- W2000904770 abstract "Introduction: We compared the calculated optimal V‐V interval derived from intracardiac electrograms (IEGM) with the optimized V‐V interval determined by invasive measurement of LVdP/dt MAX . Methods and Results: Thirty‐two patients with heart failure (six females, ages 68 ± 7.8 years) had a CRT device implanted. After implantation of the atrial, right and a left ventricular lead, the optimal V‐V interval was calculated using the QuickOpt™ formula (St. Jude Medical, Sylmar, CA, USA) applied to the respective IEGM recordings (V‐V IEGM ), and also determined by invasive measurement of LVdP/dt MAX (V‐V dP/dt ). The optimal V‐V IEGM and V‐V dP/dt intervals were 52.7 ± 18 ms and 24.0 ± 33 ms, respectively (P = 0.017), without correlation between the two. The baseline LVdP/dt MAX was 748 ± 191 mmHg/s. The mean value of LVdP/dt MAX at invasive optimization was 947 ± 198 mmHg/s, and at the calculated optimal V‐V IEGM interval 920 ± 191 mmHg/s (P < 0.0001). In spite of this significant difference, there was a good correlation between both methods (R = 0.991, P < 0.0001). However, a similarly good correlation existed between the maximum value of LVdP/dt MAX and LVdP/dt MAX at a fixed V‐V interval of 0 ms (R = 0.993, P < 0.0001), or LVdP/dt MAX at a randomly selected V‐V interval between 0 and +80 ms (R = 0.991, P < 0.0001). Conclusion: Optimizing the V‐V interval with the IEGM method does not yield better hemodynamic results than simultaneous BiV pacing. Although a good correlation between LVdP/dt MAX determined with V‐V IEGM and V‐V dP/dt can be constructed, there is no correlation with the optimal settings of V‐V interval in the individual patient." @default.
