Findings and procedure details
We retrospectively reviewed 148 coronary CTAs done in our institution during the last three years in order to study pulmonary veins’ and left atrium anatomy.
63 CTAs was performed in patients (65-80 years old) with atrial fibrillation who were admitted for electrophysiological procedures.
Coronary CTA was performed on a 64-slice source CT using ECG gating and bolus tracking.
Protocols of PVs and coronary arteries were used.
There was not thrombosis in the left atrium or left atrial appendage.
Variations and anomalies of PVs were examined.
The separate right middle pulmonary vein was the most usual supernumerary vein.
Surface-rendered images and a 3D model of the left atrium and the PV was created.
The distance of the esophagus from the PV ostium was measured.
Ostial diameters were measured by curved reformations.
