Abstract:
Right ventricular outflow tract (RVOT) obstruction caused by sinus of Valsalva aneurysm is a rare observation. We describe a successful case of valve-sparing root replacement using reimplantation technique for RVOT obstruction by a large right coronary sinus of Valsalva aneurysm in a 76-year-old man. In the pathological examination, the elastic fibers of the medial layer were defective not only in the wall of the aneurysmal Valsalva sinus but also in the remaining two sinus walls. Our experience illustrated that valve-sparing root replacement can be an effective procedure in such a case.
