About

Dr. Mark A. Chaney is a leading anesthesiologist and researcher whose work centers on perioperative pain management and the safety of minimally invasive and robotic cardiac surgery. His most impactful contribution is a landmark 2021 randomized, placebo-controlled trial demonstrating that intrathecal morphine significantly reduces postoperative morphine consumption in minimally invasive cardiac surgery, a finding with over 40 citations that has directly shaped enhanced recovery protocols. Dr. Chaney has also critically examined the risks of advanced surgical techniques, notably in a 2011 study showing that multivessel beating-heart robotic revascularization increases morbidity and mortality—a cautionary finding that has influenced clinical decision-making. His expertise extends to complex cases, including the management of myocardial bridges, robotic mitral valve repair with ventricular fibrillatory arrest, and rare complications like unilateral pulmonary edema requiring ECMO. Through these contributions, totaling over 100 citations, Dr. Chaney has established himself as a pivotal voice in balancing innovation with patient safety, making his work essential reading for anesthesiologists and cardiac surgeons pursuing safer, less invasive approaches.
