Abstract

Patients with coronary chronic total occlusions (CTO) often have concurrent higher-risk anatomy and physiology (significant calcium, left ventricular dysfunction, multivessel disease) that increase their procedural risk. We present a retrospective multicenter case series describing use of the Impella percutaneous ventricular assist device (p-VAD) during CTO PCI. We performed a retrospective analysis of self-reported data from five large referral centers from 2013 to 2017 and identified patients that underwent elective, hemodynamically supported CTO PCI with the Impella p-VAD device (2.5 or CP). Preprocedural demographics, procedural invasive hemodynamics and characteristics, and in-hospital outcomes were reported. About 57 patients (2% of the overall CTO volume of these centers) were included in this retrospective cohort. The primary indication in the majority (78.9%) of cases was chronic angina; in 21.1% the primary indication was for chronic congestive heart failure because of an ischemic cardiomyopathy. The median LVEF was 20% (15%, 30%) and 63.2% were surgical turndowns. Significant proportions of the group underwent multivessel PCI (91.2%), intervention on an unprotected left main or last remaining conduit vessel (35.1%), ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Artificial Heart & Ventricular Assist Devices

Total artificial hearts (TAH) and ventricular assist devices (VADs) provide cardiac support for patients with end-stage heart disease and have significantly improved the survival of these patients. Discover the latest research on Artificial Heart and Ventricular Assist Devices here.
