Rupture of Aortic Sinus Aneurysms Diagnosed by Left Ventricular Opacification.

Rupture of aortic sinus aneurysms is a rare cardiac malformation that is commonly observed in the right coronary sinus but is rarely observed in the noncoronary sinus. Here, we report a case of aneurysm of the aortic sinus that ruptured into the left ventricular outflow tract and was diagnosed with left ventricular opacification. Left heart echocardiography can clearly demonstrate the structure of the heart and is one of the important diagnostic methods for diagnosing ruptured aortic sinus aneurysms. This observes the perfusion sequence of blood flow to clearly reveal the source, direction, and location of the ruptured aortic sinus aneurysm.
