Title: Minimally Access Cardiac Surgery: Our Experience
With the advent of MICS the techniques to achieve it also needed to be changed and upgraded which includes access for cannulation for cardiopulmonary bypass (CPB). Right internal jugular vein percutaneous cannulation, together with the direct surgical cannulation of femoral vessels with minithoracotomy/ministernotomy proves to be a safe and effective tool in patients with body weight of above 20 kg for minimally access cardiac surgery. We use this technique for atrial septal defect (ASD) closure, aortic valve replacement (AVR), redo Tricuspid valve replacement (TVR) and mitral valve replacement (MVR).
Between May 2014 to May 2019 we performed minimally invasive closure of atrial septal defects, AVR, TVR and MVR with total peripheral cannulation in 103 patients. There were 64 females and 39 males Mean age was 25 years (range 8- 58 years), Spectrum of procedures include ASD closure in 81 patients (78.6%), AVR via minithoracotomy in 13 patients (12.6%) and AVR via ministernotomy in 3 patients (2.9%), redo TVR in 5 (4.8%), MVR in 1 patient (0.97%). Average cardiopulmonary bypass (CPB) time was 46 minutes (range 22 - 78 min) and average aortic cross-clamp time (AoX) 26 min (range 1245 min) in ASD closure group. In AVR group average CPB time was 91 min (range 72 - 120 min) and AoX time 76.5 min (range 65 - 109 min). In TVR group average CPB time 54 min (range 45 - 67 min) on beating heart. Only one MVR done in this period and CPB time was 82 min and AoX time was 65 min.
ASD closure, AVR, TVR and MVR with mini invasive approach is safe with very few manageable preoperative complications and good patient satisfaction.
