title: Unruptured congenital aneurysm of the sinus of Valsalva presenting with pulmonary stenosis.
abstract: Congenital aneurysm of the sinus of Valsalva is a rare cardiovascular anomaly. It is usually silent until rupture occurs. The natural history of unruptured aneurysm of the sinus of Valsalva is still not clear, and the therapeutic strategy is uncertain. Here we reported a case of unruptured aneurysm of the sinus of Valsalva which was correctly diagnosed before invasive diagnostic procedures. A 30-year-old female noted mild palpitation and dyspnea for 1 month. Physically, a grade 3/6 systolic ejection murmur at upper left sternal border was detected. Echocardiography revealed dilatation and irregular protrusion of the right sinus of Valsalva encroaching on right ventricular outflow tract to cause obstruction. With these findings, unruptured aneurysm of the sinus of Valsalva with pulmonary stenosis was diagnosed. Cardiac catheterization and angiography confirmed the diagnosis. The aneurysm was repaired with a Dacron patch with good results. It is concluded that sinus of Valsalva aneurysm can be diagnosed by echocardiography before its rupture so as to render a proper management for this potentially life-threatening anomaly.
