Transcatheter tricuspid valve intervention (TTVI) has recently emerged as a promising alternative to surgery for tricuspid regurgitation (TR). However, a significant proportion of patients fail screening for TTVI, and little is known about their characteristics and natural history. This study sought to investigate causes of screen failure and outcomes of patients declined for TTVI.

Healthcare systems implemented contrast-saving strategies to maintain their remaining ICM supplies. This study sought to determine the impact of contrast shortage on the incidence of contrast-associated acute kidney injury (CA-AKI).

Background: The Society of Thoracic Surgeons (STS) score has been used to risk stratify patients undergoing transcatheter aortic valve replacement (TAVR). The Transcatheter Valve Therapy (TVT) score was developed to predict in-hospital mortality in high/prohibitive-risk patients. Its performance in low and intermediate-risk patients is unknown.

However, it is difficult to isolate and evaluate pulmonary recovery independent of cardiac function on venoarterial ECMO. In this case report, we demonstrate the advantage of supporting a patient in cardiopulmonary failure with venovenous ECMO and the Impella 5.

This report describes a process of using directed hypercapnia in 5 patients to wean them from prolonged extracorporeal support secondary to refractory hypercarbic respiratory failure.

We report the outcomes of 3 patients with massive pulmonary embolism treated successfully with catheter-directed thrombolytic therapy and venoarterial extracorporeal membrane oxygenation.

Associated with significant morbidity and mortality, neurological complications in adult patients with left ventricular assist devices (LVAD) approaches a prevalence as high as 25%. As the number of individuals using LVAD support grows, it is increasingly important for providers to understand the hematologic and hemodynamic changes associated with LVAD implantation, the risk factors for neurological complications and their mitigation strategies. Areas covered: PubMed searches were completed using the terms 'Left ventricular assist device and stroke' (994 results) then 'Left ventricular assist device and stroke risk factors' (199 results).
