Carlon et al reported the first superior cavo-pulmonary anastomosis between the right pulmonary artery and azygos vein, demonstrated an increase in pulmonary blood flow in dogs. [17] The Glenn group at Yale worked on several strategies to create anastomoses between the superior or inferior vena cavae to the right or main pulmonary arteries.
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign.
The entire surgery lasts five hours, during which time the dog is connected to a blood oxygenator and the heart is bypassed. The defective heart valve is removed and the replacement valve, typically from bovine pericardium, is precisely sewn into place. The dog’s heart is then restarted and monitored for at least two hours after the surgery ...
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery, and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves , the other being the aortic valve .
Percutaneous valve replacement An alternative to open heart surgery, percutaneous valve replacement is the replacement of a heart valve using percutaneous methods. This is performed on the aortic valve (percutaneous aortic valve replacement/TAVI procedure), pulmonary valve and recently the mitral valve Percutaneous valve repair
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. [1]
Balloon valvuloplasty: [13] Procedure used to alleviate pain symptoms from cardiac problems such as pulmonic, mitral, and tricuspid stenosis. The purpose of this procedure is to create a smoother blood flow throughout the body by reducing harmful effects from obstructed heart valves. It is considered a minimally invasive procedure.
Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair .
