The results of investigation in 5 children with congenital deformities of the mitral valve region characteristic of the 'parachute mitral valve complex' were reviewed. Three patients had parachute mitral valve, i had supravalvar mitral ring, and i had both these lesions. Associated anomalies included ventricular septal defect, double outlet right ventricle, subaortic stenosis, bicuspid aortic v...

OBJECTIVE This study evaluated the effects of a new method of mitral valve replacement on left ventricular (LV) remodeling and heart failure functional class. METHODS Eight patients (6 men) with severe mitral regurgitation from end-stage dilated cardiomyopathy underwent surgery. Five patients were in functional class (FC) IV, 2 were in FC III and 1 was in FC III/IV. Age ranged from 33 to 63 y...

Harvey (1968) used the term "wreck.ing ball" to describe the movements of a calcified pedunculated right atrial myxoma, likening it to the swinging iron ball suspended from a crane used for demolishing buildings. In the patient he described the tricuspid valve had been almost completely destroyed by the movemen,ts of the tumour. Similar patients with incompetent tricuspid valves damaged by calc...

While prosthetic valves are acceptable in the subcoronary position, their use for mitral or tricuspid replacement is less satisfactory. Introduced by Ross in I962, aortic homografts for aortic valve replacement have found a definite place in the modem surgical armamentarium and have paved the way towards heart valve grafting. Naturally, for an improved mitral valve substitute, attention was dir...

BACKGROUND Recently, infant cases of acute heart failure attributable to rupture of the mitral chordae tendineae have been reported. However, little is known about the pathogenesis and clinical course of this condition. METHODS AND RESULTS Ninety-five children with rupture of mitral chordae tendineae were identified in nationwide surveys of Japan diagnosed from 1995 to 2013. The clinical mani...

RUPTURE of the chordae tendineae is an uncommon event that may lead to sudden mitral regurgitation, the severity of which generally depends on the number and location of the chordae involved.1 It has been reported to occur with active bacterial or rheumatic endocarditis, in association with healed rheumatic valvulitis, following healed bacterial endocarditis or trauma, or "spontaneously" in hea...

It is assumed that the human heart is almost identical to domestic mammalian species, but with limited literature to support this. One such area that has been underinvestigated is that of the subvalvular apparatus level. The authors set out to examine the morphology of the subvalvular apparatus of the mammalian atrioventricular valves through gross dissection and microscopic analysis in a small...

Open heart surgery has been performed at the Massachusetts General Hospital in 13 patients less than 6 months after the initiation of treatment for acute or subacute bacterial endocarditis. The endocarditis involved the aortic valve in 12 cases and a mitral valve prosthesis in the other. In two patients there was concomitant rupture of chordae tendineae of the mitral valve. One patient received...

OBJECTIVE This study aimed at evaluating results of mitral valve replacement using a new technique of complete chordae tendineae adjustment for left ventricular remodeling. METHODS Twenty end-stage idiopathic dilated cardiomyopathy patients with severe functional mitral valve regurgitation underwent mitral valve replacement. Seventeen (85%) were in functional class IV. Both anterior and poste...

INTRODUCTION Degenerative mitral regurgitation is currently the most frequent indication for mitral valve repair. AIM To visualize and assess the mid-term results of mitral valve repair with neochordae implantation, using computed tomography angiography (CTA) imaging. MATERIAL AND METHODS The CTA with ECG gating and without modulation was applied in 10 patients to assess the results of a mi...
