Patients with Ebstein anomaly are known to have a higher incidence of interatrial communications and shunting of blood and its components through, mainly due to either streaming of tricuspid regurgitation or due to elevated right atrial pressure. Here we describe a case where permanent pacemaker lead kept a patent foramen ovale open leading to right-to-left shunting of blood and exertional hypoxemia. This is the first such case report in the published literature.

Background: Along with technological progress in coronary intervention, periprocedural complications and adverse outcomes have markedly improved, yet perioperative myocardial injury is a frequent complication during percutaneous coronary intervention (PCI) and is strongly associated with post-procedural cardiovascular morbidity and mortality. Epidemiological researchers have defined lipid and lipoproteins abnormality as a risk factor for atherosclerotic cardiovascular diseases. Although several studies focus on identification the correlation between the changes of lipid profile levels and ischemic markers, there is a little information about the role of lipid profile disturbance as a predictor of periprocedural myocardial injuries.

Regardless of the diabetic status of patients with coronary artery disease, hyperglycemia and hypoglycemia are adversely associated with cardiovascular events. The relationship between glucose levels and increased mortality risk in acute myocardial infarction has been shown through various glucose metrics; however, there is a dearth of multivariate analysis of the relationship between elective coronary angioplasty and preprocedural blood glucose levels. We evaluated the relationship between preprocedural blood glucose levels and myocardial injury in 1,012 consecutive patients who underwent elective percutaneous coronary angioplasty.

Background: Patients undergoing percutaneous coronary intervention are at serious risk of different complications such as periprocedural bleeding that can lead to myocardial injuries. Blood loss through puncture site hematoma formation and through catheter aspiration causes periprocedural hemoglobin drop.

Objectives: Although percutaneous coronary intervention is an effective treatment of coronary artery disease, it seems necessary to investigate the impact of complications on outcomes including myocardial infarction and possible mortality.

Background: Trauma still stands atop of the list of emergencies. Transfer of these patients via Emergency Medical Services (EMS) dispatch is critical with regard to importance of timing. This aspect has achieved greater importance due to population increase and telephone triage.

Background: Cardiac resynchronization therapy (CRT) has been accepted as an established therapy for advanced systolic heart failure. Electrical and mechanical dyssynchrony are usually evaluated to increase the percentage of CRT responders. We postulated that QRS notch can increase mechanical LV dyssynchrony independently of other known predictors such as left ventricular ejection fraction and QRS duration.
