Left Pulmonary Artery Ligation and Chronic Pulmonary Artery Banding Model for Inducing Right Ventricular-Pulmonary Hypertension in Sheep.

Pulmonary hypertension (PH) is a progressive disease that leads to cardiopulmonary dysfunction and right heart failure from pressure and volume overloading of the right ventricle (RV). Mechanical cardiopulmonary support has theoretical promise as a bridge to organ transplant or destination therapy for these patients. Solving the challenges of mechanical cardiopulmonary support for PH and RV failure requires its testing in a physiologically relevant animal model.

Impact of implantation time on early function of cardiac transplant.

Background: Data on out-of-ice implantation ischemia in heart transplant are scarce. We examined implantation time's impact on allograft dysfunction.

Methods: We conducted a single-site retrospective review of all primary adult heart transplants from June 2012 to August 2019 for implantation warm ischemic time (WIT), defined as first atrial stitch to aortic crossclamp removal.

A Dual-Lumen Bicaval Cannula for Venovenous Extracorporeal Membrane Oxygenation.

Background: Single-site, dual-lumen venovenous extracorporeal membrane oxygenation ECMO) facilitates mobilization, reduces recirculation, and mitigates insertion and infectious risks of an additional access site. This study reports the experience with a bicaval dual-lumen cannula that comprises a robust physical design allowing for easy and safe cannulation, precise positioning and monitoring, and appropriate physiologic support for patients with acute respiratory failure.

Methods: Statistical analysis was performed from data gathered retrospectively from the electronic medical records of 20 adult patients who were cannulated for ECMO with this bicaval dual-lumen cannula from August 2018 through May 2019.

Predictors of Stroke After Minimally Invasive Mitral Valve Surgery Without the Cross-Clamp.

Minimally invasive mitral valve surgery (mini-MVS) with hypothermic fibrillatory arrest has been associated with an increased risk of stroke. We aim to investigate the incidence, predictors, and outcomes of stroke in a large cohort of patient who underwent clampless mini-MVS. Between January 2008 and June 2017, we performed 1247 mini-MVSs.
