337 Elderly Patient with Single Right Coronary Artery and Congenital Absence of Left Coronary Artery

Abstract

declined between each age bracket (p,0.015), with LA contractile strain increasing in groups 'b' and 'c' vs group 'a' (p=0.006 and p,0.001, respectively). Conclusion: LA conduit strain is altered early with a compensatory increase in LA contractile strain, whilst LA reservoir strain shows progressive reduction with increasing age. These phasic functional changes are reflected by an early increase in LA PreP volume and subsequent increase in LA min .
