Why the study?
New onset regional wall motion abnormality after coronary artery bypass grafting adversely affects outcomes, and early detection and addressing the cause improves morbidity and mortality.
Intraoperative TEE with speckle tracking echocardiography can rapidly detect early myocardial ischemia caused by mechanical graft compression after CABG, allowing for immediate surgical correction.
Answers are grounded in this paper and cite their sources.
Pericardial drain compression may cause reversible post-CABG ischemia identifiable by TEE; case report leaves open need for systematic evaluation.
New onset regional wall motion abnormality (RWMA) following coronary artery bypass grafting adversely affects the patient outcome. Early detection and addressing the cause of RWMA improves overall morbidity and mortality of the patient. We report a rare case of early myocardial ischemia detected by intraoperative transesophageal echocardiography due to mechanical compression of a vein graft by a pericardial drain tube.
