The apparent benefits at 2 years observed in the nonrandomized ALT-FLOW study pave the way for a sham-controlled trial.

Left atrial enlargement refers to dilation of the left atrium which occurs from multiple disease states that can chronically increase the left atrial pressure. These include congestive heart ...

A novel transcatheter-implanted system that shunts blood flow from the left to right atrium through the coronary sinus has ...

The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium. Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich ...

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the ...

When left atrial enlargement occurs, it takes longer for cardiac action potentials to travel through the atrial myocardium; thus, the P wave also lengthens. Therefore, the criteria for diagnosing ...

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 ...
