Heart transplantation in a patient with infective endocarditis bridged with Impella 5.5: a case report.

Background: Infective endocarditis (IE) is a feared complication after surgical valve replacement accounting for 10% to 30% of all cases of IE. Our case is unique as we present a decompensated heart failure patient with IE who urgently needed mechanical circulatory support (MCS) to stabilize while IE was treated. We used Impella to bridge him to sterile state before heart transplant was done.

Review of anticoagulation considerations in extracorporeal membrane oxygenation support.

Since its first success in 1975, extracorporeal membrane oxygenation (ECMO) has been used with increasing frequency for pulmonary and cardiopulmonary bypass. Use in adults has increased exponentially since the early 2000s, but despite thousands of international cannulations using both veno-arterial (VA) and veno-venous (VV) ECMO, there are still significant hemocompatibility-related adverse events. Current management of anticoagulation has been based on the Extracorporeal Life Support Organization guidance published in 2014 with recent updates published in 2022.

Clinical outcomes associated with sedation and analgesia in patients supported with venoarterial extracorporeal membrane oxygenation.

Sedatives and analgesics are frequently used in critically ill adult patients requiring mechanical ventilation in the intensive care unit, but optimal agent selection and dosing in patients supported with venoarterial extracorporeal membrane oxygenation remain poorly defined. This retrospective study evaluated whether sedative and analgesic agent selection and dosing had any impact on clinical outcomes after venoarterial extracorporeal membrane oxygenation decannulation. The primary endpoint of our study was the incidence of delirium within 48 h after venoarterial extracorporeal membrane oxygenation decannulation in patients who received an empiric ⩾50% sedation reduction of benzodiazepines (N = 22, group 2) compared to those who did not (N = 10, group 1) and those who required no sedatives within 24 h prior to venoarterial extracorporeal membrane oxygenation decannulation (N = 21, group 3).

Evaluation of Systemic Heparin Versus Bivalirudin in Adult Patients Supported by Extracorporeal Membrane Oxygenation.

Systemic anticoagulation is a standard of care in adult patients supported by extracorporeal membrane oxygenation (ECMO) to prevent circuit thrombosis and subsequent thromboembolic events. Unfractionated heparin has long been considered the anticoagulant of choice, but emerging evidence reports successful ECMO runs with direct thrombin inhibitors. This retrospective study sought to determine whether bivalirudin offers distinct clinical benefits as the anticoagulant of choice in ECMO.

Advanced heart failure with preserved systolic function in nonobstructive hypertrophic cardiomyopathy: under-recognized subset of candidates for heart transplant.

Background: In hypertrophic cardiomyopathy (HCM), heart transplant has been predominantly confined to patients with systolic dysfunction. An underappreciated HCM subset comprises patients with preserved left ventricular (LV) systolic function who may also require consideration for transplantation. Therefore, we sought to define the clinical profile and occurrence of advanced heart failure among patients with nonobstructive HCM and preserved systolic function.
