Trends Favoring an Anatomical Approach to Radiofrequency Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit
Authors' conclusion
Over the 10-year period, the transpericardial approach became decreasingly performed, whereas the anatomic approach became increasingly performed with a satisfactory improvement in the RFCA outcomes of LVS-VAs.
Study context
- Population
- Patients with idiopathic ventricular arrhythmias originating from the LV summit undergoing radiofrequency catheter ablation (RFCA), single centre, 2009–2019
- Participants
- 88 consecutive patients
- Exposure
- Ablation approaches and outcomes across 3 periods
- Outcome
- RFCA success rate
Methodological detailssingle-centre, consecutive patients
- Single-centre
- Consecutive patients
Main finding
As reported in the abstract
- RFCA success rate did not significantly change from early to middle period
- Recent vs Middle: P = 0.0315
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|

Transpericardial approach usage
- Significantly decreased over the 3 periods
- Transpericardial approach use did not affect RFCA outcomes over the 3 periods
Anatomic approach usage
- Significantly increased over the 3 periods
Anatomic RFCA success rate
- Tended to increase from early to middle period
Number of endocardial locations of successful RFCA
- Increased over the 3 periods
