Project description:Papillary muscle rupture is an infrequent and highly morbid mechanical complication of acute myocardial infarction. Surgical repair or replacement is traditionally considered first-line therapy. However, many of these patients present in extremis with prohibitively high surgical risk. Repair of mitral regurgitation with the MitraClip device (Abbot Vascular, Menlo Park, CA, USA) is an established therapy to treat degenerative and functional mitral regurgitation. We present a case of successful repair of severe mitral regurgitation due to papillary muscle rupture in the setting of acute myocardial infarction. A two-clip strategy resulted in mild residual mitral regurgitation with resolution of cardiogenic shock and refractory hypoxemia requiring veno-venous extracorporeal membrane oxygenation. Six-month follow-up echocardiogram identified durable results with mild mitral regurgitation and left ventricular ejection fraction of 63 %. Our case demonstrates that percutaneous mitral valve repair with MitraClip is a well-tolerated procedure that can provide acute and long-term benefit for patients with acute mitral regurgitation due to papillary muscle rupture who are at prohibitively high surgical risk. <Learning Objective: Our case illustrates the role of MitraClip in acute mitral regurgitation due to papillary muscle rupture in cardiogenic shock as an alternative to surgical intervention in extremely high-risk patients.>.

Project description:Many patients affected with mitral valve regurgitation suffer from multiple comorbidities. The MitraClip device provides a safe means of transcatheter valve repair in patients with suitable mitral valve anatomy who are at prohibitive risk for surgery. We describe our early procedural outcomes and present a summary of the current state of MitraClip technology in the United States.We performed a retrospective chart review of initial high-risk or inoperable patients who underwent MitraClip placement at our institution after completion of the EVEREST II study. We examined the primary outcome of 30-day mortality, and secondary outcomes included extent of reduction of mitral regurgitation (MR), New York Heart Association (NYHA) functional class improvement, length of stay, and major complications.A total of 115 high-risk patients (mean Society of Thoracic Surgeons predicted risk of mortality 9.4%±6.1%) underwent the MitraClip procedure at our institution between March 2009 and April 2014. Co-morbidities including coronary artery disease (67.8%), pulmonary disease (39.1%) and previous cardiac surgery (44.3%) were common. The device was placed successfully in all patients with a 30-day mortality of 2.6%. All patients demonstrated 3+ or 4+ MR on preoperative imaging, and 80.7% of patients had trace or 1+ MR at hospital discharge. NYHA class improved substantially, with 79% of patients exhibiting class III or IV symptoms pre-procedure and 81% reporting class I or II symptoms at one month follow-up.The MitraClip procedure provides a safe alternative to surgical or medical management for high-risk patients with MR and suitable valve anatomy. A comprehensive heart team approach is essential, with surgeons providing critical assessment of patient suitability for surgery versus percutaneous therapy as well as performance of the valve procedure.

Project description:ObjectiveThe dissemination of mitral valve repair as the first-line treatment and the introduction of MitraClip for patients who have a prohibitive risk for surgery have changed the landscape of mitral valve intervention. The aim of this study is to provide current and generalizable data regarding the trend of mitral valve interventions and outcomes from 2000 to 2016.MethodsPatients ≥18 years of age who underwent mitral-valve interventions were identified using the National Inpatient Sample database. National estimates were generated by means of discharge weights; comorbid conditions were identified using Elixhauser methods. All trends were analyzed with JoinPoint software.ResultsA total of 656,030 mitral valve interventions (298,102 mitral valve replacement, 349,053 mitral valve repair, and 8875 MitraClip) were assessed. No changes in rate of procedures (per 100,000 people in the United States) were observed over this period (annual percent change, -0.4; 95% confidence limit, -1.1 to 0.3; P = .3). From 2000 to 2010, the number of replacements decreased by 5.6% per year (P < .001), whereas repair increased by 8.4% per year from 2000 to 2006 (P < .001). MitraClip procedures increased by 84.4% annually from 2013 to 2016 (P < .001). The burden of comorbidities increased throughout the study for all groups, with the greatest score for MitraClip recipients. Overall, length of stay has decreased for all interventions, most significantly for MitraClip. In-hospital mortality decreased from 8.5% to 3.7% for all interventions, with MitraClip having the most substantial decrease from 3.6% to 1.5%.ConclusionsOver a 17-year period, mitral-valve interventions were associated with improved outcomes despite being applied to an increasingly sicker population.

Project description:BackgroundAnatomical exclusion criteria for the MitraClip procedure have included rheumatic heart disease (RHD) involving the mitral valve. This was primarily because RHD is typically associated with mitral stenosis (MS).Case summaryWe report the case of an 85-year-old male who had recurrent heart failure admissions from severe rheumatic mitral regurgitation (MR). This was successfully treated with the MitraClip system.DiscussionOur case demonstrated the possibility of rheumatic MR being treated by the MitraClip system in appropriately selected patients. Careful examination of the mechanism of MR to determine suitability for MitraClip must be done as well as exclusion of significant MS.

Project description:ObjectivesAmong patients undergoing transcatheter mitral valve repair with the MitraClip device, a relevant proportion (2-6%) requires open mitral valve surgery within 1 year after unsuccessful clip implantation. The goal of this review is to pool data from different reports to provide a comprehensive overview of mitral valve surgery outcomes after the MitraClip procedure and estimate in-hospital and follow-up mortality.MethodsAll published clinical studies reporting on surgical intervention for a failed MitraClip procedure were evaluated for inclusion in this meta-analysis. The primary study outcome was in-hospital mortality. Secondary outcomes were in-hospital adverse events and follow-up mortality. Pooled estimate rates and 95% confidence intervals (CIs) of study outcomes were calculated using a DerSimionian-Laird binary random-effects model. To assess heterogeneity across studies, we used the Cochrane Q statistic to compute I2 values.ResultsOverall, 20 reports were included, comprising 172 patients. Mean age was 70.5 years (95% CI 67.2-73.7 years). The underlying mitral valve disease was functional mitral regurgitation in 50% and degenerative mitral regurgitation in 49% of cases. The indication for surgery was persistent or recurrent mitral regurgitation (grade >2) in 93% of patients, whereas 6% of patients presented with mitral stenosis. At the time of the operation, 80% of patients presented in New York Heart Association functional class III-IV. Despite favourable intraoperative results, in-hospital mortality was 15%. The rate of periprocedural cerebrovascular accidents was 6%. At a mean follow-up of 12 months, all-cause death was 26.5%. Mitral valve replacement was most commonly required because the possibility of valve repair was jeopardized, likely due to severe valve injury after clip implantation.ConclusionsSurgical intervention after failed transcatheter mitral valve intervention is burdened by high in-hospital and 1-year mortality, which reflects reflecting the high-risk baseline profile of the patients. Mitral valve replacement is usually required due to leaflet injury.

Project description:Mitral valve replacement may be indicated in delayed MitraClip (Abbott) failure. Although it would be best to preserve the chordal apparatus during surgical mitral valve replacement, this has not been reported for delayed MitraClip failure, probably because there is almost always impressive inflammation around the MitraClip, which has likely precluded previous attempts at chordal preservation. A successful surgical chordal preservation mitral valve replacement in delayed MitraClip failure is reported here.

Project description:ABSTRACT 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.

Project description:BackgroundImplantation of the MitraClip is a safe and effective therapy for mitral valve repair in patients ineligible for surgery or at high risk of adverse surgical outcomes. However, only limited information is available concerning sex differences in transcatheter mitral valve repair. We therefore sought to conduct a comprehensive meta-analysis of studies that investigated differences between men and women in outcomes following MitraClip implantation.MethodsThe PubMed and Embase databases were searched until November 2019 for studies reporting outcomes after MitraClip implantation in women versus men. Outcomes included all-cause mortality and major complications at 30 days and one year of follow-up.ResultsSix studies (n = 1,109 women; n = 1,743 men) were analyzed. At 30 days, women had a similar risk of postoperative complications, such as stroke, major bleeding, and pericardium effusion, without differences in all-cause mortality, procedure success, or MitraClip usage. At one year, the all-cause mortality, the reduction of mitral regurgitation, and the risk of rehospitalization for heart failure were also comparable between male and female patients.ConclusionGender disparity was not found in complications or prognosis of patients undergoing MitraClip implantation. This study suggests that gender should not be considered as a critical factor in the selection of patients as candidates for MitraClip implantation of concern during follow-up.
