The patients were classified into three groups: Group I (34 patients) had a right ventricular (RV) to aortic systolic pressure ratio of &lt; 1, Group II (39 patients) had suprasystemic RV systolic pressures, and Group III (20 patients) included patients with elevated mean right atrial (RA) pressures irrespective of the RV systolic pressures. The percentage drop in immediate postdilatation peak systolic gradients (PSG) and the follow\u2010up PSG were similar in the three groups and were not influenced by any predilatation patient characteristics. A balloon\u2010annulus ratio &lt; 1 predicted a poorer follow\u2010up outcome. Nine patients, eight of Group III and one of Group II, experienced difficult procedures requiring sequential use of progressively larger balloon catheters. Eleven patients, six of Group II and five of Group III, experienced procedure\u2010related events (hypotension, bradycardia\/asystole, hypoxia, apnea, tachyarrhythmias, and seizures) and one patient (Group II) died. Although changes in immediate and follow\u2010up gradients after PBV are not influenced by the severity of PS, difficult procedures and procedure\u2010related events are particularly common in patients with severe PS and elevated RA pressures. A cautious and planned approach is therefore indicated in these patients.<\/jats:p>","DOI":"10.1002\/clc.4960160608","type":"journal-article","created":{"date-parts":[[2009,2,4]],"date-time":"2009-02-04T09:02:42Z","timestamp":1233738162000},"page":"497-502","source":"Crossref","is-referenced-by-count":11,"title":["Determinants of immediate and follow\u2010up results of pulmonary balloon valvuloplasty"],"prefix":"10.1002","volume":"16","author":[{"given":"S.","family":"Shrivastava","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Krishna Kumar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Dev","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Saxena","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gladwin","family":"Das","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,2,4]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02552069"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198208263070907"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(12)65015-0"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0033-0620(89)90013-3"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(88)90023-3"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(90)91387-L"},{"key":"e_1_2_1_8_2","doi-asserted-by":"crossref","first-page":"967","DOI":"10.1093\/oxfordjournals.eurheartj.a059421","article-title":"Balloon valvuloplasty of pulmonary stenosis in infants and children\u2014cooperative study of the German Society of Pediatric Cardiology","volume":"10","author":"Shmaltz AA","year":"1989","journal-title":"Eur Heart J"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.eurheartj.a059555"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810140203"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.83.6.1915"},{"key":"e_1_2_1_12_2","first-page":"107","article-title":"Nonsurgical treatment for pulmonic stenosis","volume":"23","author":"Shrivastava S","year":"1986","journal-title":"Ind Pediatrics"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5273(87)90081-7"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5273(87)90149-5"},{"key":"e_1_2_1_15_2","unstructured":"VasanRS ShrivastavaS DevV: Unusual electrocardiographic response during pulmonary balloon valvuloplasty.Int J Cardiol(in press)."}],"container-title":["Clinical Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fclc.4960160608","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/clc.4960160608","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T09:19:10Z","timestamp":1698225550000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/clc.4960160608"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,6]]},"references-count":14,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1993,6]]}},"alternative-id":["10.1002\/clc.4960160608"],"URL":"https:\/\/doi.org\/10.1002\/clc.4960160608","archive":["Portico"],"relation":{},"ISSN":["0160-9289","1932-8737"],"issn-type":[{"value":"0160-9289","type":"print"},{"value":"1932-8737","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,6]]}}}
