We proposed a simple echocardiographic method to assess the RV dimensions and evaluated the relationship between linear echocardiographic measures of the RV and RV volumes obtained by cardiovascular magnetic resonance imaging (CMR). Methods: A total of 45 patients (27.4 \u00b1 11.2 years; 40% male) with repaired TOF underwent CMR and echocardiography. Using echocardiography, RV dimensions were assessed from the parasternal short\u2010axis view using the longest RV internal diameter perpendicular to the mid\u2010interventricular septum. Significant RV dilatation was defined as an RV end\u2010diastolic volume index &gt;160 mL\/m<jats:sup>2<\/jats:sup> on CMR. Results: There were significant correlations between RV dimensions determined by echocardiography and the pulmonary regurgitation fraction, RV size, and function determined by CMR. The cutoff values of echocardiographic RV outflow tract (RVOT), end\u2010systolic and end\u2010diastolic dimension indices, and the combination of RVOT and end\u2010diastolic dimension indices to determine significant RV dilatation were 19.0, 19.4, 24.5, and 45.2 mm\/m<jats:sup>2<\/jats:sup>, respectively. The positive and negative predictive values for significant RV dilatation were 89.7% and 68.8% with RVOT diameter index \u226519.0 mm\/m<jats:sup>2<\/jats:sup>, 85.0% and 52.4% with RV end\u2010systolic dimension index \u226519.4 mm\/m<jats:sup>2<\/jats:sup>, 87.5% and 64.7% with RV end\u2010diastolic dimension index \u226524.5 mm\/m<jats:sup>2<\/jats:sup>, and 92.3% and 80.0% with the combination of RVOT and end\u2010diastolic dimension indices \u226545.2 mm\/m<jats:sup>2<\/jats:sup>, respectively. Conclusion: Echocardiography can be used to assess RV size in patients with repaired TOF with acceptable correlations with CMR as the reference standard.<\/jats:p>","DOI":"10.1111\/j.1540-8175.2012.01766.x","type":"journal-article","created":{"date-parts":[[2012,7,2]],"date-time":"2012-07-02T16:21:16Z","timestamp":1341246076000},"page":"1239-1246","source":"Crossref","is-referenced-by-count":13,"title":["Echocardiography
