- Abstract
- Background:Coronary sinus catheterization
is important in electrophysiological studies. However the morphologic
feature of the coronary sinus and its significance in patients with supraventricular tachycardia (SVT)
have not been determined. During diagnostic electrophysiological studies, coronary sinus catheterization was
easier in patients with atrioventricular nodal reentry tachycardia (AVNRT) than in patients with
atrioventricular reentry tachycardia (AVRT). Therefore, we studied coronary sinus morphology in patients
with SVT and compared AVNRT and AVRT patients. Methods:The size and shape of the coronary sinus
were measured in 13 patients who underwent retrograde coronary sinus venogram during electrophysiologic
study between May and June 1996. The diagnosis was 7 cases of AVNRT, 2 of Wolff-Parkinson-White
syndrome and 4 of concealed bypass tracts (mean age, 40 years:male vs female, 1:1.2). Results:The
mean coronary sinus ostial diameter was 10.4±2.0 mm;for AVNRT, it was 11.4±2.2 mm, and for AVRT it
was 9.3±1.0 mm in left anterior oblique projection (p=0.031). The mean coronary sinus-to-spine angle was
82.6±17.4°:AVNRT 95.4±24.4° and AVRT 67.7±15.2° in anterior posterior projection (p=0.035).
Conclusion:The coronary sinus ostial diameter of AVNRT patients was significantly larger than that of
AVRT patients. This finding may have important implications for arrythmia pathogenesis in such patients.
