Hemodynamics Measurement in Radiofrequency Catheter Ablation

After completion of ablation, the ablation catheter will be serially positioned in the cardiac chambers (either the left or right side of the heart). The stop cock will be turned to the pressure transducer and waveforms will be stored corresponding to each chamber.

After removal of the irrigated ablation catheter, a 5F balloon tipped PA catheter which will be positioned under fluoroscopic guidance in each previously evaluated chamber and the chambers will be measured again.
