Key result
TAVI causes rare type B aortic dissections that are harder to detect than type A.
Why the study?
Acute type B aortic dissection is a rare complication of TAVI that is more difficult to detect during the procedure than acute type A aortic dissection.
Iatrogenic acute type B aortic dissection is a rare complication of TAVI that can be detected early with transesophageal echocardiography and may be successfully managed conservatively.
May warrant heightened post-TAVI monitoring for type B dissection; leaves open prospective validation of detection strategies.
Objective: As the number of transcatheter aortic valve implantation (TAVI) procedures increases, specific complications, including aortic dissection, have been reported. Acute type B aortic dissection (ATBAD) is rare but more difficult to detect during TAVI compared to acute type A aortic dissection (ATAAD). This study presents our experience with iatrogenic ATBAD during TAVI.

Sugiyama et al. (2026) studied this question. Transcatheter aortic valve implantation can be complicated by iatrogenic acute type B aortic dissection, which is rare but more difficult to detect than acute type A aortic dissection.
