The Golden Proportion is a particular geometric ratio between two segments. It results in an irrational number, commonly rounded to 1.618, or 0.618, and showing unique geometrical/mathematical properties. Its presence has been documented in a huge amount of natural settings, as well as the human body and the heart. In light of a previous research of ours, about its presence in the Coaptation Triangle, we investigated the dimensions of both mitral leaflets in healthy mitral valves and then compared our results to literature data, in order to search whether this proportional pattern could be extended to other valve aspects.

The aim of this study was to quantify the acute dynamic changes of mitral valve (MV) geometry throughout the cardiac cycle-during percutaneous MV repair with the MitraClip system by 3-dimensional tran...
Mitral valve repair is well-developed and allows for successful reconstruction of selected rheumatic valve pathologies. Rheumatic aortic valve repair also has been successful, employing techniques suc...
Mechanisms of chronic ischaemic mitral regurgitation (IMR) are well-characterized by apically tethered leaflet caused by papillary muscles (PMs) displacement and adynamic mitral apparatus. We investig...
It is not unanimous among scientists if there is beauty in science. Some deny it. Mental clarity of conclusions when captured in simple looking equations is mathematical beauty. This we also find in t...
The aim of this study was to describe normal electrocardiogram patterns and values in two species of conscious pheasants (golden and silver). The standard bipolar and augmented unipolar limb leads ele...
Mitral insufficiency (MI) accounts for 24% of adult valvulopathies and affects 7% of subjects older than 75 years. They are the second leading cause of valvulopathy in Europe. The most com...
The purpose of the study is to demonstrate the long term safety and effectiveness of the Carpentier-Edwards® PERIMOUNT Magna Mitral Valves in patients undergoing mitral valve replacement ...
Ischemic mitral regurgitation is a disease where the mitral valve is regurgitant, or leaking, as a result of changes in the muscle of the heart caused by coronary artery disease Ischemic m...
The purpose of the study is to provide evidence of safety and effectiveness of the study valve. The rationale is to offer a replacement mitral valve for patients with anatomy that is too...
Prospective, observational, multi-center trial in which patients with mitral regurgitation sufficient to merit mitral valve repair will receive a surgical transvalvular, intra-annular Mitr...
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
Heart murmurs which are systolic in timing. They occur between the first and the second HEART SOUNDS, between the closure of MITRAL VALVE and TRICUSPID VALVE and the closure of semilunar aortic and pulmonary valves. Systolic murmurs include ejection murmurs and regurgitant murmurs.
A family of Primates of the suborder Strepsirhini containing six genera. The family is distributed in parts of Africa, India, Asia, and the Philippines. The six genera are: Arctocebus (golden potto), GALAGO (bush babies), Loris (slender loris), Nycticebus (slow loris), and Perodicticus (potto). Lorises and pottos are relatively common except for Arctocebus, the golden potto. All are arboreal and nocturnal.
Devices, usually incorporating unidirectional valves, which are surgically inserted in the sclera to maintain normal intraocular pressure.
