ABSTRACT
The Cardioband system is a transcatheter direct annuloplasty device that is implanted in patients with severe symptomatic functional mitral regurgitation (MR) due to annulus dilatation and high surgical risk. This device covers the posterior two-thirds of the annulus, from the anterolateral to the posteromedial commissure, implanted in close proximity of the left circumflex artery, atrioventricular (AV) conduction system, and coronary sinus. We present the case of an 80-year-old-gentleman with prohibitive surgical risk, treated with Cardioband implantation for functional MR with an evident P1-P2 cleft and P2-P3 indentation, a relative contraindication to MitraClip implantation. We achieved procedural success with significative mitral annulus reduction (30% anteroposterior reduction from 37 to 26 mm) and MR reduction (from grade 4 to grade 1-2). A late onset Mobitz 2 AV block developed after 26 hr and evolved to complete AV block in the following day, requiring definitive biventricular pacemaker (PM). Less than 200 Cardioband implantations have been performed but, to our knowledge, this is the first reported AV block, possibly facilitated by the pre-existing bifascicular block, suggesting the opportunity of prolonged ECG monitoring after Cardioband like any other mechanical transcatheter structural intervention possibly affecting the AV conduction system.
