METHODS. Data from the initial experience of 40 patients operated on with the Port-Access technique are reported. Indication to surgery was mitral disease in 24 patients and coronary stenosis in 16 patients. Mean age was 52 years (range 32-75). Operations performed were: 8 mitral valvuloplasties, 16 valve replacements, 9 single CABG (associated with an MVR in one case), 1 double CABG, 6 triple CABG and one quadruple CABG. Coronary endoarterectomy was performed in 5 patients and left atrial isolation was associated with MV surgery in 5 cases. RESULTS. There were no operative deaths and every patient was discharged after a mean postoperative stay of 5.5 days (range 3-30). Postoperative course was complicated in 7 patients: surgical revision was necessary in 4 patients due to bleeding (through the mini-thoracotomy incision in 3 cases), 1 pacemaker was implanted for A-V block, one retained pulmonary catheter was removed through the mini-thoracotomy without the aid of cardiopulmonary bypass and in one case, there was an emergency conversion to median sternotomy due to a ventricular fibrillation unresponsive to usual resuscitative maneuvers a few hours after surgery. Some of these complications can be ascribed to the learning phase of this new technique and should disappear as experience is increased. CONCLUSIONS. Port-Access surgery is a new minimally invasive technique that utilizes a cardiopulmonary bypass with femoral access and a specialized catheter system that provides endoaortic clamping, pulmonary artery venting and myocardial preservation with infusion of cardioplegic solution in the aortic bulb or in the coronary sinus. Major contraindications to this technique are iliac-femoral disease or severe dilatation of ascending aorta. The aim of the Port-Access technique is to combine the aesthetic and functional advantages of the minimally invasive surgery with the wide range of surgical options that cardiopulmonary bypass can afford (to operate on atrioventricular valves and perform all the CABG that the patient need), without the limitations characteristic of the classic minimally invasive direct coronary artery bypass (MIDCAB) technique.
