Transcatheter aortic valve implantation for tricuspid aortic valve with a calcium bridge between the cusps: a case report.

To our knowledge, this is the first report of TAVI for a tricuspid AV with a 'calcium bridge' between the non-coronary and left cusps. In our patient, the unique structure of cusp fusing in the centre seemed to be caused by an acquired atherosclerotic process, as documented using a contemporary technique, i.e. MDCT. Cracking the calcium bridge with a balloon aortic valvuloplasty ensured that the THV adequately expanded. Severe AS caused by a calcium bridge may be treated with detailed evaluation of the AV morphology together with a procedural strategy planning.
