Equilibrium Radionuclide Angiocardiography

To study the effect of septic pulmonary hypertension on right/left ventricular intrapericardial interactions thirteen trauma patients, seven septic and six non-septic controls, were compared. Ventricular volumes were derived from firstpass or gated equilibrium radionuclide angiocardiography, and related to body surface area. Systemic and pulmonary pressures were measured invasively. Pulmonary arterial pressure was significantly increased in the sepsis group. Although right ventricular end-diastolic volumes were higher in sepsis, left ventricular end-diastolic volumes were not decreased. In terms of intrapericardial right/left ventricular interactions these results indicate that the right and left ventricles operate independently in septic pulmonary hypertension.

SummaryEquilibrium radionuclide angiocardiography (ERNA) was performed at rest in 30 patients with chronic respiratory failure (CRF) in order to evaluate right ventricular performance and wall motion. The usual indices of left ventricular performance were also recorded and correlated with right ventricular parameters. Only CRF patients without clinical, electrocardiographic or echocardiographic criteria suggestive of congenital, valvular, hypertensive or ischemic heart disease were studied. A RV dyskinesis was detected in 5 of the 30 patients, occurring however only in stage II—III CRF, as if a longstanding RV pressure overload were necessary for a RV dyskinesis to develop. No significant differences were found between patients with and without RV dyskinesis for all the functional ERNA parameters (i.e. LVEF, RVEF, PER, PFR) On the other hand, a significant correlation between the stage of the CRF and RVEF was observed.
