    Abstract:
    A 51-year-old male with a two-chambered right ventricle associated with an aneurysm of sinus of Valsalva, who underwent successful surgical repair without ventriculotomy, is reported. Preoperative right ventriculogram revealed that the right ventricle was divided by the anomalous muscle bundle, and the aneurysm of sinus of Valsalva growing from the right coronary sinus protruded just below the pulmonary valve. The right ventricular pressure was 107/10 mmHg and the pressure gradient between the right ventricle and the pulmonary artery was 88 mmHg. Trans-pulmonary arterial resection of the aneurysm of Valsalva sinus was performed and the anomalous muscle bundle was successfully removed through the pulmonary arteriotomy and the right atrial incision. Post-operative right ventricular pressure dropped to 42 mmHg, and there was no stenosis in the right ventricle.
