RESUMO
BACKGROUND: This study was designed to develop a combined radiomics nomogram to preoperatively predict the risk categorization of thymomas based on contrast-enhanced computed tomography (CE-CT) images. MATERIALS: The clinical and CT data of 178 patients with thymoma (100 patients with low-risk thymomas and 78 patients with high-risk thymomas) collected in our hospital from March 2018 to July 2023 were retrospectively analyzed. The patients were randomly divided into a training set (n = 125) and a validation set (n = 53) in a 7:3 ratio. Qualitative radiological features were recorded, including (a) tumor diameter, (b) location, (c) shape, (d) capsule integrity, (e) calcification, (f) necrosis, (g) fatty infiltration, (h) lymphadenopathy, and (i) enhanced CT value. Radiomics features were extracted from each CE-CT volume of interest (VOI), and the least absolute shrinkage and selection operator (LASSO) algorithm was performed to select the optimal discriminative ones. A combined radiomics nomogram was further established based on the clinical factors and radiomics scores. The differentiating efficacy was determined using receiver operating characteristic (ROC) analysis. RESULTS: Only one clinical factor (incomplete capsule) and seven radiomics features were found to be independent predictors and were used to establish the radiomics nomogram. In differentiating low-risk thymomas (types A, AB, and B1) from high-risk ones (types B2 and B3), the nomogram demonstrated better diagnostic efficacy than any single model, with the respective area under the curve (AUC), accuracy, sensitivity, and specificity of 0.974, 0.921, 0.962 and 0.900 in the training cohort, 0.960, 0.892, 0923 and 0.897 in the validation cohort, respectively. The calibration curve showed good agreement between the prediction probability and actual clinical findings. CONCLUSIONS: The nomogram incorporating clinical factors and radiomics features provides additional value in differentiating the risk categorization of thymomas, which could potentially be useful in clinical practice for planning personalized treatment strategies.

BACKGROUND AND OBJECTIVES: The efficacy and safety of video-assisted thoracoscopic surgery (VATS) versus open thoracotomy in the treatment of non-small cell lung cancer (NSCLC) were evaluated with a focus on mediastinal lymph node dissection, postoperative recovery, and longterm outcomes including survival rates and disease-free intervals. Materials and Methods: This retrospective study analyzed data from 228 NSCLC patients treated at the Institute of Oncology Bucharest from 2016 to 2022. Both VATS and open surgical approaches were compared, with variables including demographic data, comorbidities, surgical outcomes, and postoperative complications meticulously recorded. Statistical significance was assessed using chi-square and independent samples t-tests. Results: Among the findings, VATS demonstrated significantly better two-year progression-free survival rates for patients in early stages (Stages 1-3) of NSCLC compared to open surgery, with p-values 0.01 and 0.001, respectively. In contrast, no significant difference was observed in Stage 4. Furthermore, VATS resulted in shorter operative times (mean 299 vs. 347 minutes, p 0.001), less estimated blood loss (98.68 mL vs. 160.88 mL, p 0.001), reduced chest tube duration (5.78 days vs. 12.17 days, p 0.001), and decreased hospital stays (12.0 days vs. 27.7 days, p 0.001). Conclusions: VATS is associated with improved long-term disease-free survival for early-stage NSCLC and more favorable short-term surgical outcomes, highlighting its advantages over open thoracotomy. Despite its benefits, VATS did not significantly reduce postoperative complications compared to open surgery.

BACKGROUND: Myelolipoma is an uncommon benign tumor composed of mature adipose tissue and hematopoietic elements. These tumors generally affect the adrenal glands, with anomalous presentations being rare and with few cases described in the literature. Most myelolipomas are asymptomatic and discovered incidentally, either through imaging tests or at autopsies. However, depending on the location and size of the lesion, myelolipomas can cause symptoms of mass effect. This article aims to report a very rare presentation of a symptomatic primary myelolipoma affecting the ribs. CASE PRESENTATION: A 21-year-old white female patient presented with a complaint of burning chest pain over 3 months, with gradual worsening in intensity, accompanied by a progressively growing bulge in the right thoracic wall. The patient underwent thoracotomy of the fifth and sixth ribs with complete excision of the lesion with a safety margin. Thoracic wall reconstruction was performed using a polypropylene mesh. The patient had a good postoperative course and was discharged on postoperative day 3. Histopathological examination revealed a histological image consistent with myelolipoma. CONCLUSIONS: This report underscores the importance of considering a myelolipoma diagnosis for tumor masses in the ribs.

Severe thoracic trauma can occur as a penetrating or blunt mono-injury or as part of a polytrauma. Almost half of all severely injured patients documented in the TraumaRegister DGU were diagnosed with severe chest trauma, defined according to the Abbreviated Injury Scale (AIS) as ≥ 3. In our own collective, the proportion was even higher with 60%. Emergency surgical treatment with a thoracotomy within the Trauma Resuscitation Unit or within the first hour of admission is an extremely rare intervention in Germany, accounting for 0.9% of severe thoracic injuries. The management of complex polytraumas and extensive pathophysiological reactions to the trauma, as well as knowledge about the development of secondary damage have led to the conclusion that minimally invasive procedures such as video-assisted thoracoscopy (VATS) or inserting a chest drain can resolve most severe thoracic injuries. At < 4%, penetrating injuries to the thorax are a rarity. Among blunt thoracic injuries, > 6% show an unstable thoracic wall that requires surgical reconstruction. The demographic development in Germany leads to a shift in injury pattern. Low-energy trauma results have lower incidence than higher-grade chest wall injuries with penetrating rib fractures in the pleura, lungs, peri-/myocardium and diaphragm. Sometimes this results in instability of the chest wall with severe restriction of respiratory mechanics, which leads to fulminant pneumonia and even ARDS (Acute Respiratory Distress Syndrome). With this background, surgical chest wall reconstruction has become increasingly important over the past decade. Together with the underlying strong evidence, the assessment of the extend and severity of the trauma and the degree of respiratory impairment are the basis for a structured decision on a non-surgical or surgical-reconstructive strategy, as well as the timing, type and extent of surgery. Early surgery within 72 hours can reduce morbidity (pneumonia rate, duration of intensive care and ventilation) and mortality. In the following article, evidence-based algorithms for surgical and non-operative strategies are discussed in the context on the management of severe thoracic injuries. Thus, a selective literature search was carried out for the leading publications on indications, treatment strategy and therapy recommendations for severe thoracic injury, chest wall reconstruction.

PURPOSE: This study aimed to clarify surgical complications associated with open surgery for congenital diaphragmatic hernia (CDH). METHODS: We performed an exploratory data analysis of the clinical characteristics of surgical complications of neonates with CDH who underwent laparotomy or thoracotomy between 2006 and 2021. Data of these patients were obtained from the database of the Japanese CDH Study Group. RESULTS: Among 1,111 neonates with left or right CDH, 852 underwent open surgery (laparotomy or thoracotomy). Of these 852 neonates, 51 had the following surgical complications: organ injury (n = 48; 6% of open surgeries); circulatory failure caused by changes in the organ location (n = 2); and skin burns (n = 1). Injured organs included the spleen (n = 30; 62% of organ injuries), liver (n = 7), lungs (n = 4), intestine (n = 4), adrenal gland (n = 2), and thoracic wall (n = 2). Fourteen of the patients who experienced organ injury required a blood transfusion (2% of open surgeries). The adjusted odds ratio of splenic injury for patients with non-direct closure of the diaphragm was 2.2 (95% confidence interval, 1.1-4.9). CONCLUSION: Of the patients who underwent open surgery for CDH, 2% experienced organ injury that required a blood transfusion. Non-direct closure of the diaphragmatic defect was a risk factor for splenic injury.

National trends show rapid increases in the use of mechanical circulatory support devices (MCSD) over the last 20 years. While current literature has not proven a mortality benefit in cardiogenic shock as a complication of acute myocardial infarction (AMI-CS) with percutaneous MCSD, these devices are vital to maximizing cardiopulmonary parameters for definitive therapy. To minimize complications, many different techniques have been described including a novel off-pump direct apical cannulation for venoarterial-extracorporeal membrane oxygenation (VA-ECMO). This technique allows early ambulation and avoids peripheral artery access complications but has only been described in small case series. Our case series represents the largest summary of patients (50) using this technique and contains the only comparison data to date. Fifty-four percentage of our patients were Society for Cardiovascular Angiography and Interventions (SCAI) stage D and 22% were arrested before cannulation. We achieved flows on average >5 L/min and most patients required biventricular drainage (86%) and an oxygenator (92%). Thirty day survival was 56% and most survivors were bridged to heart transplant (30%). Our most common complication was bleeding (16%). This technique showed significant improvement in ejection fraction (EF), cardiac output/index (CO/CI), and pulmonary artery pressures. This case series demonstrates the safety and efficacy of this novel technique for central cannulation in cardiogenic shock at large scale within a single institution.

INTRODUCTION: Pulmonary regurgitation (PR) remains a common sequela in patients following surgically corrected TOF, and may lead to progressive right ventricle dilatation and dysfunction. The conventional approach of redo-sternotomy for pulmonary valve replacement (PVR) is associated with increased operative time as well as risks of bleeding and injury to the heart and great vessels. Thus, left anterior mini-thoracotomy has become an alternative approach in eliminating the risks of redo-sternotomy in these patients. This series aimed to determine the outcomes of minimally invasive pulmonary valve replacement after surgical TOF correction. METHODS: A retrospective analysis was conducted on 24 patients with severe PR post-surgical TOF correction who underwent left anterior mini-thoracotomy PVR in Penang General Hospital from January 2021 to January 2023. RESULTS: The median age was 23.5 years (I.Q.range 17.6-36.3), with a male:female ratio of 1:4. Majority of patients had mild to moderate symptoms prior to surgery and 19 patients (79.1%) were on regular diuretics medication. All patients had severe free-flow PR with evidence of right ventricular dilatation and dysfunction. Magnetic Resonance Imaging and computed tomography of pulmonary artery were performed prior to surgery. Minimally invasive PVR was performed on all patients via left upper anterior mini-thoracotomy and femoral-femoral bypass without cardioplegic arrest. The operative time and cardiopulmonary bypass time were 208 (I.Q.range 172-324) and 98.6 minutes(I.Q.range 87.4-152.4) respectively. The time to wean off inotropes postoperatively was 6.2 hours (I.Q.range1.4-14.8), and no postoperative arrhythmia and chest re-exploration were reported. Most patients stayed in Intensive Care Unit (ICU) for 10.8 hours (I.Q.range 8.4-36.5), and the total hospital stay was 4.2 days (I.Q.range 3.4-7.6). 2 patients (11.1%) required blood transfusion postoperative. There was no paravalvular leak and no mortality during the follow-up period of up to 28 months. CONCLUSION: Minimally invasive PVR after surgical correction of TOF is a safe alternative to the conventional redo-sternotomy approach in patients with favorable anatomy. This approach is able to reduce the risks associated with redo-sternotomy, particularly bleeding and injury to mediastinal structures, with the additional benefit of expedited recovery and hospital discharge. Our series has shown a safe and efficient approach in these patients with favorable outcomes.

Minimally invasive coronary surgery offers benefits to the patient. Besides the anterior wall, the lateral and inferior walls can be reached through a small thoracotomy with off-pump techniques. Thoracoscopic coronary identification can be very useful in these multivessel procedures. Positioning the heart without cardiopulmonary bypass can be challenging. We describe our technique for off-pump positioning and for grafting the right posterior descending coronary artery.

This study elucidates the efficacy and outcomes of a minimally invasive aortic valve replacement via a right anterior mini-thoracotomy, emphasizing its potential to minimize surgical trauma and expedite recovery while maintaining procedural integrity comparable to that of a traditional full sternotomy. This video tutorial demonstrates a successful aortic valve replacement procedure using the right anterior mini-thoracotomy approach, characterized by the absence of sutureless valves and specialized instruments. The detailed surgical procedure includes specific steps to optimize visibility and access through strategic incisions and rib dislocations, adhering to "the box principle" for effective exposure of the aortic valve. This video tutorial suggests that a right anterior mini-thoracotomy is a viable, cost-effective alternative to a conventional sternotomy for aortic valve replacement, offering significant patient benefits without compromising long-term valve function or safety. The broader implications for patient selection and surgical techniques highlight the need for meticulous preoperative planning and anatomical assessment to maximize the potential of a right anterior mini-thoracotomy in clinical practice.

INTRODUCTION: Thoracotomy procedures can result in significant pain and cause nausea/vomiting. Glucocorticoids have anti-emetic and analgesic effects due to their anti-inflammatory and nerve-blocking properties. This study investigates the additive effect of local dexamethasone with bupivacaine as sole analgesic medication through a peripleural catheter after thoracotomy. METHOD: The study was conducted as a randomized control trial on 82 patients. Participants were allocated to receive either 2.5 mg/kg of bupivacaine plus 0.2 mg/kg of dexamethasone or 2.5 mg/kg of bupivacaine plus the same amount of normal saline as placebo through a 6 French peripleural catheter implemented above the parietal pleura and beneath the musculoskeletal structure of the chest wall. The primary outcome was the severity of pain 24 h after the operation in the visual analogue scale (VAS) score. Secondary outcomes were the incidence of nausea/vomiting, opioid consumption for pain control, and incidence of any adverse effects. RESULTS: A total of 50 participants were randomized to each group, and the baseline characteristics were similar between the groups. Median of VAS score (6 (3-8) vs. 8 (6-9), p < 0.001), postoperative opioid consumption (9 (36%) vs. 17 (68%) patients, p=0.024), and median length of hospital stay (4 (3-8) vs. 6 (3-12) days, p < 0.001) were significantly lower in the dexamethasone group. However, postoperative nausea/vomiting (p=0.26 for nausea and p=0.71 for vomiting) and surgical site infection (p = 0.55) were similar between the two groups. CONCLUSION: In thoracotomy patients, administering local dexamethasone + bupivacaine through a peripleural catheter can reduce postoperative pain, analgesic consumption, and length of hospital stay.

We demonstrated successful treatment of patients with complicated central lung cancer, who underwent right upper sleeve lobectomy with carinal resection. We have used the following options for carinal reconstruction: anastomosis of trachea with the left main bronchus and anastomosis of intermediate bronchus with the left main bronchus (clinical case No. 1) or with trachea (clinical case No. 2). Cervicothoracotomy provided correct N-staging and mobilization of trachea with left main bronchus. This approach provided compliance with oncological principles of surgical treatment of lung cancer and significantly reduced tension of anastomosis. These aspects are important for satisfactory immediate functional and oncological results after right upper sleeve lobectomy with carinal resection.

ABSTRACT: With the advancements in regional anesthesia and ultrasound techniques, the use of non-neuraxial blocks like the erector spinae plane block (ESPB) has been increasing in cardiac surgeries with promising outcomes. A total of 3,264 articles were identified through a literature search. Intervention was defined as ESPB. Comparators were no regional technique performed or sham blocks. Four studies with a total of 226 patients were included. Postoperative opioid consumption was lower in the group that received ESPB than the group that did not (weighted mean difference [WMD]: -204.08; 95% CI: -239.98 to -168.19; P < 0.00001). Intraoperative opioid consumption did not differ between the two groups (WMD: -398.14; 95% CI: -812.17 to 15.98; P = 0.06). Pain scores at 0 hours were lower in the group that received ESPB than the group that did not (WMD: -1.27; 95% CI: -1.99 to -0.56; P = 0.0005). Pain scores did not differ between the two groups at 4-6 hours (WMD: -0.79; 95% CI: -1.70 to 0.13; P = 0.09) and 12 hours (WMD: -0.83; 95% CI: -1.82 to 0.16; P = 0.10). Duration of mechanical ventilation in minutes was lower in the group that received ESPB than the group that did not (WMD: -45.12; 95% CI: -68.82 to -21.43; P = 0.0002). Given the limited number of studies and the substantial heterogeneity of measured outcomes and interventions, further studies are required to assess the benefit of ESPB in midline sternotomies.

Aortic valve replacement (AVR) is a critical procedure for patients with aortic valve diseases. This study compares the effectiveness of three minimally-invasive surgical approaches for AVR: totally thoracoscopic (TT), right anterior mini-thoracotomy, and upper mini-sternotomy. We analyzed retrospective data from 130 patients who underwent one of these surgeries, focusing on various factors such as duration of hospital stay, operation time, times for cardiopulmonary bypass and aortic cross-clamping, postoperative complications, levels of cardiac biomarkers, pain intensity using the Visual Analog Scale, and mid-term survival rates. Results show that while the TT method had the longest operation times, it also had the shortest hospital stays and faster pain reduction post-surgery. Although the TT group initially showed higher cardiac biomarker levels after surgery, these levels normalized by the third day, similar to the other groups. There were no significant differences in mid-term survival and major adverse cardiac and cerebrovascular event (MACCE) rates among the groups. These findings suggest that the TT method, despite longer surgical times, offers a quicker initial recovery, making it a viable option for AVR.

OBJECTIVES: Minimally invasive cardiac surgery techniques are increasingly used but have longer cardiopulmonary bypass time, which may increase inflammatory response and negatively affect coagulation. Our aim was to compare biomarkers of inflammation and coagulation as well as transfusion rates after minimally invasive mitral valve repair and mitral valve surgery using conventional sternotomy. DESIGN: A prospective non-randomized study was performed enrolling 71 patients undergoing mitral valve surgery (35 right mini-thoracotomy and 36 conventional sternotomy procedures). Blood samples were collected pre- and postoperatively to assess inflammatory response. Thromboelastometry (ROTEM) was performed to assess coagulation, and transfusion rates were monitored. RESULTS: The minimally invasive group had longer cardiopulmonary bypass times compared to the sternotomy group: 127 min ([115-146] vs 79 min [65-112], p < 0.001) and were cooled to a lower temperature during cardiopulmonary bypass, 34 °C vs 36 °C (p = 0.04). IL-6 was lower in the minimally invasive group compared to the conventional sternotomy group when measured at the end of the surgical procedure, (38 [23-69] vs 61[41-139], p = 0.008), but no differences were found at postoperative day 1 or postoperative day 3. The transfusion rate was lower in the minimally invasive group (14%) compared to full sternotomy (35%, p = 0.04) and the chest tube output was reduced, (395 ml [190-705] vs 570 ml [400-1040], p = 0.04). CONCLUSIONS: Our data showed that despite the longer use of extra corporal circulation during surgery, minimally invasive mitral valve repair is associated with reduced inflammatory response, lower rates of transfusion, and reduced chest tube output.

Surgical treatment of chondromyxoid fibroma of ribs is described. The diagnosis was verified after histological analysis. The patient underwent resection of multinodular tumor of anterolateral thoracic wall invading abdominal cavity via thoracoabdominal access. Postoperative period was uneventful. This case demonstrates the need for total en-bloc resection of tumor with surrounding tissues. Surgery is the only effective method for these patients.

BACKGROUND: The incidence of minimally invasive heart surgery via mini-thoracotomy (MT; right anterior thoracotomy) is on the rise, accompanied by an increase in post-MT intercostal nerve neuralgia and the risk of lung herniation through the incision site. While various methods have been proposed to address these issues, none have been commonly effective. In this case report, we attempted to simultaneously address these problems by performing intercostal cryoablation (IC) and mesh repair. CASE PRESENTATION: A 43-year-old male was referred to our hospital for chronic post-thoracotomy neuralgia following heart surgery via MT, involving patch closure of an atrial septal defect and tricuspid annuloplasty. He presented with intercostal nerve neuralgia and lung herniation accompanied by severe pain. Despite medication and lidocaine injections, there was no relief. Consequently, he underwent surgical treatment with IC for chronic MT wound pain and simultaneously underwent mesh repair for a lung hernia. He was discharged from hospital free of complications. Subsequently, he no longer required further pain medication and experienced a favorable recovery. CONCLUSION: Our findings suggest that concurrent IC and mesh repair can effectively relieve chronic post-MT intercostal nerve neuralgia and severe lung herniation pain in patients who underwent MT surgery, leading to a decrease in opioid medication usage.

BACKGROUND: A left thoracotomy approach is anatomically appropriate for childhood aortic coarctation; however, the pediatric femoral arteriovenous diameters are too small for cardiopulmonary bypass cannulation. We aimed to determine the safety of a partial cardiopulmonary bypass through the main pulmonary artery and the descending aorta in pediatric aortic coarctation repair. METHODS: We retrospectively reviewed 10 patients who underwent coarctation repair under partial main pulmonary artery-to-descending aorta cardiopulmonary bypass with a left thoracotomy as the CPB group. During the same period, 16 cases of simple coarctation of the aorta repair, with end-to-end anastomosis through a left thoracotomy without partial CPB assistance, were included as the non-CPB group to evaluate the impact of partial CPB. RESULTS: The median age and weight at surgery of the CPB group were 3.1 years (range, 9 days to 17.9 years) and 14.0 (range, 2.8-40.7) kg, respectively. Indications for the partial cardiopulmonary bypass with overlap were as follows: age > 1 year (n = 7), mild aortic coarctation (n = 3), and predicted ischemic time > 30 min (n = 5). Coarctation repair using autologous tissue was performed in seven cases and graft replacement in three. The mean partial cardiopulmonary bypass time, descending aortic clamp time, and cardiopulmonary bypass flow rate were 73 ± 37 min, 57 ± 27 min, and 1.6 ± 0.2 L/min/m2, respectively. Urine output during descending aortic clamping was observed in most cases in the CPB group (mean: 9.1 ± 7.9 mL/kg/h), and the total intraoperative urine output was 3.2 ± 2.7 mL/kg/h and 1.2 ± 1.5 mL/kg/h in the CPB and non-CPB group, respectively (p = 0.020). The median ventilation time was 1 day (range, 0-15), and the intensive care unit stay duration was 4 days (range, 1-16) with no surgical deaths. No major complications, including paraplegia or recurrent coarctation, occurred postoperatively during a median observation period of 8.1 (range, 3.4-17.5) years in the CPB group. In contrast, reoperation with recurrent coarctation was observed in 2 cases in the non-CPB group (p = 0.37). CONCLUSIONS: Partial cardiopulmonary bypass through the main pulmonary artery and descending aorta via a left thoracotomy is a safe and useful option for aortic coarctation repair in children.

BACKGROUND: Osteosarcoma is the most common primary malignant bone tumour in children and adolescents. Lungs are the most frequent and often the only site of metastatic disease. The presence of pulmonary metastases is a significant unfavourable prognostic factor. Thoracotomy is strongly recommended in these patients, while computed tomography (CT) remains the gold imaging standard. The purpose of our study was to create tools for the CT-based qualification for thoracotomy in osteosarcoma patients in order to reduce the rate of useless thoracotomies. METHODS: Sixty-four osteosarcoma paediatric patients suspected of lung metastases on CT and their first-time thoracotomies (n = 100) were included in this retrospective analysis. All CT scans were analysed using a compartmental evaluation method based on the number and size of nodules. Calcification and location of lung lesions were also analysed. Inter-observer reliability between two experienced radiologists was assessed. The CT findings were then correlated with the histopathological results of thoracotomies. Various multivariate predictive models (logistic regression, classification tree and random forest) were built and predictors of lung metastases were identified. RESULTS: All applied models proved that calcified nodules on the preoperative CT scan best predict the presence of pulmonary metastases. The rating of the operated lung on the preoperative CT scan, dependent on the number and size of nodules, and the total number of nodules on this scan were also found to be important predictors. All three models achieved a relatively high sensitivity (72-92%), positive predictive value (81-90%) and accuracy (74-79%). The positive predictive value of each model was higher than of the qualification for thoracotomy performed at the time of treatment. Inter-observer reliability was at least substantial for qualitative variables and excellent for quantitative variables. CONCLUSIONS: The multivariate models built and tested in our study may be useful in the qualification of osteosarcoma patients for metastasectomy through thoracotomy and may contribute to reducing the rate of unnecessary invasive procedures in the future.

Upper hemi-sternotomy is a common approach for outflow graft anastomosis to the ascending aorta in minimally invasive left-ventricular assist device implantation. Right mini-thoracotomy may also be used, but use of robotic assistance has been reported only anecdotally. The aim of our study was to confirm the feasibility of robotically assisted suturing of the outflow graft anastomosis and to assess performance metrics for the robotic suturing part of the procedure. The procedure was carried out in eight cadaver studies by two surgeons. The assist device pump head was inserted through a left-sided mini-thoracotomy and the outflow graft was passed toward a right-sided second interspace mini-thoracotomy through the pericardium. After placement of a partial occlusion clamp on the ascending aorta, a longitudinal aortotomy was performed and the outflow graft to ascending aorta anastomosis was carried out robotically. The procedure was feasible in all eight attempts. The mean outflow graft anastomotic time was 20.1 (SD 6.8) min and the mean surgeon confidence and comfort levels to complete the anastomoses were 8.3 (SD 2.4) and 6.9 (SD2.2), respectively, on a ten-grade Likert scale. On open inspection of the anastomoses, there was good suture alignment in all cases. We conclude that suturing of a left-ventricular assist device outflow graft to the human ascending aorta is very feasible with good surgeon comfort. Anastomotic times are acceptable and suture placement can be performed with appropriate alignment.
