Evaluation of Cardiac Function Index as Measured by Transpulmonary Thermodilution as an Indicator of Left Ventricular Ejection Fraction in Cardiogenic Shock
INTRODUCTION The PiCCO transpulmonary thermodilution technique provides two indices of cardiac systolic function, the cardiac function index (CFI) and the global ejection fraction (GEF). Both appear to be correlated with left ventricular ejection fraction (LVEF) measured by echocardiography in patients with circulatory failure, especially in septic shock. The aim of the present study was to tes...
متن کاملRight ventricular function during positive end-expiratory pressure. Thermodilution evaluation and clinical application.
Right ventricular (RV) function was studied in 13 patients under controlled mechanical ventilation with positive end-expiratory pressure (PEEP) for adult respiratory distress syndrome. The assessment of RV function was made by the thermodilution technique. Calculations of RV ejection fraction (RVEF) and RV end-diastolic volume (RVEDV) were performed. In 11 patients, increasing PEEP was accompan...
متن کاملEffect of opening the pericardium on right ventricular hemodynamics during cardiac surgery.
The impact of the pericardium on right ventricular performance in the presence of normal filling pressures was evaluated using a rapid response RVEF thermodilution pulmonary artery catheter and TEE. In eight patients with normal right coronary arteries undergoing coronary artery bypass surgery, hemodynamic measurements revealed increased right ventricular end-diastolic and end-systolic volumes ...
متن کاملIntraoperative assessment of right ventricular volume and function.
OBJECTIVE Right ventricular function is an important aspect of global cardiac performance which affects patients' outcome after cardiac surgery. Due to its geometrical complexity, the assessment of right ventricular function is still a very difficult task. Aim of this study was to investigate the value of a new technique for intraoperative assessment of right ventricle based on transesophageal ...
متن کاملRole of pericardial constraint for right ventricular function in humans.
STUDY OBJECTIVE To analyze the extent of pericardial constraint on right ventricular function in humans. PATIENTS AND METHODS Twenty patients, 59 +/- 2 (mean +/- SEM) years old, undergoing coronary bypass surgery. Right ventricular volumes and pressures were evaluated using a rapid response Swan-Ganz thermodilution catheter. INTERVENTIONS Parameters were determined before and after pericard...
