Background

Real-time 3-dimensional echocardiography (RT3DE) to visualize the coronary sinus (CS) was compared with multislice cardiac tomography (MSCT).

Methods

In all, 37 consecutive patients undergoing MSCT received RT3DE a few hours later. Group A (n = 22) had normal left ventricular dimension/function, whereas group B (n = 15) had heart failure.

Results

The CS could be visualized in both groups (91 % and 93 % ) with a significantly larger diameter in B. Systolic CS diameter was always larger than diastolic, but patients with heart failure showed significantly less difference (7.6 % ¡À 4.2 % vs 12.2 % ¡À 6.1 % , P < .05). When systolic and diastolic measurements were possible, MSCT and RT3DE agreed (Lin R = ?.09 [95 % confidence interval 0.73-0.93]) but less so from the proximal to mid/distal segments (Lin R 0.90, 0.61, 0.41, respectively). Observers learned the procedure in approximately 5 minutes.

Conclusion

The CS can be visualized and quantitatively assessed by RT3DE in an easily learned procedure that agrees with MSCT results, especially in patients with heart failure.
