ARTICLE HIGHLIGHTS
Research background

Coronary sinus imaging is gaining importance due to improvement in electrophysiology techniques and wide spread use of left ventricular lead as a part of Cardiac resynchronization therapy.

Research motivation

Although standard technique is retrograde venogram, it has its own challenges.

Research objectives

To evaluate the feasibility of levophase of routine coronary angiography for studying coronary anatomy.

Research methods

We conducted a prospective observational in patients undergoing routine coronary angiography. In two angiographic views (left anterior oblique & right anterior oblique with cranial angulation), we evaluated the levophase for coronary sinus anatomy including ostial uptake, size, branches and angulation.

Research results

The levophase coronary angiography achieved good visibility in almost all patients. Most patients had a tubular coronary sinus ostia with size < 10 mm. Sharp take off between ostia and body as well tortuosity were seen only in a minority.

Research conclusions

Levophase coronary angiogram evaluation for coronary sinus anatomy is safe and highly effective.

Research perspectives

Large randomized studies are need to further substantiate the results.
