Patent foramen ovale and unexplained ischemic cerebrovascular events in children.
To consider the role of patent foramen ovale (PFO) in ischemic cerebrovascular event of unknown cause in children. ⋯ It appears that the role of PFO in ischemic cerebrovascular event of unknown cause in children may be underestimated. Contrast TCD with VM is a sensitive, noninvasive method for PFO detection, proved in our experience particularly suitable for children. In children with unexplained ischemic cerebrovascular event and presumed paradoxical embolism, percutaneous PFO closure should be considered.

Case ReportsParadoxical emboli through the patent foramen ovale as the suspected cause of myocardial and renal infarction in a 48-year-old woman.
We review the case of a 48-year-old woman who underwent elective percutaneous patent foramen ovale closure following successive renal and myocardial infarction with normal renal and coronary arteries, probably as a consequence of paradoxical emboli.

Comparative StudyDoes creatine kinase-MB (CK-MB) isoenzyme elevation following percutaneous coronary intervention with drug-eluting stents impact late clinical outcome?
The incidence of postprocedural creatine kinase (CK)-MB elevation to >3x the upper limit of normal after percutaneous coronary intervention (PCI) has been reported at rates of up to 18% in the bare metal stent era and is correlated with higher adverse cardiovascular outcomes. This study examined the incidence and prognostic significance of CK-MB elevations after drug-eluting stent (DES) implantation. ⋯ Postprocedural CK-MB > or =3x elevation following PCI with DES continues to be a marker for the complexity of coronary disease and lack of clinical success; and correlates with higher rates of subacute thrombosis as well as late adverse events at 6-months and 1-year postprocedure.

Stenting for superior vena cava obstruction in pediatric heart transplant recipients.
Superior vena cava (SVC) obstruction can be a complication in heart transplant recipients. We reviewed our experience with relief of SVC obstruction using endovascular stents in pediatric heart transplant recipients. ⋯ SVC obstruction can be an important complication following heart transplantation, especially in infants with previous cavopulmonary anastomosis, undergoing heart transplant using bicaval technique. SVC obstruction can be safely and effectively treated using endovascular stents.

The impact of advanced chronic kidney disease on in-hospital mortality following percutaneous coronary intervention for acute myocardial infarction.
The impact of advanced chronic kidney disease (CKD) on the outcomes of patients undergoing percutaneous coronary intervention (PCI) in the acute phase of myocardial infarction is poorly understood. We assessed the impact of CKD (stages 3-5) on the in-hospital outcomes of patients undergoing PCI for acute myocardial infarction (AMI) in a statewide registry. ⋯ Patients with AMI and advanced CKD who undergo PCI have more comorbidities and significantly worse in-hospital outcomes than patients without advanced CKD. Even after adjusting for these comorbidities, advanced CKD remains an independent predictor of increased in-hospital mortality.
