Subtotal occlusion of the right coronary artery by Cardioband and its successful intervention via retrograde approach. Interventional flashlight

Abstract

In recent years, transcatheter approaches have changed the therapy of valvular regurgitation. One of these new techniques is the Cardioband ® tricuspid valve reconstruction system (Edwards Lifesciences Corp., Irvine, CA, USA), which allows an adjustment of the ring size but may cause a temporary deformation or even occlusion of the right coronary artery (RCA) due to its close proximity. We report on a patient with symptomatic and subtotal occlusion of the RCA after Cardioband implantation. The distortion was so sharp-cornered that antegrade re-canalizations failed. Finally, the subtotal occlusion was re-opened via retrograde approach and this stent remained open in long-term follow-up. We think this complication should be known and considered when using the Cardioband system. Learning objectiveTranscatheter reconstruction of the tricuspid valve by Cardioband ® can lead to subtotal occlusion of the right coronary artery, which is difficult to re-canalize.
