Myocardial bridging in a young patient with left ventricular hypertrophy: a combined approach with CT scan and color Doppler echocardiography.
In this report the authors deal with the combined approach of last generation computed tomography and color Doppler echocardiography to make a diagnosis of myocardial coronary bridging in a young patient with left ventricular hypertrophy. Double-source tomographic scan precisely identified the tunnelled segment of the left descending coronary artery (the first diagonal branch), whereas echocardiography allowed recognising diastolic and systolic velocity just in this vessel. Coronary velocity throughout the bridged artery was not particularly increased at rest and late after exercise, even if the patient had ST-T changes during cycling test. These findings likely support a benign pathophysiological significance of isolated bridging of secondary coronary branches.
