Medically reviewed by Richard N. Fogoros, MD The right atrium is one of the heart's upper chambers that plays a role in blood ...

The patient was referred to a cardiac electro-physiologist for atrial flutter at age 56. Left-ventricular, right-ventricular and right-atrial size and systolic function were normal on ...

Left atrial pressure and central venous pressure (an estimate of right atrial pressure), measured through a catheter needle during surgery, were identified as the "gold standard." A novel combined ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve separates the right atrium and right ventricle. It opens due to a build-up of pressure in the right atrium ...

An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop. This results in a communication between the left and right atrium ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve is located between the right atrium and right ventricle and opens due to a build-up of pressure in the ...

Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich blood to all parts of the body. Do right and left seem backward? That's because you're looking ...

While it can be located in the right atrium or the ventricles, the most common location for a cardiac myxoma is the left atrium. The tumor can grow large enough to obstruct mitral valve inflow ...

The approach works by creating a connection between the left and right atrial chambers using a short pulse of energy to cut tissue, reducing pressure buildup within the left atrium. The pivotal ...
