Maximal blood flow acceleration analysis in the early diastolic phase for in situ internal thoracic artery bypass grafts: a new transit-time flow measurement predictor of graft failure following coronary artery bypass grafting.
Maximal graft flow acceleration (max df/dt) determined by transit-time flowmetry (TTFM) in the diastolic phase was assessed as a possible predictor of graft failure in coronary artery bypass patients. ⋯ The TTFM 5-polymial max df/dt value in the early diastolic phase may be a promising predictor of future graft failure.

Observational StudyTrainees can learn minimally invasive aortic valve replacement without compromising safety.
Minimally invasive aortic valve replacement (Mini-AVR) is a technically advanced procedure. However, it results in equivalent operative mortality, less bleeding and reduced intensive care/hospital stay when compared with conventional AVR. Our aim was to assess the impact of trainee performance on short-term outcomes of patients undergoing elective and urgent Mini-AVR where a significant proportion were performed by trainees. ⋯ Mini-AVR can be performed with a low conversion rate and hospital stay and taught to trainees without compromising safety.

Observational StudyA 25-year study of chordal replacement with expanded polytetrafluoroethylene in mitral valve repair†.
This study examines the outcome of mitral valve repair with chordal replacement using expanded polytetrafluoroethylene over the past 25 years. ⋯ Our 25-year follow-up demonstrated reliable long-term outcomes of chordal replacement with expanded polytetrafluoroethylene sutures.

Surgical modification for preventing a gothic arch after aortic arch repair without the use of foreign material.
Systemic hypertension is the main late complication after arch reconstruction in patients with arch obstruction. Gothic arch geometry is suspected to be one of its possible causes. Accordingly, we evaluated here if a modified arch repair technique using an autologous pulmonary patch is effective in preventing gothic arch development. ⋯ Our modified technique was proven to be not only highly effective in preventing gothic arch geometry, but also as equally safe in terms of early clinical outcomes as conventional arch reconstruction techniques.

Historical ArticlePectus excavatum in relief from Ancient Egypt (dating back to circa 2400 BC).
Pectus excavatum is one of the most common congenital deformities of the chest wall. The aim of the study was to analyse 621 artefacts (reliefs, sculptures, paintings) from Ancient Egypt in terms of anatomical defects of the chest. ⋯ The relief was from Niankhkhnum and Khnumhotep mastaba and dates back to circa 2400 BC. The authors think it is possible that the relief may represent a pectus excavatum deformity and believe the image will open up debate on the occurrence of this deformity in ancient times.
