“…Some recommend routine prosthetic valve replace-ment1517 of the mitral valve in all such cases, while others do this only in ruptured chordae of the anterior leaflet.19 Still others do plastic repair of the leaflets and annuloplasty for this oondition.5' 6,8,[11][12][13][14] The major alternative to plastic repair is valve replacement. The data available dealing with long-term results after mitral valve replacement have mainly concerned patients suffering from rheumatic valvular heart disease (data not exclusively for ruptured chordae), and therefore are not necessarily comparable to ours.…”

Repair of Mitral Incompetence Secondary to Ruptured Chordae Tendineae

Twenty-two patients with ruptured chordae tendineae are presented. Etiology was rheumatic heart disease in seven patients, bacterial endocarditis in four patients, both rheumatic heart disease and endocarditis in two patients, trauma in one patient, and aortic regurgitation in one patient. Exact cause of rupture was unknown in seven patients. Plastic repair of the leaflet and/or posteromedial annuloplasty was done in all the patients. In two patients the annuloplasty broke down soon after the operation and necessitated valve replacement. There was one hospital death. One patient died two years after operation probably because of cerebral embolism; a large thrombus was found in the left atrium at autopsy. All survivors have been followed for 7 months to 8 years and, except for two, are either working full-time or leading an active life.In ruptured chordae early and five-year results after repair of the leaflet and/or posteromedial annuloplasty are very good irrespective of the left atrial enlargement and "V" wave size. Results were better in the rheumatic group than in the nonrheumatic group. In our opinion this method of treatment is superior to prosthetic valve replacement for this condition, except if the annulus is thin and attenuated.

“…In our first patient with constrictive pericarditis and aortic and mitral regurgitation, the right atrial 'v' waves were the result of the interatrial septum bulging into the right atrium because of the massive mitral incompetence and the constrictive pericardium preventing the right atrium from absorbing this pulsation. The illusion of tricuspid regurgitation was augmented in this patient by the parasternal radiation of the pansystolic murmur because the mitral regurgitation was due to chordal rupture (Brown et al, 1968).…”

Brown, A. H., and Braimbridge, M. V. (1973). Thorax, 28,[495][496][497]. Spurious tricuspid regurgitation: Three conditions mimicking tricuspid regurgitation diagnosed at operation. The diagnosis of tricuspid incompetence is difficult. Three patients are described in whom the diagnosis of tricuspid regurgitation was made but disproved by the findings at surgery. The first patient had aortic regurgitation, mitral regurgitation from chordal rupture, and constrictive pericarditis; the right atrium was compressed between the pulsating left atrium and the tight pericardium. The chordal rupture caused the mitral murmur to radiate parasternally. The second patient had severe mitral and aortic regurgitation and an interatrial septal defect with transmission of the left-sided 'v' waves to the right atrium. The third patient had an iatrogenic Gerbode defect from a previously repaired ostium primum atrial septal defect. Intracardiac phonocardiography failed to distinguish the anatomical situation from tricuspid regurgitation. The best assessment of tricuspid valvular disease is still that of the surgeon at operation.

“…The choice of valve was left to the individual surgeon. Forty six (46%) patients had a Starr-Edwards 6120 prosthesis, 27 (27%) a Bjork-Shiley tilting disc valve, 18 (18%) a Carpentier-Edwards porcine xenograft, nine (9%) an aortic homograft, and one an Omniscience tilting disc valve. The prostheses were inserted with interrupted over and over 2-0 Ethiflex sutures.…”

suMMARY During the period 1970-81, 183 patients underwent mitral valve surgery for chordal rupture. Of these, 82 (45%) patients were treated by mitral valve repair and 101 (55%) by mitral valve replacement. Mean age at surgery was 57 years. The early mortality was nine of 183 (4.9%) patients, of whom five had undergone replacement and four repair. During the follow up period (mean 3-6 years, range 0-8-12-2 years) a further 27 patients died; 23 of these had undergone mitral valve replacement and four mitral valve repair. Cerebrovascular events accounted for 35% of the deaths after mitral valve replacement and none of those after mitral valve repair. In 11 patients repair was technically unsatisfactory, and mitral valve replacement was undertaken at the same operation; a further five patients required late replacement (mean 1.4 years) for pronounced mitral regurgitation. Actuarial curves predict a six year survival of 68+5 7% (mean+ SD) for all patients after mitral valve replacement compared with 88+6*9% (mean±+SD) after repair (p<001). Actuarial survival curves favour mitral valve repair as the procedure choice for chordal rupture, and in isolated posterior cusp repair breakdown of the repair is a rare occurrence.
