Interdisciplinary management of left ventricular hypertrabeculation/noncompaction during pregnancy with a wearable defibrillator

Usage of the wearable cardioverter-defibrillator during pregnancy

“…A response was received from 112 clinics (87.5%), and eight patients with WCD therapy during pregnancy from three German centers (four patients from Hannover Heart Rhythm Center, Department of Cardiology and Angiology, Hannover Medical School, Hannover, Germany, one patient form Department of Cardiology, University Hospital of Regensburg, Regensburg, Germany and one patient from Department of Cardiology, University Hospital of Freiburg, Freiburg, Germany) and one Austrian center (two patients from Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, Vienna, Austria) were included. One of the patients (patient 7) has been previously published [7] . Initiation of WCD usage was between 05/2015 and 06/2021.…”

“…Application of WCD in pregnancy has, so far, only been reported in few cases [7] , [18] . In none of them, neither appropriate nor inappropriate WCD shocks have been reported.…”

“…Pregnancy is associated with an increased vulnerability for fatal arrhythmias [2] , [3] , [4] . Ventricular tachyarrhythmias in hypertrophic (HCM), dilated (DCM), restrictive (RCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC) and non-compaction (NCCM), can be triggered or aggravated during pregnancy [5] , [6] , [7] , [8] , [9] . Implantable cardioverter-defibrillators (ICD) improve survival in patients with life-threating cardiac arrhythmias.…”

“…So far, experiences with WCD have been reported mainly from women with peripartum cardiomyopathy (PPCM) in the post-delivery period [15] , [16] , [17] , [18] . To our knowledge, application of a WCD during pregnancy has been reported only from 13 patients with PPCM, whose clinical details, however, are not reported and from a patient with NCCM who refused an ICD [7] , [18] .…”

Usage of the Wearable Cardioverter-Defibrillator During Pregnancy

“…Pregnancy is associated with an increased vulnerability for fatal arrhythmias [2][3][4]. Ventricular tachyarrhythmias in hypertrophic (HCM), dilated (DCM), restrictive (RCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC) and non-compaction (NCCM), can be triggered or aggravated during pregnancy [5][6][7][8][9]. Implantable cardioverterdefibrillators (ICD) improve survival in patients with life-threating cardiac arrhythmias.…”
