Telocytes in human heart valves

Journal of Cellular and Molecular Medicine, 2014
Valve interstitial cells (VICs) are responsible for maintaining the structural integrity and dynamic behaviour of the valve. Telocytes (TCs), a peculiar type of interstitial cells, have been recently identified by Popescu's group in epicardium ...

Mitral valve replacement on a beating heart

Indian Journal of Thoracic and Cardiovascular Surgery, 2004
We report the case of a patient who needed mitral valve replacement but was at a high risk of myocardial injury with the conventional technique (cardioplegic arrest on cardiopulmonary bypass). Valve replacement was carried out on a beating heart on cardiopulmonary bypass by perfusing the heart continuously with oxygenated noncardioplegic normothermic ...

Transapical Beating Heart Mitral Valve Repair [PDF]

Circulation: Cardiovascular Interventions, 2010
Repair of mitral valve (MV) leaflet prolapse using chordal replacement is an established procedure in open heart surgery for the treatment of mitral regurgitation (MR). The technique has proven high reproducibility and excellent long-term outcomes for posterior leaflet prolaspe, with freedom from valve-related reoperation of >95%.1, 2 Striving toward a

Quadrivalvular rheumatic heart disease

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
Rarely, rheumatic heart disease (RHD) involves all the four valves and causes could be rheumatic, congenital, infective, or degenerative. Here, we report a case of a 42-year-old female known case RHD for 30 years and underwent closed mitral ...

Mitral valve size measurement in North Karnataka by using cardiac sizer: A cadaveric study

Archives of Medicine and Health Sciences, 2013
Background: Heart is a vital organ of circulatory system. Valves maintain the unidirectional flow of blood. Mitral valve (MV) prevents the backflow of blood into the left atrium. For the proper functioning of the heart, all valves should be intact.

Outcomes of transcatheter mitral valve replacement for degenerated bioprostheses, failed annuloplasty rings, and mitral annular calcification

European Heart Journal, 2018
Aims We sought to evaluate the outcomes of transcatheter mitral valve replacement (TMVR) for patients with degenerated bioprostheses [valve-in-valve (ViV)], failed annuloplasty rings [valve-in-ring (ViR)], and severe mitral annular calcification [valve ...

Prosthetic valve endocarditis secondary to Tropheryma whipplei in a patient with chronic polyarthritis

Journal of Cardiothoracic Surgery, 2023
Background Whipple’s disease is a chronic multisystemic infectious disease that rarely presents as culture-negative endocarditis. Most patients reported with Tropheryma whipplei endocarditis involve a native valve and few describe prosthetic valve ...

Study of mitral valve in human cadaveric hearts

Heart Views, 2012
The mitral valve is a complex structure that is altered by disease states. The classical image of the mitral valve is a bicuspid valve with two leaflets and two papillary muscles. The reason for the present study is to study the morphology and morphometry of the mitral valve.This study was carried out on 116 human cadaveric hearts.

Degenerative processes in bioprosthetic mitral valves in juvenile pigs

Journal of Cardiothoracic Surgery, 2011
Background Glutaraldehyde-treated bioprosthetic heart valves are commonly used for replacement of diseased heart valves. However, calcification and wear limit their durability, and the development of new and improved bioprosthetic valve designs is needed
