Mechanical Circulatory Support Devices

Three intra-aortic blood pumps were evaluated and compared using CFD simulations. The aim of this study is to evaluate the hemodynamic performance and calculate the hemolytic potential of the pumps. The flow fields generated by the pumps were simulated using CFD with a wall-modeled large eddy simulation (WMLES) approa…

OBJECTIVE: Accurate estimation of left ventricular ejection fraction (LVEF) after ST-segment elevation myocardial infarction (STEMI) is essential for optimizing long-term management and cardiovascular risk stratification. This study aimed to identify predictors of LVEF at six months after STEMI and to develop a clinic…

Opioid analgesics, particularly morphine and fentanyl, remain used in acute myocardial infarction (AMI) to relieve severe ischaemic pain and attenuate pain-driven sympathetic activation. Their role has become more complex in contemporary reperfusion care because μ-opioid receptor activation in the enteric nervous syst…

Spontaneous coronary artery dissection (SCAD) is an important cause of acute myocardial infarction in women without significant atherosclerotic coronary artery disease. Recurrent SCAD progressing to advanced heart failure requiring durable mechanical circulatory support is exceptionally uncommon. A 45-year-old woman w…

Introduction With the increasing utilization of left ventricular assist devices (LVADs) as a pivotal treatment option for end-stage heart failure, the rehospitalization of patients equipped with these devices has emerged as a significant issue impacting both quality of life and healthcare costs. This study evaluates r…

Background/Objectives: Direct comparative evidence regarding aortic root and pulmonary artery venting during on-pump coronary artery bypass grafting (CABG) remains limited. We evaluated whether pulmonary artery venting was associated with improved early postoperative respiratory recovery compared with aortic root vent…
