RESUMEN
Transcatheter aortic valve implantation (TAVI) is the alternative to surgical valve replacement, expanding its indications in the latest guidelines. Multimodal CT (MDCT) is essential in patient selection and detection of complications. Vascular complications are frequent, so it is important to analyse the anatomy of the vessels before the procedure. Regarding annular ruptures and ventricular perforations, the volume and distribution of calcium and the ventricular diameter play an important role. Finally, valve migration is a rare complication that can occur both during and after TAVI. Proper planning of the MDCT procedure reduces the risk of complications and gives the interventional cardiologist security both before and during the procedure.

El implante transcatéter de válvula aórtica, más conocido por su acrónimo en inglés TAVI (Transcatheter Aortic Valve Implantation) es una alternativa al recambio valvular quirúrgico en pacientes inoperables o con alto riesgo quirúrgico. Sin embargo, es una técnica cada vez más utilizada, que no está exenta de complicaciones. La rotura de la raíz aórtica postimplante es una complicación infrecuente, pero letal, y con pocos casos descritos en la bibliografía. La tomografía computarizada multidetector es fundamental antes del procedimiento TAVI para valorar factores predisponentes a la aparición de complicaciones, mientras que su papel posprocedimiento sigue siendo controvertido
Transcatheter aortic valve implantation (TAVI) is an alternative to surgical valve replacement in patients with high surgical risk. Although TAVI is becoming more and more common, it is not without complications. Rupture of the aortic root after implantation is an uncommon, but lethal complication; few cases have been described in the literature. Multidetector computed tomography is fundamental before TAVI to evaluate factors that predispose to complications; however, its role after the procedure is still controversial
