The results of surgery in 21 patients with I.H.S.S. are reported. Dyspnea, angina pectoris and syncope were the most common symptoms in decreasing frequency. Before the operation, 5 patients were in New York Heart Association's functional class II, 10 in class III and 6 in class IV. The mean resting peak systolic pressure gradient was 66 mm Hg in 20 patients and mean left ventricular end-diastolic pressure was 14 mm Hg in 19 patients. The ventriculoseptomyectomy accomplished through a transaortic approach is the procedure of choice. The operative mortality rate was 14% (3 of 21 patients). There were 2 late deaths from congestive heart failure. Any sudden death did not occur. The remaining 16 patients have been followed up for a mean of 75 months (range 12 months to 11 years), 11 patients are in functional class I, 4 in class II and 1 in class III. Complete left-bundle-branch block occurred in 3 patients. Our study with a long post-operative follow-up period, documents that surgery results in good to excellent alleviation of symptoms in survivors. The elevated pre-operative left ventricular end-diastolic pressure has a significantly poor prognosis. We currently recommend surgery for the symptomatic patients who have not responded to medical therapy, not late in the symptomatic course of the disease.

A case of candida albicans endocarditis 3 years after an aortic valve replacement. Successful combined medical and surgical therapy.

The authors report a case of candida albicans endocarditis occurring 3 years after aortic valve replacement and bacterial endocarditis. They may attempt to the difficulty of the diagnosis, the successful combined surgical and medical treatment, the duration and the follow-up of the therapy and finally the aspect of the side effects of the used antifungal drugs.

Surgical repair of coarctation of the aorta in infants under one year of age. Long-term results in 146 patients comparing subclavian flap angioplasty and modified end-to-end anastomosis.

Between July 1976 and February 1991, 146 consecutive infants underwent surgical repair of coarctation of the aorta. Age at operation varied from 2 days to 11 months (median 1 month). Ninety-two (63%) were less than 2 months. Isolated coarctation was present in 65 patients (group 1), associated ventricular septal defect in 49 patients (group 2) and complex anomalies in 32 patients (group 3). The majority (65%) were in a critical condition and 45 patients (31%) were artificially ventilated. Subclavian flap angioplasty was performed in 39 patients and resection and end to end anastomosis in 107 patients. Neither hospital mortality was significantly different between subclavian flap angioplasty (15%) and end-to-end anastomosis (18%) nor was the postoperative hypertension. Actuarial survival at 10 years were 100% for group 1, 94% for group 2, and 62% for group 3. Seventeen patients had recurrent coarctation. No significant difference was found in terms of types of repair or age at operation. As no major advantage in terms of mortality and morbidity to either technique was found, we recommend resection and end-to-end anastomosis. This technique not only relieves the obstruction whatever the level is but also eliminates the ductal tissue, preserves the subclavian artery and avoids the use of prosthetic material.

Aortic valve replacement thirty-one months after orthotopic heart transplantation.

Aortic valve replacement with a St. Jude prosthesis was performed 31 months after orthotopic heart transplantation in a 28-year-old male patient with Steinert's disease and idiopathic cardiomyopathy. The donor heart was reported as being normal by the cardiologist of the referring hospital. During implantation, a bicuspid aortic valve was noted, and early after the operation mild aortic regurgitation became apparent. Aortic incompetence advanced to a severe degree within 2 years after transplantation. Valve replacement, instead of retransplantation, was undertaken after careful consideration of the advantages and disadvantages of the therapeutic choice. This case report demonstrates the feasibility of valve replacement after heart transplantation and emphasizes the need for careful evaluation of potential donor hearts before harvesting.

Surgical treatment of subvalvular aortic stenosis. Long-term results.

From 1966 till May 1988, 53 patients underwent surgery for fixed subaortic stenosis. Subvalvular obstruction was isolated in 27 patients (Group I) and associated with aortic valve lesions in 26 (Group II). A membranous stricture was documented in 5 patients and a fibromuscular ring in 48. Excision of the ring and myectomy were performed in all patients, and an associated aortic valve replacement or reconstruction in 7 and 4 patients respectively. There were no hospital deaths. Follow-up evaluation in 50 patients ranged from 6 months to 22 years. Eight patients had to be reoperated upon (1 from group I, 7 from group II): aorto-ventriculoplasty was performed in 3, aortic valve replacement with redo myectomy in 3 and mitro-aortic valve replacement in 2. One of them had 2 reoperations. Functional status at the time of the last outpatient visit was most satisfactory. Continued evaluation remains necessary as obstruction may reappear despite the absence of symptoms.
