Minimally Invasive Direct Coronary Artery Bypass: An Evolving Paradigm Over the Past 25 Years.

Objective: We have routinely utilized minimally invasive direct coronary artery bypass (MIDCAB) for revascularization of the left anterior descending (LAD) coronary artery. We examined how this procedure has evolved.

Methods: A retrospective review was undertaken of 2,283 consecutive patients who underwent MIDCAB between 1997 and 2021.

Deep Versus Moderate Hypothermia in Acute Type A Aortic Dissection: A Propensity-Matched Analysis.

Background: The ideal temperature for hypothermic circulatory arrest (HCA) during acute type A aortic dissection (ATAAD) repair has yet to be determined. We examined the clinical impact of different degrees of hypothermia during dissection repair.

Methods: Out of 240 cases of ATAAD between June 2014 and December 2019, 228 patients were divided into two groups according to lowest intraoperative temperature: moderate hypothermic circulatory arrest (MHCA) (20-28°C) versus deep hypothermic circulatory arrest (DHCA) (<20°C).
