[Multiplicity of clinical symptoms and manifestations of unruptured aneurysms of the sinus of Valsalva--3 case reports].

Sinus Valsalva aneurysms belong to the less common congenital or acquired structural cardiac anomalies. However, in patients with known cardiac anomalies and uncertain or uncharacteristic cardiac symptoms the existence of a sinus Valsalva aneurysm must be taken into consideration. A sinus Valsalva aneurysm can be clinically silent as in the case of the 56-year-old patient with an accompanying bacterial endocarditis. An increasing aortic regurgitation after dilatation of a coarctation of the aorta can also proceed with an ecstasy of the ascending aorta and an aneurysm of the sinus Valsalva (case 2). Furthermore, a rapid dilatation of a non-ruptured sinus Valsalva aneurysm can cause a severe compression of coronary arteries with subsequent myocardial infarction, as in the 27-year-old patient with congenital aortic stenosis and acute endocarditis in case 3.
