Session II: Invasive Diagnosis and Treatment-6154-Catheter Ablation of Atrial Tachycardia and Typical Atrial Flutter

Video Transcription

Video Summary

The video discusses mapping approaches and ablation techniques for different types of atrial arrhythmias. It explains the use of differential pacing and entrainment mapping to identify re-entry circuits and distinguish between macro-reentrant and focal atrial tachycardias. The video also highlights the importance of assessing scar tissue and fibrosis in the left atrium for scar-related macro re-entry circuits. It explains various ablation techniques for interrupting these circuits, such as creating ablation lines or targeting slow conduction areas. The video mentions the challenges of mapping and ablating atrial arrhythmias in post-cardiac transplantation patients, noting that suture lines can allow conduction between the recipient and donor atria, leading to different types of arrhythmias. It emphasizes the need to consider rejection as a possible cause of atrial arrhythmias in transplant patients. Overall, the video provides insights into the mapping and ablation strategies for different types of atrial arrhythmias and highlights considerations for treatment in post-transplant patients.
