Percutaneous dilation was performed on 63 patients with pulmonary stenosis (ages 3 months to 76 years, mean = 4.3 years). In 43 patients, a single balloon was used; in 20 patients two balloons were used simultaneously.<\/jats:p><jats:p>The pressure gradient across the pulmonary valve was determined with right ventricular and main pulmonary artery catheters. Pressure gradients simultaneously were estimated by continuous wave Doppler (CWD) during catheterization. The peak systolic ejection gradient was obtained by both techniques both pre\u2010 and postangioplasty. There was excellent linear correlation between the simultaneous catheter pressure gradient and the pressure gradient estimated by Doppler (r = 0.99). Follow\u2010up pressure gradient estimations by Doppler echocardiogram were obtained in 30 patients between 6 months and 30 months postcatheterization (mean = 13 months).<\/jats:p><jats:p>The mean preangioplasty gradient of 64 mm Hg (range 30\u2013160 mm Hg) was reduced to 22 mm Hg (range 2\u201331 mm Hg). A significant reduction of transvalvular gradient (52\u201395%, mean 68%) occurred in each patient. A linear correlation was found between the predilation gradient and the pressure gradient drop (r = 0.92). Mean follow\u2010up gradient by Doppler was 20 mm Hg (range 0\u201331 mm Hg), and there was no significant difference between these gradients and the postdilation gradient. No important complications were noted. These data confirm that balloon dilation angioplasty for valvular pulmonary stenosis is safe and effective, and suggest that stenosis does not recur.<\/jats:p>","DOI":"10.1002\/ccd.1810140203","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T13:01:05Z","timestamp":1172754065000},"page":"76-81","source":"Crossref","is-referenced-by-count":20,"title":["Balloon valvuloplasty for pulmonic valve stenosis\u2014two\u2010year follow\u2010up: Hemodynamic and doppler evaluation"],"prefix":"10.1002","volume":"14","author":[{"given":"Charles E.","family":"Mullins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Achi","family":"Ludomirsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin P.","family":"O'Laughlin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"III","given":"G.
