ABSTRACT

@#For patients with aortic valve disease who require replacement of their native valve, surgical aortic valve replacement (SAVR) has been the standard of care. Due to the hemorrhage and thromboembolic risks of long-term anticoagulation therapy for mechanical prosthesis, bioprosthetic aortic valve replacement (AVR) has a trend to be used in younger patients, which raising the concern for the durability of bioprosthetic valves. The newly published 5-year outcomes of PERIGON trial, with no structural valve deterioration, again demonstrated the favorable durability of the new generation bioprosthetic valves, further providing the evidence of using bioprosthetic AVR in younger patients. At the meantime, the rapid progress of transcatheter aortic valve implantation (TAVI) has brought a new treatment option. For younger patients with low risks, choosing SAVR or TAVI becomes a critical decision. This paper reviews the outcomes of PERIGON trial and its implications to the clinical practice and research of bioprosthetic AVR.

ABSTRACT

Objective:To explore the clinical effect of robot-assisted core decompression combined with bone grafting in the treatment of early-stage osteonecrosis of femoral head.Methods:The data of 49 patients (84 hips) who attended the Department of Orthopedics and Joint Surgery of the Second Affiliated Hospital of Xi'an Jiaotong University from August 2019 to February 2021 were retrospectively analyzed. All the patients suffering Association Research Circulation Osseous (ARCO) II stage of osteonecrosis of femoral head underwent core decompression and bone grafting. Among the patients undergoing surgery, 30 patients (54 hips), including 19 males and 11 females, aged 44.3±5.4 years (range, 21 to 59 years) were treated with conventional surgical methods, and 19 patients (30 hips), including 12 males and 7 females, aged 41.4±7.2 years (range, 20 to 58 years), were assisted by the orthopedic robot navigation system. All operations were performed by the same operator. All patients were informed of the conventional and robotic surgical options by the surgeon at admission, and the patients made the decision. The baseline data of the two groups of patients, the time of unilateral operation, the number of unilateral X-ray fluoroscopy, the Harris hip score at the last follow-up after surgery, the visual analog score (VAS), and the collapse rate at the last follow-up were collected and compared.Results:A total of 41 patients (70 hips) were followed up, including 24 cases (42 hips) in the conventional surgery group and 17 cases in the robot-assisted group (28 hips). The average follow-up time of all cases was 14.6±4.8 months (range, 3 to 21 months). At the last follow-up, a total of 13 patients (13 hips) suffered femoral head surface collapse, including 11 patients in the conventional surgery group (11 hips) and 2 patients in the robot-assisted group (2 hips). The rate of femoral head collapse between the two groups had statistical difference ( P=0.045). The average operation time of unilateral hip in the conventional operation group was 21.3±5.4 min, and 16.8±3.3 min in the robot-assisted group, with significant difference ( t=3.94, P<0.001). The number of X-ray fluoroscopy of unilateral hip in the conventional operation group was 14.4±3.8 times, and 9.6±2.1 times in the robot-assisted group, with significant difference ( t=6.08, P<0.001). The Harris hip score before surgery in the conventional surgery group was 68.4±4.5 points, and 85.1±3.8 points at the last follow-up, while the preoperative Harris hip score of the robot-assisted surgery group was 67.2±3.9 points, and 86.5±4.4 points at the last follow-up. The Harris hip scores at the last follow-up of the two groups were significantly different from those before the operation, but there was no difference between the two groups after surgery ( t=1.09, P=0.283). The preoperative VAS of the conventional surgery group was 4.8±1.7 points, and 1.7±0.8 points at the last follow-up. The preoperative VAS of the robot-assisted surgery group was 5.1±1.5 points, and 0.9±0.3 points at the last follow-up. Τhere were significant differences between the two groups regarding the VAS in the last follow-up ( t=3.92, P<0.001). Conclusion:Core decompression combined with bone grafting have a definite effect in the treatment of osteonecrosis of ARCO II stage of osteonecrosis of femoral head. Compared with conventional surgery, robot-assisted surgery can achieve better short-term results and head preservation rate.

ABSTRACT

Objective:To analyze and evaluate the safety and efficacy of a Chinese domestically manufactured Heart Con-type implantable third-generation magnetic and hydrodynamic levitation left ventricular assist device(LVAD) for the treatment of end-stage heart failure(ESHF), by reporting the results of eleven-center clinical trial on 50 cases.Methods:This study was a multicenter clinical trial, designed by means of prospective, multicenter and single-group target value. 50 subjects with ESHF were competitively enrolled and treated with HeartCon as the LVAD in eleven centers. The primary efficacy measure was survival, defined as either the subjects experiencing the transition to heart transplantation(HT) or myocardial recovery assisted by the device within 90 days, or as successfully assisted by the LVAD for full 90 days after implantation. The target survival rate was 60%, other observations included implantation success rate, mortality, pump failure needing replacement or emergency heart transplantation.Results:All enrolled 50 patients received LVAD implantation successfully, 46 survived with the pump for 90 days, 1 patient transitioned to heart transplantation, and 3 patients experienced pump thrombosis, within which 2 patients underwent pump replacement and continued to live with the pump for 90 days, and the other one received emergency heart transplantation. There were no dropout subjects. The survival rate at full 90 days after HeartCon implantation was 100%. The survival rates with pump in the full set analysis and the protocol set analysis were 96.00% and 95.92% respectively, which were higher than the target value of 60%. The differences were both statistically significant( P<0.05). Conclusion:The results of the multicenter clinical trial with the largest sample size in China using domestically manufactured third-generation LVAD has demonstrated that, HeartCon is a safe and effective LVAD to treat ESHF patients.

ABSTRACT

Objective:Exploring the clinical efficacy of using ultra-thin lobulated anterolateral thigh perforator flap(ALTPF) with retrograde separation of perforating vessels from the superficial and deep junction layer of the superficial fascia to repair large soft tissue defects in the foot.Methods:From August 2021 to November 2022, 8 patients (5 males and 3 females) were admitted to the Second Department of Hand and Foot Surgery, the Affiliated Central Hospital of Dalian University of Technology. The patients were 28 to 52 years old in age. The soft tissue defects were located in dorsal and plantar foot. At the plantar foot, the wound involved the weight-bearing area with explosion of bone, tendon or internal fixtures. The area of soft tissue defects was 6.0 cm × 5.0 cm - 16.0 cm × 8.0 cm, and the sizes of ALTPF were 8.0 cm ×5.5 cm - 18.0 cm × 8.5 cm. Preoperative high frequency CUD combined with CTA angiography were employed to locate the 2 flap perforator vessels. By keeping the perforator vessels at center and according to the soft tissue defect area and the wound shape, an ALTPF with a proper size and shape was designed in anterolateral thigh. The perforator were separated in the boundary layer between superficial and deep fascia, where it helped to obviously thin the flap. After the flap was harvested, it was further lobulated between the 2 perforators into 2 lobes after having confirmed the effective blood supply. Finally the lobulated ALTPF was transferred to covered the defect in foot. Cautions should be taken to ensure that the flap covered the weight-bearing area of foot. All the donor sites were directly sutured. Postoperative follow-up was conducted to observe the survival of flaps and the functional recovery of the reconstructed site, also to evaluate the clinical effect. Postoperative follow-up included outpatient visits and reviews over WeChat or telephone. Recovery of the ankle motor function was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) ankle-hind foot score scale.Results:All 8 ALTPF survived. Over 6 to 18 months (10.8 months in average) of follow-up, the transferred flaps had good blood supply, soft in texture, with good elasticity and thin in appearance. Appearance and function of donor sites recovered well, except 1 patient who had mild scar hyperplasia. The plantar flap had good abrasion resistance. No flap damage, bleeding or granulation tissue hyperplasia occurred when walking. The mean score of AOFAS ankle-hind foot score achieved 95.6.Conclusion:The application of ultra-thin lobulated ALTPF with retrograde separation of perforating vessels from the superficial fascia at the junction layer for repairing large soft tissue defects in the foot has good clinical efficacy.

ABSTRACT

Objective:To evaluate the outcomes of aortic root repair in acute type A aortic dissection (ATAAD) with aortic sinus involvement.Methods:The clinical data of patients with ATAAD involving the aortic sinus and an aortic root diameter of ≤45 mm who were treated from January 1, 2015, to December 31, 2016, were collected. Patients were divided into group A (involvement of one aortic sinus or part of one aortic sinus) and group B (involvement of more than one aortic sinus). The effectiveness of aortic root repair in ATAAD with sinus involvement was analyzed by comparing the preoperative imaging characteristics and postoperative results between the two groups.Results:The study cohort comprised 155 patients, including 100 patients in group A and 55 in group B. There were no differences between the two groups in baseline characteristics, aortic root diameter, 30-day mortality, and complication rates. During an average follow-up of(49.1±14.6) months, there was no difference between the two groups in the survival rate (92.0% vs. 89.5%, P=0.61). The aortic root diameter at follow-up showed no progressive expansion compared with preoperatively in either of the two groups[(38.1±3.6) mm vs. (37.9±3.5)mm, P=0.92, A; (38.4±4.1) mm vs. (38.3±3.6) mm, P=0.74, B]; furthermore, there was no difference between the two groups in aggravation of aortic regurgitation. Conclusion:Aortic root repair achieves satisfactory medium-term outcomes in ATAAD with more than one aortic sinus involved, but the long-term outcomes need to be evaluated.

ABSTRACT

Objective:To retrospectively analyze the treatment of 25 cases of lower necrotizing fasciitis.Methods:A total of 25 patients with lower limb necrotizing fasciitis (13 males and 12 females), with mean age 63 years old (48-75 years old) in Dalian Municipal Central Hospital from September 2016 to December 2020. After admission, the patient′s general physical condition was strictly evaluated, the relevant preoperative examination was improved, and the necrotizing fasciitis laboratory risk index (LRINEC) score was performed. In the absence of surgical contraindication, multiple debridement was performed, leaving the necrotic tissue removed for general bacterial culture and drug sensitivity test in parallel. After debridement, eight patients showed a large area of skin necrosis, and amputation was selected. The other 17 patients chose limb protection treatment after debridement, and adopted debridement and free skin grafting. After surgery, patients were encouraged to strengthen rehabilitation exercise to restore limb function to the maximum extent.Results:With followed up 0.6 to 3.0 years, with an average of 1.8 years. Methods include outpatient return visit, WeChat contact or telephone inquiry. The skin survived in 17 patients with mean healing time (27.5 ± 6.9) d. Eighteen patients were multiple bacterial infections and seven patients were single bacterial infections. All patients had no joint dysfunction caused by scar contracture, and reinfection in the skin grafting area.Conclusions:Necrotizing fasciitis requires early diagnosis and early treatment, with correct choice of treatment method is closely related to the patient′s prognosis.

ABSTRACT

@#Objective    To discuss the feasibility of establishment of animal model of "functional" bicuspid aortic valve with swine and observe its effect on the wall shear stress inside the aorta. Methods    Four common Shanghai White Swine with body weight between 50 kg to 55 kg were selected. Under general anesthesia and cardiopulmonary bypass, the aortic transverse incision approach was used, continuous suture with 6-0 polypropylene to align the left and right coronary valve leaflets to create a bicuspid valve morphology. After the operation, echocardiography was used to observe the aortic valve morphology and the hemodynamic changes of the aortic valve orifice. The effect on the wall shear stress inside the aorta was studied with 4D-Flow magnetic resonance imaging (MRI). Results    A total of 4 swine "functional" bicuspid aortic valve models were established, with a success rate of 100.0%. Echocardiography showed that the blood flow velocity of the aortic valve orifice was faster than that before the operation (0.96 m/s vs. 1.80 m/s). 4D-Flow MRI showed abnormally increased wall shear stress and blood flow velocity in the aorta of the animal models. After the surgery, in model animals, the maximal wall shear stress inside the ascending aorta was greater than 1.36 Pa, and the maximum blood flow velocity was greater than 1.4 m/s. Conclusion    Establishment of the animal model of "functional" bicuspid aortic valve in swine is feasible, scientific and reliable. It can be used in researches on evaluating the pathophysiological changes.

ABSTRACT

@#Although heart transplantation remains to be the optimal treatment for advanced heart failure, its use has been largely limited due to shortage of available donor organs. Over the past two decades, left ventricular assist device (LVAD) has been significantly modified in size, durability and hemocompatibility. In addition to the bridge to transplantation, LVAD has become an attractive alternative to heart transplantation for end-stage heart failure as destination therapy for unsuitable candidates. Although the performance of LVAD has been improving greatly in recent years, there are still great challenges in the management of device complications and low quality of life after implantation. This review will summarize the types of LVAD, indications for implantation, postoperative management and adverse events.

ABSTRACT

Left ventricular assist devices(LVAD) has become the main treatment for advanced heart failure, which effectively reduced the mortality of patients with advanced heart failure. However, postoperative right ventricular failure(RVF) has been a long-term challenge in the treatment of LVAD. At present, postoperative RVF is not only difficult to predict, but also difficult to treat. The lack of long-term right ventricular assist device has limited the impact that mechanical circulatory support can provide to patients with biventricular failure. This review summarizes the prevention and treatment of right heart failure after left ventricular assist device transplantation and explores the direction of future research.

ABSTRACT

@#Objective    To explore the clinical value of soluble suppression of tumorigenesis-2 (sST2) in replacement of N-terminal fragment of the brain natriuretic peptide precursor (NT-proBNP) in cardiac function evaluation in renal failure patients after cardiac surgery. Methods    Sixty patients with renal insufficiency after cardiac surgery from January 2019 to June 2019 were divided into a test group, including 34 males and 26 females, with an average age of 49-78 (63.3±4.5) years. Another 60 patients with normal renal function were divided into a control group, including 37 males and 23 females, with an average age of 53-77 (61.7±3.8) years. The perioperative left ventricular ejection fraction, cardiac troponin T, creatine kinase-MB, sST2 and NT-proBNP were compared. Results    In patients of the test group, the NT-proBNP level increased significantly during perioperative period, and the change range was different from other cardiac function indexes. The change of sST2 in perioperative period was similar to other cardiac function indexes, which could reflect the change degree of cardiac function after operation. Conclusion    sST2 is more important to reflect the change degree of cardiac function in patients with renal dysfunction after cardiac surgery than NT-proBNP.

ABSTRACT

@#Objective    To detect the expression of PITX2 and KCNQ1 in the left atrial appendage of patients with atrial fibrillation after modified mini-maze procedure, and to detect the clinical risk factors of different types of atrial fibrillation. Methods    We collected left atrial appendage tissue of 59 atrial fibrillation patients who received modified mini-maze procedure and left atrial appendectomy from February 2017 to August 2018. The expression levels of PITX2 and KCNQ1 of left atrial appendage tissue were quantitatively analyzed by western blotting assay between paroxysmal attial fibrillation and persistent atrial fibrillation groups. The correlation between protein expression and prognosis after surgery was also analyzed based on clinical data. Results    Binary-logistic regression analysis showed that KCNQ1 expression level was an independent risk factor for the progression from paroxysmal atrial fibrillation to persistent atrial fibrillation. Receiver operating characteristic (ROC) curve confirmed that KCNQ1 expression level (the ratio of KCNQ1 to actin in the analysis) was 0.60, which was the best cut-off point for the progression of paroxysmal atrial fibrillation to persistent atrial fibrillation. Conclusion    High expression of KCNQ1 in left atrial appendage is a risk factor for progression from paroxysmal atrial fibrillation to persistent atrial fibrillation.

ABSTRACT

@#The advent of transcatheter aortic valve replacement (TAVR) has brought up a new treatment option for patients with severe aortic valve disease. However, with the continuous expansion of surgical indications, problems such as structural valve deterioration caused by biological prosthesis have become increasingly prominent. In the newly announced 5-year follow-up results of COMMENCE (SAVR) trial, the aortic bioprosthesis using the new RESILIA biotissue material demonstrated extraordinary clinical safety, efficacy and durability with zero structural valve deterioration and excellent hemodynamic evaluation results. As a result, patients with valvular heart disease have more diverse therapeutic options. However, the choice between surgical aortic valve replacement (SAVR) and TAVR, biological prosthesis and mechanical prosthesis, etc, has become more and more prominent, which brings more difficulties to clinicians. This paper reviews the research background, 5-year follow-up results of COMMENCE trial and the implications for aortic valve surgery in China.

ABSTRACT

Objective:To investigate the effectiveness and safety of transcatheter closure of atrial septum defect(ASD) in adults using echocardiography as the only imaging tool.Methods:From April 2017 to August 2019, 118 patients with congenital atrial septum defect were treated by cardiac surgery in Zhongshan Hospital affiliated to Fudan University. There were 31 males and 87 females, aged 15-72 years old[mean(40.3±15.3) years old]. 117 cases of atrial septum defect were secondary foramen and 1 case was residual shunt after repair of atrial septum defect by transthoracic echocardiography. The patients with tricuspid insufficiency and pulmonary hypertension were followed up by transesophageal echocardiography.Results:The transcatheter closure of atrial septum defect(ASD) was successfully performed in 114 patients. 3 patients were successfully treated with right fourth intercostal small incision atrial defect occlusion due to the coaxial problem of occlusive device and atrial defect. One patient underwent repair of atrial septum defect during the correction of right ventricular injury. The selected size of occluder ranged from 12 mm to 38 mm. One case of ethmoidal orifice was successfully blocked with double occlusive device. There was no occlusive device displacement, no obvious residual shunt, peripheral vascular injury and other complications occurred in successful occlusive patients. 110 patients were directly transferred back to the general ward after extubation. The postoperative hospital stay was(2.3±1.1) days and the total hospitalization time was(4.5±1.7) days. There were 7 patients with tricuspid regurgitation above mild to moderate before operation, and 6 patients with tricuspid regurgitation decreased to mild regurgitation after occlusion. One month after operation, the pulmonary artery pressure of 51 patients with moderate and severe pulmonary hypertension decreased from(50.4±11.4)mmHg to(38.9±12.9) mmHg( P<0.05). The occlusive device was well fixed and no residual shunt was found. Conclusion:Transesophageal echocardiography guided transcatheter closure of atrial septum defect is not only safe and effective in adult cardiac surgery, but also can avoid radiation and contrast agent injury.
