From 1981 to 1999 Mitral bileaflet prosthesis was implanted to 90 patients. Doppler echocardiography was performed for these patients between January and March 2002 with a mean deadline of 111 months after the intervention. 36 were women (40%) and 54 were men (60%) the mean age was 41 years (20 - 70 years) The mitral bileaflet prosthesis was a Saint Jude in 65 cases, Jyros 8 cases, Carbomédics 7 cases, Sorin Bicarbon 7 cases, Edwards Duromédics 2 cases et an ON-X in one case. The maximal transprosthetic gradient was 15.7 mm Hg +/- 5.06 (6.25 mm Hg). The mean transprosthetic gradient was 5.6 mm Hg +/- 1.07 (39.5 mmHg). The mean prosthesis functional area 2.37 cm2 +/- 0.44 (1.75 cm2 et 3.60 cm2). Maximal gradient, mean gradient and prosthesis functional area are independent from kind mitral bileaflet prosthesis and from the prosthesis size.

Background: A subset of patients with mitral valve prolapse (MVP), a highly heritable condition, experience sudden cardiac arrest (SCA) or sudden cardiac death (SCD). However, the inheritance of phenotypic imaging features of arrhythmic MVP remains unknown.
Methods: We recruited 23 MVP probands, including 9 with SCA/SCD and 14 with frequent/complex ventricular ectopy.

Purpose To determine the prevalence of mitral annular disjunction (MAD) in patients undergoing cardiac MRI for various clinical indications and to assess the association of MAD with arrhythmia, mitral valve prolapse (MVP), and myocardial alteration. Materials and Methods This study analyzed data from a retrospective observational registry of consecutive patients undergoing cardiac MRI for different clinical indications. Cardiac MRI examinations were performed from January 2019 to June 2019 at 13 Italian hospitals.

The "respect" approach to surgical mitral valve repair, which involves implanting artificial neochordae, is gaining increased adoption. Surgeons are possibly prone to error in the manual construction of neochordae, which can lead to prolonged cross-clamp times. Novel systems such as Chord-X Pre-Measured Loops (On-X Life Technologies, Inc.
