[It's all over! : Complications in the EP lab and their solutions]

In cardiac electrophysiology, invasive procedures like catheter ablations or device implantations are getting increasingly complex. This poses challenges especially for electrophysiologists in training, not only to learn how to perform the procedure, but also how to manage possible complications. The present article uses exemplary case studies to present how to control complications and how to avoid them. The presented cases deal with complications such as air embolism in left atrial procedures, iatrogenic vascular injuries such as aortic dissection or dissection of the coronary sinus, complications and challenges with lead revisions, and pericardial tamponade. In each case, measures for avoidance as well as practical guidance for management are shown when the respective complication occurs.
