Origin of all three major coronary arteries from the right sinus of Valsalva: clinical, angiographic, and magnetic resonance imaging findings and incidence in a select referral population.

Objective: We sought to determine the incidence and imaging features by coronary angiography and cardiac magnetic resonance imaging (MRI) of anomalies in which the right, circumflex, and left anterior descending coronary arteries arise separately from the right sinus of Valsalva.

Background: The anomalous origin of all major coronary arteries from separate ostia in the right sinus of Valsalva has been reported as exceedingly rare, with mainly isolated cases reported. A knowledge of the origin and proximal courses of aberrant arteries is critical for patient management.

Live three-dimensional transthoracic echocardiographic delineation of patent ductus arteriosus.

We report an adult patient with a patent ductus arteriosus in whom live three-dimensional transthoracic echocardiography provided comprehensive assessment of the morphology and pathophysiology of the lesion.

Transesophageal Echocardiographic Diagnosis of Right-Sided Aortic Arch.

We present the transesophageal echocardiographic findings in two adult patients with right-sided aortic arch: one without dissection and the other with traumatic aortic injury (dissection). In both patients, the branching pattern was the left common carotid artery and then the right common carotid artery, followed by the right and left subclavian arteries. The technique for the diagnosis of this anomaly and the identification of adjacent vascular structures using contrast echocardiography is described.
