MitraClip detachment after electrical cardioversion: a case report.

Transcatheter edge-to-edge repair is a well-established method for treating severe MR in patients who are not suitable for surgical intervention. However, complications can arise during or after the procedure, such as clip detachment as in this case. Several mechanisms can explain SLD. We presumed that in the current case, immediately after cardioversion, there was an acute (post-pause) increase in left ventricle end-diastolic volume and thus in the left ventricle systolic volume with more vigorous contraction, possibly pulling apart the leaflets and detaching the freshly applied TEER device. This is the first report of SLD related to electrical cardioversion after TEER. Even though electrical cardioversion is considered safe, SLD can occur in this setting.
