Comparative StudyDoes body mass index impact the early outcome of surgical revascularization? A comparison between off-pump and on-pump coronary artery bypass grafting.
To investigate the effects of body mass index (BMI) on early outcomes after revascularization using either on-pump or off-pump surgery. ⋯ Our study did not detect significant differences between BMI classes with regard to mortality and morbidity. However, a slight trend towards a steadily increasing short-term mortality was detectable for patients with higher BMI values. When comparing ONCAB versus OPCAB, patients with higher BMI values appeared to have a weak tendency towards a reduced short-term morbidity and mortality in favour of OPCAB.

Case ReportsCombined operative technique with anterior surgical approach and video-assisted thoracoscopic surgical lobectomy for anterior superior sulcus tumours.
Video-assisted thoracoscopic surgery (VATS) has been widely used, but surgical resections of superior sulcus tumours remain challenging because of their anatomical location. For such cases, less-invasive procedures, such as the anterior transcervical-thoracic and transmanubrial approaches, have been widely performed because of their excellent visualization of the subclavian vessels. Recently, a combined operative technique with an anterior surgical approach and VATS for anterior superior sulcus tumours has been introduced. ⋯ Subsequently, dissections of the anterior inlet of the tumours were performed using the transmanubrial approach in two patients and the anterior trans-cervical-thoracic approach in one patient. Both approaches provided excellent access to the anterior inlet of the tumour and exposure of the subclavian vessels, resulting in radical resection of the tumour with concomitant resection of the surrounding anatomical structures, including the chest wall and vessels. In conclusion, VATS lobectomy combined with the anterior surgical approach might be an excellent procedure for the resection of anterior superior sulcus tumours.

Evaluation of bilateral pulmonary artery banding for initial palliation in single-ventricle neonates and infants: risk factors for mortality before the bidirectional Glenn procedure.
Bilateral pulmonary artery banding is considered as 'first-stage' palliation for neonates who have hypoplastic left heart syndrome. This study aimed to identify risk factors that influence outcome before the bidirectional Glenn operation. ⋯ Postoperative atrioventricular valve regurgitation, cardiac function and mean pulmonary venous wedge pressure are closely correlated with mortality after bilateral pulmonary artery banding. Additional treatments, including operations, are considered to maintain cardiac function and not to raise pulmonary venous wedge pressure before the bidirectional Glenn procedure.

Case ReportsFatal air embolism during cardiopulmonary bypass: analysis of an incident and prevention measures.
Air embolism is a life-threatening complication during cardiopulmonary bypass. We present a case of a patient who suffered an air embolism during coronary bypass surgery, despite standard safety features and procedures. The patient died 3 days after surgery due to massive cerebral oedema. This case report gives a reconstruction of the event and the countermeasures undertaken to minimize the risk of recurrence.

Mid-term results of aortic root replacement using a self-assembled biological composite graft.
To report the mid-term results of aortic root replacement using a self-assembled biological composite graft, consisting of a vascular tube graft and a stented tissue valve. ⋯ Aortic root replacement using a self-assembled biological composite graft is an interesting option. Haemodynamic results are excellent, with freedom from structured valve failure. Need for reoperation is extremely low, but long-term results are necessary to prove the durability of this concept.
