OBJECTIVE To analyze two different 3-D endoscopic minimally invasive mitral valve surgery and conventional open heart mitral valve surgery for various mitral valve conditions in adults.
METHODS 200 patients were statistically analyzed (n=200). 100 patients in observational group underwent 3-D endoscopic minimally invasive mitral valve surgery, and other 100 patients in control group underwent conventional open heart mitral valve surgery. Ages 21 years to 79 years (median=40years). 98 males and 102 females.
RESULTS Total operation time, total CPB time, total aortic cross-clamp time, total intraoperative blood loss, total intraoperative blood transfusion, postoperative drain volume at 24 hours after surgery, total postoperative blood transfusion, total ICU stay, total hospital stay, amount of analgesic drugs during surgery, amount of analgesic drugs in postoperative ICU, amount of analgesic drugs after discharge, total postoperative complications, and total repetitive second surgery were significantly less in observational group than in control group (p<0.01). TEE assessment of mitral valve functions (MVF) like mitral regurgitation, mitral valve forward flow, etc. immediately after surgery, TTE assessment of MVF at 1 week after surgery, TTE assessment of MVF at 6 months after surgery, and total types of mitral valve conditions treated were not significant (p>0.05). Total cost of surgery was significantly higher for 3-D endoscopic minimally invasive mitral valve surgery than conventional open heart mitral valve surgery (p<0.05).
CONCLUSION 3-D endoscopic minimally invasive mitral valve surgery is significantly better than conventional open heart mitral valve surgery in adult patients in several different ways. 3-D endoscopic minimally invasive mitral valve surgery can be encouraged to perform in regular surgical practices.
