Outcomes by cannulation methods for venovenous extracorporeal membrane oxygenation during COVID-19: A multicenter retrospective study

Omar Saeed et al.

Summary: This study aimed to determine the relationship between cannulation methods for venovenous extracorporeal membrane oxygenation (V-V ECMO) and patient outcomes. The study found that catheter-directed flow into the pulmonary artery, bypassing the right ventricle, using a single dual-lumen cannula was associated with reduced mortality in COVID-19 patients.

Right Heart Failure Management: Focus on Mechanical Support Options

Meena Bhatia et al.

Summary: Millions of American adults suffer from right heart failure (RHF), which is associated with high rates of hospitalization, organ failure, and death. The management of advanced cases can be difficult, and mechanical therapies may be necessary for patients who are refractory to medical treatment. Available mechanical assist devices for RHF include venoarterial extracorporeal oxygenation and right ventricular assist devices. Each therapy has its own advantages and limitations, and their suitability depends on the clinical context.

Temporary Right-Ventricular Assist Devices: A Systematic Review

Mahmoud Abdelshafy et al.

Summary: Acute right-sided heart failure is a complex clinical syndrome with a lack of evidence-based literature. Temporary right-ventricular assist device is a potential treatment option. This study found variations in successful t-RVAD weaning rates and 30-day survival rates. The most commonly reported complications include bleeding, acute kidney injury, stroke, and device malfunction.

Percutaneous Pulmonary Artery Cannulation to Treat Acute Secondary Right Heart Failure While on Veno-venous Extracorporeal Membrane Oxygenation

Kelly M. Ivins-O'Keefe et al.

Summary: This study describes the use of percutaneous pulmonary artery cannulation for conversion from veno-venous to veno-pulmonary artery ECMO in patients with secondary right heart failure. The technique reduced vasoactive infusion requirements, but the mortality rate remained high, with some patients experiencing complications related to pericardial effusion during emergency treatment.
