Left-ventricular non-compaction (LVNC) is a rare form of cardiomyopathy. Its clinical presentation is highly variable and during pregnancy is frequently associated with heart failure, embolic events, and arrhythmias. Herein we report a case of a woman with left ventricular non-compaction who had an automated defibrillator implantation for recurrent ventricular arrhythmias during pregnancy. During pregnancy and at long-term follow-up no interventions of the device were documented. In conclusion, the management of malignant arrhythmias during pregnancy is one of the concerns for patients with LVNC and requires a careful approach in third-level centers.

Apical Aneurysm

Background: Increasing penetration of high spatial resolution cardiovascular magnetic resonance (CMR) imaging into routine cardiovascular practice has resulted in more frequent identification of a subset of hypertrophic cardiomyopathy (HCM) patients with thin-walled, scarred left ventricular (LV) apical aneurysms. Prior experience involved relatively small numbers of patients with short follow-up and therefore the risk associated with this subgroup remains incompletely defined. Therefore, we assembled a large HCM cohort with LV apical aneurysms and long-term follow-up in order to clarify clinical course and prognosis. Methods and Results: Of 2,400 HCM patients, 60 (2.5%) were identified by CMR with LV apical aneurysm, 24 to 86 years of age, including 19 (32%) <45 years old; 70% male, and followed for 5.6 ± 3.5 years. Over the follow-up period, 24 patients experienced 31 adverse disease-related complications including: appropriate implantable cardioverter-defibrillator discharge for VT/VF (n=11), received or listed for heart transplant (n=6), heart failure death (n=5), nonfatal thromboembolic events (n=4), resuscitated out-of-hospital cardiac arrest (n=3), and sudden death (n=2). In addition, an intracavitary thrombus was identified in the apical aneurysm in 9 patients without a thromboembolic history. Combined HCM-related death and aborted life threatening event rate was 8.6% per year, nearly 6-fold greater than the 1.5% annual mortality rate reported in the general HCM population. Conclusions: Patients with LV apical aneurysms represent a high-risk subgroup within the diverse HCM spectrum, associated with substantial increased risk for disease-related morbidity and mortality, including advanced heart failure, thromboembolic stroke and sudden death. Identification of this unique HCM phenotype should prompt consideration for primary prevention ICD, and anticoagulation for stroke prophylaxis.

Abstract Background Heart failure is becoming the most prominent cause of death among patients with Duchenne Muscular Dystrophy (DMD) and end-stage cardiomyopathy (CMP). Implantation of left ventricular assist devices (LVAD) as destination therapy (DT) in this group of patients is still matter of debate. No current data are available on long-term follow- up of young patients. Purpose The aim of this study was to evaluate the long-term outcome of LVAD in DMD end stage heart failure (HF) compared to a group treated optimal medical treatment (OMT) with inotropes Methods All patients affected by DMD patients presenting with end-stage HF receiving OMT or LVAD have been reviewed. All data about characteristics of HF at presentation including assessment of nutritional status and respiratory function, left ventricular ejection fraction, brain natriuretic peptide, serum sodium, in-hospital treatment and long term follow up have been collected. OMT group was constituted by 4 patients matching implantation VAD criteria but not eligible or refusing treatment. Survival was represented by Kaplan Meier analysis. Results A total of 12 DMD patients with end-stage CMP were considered for this analysis. 8 have been implanted with LVAD during the period from 2011 until mid-2017 and compared with 4 treated with OMT. Mean systolic pressure was 103 versus 91 mmHg in those not receiving LVAD (p=0.2), and left ventricular ejection fraction at the time of presentation was 16‰ for LVAD group and 22‰ for the second group (p=0.1). LVADs improved survival throughout follow-up for patients undergoing baseline inotropic infusions (P=0.0014); for the LVAD group versus the OMT group, 1-month survival was 100‰ and 67‰ respectively and 2-month survival was 100‰ versus 0‰. For LVAD group survival was 86‰ at one year, 71‰ at 2 years and 48‰ at 5 years from implantation. Analysis on short and long-term follow-up showed significant improvement of survival in DMD patients treated with LVAD (log rank<0.001), with a 5-year increase in life expectancy. Conclusions LVAD improved outcomes in patients with LVAD when compared to those without. Long-term follow-up was similar to DT LVAD adult population. Further studies are necessary to confirm these data.

Abstract Funding Acknowledgements Type of funding sources: None. Background  The number of patients who received left ventricular assisted device (LVAD) implantation because of end-stage heart failure has been increasing. In those patients, ventricular arrhythmias (VAs) occur commonly, and electrical storm (ES) and shock therapies by implantable cardioverter-defibrillator (ICD) are considered to increase mortality. Although it is important to identify patients with higher risk of VA events, there have been limited data reporting the risk of VAs in LVAD patients during long-term follow up, especially in non-ischemic cardiomyopathy (NICM). Purpose  We sought to clarify the predictors of ICD therapies in LVAD patients diagnosed as NICM during long-term follow up. Methods We retrospectively analyzed non-ischemic heart failure patients whom a continuous flow LVAD was implanted as a bridge to transplantation therapy from July 2011 to February 2019. ICD programming was generally set as follows; one zone setting (VF zone with maximum shocks) for primary prevention or two zone setting (VF with maximum shocks and VT with ATPs and shocks) for secondary prevention. ICD settings were generally unchanged after LVAD implantation. Clinical and echocardiographic data were collected before and 3 months after LVAD implantation. Device interrogation was performed every 4 - 6 months at out-patient clinic. Patients were followed until May 2019. Results A total of 25 patients were included in the study. The mean age was 49 years, 88% were men. They majority of patients (52%) were diagnosed as idiopathic dilated cardiomyopathy. During the median follow up duration of 889 days (IQR 546 – 2070), 27 appropriate shock events occurred in 7 patients and 154 appropriate ATP-only events in 10 patients. The group with appropriate ICD event (11 patients, 44%) had significantly smaller LVDd (65.2 ± 4.0 vs. 79.4 ± 3.5 mm; p = 0.01) and higher LVEF (26.2 ± 1.6 vs. 20.5 ± 1.4 %; p = 0.02) before LVAD implantation. When patients were divided into 2 groups based on the median value (70.0 mm) of LVDd before LVAD implantation (pre LVDd), patients with smaller pre LVDd (≤ 70mm) had significantly higher rate of appropriate ICD treatment than those with larger pre LVDd (&gt; 70 mm) (Log-rank p &lt; 0.01). In univariate cox regression analysis, pre LVDd was negatively associated with appropriate ICD therapy (hazard ratio 0.94, 95% confidence interval 0.88 - 0.99; p = 0.02). Conclusion Smaller LVDd before LVAD implantation might be a possible predictor of appropriate ICD treatment in patients with NICM. Abstract Figure.

Background: Sacubitril/valsartan decreased the risk of sudden cardiac death (SCD) in patients suffering from heart failure with reduced ejection fraction (HFrEF). However, long-term data are sparse. Objective: The aim of the present study was to compare the incidence of life-threatening arrhythmias consisting of ventricular tachycardia and/or ventricular fibrillation before and after initiation of sacubitril/valsartan treatment. Methods: Out of 12,000 patients with HFrEF from 2016–2018, 148 patients were newly prescribed sacubitril/valsartan, but the long-term data of only 127 patients were available and included in this study. Results: Patients with an average age of 66.8 ± 12.1 had a median left ventricular ejection fraction (LVEF) of 25% (interquartile range (IQR) 5.00–45.00) and 30% (IQR 10.00–55.00, p < 0.0005) before and after sacubitril/valsartan treatment, respectively. Systolic blood pressure decreased from 127.93 ± 22.01 to 118.36 ± 20.55 mmHg (p = 0.0035) at 6 months of follow-up. However, in 59 patients with a long-term outcome of 12 months, ventricular arrhythmias persistently increased (ventricular fibrillation from 27.6 to 29.3%, ventricular tachycardia (VT) from 12% to 13.8%, and nonsustained VT from 26.6 to 33.3%). Conclusions: Sacubitril/valsartan does not reduce the risk of ventricular tachyarrhythmias in chronic HFrEF patients over 12 months of follow-up.

Abstract Background While the beneficial effects of cardiac resynchronization therapy (CRT) have been widely investigated soon after CRT implantation, relatively few data are available on long-term clinical outcomes of CRT recipients. Aim To investigate long-term outcomes of CRT patients with non-ischemic dilated cardiomyopathy stratified as responders and non-responders according to radionuclide angiography. Methods Consecutive heart failure patients with non-ischemic dilated cardiomyopathy undergoing CRT implantation at our University Hospital between 2007 and 2013 were enrolled. All patients were assessed with equilibrium Tc99 radionuclide angiography at baseline and after 3 months of CRT. Left ventricular (LV) ejection fraction was computed on the basis of relative end-diastolic and end-systolic counts, and intraventricular dyssynchrony was derived by Fourier phase analysis. Response to CRT was defined by an absolute increase in LV ejection fraction (LVEF) ≥5% at 3-month follow-up. Clinical outcome was assessed after 10 years through hospital records review. Results Forty-seven patients (83% men, 63±11 years) were included in the study. At 3 months, 25 (53%) patients were identified as CRT responders according to LVEF increase (from 26±8 to 38±12%, p&lt;0.001). In these patients, LV dyssynchrony decreased from 59±30° to 29±18° (p&lt;0.001). Twenty-two (47%) patients were defined as non-responders. No significant changes in LVEF and LV dyssynchrony (50±30° vs. 38±19°, p=0.07) were observed in non-responders. At long-term follow-up (11±2 years), all-cause and cardiac mortality rates were 24% and 12% in responders vs. 32% and 27% in non-responders, respectively (p=ns). Heart transplantation was performed in 3 patients. One (4%) patient among CRT responders compared with 6 (27%) patients among non-responders died of worsening heart failure (p=0.03). Conclusions Although late overall mortality of non-ischemic CRT recipients was not significantly different between mid-term responders and non-responders, CRT responders were at lower risk of worsening heart failure death.
