In our cardiovascular surgery department, interventional occlusion of ruptured aortic sinus aneurysms (ruptured sinus tumors) is routinely performed with satisfactory results. From September 2011 to August 2014, 11 cases were completed, 4 males and 7 females, aged 4 to 37 years. Among them, 2 cases had aortic sinus aneurysm rupture after cardiac surgery, and 5 cases were admitted with symptoms of acute left heart failure, and interventional treatment was performed after active correction of heart failure and improvement of cardiac function. Key points of surgery: 1. determine the location, opening, rupture, and length of aortic sinus aneurysm rupture in order to select a suitable blocker. 2. pay attention to the distance from the right coronary artery, and before blocking and before releasing the blocker, imaging should be performed to clarify that the blocker does not affect the opening of the right coronary artery. 3. pay attention to the contact relationship between the blocker and the aortic valve, and the blocker should not affect the closure of the aortic valve and form friction with the aortic valve. 4. If the aortic sinus aneurysm ruptures into the right atrium, right ventricular membrane or right ventricular crest, the PDA or VSD blocker can be used; if it ruptures into the right ventricular outflow tract, the VSD blocker is preferable to avoid possible medically induced stenosis.
