Intracardiac 3D Echocardiography Improves Outcomes in Transaortic Valve Replacement Procedures (TAVR)

Improved 3D visualization and the elimination of general anesthesia during TAVR procedures improve patient care, workflow and efficiency.

Dr. Brijeshwar Maini, who heads the department of Advanced Cardiac and Endovascular Interventional Laboratory of Pinnacle Health in Pennsylvania, has been using the ACUSON AcuNav V ultrasound catheter to guide Transaortic Valve Replacement Procedures (TAVR),
also known as Percutaneous Aortic Valve Replacement (PAVR) in patients with severe aortic stenosis.

The superior visualization of the heart anatomy and guidance of the valve prosthesis through the vessel using intracardiac 3D echocardiography improves the quality of this minimally invasive procedure. In addition, using the ACUSON AcuNav V catheter enables a safer and faster procedure by allowing the physician to perform the complex TAVR procedure under conscious sedation as opposed to general anesthesia, which is required when using conventional transesophageal echocardiography (TEE) image guidance.

Patient recovery after sedation without the need of intubation is much faster. In addtion, high-risk patients who cannot tolerate general anesthesia can safely and reliably undergo TAVR procedures. The ACUSON AcuNav V ultrasound catheter also reduces the amount of radiation for the patient since the valve placement as well as pre-procedural and post-procedural assessment can be performed under ultrasound visualization requiring minimal fluoroscopy.
