You feel perfectly alright one moment and the very next you can feel your heart racing at doubling pace. Statistics reveal that atrial fibrillation harms more than two million Americans. Although it accounts for the most common form of arrhythmia, medicines prescribed to get rid of this condition has only had positive effects on 50% of its users. Researchers have, thus, taken upon themselves the task of testing a new tool that would most definitely put a patient's heart back to proper functionality.

Fifty-six year old Tom Calvaresi is the pillar of strength behind his family winery. As a result, when his heart started troubling him, he didn't suppress the problem. “I felt it flutter a bit. Kind of like if you overuse a muscle, you can feel it jumping around a little bit in your arm. Well, I felt this in my chest,” Calvaresi said.

Doctors diagnosed Calvaresi with the condition of atrial fibrillation. This condition basically occurs when the heart's electrical pulses suffer a kind of a “short-circuit,” leading to speed and rhythmic changes in the in the heartbeat. If left not attended to for some time, atrial fibrillation can considerably shoot up the possibility of a heart stroke.

“I have to be able to drink wine in order to be in this business and be at the top of my game, and alcohol is one of the triggers,” says Calvaresi.

In today's day and age, surgeons utilize what is known as a catheter ablation in order to turn the pulmonary vein tissue into scar tissue, so that electrical pulses is unable to get through. Doctors chalk out up to dozens of lesions, which are framed in a dotted pattern around the vein. This method, however, is not always met with straight success.
