CORONARY SINUS DILATATION IN PATIENTS WITH THE ATRIAL FLUTTER

摘要

This study was undertaken to compare the size of the Coronary Sinus (CS) in patients performed catheter ablation for supraventricular tachycardia and atrial flutter. Thirty four consecutive patients (age; 49.0 +-19.4) with three different arrhythmias; i.e. atrial flutter (Afl; n = 12), atrioventricular nodal reentry '(AVNRT; n = 13) and accessory pathway (AP; n = 9) underwent retrograde coronary sinus venography for the cannulation of 2 Fr. micro-electrode catheter. In the RAO view of the CS venography, the size of the CS ostium was significantly larger in the patients with Afl compared to that with AVNRT or AP(Afl, 21.6 +- 3.5 mm ; AVNRT, 16.7 +- 3.0 mm ; AP, 16.4 +- 3.7 mm ; p<0.01). The size of posterior vein (PV) and marginal vein (MV) showed no significant difference between three groups. Patients with Afl had a larger size of CS compared to patients with AVNRT or AP, although there is no significant difference in the size of the PV or MV.
