The double helix angiography of right coronary arteries: false lumen stenting of a type F right coronary artery spiral dissection with late recanalization of the true lumen and occlusion of the stented false lumen
Abstract
Overview
Guide catheter induced dissection of coronary arteries is an uncommon, but serious complication of coronary
angioplasty. Treatment can include emergent coronary artery bypass grafting to the affected vessel or percutaneous
intervention including wiring the true lumen and exclusion stenting of the dissection flap to prevent further
propagation. Detailed descriptions have been published of techniques of intentional passage of guide wires into
the false lumen and reentry into the true lumen with chronic total occlusions. We present an unusual case of
what appeared to be successful intentional false lumen stenting with reentry into the true lumen of an iatrogenic
dissection of the right coronary artery with restoration of TIMI III coronary flow which, one year later, was complicated
by recanalization of the true lumen and occlusion of the stented false lumen causing symptomatic angina.
