[Evaluation of coronary flow reserve using Doppler guide wire in patients with ampulla cardiomyopathy: three case reports].
Coronary flow velocity recordings were obtained in three patients with ampulla (Takotsubo) cardiomyopathy using Doppler guide wire. Immediately after admission, coronary angiography demonstrated no significant stenosis and normal coronary flow in the epicardial coronary artery. Left ventriculography showed abnormal wall motion of the left ventricle mimicking ampulla shape in all patients. The coronary flow velocity pattern was normal, but coronary flow reserve of the left anterior descending coronary artery was decreased by adenosine administration in all patients. The coronary flow reserve in the left circumflex and right coronary artery also decreased. Cardiac catheterization was performed during the follow-up period in two patients. Left ventriculography revealed almost normal wall motion of the left ventricle. The coronary flow reserve normalized in one patient.
