A44-year-old woman received pacemaker implantation (PMI) at age 43 because of complete atrioventricular block. One year after PMI, she suffered palpitations and fainting. Cardiac examination revealed aneurysm of the sinus of Valsalva dissecting into the interventricular septum and severe aortic regurgitation. Patch closure of the aneurysm of the sinus of Valsalva and aortic valve replacement were carried out under complete cardiopulmonary bypass. The endocardial leads were removed and epicardial leads were implanted for the pacemaker. This is a very rare case. The first symptom could have developed from conduction disturbance, such a complete atrioventricular block. The patch closure of the aneurysm and aortic valve replacement was considered effective for this disease.
