Survey on Cardiologists' Perspectives on Cardiac Point of Care Ultrasound (POCUS).

: Cardiac point of care ultrasound (POCUS) has been used with increasing frequency. As a result of this trend, this study sought to characterize cardiologists' perspectives on cardiac POCUS. An 18-question survey on demographics, cardiac POCUS clinical practice, education, and infrastructure was distributed by 16 academic medical centers.

Left Bundle Branch Block-Induced Cardiomyopathy in a Transplanted Heart Treated With His Bundle Pacing.

A 70-year-old male with prior orthotopic heart transplant developed left bundle branch block followed by new-onset left ventricular systolic dysfunction. He underwent His bundle pacing for cardiac resynchronization therapy with complete normalization of his ejection fraction. This is the first reported case of left bundle branch block-induced cardiomyopathy in a transplanted heart.

His-bundle pacing: A novel treatment for left bundle branch block-mediated cardiomyopathy.

Background: Chronic left bundle branch block (LBBB) can lead to LBBB-mediated cardiomyopathy from left ventricular dysynchrony. His-bundle pacing (HBP) results in direct electrical synchrony using the native His-Purkinje system, providing a novel treatment for this cardiomyopathy.

Objective: To assess the feasibility of HBP for cardiac resynchronization therapy (CRT) in LBBB-mediated cardiomyopathy patients.

Long-term outcomes in patients with critical limb ischemia and heart failure with preserved or reduced ejection fraction.

The impact of heart failure (HF) on long-term survival in patients with critical limb ischemia (CLI) has not been well described. Outcomes stratified by left ventricular ejection fraction (EF) are also unknown. A single center retrospective chart review was performed for patients who underwent treatment for CLI from 2006 to 2013.
