Right heart failure is a relatively common complication after left ventricular assist device (LVAD) implantation. Severe right heart failure can be managed by temporary right ventricular assist device (RVAD) implantation. However, trans-sternal RVAD insertion requires a subsequent third sternotomy for cannula removal. Herein, we present a case of RVAD insertion via a left anterior mini-thoracotomy after LVAD implantation in a patient with alcohol-induced cardiomyopathy.

Purpose: The design and development of ventricular assist devices have heavily relied on computational tools, particularly computational fluid dynamics (CFD), since the early 2000s. However, traditional CFD-based optimization requires costly trial-and-error approaches involving multiple design cycles. This study aims to propose a more efficient VAD design and optimization framework that overcomes these limitations.

This analysis evaluates the longitudinal impact of extracorporeal membrane oxygenation (ECMO) and ventricular assist device (VAD) on the progression of motor delay and cognitive delay in pediatric heart transplant recipients. The United Network for Organ Sharing Registry was queried for pediatric patients (<18 years) who received a heart transplant between 2008 and 2022 and were bridged-to-transplantation with either ECMO or VAD. Patients were further stratified based on the progression of delay status pretransplant to post-transplant.

Aims: Non-pharmacological therapies for acute decompensated heart failure (HF) and cardiogenic shock have evolved considerably in recent decades. Short-term mechanical circulatory support (MCS) devices can be used as circulatory backup. While nearly all available devices use continuous flow, evidence indicates that pulsatile flow can be more effective.

We describe a modified Park's stitch technique incorporating systematic free margin alignment to achieve complete elimination of aortic regurgitation in patients with a left ventricular assist device. The technique involves a two-step approach: first, free margin alignment of all three cusps using single interrupted 6-0 polypropylene sutures placed at the nodules of Arantius to achieve precise coaptation, followed by conventional Park's stitch using mattress sutures with autologous pericardial pledgets for central closure. The alignment sutures remain in place to provide reinforcement.
