Abstract

Patients who have complex endocarditis with involvement of both the aortic and mitral valves and intervalvular fibrous skeleton are among the most difficult to treat and still have the highest surgical mortality and morbidity rates. We report one case of aortic and mitral valve replacement with reconstruction of the fibrous skeleton performed in a 55-year-old female patient who had an aortic annular abscess and both the aortic and mitral prosthetic valve endocarditis with destruction of the fibrous skeleton. Previously, she had undergone redo double valve replacement\`, Transesophageal echocardiogram showed the paravalvular defect at the noncoronary aortic sinus and abnormal sinus tract along the fibrous skeleton. Emergent operation was performed due to positive blood cultures of staphylococcus epidermidis and persistent sepsis despite appropriate antibiotic therapy. After aortotomy extended to the roof of left atrium, both prosthetic valves and destroyed fibrous skeleton were completely resected and the aortic annular abscess was debrided and closed with a bovine pericardial patch. Reconstructions of both aortic and mitral annuli and the fibrous skeleton were done by using two separate bovine pericardial patches in triangular shape and mechanical valves were implanted. Postoperatively, adequate antibiotic therapies were continued and the patient was discharged at the postoperative 72 days without evidence of recurrence of endocarditis. Transthoracic echocardiogram of the postoperative 8 months shows no paravalvular leakage or recurrence of endocarditis and the patient has been followed up with no symptom.

대동맥판과 승모판 및 두 판막간 섬유체(fibrous skeleton)를 침범한 복잡 심내막염은 치료가 매우 어려운 질환의 하나로 여전히 술후 사망률과 이환율이 높다. 저자들은 좌측 대동맥판륜 농양 및 섬유체를 파괴한 인공 대동맥판 및 승모판막 심내막염이 동반된 55세 여자 환자에서 섬유체의 재건과 함께 대동맥판 및 승모판 치환을 하였던 예를 보고한다. 환자는 과거에 대동맥판과 승모판을 기계판막으로 두 번 치환술을 받았었다. 심장초음파 검사에서 비관상동의 판막 주위 결손 및 섬유체를 따라 비정상적인 누출 경로가 관탈되었다. 지속적으로 항생제를 투여하여도 혈액에서 staphylococcus epidermidis가 배양되고 지속되는 패혈증 증세를 보여 응급수술을 시행하였다. 대동맥 절개를 좌심방 지붕가지 확장한 다음 두 판막 및 판막간 섬유체를 완전히 절제한 다음 발견된 대동맥판륜 농양은 절제 후 소 심낭 패취를 이용하여 폐쇄하였다. 두 개의 삼각형 모양의 소 심낭 패취를 이용하여 절제된 대동맥 판과 승모판의 각각의 판륜 및 섬유체를 재건한 다음 기계판막을 대치하였다. 술후 지속적인 항생제 투여 후 심내막염 재발 소견이 없어 72일째 퇴원하였다. 술후 8개월에 시행한 심장초음파 검사에서 판막주위 누출이나 심내막염 재발 소견이 없었고 특별한 증세없이 통원치료중이다.
