Randomized Controlled Trial Clinical Trial
Magnesium sulphate during transradial cardiac catheterization: a new use for an old drug?
To assess the effect of intra-arterial magnesium on the radial artery during transradial cardiac catheterization. ⋯ This study demonstrates that magnesium is a more effective vasodilator when compared to verapamil, with a reduced hemodynamic effect, and is equally effective at preventing radial artery spasm. As such, the use of this agent offers distinct advantages over verapamil during radial catheterization.

Review Case Reports
Spontaneous coronary artery dissection: case series and review.
Spontaneous coronary artery dissection (SCAD) is a rare but important cause of acute coronary syndromes. SCAD can cause unstable angina, acute myocardial infarction, and sudden death. Predisposing factors include atherosclerosis, the peripartum period, and structural and inflammatory conditions affecting the arterial wall. ⋯ Therapeutic options include medical therapy, percutaneous coronary intervention, and surgery. We present a series of patients with spontaneous coronary artery dissection at our institution. The etiology, pathogenesis, diagnosis, treatment, and prognosis of patients with coronary dissection are reviewed.

Case Reports
Use of intra-arterial papaverine for severe arterial spasm during radial cardiac catheterization.
Coronary angiography and intervention can be performed safely using the radial artery. However, arterial spasm is often encountered and usually amenable to nitrate/verapamil therapy. Rarely, surgical intervention is required to remove catheters and wires. Intra-arterial papavarine can be used to treat severe radial artery spasm and prevent the need for urgent surgical intervention.
