Predictors of myocardial recovery in arrhythmia-induced cardiomyopathy: A multicenter study.

Background: Arrhythmia-induced cardiomyopathy (AIC) is characterized by improvement in left ventricular ejection fraction (LVEF) following arrhythmia treatment. Predictors of recovery in LVEF are not well understood.

Objective: We evaluated predictors of AIC recovery in a large multicenter cohort.

Perioperative predictors of permanent pacing and long-term dependence following tricuspid valve surgery: a multicentre analysis.

Aims: Permanent pacemaker placement (PPM) is often required after valvular surgery and is especially common following tricuspid valve surgery [tricuspid valve repair or replacement (TVR)]. Literature suggests that surgical intervention for isolated tricuspid valve disease is becoming more prevalent. Predictors of PPM dependency following TVR are currently unknown and would be clinically useful from a prognostication standpoint.
