Key result
The left main view (LM-View) fluoroscopic projection visualizes the left main ostium during balloon-expandable TAVR, supporting fluoroscopy for redo-relevant measurements.
Why the study?
Does real-time fluoroscopic assessment using the LM-View and commissural-post method correlate with CT for evaluating left main obstruction risk in redo-TAVR?

Real-time fluoroscopic assessment using the LM-View and commissural-post method provides a valid alternative to CT for evaluating left main obstruction risk during redo-TAVR.
Redo-TAVR feasibility has become central as TAVR extends to younger populations. The left main view (LM-View) fluoroscopic projection has been validated as a deployment view that visualizes the left main (LM) ostium during balloon-expandable (BE) TAVR and allows a more cautious positioning of THV outflow (neo-skirt plane) relative to the LM ostium (coronary-risk plane). A fluoroscopic commissural-post method for THV expansion correlates closely with CT, supporting fluoroscopy for redo-relevant measurements.
