| Popis: | OMRAN, H., et al.: Echocardiographic Imaging of Coronary Sinus Diverticula and Middle Cardiac Veins in Patients with Preexcitation Syndrome: Impact on Radiofrequency Catheter Ablation of Posteroseptal Accessory Pathways. To determine the value of echocardiography for identifying coronary sinus (CS) diverticula and middle cardiac veins (MCVs) in patients with posteroseptal accessory pathways (PAPs), transthoracic (TTE) and transesophageal echocardiography (TEE) were performed in 18 consecutive patients with PAP and in 15 control subjects with left lateral accessory pathway before CS angiography. The size, shape, and location of CS diverticula and MCV were described and compared to angiography. TEE and angiography were concordant for the identification of diverticula (n = 5) and agreed for depicting MCV in 22 of the 27 cases. TTE revealed 4 of 5 diverticula and identified 4 of 27 MCV (P < 0.001). Fourteen MCV but no diverticula were found in the control subjects. There was no significant difference between transesophageal and angiographic measurements for the width (23.5 ± 4.9 vs 26.8 ± 6.6 mm) and height (13.5 ± 3.8 vs 15.7 ± 3.4 mm) of the diverticula, and the width (3.5 ± 0.7 vs 3.7 ± 0.6 mm) of MCV. TEE underestimated the length of the MCV (12.0 ± 1.8 vs 27.2 ± 6.0, P < 0.001). Delivery of radiofrequency energy within the neck of a diverticulum or within an MCV was successful in 5 of 5, and 6 of 13 cases in patients with PAPs, respectively. In conclusion, echocardiography was as reliable as angiography for detecting and describing CS diverticula and MCV in patients with preexcitation syndrome. Echocardiography is recommended prior to electrophysiological study because it may simplify radiofrequency catheter ablation. |
