Two Cases of Valsalva Sinus Aneurysm with Rupture into the Right Atrium / 日本心臓血管外科学会雑誌

ABSTRACT

Valsalva sinus aneurysm (VSA) is a rare disease, especially that of Konno classification Type IV. When VSA ruptures, the patient has uncontrollable congestive heart failure because of massive left-right shunt. We encountered two cases with ruptured VSA of the right atrium. Case 1 A 71-years-old man with a ruptured noncoronary VAS complained of dyspnea on effort. He underwent surgical treatment consisting of aneurysm resection and patch closure with Hemashield after medical treatment for congestive heart failure. He progressed well after operation and was discharged on the 14th postoperative day in stable condition. Case 2 A 41-year-old man had heard systolic murmur. We diagnosed VSA rupture with echocardiography. He was symptomless but his left ventricle diastolic diameter was dilatated and Qp/Qs was 2.0 by blood gas sampling. He underwent elective surgical treatment consisting of aneurysm resection and patch closure with Hemashield. He was discharged on the 14th postoperative day in stable condition.
