(FIT)-Module 6 Lectures: Special Technology Sessions-Transseptal Catheterization (Callans)

Video Transcription

Video Summary

Professor Dave Callens from the University of Pennsylvania discusses techniques and complications related to transeptal catheterization. Originally used for measuring left atrial pressure in heart disease patients, this procedure is essential today for a variety of applications like atrial fibrillation ablation and structural heart procedures. Despite early complication rates of 2-6%, modern experiences in expert centers show major complications are now under 1%. Mastery of anatomy, practice, and effective mentoring are crucial for complication reduction.<br /><br />Prof. Callens emphasizes the importance of precise catheter positioning, considering structures like the aorta which sits immediately superior and anterior to the fossovalis. The fossa is bounds by the limbus at the superior part, requiring correct needle angling for safe atrium access. Various equipment, including sheaths, guide wires, and imaging techniques like intracardiac echo, aid in performing this safely while monitoring for potential complications.<br /><br />Advanced techniques are sometimes needed in difficult cases, such as using radiofrequency needles for fibrose septum or balloon atrial septoplasty. Overall, transeptal catheterization is crucial for left atrial procedures and relies on thorough anatomical understanding and precise intervention methods to remain a safe, effective practice.
