Clinical outcome of critically ill, not fully recompensated, patients undergoing MitraClip therapy

2014

Aims As periprocedural risk is low, MitraClip implantation is often performed in critically ill, not fully recompensated patients, who are in NYHA functional class IV at the time of the procedure, to accelerate convalescence. We herein sought to evaluate the procedural and 30-day outcome of this patient group. Methods and results A total of 803 patients undergoing MitraClip implantation were included in the German Mitral Valve Registry, and 30-day outcomes were prospectively assessed. Patients were separated based on NYHA functional class [(NYHA IV (n = 143), III (n = 572), and I/II (n = 88)]. No difference was noted in co-morbities and echocardiographic parameters of LV function between gr…

Impact of Proportionality of Secondary Mitral Regurgitation on Outcome After Transcatheter Mitral Valve Repair

2020

The purpose of this paper was to evaluate the impact of proportionality of secondary mitral regurgitation (SMR) in a large real-world registry of transcatheter edge-to-edge mitral valve repair (TMVr) BACKGROUND: Differences in the outcomes of recent randomized trials of TMVr for SMR may be explained by the proportionality of SMR severity to left ventricular (LV) volume.The ratio of pre-procedural effective regurgitant orifice area (EROA) to LV end-diastolic volume (LVEDV) was retrospectively assessed in patients undergoing TMVr for severe SMR between 2008 and 2019 from the EuroSMR registry. A recently proposed SMR proportionality scheme was adapted to stratify patients according to EROA/LVE…

Association of transcatheter direct mitral annuloplasty with acute anatomic, haemodynamic, and clinical outcomes in severe mitral valve regurgitation.

2020

Abstract Aims Several approaches for transcatheter mitral valve repair for functional mitral valve regurgitation are established. Interventional direct annuloplasty is a novel trans‐venous, trans‐septal approach. While feasibility was proven recently, knowledge on its influence on cardiac dimensions, pressures, biomarkers, and clinical outcomes is sparse. Methods and results Patients consecutively treated with direct annuloplasty‐only procedures between December 2015 and April 2018 were included in this monocentric analysis. Echocardiographic measurements, biomarker levels, clinical status [New York Heart Association (NYHA) class and 6 min walk test] were assessed at baseline, at discharge,…

Pre-Operative Modeling of Transcatheter Mitral Valve Replacement in a Surgical Heart Valve Bioprosthesis

2020

Obstruction of the left ventricular outflow tract (LVOT) is a common complication of transcatheter mitral valve replacement (TMVR). This procedure can determine an elongation of an LVOT (namely, the neo-LVOT), ultimately portending hemodynamic impairment and patient death. This study aimed to understand the biomechanical implications of LVOT obstruction in a patient who underwent TMVR using a transcatheter heart valve (THV) to repair a failed bioprosthetic heart valve. We first reconstructed the heart anatomy and the bioprosthetic heart valve to virtually implant a computer-aided-design (CAD) model of THV and evaluate the neo-LVOT area. A numerical simulation of THV deployment was then deve…

The influence of severe mitral regurgitation on major adverse cardiac and cerebrovascular events after myocardial infarction in 1-year follow-up: Dat…

2023

Background: Mitral regurgitation (MR) is frequently observed in patients with myocardial infarction (MI). However, the incidence of severe MR in contemporary population is unknown. Aims: The study evaluates the prevalence and prognostic impact of severe MR in contemporary population of patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Methods: The study group consists of 8062 patients enrolled in the Polish Registry of Acute Coronary Syndromes over the years 2017‒2019. Only the patients with full echocardiography performed during the index hospitalization were eligible. Primary composite outcome was 12-month major a…
