Echocardiography as a noninvasive Swan-Ganz catheter.

Doppler echocardiography in advanced systolic heart failure: a reliable noninvasive alternative to Swan-Ganz catheter

Background: Although several studies have demonstrated a good correlation between Doppler echocardiographic and invasive measurements of single hemodynamic variables, the accuracy of echocardiography in providing a comprehensive assessment in individual patients has not been validated. To assess the accuracy and clinical applicability of Doppler echocardiography in determining the entire hemody...

A Noninvasive Alternative to Swan-Ganz Catheter

Background—Although several studies have demonstrated a good correlation between Doppler echocardiographic and invasive measurements of single hemodynamic variables, the accuracy of echocardiography in providing a comprehensive assessment in individual patients has not been validated. The aim of this study was to assess the accuracy and clinical applicability of Doppler echocardiography in dete...

Cardiac output monitoring by echocardiography: should we pass on Swan-Ganz catheters?

Transesophageal echocardiography offers a noninvasive technique for the continuous monitoring of cardiac performance. The combination of 2-dimensional echocardiography and Doppler velocitometry provide assessment of cardiac anatomy, valve function and, ventricular loading conditions. Although transesophageal echocardiography has become accepted for perioperative monitoring, it is typically used...

Hemodynamic assessment in heart failure: role of physical examination and noninvasive methods.

Among the cardiovascular diseases, heart failure (HF) has a high rate of hospitalization, morbidity and mortality, consuming vast resources of the public health system in Brazil and other countries. The correct determination of the filling pressures of the left ventricle by noninvasive or invasive assessment is critical to the proper treatment of patients with decompensated chronic HF, consider...

Haemodynamic parameters obtained by transthoracic echocardiography and Swan-Ganz catheter: a comparative study in liver transplant patients.

OBJECTIVE To compare the haemodynamic measurements of cardiac output (CO), central venous pressure (CVP), pulmonary capillary wedge pressure (Pw) and pulmonary artery systolic pressure (PASP), obtained by Swan-Ganz catheter and transthoracic echocardiography. MATERIAL AND METHODS Prospective study in a Medical/Surgical Intensive Care Unit (ICU). A total of 41 post liver transplant patients we...

Vector flow imaging using ultrasound: intraoperative estimation of blood flow in the ascending aorta compared to transesophageal echocardiography and pulmonary artery catheter thermodilution
