Abstract/OtherAbstract:
BACKGROUND: Paravalvular aortic regurgitation after transcatheter aortic valve implantation is associated with a hemodynamic deterioration and a poor outcome. We aim to determine the early hemodynamic effect of paravalvular aortic regurgitation in relation with the change in the left ventricle filling pattern and to assess their clinical outcome.
MATERIAL AND METHODS: 82 consecutive patients referred for transcatheter aortic valve implantation were included. Patients were classified according to the change in the left ventricular filling pattern and significant paravalvular aortic regurgitation (grade ≥2) was reported. Follow-up and incidence of death and hospitalization for heart failure were reported.
RESULTS: 16 patients (19.5%) presented a worsening of left ventricular filling pattern. The incidence of significant paravalvular aortic regurgitation was higher in the group with a worsening of left ventricular filling pattern (56.3% vs. 19.7%;p=0.009). In the multivariate analysis, the only variable significantly associated with the worsening of left ventricular filling pattern was the significant paravalvular aortic regurgitation (OR 4.84; 95%CI 1.23-19.1;p=0.024). During the follow-up (642.5 days) there was a higher incidence of the end-point of death or hospitalization for heart failure in the group with a worsening of left ventricular filling pattern (62.5 vs. 31.8%;p=0.042) and a lower event-free survival rate (long rank test=0.013).
CONCLUSIONS: The presence of a significant paravalvular aortic regurgitation is associated with a worsening in parameters of diastolic function. This finding should alert the cardiologist as patients with a worsening of left ventricular filling pattern present a higher incidence of paravalvular aortic regurgitation and a less favorable outcome.
