Surgical treatment of left main coronary artery disease: operative risk. 1980

B Brandt, and C B Wright, and D B Doty, and N P Rossi, and J L Ehrenhaft

Surgical experience with 100 consecutive patients with left main coronary artery stenosis (greater than 50%) was reviewed to determine the risk factors and their relationship to preoperative use of intraaortic balloon (IAB). The 30-day mortality rate was 3% and the perioperative infarction rate was 2%. There was no correlation between surgical mortality and ejection fraction (EF) (15% had EF of less than 40%), degree of stenosis (58% of the patients had greater than 70% left main stenosis), right coronary artery stenosis (81%), or the number of grafts placed. We conclude that surgery for left main coronary artery disease can be done with a low mortality rate by strict attention to the induction of anesthesia, surgical technique, and complete revascularization. In our experience, prophylactic use of the IAB does not appear to be justified and is only rarely necessary for postoperative support (one case).

UI	MeSH Term	Description	Entries
D007423	Intra-Aortic Balloon Pumping	Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.

D011300	Preoperative Care	Care given during the period prior to undergoing surgery when psychological and physical preparations are made according to the special needs of the individual patient.

D002302	Cardiac Output	The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).	Cardiac Outputs,Output, Cardiac,Outputs, Cardiac
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.
