Multicenter StudyIs a predominant left-to-right shunt associated with migraine?: A prospective atrial septal defect closure study.
A right-to-left shunt, as seen in patients with a patent foramen ovale, seems to be associated with migraine. An atrial septal defect (ASD), however, is characterized by a predominant left-to-right shunt (LRS). We prospectively evaluated the effect of percutaneous ASD closure on migraine ⋯ We found a high prevalence of migraine in patients with an ASD, and observed prospectively a reduction in the occurrence of migraine, especially migraine with aura, 1 year after percutaneous closure.

Case ReportsCombined use of Impella device and intra-aortic balloon pump to improve survival in a patient in profound cardiogenic shock post cardiac arrest.
Patients who suffer cardiogenic shock after cardiac arrest have a very poor prognosis. Left ventricular assist devices have proven to be useful in these patients to improve survival. ⋯ We describe a case where intra-aortic balloon pump by itself was not enough to provide hemodynamic support in a patient with cardiogenic shock after cardiac arrest. The Impella Recover LP 2.5 system (ABIOMED, Inc., Danvers, MA) was successfully used along with the balloon pump for hemodynamic support and resulted in dramatic improvement of the patient's condition.

Comparative StudyImpact of day versus night as intervention time on the outcomes of primary angioplasty for acute myocardial infarction.
Conflicting datas exist regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) when the intervention is performed during night hours. ⋯ Primary PCI can be performed safely during the night at a high-volume PCI center with suitable and effective organization of cardiology department and catheterisation laboratory with 24 hours per day, 7 days per week onsite staffing.

Case ReportsThe risk of cardiac complications following noncardiac surgery in patients with drug eluting stents implanted at least six months before surgery.
Given the anecdotal reports and case series suggesting that drug-eluting coronary stents [DES] may be still vulnerable to coronary thrombosis after six months, we sought to assess this risk in patients undergoing non-cardiac surgery six months after stenting. ⋯ Perioperative cardiac events during non cardiac surgery after six months of DES deployment still occur. These cardiac complications [not entirely prevented by continued dual antiplatelet agents] remain a matter of diagnostic and therapeutic challenge and concern.

The impact of micro troponin leak on long-term outcomes following elective percutaneous coronary intervention.
To evaluate the clinical impact of microleaks of troponin, which are below the reference standard defining troponin elevation, on cardiovascular outcomes in stable coronary patients undergoing elective percutaneous coronary intervention (PCI). ⋯ Microleak of troponin following elective PCI suggests myocardial injury and predicts an increased risk of subsequent MI and death. Troponins should be routinely assessed following PCI, and preventive therapies are needed to reduce micro and macro troponin elevation in the PCI setting.
