Procedures

166 procedures (1.42/patient) in 2-4 PVs were performed in total, consisting of 117
(71%) primary, 44 (27%) secondary und 5 (2%) tertiary procedures. Figure 1 illustrates the
respective numbers of primary, secondary and tertiary procedures per patient and year (of first
procedure) between 2001 and 2003. In 63 patients (55.8%) a single procedure was carried out, as
opposed to 45 patients (39.8%) with a second and 5 patients (4.4%) with a third ablation
procedure. The duration of the primary procedure lasted for 228±55 min and was significantly
longer in comparison with the secondary (206±56 min, p=0.004). The fluoroscopic time duration
for the primary and secondary procedure accounted for 62±15min, and 53±20min, respectively.
