Comparative StudyInadequate visualization and reporting of ventricular function from transthoracic echocardiography after cardiac surgery.
The purpose of this study was to determine the incidence of and risk factors for inadequate reporting of ventricular function from transthoracic echocardiography after cardiac surgery. ⋯ Transthoracic imaging is often inadequate in patients who have undergone recent cardiac surgery. Patient and surgical characteristics influence reporting of right and left ventricular function.

Comparative StudyLongitudinal assessment of neurocognitive function in rats after cardiopulmonary bypass: evidence for long-term deficits.
Neurologic and neurocognitive dysfunction after cardiopulmonary bypass (CPB) have been shown in both clinical and experimental settings. Although short-term outcome has been evaluated in rats, the assessment of neurocognitive dysfunction with long-term follow-up has not been reported in experimental CPB models. The objective of this study was to evaluate the effects of CPB on long-term neurocognitive function in the rat. ⋯ Compared with sham-operated controls, rats undergoing CPB showed worse neurologic and neurocognitive outcome early after surgery. Importantly, long-term deficits also persisted at 6 weeks after surgery.

Comparative StudyCardiac index validation using the pressure recording analytic method in unstable patients.
The authors investigated the accuracy and precision of the pressure recording analytic method (PRAM) in cardiac index measurement compared with thermodilution in unstable patients, a setting in which minimally invasive monitoring devices often fail. ⋯ This study showed that PRAM, a minimally invasive method for cardiac index assessment, is clinically useful even in unstable patients such as those receiving intra-aortic balloon pump and/or ongoing high doses of a inotropic drugs because of a low cardiac output syndrome but without atrial fibrillation.
