Ideal and complicating factors for transcatheter tricuspid valve interventions28 63

ApproachIdeal factorsComplicating factors
Edge to edge repair

  • Coaptation defect<7 mm

  • Adequate leaflet mobility

  • Anteroseptal jet

  • Confined leaflet prolapse or flail leaflet

  • RV lead without primary leaflet obstruction

  • Gap>8.5 mm

  • Thick/short leaflets

  • Leaflet perforation

  • Difficult echocardiographic visualisation

  • CIED RV lead leaflet impingement

  • Anteroposterior jet location

  • Severe leaflet tethering

Annuloplasty

  • Annular dilation as principle mechanism of TR+central jet

  • No or mild tethering (tethering height<0.76 cm, tenting area<1.63 cm2, tenting volume<2.3 mL)

  • Adequate anatomic landing zone for anchor deployment

  • Severe annular dilatation exceeding device size

  • Severe tethering (tethering height >1.0 cm, tenting volume>3.5 mL)

  • Severe pulmonary hypertension

  • CIED induced tricuspid regurgitation+impingement

  • Anatomic proximity of RCA from annulus

  • CIED, cardiovascular implantable electronic device; RCA, right coronary artery; RV, right ventricle; TR, tricuspid regurgitation.
