Abstract: A right mini-thoracotomy approach may be used for mitral valve repair without compromising clinical outcomes. Compared with conventional sternotomy, there is an increased distance to the cardiac structures from the mini-thoracotomy incision, which makes certain technical acts more demanding. One particular challenge is hemostasis at the antegrade cardioplegia cannula site. We propose a novel technique to remove an antegrade cardioplegia cannula using the COR-KNOT system. This technique negates the need for tying with a knot pusher and reduces the risk of aortic injury and troublesome bleeding.
