Multimodality Imaging to Assess Valvular Heart Disease and Assist - - PowerPoint PPT Presentation
Multimodality Imaging to Assess Valvular Heart Disease and Assist Management Alexander (Sandy) Dick, MD ACC Rockies, 2016 Introduction AVR/TAVI 25-30% AS uncertain - Multimodality Guidelines Appropriate sizing affects outcome
Introduction
- AVR/TAVI
– 25-30% AS uncertain - Multimodality Guidelines – Appropriate sizing affects outcome – Imaging defines and allows novel access
- TMVI
– Nomenclature, standardized measuring
- Structural interventionist as imaging specialist
– Parallel vs collaboration, access to images and analysis tools

PET
Impact CT sizing on TAVR outcomes
- 133 patients underwent TAVR with MDCT
sizing algorithm and 133 without
- PVL > mild
– 5.3% MDCT and 12.8% control (p=0.32)
- Composite in-hospital death, aortic annulus
rupture and PVL > moderate
– 3.8% MDCT and 11.3% control (p=0.020)

Transcaval Access
Lederman et al, CCI, 2015
Transcaval access and closure for transcatheter aortic valve implantation
Transcatheter mitral valve implantation (TMVI)
- Based on TAVI experience much earlier
integration of pre/periprocedural imaging
- Nonplanar annulus; the lack of a circular,
fibrous annular structure; the variability of leaflet and sub- valvular apparatus anatomy and its proximity to the left ventricular
- utflow tract (LVOT)
- TMVI has different requirements than TAVI
– Standardization of approaches and nomenclature
TMVI Anchoring Mechanisms
MA Segmentation
Papillary Muscle Anatomy
Prediction Neo-LVOT
Prediction Angulation
