Compare RF and cryo ablation in terms of lesion creation and risk profile.

• A. RF forms discrete lesions by heating tissue; Cryo forms lesions by freezing and allows cryomapping with potential tissue adhesion, reducing risk of steam pops and collateral injury
• B. RF forms lesions by freezing; Cryo forms lesions by heating
• C. RF forms continuous lesions; Cryo forms discrete lesions
• D. Cryo cannot be used near critical structures

Answer: (A)
