Insights
A rare complication of transapical aortic valve implantation (TAVI) is delayed coronary artery obstruction. Careful post-procedure evaluation is crucial for early detection and management of this serious TAVI complication.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Transapical aortic valve implantation (TAVI) is a minimally invasive procedure for aortic valve stenosis.
- Complications, though rare, require vigilant monitoring and management.
- Coronary artery obstruction is a potential, albeit infrequent, complication.
Observation:
- A case of left main coronary artery obstruction occurred after a TAVI procedure.
- The obstruction was detected via routine transesophageal echocardiography post-procedure.
- This event highlights a delayed presentation of coronary obstruction.
Findings:
- Subtotal obstruction of the left main coronary artery was diagnosed post-TAVI.
- Prompt coronary stent implantation successfully resolved the myocardial ischemia.
- The findings indicate that coronary obstruction can manifest later, not just during the procedure.
Implications:
- Patients undergoing TAVI require thorough early post-procedure surveillance.
- Delayed coronary artery obstruction is a critical consideration in TAVI patient care.
- This case underscores the importance of comprehensive echocardiographic assessment following TAVI.
Abstract:
We report on an obstruction of the left main coronary artery which occurred after completion of an uneventful transapical aortic valve implantation (TAVI) procedure. This delayed subtotal coronary obstruction was detected by routine final transesophageal echocardiographic examination. Emergency implantation of a coronary stent eliminated myocardial ischemia. This case demonstrated that coronary artery obstruction can occur not only during the TAVI procedure but also some time later. This finding reinforces the idea that these patients must also be carefully evaluated in the early post-procedure period.
