ABSTRACT
Introduction: To date, totally 3D-endoscopy has primarily been employed in mitral, tricuspid, and aortic valve surgeries. Herein, we describe the first case of a pulmonary valve surgery using totally 3D-endoscopy. To the best of our knowledge, this is the first case of a totally endoscopic pulmonary valve surgery. Case report: A 56-year-old woman was provisionally diagnosed with a tumor arising from the left cusp of the pulmonary valve. Totally 3D-endoscopy was planned for tumor resection. The patient was placed in a modified right lateral decubitus position and underwent mild hypothermic cardiopulmonary bypass using the left femoral artery, right jugular vein, and right femoral vein. An on-pump beating-heart technique was used during this surgery. Trocars for the 3D-endoscopic system and surgical instruments were inserted through the third and fourth intercostal spaces. Upon incision of the pulmonary artery, the suspected tumor was revealed to be a hyperplastic left pulmonary cusp; therefore surgical resection was abandoned. The patient was discharged without any complications. Conclusion: This case demonstrates that a totally 3D-endoscopic approach may provide optimal views of the pulmonary valve. Moreover, this procedure would be a novelty in MICS.
ABSTRACT
@#Objective To investigate the surgical strategies and clinical efficacy of transmitral septal myectomy in the treatment of recurrent left ventricular outflow tract obstruction (LVOTO) after alcohol septal ablation. Methods The clinical data of patients with recurrent LVOTO after alcohol septal ablation from July 2020 to July 2021 in the Department of Cardiac Surgery, Guangdong Provincial People's Hospital were retrospectively analyzed. Patients were preoperatively evaluated by echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography, 3D modeling and printing technology. A personalized surgical strategy was preoperatively developed according to multimodality imaging assessment, while visual exploration was performed on the digital model and simulated surgical resection was performed on the printed model. Results Two female patients were enrolled, aged 62 years and 64 years, respectively. Totally endoscopic transmitral extended myectomy was successfully performed on both patients with aortic cross-clamping time of 96 min and 85 min, respectively. LVOTO was relieved immediately (subaortic peak pressure gradient decreased from 100 mm Hg to 4 mm Hg and from 84 mm Hg to 6 mm Hg, respectively) and the mitral regurgitation significantly improved after the procedure. No patient had complete atrioventricular block or required permanent pacemaker implantation. The patients were discharged uneventfully without postoperative complications. Conclusion Personalized totally endoscopic transmitral extended myectomy combined with multimodality imaging assessment and 3D modeling and printing has an acceptable clinical effect in patients with recurrent LVOTO after alcohol septal ablation. The procedure can precisely resect the hypertrophic septal myocardium while avoiding serious complications such as septal perforation or complete atrioventricular block.
ABSTRACT
@#Objective To investigate the effectiveness and safety of totally endoscopic transmitral myectomy (TETM) for hypertrophic obstructive cardiomyopathy (HOCM), comparing with traditional sternotomy modified Morrow procedure (SMMP). Methods Thirty-eight patients with HOCM who needed surgical intervention were selected from our hospital in 2019, including 14 males and 24 females, with an average age of 56 (44-68) years. According to the operation method, they were divided into a TETM group (n=18) and a SMMP group (n=20). Appropriate patients were screened by propensity matching scores. Finally, the clinical data of two matched groups were compared and
ABSTRACT
Objective:To study the effect of totally endoscopic surgery and Miccoli surgery for papillary thyroid microcarcinoma. Methods Totally 64 patients with papillary thyroid microcarcinoma from April 2013 to April 2014 in our hospital were divided into the ob-servation group and the control group according to a random number table.And the intraoperative and postoperative situation of the two groups were compared.Results The number of lymph node dissection,postoperative hospital stay,hospital costs of the two groups had no sig-nificant difference (P >0.05).The blood loss,operative time,drainage time,amount of drainage,incision length,time of postoperative recov-ery of the observation group were significantly less than those of the control group with statistical significance (P <0.05).But the cosmetic score of observation group after operation was lower than that of the control group,and there was a significant difference (P <0.05).Postop-erative pain grade of the observation group was better than the control group with statistical significance (P <0.05).The complication rate of control group was significantly higher than the observation group (P <0.05).Conclusion Miccoli surgery for papillary thyroid microcarci-noma has more advantages compared with totally endoscopic surgery in terms of blood loss,operative time,drainage time,amount of drainage, incision length,time of postoperative recovery,and degree of pain.Moreover,it has a lower complication rate and high security,which should be the first choice in clinic surgery.
ABSTRACT
As innovative technology continues to be developed and is implemented into the realm of cardiac surgery, surgical teams, cardiothoracic anesthesiologists, and health centers are constantly looking for methods to improve patient outcomes and satisfaction. One of the more recent developments in cardiac surgical practice is minimally invasive robotic surgery. Its use has been documented in numerous publications, and its use has proliferated significantly over the past 15 years. The anesthesiology team must continue to develop and perfect special techniques to manage these patients perioperatively including lung isolation techniques and transesophageal echocardiography (TEE). This review article of recent scientific data and personal experience serves to explain some of the challenges, which the anesthetic team must manage, including patient and procedural factors, complications from one‑lung ventilation (OLV) including hypoxia and hypercapnia, capnothorax, percutaneous cannulation for cardiopulmonary bypass, TEE guidance, as well as methods of intraoperative monitoring and analgesia. As existing minimally invasive techniques are perfected, and newer innovations are demonstrated, it is imperative that the cardiothoracic anesthesiologist must improve and maintain skills to guide these patients safely through the robotic procedure.

ABSTRACT
BACKGROUND: Minimally invasive cardiac surgery has emerged as an alternative to conventional open surgery. This report reviews our experience with atrial septal defect using the da VinciTM surgical robot system. MATERIALS AND METHODS: This retrospective study included 50 consecutive patients who underwent atrial septal defect repair using the da VinciTM surgical robot system between October 2007 and May 2011. Among these, 13 patients (26%) were approached through a totally endoscopic approach and the others by mini-thoracotomy. Nineteen patients had concomitant procedures including tricuspid annuloplasty (n=10), mitral valvuloplasty (n=9), and maze procedure (n=4). The mean follow-up duration was 16.9+/-10.4 months. RESULTS: No remnant interatrial shunt was detected by intraoperative or postoperative echocardiography. The atrial septal defects were mainly repaired by Gore-Tex patch closure (80%). There was no operative mortality or serious surgical complications. The aortic cross clamping time and cardiopulmonary bypass time were 74.1+/-32.2 and 157.6+/-49.7 minutes, respectively. The postoperative hospital stay was 5.5+/-3.3 days. CONCLUSION: The atrial septal defect repair with concomitant procedures like mitral valve repair or tricuspid valve repair using the da VinciTM system is a feasible method. In addition, in selected patients, complete port access can be helpful for better cosmetic results and less musculoskeletal injury.
