LBBB in aircrew with low cardiac risk: diagnostic application of multislice CT.

Introduction: Because of its excellent negative predictive value for diagnosing coronary stenoses, multislice computed tomography (MSCT) may be a way to assess the absence of significant coronary stenosis. We discussed its place in aeromedical decision-making for aircrew members with a low level of cardiovascular risk factors and acquired left bundle branch block (LBBB).

Methods And Results: During the period 2002-2004, 12 male aircrew members (mean age: 42.
