Quadrangular resection is the gold standard technique for correction of the posterior leaflet prolapse in mitral valve disease. Prompted by the idea that the anterior leaflet of the tricuspid valve corresponds to the posterior leaflet of the mitral valve in its structure and function, we conducted a quadrangular resection of the anterior leaflet of the tricuspid valve in a case of tricuspid end...

The comprehensive aortic root and valve reconstruction (CARVAR) technique comprises two main procedures, which are aortic root reduction using prosthetic rings and neo-leaflet reconstruction using a pericardial patch. Although concerns about durability of the pericardial neo-leaflet have been raised in the CARVAR technique, complications related to leaflet reconstruction have not been reported ...

Various surgical techniques have been described for the repair of mitral valve with or without using an annuloplasty ring depending upon the pathological changes. Isolated prolapse of the anterior mitral leaflet with severe mitral regurgitation is relatively uncommon compared to prolapse of the posterior mitral leaflet. The technique commonly used is edge-to-edge repair, Chordal transfer and sh...

OBJECTIVES We tested the hypothesis that patients with incomplete systolic mitral leaflet closure (IMLC: apically displaced coaptation) also have restricted diastolic leaflet opening that is independent of mitral inflow volume and provides evidence supporting increased leaflet tethering. BACKGROUND Competing hypotheses for functional mitral regurgitation (MR) with IMLC include global left ven...

OBJECTIVES Reports indicate that repair procedures for ischaemic mitral regurgitation (IMR) are less durable than previously thought. Repair failure has been shown to be stress related. Leaflet curvature is the major determinant of valve stress. Theoretical and animal experiments have shown that saddle-shaped annuloplasty optimizes leaflet curvature when compared with standard flat ring annulop...

BACKGROUND The reduction in the number of unnecessary prescriptions of antibiotics has become one of the most important objectives for primary health care. German GPs report that they are under "pressure to prescribe" antibiotics particularly in consultations with Turkish immigrants. And so a qualitative approach was used to learn more about the socio-medical context of Turkish patients in rega...

The implantation of annuloplasty rings is a common surgical treatment targeted to re-establish mitral valve competence in patients with mitral regurgitation. It is hypothesized that annuloplasty ring implantation influences leaflet curvature, which in turn may considerably impair repair durability. This research is driven by the vision to design repair devices that optimize leaflet curvature to...

A real-time, phased-array, two-dimensional echocardiography system was used to assess mitral valve motion in 30 catheterized patients with pure mitral stenosis. Suitable images for analysis of mitral valve motion were obtained in 25 patients. The valve leaflets were most thickened and immobile at the leaflet tips while maximum mobility was at the leaflet body. Diastolic movement of anterior mit...
