The limit of application of intraaortic balloon pumping (IABP) on canine myocardial infarction. 1982

T Onitsuka, and Y Koga, and K Shibata, and M Tomita

The limit of application of intraaortic balloon pumping was evaluated in cases of canine myocardial infarction produced by either ligation of the descending coronary artery and of branches in the right coronary artery or establishment of stenosis in the left main coronary artery. The limit of application of intraaortic balloon pumping was confirmed to be as follows: 1) stenosis of seventy-five per cent or more in left main coronary artery, 2) over 45 per cent infarction of the entire left ventricular free wall, 3) endocardial viability ratio of less than 0.65, 4) blood flow of less than 18 ml/min/100 g in the left circumflex coronary artery when the left descending coronary artery was ligated, 5) and less than 0.69 in the ratio of inside blood flow to outside of the left ventricular free wall, as related to regional myocardial blood flow.

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.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
