What does diminutive artery mean?
Angiographic evidence of diminutive coronary artery or arteries, defined as termination of the arterial tree less than or equal to two thirds the distance from coronary origin to the heart border and a vessel origin ≤2 mm diameter.
What is bridging in the heart?
Myocardial bridging occurs when the heart is malformed, with a bridge of muscle fibers overlying a section of a coronary artery, usually the left anterior descending (LAD) artery. When the heart beats, the artery is squeezed and normal blood flow is disrupted during both the pumping and relaxed cycles.

Is myocardial bridge life threatening?
Myocardial bridges have traditionally been considered a benign condition, but recent studies have demonstrated that the clinical complications can be dangerous; these complications include acute coronary syndromes, arrhythmias (including supraventricular tachycardia and ventricular tachycardia), exercise-induced …
Can you Stent a myocardial bridge?
Stent implantation in symptomatic patients with myocardial bridges can ameliorate peak intracoronary systolic pressure and vessel compression, normalize flow and abolish symptoms (42); however, concerns regarding perforation during stent deployment (21,43), stent fracture (44), in-stent restenosis (44-48) and stent …
