Comparative Study Observational StudyTrends in treatment delays for patients with acute ST-elevation myocardial infarction treated with primary percutaneous coronary intervention.
Treatment delay is an important prognostic factor for patients with acute ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). We aimed to determine recent trends in these delays and factors associated with longer delays. ⋯ Though the delays inside the hospital have increased they are still mostly within the ESC guidelines. Still, only about half of the patients are treated within a system delay of recommended two hours. Albeit our results are good in comparison with previous studies, further efforts for decreasing the delays particularly within the EMS should be established.

Routine angiography in survivors of out of hospital cardiac arrest with return of spontaneous circulation: a single site registry.
Coronary revascularization in resuscitated out of hospital cardiac arrest (OOHCA) patients has been associated with improved survival. ⋯ Acute myocardial infarction was the commonest cause of OOHCA and a high rate of survival to discharge was seen with a strategy of routine angiography and revascularization.

Preoperative risk factor analysis of postoperative stroke after Cox-maze procedure with mitral valve repair.
Atrial fibrillation (AF) is a life-threatening arrhythmia that carries the high risk of thromboembolic complication. Stroke often develops in patients who undergo successful Cox Maze procedure, despite the fact that the procedure has shown a high rate of success in sinus conversion from AF. This study examined the preoperative risk factors predictive of stroke following Cox Maze procedure in patients with mitral valve disease. ⋯ In the group of patients who underwent the Cox-Maze procedure with mitral valve repair, having a stroke history was the only preoperative risk factor that could lead to a stroke event after surgery. Accordingly, patients with affliction of ischemic stroke, albeit sustained sinus rhythm, may require prophylactic anticoagulation.

Repeated epinephrine doses during prolonged cardiopulmonary resuscitation have limited effects on myocardial blood flow: a randomized porcine study.
In current guidelines, prolonged cardiopulmonary resuscitation (CPR) mandates administration of repeated intravenous epinephrine (EPI) doses. This porcine study simulating a prolonged CPR-situation in the coronary catheterisation laboratory, explores the effect of EPI-administrations on coronary perfusion pressure (CPP), continuous coronary artery flow average peak velocity (APV) and amplitude spectrum area (AMSA). ⋯ In an experimental CA-CPR pig model repeated doses of intravenous EPI results in a significant increase in APV only after the first injection despite increments in CPP also during the following 2 injections indicating inappropriate changes in coronary vascular resistance during subsequent EPI administration.

Case ReportsPartial anomalous pulmonary venous connection to superior vena cava that overrides across the intact atrial septum and has bi-atrial connection in a 75-year-old female presenting with pulmonary hypertension.
Partial anomalous venous connection (PAPVC) is a rare congenital heart disease where the blood flow from one or more pulmonary veins (but not all) returns to the right atrium or systemic venous circulation and is often associated with a sinus venosus atrial defect (SVD). Transthoracic echocardiography (TTE) can provide limited information for this anomaly and the diagnosis of this congenital defect has been a clinical challenge. ⋯ This case indicates the need to exclude a PAPVC and SVD in unexplained pulmonary hypertension, and MCTA is a reliable non-invasive imaging technique with high resolution and wide anatomic coverage. The case also demonstrates that the coexisting SVD with PAPVC is an anomalous venous connection instead of atrial septal defect (ASD) and its key feature is the overriding of SVC or IVC across the intact atrial septum.
