[Surgical treatment of ruptured aneurysm of the sinus Valsalva].

A case of 31-year-old man with ruptured aneurysm of the sinus Valsalva into right atrium originating from noncoronary sinus (Konno's classification type IV) was presented. Patch closure of the defect was carried out through aortotomy followed by resection and direct closure of the aneurysm from right atrium. When placing the patch, pledgetted mattress sutures were passed to the aortic annulus from left ventricle to aorta. It could avoid distortion of aortic valve cusp. Attempting surgical treatment for this type of aneurysm, repair of the defect should be performed through aortotomy to ensure the repair and avoid recurrence of aneurysm, injury to aortic valve and conduction system. Repair from aorta is mandatory, and it is also necessary to open right atrium for the exact inspection of tricuspid valve.
