Insights
This study demonstrates a novel totally endoscopic coronary artery bypass grafting technique for sequential arterial grafting of two anterior wall vessels on a beating heart. This minimally invasive approach offers a new option for treating complex coronary artery disease.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Techniques
- Robotic Surgery
Background:
- Coronary artery disease (CAD) necessitates revascularization when medical management is insufficient.
- Traditional coronary artery bypass grafting (CABG) can be invasive, involving sternotomy.
- Minimally invasive and off-pump techniques aim to reduce surgical trauma and improve patient outcomes.
Observation:
- A 50-year-old male presented with exertional angina due to critical stenosis in the left anterior descending artery and first diagonal branch.
- The patient was evaluated at a thoracic and cardiovascular surgery department in Germany.
- A new version of the da Vinci Surgical System was utilized for the procedure.
Findings:
- Successful sequential grafting of the left internal mammary artery (LIMA) to both the left anterior descending (LAD) artery and the first diagonal branch was achieved.
- The procedure was performed using a totally endoscopic coronary artery bypass grafting (TECAB) technique.
- Grafting was performed off-pump (without cardiopulmonary bypass) on the beating heart.
Implications:
- This represents the first reported case of sequential arterial off-pump grafting of two anterior wall target vessels using a totally endoscopic technique on a beating heart.
- This technique may offer a less invasive alternative for patients requiring bypass of multiple anterior coronary arteries.
- Further research and adoption of this robotic-assisted TECAB approach could expand minimally invasive treatment options for complex CAD.
Abstract:
A 50-year-old man was referred to the Department of Thoracic and Cardiovascular Surgery at the Johann Wolfgang-Goethe University (Frankfurt, Germany) with angina on exertion. An evaluation revealed critical stenosis involving the proximal portion of the left anterior descending artery and the first diagonal branch. The patient underwent successful sequential grafting of the left internal mammary artery to the left anterior descending artery and the diagonal branch using a totally endoscopic coronary artery bypass grafting technique on the beating heart with a new version of the da Vinci Surgical System (Intuitive Surgical, USA). To the authors' knowledge, this is the first report in literature to describe sequential arterial off-pump grafting of two anterior wall target vessels using a totally endoscopic technique on the beating heart.
