Breakthrough in Minimally Invasive Coronary Artery Bypass: The VECTOR Method

The VECTOR (ventriculo-coronary transcatheter outward navigation and re-entry) technique is the first reported minimally invasive coronary artery bypass performed without a chest incision in a human.

Unlike conventional coronary artery bypass grafting, which relies on midline sternotomy and cardiopulmonary bypass, VECTOR avoids a chest incision and uses targeted vascular access to achieve revascularization.

By minimizing bony disruption and broad thoracic exposure, the approach alters early surgical morbidity and rehabilitation trajectories compared with sternotomy‑based and standard off‑pump alternatives.

At six months, the patient did not show signs of coronary artery obstruction.
