OBJECTIVES: A novel surgical strategy using haemodynamic analyses based on virtual operations with computational simulations has been introduced for complicated pulmonary stenosis. We evaluated the efficacy of this strategy. METHODS: Six patients were enrolled. Before surgery, the optimal pulmonary arteries were constructed based on computational fluid dynamics using 3-dimensional computed tomography. Energy loss (EL, mW) and wall shear stress (WSS, Pa) were calculated...

OBJECTIVES: Our goal was to evaluate the impact of the discontinuation times of dual antiplatelet therapy with clopidogrel, prasugrel or ticagrelor on postoperative bleeding rates and the use of blood products in patients undergoing isolated urgent coronary artery bypass grafting (CABG). METHODS: We retrospectively analysed 334 patients with acute coronary syndrome undergoing urgent CABG at the University Hospital Basel. A total of 262 patients continued to take dual antiplatelet therapy during the surgery (72 received clopidogrel; 68, prasugrel; and 122, ticagrelor)...

OBJECTIVES: Typically, single-lung ex vivo lung perfusion (SL-EVLP) is preferred when there is concern of contamination from the opposite lung. However, a comprehensive assessment of the SL-EVLP has not been completed. The purpose of this study is to compare the physiological parameters of SL-EVLP and double-lung EVLP (DL-EVLP) in the assessment of transplant suitability. METHODS: Seven pairs of rejected donor lungs were perfused in cellular EVLP, with a tidal volume of 6 ml/kg ideal body weight and a perfusion flow of 70 ml/kg/min...

OBJECTIVES: The invention of new surgical procedures requires testing at different stages including animal models. To facilitate this process, we have developed a computer-controlled extracorporeal circulation system for testing of an explanted porcine heart simulating a variety of physiological parameters. Mitral valve function can be assessed before and after induced valve insufficiency and after valve repair. Accordingly, techniques and instruments can be modified at early stages of prototype development...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: In patients undergoing cardiac surgery, is postoperative music therapy effective in reducing pain and anxiety? Altogether, 153 papers were found using the reported search method, of which 7 represented the best evidence to answer the clinical question. Six of the included studies were randomized trials, with 1 further non-randomized trial. The specific music protocols utilized widely varied, ranging from 1 short session on day 1 postoperatively to multiple sessions per day over a 72-h period...

A 7-month-old boy with a complete atrioventricular septal defect presented with severe left atrioventricular valve regurgitation 4 months after complete repair. As the valve was unsuitable for the repair and the annulus was too small to accommodate a mechanical prosthesis, the modified mitral Ross operation was performed. The long-term outcome was uneventful for 12 years. The mitral Ross procedure is an old-described technique in which classically the pulmonary autograft is encased in a prosthetic conduit preventing any growth potential...

The isolated coronary sinus (CS) rupture causing cardiac tamponade following blunt chest trauma is a very rare and very unique traumatic form of cardiac tamponade. Prompt recognition of this injury is crucial for patient survival. CS injuries are frequently difficult to repair and are potentially lethal. A meticulous repair carried out on an arrested, empty and well-protected heart is recommended to achieve secure haemostasis and CS patency. To our knowledge, this is the first report on the successful repair of isolated CS rupture following blunt chest trauma...

OBJECTIVES: Stem cells secrete significant amounts of bioactive factors in their secretome that can be immunosuppressive. We studied the effect of the secretome obtained from bone marrow-derived mesenchymal stem cells (BMSC-sec) in combination with cyclosporine A following acute rejection of lung allografts in the rat. METHODS: Lung allotransplants were performed from male Brown Norway donor rats to recipient male Fisher 344 rats. Rat BMSC-sec was introduced intratracheally in the recipient every day after the transplant until the day the animal was sacrificed...

OBJECTIVES: Nonintubated surgical biopsy (NISB) of interstitial lung disease (ILD) has shown promise in unicentre reports as a reliable method to achieve pathological diagnosis with low morbidity. The aim of this study was to investigate for the first time early outcomes of NISB of ILD using a multicentre retrospective analysis. METHODS: Seven European and extra-European institutions participated in the study. Overall, 112 procedures were included. The mean age was 60 ± 12 years (65 men and 47 women)...

OBJECTIVES: The purpose of this study was to develop a score to predict the complexity of video-assisted thoracoscopic surgery (VATS) lobectomies preoperatively. METHODS: One hundred and thirty-nine consecutive patients undergoing VATS lobectomy operated on by a single surgeon as the first operator were included. Complex operations were defined as: operation time >180 min (corresponding to the 75th percentile) or a conversion to thoracotomy. Several patient-related baseline and radiological variables were tested for a possible association with surgical complexity by logistic regression analysis...

Sandro Botticelli was one of the most renowned artists of the 15th century. He was based in Florence during the flourishing of the Renaissance, a time when anatomical knowledge of ancient times was reclaimed through cadaveric dissection. This report proposes that such knowledge enabled Botticelli to enhance the iconography of his masterpieces, Madonna of the Pomegranate, by incorporating a concealed image of the heart and cardiac anatomy within it.

Only a handful of congenital aneurysms of the right atrium have been reported in the literature. They are most commonly found in the third decade of life, and the differential diagnosis depends on the patient's age profile. They are associated with 5% risk of sudden cardiac death. Once diagnosed, they should be surgically removed even in the absence of symptoms.

OBJECTIVES: In Siewert type I/II oesophageal adenocarcinoma, the sensitivity and specificity of computed tomography (CT), positron emission tomography (PET)-CT and endoscopic ultrasound (EUS) for assessment of the N descriptor in defined groups of lymph nodes were investigated. METHODS: CT, PET/CT, EUS images and the pathological data of 101 oesophageal adenocarcinomas submitted to primary resection were compared. The lymph nodes were identified as (a) right paratracheal/subcarinal/pulmonary ligament; (b) paraoesophageal; (c) paracardial; (d) left gastric artery, lesser curvature; (e) coeliac trunk, hepatic/splenic artery...

OBJECTIVES: A number of meta-analytical and database studies have sought to compare open, video-assisted thoracoscopic surgery (VATS) and robotic operative approaches to lobectomy, often with conflicting results. Our objective was to perform a comprehensive review of these meta-analytical and database studies published to date. METHODS: A systematic review was conducted in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines using the PubMed and Scopus databases...

Thoracic venous aneurysms are rare, and bleeding is possible. A 9-year-old female patient presented with a thoracic wall mass. No blood flow was observed in the mass, and a chronic expanding haematoma was suspected based on the differential diagnosis. However, the venous structure was identified in the wall of the mass on pathological examination, and the diagnosis of the venous aneurysm was thereby established. Because the venous aneurysm contains fresh blood and bleeding can be profuse when such lesions are not properly handled during a surgical procedure, making the visibility of the surgeon poor, the venous aneurysm must be included in the differential diagnosis...

OBJECTIVES: Our goal was to evaluate the influence of donor-related factors on the durability of pulmonary homografts (PHGs) for right ventricular outflow tract reconstruction of congenital heart defects. METHODS: Between 1990 and 2016, 223 PHGs were used in 197 patients for right ventricular outflow tract reconstruction. Long-term durability was investigated in relation to patient- and disease-specific as well as to donor-related factors, based on the PHG replacement rate...
