deoxygenated blood from the superior and inferior vena cava and the coronary sinus collect in the right atrium. From there, blood flows across the tricuspid valve into the right ventricle, where it is ...

The two ventricles (right ... and the left atrium is filling with oxygenated blood from the lungs. The tricuspid and mitral valves are closed during systole, and the pulmonic and aortic valves are ...

Small branches to the right atrium, ventricle, and conus or sinus node, are frequently observed. The RCA shows more displacement during the cardiac cycle than does the left coronary artery.

intraperitoneal injection), and right ventricular systolic pressure (RVSP) was recorded by PowerLab system (AD Instruments) using a Millar catheter (Millar Instruments, US) inserted into the right ...

Left ventricular stiffness and contractility, characterized by the end-diastolic pressure-volume relationship (EDPVR) and the end-systolic pressure-volume relationship (ESPVR), are two important ...

If the reduction in MR was inadequate with one clip, the same clip was repositioned or a second clip was placed. Invasive LA pressure was recorded prior to withdrawal of the sheath from the LA to the ...

Right ventricle (RV) volume overload relating to left-to-right shunting in patients with large atrial septal defects (ASDs) or pulmonic regurgitation after repair of tetralogy of Fallot (TOF) or ...

This makes it harder for blood to flow from your heart through your lungs because of the pressure inside these vessels. As a result, the lower chamber of your heart, called the right ventricle ...
