Long-term Reverse Remodeling by Cardiac Resynchronization Therapy with MultiPoint Pacing: A Feasibility Study of Noninvasive Hemodynamics Guided Device Programming
Cardiac resynchronization therapy (CRT) with multipoint left ventricular (LV) pacing (MultiPoint ™ Pacing [MPP]) improves acute hemodynamics and chronic outcomes over conventional biventricular pacing (BiV), though MPP programming questions persist.
Conclusion: Our study showed that vitamin D deficiency has a significant impact in heart failure patients; it is an independent predictor of lack of midterm clinical response and long-term mortality in patients undergoing CRT. Therefore, monitoring vitamin D status of heart failure patients could be of clinical significance. PMID: 31737126 [PubMed - in process]
Authors: Singh A, Karnik R, Shah AN, Chutani S, Kantharia BK Abstract Aims: Response to cardiac resynchronisation therapy (CRT) in patients with heart failure depends on the degree of correction of electromechanical dyssynchrony between the left and right ventricles (LV, RV). It is not known whether chronic programming of interventricular (VV) intervals based on characterisation of myocardial strain at different pacing intervals performed acutely would have better long-term clinical outcomes. We hence aimed to evaluate this relationship between speckle tracking strain patterns and rates at different VV intervals an...
AbstractDetection of residual fibrotic tissue, called ghosts, after lead extraction is a new phenomenon in cardiology. This paper aims at describing the phenomenon of ghosts and determining their characteristic features. The study group consisted of 580 consecutive patients who underwent transvenous lead extraction (TLE) due to local infection, endocarditis and a superfluous lead. Each patient was clinically examined with the application of transthoracic echocardiography and transesophageal echocardiography directly before and after TLE. In the study population ghosts were detected in 110 patients (19%), and in 470 cases (...

(Massachusetts General Hospital) Research has shown that treating chemotherapy-induced cardiomyopathy with commercially available cardiac resynchronization therapy (CRT) delivered through a surgically implanted defibrillator or pacemaker can significantly improve patient outcomes.
A pacemaker-like device restored heart function in a group of cancer survivors — mostly women with breast cancer — who had suffered from heart failure as a result of chemotherapy, a study in the Journal of the American Medical Association (JAMA) reports.

This cohort study examines the association of cardiac resynchronization therapy with change in left ventricular ejection fraction (LVEF)among patients with chemotherapy-induced cardiomyopathy.
This article includes also recently announced findings on the TRANSITION study which revealed that HFrEF therapy with ARNI might be safely initiated after an acute decompensated heart failure episode, including patients with heart failure de novo and ACEI/ARB na ïve, both hospitalised or shortly after discharge, in contrary to the PARADIGM-HF trial, where patients had to be administered a stable dose of an ACEI/ARB equivalent to enalapril 10 mg a day for at least 4 weeks before the screening.
ConclusionPosture and exercise have a smaller effect on AV timing compared with atrial pacing. However, individualized optimization and dynamic rate related changes may be needed to maintain optimal fusion with left ventricular (LV) stimulation.
