Injury to ascending aorta by partial-occlusion clamp during aorta-coronary bypass. 1977

I B Boruchow, and R Iyengar, and J R Jude

Disease of the proximal ascending aortic wall from prolonged, poorly controlled hypertension predisposed to intimal injury after clamp compression. This creates a spectrum of problems: (1) intimal tear with late formation of a localized aneurysm, (2) delayed acute dissecting aneurysm, and (3) intraoperative acute dissecting aneurysm. Principles of management are discussed.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D009203	Myocardial Infarction	NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).

D003327	Coronary Disease	An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

D006322	Heart Aneurysm	A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.	Cardiac Aneurysm,Aneurysm, Cardiac,Aneurysm, Heart,Aneurysms, Cardiac,Aneurysms, Heart,Cardiac Aneurysms,Heart Aneurysms

D000784	Aortic Dissection	A tear in the inner layer of the AORTA leading to interstitial HEMORRHAGE, and splitting (dissecting) of the aortic TUNICA MEDIA layer. It typically begins with a tear in the TUNICA INTIMA layer.
