Minimally invasive surgery has been used in the treatment of some cardiovascular diseases. Port-Access surgery is a new minimally invasive technique that utilizes cardiopulmonary by-pass and a specialized catheter system that provides cardiopulmonary support and myocardial preservation. Extrathoracic cardiopulmonary support is established with femero-femoral bypass with kinetic assisted venous drainage. An endovascular catheter system allows for all the benefits of mechanical support as well as myocardial preservation. This catheter system includes an endoaortic balloon catheter which functions as an aortic cross clamp and antegrade cardioplegia delivery catheter, endopulmonary vent, and endocoronary sinus catheter used for administration of retrograde cardioplegia. An initial cohort of 20 patients was treated by the Port-Access surgical approach with cardiopulmonary bypass. Ten patients had coronary artery surgery and 10 patients had mitral valve surgery. The average bypass times were 94.4 min (coronary artery) and 152.8 min (mitral valve). The mean aortic occlusion times were 49.7 min (coronary artery) and 112.6 min (mitral valve). All patients were weaned from bypass. This initial patient series demonstrated that Port-Access surgery was feasible in selected patients. |
