Elucidating the mechanisms underlying left ventricular function recovery in patients with ischemic heart failure undergoing surgical remodeling: A 3-dimensional ultrasound analysis.
The study objective was to elucidate the mechanisms of left ventricle functional recovery in terms of endocardial contractility and synchronicity after surgical ventricular reconstruction. ⋯ At 6-month follow-up, surgical ventricular reconstruction was associated with significant recovery in global left ventricle function, improved mechanical dispersion indicating a more synchronous left ventricle contraction, and improved left ventricle fiber shortening mostly in the basal region, suggesting the major role of the remote myocardium in enhancing left ventricle functional recovery.

Aortic valve reintervention after transcatheter aortic valve replacement.
Despite the rapid adoption of transcatheter aortic valve replacement (TAVR), there are scant data regarding aortic valve reintervention after initial TAVR. ⋯ Repeat TAVR procedure was frequently not feasible because of unfavorable anatomy and/or the need for concurrent cardiac procedures. Careful assessment of TAVR procedure repeatability should be weighed at the initial TAVR workup especially in younger patients who are expected to require a valve reintervention.
