Specializing in Complex Cardiac & Thoracic Surgery

We are dedicated to providing highly-focused and exceptionally skilled surgical care to patients requiring cardiac or thoracic surgery. Our team routinely provides comprehensive surgical care to patients of all ages and wherever possible, uses minimally invasive techniques for improved outcomes.

The Bethencourt Group does not engage in “bait & switch” practices. Over 98% of Isolated Mitral Valves can be repaired via robot assist, regardless of the complexity of the repair needed. Over 90% of Isolated Aortic Valves can be replaced using minimally invasive surgical techniques. See our “results” page.

Robotic Procedures

Having performed over 800 surgeries using da Vinci ® surgical system, The Bethencourt Group are leaders in robot-assisted cardiac & thoracic surgery.

Some surgical procedures performed by The Bethencourt Group surgeons using the da Vinci® surgical system include: mitral valve repair or replacement, coronary artery bypass, lung biopsy or lobectomy & MAZE procedure for AFib. For a list of more robot-assisted procedures performed by our team of surgeons, visit our “services” page.

Minimally Invasive Procedures

Our team of surgeons are skilled in using other minimally invasive techniques such as a thoracoscopic, mini-thoracotomy (approx. a 2 inch incision), and endovascular surgery.

Some surgical procedures using the Minimally Invasive techniques include: aortic valve replacement via mini-thoracotomy or transcatheter (TAVR/TAVI), tricuspid valve repair or replacement, & thoracic aneurysm repair (TEVAR), pectus excavatum repair & lung biopsy or lobectomy.
