Abstract： Objective To find out goodness and weakness by comparing totally thoracoscopic surgery （TTS）and median sternotomy （MS）with cardiopulmonary bypass for pediatric open heart operation. Methods One hundred and fortyseven patients with ventricular septal defect(VSD) and atrial septal defect(ASD) were randomly divided into two groups according to operative methods, TTS group: patients were operated by totally thoracoscopy; MS group: patients were operated by median sternotomy with cardiopulmonary bypass. The clinical records from two groups were compared on operative effect, complications, hospitalization, ventilation time,variations of main data of blood routine test, drainage of pleura cavity, blood loss and transfusion, and pulmonary function. Results There were no death in two groups. There was VSD residual leak the same day after operation which was cured by TTS in one patient of TTS group. There was one case which bleeding was stopped by second operation in MS group. Followup visit were made to 41 patients for 3 months, no heart murmur was detected. The ultrasonic cardiography (UCG) showed that correcting of VSD and ASD were good and had no residual leak. The hospitalization,aortic clampping time, ventilation time and variations of main data of blood routine test, drainage of pleura cavity, blood transfusion and blood loss in TTS group had no significant difference to those in MS group (Pgt;0.05). Operating times was longer in TTS group than that in MS group, while stays in the intensive care unit were shorter in TTS group than that in MS group (Plt;0.01). Preoperative and 3 months postoperative pulmonary function of both teams had no statistically significant difference in two groups (Pgt;0.05). Conclusion TTS is a safe and effective method to pediatric VSD and ASD as MS is.
ObjectiveTo examine the differences between totally thoracoscopic surgery and median sternotomy in scope of trauma, postoperative recovery and postoperative complications. MethodsWe retrospectively analyzed the clinical data of 331 patients with cardiac myxoma in our hospital between January 2001 and November 2015. The patients were devided into 2 groups by the different methods of operation:a totally thoracoscopic surgery group including 196 patients with 71 males and 125 females at a mean age of 50 (42.00-57.50) years, and a median sternotomy group including 135 patients, with 53 males and 82 females at a mean age of 52 (38.00-61.00) years. The clinical records of the two groups were compared in scope of trauma, postoperative recovery, and postoperative complications. ResultsThere was shorter time in breathing machine and ICU time (P<0.001), and fewer volume in blood transfusion, blood loss (P<0.001) in the totally thoracoscopic surgery group. There was less pain and postoperative complications (P<0.001) in the totally thoracoscopic surgery group. The aortic clamp time in the totally thoracoscopic surgery group was not significantly different compared with that in the median sternotomy group (P=0.15) While cardiopulmonary bypass time was shorter in the median sternotomy group (P<0.001). ConclusionTotally thoracoscopic surgery is a safe and reliable method in treating cardiac myxoma. Our results suggest that totally thoracoscopic surgery has the advantage of fewer blood loss, blood transfusion, and postoperative complications compared with median sternotomy surgery. Totally thoracoscopic surgery leads to earlier recovery and less pain.
ObjectiveTo investigate the feasibility, safety and effectiveness of radiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery.MethodsThe clinical data of 107 patients with rheumatic mitral disease and atrial fibrillation who underwent mitral valve replacement and radiofrequency ablation at the same time in our hospital from January 2014 to October 2018 were retrospectively analyzed. The patients were divided into two groups: a totally thoracoscopic surgery group (n=51, including 20 males and 31 females, aged 50.57±5.24 years) and a median sternotomy group (n=56, including 21 males and 35 females, aged 52.12±5.59 years) according to the surgical methods. The preoperative, intraoperative and postoperative data of the patients were compared.ResultsAll operations were successfully completed without death. In terms of bleeding volume, drainage volume, ventilator-assisted breathing time, hospital stay and incision length, the totally thoracoscopic surgery group was better than the median sternotomy group, and the difference was statistically significant (P<0.05). The cardiopulmonary bypass time and radiofrequency ablation time in the totally thoracoscopic surgery group were longer than those in the median sternotomy group (P<0.05). There was no significant difference in the operation time, aortic occlusion time, postoperative complications, left ventricular ejection fraction, left atrial diameter and sinus rhythm maintenance between the two groups (P>0.05). There was no atrioventricular block, pulmonary vein stenosis, atrioesophageal fistula, coronary artery injury, stroke or hemorrhage during the follow-up.ConclusionRadiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery is safe and effective, and it is worthy of clinical application.
