STOPSTORM at EHRA 2022
STOPSTORM was present in full force at the EHRA 2022 meeting in Copenhagen April 3-5.
Session on Ablation of Ventricular Arrhythmias
Session type: Moderated Posters Date: 3 April Start time: 17:00
- Stereotactic body radiotherapy for refractory ventricular tachycardia: the overall czech experience: Petr Peichl (IKEM - Prague, Czechia) presented the Czech experience, with 3 cases of redo STAR
- Recurrences after stereotactic arrhythmia radioablation for refractory ventricular tachycardia: Claudia Herrera Siklody (University Hospital Centre Vaudois (CHUV) - Lausanne, Switzerland) presented sites of VT recurrences after STAR in the CHUV series
- Stereotactic arrhythmia radioablation in europe: treatment planning benchmark results of the STOPSTORM consortium: Etienne Pruvot (University Hospital Center Vaudois (CHUV), Department of Cardiology - Lausanne, Switzerland) presented the PTV delineation survey. The audience noticed the high variability regarding the delivery of RT to the stomach for the 1st case, on the left lung for the 2nd case and on the coronary arteries for the 3rd case. The variability was said scary despite strict recommendations. Several questions arose whether the workflow could be performed in a timely manner, whether a fiducial was required and about the most determinant aspect of the workflow. Conclusion was that there is quite some room for harmonization, and that such a variability will provide data on complications and whether some organs are indeed at risk.
STOPSTORM Posters:
- B. Balgobind et al. STOPSTORM Multi-Centre Critical Structures Contouring Benchmark Results:
A high accuracy regarding standard critical structures was achieved. In the case of heart substructures some deviations occurred, which lead to new definitions for contouring within the consortium. A close collaboration between radiation oncologist and cardiac electrophysiologist is recommended.
- Melanie Grehn et al. STOPSTORM Survey Results of STAR practice in Europe:
Experience in STAR within the STOPSTORM consortium is adequate, while the survey shows areas of harmonisation and optimisation need for substrate mapping, target delineation, dosimetry and quality assurance which will be addressed in the STOPSTORM project work-packages.
