Is there a role for the left ventricle apical-aortic conduit for acquired aortic stenosis?
GROUND AND AIM OF THE STUDY: Aortic valve replacement (AVR) in patients with a heavily calcified ascending aorta and aortic root, or with conditions that preclude a median sternotomy, poses a formidable challenge. A left ventricle apical-aortic conduit (AAC) is an alternative in these situations. Herein, the authors’ experience with AAC in adult patients with acquired aortic stenosis is reported. METHODS: Between 1995 and 2003, 13 patients (mean age 71 years) underwent AAC for severe symptomatic aortic stenosis (mean valve area 0.65 +/- 0.02 cm2). Indications for AAC were heavily calcified ascending aorta and aortic root (n = 5), patent retrosternal mammary grafts (n = 4), calcified ascending aorta and aortic root plus patent retrosternal mammary graft (n = 1), retrosternal colonic interposition (n = 1) and multiple previous sternotomies (n = 2). Seven patients had previous coronary artery bypass grafting (CABG). The mean preoperative left ventricular ejection fraction was 50 +/- 4%. R
