What phenomenon is caused by unstable catheter position during RF ablation?

Unstable catheter position during radiofrequency (RF) ablation leads to weak tissue contact. This occurs because the catheter must maintain consistent contact with the target tissue to deliver effective energy for ablation. When the catheter is not stable, it can move away from the desired area, causing inconsistent energy delivery. This weak contact reduces the efficiency of the ablation process and can result in inadequate lesion formation, potentially leading to treatment failures or incomplete ablation. Maintaining a stable position is crucial for ensuring that the energy is deposited effectively within the tissue to achieve the desired therapeutic effect.
