Anesthesia for structural heart interventions.

Surgeries in general and cardiac procedures in particular are increasingly performed using catheter-based or minimally invasive techniques, often with sedation or general anesthesia. These new approaches require close cooperation and communication between the cardiologist and anesthesiologist to ensure patient safety. Anesthesia-related respiratory complications arising in the catheterization laboratory are more frequent and more severe than are seen in the operating room. The principals of safe anesthetic practice as they apply to procedures performed outside the operating room and suggestions to improve safety and outcome are reviewed in this article.
