Careful anesthetic management and advanced hemodynamic monitoring are crucial during infrarenal aortic cross-clamping in patients with abdominal aortic aneurysm who have concomitant severe coronary artery disease and aortic regurgitation, as they are at high risk for acute decompensation and cardiac arrest.
Warrants extreme caution with infrarenal aortic cross-clamping in severe CAD and AR; case report leaves open optimal monitoring strategies.
Patients with chronic aortic regurgitation have a hemodynamically fragile equilibrium; increased afterload during infrarenal aortic cross-clamping and acute decompensation. The tolerance of patients with severe coronary artery disease to the stress of infrarenal aortic cross-clamping differs from patients without overt coronary artery disease. Therefore, careful anesthetic management is needed during infrarenal aortic cross-clamping in patients with aortic regurgitation and coronary artery disease. We describe the anesthetic management of a man with an infrarenal aortic aneurysm that underwent cardiac arrest after aortic-cross clamping for aortoiliac bypass surgery.

Jeon et al. (2009) conducted a case report in Abdominal aortic aneurysm with coronary artery disease and aortic regurgitation (n=1). Infrarenal aortic cross-clamping was evaluated on Cardiac arrest. A 66-year-old man with severe coronary artery disease and aortic regurgitation experienced cardiac arrest after infrarenal aortic cross-clamping during aortoiliac bypass surgery.
