ABSTRACT

Minimally invasive cardiac surgery (MICS: Minimally Invasive Cardiac Surgery) through a minithoracotomy is becoming a standard approach for heart valve surgery. According to JCVSD data for 2018-2019, 42.6% of mitral valve surgeries were performed using the MICS approach. MICS has various advantages over the standard sternotomy approach, such as superior cosmesis, faster recovery and avoidance of sternal complications. However, caution cannot be overemphasized as procedure-related complications are yet to be fully addressed. These complications include chest wall bleeding, unilateral pulmonary edema, vascular injury, and leg ischemia. Some of these complications tend to occur more frequently during the learning curve period. A strict collaboration between surgeons, anesthesiologists, and operating staff is critical for avoid these complications.

ABSTRACT

@#Objective     To summarize the effectiveness of Bentall procedure through the right anterior mini-incision. Methods    The clinical data of patients who underwent Bentall via right anterior mini-incision from September 2020 to September 2021 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively analyzed. Results    A total of 14 males with an average age of 55.1±9.3 years and body mass index of 24.7±2.8 kg/m2 were enrolled. The cardiopulmonary bypass (CPB) time was 185.6±32.9 min, the aortic cross-clamping (ACC) time was 144.8±30.3 min, the ventilation time was 18.1±13.5 h, the time in the intensive care unit was 3.7±1.8 d, and the hospital stay time was 13.4±1.6 d. Postoperative complications occurred in 5 patients: 3 patients of pleural effusion, 1 patient of pericardial effusion and 1 patient of postoperative bleeding with secondary thoracotomy hemostasis. The median follow-up time was 4 (2, 6) months. There was no mortality in the hospital or during the follow-up. As for the learning curve, the ACC time, CPB time and operation time were significantly shortened after four cases (P<0.05). Conclusion    The right anterior mini-incision for Bentall operation is safe and effective, and has clinical value.

ABSTRACT

@#Objective    To summarize the early outcomes of totally thoracoscopic minimally invasive aortic valve replacement (AVR) and double valve replacement (DVR). Methods    The clinical data of patients who underwent totally thoracoscopic minimally invasive AVR or DVR in Guangdong Provincial People’s Hospital from April 2020 to January 2021 were retrospectively analyzed. The patients were divided into an AVR group and a DVR group according to the surgical method, and the clinical data of the two groups were compared. Results    Finally 22 patients were enrolled, including 14 males and 8 females with an average age of 50.0±11.2 years at operation. Eight patients were degenerative disease, 8 were rheumatic heart disease combined with valvular disease, and 6 were bicuspid aortic valve. Out of the 22 patients, 16 underwent AVR alone, and 6 underwent DVR. All patients completed the operation successfully, and there was no death. Perivalvular leakage during surgery occurred in 2 patients. The average cardiopulmonary bypass time was 187.0±39.9 minutes, and aortic cross-clamping time was 117.0 (99.0, 158.0) minutes. Duration of mechanical ventilation and intensive care unit stay was 9.5 (4.8, 18.3) hours and 41.0 (34.0, 64.0) hours, respectively. The volume of chest drainage at the first 24 hours after surgery was 214.0±124.6 mL, and the postoperative hospital stay was 5.5 (4.0, 8.3) days. The cardiopulmonary bypass time and aortic cross-clamping time in the DVR group were longer than those in the AVR group, and the volume of chest drainage at 24 hours after surgery was more than that in the AVR group, with a statistical difference (P<0.05). Echocardiography before hospital discharge showed paravalvular leakage in 1 patient. There was no death during follow-up of 5.9±3.0 months. Conclusion    The early outcome of totally thoracoscopic minimally invasive AVR and DVR is satisfactory, and the approach of surgery is worth exploring.

ABSTRACT

Case 1 of stuck valve was an 84 year old man, 25 years after mitral valve replacement (MVR) using a mechanical valve. Case 2 was a 67 year old woman, 18 years after the previous operation. These patients underwent re-do replacement of the prosthesis with a minimally invasive right thoracotomy approach using a microscope. Re-do cardiac surgery is commonly regarded high risk on account of difficulty in peeling the adhension, risk of injury to the heart, lung or large vessels, longer operation time, greater amount of transfusion, higher invasion and longer admission. In both cases however, because of microscope-assist and right thoracotomy MICS technique, we safely and successfully completed the operation without any unplanned troubles. We finally had a good course with a short admission, no perioperative transfusion or no perioperative complication.

ABSTRACT

In poststernotomy redo cardiac surgery, injury to cardiac structures during sternal division can lead to untoward results in the operation. These days, Minimally Invasive Cardiac Surgery (MICS) such as the right anterolateral thoracotomy approach is becoming popular. By using MICS technique in redo cardiac surgery, it may be possible to reduce the risk of injury to the vital structures because of avoiding full sternotomy with the reduction of the dissection area. Six redo cardiac surgery cases in which innominate vein or bypass graft was in close contact with the sternum were is considered difficult to perform via the right thoracotomy approach. We report the cases in which operations were safely conducted through the lower hemi-sternotomy.

ABSTRACT

Minimally invasive aortic valve replacement (MIAVR) through right antero-lateral thoracotomy (ALT) has several advantages over traditional anterior chest approaches (right anterior thoracotomy, or partial sternotomy). First, ALT is less affected by anatomical variation of the position of the ascending aorta, second, concomitant mitral valve surgery is possible, and third, outcome in cosmesis is better. MIAVR can be done under direct vision and endoscopic assist. Longitudinal axillary incision and thoracotomy through the third inter-costal space is appropriate to directly look down the aortic valve. Endoscopic assist and tying down the sutures using a knot-pusher are mandatory. MIAVR can also be done totally endoscopically. Three dimensional endoscope and independent working ports for the right and left hand are helpful. Appropriate working space for the endoscopic surgery is obtained by antero-lateral approach. Standard valve can be used in endoscopic AVR, without using fastener devices.

ABSTRACT

@#Objective    To evaluate the feasibility, safety, and short-term effect of minimally invasive ascending aorta surgery through a right anterior thoracotomy via the second intercostal incision. Methods    The clinical data of 13 patients who underwent minimally invasive ascending aorta surgery (including minimally invasive Bentall operation in 7 patients, minimally invasive Wheat operation in 2 patients, and minimally invasive ascending aorta replacement in 4 patients) through a right anterior thoracotomy via the second intercostal incision in our center from October, 2019 to September, 2020 were retrospectively analyzed. There were 12 males and 1 female at age of 19-69 (52.4±13.7) years. Results    The aortic cross-clamping time was 84.3±18.3 min. Three patients received blood transfusion, with the rate of 23.1%. The drainage volume in the first 24 hours after operation was 214.5±146.3 mL, with no redo for bleeding. The duration of mechanical ventilation was 19.0±11.3 hours and the length of intensive care unit stay was 1.8±1.3 days. The drainage tube was removed 2.5±1.0 days after operation. All the 13 patients recovered and discharged 6.4±2.0 days after operation, with no dead patients found. All patients survived with New York Heart Association (NYHA) functional classⅠandⅡduring a median follow-up of 8 months. Conclusion    Minimally invasive ascending aorta surgery through a right anterior thoracotomy via the second intercostal incision may be a safe and effective method with less injury and quick recovery.

ABSTRACT

@#Objective    To introduce a new type thoracic vest designed according to the incision characteristics of female patients undergoing totally thoracoscopic cardiac surgery. Methods    Sixty-one female patients undergoing totally thoracoscopic cardiac surgery from February 2019 to May 2020 in our department were enrolled. All female patients had hypermastia and (or) mastoptosis which covered the incision. They were randomly divided into a research group (group A, n=32) and a control group (group B, n=29). The group A used the new type thoracic vest, while the group B used the traditional single shoulder belt. The degree of satisfaction, visual analogue scale (VAS) score 24 hours after the thoracic drainage tube removed, the average time-consuming of dressing change, dressing frequency and the incision infection rate were compared between two groups. Results    The degree of satisfaction in the group A was higher than that of the group B (P<0.001). The VAS scores of pain, average time-consuming of dressing change and dressing frequency in the group A were less or lower than those of the group B (P<0.001). There was no statistical difference in the incision infection rate between the two groups (P=0.214), but incision infection rate of the group A was lower than that of the group B. Conclusion    The new type thoracic vest seems to be more beneficial for patients than traditional single shoulder belt. It is easy to use, increases the psychological satisfaction of patients, reduces the pain and the incision infection and improves work efficiency, which is worthy of clinical application.

ABSTRACT

@#Objective    To observe the short-term therapeutic outcomes of atrial septal defects (ASD) repair using on-pump beating-heart technique assisted by robotic surgery system (Da Vinci Si) or thoracoscopy. Methods    Clinical data of 50 patients undergoing ASD repair at the First Affiliated Hospital of Anhui Medical University from January 2015 to December 2018 were retrospectively analyzed. According to the different surgical methods, patients were divided into a robot group and a total thoracoscopy group. In the robot group, there were 35 patients including 11 males and 24 females, at an average age of 42.1±16.8 years, and in the total thoracoscopy group there were 15 patients including 8 males and 7 females at an average age of 38.4±10.9 years. During follow-up, the left ventricular ejection fraction, left and right atrial diameter, and right ventricular end-diastolic diameter in the cardiac Doppler echocardiography were recorded. The operation time, extracorporeal circulation time, ventilation time, postoperative ICU stay, postoperative hospital stay, perioperative pleural drainage and early complications were compared between the two groups. Results    In the perioperative period, the robot group had less operation time (3.8±0.3 h vs. 6.1±1.4 h), extracorporeal circulation time (72.3 ± 10.4 min vs. 139.1 ± 32.8 min), ventilation time (5.5±1.2 h vs. 9.5 ± 2.1 h), postoperative hospital stay (6.7±0.5 d vs. 9.8 ± 0.6 d) and thoracic drainage (253.4±26.8 mL vs. 289.3 ± 29.5 mL) than the total thoracoscopy group (P<0.05), while the postoperative complications were not statistically significant between the two groups (P>0.05). All patients were reviewed by color Doppler ultrasound at 1 month after operation. The postoperative dilated right atrium, right ventricle and left atrium were smaller than those before surgery. Conclusion    For patients undergoing ASD repair, robot-assisted and total thoracoscopy can achieve good results, but the robot group has more advantages in terms of operation time, extracorporeal circulation time, ventilation time, postoperative hospital stay and thoracic drainage.

ABSTRACT

Objectives : We sought to present data relative to valvular heart surgeries from the Japan Cardiovascular Surgery Database in 2017 and 2018 to show current status and trend in Japan. Methods : We extracted data relative to cardiac valve surgeries performed in 2017 and 2018 from the Japan Cardiovascular Surgery Database. We obtained total number of aortic valve replacement procedures and showed trend for these 6 years from 2013 to 2018. The operative mortality rates were shown for representative valve procedures stratified by age group with the aim of showing a bench mark of Japan. Data regarding minimally invasive procedures and transcatheter aortic valve implantation which the Japan Cardiovascular Surgery Database can provide were also presented. Results : Despite dramatic increase of number of transcatheter aortic valve implantation in 2017 and 2018 compared to in 2015 and 2016, surgical aortic valve replacement also increased from 26,054 to 28,202. Regarding the operative mortality of first time valve procedures, it was 1.8% in isolated aortic valve replacement, 0.9% in isolated mitral valve repair, 8.2% in mitral valve replacement with biological prostheses, and 4.6% with mechanical prostheses. For first time valve procedures with concomitant coronary artery bypass, the operative mortality was 5.2% in aortic valve replacement, 4.9% in mitral valve repair. Regarding prosthetic valve selection, 72.6% of patients had biological prosthesis for aortic valve replacement procedures in their 60's, showing trend of increasing percentages of biological valve choice. Regarding minimally invasive procedure, 31.8% of first time isolated mitral valve plasty were performed via right thoracotomy. Though patients who underwent surgery via right thoracotomy had better clinical outcomes, it was also apparent that the patients who underwent surgery via right thoracotomy had lower operative risk profile. Aortic clamp time and cardiopulmonary bypass time were longer in the right thoracotomy patients. 6.3% of the patients who had isolated aortic valve replacement underwent surgery via right thoracotomy. The right thoracotomy aortic valve replacement patients had better clinical outcomes and had more percentage of lower risk profile. The overall mortality of transcatheter aortic valve implantation and surgical aortic valve replacement were 1.5% and 1.8%, respectively. Conclusion : We reported data related to heart valve surgery in 2017 and 2018 from the Japan Cardiovascular Surgery Database.

Methods    Clinical data of 442 patients undergoing TTCS for atrial septal defect from May 2008 to December 2018 in Shanghai Yodak Cardiothoracic Hospital was analyzed retrospectively. There were 149 male and 293 female patients, aged 3-74 (29.1±14.3) years. Surgical procedures were performed through 3 ports at the right chest wall. Results    All the operations were completed successfully. Mean operative time was 1.5-4.6 (2.2±0.3) h. The mean extracorporeal circulation and aortic cross-clamp time was 28-118 (55.9±13.3) min and 8-78 (21.5±10.2) min, respectively. Mechanical ventilation and intensive care unit stay time was 3.5-122.0 (8.1±7.4) h and 13-141 (20.7±10.2) h, respectively. Postoperation drainage volume was 70-1 280 (251.8±131.5) mL. The hospital stay was 4-16 (7.1±1.4) d. Intraoperative and postoperative complications occurred in 15 patients (3.3%). The mean follow-up time was 1-128 (67.6±33.3) months, and during the period, there were 25 patients of atrial fibrillation, 25 patients of mild-moderate tricuspid valve incompetence, 1 patient of moderate tricuspid valve incompetence. There was no reoperation or residual shunt during the period of follow-up. And the heart function was improved. Conclusion    TTCS is a feasible, safe and minimal invasive approach for patients with atrial septal defect and has good short to medium-term outcomes.

ABSTRACT

OBJECTIVE@#To explore the feasibility, safety and mid-term outcome of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) surgery.@*METHODS@#Data of patients who underwent MICS CABG between November 2015 and November 2017 in Peking University Third Hospital were retrospectively analyzed. Results were compared with the patients who underwent off-pump coronary aortic bypass grafting (OPCABG) surgery over the same period. The two groups were matched in propensity score matching method according to age, gender, left ventricular ejection fraction, body mass index, severity of coronary artery disease, smoking, diabetes mellitus, hypertension, hyperlipidemia, renal insufficiency, history of cerebrovascular accident, and history of chronic obstructive pulmonary disease (COPD).@*RESULTS@#There were 85 patients in MICS CABG group, including 68 males (80.0%) and 17 females (20%), with an average age of (63.8±8.7) years; 451 patients were enrolled in OPCABG group, and 85 patients were matched by propensity score as control group (OPCABG group). There was no significant difference in general clinical characteristics (P>0.05). The average grafts of MICS CABG and OPCABG were 2.35±0.83 and 2.48±0.72 respectively (P=0.284). No conversion to thoracotomy in MICS CABG group or cardiopulmonary bypass in neither group occurred. There was no significant difference in the major adverse cardiovascular events (MACCEs, 1.17% vs. 3.52%), reoperation (2.34 vs. 3.52%), new-onset atrial fibrillation rate (4.70% vs. 3.52%) or new-onset renal insufficiency rate (1.17% vs. 0%) between MICS CABG group and OPCABG group (P>0.05). The operation time in MICS CABG group was longer than that in OPCABG group [(282.8±55.8) min vs. (246.8±56.9) min, P < 0.05], while the time of ventilator supporting(16.9 h vs. 29.6 h), hospitalization in ICU [(29.3±20.8) h vs. (51.5±48.3) h] and total hospitalization [(18.3±3.2) d vs. (25.7±4.2) d] in MICS CABG group were shorter than those in OPCABG group (P < 0.05). The total patency rate (A+B levels) of MICS CABG was 96.5% after surgery. There was no significant difference in MACCEs rate between the two groups [1.18%(1/85) vs. 3.61%(3/83), P>0.05] in 1-year follow up.@*CONCLUSION@#The MICS CABG surgery is a safe and feasible procedure with good clinical results in early and mid-term follow-up.

ABSTRACT

@#Minimally invasive cardiac surgeries are the trend in the future. Among them, robotic cardiac surgery is the latest iteration with several key-hole incision, 3-dimentional visualization, and articulated instrumentation of 7 degree of ergonomic freedom for those complex procedures in the heart. In particular, robotic mitral valve surgery, as well as coronary artery bypass grafting, has evolved over the last decade and become the preferred method at certain specialized centers worldwide because of excellent results. Other cardiac procedures are in various stages of evolution. Stepwise innovation of robotic technology will continue to make robotic operations simpler, more efficient, and less invasive, which will encourage more surgeons to take up this technology and extend the benefits of robotic surgery to a larger patient population.

ABSTRACT

BACKGROUND: Preoperative autologous blood donation (PABD) is a conservation strategy for reducing allogenic blood transfusion (ABT) during minimally invasive cardiac surgery (MICS). We aimed to evaluate the effects of PABD on the frequency of ABT and clinical outcomes in patients undergoing MICS.METHODS: We enrolled 113 patients (47.8±13.1 years, 50 men) undergoing MICS without preoperative anemia (hemoglobin >11 g/dL) between 2014 and 2017. Of these patients, 69 (the PABD group) donated autologous blood preoperatively and were compared to the non-PABD group (n=44). We analyzed the frequency of perioperative ABT and clinical outcomes.RESULTS: Baseline characteristics did not significantly differ between groups, although preoperative hemoglobin levels were lower in the PABD group. All operations were performed using a minimally invasive approach. Patients’ surgical profiles were similar. There were no cases of mortality or significant differences in early postoperative outcomes. During the early postoperative period, hemoglobin levels were higher in the PABD group. No significant difference was found in the frequency of ABT.CONCLUSION: Although the PABD group had higher postoperative hemoglobin levels, there was no clear clinical benefit in the early postoperative period, despite a great deal of effort and additional cost. Additional PABD in the setting of strict policies for blood conservation was ineffective in reducing ABT for young and relatively healthy patients who underwent MICS.

ABSTRACT

We report a case of minimally invasive surgery (MICS) for left ventricular aneurysm with a large mobile thrombus, which appeared after chemotherapy for malignant lymphoma. A 42-year-old man with a postinfarction left ventricular aneurysm was admitted to our hospital to receive chemotherapy for malignant lymphoma. Eight days after the first administration of anticancer drugs, echocardiography revealed a large mobile thrombus in the left ventricular aneurysm that was absent on admission. The patient was referred to our department, and left ventricular endoplasty was performed through a small left thoracotomy. He recovered rapidly, and chemotherapy was resumed a month after surgery. This suggests MICS to be a valuable option for left ventricular aneurysm repair.

ABSTRACT

A 15-year-old boy with coronary sinus type atrial septal defect (CS-ASD) was surgically treated with 3-port totally endoscopic technique. The patient was set in a left semi-lateral position. A 3 cm skin incision retracted by a small wound protector, a trocar for the endoscope, and a trocar for left-handed instruments were placed in the right antero-lateral chest. Cardio-pulmonary bypass was established via groin cannulation. After cardioplegic arrest, the CS-ASD was favorably exposed through the left atriotomy, and closed using a bovine pericardial patch. The total operation time was 112 min. The post-operative course was uneventful. Instead of the traditional median sternotomy and right atriotomy, small right thoracotomy and left atriotomy may be a promising alternative for closure of CS-ASD.

ABSTRACT

@#Objective    To monitor surgical quality and analyze learning curve of minimally invasive totally thoracoscopic cardiac surgery. Methods    We retrospectively analyzed the clinical data of 150 consecutive patients who underwent minimally invasive totally thoracoscopic cardiac surgery in the Guangdong General Hospital between January 2013 and December 2015. There were 60 males and 90 females at age of 43.1 years. There were 60 patients with atrial or ventricular septal defect repair, 12 patients with cardiac tumor resection, 53 patients with mitral valve replacement and 25 patients with mitral valve repair. According to the surgical sequence, all the patients were divided into 3 groups including a group A, group B, and group C with 50 patients in each group (every 10 patients as a sequence, every 5 sequence as a group). Surgical outcomes were compared among the 3 groups, and surgical quality was analyzed with descriptive statistics. Results    Surgical failure rate was 6.7% (10/150). There was no in-hospital mortality. Aortic cross-clamp time, cardiopulmonary bypass time and duration of mechanical ventilation, duration of ICU stay, duration of hospital stays of the group C were significantly shorter than those of the group A and group B. Analysis showed a significant learning curve effect in totally thoracoscopic cardiac surgery. When surgical cases reached about 100 cases, cardiopulmonary bypass and aortic cross-clamp time was shorter than the average value stably. Conclusion    Totally thoracoscopic cardiac surgery is safe and reliable. For the beginners, it needs about 100 patients of surgery to master the totally thoracoscopic cardiac surgery.

ABSTRACT

We report a case of minimally invasive cardiac surgery (MICS) for partial anomalous pulmonary venous return (PAPVR) to the high portion of the superior vena cava. A 34-year-old female was referred to our hospital for exertional chest oppression, and was diagnosed with PAPVR and a sinus venosus atrial septal defect. Two pulmonary veins were connected to the superior vena cava (SVC) : one to the SVC-atrial junction and the other to the high SVC adjacent to the azygos connection. We performed an intracardiac repair through a small right axillary incision. The postoperative course was uneventful. MICS may become a useful option for PAPVR repair.
