Transcatheter aortic valve implantation – What does the anaesthetist need to know and pay attention to?

Abstract

Recent advancements in the field of cardiovascular surgery have been dominated by 3 aspects that comparably challenge a sophisticated cardiological, surgical and anaesthesiological management of this patient population. The proportion of elderly patients with relevant comorbidities increases steadily, and the number of combined cardiac surgical procedures is rising in this elderly population. A very important innovation in the last decade pertaining to the treatment of elderly patients at high risk suffering from significant aortic stenosis is the minimally invasive transcatheter aortic valve implantation (TAVI). Over the last 7 years this interventional-surgical "hybrid-procedure" has increased in numbers from almost 0 to 10,500 procedures in 2013 in Germany, performed at more than 80 centers. These patients relevant comorbidities accounting for a high risk of perioperative complications and moreover for a high mortality. The combination of a patient at high risk with the specific characteristics of the TAVI procedure necessitates to update the required skills of anaesthetists responsible for providing care for this kind of procedure.
