An Unusual Case of Dissecting Aneurysms Involving Both Coronary Sinuses of Valsalva

A 16-year-old boy with a progressive history of dyspnea and palpitations was diagnosed to have rupture of the right and left coronary sinuses on transthoracic echocardiography. The right coronary sinus had ruptured and dissected into the interventricular septum from its base up to the left ventricular apex and all around the lateral wall of the left ventricle up to the base of the papillary muscles. The left coronary sinus was also ruptured, and the rupture was contained by a false aneurysm that dissected into the roof of the left atrium from the aortomitral intervalvular fibrosa. The involvement of multiple coronary sinuses is extremely rare.
