11 MONGREL DOGS WERE USED TO STUDY THE EFFECT OF A CATHETER MOUNTED VALVE ON THE CORONARY ARTERIAL CIRCULATION AND THE AORTIC PRESSURE DURING CORRECTION OF ACUTE EXPERIMENTAL AORTIC REGURGITATION. 1) THE CORRECTION OF AORTIC PRESSURE (DISTAL TO THE POSITION OF THE BALLOON VALVE) IN AORTIC REGURGITATION CAN BE ACHIEVED BY POSITIONING THE BALLOON VALVE AT ANY LEVEL. FROM THE AORTIC RING TOTHE DESCENDING (THORACIC) AORTA (POSITION 2, 3, 4). 2) THE CORONARY FLOW INCREASED AND ITS PATTERN CHANGED TO BECOME MAINLY DIASTOLIC ONLY WHEN THE BALLOONVALVE WAS PLACED IN THE AORTIC RING. 3) THE CORONARY FLOW DID NOT CHANGE SIGNIFICANTLY IF THE BALLOON VALVE WAS PLACED IN THE DESCENDING (THORACIC) AORTA,WHILE IT DECREASED IF THE BALLOON VALVE WAS PLACED IN THE ASCENDING AORTA. 4)THE FUNCTION OF THE BALLOON VALVE WITHIN THE LEFT VENTRICULAR CAVITY DID NOT AFFECT THE CORONARY FLOW AND THE AORTIC PRESSURE.
