Description
Summary:Information on surgical outcome of aortic valve replacement (AVR) has not been available in Iceland. We therefore studied the indications, short-term complications and operative mortality in Icelandic patients that underwent AVR with aortic stenosis. This was a retrospective study including all patients that underwent AVR for aortic stenosis at Landspitali between 2002 and 2006, a total of 156 patients (average age 71.7 years, 64.7% males). Short term complications and operative mortality (≤ 30 days) were registered and risk factors analysed with multivariate analysis. The most common symptoms before AVR were dyspnea (86.9%) and angina pectoris (52.6%). Preop. max aortic valve pressure gradient was on average 74 mmHg, the left ventricular ejection fraction 57.2% and EuroSCORE (st) 6.9%. The average operating time was 282 min and concomitant CABG was performed in 55% of the patients and mitral valve surgery in nine. A bioprothesis was implanted in 127 of the patients (81.4%), of which 102 were stentless valves, and a mechanical valve in 29 (18.6%) cases. The mean prosthesis size was 25.6 mm (range 21-29). Atrial fibrillation (78.0%) and acute renal injury (36.0%) were the most common complications and 20 patients (13.0%) developed multiple-organ failure. Twenty-six patients (17.0%) needed reoperation due to bleeding. Median hospital stay was 13 days and operative mortality was 6.4%. The rate of short term complications following AVR was relatively high, including reoperations for bleeding and atrial fibrillation. Operative mortality is twice that of CABG, which is in line with other studies. Inngangur: Ósæðarlokuskipti eru önnur algengasta hjartaaðgerðin á Íslandi og er oftast gerð vegna ósæðarlokuþrengsla.
