Pontages coronariens par mini-thoracotomie: bénéfices visibles avec l'expérience croissante de l'équipe traitante [Coronary artery bypass by mini-thoracotomy: noticeable benefits with clinical experience of the treatment team]
AIM OF THE STUDY: Minimally invasive coronary artery bypass surgery is fundamentally different as compared to open sternal approach under cardiopulmonary bypass. Modifications of the surgical, anesthesiologic and post-operative techniques are necessary before evaluation of its real benefit. We analyze the potential effect of a learning period on the short term results of this technique. METHODS: From July 1997 to February 1999, 20 patients were operated using this method. We compare the results of the first 10 patients (group 1: 8M/2F, 59.6 +/- 13.8 years) to those of the last 10 patients (group 2: 8M/2F; age = 63.2 +/- 6.1 years). DISCUSSION: Progress between the two groups is striking. Left anterior descending coronary clamping time could be reduced from 28.5 +/- 2.4 min. in group 1 to 22.2 +/- 1.8 min. in group 2 (p < 0.05), and operative time was reduced from 125 +/- 4 min. to 97 +/- 5 min. (p < 0.005). The post-operative atrial fibrillation rate diminished from 4/10 in group 1 to 1/10 in group 2.3/10 patients in group 1 suffered a post-operative pneumonia whereas none in group 2 had pulmonary complication. The stay in the intensive care unit could be reduced from 2.3 +/- 0.3 days to 1.4 +/- 0.2 days (p < 0.05) and the total post-operative stay diminished from 8.5 +/- 0.9 days to 4.7 +/- 0.5 days (p < 0.005). CONCLUSION: There are evidence for a learning period in minimally invasive cardiac surgery. Short term benefits of this technique are then evident as demonstrated by a reduction in the ICU stay and the hospital stay.
