Transfusions and early outcomes in anaemic patients undergoing off- or on-pump coronary artery bypass grafting
Koster A, Zittermann A, Gummert JF, von Dossow V and Deutsch MA
We retrospectively compared transfusion rates and early outcomes in 1621 consecutive patients with preoperative anaemia undergoing off-pump coronary artery bypass grafting (OPCAB) or on-pump coronary artery bypass grafting (ONCAB) surgery using a propensity score analysis with inverse probability of treatment weighting. Endpoints were transfusions, early morbidity, and mortality. Surgeries were performed by 45 dedicated OPCAB and/or ONCAB surgeons during the 10-year study period. Operative data did not differ significantly between study groups with the exception of a more frequent use of bilateral internal mammary artery revascularization approach in OPCAB patients than ONCAB patients. OPCAB was associated with fewer transfusions and lower risk for the need of postoperative renal replacement therapy, but higher risk of wound infections than ONCAB. Perioperative stroke risk and 30-day and 1-year mortality did not differ significantly between the groups. Our data in a 'real-world setting' indicate that in patients with preoperative anaemia both ONCAB and OPCAB are feasible surgical approaches regarding early morbidity and mortality.
Successful management of complex haemorrhagic pericardial cyst with cirrhosis of liver: a case report
Lykins AJ, Garg P, Fleissner ZJ and Sareyyupoglu B
Haemorrhagic pericardial cysts are rare and may be complicated by encasement of the heart, right heart failure and, rarely, cardiac cirrhosis. Surgical management of complicated cysts is challenging and has poor outcomes. We report a case of successful surgical management of a complicated pericardial cyst presenting with cardiac cirrhosis and the challenges associated with this condition.
Surgical management of cardiac cystic echinococcosis in a paediatric patient: a case report
Biçer M, Kozan Ş, Altın HF and Aydemir NA
Cystic echinococcosis, a zoonotic parasitic disease, is endemic to many countries worldwide. This slowly progressing disease is seen rarely in the paediatric age group. In terms of cyst localization, cardiac involvement is infrequent. We report the case of a successful surgical and medical management of a paediatric hydatid disease patient with involvement of the heart.
Does the division of the inferior pulmonary ligament in upper lobectomy result in improved short-term clinical outcomes and long-term survival?
Wang YF, Deng HY, Huang W and Zhou Q
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'Does the division of the inferior pulmonary ligament (IPL) in upper lobectomy result in improved short-term clinical outcomes and long-term survival?'. Altogether 43 papers were found using the reported search, of which 6 studies represented the best evidence to answer the clinical question, including a previous best evidence topic study, a meta-analysis and 4 retrospective cohort studies. The author, journal, date and country of publication, patient group studied, study type and relevant outcomes and results of these papers are tabulated. Most of the enrolled studies reported that there is no significant difference between the division groups and the preservation groups in terms of drainage time, drainage volume, postoperative dead space and complications. While 3 cohort studies revealed unfavoured postoperative pulmonary function in the division groups, including lung volume, forced vital capacity and forced expiratory volume in 1 s. The previous meta-analysis and a recent cohort study also found that the division of IPL might lead to increased bronchus angle change or torsion. Moreover, 2 cohort studies found that the division of IPL could not improve the long-term survival of patients undergoing upper lobectomy. Current evidence showed that dividing the IPL could not result in clinical benefits but might lead to decreased pulmonary function instead. Therefore, we recommended not dissecting the IPL routinely during upper lobectomy.
Postoperative aortic injury caused by a staple line formed during wedge resection of the lung
Yamaji M, Yano M, Okamaoto S and Fukui T
We report a case of aortic perforation caused by the staple line formed during a wedge resection for lung cancer. Six hours after an uneventful wedge resection, sudden frank drainage of blood from the chest tube occurred. A reoperation was performed, and we found bleeding from the aorta. After suturing the bleeding spot on the aorta, we found that the stapling line of the lung rode on the aorta with longitudinal contact. We speculated that the stapling line scratched the aorta in synchrony with the patient's breathing and injured the aorta.

Seong YW, Chai YJ, Lee JM, Ok YJ, Oh SJ, Choi JS and Moon HJ
We investigated the safety and efficacy of continuous intraoperative neuromonitoring (CIONM) during video-assisted thoracoscopic lobectomy for left lung cancer in preventing recurrent laryngeal nerve injury.
Retraction: Virtual reality-guided aortic valve leaflet reconstruction for type 0 bicuspid aortic stenosis
Is video-assisted thoracoscopic surgery comparable with thoracotomy in perioperative and long-term survival outcomes for non-small-cell lung cancer after neoadjuvant treatment?
Wang YF, Deng HY, Huang W and Zhou Q
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'Is video-assisted thoracoscopic surgery comparable with thoracotomy in perioperative and long-term survival outcomes for patients with non-small cell lung cancer following neoadjuvant therapy intended for anatomical lung resection?'. Altogether 655 papers were found using the reported search, of which 12 studies represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type and relevant outcomes and results of these papers are tabulated. Almost all of the enrolled cohort studies reported that video-assisted thoracoscopic surgery (VATS) was comparable with thoracotomy in negative surgical margin rate, postoperative mortality, complication rate, overall survival and disease-free survival. Moreover, 7 studies found patients in the VATS group had a significantly shorter hospital stay. Furthermore, in these well-matched cohort studies (6 studies), it still held true that VATS was comparable with thoracotomy in long-term prognosis with enhanced recovery. However, the issue regarding surgical radicality and intraoperative conversion to thoracotomy still should be noted carefully among these patients receiving VATS surgery because all the current available evidence was retrospective based on relatively small sample sizes. Nevertheless, thoracic surgeons should not consider VATS inferior to thoracotomy for patients after neoadjuvant treatment. VATS surgery could be an alternative for selected patients with locally advanced but relatively small, peripheral, fewer positive N2 lymph nodes and non-squamous NSCLC intended for anatomic lung resection.
Local tumour residue after microwave ablation for lung cancer: a case report
Liu G, Gu M, Wang X and He J
Thermal ablation has become a novel method for the treatment of pulmonary nodules, but the short-time evaluation of the ablation effect is mainly based on computed tomography images. We report a case of local tumour residue after microwave ablation, which was confirmed by pathology after lobectomy. This case alerts us that thermal ablation should not be the preferred treatment for operable pulmonary nodules.
Delayed bowel necrosis due to inferior mesenteric artery occlusion in Stanford type A acute aortic dissection
Kawaguchi Y, Fukumoto Y, Tamaki M and Kitamura H
Although inferior mesenteric artery occlusion due to acute aortic dissection sometimes occurs, it is usually not considered an important finding. Herein, we present an extremely rare case of delayed bowel ischaemia due to inferior mesenteric artery occlusion in Stanford type A acute aortic dissection that highlights the need for cardiac surgeons to be mindful of inferior mesenteric artery occlusion in patients with superior mesenteric artery dissection or vascular anomalies in the mesenteric arteries.

Kirov H, Caldonazo T, Audisio K, Rahouma M, Robinson NB, Cancelli G, Soletti GJ, Demetres M, Ibrahim M, Faerber G, Gaudino M and Doenst T
The aim of this study was to perform a meta-analysis of studies reporting outcomes in patients with liver dysfunction addressed by the model of end-stage liver disease and Child-Turcotte-Pugh scores undergoing cardiac surgery.
Congenital aortocaval fistula combined with patent ductus arteriosus in an infant: a case report
Jiao X, Zhao L, Wu Y and Chen S
Congenital aortocaval fistula (ACF) is a rare cardiac malformation. While it can occur in combination with patent ductus arteriosus (PDA), this has not been reported. In this case, a 1-year-old infant had a heart murmur found in a routine physical examination, and PDA was revealed by transthoracic echocardiography and abdominal ACF was detected by three-dimensional coronary artery computed tomography. Percutaneous interventional therapy, used for ACF and PDA, was performed to occlude the malformation. The patient presented good health without any discomfort at a 1-year follow-up. The percutaneous closure of ACF and PDA with an Amplatzer vascular device can be considered an appropriate option.
Balancing quality and quaternary care imperative using a high-risk case review committee in adults
Ibrahim M, Acker A, Weiss S, Lawrence K, Ottemiller S, McGarvey J, Epler M, Williams M, Szeto WY and Acker M
Quaternary care centres have an imperative to serve as hospitals of last resort and must also meet professional quality targets. We developed a high-risk committee (HRC) to evaluate cases meeting pre-defined predicted risk cut-offs as a part of an overall quality improvement drive.
Bovine pericardial patch repair for abdominal aortic pseudoaneurysm to preserve lumbar arteries
Nabeshima J, Mizuno T and Nagaoka E
We describe a case of aortic repair using bovine pericardium for a pseudoaneurysm of a dissecting abdominal aorta. A 71-year-old man had undergone several aortic replacement surgeries for type B aortic dissection. He developed paraparesis after thoraco-abdominal aortic surgery and recovered. After 3 years, the scheduled computed tomography scan showed a pseudoaneurysm of the dissecting abdominal aorta. Because he was at high risk of spinal cord ischaemia, aortic repair using bovine pericardium was performed, and all lumbar arteries were preserved. During the 12-month follow-up, he was asymptomatic, and computed tomography scans showed no dilation of the aorta.
Unravelling early sinus node dysfunction after pediatric cardiac surgery: a pre-existing arrhythmogenic substrate
Ramdat Misier NL, Taverne YJHJ, van Schie MS, Kharbanda RK, van Leeuwen WJ, Kammeraad JAE, Bogers AJJC and de Groot NMS
Early post-operative sinus node dysfunction (SND) is common in paediatric patients undergoing surgical correction of congenital heart defects (CHD). At present, the pathophysiology of these arrhythmias is incompletely understood. In this case series, we present three paediatric patients in whom we performed intraoperative epicardial mapping and who developed early post-operative SND. All patients had either an inferior or multiple sinoatrial node (SAN) exit sites, in addition to extensive conduction disorders at superior and inferior right atrium. Our findings contribute to the hypothesis that pre-existing alterations in SAN exit sites in combination with atrial conduction disorders may predispose paediatric patients with CHD for early post-operative SND. Such insights in the development of arrhythmias are crucial as it may be the first step in identifying high-risk patients.

The aim was to report mid-term performance of decellularized equine pericardium used for repair of various congenital heart defects in the pediatric population.
Different calcification patterns of tricuspid and bicuspid aortic valves and their clinical impact
Gollmann-Tepeköylü C, Nägele F, Engler C, Stoessel L, Zellmer B, Graber M, Hirsch J, Pölzl L, Ruttmann E, Tancevski I, Tiller C, Barbieri F, Stastny L, Reinstadler SJ, Oezpeker UC, Semsroth S, Bonaros N, Grimm M, Feuchtner G and Holfeld J
Mechanical strain plays a major role in the development of aortic calcification. We hypothesized that (i) valvular calcifications are most pronounced at the localizations subjected to the highest mechanical strain and (ii) calcification patterns are different in patients with bicuspid and tricuspid aortic valves.
