Relationship between time of day, day of the week and in-hospital mortality in patients undergoing emergency percutaneous coronary intervention.
Previous studies have reported circadian variation in the rate of post-percutaneous coronary intervention (PCI) complications and mortality. ⋯ Our study shows a significant time-dependent effect on in-hospital deaths in patients treated with emergency PCI. Healthcare organization and circadian variation of ischaemic processes could explain this variation in mortality.

Multicenter StudyShould we close hypoxaemic patent foramen ovale and interatrial shunts on a systematic basis?
Rarely, hypoxaemia is associated with shunt reversal at the atrial level. Closure by interventional catheterization is the treatment of choice but indications and results have been studied insufficiently. ⋯ Hypoxaemic shunts are treated effectively by transcatheter closure, resulting in functional improvement in patients without respiratory insufficiency. When associated with chronic respiratory insufficiency, hypoxaemia often persists after shunt closure. In such cases, the right-to-left atrial shunt does not seem to be the main cause of hypoxaemia and the indication for closure is questionable.

Impact of purely internal thoracic artery T-graft technique on the mode and quality of surgical myocardial revascularization evaluated by early postoperative coronary angiography.
The use of the internal thoracic artery for coronary artery bypass has improved the results of such surgery. However, bypass using only the internal thoracic arteries sometimes requires a T-graft. This purely internal thoracic artery T-graft technique has progressively become part of our surgical protocol for coronary artery bypass surgery. ⋯ The exclusive recourse to the purely internal thoracic artery T-graft technique meant that it has been possible to dispense with other types of graft while achieving complete and effective revascularization of the coronary artery.
