PVC/NSVT Ablation in "Normal Hearts" w/ Pasquale Santangeli, MD, PhD (Part II)

Video Transcription

Video Summary

In this episode of EP on EP, Eric Prostowski interviews Pasquale Santanginelli about ventricular tachycardia (VT) ablation in patients with normal hearts. They discuss the challenges of targeting VT originating from the papillary muscles, including limited anatomical visualization and the need for contact during ablation. Santanginelli shares that cryoablation can be effective when radiofrequency ablation fails, as it is not arrhythmogenic and sticks to the papillary muscle. He also emphasizes the importance of careful power delivery to avoid complications and discusses the limitations of pace mapping in the outflow tract. They conclude by highlighting the need for better metrics to determine the success of ablation procedures for PVCs.
