9%, OR=0.64(0.44, 0.93). Tricuspid repair was also associated with lower in-hospital acute renal failure 12.4% vs. 15.6%, OR=0.81(0.72, 0.92) and pacemaker implantation 7.9% vs. 26.4%, OR=0.24 (0.21, 0.30). There were no differences in rates of hospital stroke 14.4% vs. 10.3% , OR = 1.41 (0.98, 2.04) and late mortality rates 13.9% vs. 16.1%, OR=0.91(0.49, 1.69). Conclusion:Isolated tricuspid valve repair is associated with significantly reduced in-hospital mortality, renal failure and pacemaker implantation compared with replacement and is therefore recommended where feasible for isolated tricuspid valve disease.

RESUMO

@#Objective  To evaluate the safety and efficacy of transapical mitral valve repair with moderate-to-severe or severe mitral regurgitation (MR) by using LifeClip system. Methods  We retrospectively analyzed the clinical data of 7 symptomatic patients with moderate-to-severe or severe MR who received transapical mitral valve repair by using the LifeClip system in our hospital from July to November 2021. There were 5 males and 2 females with an average age of 76.0±7.5 years. Results  There were 2 patients with degenerative MR and 5 patients with functional MR. All of the procedures were successful and 6 patients received 1 LifeClip while the other one patient received 2. The operation time was 135.7±46.9 min, the mechanical ventilation time was 12 (3, 14) h, and the hospital stay time was 18.1±4.1 d. No serious complications or death occurred during the perioperative or follow-up period. MR reduction by ≥ grades was achieved in all the patients at the one-month follow-up. The classification of cardiac function was improved in varying degrees. Conclusion  Transapical mitral valve repair using the LifeClip system shows good safety and efficacy for severe MR patients, and MR degree is significantly improved at early follow-up. However, the benefit of LifeClip should be validated in a larger sample size of Chinese population and through long-term follow-up.

RESUMO

Papillary muscle rupture, a complication of acute myocardial infarction, causes acute mitral valve regurgitation. However, to date, only a few articles have reported PMR associated with coronary spasm. In this article, we report the case of a 64-year-old woman who suffered posteromedial papillary muscle rupture caused by coronary spasm or Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA), and was successfully treated with mitral valve repair.

RESUMO

Resumen: Objetivo: Describir las características clínicas, resultados operatorios inmediatos y a 5 años de la cirugía de reparación valvular mitral. Material y métodos: Estudio retrospectivo de la cohorte de pacientes operados de reparación valvular por insuficiencia mitral (IM) en el Hospital Guillermo Grant Benavente desde el 2009 hasta marzo 2020 (N=206). Se comparan los pacientes con IM primaria y secundaria en sus características clínicas, ecocardiográficas, técnicas quirúrgicas empleadas, cirugías asociadas, morbimortalidad operatoria, sobrevida y reintervenciones hasta el 30 de mayo de 2020. Resultados: 124(60,2%) hombres. Edad media 62,6±10,5 años. La IM fue primaria en 134 y secundaria en 72. En comparación con los pacientes portadores de IM primaria, aquellos con IM secundaria tuvieron más enfermedad coronaria (69,4% versus 11,9%; p<0,001) y mayor riesgo operatorio (EuroSCORE logístico 7,7±6,7 versus 5,2±7,3; EuroSCORE II 3,4±4,8 versus 2,4±4,7; p<0,001). El mecanismo más frecuente de IM primaria fue tipo II (65,7%) y en las secundarias fue el tipo III (48,6%) seguido del tipo I (30,6%). Las IM primarias se corrigieron principalmente con procedimientos para disminuir el prolapso (76,1%). En las secundarias la técnica más utilizada fue el implante de un anillo exclusivo (76,4%). Hubo 116 cirugías asociadas y 10 (4,9%) conversiones a reemplazo valvular. Hubo 57 complicaciones operatorias y fallecieron 12 (5,8%) pacientes, 5 (3,7%) con IM primaria y 7(9,7%) con IM secundaria. La sobrevivencia global a 5 años fue 83,5% (90% en las primarias y 78% en las secundarias) y hubo 6 reintervenciones. Conclusiones: La cirugía de reparación valvular, tanto en pacientes con IM primaria como secundaria, tuvo una baja mortalidad operatoria y excelentes resultados a 5 años.


Abstract: Aim: To describe the clinical characteristics, operative and long term results of surgical mitral valve repair. Material and methods: Retrospective study of the cohort of patients undergoing valve repair due to mitral regurgitation (MR) at the Guillermo Grant Benavente Hospital from 2009 to March 2020 (N = 206). Patients with primary and secondary MR were compared on clinical and echocardiographic characteristics, surgical techniques, associated surgeries, operative morbidity and mortality, survival and reinterventions up to May 30, 2020. Results: 124 (60.2%) were men. The average age was 62.6±10.5 years. Type of MR was primary in 134 and secondary in 72. Compared to patients with primary MR, those with secondary MR had more coronary artery disease (69.4% versus 11.9%; p <0.001) and greater operative risk (logistic EuroSCORE 7.7±6, 7 versus 5.2±7.3; EuroSCORE II 3.4±4.8 versus 2,4±4.7; p<0.001). The most frequent mechanism of MR was type II in primary (65.7%) and type III (48.6%) followed by type I (30.6%) in secondary MR. Primary MR was corrected mainly with procedures to decrease prolapse (76.1%). In secondary MR the main technique used was the implantation of an exclusive ring (76.4%). There were 116 associated surgeries and 10(4.9%) conversions to valve replacement. There were 57 operative complications and 12(5.8%) patients died, 5 (3.7%) with primary MR and 7 (9.7%) with secondary MR. Overall survival at 5 years was 83.5% (90% in primary MR and 78% in secondary MR) and there were 3 reoperations. Conclusions: Valve repair surgery in both primary and secondary MR patients was associated to a low operative mortality and excellent results at 5 year post surgery.

RESUMO

Objective:To evaluate the mid-term outcomes of patients with rheumatic heart disease who underwent aortic valve repair surgery in a prospective cohort.Methods:From January 2016 to December 2020, a total of 54 patients with rheumatic heart disease underwent aortic valve repair surgery in Beijing Anzhen Hospital, with an average age of (50.61±13.29) years, including 29 females (53.7%). There were 31 patients (57.4%) had pure aortic insufficiency, 2 patients (3.7%) had pure aortic stenosis and 21 patients (38.9%) had mixed lesion. During the same period, 43 patients (80.0%) underwent mitral valve surgery, 36 patients (66.7%) underwent tricuspid valve surgery, and 20 patients (37.0%) underwent atrial fibrillation radiofrequency ablation.The follow-up period was from 1 month to 61 months (median follow-up was 25 months). Paired rank-sum test was used to compare the differences in continuous variables among subjects, and Kaplan- Meier method was used to analyze the clinical outcomes during the follow-up period. Results:Proportion of moderate and severe aortic regurgitation Preoperatively was higher than that of discharge data, aortic valve orifice maximum velocity and left ventricular end-diastolic diameter were significantly lower than discharge data (all P<0.05). The 5-year survival rate was (96.1±2.7)% (2 patients died). The 5-year freedom from reoperation after aortic valve repair was (89.5±4.5)%(5 patients underwent redo surgery). The 5-year freedom from valvular-related complications was (91.3±4.2)%(3 patients suffered from complications). Conclusion:Aortic valve repair surgery for rheumatic aortic valve disease is feasible and has excellent early and mid-term results, it can be a reliable treatment option.

RESUMO

@#Objective    To evaluate the short and mid-term outcomes of valve repair in patients with insufficient bicuspid aortic valves (BAV). Methods    The clinical data of 27 consecutive patients with insufficient BAV undergoing valve repair in Shanghai Chest Hospital from September 2016 to January 2020 were retrospectively reviewed. There were 24 males and 3 females with a mean age of 38.5±14.6 years (range: 20-68 years). BAV of all patients was type 1 in Seviers' classification. There were 23 patients with left-right fusion and 4 patients with right-noncoronary fusion. There was aortic regurgitation in the patients measured by the echocardiogram, including moderate regurgitation in 3 patients, moderate-severe in 18 patients, and severe in 6 patients. The diameter of aortic annular base was 27.9±3.4 mm, and the largest diameter of aortic sinus was 39.9±7.6 mm. Left ventricular end diastolic diameter was 62.7±6.5 mm, and the volume was 197.9±53.6 mL. Results    All 27 patients completed the follow-up, and the mean time was 24.2±12.5 months (range: 12-51 months). No patient died or required aortic valve-related reoperation during the follow-up. The cardiac function of the patients significantly improved postoperatively (P<0.05). By echocardiography, 11 patients had no aortic regurgitation, 13 had mild aortic regurgitation, and 3 had moderate aortic regurgitation, and no patient had severe aortic regurgitation. Postoperative left ventricular end diastolic diameter and volume decreased, compared to preoperative ones (P<0.05). Conclusion    In patients with insufficient BAV, valve repair is safe and effective, and has excellent short and mid-term outcomes.

RESUMO

@#Objective    To investigate the prognosis and risk factors of mild to moderate or moderate atrioventricular valve regurgitation (AVVR) after Fontan operation. Methods    A total of 34 patients with mild to moderate or moderate AVVR who accepted Fontan operation and atrioventricular valve (AVV) repair between 2004 and 2018 in our center were selected as an AVV repair group. The patients in the same period were matched as a control group by the ratio of 1 : 1-2. Finally 99 patients were included into this study, including 64 males and 35 females, with an average age of 63.4±36.3 months and weight of 17.3±6.7 kg. Grades of AVVR decreased more than 1 was defined as significant improvement. Endpoints of the study were death, Fontan takedown, AVV replacement. Risk factors including Fontan procedures, AVV repair procedures, cardiac anatomy were analyzed. Results    Patients were followed up for 1.5 (0.3-4.0) years. Overall mortality was 15.2%. Most (82.4%) of AVV repair group accepted single AVV repair procedure while partial annuloplasty was the most common (52.9%). With the extension of follow-up, the degree of AVVR in the whole group showed a gradually increasing trend (r=0.352, P=0.000). Mild to moderate AVVR improved spontaneously after Fontan operation, while moderate AVVR did not. AVV repair could improve the degree of AVVR after moderate regurgitation, without increasing the surgical mortality, and regurgitation significantly decreased in 8.8% patients. AVV repair was not effective for mild to moderate AVVR and would increase surgical mortality. Conclusion    AVV function shows a gradual downward trend after Fontan operation. AVV repair is effective for moderate AVVR, does not increase mortality, but the degree of improvement is limited. AVV repair is not effective for mild to moderate AVVR and increases surgical mortality.

RESUMO

@#Objective    To analyze the Ebstein anomaly's reoperative strategy and mid- to long-term results. Methods    We retrospectively reviewed the clinical data of 23 patients who diagnosed with Ebstein anomaly and underwent reoperation for tricuspid valve insufficiency between July 2002 and July 2017 in Fuwai Hospital. There were 9 (39.1%) males and 14 (60.9%) females, with a median age of 28.0 (19.0, 45.0) years. Results    Among the 23 patients, 8 (34.8%) underwent tricuspid valvuloplasty and 15 (65.2%) underwent tricuspid valve replacement. The rate of valvuloplasty was 16.7% before 2012, and 54.5% after 2012 (P=0.089) as Cone reconstruction procedure was used. In the valvuloplasty cohort, 3 (37.5%) patients were treated with Danielson or Carpentier technique, and 5 (62.5%) patients were treated with Cone reconstruction procedure. There was no operation-related death. Early complications occurred in 3 (37.5%) patients. The median follow-up was 6.9 years (range, 3.0-15.1 years), and no adverse cardiac events occurred. In the patients with valve replacement, 7 (46.7%) received mechanical prosthesis and 8 (53.3%) received bio-prosthesis. There was no operation-related death. And early complications were observed in 3 (20.0%) patients. The median follow-up was 6.5 years (range, 2.5-15.3 years). One (6.3%) patient died and 4 (26.7%) had long-term complications during the follow-up period. Conclusion    The mid- to long-term outcomes are convincing in patients who undergo the second operation due to recurrent tricuspid regurgitation of Ebstein anomaly. A low incidence of reoperation is observed. Cone reconstruction procedure provides possibilities of second tricuspid valvuloplasty, and this technique can reduce the rate of tricuspid valve replacement in the second operation. Tricuspid valve replacement is still an alternative method for the treatment of recurrent tricuspid regurgitation in patients with Ebstein anomaly. The bioprosthetic prosthesis may be a better choice than mechanical prosthesis.
