Ruptured sinus of Valsalva aneurysm
Updates to Case Attributes
Ruptured Valsalva sinus aneurysm:.
Sinus of Valsalva aneurysm appears as a saccular outpouching from the sinus of Valsalva. When it ruptures, it most commonly ruptures into the right ventricle, followed by the right atrium. The aorto-cardiac shunt (left to right shunt) can lead to insidious heart failure.
Extracardiac rupture is rare and can lead to cardiac tamponade, which carries a higher mortality rate. The treatment option is cardiopulmonary bypass surgery.

Updates to Study Attributes
Axial stack images ofECG-gated cardiac CT shows that the right posterior (noncoronary) sinus of Valsalva has ruptured into the right atrium.
Updates to Study Attributes
Orthogonal planes of gated cardiac CTA demonstrate a right coronary sinus of Valsalva sinus aneurysm that has ruptured into the right atrium (white arrow). A jet of contrast through the defect into the right atrium is also seen (black arrow).
