[Myocardial bridging and fractional flow reserve].

Rev Esp Cardiol. 2005;58(9):1117 1117 A 69-year-old patient with a history of hypertension was admitted to the hospital for an acute coronary syndrome. Coronary arteriography showed a myocardial bridge at the mid-distal third of the left anterior descending artery with marked systolic compression. The fractional flow reserve (FFR) following intravenous infusion of adenosine (140 μg/kg) was 0.68. Since an FFR value <0.75 had been documented, it was not necessary to repeat the measurement with dopamine inotropic stimulation, as has been recommended for functional assessment of myocardial bridges. The presence of a diastolic gradient in this patient suggests IM AG E S I N CA R D I O L O G Y
