Randomized Controlled Trial Multicenter Study Comparative StudyCoronary CT angiography versus myocardial perfusion imaging for near-term quality of life, cost and radiation exposure: a prospective multicenter randomized pilot trial.
Clinical outcomes and resource utilization after coronary computed tomography angiography (CTA) versus myocardial perfusion single-photon emission CT (MPS) in patients with stable angina and suspected coronary artery disease (CAD) has not been examined. ⋯ In a pilot randomized controlled trial, patients with stable CAD undergoing coronary CTA and MPS experience comparable improvements in near-term angina-related quality of life. Compared with MPS, coronary CTA evaluation is associated with more aggressive medical therapy, increased coronary revascularization, lower total costs, and lower effective radiation dose.

Case ReportsMitral annuloplasty ring dehiscence demonstrated by preablation cardiac computed tomographic angiography: influence on radiofrequency ablation of atrial fibrillation.
We present a case that demonstrates mitral valve annuloplasty ring dehiscence discovered on a cardiac computed tomography imaging study performed prior to radiofrequency ablation for atrial fibrillation. We describe the relevant imaging findings and the clinical implications this finding has on catheter selection and patient safety during a radiofrequency ablation procedure.
