Project description:To analyse the impact of postprocedural mitral regurgitation (MR), in an interaction with aortic regurgitation (AR), on mortality following transcatheter aortic valve implantation (TAVI).To assess the interaction between MR and AR, we compared the survival rate of patients (i) without both significant MR and AR versus (ii) those with either significant MR or significant AR versus (iii) with significant MR and AR, all postprocedure. 381 participants of the Polish Transcatheter Aortic Valve Implantation Registry (166 males (43.6%) and 215 females (56.4%), age 78.8±7.4 years) were analysed. Follow-up was 94.1±96.5 days.In-hospital and midterm mortality were 6.6% and 10.2%, respectively. Significant MR and AR were present in 16% and 8.1% patients, including 3.1% patients with both significant MR and AR. Patients with significant versus insignificant AR differed with respect to mortality (log rank p=0.009). This difference was not apparent in a subgroup of patients without significant MR (log rank p=0.80). In a subgroup of patients without significant AR, there were no significant differences in mortality between individuals with versus without significant MR (log rank p=0.44). Significant MR and AR had a significant impact on mortality only when associated with each other (log rank p<0.0001). At multivariate Cox regression modelling concomitant significant MR and AR were independently associated with mortality (OR 3.2, 95% CI 1.54 to 5.71, p=0.002).Significant MR or AR postprocedure, when isolated, had no impact on survival. Combined MR and AR had a significant impact on a patient's prognosis.

Project description:BackgroundAortic regurgitation (AR) is common and detrimental in patients with left ventricular assist devices (LVADs). Off-label use of transcatheter aortic valve replacement (TAVR) has emerged as a potential treatment option. Further data are required regarding the feasibility and outcomes of TAVR to treat AR in LVAD recipients.MethodsA retrospective review of all patients with LVADs who underwent TAVR for the treatment of AR at a single center was performed. All echocardiograms were independently reviewed to ensure accuracy.ResultsEleven patients with continuous-flow LVADs underwent TAVR for AR. All patients had moderate or severe AR with New York Heart Association (NYHA) class III and IV symptoms. Implantation of more than 1 valve was required in 4 (36.3%) patients; 1 patient died during the procedure because of valve migration into the left ventricle and 1 patient died in-hospital after TAVR. Of 9 (81.8%) patients discharged alive, 8 (72.7%) were alive at 12 months and all survivors had improvement in AR severity, natriuretic peptide levels, left ventricle end-diastolic diameter, and NYHA class. Five (62.5%) survivors had a large improvement (>20 points) in the Kansas City Cardiomyopathy Questionnaire score at 1 year. One survivor experienced heart failure, requiring hospitalization, within 1 year.ConclusionsIn this single-center series, TAVR for the treatment of AR in patients with LVADs is technically challenging but feasible in select patients and may produce durable improvements in AR severity, functional status, and quality of life.

Project description:Patients undergoing transcatheter aortic valve replacement (TAVR) might have an associated significant MR that can potentially lead to left ventricular (LV) failure after procedure. Considering the specific alterations in the mitral valve in TAVR scenario and the widespread use of TAVR in recent years, it appears important to know and understand the anatomical, functional and clinical implications to develop adequate strategies for the future. Patients with severe mitral regurgitation (MR) have been generally excluded from randomized clinical trials, making poor the impact that associated MR can have on clinical outcomes after TAVR. Several factors must be considered whose presence influences the severity of MR. For example, the elevated prevalence of coronary disease with consequent ischemic MR may account for LV dilation observed at the end stage of aortic stenosis. Evidence randomized studies and registries suggests that the rate of concomitant moderate-to-severe MR in patients undergoing TAVR oscillates between 2% and 33%, and patients with moderate to severe MR may have hemodynamic frailty with clinical deterioration during mechanical intervention. Short- and long-term outcomes, including cardiac mortality, appear to be influenced by the existence of preoperative moderate-to-severe MR or by the postprocedural worsening of mild MR, generally due to adverse LV remodeling. The incidence and the prognostic effect of concomitant MR in patients undergoing TAVR requires specific attention as might trigger adjunctive strategy treatment which should be carefully evaluated in clinical trials.KeywordsMitral regurgitation (MR); mitral valve; transcatheter aortic valve; transcatheter aortic valve replacement (TAVR).

Project description:This review outlines the first trial experience with transcatheter therapy for mitral regurgitation (MR), developed from the EVEREST II MitraClip trial in a trial population comprised predominantly of patients with degenerative mitral regurgitation (DMR). Subsequent experience with MitraClip and several other devices has been mostly in functional MR patients. At the same time, there has been ongoing experience with MitraClip in DMR, and a variety of other devices have been developed for catheter-based treatment of MR. Annuloplasty devices have been indicated for DMR, and the potential for transcatheter annuloplasty to be used, in conjunction with other catheter techniques, such as chordal replacement, as it is in standard mitral repair, is developing. Transcatheter mitral valve replacement will clearly have some role for MR of both functional and degenerative etiologies, when repair is not feasible or fails. This review will discuss the evidence base and future development of these mitral repair and replacement approaches for DMR.

Project description:AimsAlthough surgical aortic valve replacement (SAVR) is currently the recommended intervention for patients with native AR without aortic stenosis, a significant proportion of Asian patients undergo transcatheter aortic valve replacement (TAVR), which has not been studied fully for safety and outcomes. This systematic review aims to examine the characteristics and outcomes of Asian patients with pure native aortic regurgitation (AR) undergoing TAVR.Methods and resultsPubMed, Embase, Scopus, Web of Science and Cochrane CENTRAL were systematically searched for randomised controlled trials, observational studies and case reports published from inception to 2 April 2020, involving patients of Asian ethnicity with pure native aortic regurgitation who had undergone TAVR. Our primary outcome was all-cause mortality, with secondary outcomes including all major complications. Five studies (n=274 patients) and eight case reports were included. Device success was reported in 94.9% of the patients, the all-cause mortality rate was 4.4%, 2.5% were converted to SAVR, 1.7% had post-operative paravalvular leak and 6.7% required permanent pacemaker implantation.ConclusionsTAVR has demonstrated acceptable safety and efficacy in Asian patients with pure AR displaying low mortality rates and few adverse outcomes.

Project description:BackgroundAortic regurgitation (AR) is a condition associated with significant morbidity and mortality, particularly in severe cases. The J-Valve system, next-generation transcatheter heart valve, may overcome the procedural challenges associated with treating pure AR. This study reported the outcome of use of the J-Valve for treatment of AR.MethodsThis study observed 47 patients undergoing transcatheter aortic valve implantation (TAVI) with the J-Valve system. Diagnostic evaluation included transthoracic echocardiography and multislice computed tomography to assess AR severity and anatomic characteristics essential for TAVI. Follow-up evaluations were conducted at various intervals postoperation to evaluate outcomes.ResultsThe patients had a mean age of 73.0 ± 9.0 years and a median ejection fraction of 58.0% (interquartile range, 45.0%-64.0%). The median European System for Cardiac Operative Risk Evaluation (EuroSCORE II) was 3.0% (interquartile range, 2.0%-6.7%). The procedural success rate was 100%, with no need for a second valve implantation or conversion to sternotomy. Short-term outcomes showed significant improvements in the New York Heart Association functional classification (P < 0.001), the left ventricular ejection fraction (P = 0.009), and the left ventricular end-diastolic diameter (P < 0.001). A singular case of valve migration and severe perivalvular leakage due to Behçet's disease prompted a revised approach incorporating immunomodulation therapy.ConclusionsTAVI with the J-Valve system presents a viable alternative for managing severe AR, demonstrating high procedural success and substantial clinical improvement. However, the case of valve migration due to Behçet's disease highlights the need for careful preoperative screening and consideration of autoimmune disorders in differential diagnoses.
