Key result
A potential risk of sinus of Valsalva sequestration for future redo TAVR was identified in 52.1% of patients with balloon-expandable valves and 71.3% with self-expanding valves.
Why the study?
What is the CT-predicted risk of sinus of Valsalva sequestration for future redo TAVR following initial TAVR in an Asian patient population?
What is the CT-predicted risk of sinus of Valsalva sequestration for future redo TAVR following initial TAVR in an Asian patient population?
A substantial proportion of patients undergoing index TAVR have anatomies predicting a high risk of coronary obstruction if redo TAVR becomes necessary, highlighting the need to optimize index valve selection and implantation depth.

Elbadawi et al. (2023) conducted an editorial in Prior transcatheter aortic valve replacement (TAVR) (n=1,122). Balloon-expandable valves (BEVs) or self-expanding valves (SEVs) was evaluated on Potential risk of sinus of Valsalva (SOV) sequestration / coronary occlusion for future redo TAVR (defined as TAVR commissure level above STJ and THV-to-STJ distance <2.0 mm). A potential risk of sinus of Valsalva sequestration for future redo TAVR was identified in 52.1% of patients with balloon-expandable valves and 71.3% with self-expanding valves.
