Ruptured Papillary Muscle Report of a Case with Successful Mitral Valve Replacement

Abstract: A case of severe mitral regurgitation secondary to myocardial infarction and rupture of the anterior papillary muscle is presented. Mitral valve replacement resulted in striking improvement.

Ventricular fibrillation induced by an implanted cardiac pacemaker. Report of a successfully treated case.

Abstract: THE introduction of an artificial device or material into the body is attended by problems associated with its failure. This may result in functional or anatomic phenomena requiring special methods of diagnosis and treatment. One such problem found with implanted cardiac pacemakers is that of pacemaker-induced arrhythmias. This paper will detail the successful management of such an arrhythmia and outline certain principles applicable to the emergency handling of this kind of pacemaker failure. Case Report A 69-year-old man (M.G.H. 95097) was first admitted to the hospital in January, 1964. His complaints were of fainting spells, severe dyspnea on exertion and . . .

Surgical correction of congenital intracardiac defects in adult patients.

Abstract: OVER the past seven years approximately 400 patients have been surgically treated at the Massachusetts General Hospital with the assistance of cardiopulmonary bypass. The majority of these patients have been twenty-one or more years of age, including 84 adults who underwent surgical correction of a congenital heart lesion. The present communication concerns this group of 84. Case Material and Results The 84 patients ranged in age from twenty-one to fifty-seven, with an average age of thirty-six years (Table 1). The sex distribution was equal. Nineteen patients had an ostium-secundum type of atrial septal defect, 5 a sinus-venosus atrial . . .

Surgical challenge of aortic valve disease; a follow-up study.

Abstract: The technic of prosthetic replacement of the aortic valve has developed rapidly. Long-term follow-up of 51 hospital survivors of valvuloplasty is presented, showing worthwhile results at three years following operation and, in a very few cases, at four, five or more years. A recent 15 months' experience with 84 valve replacements and 22 valvuloplasties shows an 18 per cent hospital mortality in each group. Results of valve replacement are immeasurably superior to those achieved with incision and debridement in patients with significant aortic regurgitation or heavily calcified valves.
