Summary
Bundle branch reentrant ventricular tachycardia (BBRT) can occur after TAVI. This case shows some BBRT instances are transient, resolving without permanent ablation or pacing.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Macro-re-entrant ventricular tachycardia (VT) involving the cardiac conduction system is a recognized complication.
- Transcatheter aortic valve implantation (TAVI) procedures carry risks, including cardiac arrhythmias.
- Bundle branch reentrant ventricular tachycardia (BBRT) is a specific type of VT involving the right and left bundle branches and ventricular septum.
Purpose of the Study:
- To highlight BBRT in the differential diagnosis for patients undergoing TAVI.
- To present a case demonstrating the transient nature of post-TAVI BBRT.
- To emphasize that some cases of post-TAVI BBRT may resolve spontaneously.
Main Methods:
- Case report presentation.
- Review of patient history and procedural data.
- Electrocardiographic analysis of ventricular tachycardia morphology and resolution.
Main Results:
- The patient developed BBRT following a TAVI procedure.
- The BBRT was observed to be transient.
- Resolution occurred without the need for permanent intervention such as ablation or pacing.
Conclusions:
- BBRT should be considered in the differential diagnosis of arrhythmias post-TAVI.
- Transient BBRT can occur after TAVI and may resolve spontaneously.
- Recognizing transient BBRT can prevent unnecessary interventions like permanent pacing or CRT.
