Successful treatment of intraoperative rupture of the left ventricle after mitral valve replacement: report of a case and review of the literature.

A case of intraoperative left ventricular rupture following mitral valve replacement, promptly detected and successfully treated, is reported, and the literature concerning 19 other patients successfully treated for this complication is reviewed. Routine inspection of the posterior atrioventricular groove and left ventricular wall is to be recommended after prosthetic mitral valve replacement and before cardiopulmonary bypass is discontinued, to allow recognition of the early signs of ventricular rupture.

Use of prostaglandin E1 in the treatment of sexual impotence after heart transplantation: initial clinical experience.

Many patients report problems of impotence after heart transplantation, which definitely impairs their quality of life. Ten men, with a mean age of 41 years, were evaluated for persistent erection problems after heart transplantation by measurement of nocturnal penile tumescence using a Rigiscan. Three men had a positive response, and their disturbances were therefore considered to have a psychological basis; seven men had a negative or only weakly positive response, and their impotence was attributed to organic causes. To all patients, intracavernous injections of an initial dose of 10 to 20 micrograms of prostaglandin E1 were administered as first-choice treatment. Nine patients obtained a firm, lasting erection 2 to 5 minutes after injection, with no relevant side effects. The patients were then instructed to self-administer the drug before intercourse, and some were able to return to spontaneous sexual activity at various intervals. Intracavernous injection of prostaglandin E1 seems to be an effective treatment of erectile impotence in heart transplant recipients; it is well tolerated with no side effects and considerably improves the patient's quality of life.

Rupture of the posterior wall of the left heart at the atrio-ventricular groove following mitral valve replacement.

The authors report 8 cases of left heart rupture at the insertion of the posterior leaflet of the mitral valve out of 693 mitral valve replacements. Special attention is paid to the anatomy of this area and to the technique of removal of annular calcifications, when present. In reviewing the literature, the authors analyze the cases reported up to now with particular reference to the age of patients, number of valves replaced, size and amount of calcifications, volume of the left ventricular cavity, type and size of the prosthesis employed, supra- or subannular insertion, time between valve application and rupture of the heart, techniques of repair with cardiopulmonary by-pass with a beating or arrested heart. The authors maintain that this dramatic iatrogenic complication can be avoided in most instances with some modifications of the surgical technique which has been adopted in the last 200 mitral valve replacements.

[Cardiac myxoma in the elderly. Clinical study].

Cardiac mixoma in the elderly. A clinical study. The clinical features of 13 cardiac myxomas surgically resected are presented. The mean age at presentation was 68 years. Ten were in the left atrium, 5 near the fossa ovalis, 3 at the base of the atrial septum, 1 at the inferior wall and 1 on the anterior leaflet of mitral valve, 3 were in the right atrium, 1 of these was accompanied with a myxoma at the apex of left ventricle. The ECG and the chest X-ray were normal in 9 and in 8 patients, respectively. In 3 patients, the diagnosis was occasionally made by routine 2-dimensional echocardiography. 5 patients presented with fever of unknown origin, arthralgias, weakness, weight loss. None had intracardiac or extracardiac recurrence in the 73 months follow-up. The presentation with constitutional symptoms only like fever of UO, may mimic collagen and neoplastic diseases, vasculitis, lymphomas: the 2-dimensional echocardiography is mandatory to esclude a cardiac myxoma in the elderly.
