ABSTRACT

Objective:

To study the characteristics of coronary CT angiography (CTA) in patients with myocardial bridge (MB) with arrhythmia.

Methods:

Our study included 2 groups MB+arrhythmia group,n=31, clinical information as medical record, electrocardiogram (ECG), myocardial enzyme, echocardiography and coronary CTA findings were collected; MB group, n=30, the MB patients were without arrhythmia.

Results:

In MB+arrhythmia group, all patients were with mere MB, coronary artery disease, valve-structural heart diseases and other systemic diseases were excluded. There were 2/31 patients with ventricular fibrillation, 1 with atrial fibrillation, 5 with supraventricular tachycardia and 23 with ventricular tachycardia; 17/31 patients having deep type MB and 14 having superficial type MB. The myocardial systolic end diameter, diastolic end diameter by retrospective ECG gating and the stenosis at cross section of mural coronary MB by CTA were similar between 2 groups,P>0.05.

Conclusion:

MB+arrhythmia patients had no specific characteristics in coronary CTA; anatomical CTA feature may partly explain the myocardial ischemic symptom while couldn't clarify arrhythmia occurrence in relevant patients.
