Long-Term Ventricular Pacing Dependency and Pacemaker Implantation Predictors after Transc

340 patients who underwent transcatheter aortic valve replacement (TAVR) from October 2014 to November 2019 were enrolled, excluding those with previous permanent pacemakers. Clinical, procedural, ECG, and pacemaker data were collected up to one year post-implantation. The study, authored by Ricardo Alves Pinto, found that 18.5% of patients received a permanent pacemaker after TAVR, with right bundle branch block being the major risk factor.

Use Cases

• Predicting permanent pacemaker implantation risk based on pre-existing conduction disturbances like right bundle branch block.
• Analyzing the resolution rate of new left bundle branch block over a 6-month follow-up period.
• Modeling ventricular pacing percentage over time for patients with advanced atrioventricular block versus those with LBBB and low-grade AVB.
• Investigating the association between newer generation valves or valve-in-valve procedures and reduced conduction disturbances.

Strengths

• Data covers 340 patient records with a 1-year follow-up period.
• Includes multiple data types: clinical, procedural, ECG, and pacemaker interrogation data.
• Statistical analysis provides specific odds ratios for risk factors, such as RBBB (OR=8.46 for advanced AVB).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
