1.6.2.10 Secondary Endpoint Results
1. The purpose of Secondary Endpoint 1 is to evaluate the
overall ability of the Tupos LV/ATx to appropriately convert
spontaneous AT (atrial tachycardia) and AF (atrial fibrillation).
The results from the OPTION study were compared to the
results from BIOTRONIK’s TACT study (P000009/S4, dated
09-09-2002) that demonstrated the effectiveness of these
atrial therapy features in the Tachos DR - Atrial Tx ICD.
Table 12
summarizes success rates for each individual atrial
tachyarrhythmia therapy type and overall success rate from
the OPTION study compared to the TACT study. The number
of episodes and patients receiving any therapy is less than
the total episodes of each therapy type, as episodes may
have included more than one type of therapy.

HF Burst 17 45 111 40.5%

Shock 42 84 108 77.8 %

The overall conversion rate and the conversion rates for each
therapy are comparable to the conversion rates observed in
the TACT study, demonstrating that the Tupos LV/ATx device
has similar atrial conversion capabilities as the legally
marketed Tachos DR – Atrial Tx ICD.
