Cardiac ablation surgery catheters. Catheters and control mechanisms in use at the insertion point during cardiac ablation surgery. Cardiac ablation is a technique that uses catheters inserted into the heart to heat or freeze tissue to ablate (destroy) the tissue to reset the coronary rhythm. This technique is usually used to treat arrhythmia (an irregular heart beat). The catheters are usually inserted at a point in the groin and pushed through the circulatory system to reach the heart. Photographed in the UK.
