Description of the Step-by-Step Technique With Snare Catheter for TAVR in Horizontal Aorta

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Transcatheter aortic valve replacement (TAVR) is a common procedure for aortic stenosis.
• A horizontal aorta anatomical variation presents unique challenges during TAVR procedures.
• Navigating complex aortic anatomies requires specialized techniques for successful TAVR outcomes.

Observation:

• The study focuses on five patients diagnosed with aortic stenosis and a horizontal aorta.
• These patients underwent TAVR utilizing self-expanding prostheses.
• The procedure's difficulty was noted as intermediate.

Findings:

• The presented cases demonstrate the successful application of a specific technique involving a snare catheter.
• This technique aided in overcoming the procedural challenges posed by a horizontal aorta during TAVR.
• The use of self-expanding prostheses was consistent across all cases.

Implications:

• This approach offers a potential solution for TAVR in patients with horizontal aortas.
• The snare catheter technique may improve procedural success rates and patient outcomes.
• Further research could validate this technique in larger patient cohorts with similar anatomical variations.
