Abstract
Background: The presence of mitral annular calcification (MAC) affects prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). MAC frequently coexists with calcifications of mitro-aortic continuity (CMAC). Aims: We aimed at qualitative and semi-quantitative analysis of calcifications of the mitral complex - MAC and CMAC in multi-slice computed tomography, in order to assess their impact on the occurrence and dynamics of mitral regurgitation (MR) following TAVI. Methods: The study group consisted of 94 patients (mean [SD] age was 79.9 [8.02] years; 67.1% female). Agatston scale - Calcium Score was used for quantitative analysis. MAC and CMAC were also assessed semi-quantitatively as either non-severe or severe. MR following TAVI was defined as unchanged, improved or worsened by at least one degree. Results: Patients with MAC (59.6%) had higher mean aortic gradients (P= 0.02) and smaller left ventricular diastolic diameter (P = 0.002). Patients with CMAC (48.9%) had higher Calcium Score aortic valve (P= 0.006). After TAVI MR improved in 17 (18.1%) patients and worsened in 7 (7.5%) patients. In multivariable logistic regression analysis MR worsening was associated with higher CMAC (OR, 1.092; 95% Cl, 1.006-1.185; P= 0.03), as well as bicuspid aortic valve (OR, 6.348; 95% CI, 1.048-38.436; P= 0.04). Conclusions: CMAC was associated with MR worsening following TAVI.This is of relevance in procedural planning in patients with severe aortic stenosis (AS) and coexisting MR in whom arguments for and against surgical repair of concomitant mitral insufficiency are considered.Keywords
