Balloon occlusion angiography proved valuable in diagnosing coronary sinus ostial obstruction in three patients with single-ventricle physiology.
Case Report (n=3)
Preoperative diagnosis of coronary sinus ostial obstruction using balloon occlusion angiography is crucial in patients with single-ventricle physiology requiring a Glenn anastomosis to avoid inadvertent ligation.
Coronary sinus (CS) ostial obstruction decompressing through a left superior vena cava is a rare finding and presents unique risks to patients requiring a Glenn anastomosis for single-ventricle palliation. Preoperative diagnosis is imperative in order to avoid inadvertent ligation or coil occlusion. We report three cases with single-ventricle physiology and CS obstruction identified at cardiac catheterization. Balloon occlusion angiography proved valuable in making the diagnosis.

Janssen et al. (2004) conducted a case report in Single-ventricle physiology and coronary sinus obstruction (n=3). Balloon occlusion angiography was evaluated on Diagnosis of coronary sinus obstruction. Balloon occlusion angiography proved valuable in diagnosing coronary sinus ostial obstruction in three patients with single-ventricle physiology.
