Transcatheter refers to procedures or treatments that are performed via catheters (thin tubes) inserted into blood vessels or other parts of the body. Transcatheter procedures are minimally invasive, meaning they are less invasive than traditional surgical procedures and often result in shorter recovery times and fewer complications. Transcatheter procedures are commonly used in cardiovascular interventions, such as transcatheter aortic valve replacement (TAVR), where a new heart valve is inserted through the blood vessels instead of through open heart surgery. Transcatheter procedures are also used in interventional radiology, gastroenterology, and other fields to treat a variety of conditions. Overall, the field of transcatheter interventions is rapidly growing and evolving, with new technologies and techniques constantly being developed to improve patient outcomes and expand the types of conditions that can be treated using minimally invasive approaches.
