Case Report: Pulmonary Vein Isolation as a Tailored Treatment for Recurrent Ventricular Tachycardia During Hemodialysis in a Patient With Right Coronary Artery Chronic Total Occlusion. Front Cardiovasc Med 2022; 9:871386. [PMID: 35707126 PMCID: PMC9189425 DOI: 10.3389/fcvm.2022.871386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 04/27/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundCatheter ablation of the ventricular substrate can reduce ventricular tachycardia (VT) recurrence and mortality in an electrical storm (ES). However, identification and specific treatment of plausible triggers is mandatory and may lead to the resolution of ES.ObjectiveThis case presentation seeks to exemplify how pulmonary vein isolation (PVI) may represent a tailored treatment of ES in cases of ventricular substrate, which only becomes arrhythmogenic during high-rate episodes of paroxysmal atrial fibrillation (PAF).ResultsA 54-year-old male with a history of inferior myocardial infarction (MI) and long-term hemodialysis was referred for repetitive implantable cardioverter-defibrillator (ICD) shocks for apparently scar-related monomorphic VT episodes preceded by PAF initiation strictly during hemodialysis. He had recently undergone ICD implantation for similar episodes of ES preceded by the rapid-ventricular response (RVR) PAF during hemodialysis. The patient had no other history of VTs. Electrocardiogram (EKG) changes occurred exclusively during PAF and suggested functional myocardial ischemia. Coronary angiography demonstrated isolated right coronary artery (RCA) chronic total occlusion (CTO). Cardiac magnetic resonance demonstrated RCA-territory residual myocardial viability and mild LV systolic dysfunction. Surgical revascularization was not feasible due to a history of bilateral above-the-knee post-traumatic amputation and severe calcification of internal mammary (IMA) and radial arteries. Subsequent CTO-percutaneous coronary intervention attempt was unsuccessful. The difficulty of assessing LV-substrate ablation end-points due to the “functional” character of the substrate, which only became arrhythmogenic during hemodialysis-related PAF, was considered. Consequently, PVI was performed rather than VT/VF substrate ablation. Twelve months after PVI, the patient remains free of PAF and VT/VF despite chronic hemodialysis sessions.ConclusionThe ES episodes can be triggered by situational factors, such as RVR-PAF and functional ischemia, during hemodialysis in patients with CTO with otherwise no episodes of VT. Tailored treatment of such factors may lead to long-term VT freedom.

Abstract
Wearable cardioverter defibrillators (WCDs) are external devices capable of continuous cardiac rhythm monitoring as well as automatic detection and defibrillation of potentially life-threatening arrhythmias such as ventricular tachycardia (VT) and ventricular fibrillation (VF). They are an alternative approach for patients when an implantable cardioverter defibrillator (ICD) is not appropriate. Although treatment with ICD is considered highly effective for the primary and secondary prevention of sudden cardiac death (SCD) in high-risk patients susceptible to VT and VF, patients may still experience psychological difficulties such as fear of shock, avoidance of normal behaviors and reduced quality of life. One of these phenomena is phantom shock (PS), which is defined as a perception of having received a shock with no evidence of recorded defibrillation upon device interrogation. While PS has been reported in the ICD literature, to the best of our knowledge, we present the first known case of WCD-related PS. We also present a review of the current literature to explore the prevalence of PS, the factors associated with its pathogenesis and interventional studies aimed at reducing its occurrence. We highlight this case because PS is considered a phenomenon that few recognize, which should be discriminated from real device shocks before clinicians initiate treatment, device reprogramming or device discontinuation. We describe the psychosocial factors associated with PS to emphasize the importance of managing any associated psychiatric disorders and psychosocial factors both before and after initiation of device treatment.

Abstract
Implantable cardioverter-defibrillators have become standard preventive treatment for patients with ventricular arrhythmias and other life-threatening cardiac conditions. The advantages and efficiency of the device are supported by multiple clinical trials and outcome studies, leading to its popularity among cardiologists. Implantation of the device is not without adverse outcomes. Implantable cardioverter-defibrillator placement has been found to lead to negative psychological and psychosocial sequelae such as apprehension to engage in physical activity, chronic anxiety, decreased physical and social functioning, a nagging fear of being shocked by the device, and the development of "phantom shocks." Defined as patient-reported shocks in the absence of evidence that the implantable cardioverter-defibrillator device has discharged, phantom shocks could impact the mental health of those affected. This article reviews the case of Mr. L, a 47-year-old man with ischemic cardiomyopathy who was seen by the psychiatry consultation team while under cardiologic care because he reported that his implantable cardioverter-defibrillator device had been shocking him despite no objective evidence after interrogating the device. A literature review of phantom shocks, their associated symptomatology, and psychological consequences are outlined and discussed.

Abstract
A 77 year old man with a biventricular ICD-pacemaker complained of painful, electric jolts disturbing him nightly from sleep. Extensive work-up including device interrogation revealed no defibrillations or arrhythmia, and he was subsequently diagnosed with phantom shocks (PS). His nightly PS symptoms terminated after starting zolpidem 10 mg each night. To date, literature review reveals fifteen articles reporting 163 phantom shock (PS) cases. PS affects 5-9% of ICD recipients. Risk factors include psychiatric disease, atrial fibrillation, NYHA functional status III or greater, prior shock storm, and intraoperative awareness during ICD placement, with defibrillation threshold testing. This report describes a successful PS intervention, and reviews the current knowledge available in the pathophysiology and treatment of PS.

Abstract
OBJECTIVE The aim of this study was to examine physical and heart rhythm management device malfunction complications after participating in a cardiac rehabilitation program intervention compared with usual care. METHOD This study was a clinical trial of 100 patients. After randomization, intervention group patients received 8 cardiac rehabilitation program sessions for 8 weeks and follow-up phone calls. Each session consisted of exercise training, education, and psychological interventions. Data were collected at 3 points in both groups-baseline and 8 and 12 weeks after the first day of the intervention-using a researcher-designed case report form. Data were analyzed using descriptive and nonparametric tests. RESULTS Of the participants, 59% were men, and the sample was aged 40 to 60 years. At the 8- to 12-week follow-up, there were less physical complications among the cardiac rehabilitation group (P < .001) and no between-group differences in complications related to device malfunction. By heart rhythm device type, cardiac rehabilitation had the greatest efficacy in reducing physical complications in patients with cardioverter/defibrillators. CONCLUSIONS Cardiac rehabilitation reduced physical complications in patients with cardiac rhythm management devices, especially in patients with cardioverter/defibrillators. Cardiac clinical nurse specialists should recommend rehabilitation programs as part of postimplantation rhythm device treatment to decrease the risk of physical complications.

Abstract
OBJECTIVE In this retrospective cross-sectional study, we evaluated the existence of psychiatric symptoms which appeared after implantation of an implantable cardioverter defibrillator (ICD). METHODS Patients with ICDs were diagnosed using the Mini International Neuropsychiatric Interview (MINI) and were excluded if they had any psychiatric diagnosis prior to ICD implantation. Depression and anxiety were evaluated using the HAM-D and HAM-A rating scales and their attitude towards the ICD using a visual analog scale (VAS). Ninety five ICD patients with mean age of 66 years (±11.5) were recruited, 80 (84%) were men. RESULTS Four (4%) patients were diagnosed with new-onset MDD and one patient (1%) with anxiety. Twenty seven (28%) were found to have significant depressive symptoms (HAM-D >8), without MDD diagnosis; half of them attributing these symptoms to the device. Seven (8%) patients experienced phantom shocks and had relatively higher depressive scores (HAM-D 10.3 vs. 5.8; F = 3.696; p = 0.058). The MDD rates in our study were rather consistent with those reported for cardiac patients. CONCLUSIONS We suggest that ICD contributed little, if any, additional depressive or anxiety symptoms after implantation. We found that the overall attitude towards the device was positive and that shocks and phantom shocks were related to depressive symptoms.

Abstract
Athletes with an implantable cardioverter defibrillator (ICD) represent a diverse group of individuals who may be at an increased risk of sudden cardiac death when engaging in vigorous physical activity. Therefore, they are excluded by the current guidelines from participating in most competitive sports except those classified as low intensity, such as bowling and golf. The lack of substantial data on the natural history of the cardiac diseases affecting these athletes as well as the unknown efficacy of ICDs in terminating life-threatening arrhythmias occurring during intense exercise has resulted in the restrictive nature of these now decade old guidelines.

Abstract
AIMS The aim of this randomised clinical trial was to assess a comprehensive cardiac rehabilitation intervention including exercise training and psycho-education vs 'treatment as usual' in patients treated with an implantable cardioverter defibrillator (ICD). METHODS In this study 196 patients with first time ICD implantation (mean age 57.2 (standard deviation (SD)=13.2); 79% men) were randomised (1:1) to comprehensive cardiac rehabilitation vs 'treatment as usual'. Altogether 144 participants completed the 12 month follow-up. The intervention consisted of twelve weeks of exercise training and one year of psycho-educational follow-up focusing on modifiable factors associated with poor outcomes. Two primary outcomes, general health score (Short Form-36 (SF-36)) and peak oxygen uptake (VO₂), were used. Post-hoc analyses included SF-36 and ICD therapy history. RESULTS Comprehensive cardiac rehabilitation significantly increased VO2 uptake after exercise training to 23.0 (95% confidence interval (CI) 20.9-22.7) vs 20.8 (95% CI 18.9-22.7) ml/min/kg in the control group (p=0.004 (multiplicity p=0.015)). Comprehensive cardiac rehabilitation significantly increased general health; at three months (mean 62.8 (95% CI 58.1-67.5) vs 64.4 (95% CI: 59.6-69.2)) points; at six months (mean 66.7 (95% CI 61.5-72.0) vs 61.9 (95% CI 56.1-67.7) points); and 12 months (mean 63.5 (95% CI 57.7-69.3) vs 62.1 (95% CI 56.2-68.0)) points (p <0.05). Explorative analyses showed a significant difference between groups in favour of the intervention group. No significant difference was seen in ICD therapy history. CONCLUSION Comprehensive cardiac rehabilitation combining exercise training and a psycho-educational intervention improves VO₂-uptake and general health. Furthermore, mental health seems improved. No significant difference was found in the number of ICD shocks or anti-tachycardia pacing therapy.
