Artificial heart valve thinners which must be tested and monitored constantly or it may be the constant ticking noise of the valve, which can be heard sometimes several feet away from the patient forever 24-7. There are three main types of artificial heart valves: the "mechanical,"the "biological," and the "tissue engineered" valves. Mechanical heart valves (MHV) are prosthetics designed to replicate the function of the natural valves of the human heart. The human heart contains four valves: tricuspid valve, pulmonic valve, mitral valve and aortic valve. Their main purpose is to maintain unimpeded forward flow through the heart and from the heart into
Mitral valve stenosis acute severe mitral regurgitation. Severe mitral regurgitation usually results from a tear in one of the valve leaflets or the subvalvular apparatus. It can lead to pulmonary edema and hemodynamic compromise, necessitating urgent surgical mitral valve replacement. Other serious complications with PBMV usually relate to the technique of trans-septal puncture (TSP). The ideal site for TSP is the region of the fossa ovalis in the inter-atrial septum. Occasionally, however, the sharp needle used for TSP may inadvertently traumatize other cardiac structures, leading to cardiac tamponade or serious blood loss. Although the immediate results of PBMV are often quite gratifying, the
