Clinical implications
Despite the frequency of the SVC having non-PV foci and the opportunity to perform an SVCI, few studies have considered the optimal AI values for the SVCI. This study showed that an AI value of 350 may be a new indicator of the need for an SVCI. We also showed that the amplitude of the anterior and septal walls was higher than that of the other segments. This information could be useful for a safe and effective SVCI.
