The pulmonary artery vent is a plastic sump catheter that is introduced into the main pulmonary artery through a purse-string suture and connected via a roller pump to the venous reservoir of the heart-lung perfusion machine.Placement and removal require only a few minutes.ata relating to the hemodynamic efficaciousness and mechanism of action of a pulmonary artery catheter or vent used for left ventricular venting during cardiac operations are presented.
Anatomy of the coronary arteries. Your left ventricle pumps blood into the main artery of your body, called the aorta. See a picture of the heart and coronary arteries. Close to the heart, the two main coronary arteries branch off of your aorta.1  The left main coronary artery is a short vessel that branches into the: In a small number of people, the circumflex artery supplies the lower and back portions of the left ventricle. 2  The right coronary artery supplies blood to the right ventricle and then supplies the underside (inferior wall) and backside (posterior wall) of the left ventricle.
