Abstract Background  Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a severe genetic arrhythmogenic disorder characterized by adrenergically induced ventricular tachycardia manifesting as stress-induced syncope and sudden cardiac death. While CPVT is not associated with dilated cardiomyopathy (DCM) in most cases, the combination of both disease entities poses a major diagnostic and therapeutic challenge. Case summary  We present the case of a young woman with CPVT. The clinical course since childhood was characterized by repetitive episodes of exercise-induced ventricular arrhythmias and a brady-tachy syndrome due to rapid paroxysmal atrial fibrillation and sinus bradycardia. Medical treatment included propranolol and flecainide until echocardiography showed a dilated left ventricle with severely depressed ejection fraction when the patient was 32 years old. Cardiac magnetic resonance imaging revealed non-specific late gadolinium enhancement. Myocardial inflammation, however, was excluded by subsequent endomyocardial biopsy. Genetic analysis confirmed a mutation in the cardiac ryanodine receptor but no pathogenetic variant associated with DCM. Guideline-directed medical therapy for HFrEF was limited due to symptomatic hypotension. Over the next months, the patient developed progressive heart failure symptoms that were finally managed by heart transplantation. Discussion  Management in patients with CPVT and DCM is challenging, as Class I antiarrhythmic drugs are not recommended in structural heart disease and prophylactic internal cardioverter-defibrillator implantation without adjuvant antiarrhythmic therapy can be detrimental. Regular echocardiographic screening for DCM is recommendable in patients with CPVT. A multidisciplinary team of heart failure specialists, electrophysiologists, geneticists, and imaging specialists is needed to collaborate in the delivery of clinical care.

Recent Advances

Background : We previously described severity of heart failure and ventricular tachycardia (VT) as independent predictors of mortality in patients with cardiac sarcoidosis (CS). Medical treatment for chronic heart failure has been established over the last few decades. Prophylactic use of implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy (CRT or CRT-D) have been introduced in patients with severe heart failure. We therefore hypothesized that the prognosis of CS improves due to such advances in the management of heart failure and VT. Methods : To confirm our hypothesis, we analyzed 43 CS patients diagnosed between 1988 and 2006 and treated with corticosteroids. We classified two sequential referral patients diagnosed between 1988 and 1997 (n=19) and between 1998 and 2006 (n=24), and compared treatment and prognosis between the two cohorts. Results : Left ventricular ejection fraction (LVEF) and dimensions were similar between the two cohorts. Although age in the 1988–1997 referral cohort was significantly younger than that in the 1998–2006 referral cohort (54±14years versus 62±10years, p<0.05), survival in the earlier cohort was significantly worse (log-rank=4.41, p<0.05). The 1- and 5-year mortality rates were 88% and 71% in the 1988–1997 referral cohort, and 96% and 92% in the 1998–2006 referral cohort, respectively. The 1998–2006 referral cohort showed significantly higher incidence of ICD or CRT-D implantation (29% versus 6%, p<0.05), β-blocker use (46% versus 6%, p<0.01) and addition of methotrexate (21% versus 0%, p<0.05), and increased maintenance dose (7.0±1.9mg/day versus 5.0±0.9mg/day, p<0.01) compared to the 1988–1997 referral cohort. Multivariate analysis including age, LVEF, and sustained ventricular tachycardia (sVT) identified diagnosis between 1988 and 1997 (hazard ratio [HR]: 19.8, p<0.01) and LVEF (HR: 0.83/1% increase, p<0.01) as independent predictors of mortality. Conclusions : Survival in the recent CS patients is significantly better than previously described. Recent advances in the device therapies and medical treatments including modified immunosuppression alter the clinical outcome in patients with CS.

Vt Ablation

Introduction: Ventricular tachycardia (VT) is a significant cause of morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF). Hypothesis: Data on efficacy, safety, and outcomes of catheter ablation for VT in HFrEF have not been studied well. Methods: The 2002-2014 Nationwide Inpatient Sample (NIS) was used to identify all hospitalizations with a principle diagnosis of VT (International Classification of Diseases, Ninth Edition, Clinical Modification [ICD-9-CM] code 427.1) and a secondary diagnosis of HFrEF. Patients who underwent catheter ablation were identified using ICD-9-CM procedure code 37.34. Results: Of 228,557 patients with HFrEF & VT, 5845 (2.56%) underwent catheter ablation. The prevalence of Diabetes Mellitus (DM) and Chronic Kidney disease (CKD) was higher in the reference population contrary to a higher prevalence of prior myocardial infarction (MI), coronary bypass and AICD in those undergoing CA. The frequency of complications in the ablation group was 19.47%, the most common being post-operative hemorrhage (8.3%). This was followed by myocardial infarction (5.34%), pericardial complications (3.38%), and neurological complications (2.14%) (Figure 1.). The odds of in-hospital mortality were lower in the CA group compared to the reference group (5.08% vs 9.42%, p<0.05). Conclusions: Compared to medical therapy, VT ablation in HFrEF is associated with lower mortality though with significant complication rate. This suggests a need for future studies identifying the safety measures in VT ablations and instituting appropriate interventions to improve overall VT ablation outcomes.

Icd Implantation

Introduction: Implantable cardioverter defibrillator (ICD) implantation in patients with cardiac amyloidosis is controversial, with no clear guidelines for clinical decision-making.. The role of ICD implantation in hereditary Transthyretin Amyloid Cardiomyopathy (hATTR-CM) is unclear. We sought to establish the burden of ventricular arrhythmias and the outcomes of ICD implantation in a single center cohort of hATTR-CM patients. Methods: A total of 69 patients with a confirmed diagnosis of hATTR-CM from genetic testing, and technetium pyrophosphate (PYP) scanning, or endomyocardial biopsy underwent retrospective chart review for demographic, clinical, and arrhythmia data. Results: Seventy-four percent of the cohort was male, with a mean age at diagnosis of 68 (SD=18 years). Sixty-five patients (94.2%) patients were African-American; all of whom carried the Valine 122 Isoleucine mutation. Most had systolic heart failure (New York Heart Association Staging II [18, 26%] and III [40, 58.8%]); 37 (54%) patients had an LVEF ≤ 35%. Thirty-six (52.2%) patients had documented episodes of non-sustained ventricular tachycardia (NSVT), three (4.3%) with ventricular tachycardia (VT), and one (1.5%) with ventricular fibrillation (VF). A total of 15 (21.7%) patients had ICDs placed for prevention of sudden cardiac death in the setting of low LVEF (EF <35%). All recorded VT/VF episodes occurred in three patients with ICDs. Of these patients, one experienced two episodes of VT each successfully abated by antitachycardia pacing (ATP), another experienced a single episode of VT abated by ATP, while the final experienced VF with successful 36J shock as well as two episodes of VT each successfully treated with 36J shocks. No inappropriate ICD shocks were delivered, however, there were two instances of ATP for inappropriately detected atrial arrhythmias. Conclusions: In a cohort of patients with hATTR-CM, we observed a high incidence of NSVT, yet only 41% of patients with severe systolic heart failure had ICDs implanted. A high rate of successful defibrillation and no inappropriate ICD shocks were noted, suggesting that ICDs should be strongly considered, and may be underutilized, in patients with systolic heart failure and/or arrhythmias in the setting of hATTR-CM.

Diagnostic Work

Cardiac arrhythmias are more common in subjects with diabetes mellitus (DM) than in their counterparts without diabetes. Atrial fibrillation (AF) is present in 10–20% of the DM patients, but the association between DM and AF is mostly due to co-morbidities of DM patients increasing the vulnerability to AF. When type 2 DM and AF coexist, there is a substantially higher risk of cardiovascular mortality, stroke, and heart failure, which indicates screening of AF in selected patients with DM. Anticoagulant therapy either with vitamin K antagonists or non-vitamin K antagonist oral anticoagulants is recommended for DM patients with either paroxysmal or permanent AF, if not contraindicated. Palpitations, premature ventricular beats, and non-sustained ventricular tachycardia are common in patients with DM. The diagnostic work-up and treatment of these arrhythmias does not differ between the patients with or without DM. The diagnosis and treatment of sustained ventricular tachycardia, either monomorphic or polymorphic ventricular tachycardia, or resuscitated ventricular fibrillation is also similar between the patients with or without DM. The risk of sudden cardiac death is higher in DM patients with or without a diagnosed structural heart disease. Patients with diabetes and a left ventricular ejection fraction less than 30–35% should be treated with a prophylactic implantable cardioverter defibrillator according to current guidelines. Beta-blocking therapy is recommended for DM patients with left ventricular dysfunction or heart failure to prevent sudden cardiac death due to arrhythmia.
