atrial flutter and (C) AF. Electrogram recordings in a patient with a focal pulmonary vein (PV) tachycardia originating from the right upper PV (RUPV). The fluoroscopic image (left anterior ...

This is called systemic circulation. Oxygenated blood is carried to the heart from the lungs in the pulmonary vein. It goes into the left atrium, through the bicuspid valve and into the left ...

the foci that initiate and possibly sustain the arrhythmia are generally located in the left atrium at the ostia of the pulmonary veins. 2 AF frequently becomes more persistent over time ...

As mitral stenosis progresses over time, the pressure in the left atrium rises. This pressure is transmitted to the pulmonary veins, the pulmonary vasculature, and eventually to the right side of ...

Catheter ablation for AF is a complex procedure, usually performed via femoral venous access, with a transseptal approach to the left atrium and the pulmonary veins. Higher success rates for AF ...

The ancient Greek philosopher and polymath Aristotle once concluded that the human heart is tri-chambered and that it was the ...

Pulmonary Vein Isolation Alone for Persistent AF ... followed by PVI and linear ablation targeting the left atrial roof, mitral isthmus, and cavotricuspid isthmus. The primary objective focused ...

The bicuspid valve is located between the left atrium and left ventricle and ... away from the right ventricle to the lungs. The pulmonary vein returns oxygenated blood from the lungs to the ...
