Anomalous origin of coronary artery from the opposite aortic sinus of Valsalva-a single center experience with a therapeutic conundrum.

Background: Coronary artery anomalies are rare congenital abnormalities, most often found incidentally on conventional coronary angiography and CT angiography (CTA). CTA better delineates the origin and course of anomalous coronaries. Anomalous origin of coronary artery from the opposite aortic sinus of Valsalva (ACAOS) has a prevalence of 1% with a very few having an interarterial (malignant) course.

Remote ischemic preconditioning for prevention of contrast-induced nephropathy - A randomized control trial.

Background: There is a lack of sufficient data regarding the protective effects of remote ischemic preconditioning (RIPC) in patients at risk of developing contrast-induced nephropathy (CIN). Thus, this study was conducted to determine whether RIPC as an adjunct to standard therapy prevents CIN in high-risk patients undergoing coronary intervention.

Methods: In a single-center, double-blinded, randomized controlled trial, 162 patients who were at risk of CIN received standard hydration combined with RIPC or hydration with sham preconditioning.

Radiofrequency ablation of incessant atrial tachycardia in an infant.

Ectopic automatic atrial tachycardia, an uncommon type of supraventricular tachycardia in children and adults, has been reported to be resistant to medical therapy unlike reentrant supraventricular tachycardia. We report a case of incessant atrial tachycardia in an infant, which was successfully treated with radiofrequency catheter ablation.
