Sinus of Valsalva aneurysm is a rare anomaly with a higher incidence in Eastern than Western populations. Recent improvements in diagnostic techniques have resulted in more patients undergoing surgical repair. Uncorrected, the intracardiac shunts and frequently associated cardiac lesions cause a preventable deterioration in heart function. We retrospectively analyzed the data of 33 patients who underwent repair of ruptured sinus of Valsalva aneurysm from May 2000 to January 2010. The aneurysms originated from the right coronary sinus in 24 patients and from the noncoronary sinus in 9, and ruptured into the right ventricle in 21, right atrium in 10, and left ventricle in 2. Operative procedures included simple plication (1), patch repair (32), and aortic valve replacement (10). There were 3 early deaths. The 30 survivors were followed up for 5.4 ± 2.6 years; all had an improvement in functional class, with superior results in those with no aortic regurgitation. Surgical treatment of ruptured sinus of Valsalva aneurysm has an acceptably low operative risk and good long-term symptom-freedom survival. An early aggressive approach is recommended to prevent worsening symptoms and more extensive disease.

The aim of this study was to investigate a rare subset of adult patients with double-chambered right ventricle, pertaining to clinical presentation, rhythm disturbances, surgical approach, and results of surgical repair. A retrospective review of our records revealed that 14 adults had undergone surgical repair of double-chambered right ventricle from 1990 to 2010. Their median age was 25.5 years, and their median weight was 50 kg. Patients presented with various symptoms, the most common being dyspnea on exertion. The mean systolic pressure gradient across the obstruction was 69.8 ± 23.1mm Hg. The most common associated anomaly was ventricular septal defect. Significant rhythm disturbances were present in 4 patients. Transatrial repair was undertaken in 5 patients, a combined transatrial and transpulmonary approach was used in 4, and a right ventriculotomy in 5. There was no mortality at a median follow-up of 5.1 years. A mild right ventricular outflow tract gradient was noted in 2 patients. Medical management was required for rhythm disturbances in 2 patients. Double-chambered right ventricle can present in adulthood, often with vague symptoms. The midterm results of surgical correction are satisfactory. Long-term follow-up is necessary to detect late arrhythmias.
