Systems and methods of ablating cardiac tissue

A method to treat paroxysmal atrial fibrillation, the method comprising:

• ablating tissue of one or more targeted pulmonary veins with one or more of a plurality of electrodes of a radiofrequency balloon catheter;
• and
• determining a single shot pulmonary vein isolation (PVI) success rate based on a plurality of ablation parameters of the radiofrequency balloon catheter before ablating or after ablating.

A method to treat paroxysmal atrial fibrillation, the method comprising:

• controlling power delivered to one or more of a plurality of electrodes in connection with ablating organ tissue;
• and
• determining a single shot PVI success rate based on a plurality of ablation parameters of one or more plurality of electrodes.

A method, comprising:

• determining a single shot pulmonary vein isolation (PVI) success rate based on at least one ablation parameter of one or more of a plurality of electrodes of a radiofrequency balloon catheter.
