DENVER—Coronary CT Angiography (CCTA) is not indicated for use in atrial fibrillation (AF) patents due to the problems it causes in terms of diagnostic accuracy, Thomas C. Gerber, MD, PhD, of the division of cardiovascular diseases at the Mayo Clinic, Jacksonville, Fla., said during a presentation Sept. 10 at the annual scientific sessions of the American Society of Nuclear Cardiology (ASNC). However, cardiac CT may be beneficial in some instances for this patient population when the right methods are used.

For patients with unfavorable coronary sinus (CS) vein anatomy, cardiac resynchronization therapy (CRT) via a surgical minithoracotomic approach is preferable to transvenous lead implantation, according to a study published in the July 26 issue of the Journal of the American College of Cardiology. However, an accompanying editorial recommended caution when deciding whether to recommend routine CT scans to define anatomy in possible CRT candidates due to iatrogenic radiation exposure.
