OBJECTIVES: Since 2004, different techniques for the Potts shunt have been used in patients with incurable pulmonary arterial hypertension. However, the experience with these interventions in a single institution is limited. We present our series of Potts shunts in children with pulmonary arterial hypertension. METHODS: Eight patients with suprasystemic pulmonary arterial hypertension (pulmonary artery-to-aorta mean pressure ratio of 1.39 ± 0.30) had a Potts shunt at the median age of 13...

OBJECTIVES: Recent studies have shown that patients with syndromic thoracic aortic aneurysm, particularly patients with bicuspid aortic valve, have increased blood levels of transforming growth factor β1 (TGF-β1), indicating this molecule as a prognostic biomarker. However, it is not known whether TGF-β1 is also elevated in the blood of patients with tricuspid aortic valve and aortic dilatation. METHODS: We analysed the plasma levels of TGF-β1 in 52 patients with tricuspid or bicuspid aortic valve and with normal or dilated ascending aorta who underwent cardiac surgery in our hospital...

Subvalvular techniques are gaining ground as adjunct procedures for addressing ischaemic mitral regurgitation. The aim of this study was to describe the different techniques and assess their results. A systematic review of the literature was performed. The end points of interest were recurrence of mitral regurgitation, cardiac events and early and late echocardiographic measurements. After initial screening, 450 articles were identified, of which 24 provided the best available evidence on the topic. The different subvalvular techniques had similar mortality rates when compared with the standard restrictive annuloplasty...

OBJECTIVES: : Small aortic annuli are challenging in aortic valve replacement. Prosthesis-patient mismatch, accompanied by high transvalvular gradients and small orifice area, is an often faced problem impairing postoperative outcome. The new TRIBIO bioprosthesis aims to enable enhanced haemodynamics, being increasingly important with decreasing annular size. This study compares ex vivo hydrodynamics of TRIBIO with 2 established bioprostheses in small annuli at different stroke volumes, simulating 'rest' and 'exercise', and evaluates haemodynamics of TRIBIO in a sheep model...

A 52-year-old man sustained a sternal fracture after a blunt traumatic chest injury. He was in severe pain in the intensive care unit, which resulted in difficulty breathing and increased analgesic requirement, and a decision was made to stabilize his manubrial fracture. Orthopaedic and thoracic surgeons jointly performed open reduction and internal fixation of the displaced manubrial fracture using 2 distal clavicle locking plates. This resulted in improvement in patient's pain and helped with his subsequent recovery and discharge from the hospital...

OBJECTIVES: Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. METHODS: A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013...

OBJECTIVES: Aortopexy is widely used; however, many surgeons still regard it with suspicion. To date, there are only a few large series and minimal long-term data. Against this background, our goal was to report our experience, particularly with regard to the recent expansion of indications and modification of diagnostic routine and surgical strategy. METHODS: Between 1994 and 2012, 53 patients (mean age: 1.1 years; 5 weeks-10.2 years) were operated on. Tracheomalacia after the operation for oesophageal atresia was the main indication for aortopexy (74%), followed by tracheal compression by the innominate artery (17%) and other selected indications (9%)...
