[Conduction disorders after transcatheter aortic valve implantation: incidence, characteristics, and clinical...

Area of Science:

• Cardiology
• Interventional Cardiology
• Electrophysiology

Background:

• Transcatheter aortic valve implantation (TAVI) is associated with conduction disturbances like left bundle branch block and atrioventricular blocks.
• Patients with pre-existing right bundle branch block face increased risk.
• Permanent pacemaker implantation carries its own short- and long-term complications.

Purpose of the Study:

• To review and define clinical management strategies for conduction disturbances following TAVI.
• To stratify the risk of permanent pacemaker implantation in TAVI patients.
• To provide evidence-based guidance pending randomized trial data.

Main Methods:

• Review of current evidence on conduction disturbances post-TAVI.
• Analysis of risk factors for pacemaker implantation.
• Discussion of electrophysiological testing and ambulatory ECG monitoring utility.

Main Results:

• Conduction disturbances are a known complication of TAVI.
• Risk stratification tools like electrophysiological testing are valuable.
• Management approaches vary, highlighting the need for standardized guidelines.

Conclusions:

• Conduction disorders after TAVI require careful management.
• Pacemaker implantation should be reserved for appropriate indications.
• This review offers evidence-based guidance for clinical decision-making.
