Percentage of peak-to-peak pulsatility of portal blood flow can predict right-sided congestive heart failure

AIM: To study the change of portal blood flow for the prediction of the status of right-sided heart failure by using non-invasive way.METHODS: We studied 20 patients with rheumatic and atherosderotic heart diseases. All the paUents had constant systemic blood pressure and body weight 1 week prior to the study. Cardiac index (CI), left ventricular end-diastolic pressure (LVEDP), mean aortic pressure (AOP), pulmonary wedge pressure (PWP), mean pulmonary arterial pressure (PAP), mean right atrial pressure (RAP), right ventricular end-diastolic pressure (RVEDP) were recorded during cardiac catheterization. Ten patients with RAP
