Pulmonary Valve Replacement supported by syngo DynaCT Cardiac

Author: Prof. F. Berger, PD Dr. P. Ewert
German Heart Center Berlin, Germany

Patient History

13-year-old girl (40 kg) with pulmonary atresia, corrective surgery with xenograft 11 years ago. Now calcified stenotic and regurgitant pulmonary valve


Indication for transcatheter pulmonary valve replacement. 

Indication for syngo DynaCT Cardiac:
Clarifying spatial relationship of left coronary artery (LCA) and xenograft.


Double injection: RV + LCA, RV pacing 180 bpm.
Due to a very short distance between valve and LCA (approximately 1 mm) the decision was made for surgery instead of intervention.
