Background Standard mitral valve replacement (MVR) in patients with chronic mitral regurgitation results in consistent reductions in resting postoperative ejection fraction. This has been attributed to removal of the low-impedance ejection pathway into the left atrium or to disruption of the chordal apparatus. Mitral valve repair (MVP) does not reduce ejection fraction at rest. However, whether...

The dermatoglyphs of 50 Singapore school children with mitral valve prolapse (MVP) were studied, with special reference to the frequency of digital arches. The MVP was diagnosed clinically and substantiated by two dimensional echocardiography. In the study there were 35 Chinese and 15 Malay children, with ages ranging from 6 to 19 years. Four Chinese children had one or more arches on the digit...

BACKGROUND AND AIM OF THE STUDY A new mitral valve repair concept to treat mitral regurgitation (MR) due to valve prolapse was recently proposed. In this study, an improved design of this concept is presented, and the results of preliminary hemodynamic studies conducted in an in-vitro prolapse model are reported. METHODS The new repair approach is based on using a web/net attached to a standa...

Mitral valve plasty (MVP) is preferred over mitral valve replacement (MVR) for mitral regurgitation in humans because of its favorable effect on quality of life. In small dogs, it is difficult to repair multiple lesions in both leaflets using MVP. Herein, we report a case of severe mitral regurgitation caused by multiple severe lesions in the posterior leaflet (PL) in a mixed Chihuahua. Initial...

In patients with mitral valve prolapse syndrome various disturbances of cardiac rhythm can be observed such as atrial arrhythmias, ventricular tachycardias and conduction disturbances. Of timely interest are the questions of which etiology is at the basis of the arrhythmias, what is their relevance with respect to sudden cardiac death, what are the indications for treatment and which therapeuti...

BACKGROUND The aims of this study are to evaluate the accuracy of low dose multidetector computed tomography coronary angiography (MDCT) versus invasive coronary angiography (ICA) in ruling out CAD in patients with mitral valve prolapse and severe mitral regurgitation (MVP) before cardiac surgery and to compare the overall effective radiation dose (ED) and cost of a diagnostic approach in which...

BACKGROUND There is an increasing interest in minimally invasive cardiac surgery. METHODS AND RESULTS Since February 1, 1997 till April 1, 2002, 306 patients underwent endoscopic mitral valve surgery (226 repair, MVP; 80 replacement, MVR). Predominant valve pathology was degenerative in MVP (83.6%) and rheumatic in MVR (65%). Mean age was 61.5+/-12.9 years. Median preoperative functional clas...

Introduction Mitral Valve Prolapse (MVP) is the most common cardiac valve pathology of to day. Aim of article was to identify the types and frequency of potentially malignant arrhythmia and atrial brillation in patients with MVP, to determine the differences in these arrhythmias between classical and non-classical MVP, to evaluate the correlation of potentially malignant arrhythmia and atrial f...

Abstract Introduction Mitral Valve Prolapse (MVP) is associated with complex ventricular arrythmia (VA) and sudden cardiac death but risk stratification remains unclear. Exercise induces an hyperadrenergic state could trigger VA, however, data on exercise-induced VA (EIVA) in MVP patients are scarce. Objective To describe EIVA prevalence, origin, characteristics features patients. Methods In th...
