The integrity of the mitral valve is also essential to maintaining normal left ventricular geometry and function through closely coupled ventricular-valvular interactions. This review summarizes recent developm
Diagnosis and management ofmitral valve diseasedemands a thorough understanding ofmitral valveanatomyand physiology (Figs. 52.1and52.2A).19Themitral valve, or mitral apparatus, is made of four distinct parts—a fibromuscular annulus, two leaflets, multiple chordae, and twopapillary muscles. The mitral...
Mitral valve anatomy.Mitral valve anatomy and adjacent structures. Note that the anterior mitral valve leaflet does not possess scallops and its close proximity to the aortic valve. Each papillary muscle provides chordae tendineae to both valve leaflets. ALPM, anterolateral papillary muscle; PMPM, pos...
Similar to the mitral valve, the opening, and closing of the aortic valve depend on the pressure difference between the left ventricle and the aorta. During systole, the left ventricle contracts, and it causes an increment in pressure built up within the ventricle. The aortic valve opens when ...

Patients with pliable, mobile, relatively thin, minimally calcified mitral leaflets with minimal or no subvalvular stenosis are good candidates for this procedure. A TEE should be performed prior to commissurotomy to clearly define the valve anatomy and exclude the presence of a left atrial ...
Improvements of echocardiographic techniques and new insights in mitral valve anatomy and physiology have rendered the diagnosis of this condition more accurate and reliable. MVP can be sporadic or familial, demonstrating autosomal dominant and X-linked inheritance. Three different loci on chromosomes 16,...
The prevalence of mitral valve prolapse (MVP) among middle- and older-aged individuals is estimated to be 2–4% in Western countries. However, few studies have been conducted among Asian individuals and young adults. This study included a sample of 2442
Mitral Valve Annuloplasty In subject area: Medicine and Dentistry The mitral annuloplasty approach is an attempt to crimp and reshape the mitral annulus through the coronary sinus, taking advantage of the proximity of the coronary sinus with the annulus. From: Journal of the American College of ...
Devices and methods for implantation at a native mitral valve having a non-circular annulus and leaflets. One embodiment of the device includes a valve support having a first region
