Impact of transcatheter mitral valve repair on ventricular arrhythmias

ConclusionsIn this prospective study, transcatheter mitral valve repair using MitraClip was associated with a reduced prevalence of ventricular arrhythmias. The subset of patients with persistent or new ventricular arrhythmias after MitraClip implantation showed progression of left ventricular dysfunction.

AbstractAimsThe aim of this study was to determine the incidence, predictors, and short ‐term and long‐term outcomes associated with in‐hospital sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) collectively termed ventricular arrhythmia (VA) in the heart failure (HF) patients.Methods and resultsThe HEart function Assessment Registry Trial in Saudi Arabia (HEARTS registry) is a prospective national registry of patients with chronic HF from18 tertiary care hospitals across Saudi Arabia. Diagnosis of HF was in accordance with American Heart Association/European Society of Cardiology definition cr...

ConclusionOur PPCM collective treated with standard therapy for heart failure, dopamine D2 receptor agonists, and anticoagulation displays a high and stable long ‐term recovery rate with low mortality at 5‐year follow‐up. However, long‐term use of cardiovascular medication, persisting orde novo hypertension and arrhythmias were frequent.

Abstract BACKGROUND: To investigate the relationship between the extracellular volume fraction (ECV) measured using cardiac magnetic resonance (CMR) T1 mapping and cardiac events in symptomatic adults with tetralogy of Fallot (TOF). METHODS: A total of 60 consecutive symptomatic adults (35.4±13.8 years old) with repaired TOF who were in New York Heart Association functional class 2-4 were prospectively enrolled. Native T1 values and ECV of the free walls of the right ventricle (RV), the left ventricle, and the ventricular septum were obtained by CMR T1 mapping using a 3.0T scanner and the saturation re...

This article provides a review of the aforementioned mechanisms of arrhythmogenesi s in heart failure; the role and impact of HF therapy such as cardiac resynchronization therapy (CRT), including the role, if any, of CRT-P and CRT-D in preventing VAs; the utility of both non-invasive parameters as well as multiple implant-based parameters for telemonitoring in HF; and the effect o f left ventricular assist device implantation on VAs.

ConclusionsWnt signalling inhibits Na+ channel by direct and indirect (via Tbx3) suppression of Scn5a transcription. Strategies to block TCF4 binding to Tbx3 and Scn5a promoters would represent novel strategies for cardiac-specific inhibition of Wnt pathway to rescue INa and prevent sudden cardiac deaths.

AbstractIntroductionAcute hemodynamic decompensation during catheter ablation of ventricular tachycardia is associated with increased mortality. We assessed the effectiveness of mechanical circulatory support using a micro ‐axial percutaneous assist device in preventing acute hemodynamic decompensation.Methods and resultsTwenty ‐six consecutive patients with structural heart disease undergoing 28 ventricular tachycardia ablations between May 2013 and October 2017 were included. All patients presenting with left ventricular ejection fraction

Authors: Zhang X, Liu X Abstract Mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHC) with apical aneurysm is a rare type of cardiomyopathy. It is associated with an elevated risk of ventricular arrhythmias, thromboembolism, heart failure and sudden cardiac death. The present case study reports on a patient with MVOHC and apical aneurysm who developed ventricular arrhythmias and heart failure. The patient received an implantable cardioverter defibrillator for prevention of fatal arrhythmias. Ventricular tachycardia was terminated by increased doses of amiodarone and β-blocker. Transthoracic echocard...
