Abstract

Because of the variety of their anatomy and clinical implications, coronary anomalies tend to confuse many observers. Recently, our group and other investigators have proposed that only 1 specific type of anomaly, by means of a specific mechanism, is able to cause both symptoms of myocardial ischemia and sudden death. This anomaly is known as anomalous origin of a coronary artery from the opposite sinus of Valsalva, with intramural course (ACAOS). Its defining pathophysiologic feature is that the proximal section of the ectopic artery has an intramural course, which leads to variable degrees of functional obstruction. Herein, we describe an unusual, previously unreported coronary anomaly: a "normal origin" of the left main coronary artery from the left sinus of Valsalva that resulted in progressive, critical ischemia. The proximal few millimeters of this artery were intramural, embedded into the aortic-sinus wall, and laterally compressed. Therefore, this anomaly may be regarded also as "ACAOS of the left coronary artery without an ectopic origin." Angiography and intravascular ultrasonography revealed a variable degree of obstruction without intimal thickening and, likely, without spasm. Surgical repair, including ostioplasty, completely relieved the patient's clinical symptoms.

Abstract

Myocardial bridge (MB) or tunneled coronary artery is an inborn abnormality, which implicates a systolic vessel compression with a persistent mid-late diastolic diameter reduction. Myocardial bridges are often observed during coronary angiography with an incidence of 0.5%-5.5%. The most involved coronary artery is the left anterior descending artery followed by the diagonal branches, the right coronary artery, and the left circumflex. The overall long-term prognosis is generally benign. However, several risk or precipitating factors (e.g., high heart rate, left ventricular hypertrophy, decreased peripheral vascular resistance) may trigger symptoms (most frequently angina). Herein, we describe two cases of symptomatic myocardial bridge, where medical treatment (i.e., inotropic negative drug) and coronary stenting were successfully utilized to treat this pathology. We also focus on the clinical presentation, and the diagnostic and therapeutic modalities to correctly manage this frequently observed congenital coronary abnormality, underlining the fact that in cases of typical angina symptoms without any significant coronary artery disease, MB should be considered as a possible differential diagnosis.
