Right atrial pressure-volume relationships in tricuspid regurgitation.
Pressure-volume relationships in the right atrium were examined before and after the creation of acute experimental tricuspid regurgitation in pigs. A 1.3 kHz multielectrode impedance catheter with a measuring current of 4 mA was used to determine instantaneous right atrial pressure and relative blood volume; right atrial dimension was assessed simultaneously with ultrasonic crystals attached t...

Pressure-volume relationships in right ventricle.
• Recently, we have reported on the pressure developed in the left ventricle when that chamber was made to contract under conditions closely approaching that of being isovolumic.' 2 More recently, the use of a latex balloon to change the amount of effort of the right ventricle yielded data on the pressure developed in the right ventricle at different volumes under nearly isovolumic conditions. ...
متن کاملRight atrial size and tricuspid regurgitation severity predict mortality or transplantation in primary pulmonary hypertension.
Primary pulmonary hypertension (PPH) is a fatal illness. In advanced stages only transplantation is able to increase survival. Echocardiography is useful for the assessment of these patients, but there is limited information about its prognostic value. With this goal, 25 consecutive patients, age: 36.7 +/- 12.7 years, were studied and followed up for a mean period of 29 months (range: 0.2-84). ...
