Left atrial enlargement (86.6%) and left ventricular hypertrophy (100%) were the most common findings. Bundle\u2010branch blocks (BBBs) were often demonstrated on preoperative studies, predominantly (46.7%) left BBBs. Left anterior fascicular blocks were seen in four patients (26.6%), one associated with right BBB. Electrocardiographic changes suggestive of myocardial infarction (MI) were seen in four patients preoperatively; postoperatively, all had extended to or within the lateral wall. Five additional patients developed lateral MIs postoperatively, for a total of 9 patients (60%) with postoperative signs of infarction (p &lt; 0.05). Electro\u2010 and vectorcardiography also showed significant postoperative lowering of QRS voltages (mean 40.74%) in all patients and a consequent difficulty to diagnose left ventricular hypertrophy, although the morphologic features did not change.<\/jats:p><jats:p><jats:italic>Conclusions<\/jats:italic>: These important ECG and VCG alterations are reflections of both the surgical technique and its clinical consequences.<\/jats:p>","DOI":"10.1002\/clc.4960260108","type":"journal-article","created":{"date-parts":[[2007,6,27]],"date-time":"2007-06-27T15:19:36Z","timestamp":1182957576000},"page":"36-42","source":"Crossref","is-referenced-by-count":1,"title":["Electrocardiographic and vectorcardiographic findings of patients undergoing reductive ventriculectomy (Batista operation)"],"prefix":"10.1002","volume":"26","author":[{"given":"Carlos Alberto","family":"Pastore","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nancy","family":"Tobias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Kaiser","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando F.","family":"Bacal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Luiz","family":"Aziz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis Felipe","family":"Moreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noedir","family":"Stolf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edimar","family":"Bocchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Franchini","family":"Ramires","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,12,5]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1590\/S0102-76381996000100002"},{"key":"e_1_2_1_3_2","first-page":"165","article-title":"Clinical outcome after left ventricular surgical remodeling in patients with idiopathic dilated cardiomyopathy referred to heart transplantation\u2014short term results","volume":"96","author":"Bocchi EA","year":"1997","journal-title":"Circulation"},{"key":"e_1_2_1_4_2","first-page":"395","article-title":"Partial ventriculectomy outcome upon mechanical properties, shape and geometry of the left ventricle in patients with dilated cardiomyopathies","volume":"67","author":"Bellotti G","year":"1996","journal-title":"Arq Bras Cardiologia"},{"key":"e_1_2_1_5_2","first-page":"1504","article-title":"Structural basis for heart failure: Ventricular remodeling and its pharmacological inhibition","volume":"91","author":"Chon JN","year":"1995","journal-title":"Circulation"},{"key":"e_1_2_1_6_2","first-page":"401","article-title":"Ventriculectomy\u2010a direct application of Laplace's law.
