Introduction: The wearable cardioverter defibrillator (WCD) has been used to protect AMI patients with reduced LVEF (≤35%) until ICD evaluation is recommended. The rate of EF improvement (e.g. EF>35%) over the initial 8-12 weeks after AMI has not been reported. METHODS: The manufacturer-maintained registry was searched for AMI patients who received a WCD shock for VT/VF between 05/2008 and 02/2013. The treated group was matched (1: ~4) with event-free WCD patients by ICD-9 code (410.*), gender, age and prescription date. Chart notes were reviewed for clinical characteristics. Follow-up was assessed through the registry and Social Security Death Master File. RESULTS: There were 992 (age=63±12, female=20.2%) AMI patients included in the final analysis, 206 treated by WCD and 786 event-free patients. Median follow-up was 334 days. Mean length of WCD use was 67±506 (median=38) days. Subgroup clinical characteristics are presented in Table 1. In the event-free group, 289 (38.9%) patients showed EF improvement to >35%. Nine (4.5%) in the treated group continued wearing the WCD until EF recovery, while 125 (60.7%) received ICD. Absence of recorded heart failure and/or diabetes were associated with LVEF recovery (p<.0001). CONCLUSION: In our study, almost 40% of AMI patients with initial EF ≤35% had EF improvement in two months. The EF recovery group had lower rates of heart failure and diabetes. WCD allows time for left ventricular function recovery in low EF post MI patients, optimizing ICD implantation decisions.

Abstract Background The implantation of cardioverter defibrillators (ICDs) is an established therapy in the prevention of sudden cardiac death in patients with systolic dysfunction after myocardial infarction. To avoid immediate implantation of an ICD, wearable cardioverter defibrillator vests (WCD) can be used to protect patients against malignant rhythm disorders, while at the same time drug-based heart failure therapy has to be initiated. This drug therapy can improve left ventricular ejection fraction and primary prophylactic cardioverter defibrillator implantation may not be necessary. However, the recent Vest Prevention of Early Sudden Death Trial (VEST) questioned the regular use of the WCD in this setting. Case presentation A 47-year-old Caucasian man with severely impaired left ventricular function early after myocardial infarction was prescribed a WCD as primary prophylaxis to prevent sudden cardiac death. Seven days after the patient was supplied with a WCD, the patient suffered from an electrical storm with recurrent ventricular tachycardia (VT), which was successfully terminated 17 times by the WCD. On coronary angiography, the formerly infarct-related right coronary artery had TIMI (Thrombolysis in Myocardial Ischemia Trial) III flow, and a remaining stenosis in the left anterior descending artery (LAD) was stented, which did not stop recurrent VT. In the electrophysiology (EP) study, a focus was mapped in the left inferior ventricle, which was ablated. This stopped the VT. A second radio-frequency (RF) ablation in the same area was necessary after 14 days. Finally, a permanent cardioverter defibrillator was implanted. Conclusion We report the case of a patient who survived recurrent episodes of VT early after myocardial infarction by effective defibrillation with a WCD. The WCD is a useful device to bridge time until a final decision for implantation of a defibrillator.

Peripartum cardiomyopathy is an unusual and uncommon form of dilat­ ed cardiomyopathy that is often fatal to young women, the cause of which is unknown. Diagnostics is difficult and requires vigilance. The treatment does not differ from other forms of heart failure. Fetal outcome, however, is quite good. Maternal outcomes depend on 2–6 months recovery of the left ventricular function. We describe a previously asymptomatic patient who presented with pulmonary edema one day after caesarean section. In this case the solution was favorable to the patient. Complete recovery of the left ventricular function happened earlier than indicated in litera­ ture.
