Seven patients have been described who developed a third heart sound in association with a paravalvar leak around a Starr-Edwards mitral valve prosthesis. These patients had all had the mitral valve cusps, chordae tendineae, and part of the papillary muscles excised. The presence of a third heart sound in them supports the concept of Potain (I900) that the third heart sound arises by vibrations...

Repair of mitral valve (MV) leaflet prolapse using chordal replacement is an established procedure in open heart surgery for the treatment of mitral regurgitation (MR). The technique has proven high reproducibility and excellent longterm outcomes for posterior leaflet prolaspe, with freedom from valve-related reoperation of 95%.1,2 Striving toward a lessinvasive treatment for structural heart d...

BACKGROUND The use of artificial chords for the replacement of diseased mitral valve chordae and the correction of anterior and posterior leaflet prolapse is well described, although it is infrequently applied because of technical challenges. METHODS A simplified approach to attaching the new chords to a single papillary muscle base within the left ventricle has been reported, and we present ...

Direct insertion of the anterior papillary muscle (DPM) into the mitral valve is uncommon. During the routine dissection of an adult female, a DPM into the mitral valve with abnormal chordae tendinae was observed. This abnormal papillary muscle was measured as 28.0 mm in length from myocardial to insertion, 14.8 mm in width, and 7.0 mm in depth. The embryology, symptoms, associated cardiac dise...

A 32-year-old male patient was admitted to our clinic with complaints of exertional chest pain and shortness of breath. His blood pressure was 120/70 mmHg and his heart rate was 80 bpm. In the physical examination, Grade II/IV mid-diastolic murmur was noted at the cardiac apex with a harsh S1. His electrocardiogram was within normal limits. In transthoracic echocardiography, a mobile, heterogen...

A spectrum of mitral valve disease was noted in 71 per cent of 163 specimens with transposition of the great arteries. At one end of the spectrum were hearts with normal mitral valve, except that the free margin of the anterior leaflet was shortened; at the other end were specimens with underdevelopment of the space between or behind the papillary muscles of the left ventricle. In additional ...

M itral valve leaflets consist of thin, pliable, fibrous material. The two leaflets—anterior and posterior—open by unfolding against the ventricular wall and close by apposition when the pressure in the left ventricle becomes greater than that in the left atrium. Mitral stenosis occurs when the mitral valve leaflets become stiffened, calcified, and unable to open completely during diastole. Thi...

Eighteen percent of heart specimens with isolated ventricular septal defect also had a floppy mitral valve. There was no statistical difference in the incidence of floppy mitral valve in the three age groups considered (less than 1 year, 1 to 16 years and 17 to 91 years). In no patient was a floppy mitral valve considered to be the cause of death. Complications of floppy mitral valve (ruptured ...

Rupture of chordae tendineae resulting in acute mitral regurgitation has previously been described following rheumatic fever, subacute bacterial endocarditis, blunt chest trauma, and in Marfan's syndrome. Chordae may rupture spontaneously in older patients, producing a characteristic clinical syndrome, but such 'idiopathic' rupture is exceptional before the age of 50. This paper reports the occ...
