EPS and attempted ablation<br />
• TV annulus remapped with SRO sheath, F curve cool tip catheter<br />
• AF spontaneously induced with degeneration to VF – cardioverted<br />
to SR<br />
• Prolonged mapping at TV annulus with early signals at 6 o’clock.<br />
• Multiple ablations with occasional suggestion <strong>of</strong> a change in the<br />
degree <strong>of</strong> pre-excitation.<br />
• Good signals up to 40 msec ahead <strong>of</strong> delta over a reasonably wide<br />
area.<br />
• Eventually exchanged SR0 for an Agilis sheath to get better contact<br />
and perform<br />
• Further ablation without success.
