The relationship between pulmonary artery wedge pressure and left atrial pressure in man.

The pulmonary vein wedge pressure in man.

In 12 patients with atrial septal defect or anomalous pulmonary venous connection, pulmonary vein wedge mean pressure uniformly exceeded mean pressure in the left atrium or pulmonary vein and with one exception was less than mean pressure in the pulmonary artery. There was a positive correlation between pulmonary arteriolar resistance and the difference in pressure between pulmonary artery and ...

Relationship of pulmonary artery-wedge pressure to left atrial pressure in man.

The interrelations of the pulmonary arterial and venous wedge pressures.

APRESSURE recorded through a cardiac catheter wedged tightly in a small . pulmonary artery has been referred to as a "capillary," "venous" or "wedge" pressure. On the other hand, a pressure recorded through a cardiac catheter wedged into a pulmonary vein during thoracotomy and in intact animals has been referred to as a pulmonary venous wedge pressure'. Some investigators have found good correl...

اندازه گیری فشار شریان ریوی توسط داپلر و مقایسه آن با روش کاتتریسم

Pulmonary artery pressure can be estimated from right ventricular-right atrial pressure gradient in patients with tricuspid regurgitation. The most common approach is to estimate pulmonary artery systolic pressure from right ventricular pressure (assuming no pulmonic stenosis) determined as the sum of the right ventricular-right atrial pressure gradient and either an assumed or clinically deter...

The effect of the pericardium on ventricular systolic function in man.

To determine the role of the pericardium in man, ventricular function was studied in 20 patients who underwent pericardiotomy during coronary artery bypass surgery. Left and right ventricular function curves were generated before and after pericardiotomy by changing body position to alter venous pressure. Central venous (0--14 mm Hg) and pulmonary wedge pressures (1--25 mm Hg) ranged over norma...
