Antibiotic prophylaxis for infective endocarditis, Medical therapy for heart failure - Angiotensin-converting enzyme (ACE) inhibitors, diuretics, and digoxin, Arrhythmia treatment - Medical treatments such as anti-arrhythmic drugs or radiofrequency ablation of the accessory pathways.
Epidemology: There were two hospital deaths (9%) and the late mortality was 4.5%. The mean followup period was 9 years (range, 1.5 to 13 years) for 19 patients. Significant improvement of VTI(PA) was observed. Analysis of the postoperative deaths demonstrated that all patients were in NYHA class III or IV and had a cardiothoracic ratio of 0.65 or more. A severe reduction in functional capacity seems to be an additional risk factor for mortality beside a cardiothoracic ratio greater than 0.65.
