Description
Tommaso Cambiaghi describes a 2026 surgical technique that runs heart-lung bypass and an Impella 5.5 heart pump through a single aortic opening using a direct Y-graft. Normally, starting bypass and placing the pump need separate aortic access points, adding incisions and complexity to an already high-stakes setup. The report gives step-by-step placement and removal instructions, noting it varies an established approach, uses no patient-specific data, and needed no ethics approval.
A ten-millimeter woven Dacron graft is formed into a Y shape. It is tunneled from a neck incision between the sternocleidomastoid muscle heads, and joined to the aorta through one opening under partial clamping. The graft is cleared of air through the pump sheath, the pump is placed before weaning from bypass, and the graft is later cut, shortened, and secured with slack for safe removal.
