Serious, often life-threatening irregular heartbeats called atrial fibrillation require innovative technology and skilled cardiologists. Cryoablation is an advanced surgical procedure used to treat irregular heartbeats called atrial fibrillation.

Atrial fibrillation

Atrial fibrillation occurs when the heart's two small upper chambers quiver instead of beating in rhythm (arrhythmia, afibrilation or afib). Blood may not get pumped completely out of the chambers, causing it to pool and clot, which could result in a stroke. About 15% of strokes occur in people with atrial fibrillation.


Cryoablation is a unique procedure where a catheter is inserted into the blood vessel (usually the vein in the groin called the femoral vein) and advancing it to the area of the heart responsible for the heart rhythm problem. This tissue is frozen which disables the arrhythmia. 

Cryoablation is very safe and there is very little chance of causing damage to the esophagus and surrounding tissue. Cryoablation reduces procedure times, and better isolates the pulmonary vein resulting in less risk to you, the patient.

Methodist Hospital was the first hospital in the area to offer cryoablation - beginning in 2011.
