..............................................................................................................................................The Role of Tissue Doppler Imaging in Predicting Left Ventricular Filling Pressures in Patients Undergoing Cardiac Surgery: An Intraoperative Study
................................................................................................................................... Conclusion: Intraoperative TEE was unable to accurately predict LVFP in patients undergoing cardiac surgery. PAC may continue to be the gold standard in the assessment of LVFP for this patient population...................................................................................................................................At both pre- and post-CPB, there was no significant correlation between lateral, septal, and mean E/E′ obtained by TEE and PCWP......................................................................................................................................
A informação acima é muito contundente. Por que parâmetros supostamente confiáveis de estimar as pressões capilares falharam em teste ideal de correlação? Até ler esse artigo acreditava em uma correlação alta!
