Recent studies have provided important information on the nature of PV electrophysiology and of the role of the PVs in initiation and maintenance of AF. Reentry is responsible for the majority of ...

The upper pulmonary veins (PVs) are responsible for the majority of atrial fibrillation (AF) triggering foci, whereas the inferior PVs are more difficult to ablate and prone to postablation ostial ...

BENGALURU: Though there is considerable public awareness about diseases affecting veins close to the skin, with the most ...

For patients with symptomatic paroxysmal or persistent atrial fibrillation, pulmonary vein isolation results in a significant ...

The pulmonary veins bring oxygen-rich blood from the lungs to the heart, and the coronary arteries supply blood to the heart muscle. The right and left sides of the heart work together.

Pulmonary embolisms usually travel to the lungs from a deep vein in the legs. Doctors call this deep vein thrombosis (DVT). These clots form when the blood can’t flow freely through the legs ...

CHENNAI: Though there is considerable public awareness about diseases affecting veins close to the skin, with the most common ...

About The Study: Pulmonary vein isolation resulted in a statistically significant and clinically important decrease in atrial fibrillation burden at 6 months, with substantial improvements in ...

Free booze and extra pillows might not be the only benefits of flying first class. Known colloquially as “economy class ...

Performing additional catheter ablations targeting diseased myocardium along with the standard approach of pulmonary vein isolation (PVI) to treat persistent atrial fibrillation (AF) does not improve ...

A catheter ablation procedure widely used to treat the most common heart rhythm disorder significantly reduces the burden of ...

During pulmonary vein isolation (PVI) ablation, catheters inserted into the heart deliver radiofrequency energy to destroy tissue on the veins that is causing AF. However, the recurrence of AF ...
