Ruptured sinus of Valsalva aneurysm complicated by myocardial ischemia: pathogenetic mechanisms.

Significant left-to-right shunt in combination with severe aortic regurgitation (AR) accelerates the development of symptoms after rupture of congenital sinus of Valsalva aneurysm (SVA) in spite of intact coronary arteries. We depict a rare description of a situation where acute coronary syndrome was the first manifestation of such an occurrence. We believe that the progress of the myocardial ischemia after ruptured SVA depends on the severity of AR and the quantity of the left-to-right shunt. Prompt recognition and surgical repair are indicated to prevent complications of myocardial infarction.
