Adenosine-induced torsade de pointes complicating a fractional flow reserve measurement in a right coronary artery intermediate stenosis

Cardiovasc Revasc Med. 2013 Mar-Apr;14(2):118-20. doi: 10.1016/j.carrev.2012.12.010. Epub 2013 Feb 19.

Abstract

We present the case of a 57 year-old patient that presented to our Institution with a positive treadmill stress test. Coronary angiography revealed an intermediate stenosis of the right coronary artery evaluated with a fractional flow reserve (FFR), complicated by torsade de pointes. Despite this being a very rare arrhythmic complication during FFR, its prompt recognition and treatment are of utmost importance.
