0036 : Prognostic value of concomitant aortic regurgitation in patients operated for severe aortic stenosis

Abstract

The aim of this study was to evaluate the prognostic value of concomitant aortic regurgitation (AR) in patients operated for severe aortic stenosis (AS) by examining the impact of presence and severity of concomitant AR in patients operated for severe AS on short-term outcome. Retrospective study including 37 consecutive patients operated due to severe AS. Patients were divided in two groups, G1: AS group (n=15) and G2: AS + AR (n=22). All patients had a transthoracic echography a week and 6 months after cardiac surgery. Patients mean age was 59,08 with older patients in group 66,16±6,4 vs 54,27±16,3 (p=0,012). 59,5% of the patients were males. Dyspnoea was the predominating symptom (74%) with 40% in stage II and 26% in stage III of NYHA. Coronary artery disease was more frequent in G1 (33% vs 14%; p=0,079, NS). Pre-operative echocardiography showed no difference between the two groups for left ventricular ejection, LV hypertrophy, mean aortic gradients, aortic area and pulmonary pressure. However mean LV diameters were greater in G2 with a mean LV end diastolic diameter (LVEDD) à 58,95±8,4 mm vs 51,2±8,19 mm (p=0,018) and LV end systolic diameter (LVESD) à 39,6±10,5 mm vs 33,2±8,79 mm (p=0,049). Immediate and short-term echocardiographic follow-up showed no difference between the 2 groups. Only LV diameters were greater in G2 avec un LVEDD 59,1 mm vs 51 mm (p=0,03) et LVESD 40,3 mm vs 33,2 mm (p=0,02) à 1 week and LVEDD at 58, 8±9,9 mm vs 50,7±8,19 mm (p=0,032) and LVESD à 40,1±9,7 mm vs 32,8±12 mm (p=0,024) at 6 months. Our data indicate that the preoperative presence of concomitant AR was associated with greater LV diameters. The author hereby declares no conflict of interest
