Multimodality Imaging for Planning and Follow-up of Transcatheter Aortic Valve Replacement

Published:April 03, 2017DOI:https://doi.org/10.1016/j.cjca.2017.03.024

      Abstract

      The complementary modalities of Doppler echocardiography and multidetector computed tomography are most frequently used for the planning and follow-up of transcatheter aortic valve replacement (TAVR). TAVR is now a well-established modality in the treatment of high-risk and inoperable patients with symptomatic severe aortic stenosis. Furthermore, recent studies have shown that TAVR is equivalent or superior to surgical aortic valve replacement in patients at intermediate surgical risk. We review the most commonly used imaging modalities and discuss their respective strengths and contributions to optimal patient selection, procedure planning, implementation, and follow-up in TAVR.

      Résumé

      Les modalités complémentaires de l’échocardiographie Doppler et de la tomodensitométrie à multidétecteurs sont le plus souvent utilisées pour la planification et le suivi du remplacement valvulaire aortique par cathéter (RVAC). Le RVAC est une modalité de traitement désormais bien établie dans le traitement des patients atteints d’une sténose aortique symptomatique sévère qui sont exposés à un risque élevé et qui sont inopérables. De plus, des études récentes ont démontré que le RVAC est équivalent ou supérieur à la chirurgie de remplacement valvulaire aortique chez les patients exposés à un risque chirurgical intermédiaire. Nous passons en revue les modalités d’imagerie les plus couramment utilisées et traitons de leurs forces et de leurs contributions respectives à la sélection optimale des patients, à la planification de l’intervention, à la mise en œuvre et au suivi du RVAC.
