Limitations:
- Some, but not all variations in PV number and anatomy were represented
in the study. Accordingly, one should not assume that the accurate
performance achieved in the few patients with PV variations will be
reproduced in patients with more uncommon PV anatomy.
- A major limitation of the study is that the gold standard to define
the accuracy of the LA reconstruction by m-FAM was a visual comparison
with the CTA of the same patient rather than a computerized “pattern
recognition” formal comparison.
- This is a single center study and our center was involved in the early
phases of developments of the m-FAM algorithm. Indeed, we performed
approximately 40 previous cases using the m-FAM as research tool
before initiating the current clinical study. The large experience
with the m-FAM algorithm may have influenced our results.
Nevertheless, our impression is that the learning curve in using the
m-FAM is very short.
