Pulmonic Stenosis Stenosis Rheumatic inflammation Supravalvular obstruction Treatment if P-P >50mmHg Size the balloon at 1.25 to annulus Regurgitation Treatment of Tetralogy Congential malformation of valve Associated with VSD, carcinoid, rheumatic involvement, trauma

9 Investigational Device only in the US; Not available for sale in the US Perspective >250,000 cases of significant Mitral Regurgitation diagnosed annually in the US Current therapeutic options: –Medical management Effective in symptom management Ineffective in treating underlying pathophysiology or disease progression –Surgical Repair or Replacement (Standard of Care) Effective yet invasive with associated morbidity Only ~20% of patients with significant MR undergo MV surgery Unmet need for an effective less invasive option

Conclusions The treatment of pulmonic stenosis involves valvuloplasty with good long term results Emerging technologies allow treatment of valvular disease previously thought to be only operable
