    Abstract:
    Aneurysms of the sinus of Valsalva are rarely diagnosed before rupture into the cardiac cavities which usually leads to the appearance of a continuous murmur and cardiac failure. In the two cases described, the presenting symptom of the aneurysm was syncope due to cardiac hyperexcitability: ventricular tachycardia in the first and paroxysmal tachyarrhythmia in the second case. The presenting symptoms of unruptured aneurysms of the sinus of Valsalva were analysed. In general, they are: uncontinuous cardiac murmurs: either diastolic murmurs of aortic regurgitation, systolic murmurs of mitral or tricuspid regurgitation, or, as in our first case, of obstruction to right ventricular ejection; arrhythmias: the commonest are conduction defects, which can be syncopal; hyperexcitability (especially ventricular) seems to be very care. Echocardiography is a valuable tool for the diagnosis of sinus of Valsalva aneurysms. The appearances of unruptured aneurysms in our two patients are described. The presence of syncopal cardiac hyperexcitability, possibly associated with one of the preceding auscultatory abnormalities is an indication for echocardiography which may lead to the diagnosis of this condition.
