MiCardia enCorSQ device enables late-stage adjustable annuloplasty for ischemic MR via temperature-induced diameter reduction.
Describes the surgical technique for implanting and activating the adjustable MiCardia enCorSQ annuloplasty device for ischemic mitral insufficiency.
May enable late adjustable annuloplasty in ischemic MR; leaves open durability and outcomes in prospective trials.
Presentation of the MiCardia enCorSQ annuloplasty device implantation technique for ischaemic mitral regurgitation including late-stage activation: exposure of mitral valve using video-assisted right lateral mini-thoracotomy, annuloplasty, tunnelling of permanently attached lead through the left atrial wall and subcutaneous implantation; and late activation: minor cut-down procedure for lead exposure, connection to proprietary energy source (MC-100 RF generator), echocardiography and fluoroscopy guidance, anterior-posterior diameter reduction of memory-shape alloy core annuloplasty device by raising the temperature a few degrees above body temperature.

Czesla et al. (2013) studied Ischaemic mitral insufficiency. MiCardia enCorSQ annuloplasty device was evaluated. The MiCardia enCorSQ annuloplasty device implantation technique enables late-stage adjustable mitral annuloplasty for ischaemic mitral regurgitation via temperature-induced diameter reduction.
