Key result
Emergent PCI via snorkel technique successfully treats delayed LMCA obstruction 6 hours after TAVR.
Why the study?
There is no consensus on the optimal approach to investigation and revascularization in patients with delayed coronary obstruction after TAVR, especially in those without traditional risk factors.
Case Report (n=1)
Highlights a rare case of delayed coronary obstruction post-TAVR in a patient without traditional risk factors, successfully managed with emergent revascularization.
Raises awareness for delayed coronary obstruction after TAVR; hypothesis-generating for snorkel PCI in such emergencies.
We present a rare case of delayed coronary artery obstruction following a transcatheter aortic valve replacement (TAVR). Interestingly, the patient did not meet the criteria for traditionally recognized risk factors for delayed coronary obstruction. This case piques interest as to whether the severity of calcification on aortic valve leaflets plays any role in coronary obstruction post transcatheter aortic valve replacement. There is no consensus as to the optimal approach to investigation and revascularization in patients with delayed coronary obstruction. We report a case with successful emergent revascularization of the left main coronary artery following transcatheter aortic valve replacement.

Limani et al. (2022) conducted a case report in Severe bicuspid aortic valve stenosis and delayed coronary obstruction (n=1). Transcatheter aortic valve replacement (TAVR) and emergent PCI was evaluated on Successful emergent revascularization. Emergent percutaneous coronary intervention using the snorkel technique successfully treated a rare case of delayed left main coronary artery obstruction 6 hours after TAVR.
