Ruptured aneurysm of the sinus of Valsalva.
The objective of the present study was to assess the value of imaging techniques in the diagnosis of ruptured aneurysm of sinus of Valsalva (RASV). 38 patients were included in the study. 30 were male and 8 female. Their age ranged from 7 to 55 years (mean 25.8 years). Echocardiographic and doppler studies were done in all cases and 20 patients underwent catheterization and angiography. Two patients were asymptomatic, 20 (53%) had acute onset of symptoms and in the remaining 16 (42%) patients symptoms developed gradually. Twenty two (58%) patients were in NYHA functional class III or IV when first seen. Predominant symptoms were dyspnea (79%), palpitation (55%) and chest pain (52%). A continuous machinery murmur was detected in all the patients with associated thrill in 34 patients. Right coronary sinus (RCS) was the most common sinus involved (89%) followed by the noncoronary sinus (NCS) which was involved in 11% of patients. None of the patients in our series had aneurysm of the left coronary sinus. Twenty eight of the 34 RCS aneurysms ruptured into the right ventricular outflow tract (RVOT), 4 into right ventricular cavity (RVC), one into right atrium (RA) and one dissected into the ventricular septum and subsequently ruptured into the left ventricle. Of the 4 NCS aneurysms, 2 ruptured into RVC, one into RA and one into both the RA and RVC. Associated ventricular septal defect (VSD) was found in 10 (26%) patients and all of these patients had RCS aneurysm that ruptured into the RVOT. Aortic regurgitation (AR) was detected in 16 (42%) cases. Discrete subaortic stenosis was detected in one patient who also had associated VSD and AR. Vegetation of the aortic valve was detected in one patient who had RCS aneurysm. Twelve patients (11 male and one female) underwent surgical correction, 10 with and 2 without prior catheterization. Localization of the involved sinus, site of rupture and associated cardiac lesions by echocardiography and doppler study were found accurate at surgery and/or angiography in 22 cases of our series. Imaging techniques, thus appeared to be reliable tools for the diagnosis of RASV.
