Acute coronary no-flow phenomenon

The Acute Coronary no-flow phenomenon ( ger .: acute coronary no-flow, also: abrupt coronary no-flow; abbr .: ACNF) is a very rare phenomenon (<1%) of the lack of blood flow in one or up to all Coronary arteries as part of a transcoronary ablation of septal hypertrophy (TASH) . It is a life-threatening complication.

The cause is a spasm of the vascular muscles. The genesis is unclear, but an association with severe psychological stress in the patient prior to the procedure has been observed. The ACNF must be differentiated from a faulty injection of alcohol, which leads to an isolated flow interruption in the anterior interventricular branch (RIVA, LAD) or one of its side branches.

Therapeutically, high-dose Urapidil is given intracoronary, the resulting drop in blood pressure is compensated intravenously with norepinephrine .
