The Effect Of Calcium Score On Aortic Regurgitation Post Transcatheter Aortic Valve Replacement

Abstract

Introduction: As transcatheter aortic valve replacements (TAVR) becomes more common in lower risk populations, the importance of even mild post-procedural paravalvular aortic regurgitation (AR) becomes more important. A very high Agatson calcium score (CS) of the aortic valve has been shown to be an independent prognostic factor for ≥ moderate aortic regurgitation post TAVR, however, the predictive value of CS for mild AR is not known. Furthermore, the evidence mainly refers to older TAVR valve models; new TAVR valve models have much lower rates of AR, and the evidence of calcium scoring to predict AR in these devices is limited. Our aim was to study the relationship of valve calcium and paravalvular AR in the current generation of devices.
