The geometric or anatomic diagnosis of mitral valve prolapse, as opposed to the pathologic diagnosis of myxomatous valve disease, is based on the relationship of the mitral leaflets to the surrounding anulus. Current echocardiographic criteria for this diagnosis include leaflet displacement above the annular hinge points in any two-dimensional view; implicit in this equivalent use of intersecti...

n engl j med 361;23 nejm.org december 3, 2009 2261 This Journal feature begins with a case vignette that includes a therapeutic recommendation. A discussion of the clinical problem and the mechanism of benefit of this form of therapy follows. Major clinical studies, the clinical use of this therapy, and potential adverse effects are reviewed. Relevant formal guidelines, if they exist, are prese...

Marfan's syndrome (MFS) is an inherited autosomal dominant disorder of connective tissue with mutation on the fibrillin-1 gene encoding for fibrillin. This frequently involves the cardiovascular system with prevalence is 1:5000-10,000. The clinical major criteria involve the skeletal and ocular apparatus and the cardiovascular and central nervous system. In Marfan's syndrome mitral valve prolap...

The aetiology of sudden cardiac arrest can often be identified to underlying cardiac pathology. Mitral valve prolapse is a relatively common valvular pathology with symptoms manifesting with increasing severity of mitral regurgitation (MR). It is unusual for severe MR to be present without symptoms, and there is growing evidence that this subset of patients may be at increased risk of sudden ca...

Three age- and symptom-matched groups of patients with a hypermobility score of 5-9, 3-4, and 0-2 (controls), respectively, were examined for clinical and echocardiographic evidence of mitral valve prolapse and other stigmata of a collagen disorder. Mitral valve prolapse, a reduced upper segment/lower segment mitral ratio, reduced skin thickness, spinal anomalies, and a history of fracture were...

BACKGROUND A paucity of data exists regarding the prevalence and relationship of hypomagnesaemia with clinical symptoms of mitral valve prolapse (MVP) in pediatric patients. OBJECTIVE In this study we evaluated the prevalence of magnesium (Mg) deficiency in pediatric patients with MVP syndrome and attempted to clarify the effect of Mg therapy on alleviating their symptoms. METHODS The prese...

BACKGROUND We evaluated the midterm outcomes of lifting posterior mitral annuloplasty for enhancing leaflet coaptation in mitral valve repair. METHODS Between October 2007 and December 2012, 341 consecutive patients with significant mitral regurgitation underwent lifting posterior mitral annuloplasty using a specially designed fabric annuloplasty strip that lifts the middle portion of the pos...

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS). It is a major cause of prosthetic valve endocarditis; mitral valve prolapse (MVP) has emerged as a prominent predisposing structural cardiac abnormality. We describe a case of Staphylococcus lugdunensis endocarditis in an 18-year-old woman with preexisting mitral valve prolapse complaining of fever, a one-month history of ...

Mitral valve repair is currently considered the standard treatment for mitral regurgitation. Posterior leaflet prolapse has been treated by quadrangular resection and ring annuloplasty for many years. Although it is a classic and reproducible method, this technique may predispose to systolic anterior motion (SAM) of the anterior leaflet of the mitral valve. The incidence of SAM has been reporte...

In this paper we present a multimethod approach for induction of a specific class of classifiers, which can assist physicians in medical diagnosing in the case of mitral valve prolapse. Mitral valve prolapse is one of the most controversial prevalent cardiac condition and may affect up to ten percent of the population and in the worst case results in sudden death. MultiVeDec is a general framew...
