The first comprehensive resource on transseptal catheterization. Although the transseptal technique was described half a century ago, it has remained essentially unchanged. Recent advances in cardiac electrophysiology and left heart interventions have led to renewed interest in the technique as a means of delivering modern therapeutic interventions. Until now, the knowledge required for safely gaining access to the left atrium to perform catheter ablation for atrial fibrillation or other interventions has existed only in original publications and review articles. This textbook brings all of the relevant information about this technique under one cover, with top experts in each area addressing anatomy, indications, transseptal puncture, visualization technologies, interventional devices, challenging cases, complications, and emerging tools. Electrophysiologists and interventional cardiologists will find Transseptal Catheterization and Interventions invaluable for their work. For teachers and trainees, it will be a welcome teaching tool and resource. Transseptal Catheterization and Interventions was listed by the American Journal of Cardiology as one of the "Good Books in Cardiovascular Disease in 2010". - American Journal of Cardiology Vol. 107, Issue 8, Pages 1250-1251 Transseptal left heart catheterization is here to stay. It already plays an important role in the repertoire of both interventional cardiologists and clinical electrophysiologists, and it will play an increasingly important role in the future.
