comes in mitral regurgitation due to flail leaflets a multicenter European study. Predicting left ventricular dysfunction after valve repair for mitral regurgitation due to leaflet prolapse: additive value of left ventricular end-systolic dimension to ejection fraction. A. Primum non nocere: the case for watchful waiting in asymptomatic 'severe' degenerative mitral regurgitation. et al. Influen...

In hypertrophic cardiomyopathy (HCM), rupture of mitral chordae tendineae is infrequent and causes acute haemodynamic deterioration. A 38 year old male patient had chordae rupture leading to prolapse of both mitral leaflets and severe regurgitation, without change in symptomatic status. One year before, he had had mild mitral regurgitation and a resting left ventricle outflow tract of 105 mm Hg...

The MitraClip system is a device for percutaneous edge-to-edge reconstruction of the mitral valve in patients with severe mitral regurgitation who are deemed at high risk for surgery. Studies have underlined the therapeutic benefit of the MitraClip system for patients at extreme and high risk for mitral valve surgery, suffering from either degenerative or functional mitral regurgitation. The Mi...

OBJECTIVE To determine the prevalence and characteristics of left sided valvar regurgitation in normal children and adolescents. DESIGN Prospective observational study. SETTING Tertiary paediatric referral centre. PATIENTS 329 volunteers (194 male, 135 female, age range 3-18 years). MAIN OUTCOME MEASURES Detection of regurgitation with colour flow mapping after valve closure. Measuremen...

The efficacy of balloon dilatation of the mitral valve by a bifoil (2 x 19 mm) or trefoil (3 x 15 mm) catheter (single catheter technique) was assessed in 53 patients (mean age 28) with mitral stenosis, most of whom were women. The procedure was unsuccessful in three patients. After balloon dilatation the left atrial pressure decreased from 22 mm Hg to 13 mm Hg and the mitral valve gradient fro...

Background Recent studies have shown that echocardiography and MRI are often discordant when assessing the severity of mitral regurgitation (MR), with echocardiography often overestimating severity of mitral regurgitation compared to MRI (1). This is particularly true among patients who underwent mitral valve surgery based on echocardiographic assessment and the current ACC/AHA recommendations ...

Two hundred Carpentier-Edwards, Björk-Shiley, and Starr-Edwards prostheses in 173 patients were examined. Sixteen (16%) in the aortic and 24 (25%) in the mitral position were associated with clinical signs of regurgitation. A phased array system (Hewlett-Packard A77020A) with a 2.5 MHz duplex and 1.9 MHz continuous wave transducer was used. Colour flow mapping showed trivial transvalvar regurgi...

Percutaneous Transvenous Mitral Annuloplasty for mitral regurgitation is in early stages of development and involves a complex intervention which can not be done in patients with left ventricular leads. Since functional mitral regurgitation is common in low ejection fraction states, we propose a device which can serve for annuloplasty in addition to cardiac resynchronization therapy and simplif...

To better understand the association between mitral regurgitation and secundum atrial septal defect and to clarify the evaluation and management of these patients, the records of 235 adult patients with atrial septal defect were reviewed. Ten patients (4 percent) had significant mitral regurgitation defined by clinical, hemodynamic and angiographic criteria. Three patients required mitral valve...

BACKGROUND To retrospectively evaluate mitral valve abnormality in left atrial myxoma patients by using cardiac computed tomography (CT). MATERIAL AND METHODS Cardiac CT was performed in 56 patients with left atrial myxoma and 50 controls. Tumor and mitral valve characteristics were analyzed. The mitral valve parameters differences were compared between patients with myxoma and controls, myxo...
