Intraoperative flow profiles of arterial and venous bypass grafts to the left coronary territory.
The different mechanical and vasodilatory properties of arteries and veins may influence their flow profiles when used for coronary artery bypass grafting (CABG). This may be of significance when assessing the cut-off values for adequate flow. However, conduit-related flow differences are less examined. ⋯ No statistically significant difference was observed for MGF and pulsatility index between arterial and venous conduits. However, arterial grafts have significantly higher diastolic filling and backwards flow than venous grafts. Furthermore, arterial grafts have a significantly higher MGF in ONCABG versus OPCABG.

Multicenter Study Comparative Study Observational StudyBiological or mechanical prostheses for isolated aortic valve replacement in patients aged 50-65 years: the ANDALVALVE study.
The decision about whether to use a biological or a mechanical prosthesis for aortic valve replacement remains controversial in patients between 50 and 65 years of age and has yet to be addressed in a Mediterranean population. This research aimed to analyse long-term survival and major morbidity rates (30-day mortality, stroke, any prosthetic reoperation and major bleeding) within this population. ⋯ NCT03239509.

Multicenter StudyHiatal hernia after oesophagectomy: a large European survey.
Hiatal hernias (HH) after oesophagectomy are rare, and their surgical management is not well standardized. Our goal was to report on the management of HH after oesophagectomy in high-volume tertiary European French-speaking centres. ⋯ Surgical management of HH after oesophagectomy could be done by laparoscopy in patients with scheduled surgery but laparotomy or thoracotomy was preferred in urgent situations. The incidence of HH after oesophagectomy is higher and its onset earlier when laparoscopy is used at the initial oesophagectomy.

Locational impact of luminal communication on aortic diameter changes and reintervention in acute type I aortic dissection.
The aim of this study is to evaluate the locational impact of a luminal communication on aortic diameter changes and reintervention after surgical repair of acute type I aortic dissection. ⋯ A luminal communication at the proximal descending thoracic aorta (segment 1) is a significant factor for an increasing aortic diameter and reintervention after surgical repair of acute type I aortic dissection.

Observational StudyAcquired von Willebrand syndrome in paediatric patients during mechanical circulatory support.
Bleeding signs can become life-threatening complications in patients on mechanical circulatory support (MCS). Clinical phenotyping and comprehensive analyses of the cause of bleeding are, therefore, essential, especially when risk-stratifying patients during MCS workup. We conducted coagulation analyses and determined von Willebrand factor (VWF) parameters in a paediatric cohort on temporary extracorporeal life support, extracorporeal membrane oxygenation or long-term ventricular assist device support. ⋯ The AVWS prevalence in paediatric patients on MCS is 100% regardless of the types of devices tested in this study. The bleeding propensity of AVWS patients widely varies.
