Correlation of echocardiographic and hemodynamic parameters in XXXX assessment prior to heart transplantation.

@entity1 @entity120 @entity2786
INTRODUCTION: Invasive assessment of pulmonary artery pressure ( @entity2786 ), via right heart catheterization, is part of the usual protocol prior to heart transplantation. Echocardiography is considered a valuable technique to evaluate @entity2786 . We sought to determine the reliability of measurements of @entity2786 via a noninvasive technique, echocardiography, in relation to the estimated @entity2786 via right catheterization. We also determined its safety when invasive procedures are restricted to just @entity1 with @entity120 ( @entity120 ) according to echocardiographic parameters. MATERIALS AND METHODS: We performed a retrospective study of 67 right catheterizations performed in our hospital, within the heart transplant study protocol, from January 2000 to December 2006. @entity2786 parameters were estimated by echocardiography and right catheterization. RESULTS: Hemodynamically, 57.1% of the @entity1 had severe @entity120 (more than 45 mm Hg mean @entity2786 ); 13.2% moderate @entity120 (between 35 and 45 mm Hg mean @entity2786 ); 12.1% had mild @entity120 (between 25 and 35 mm Hg mean @entity2786 ); and 17.6% of @entity1 showed no @entity120 . Pearson correlation index with systolic @entity2786 (estimated via echocardiography) and mean @entity2786 (calculated via invasive method) was 0.69 (P < .001). @entity120 was considered significant when systolic @entity2786 estimated via echocardiography reached more than 40 mm Hg and mean @entity2786 estimated via right catheterization reached more than 35 mm Hg, the value from which the vasodilator test was carried out. According to these parameters, echocardiography showed a sensitivity of 89% to diagnose significant @entity120 and 46% specificity, with positive and negative predictive values of 70% and 76%, respectively.
