Abstract
Abstract
A 22–year–old healthy athlete was referred to our hospital for electrocardiographic findings consistent with intermittent type–1 Brugada pattern. A routine electrocardiogram (ECG) performed during a check–up showed sinus rhythm, normal PR interval and QRS duration, rSR’ with a coved type ST–segment elevation in V2 lead (Figure 1).The patients denied history of syncope or palpitations and his family history did not show sudden cardiac death or Brugada syndrome (BrS). Transthoracic echocardiography was normal and a 12–lead Holter monitoring revealed the intermittence of the type–1 Brugada pattern. The patient was hospitalized for further investigation. On admission, ECG showed a type–2 Brugada pattern; therefore, Ajmaline challenge test (1 mg/kg injection in 10 minutes) was performed and resulted positive. Subsequently, the patient underwent an electrophysiological study (EPS) which was negative for induction of sustained arrhythmias. The protocol adopted consisted of double extrastimuli programmed electrical stimulation until refractoriness (drive 600/220 ms and 400/210 ms), at double sites (right ventricle apex and right ventricular outflow tract). Furthermore a genetic test was performed using next–generation sequencing, showing a heterozygous mutation in the SCN5A gene, encoding for sodium channel alpha subunit (variant c.5363delA), not previously described in the literature. Since the low arrhythmic risk, the patient was implanted with a loop recorder (ILR, Medtronic Reveal LINQ), entering a program of home monitoring. After a 15–months follow–up, an episode of ventricular polymorphic tachycardia lasting 2 minutes and 11 seconds, associated with lightheadedness and palpitations, was detected by the remote monitoring (Figure 2). The patient was therefore hospitalized. During the in–hospital stay a cardiac magnetic resonance was performed to exclude other underlying diseases, identifying an enlarged right ventricle (EDVi 114 ml/m2) and abnormal free wall motion (Figure 3), thus reaching one major criteria of arrhythmogenic cardiomyopathy (however not sufficient for the diagnosis). The patient was then implanted with a subcutaneous implantable cardiac defibrillator (Boston Scientific EMBLEM MRI S–ICD). We presented a case of complex arrhythmic risk stratification in a possible overlap of an arrhythmogenic cardiomyopathy and a Brugada Syndrome in a young athlete who experienced a sustained ventricular tachycardia during loop–recorder monitoring.

Abstract
Abstract
Background
Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg–Strauss, is a rare multisystem disorder characterized by chronic rhinosinusitis, asthma, and prominent peripheral blood eosinophilia (PE). Cardiac involvement may include eosinophilic myocarditis and it is a serious manifestation of EGPA.
Case Presentation
A 67–year–old woman presented to the emergency department with 2–weeks history of dyspnea, orthopnea and asthenia. She had history of asthma, PE, adjuvant radiotherapy after right mastectomy (July 2021). The patient was diagnosed with new onset atrial fibrillation in the previous month. At admission, the patient was hemodynamically stable and with signs of congestion. Complementary exams showed sinus rhythm and T–wave inversion on lateral leads; PE (2010/uL), elevated troponin and BNP values; and severe biventricular systolic dysfunction with diffuse hypokinesia and apical akinesia. The patient was admitted to the ICU and was treated with intravenous diuretics and levosimendan. Optimal HF therapy was introduced. Serial echocardiography revealed partial recovery of LVEF and blood analysis showed a decrease in troponin levels, with persistent eosinophilia (6330/uL). Computed tomography (CT) excluded significant coronary disease, and showed bilateral basal ground–glass opacities, areas of air–space consolidation and bilateral reticular–nodular pattern. Cardiac magnetic resonance revealed increased T2 values/signs of myocardial edema in anterior wall, interventricular septum and apex and no late gadolinium enhancement, compatible with myocarditis. An endomyocardial biopsy (EMB) was performed and confirmed the diagnosis of eosinophilic myocarditis. Oral corticosteroids were started. Paranasal CT scan showed signs of chronic sinusitis, without polyposis, and antineutrophil cytoplasmic antibodies were positive, making the diagnosis of EGPA, according to ACR criteria.
Discussion
In a patient presenting with new onset heart failure and with history of asthma and eosinophilia, it is important to suspect eosinophilic myocarditis, as this is a rare but reversible life–threatening condition. EMB plays an important role in the diagnosis and should be done promptly.
Conclusion
We described a multidisciplinary management of a case of a patient with eosinophilic myocarditis and EGPA, presenting with severe acute biventricular dysfunction.

Abstract
Background The rate of post–vaccine myocarditis is being studied from the beginning of the massive vaccination campaign against Sars–Cov–2, reporting a very low incidence. Although a direct cause–effect relationship has been described, in most cases the vaccine pathophysiological role is doubtful. Moreover, it is not quite as clear as having had a previous myocarditis could be a risk factor for a post–vaccine disease relapse. Case Presentation A 27–year–old man presented to the ED for palpitations and pericardial chest pain radiated to the upper left limb, on the 4th day after the third dose of BNT162b2 vaccine. He experienced a previous myocarditis 3 years before, with full recovery and no other comorbidities. ECG showed a diffuse ST segment elevation and a cardiac echo showed lateral hypokinesia with preserved ejection fraction. Troponine–T was elevated (160ng/l), chest x–ray was normal, and the Sars–Cov–2 molecular buffer was negative. High–dose anti–inflammatory therapy with ibuprofen and colchicine was started; in the 3rd day high sensitivity Troponin I reached a peak (hsTnI) of 23000 ng/L. No heart failure or arrhythmias were observed. A cardiac MRI was performed showing normal biventricular systolic function, areas of LGE with non–ischemic subepicardial pattern at the level of the anterior wall with increased T2 signal, suggestive for a recurrence of myocarditis. A left ventricle electroanatomic voltage mapping was negative (both unipolar and bipolar), while the endomiocardial biopsy showed a picture consistent with active myocarditis. The patient was discharged in good shape, with normal hsTnI values on bisoprolol 1.25mg, ramipril 2.5mg, ibuprofen 600 mg three times a day, colchicine 0.5 mg twice a day. Discussion: We presented the case of a young man with history of previous myocarditis, admitted with a non–complicated acute myopericarditis relapse occurred 4 days after Sars–Cov–2 vaccination (3rd dose). Despite the observed very low incidence of cardiac complications following BNT162b2 administration, and the lack of a clear proof of a direct cause–effect relationship, we think that in our patient this link can be more than likely. In the probable need for additional Sars–Cov–2 vaccine doses in the next future, studies addressing the risk–benefit balance of this subset of patient are warranted. Conclusion We described a multidisciplinary management of a case of myocarditis recurrence after the third dose of Sars–Cov–2 BNT162b2 vaccine.

Abstract
Abstract
Background
Current arrhythmogenic right ventricular cardiomyopathy (ARVC) diagnostic criteria are mostly based on ventricle function and dimension. Previous studies have reported a significant overlap between ARVC and chronic myocarditis, at non-invasive assessment.
Purpose
Tto compare biopsy-proven ARVC and myocarditis patients, in order to identify clinical, imaging and invasive electroanatomic voltage mapping (EVM) differences between the two groups.
Methods
Patients with borderline diagnosis of ARVC or suspected myocarditis underwent compete assessment with cardiac magnetic resonance (CMR). All patients underwent endomyocardial biopsy (EMB) with targeted tissue sampling guided by EVM. All patients with an histological diagnosis of myocarditis or ARVC were included.
Results
83 patients were included, divided into 35 (42.2%) ARVC and 48 (57.8%) myocarditis. Among ARVC patients, 25 (71.4%) had right dominant ARVC, 5 (14.3%) left dominant patter and 5 (14.3%) bi-ventricular involvement. Nine patients (23.1%) with suspected clinic diagnosis of ARVC before EMB, received and histological diagnosis of myocarditis. Two (5.7%) patients with suspected myocarditis were proven to have ARVC. When comparing patients with ARVC and patients with myocarditis, univariate analysis showed that age, sex, family history, arrhythmic disorders at presentation and ECG abnormalities were similar between the two groups (P>0.05 for all the variables). There was also no significant difference with regards to bi-ventricular function and dimension at CMR evaluation. More patients with myocarditis resulted positive at late gadolinium enhancement (LGE) evaluation, although non-significantly (P=0.082). Oedema was more frequently present in patients with myocarditis (P=0.01), while adipose tissue infiltration and segmental wall motion abnormalities were more often observed in patients with ARVC (P=0.002 and P<0.001 respectively). At EVM analysis, a significant greater number of patients had a pathological uni- and bi-polar EVM (P<0.05 in all cases) and the scar-area was greater in patients with ARVC: 18.8 vs 11.0 cmq (P=0.041).
Conclusion(s)
A significant number of patients who received a clinical diagnosis of Myocarditis or ARVC according to current guidelines, were subsequently reclassified after histological analysis. Patients with ARVC and myocarditis were not distinguishable on the basis of clinical features and ventricular function and dimensions. Conversely, tissue analysis with CMR demonstrated how patient with ARVC had less oedema, more adipose tissue infiltration and had more extensive scar at EVM evaluation.

Abstract
Abstract
Background
Electroanatomic voltage mapping (EVM) is a promising modality for guiding Endomyocardial biopsies (EMB). Previous experiences on this techniques have reported safety and feasibility of this approach. These reports however, resulted limited by sample size or imperfect designs, preventing reliable comparisons of the effectiveness of this new methods with a conventional or a cardiac magnetic resonance (CMR) imaging guided approach.
Aim
We now report the largest cohort of patients undergoing EVM-guided EMB in order to show its diagnostic yield and comparing it with a cardiac magnetic resonance (CMR) guided approach.
Methods
One-hundred and sixty-two consecutive patients undergoing EMB at our Institution from 2010 to 2019 were included. Pathological areas identified at EVM and CMR underwent EMB. According to EMB results, CMR and EVM sensitivity and specificity regarding the identification of pathological substrates of myocardium were evaluated.
Results
A gadolinium-enhanced CMR had been performed in 143 (88.9%) of the population and yielded pathological findings in 121 (85.8%) of such cases. Late gadolinium enhancement (LGE) was present in 94 (70%) of the patients, while EVM identified areas of low voltages in 61%. Right (73%), left (19%) or both ventricles (8%) underwent sampling. EVM proved to have similar sensitivity to CMR (74% vs. 77%; P=0.479), with non-significantly higher specificity (70% vs. 47% P=0.738). In 12 patients with EMB-proven cardiomyopathy, EVM identified pathological areas, which had been undetected at CMR evaluation (concordance rate 53.8%; k = 0.26). Sensitivity of pooled EVM and CMR was as high as 95%. Five cases (3,8%) of cardiomyopathies were undetected by both CMR and EVM. Complications rate was low (4,9%), mostly vascular access related, with no patients requiring urgent management.
Conclusion
EVM proved to be a promising tool for targeted-EMB due to its sensitivity and specificity in identifying myocardial pathological substrates. EVM demonstrated to have an accuracy similar to CMR. EVM and CMR together conferred EMB a positive predictive value of 89%.

Abstract
Abstract
Background
A myocardial substrate assessment through percutaneous endomyocardial biopsy (EMB) represents an important additional diagnostic test for cardiomyopathies when uncertainties remain after non-invasive evaluation. Yet, extensive application of EMB has been limited by the low sensitivity of biopsies. Electroanatomic voltage mapping (EVM) is a promising modality for guiding Endomyocardial biopsies (EMB).
Aim
The aim of our study is to evaluate the diagnostic yield of EVM-guided EMB and the role of histological analysis in the diagnosis of patients with suspected cardiomyopathies and arrhythmic presentation.
Methods
One-hundred and sixty-two consecutive patients undergoing EMB at our Institution from 2010 to 2019 were included. Demographics, clinical data, CMR data and peri-procedural complications were retrospectively retrieved. All procedures were guided by endo-cavitary EVM. According to non-invasive data collected before proceeding with EMB a suspected clinical diagnosis was expressed and compared to histological diagnosis
Results
One-hundred and sixty-two patients were included in the study. Mean age of the cohort resulted 40.9±14.7 years, with 26.5% of the included patients being females. ECG alterations were present in 51.3% of the population, with the most common abnormality being T wave inversion. Sustained or non-sustained ventricular tachycardia was registered in 51 (31.5%) of the patients, while 44 (27.2%) patients were referred for frequent isolated premature ventricular complex (PVC), and 19 (11.7%) after an episode of an arrhythmogenic syncope or resuscitated cardiac arrest. Suspected ARVC (41.6%) together with acute/chronic myocarditis (28.0%) were the main clinical diagnosis leading to an invasive approach. The sampling site was the right ventricle in 116 (72.5%), the left ventricle in 31 (19.4%), and both ventricles in 13 (8.1%) patients. Biopsy samplings were judged appropriate for histological analysis in 141 (87.0%) patients. Among the analyzed samples, a diagnosis was reached in 120 patients (74.1%). In the remaining 21 cases (25.9%), the analysis yielded nonspecific histologic findings, inconclusive results, or sampling error. The biopsy allowed to confirm the clinical diagnosis in 72 (60.0%) patients, while a different diagnosis was reached in 48 (39.0%) cases (Reclassification are showed Figure 1).In particular of 67 (41.6%) patients suspected for ARVC, only 32 (22.7) reached a confirmation. Conversely, the number of patients with acute/chronic myocarditis augmented from 45 (28.0%) to 47 (33.3%).
Conclusion
EMB guided by EVM reached a diagnostic yield as high as 74.1%. EMB proved to be a useful tool in the clinical management of patients, as it allowed to correctly reclassify a significant number of patients who would have been misdiagnosed based only on non-invasive assessment.

Abstract
Abstract
Background
The diagnosis of concealed cardiomyopathies in patients with ventricular arrhythmias (VAs) is one of the major challenging issues faced by physicians.
Purpose
We aimed at reporting the cardiomyopathic substrate in patients with recurrent arrhythmias of ventricular origin.
Methods
Consecutive patients with unexplained VAs underwent a complete diagnostic work-out, including endomyocardial biopsy (EMB).
Results
Ninety-seven patients were enrolled (76.3% male, age 39.7±13.3 yrs). The presenting arrhythmic manifestation was aborted cardiac arrest in 30 (30.9%) patients, sustained ventricular tachycardia (VT) in 9 (9.3%), nonsustained VT in 15 (15.5%) and frequent premature ventricular complexes in 43 (44.3%). Overall, 350 biopsies were collected (3.6/patient). The incidence of procedure-related complications was 5.1% (n=5): 4 major complications (1 rupture of a tricuspid chorda tendinea w/o hemodynamic impairment, 1 dissection of right external iliac artery treated with stent, 1 thrombotic occlusion of left superficial femoral artery which required surgical treatment, 1 TIA) and 1 minor complication (groin hematoma) occurred. The final diagnosis was arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) (n=41; 42.3%), followed by myocarditis (n=20; 20.6%), dilated cardiomyopathy (n=6; 6.2%), cardiac sarcoidosis (n=6; 6.2%), and myocarditis in ARVD/C (n=5; 5.1%). Among the 25 patients whose final diagnosis was consistent with myocarditis, an acute stage of the disease was documented in 7 (7.2%), while a chronic myocarditis in 18 (18.5%). Additionally, according to medical history and diagnostic workout, in 2 of the 6 patients the dilated cardiomyopathy had a likely post-inflammatory etiology. Absence of myocardial abnormalities was documented in 15 (15.5%) patients: this group included 1 case of methadone-induced torsade de pointes. The remaining 4 (4.1%) patients were diagnosed with a cardiac hypertrophy (n=2, 2.1%, secondary to exercise or Fabry disease), a dilated mitochondrial cardiomyopathy (n=1, 1.0%), a dilated cardiomyopathy in Emery-Dreifuss muscular dystrophy (n=1; 1.0%).
Conclusion
In our series, approximately 45% of patients with unexplained VAs had a final diagnosis of ARVD/C.

Abstract
Abstract
Introduction
Patients with myocarditis may fulfill the cardiac magnetic resonance (CMR) criteria set forth by the 2010 Task Force for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C), thereby increasing the risk of misdiagnosis.
Purpose
We sought to evaluate the role of CMR and endomyocardial biopsy (EMB) in the differential diagnosis between myocarditis and ARVD/C.
Methods
Consecutive patients presenting with ventricular arrhythmias, underwent a complete diagnostic work-out, which included CMR and EMB. The final diagnosis served as the gold standard to assess the diagnostic accuracy of CMR and EMB.
Results
Overall, 74 consecutive patients presenting with VAs underwent a complete diagnostic workout at our institution. The cohort was 70.3% male, with a mean age of 38.9±12.1 years. A final diagnosis of ARVD/C was made in 30 (40.5%) patients, whereas 19 (25.7%) had a diagnosis of myocarditis.
The McNemar's test showed significant differences in the diagnostic performance of EMB and cardiac MRI (p=0.003 for ARVD/C, p=0.04 for myocarditis).
At receiver operating characteristic (ROC) analyses, the area under the curve (AUC) to discriminate between controls and ARVD/C patients was 0.711 (95% CI: 0.59–0.83) for MRI and 0.944 (95% CI: 0.88–1.00) for biopsy (p<0.001). The AUC to discriminate between controls and patients with myocarditis was 0.656 (95% CI: 0.51–0.80) for MRI and 0.893 (95% CI: 0.80–0.99) for biopsy (p=0.006).
Diagnostic performance of CMR and EMB
Conclusion
Even though CMR has good diagnostic performances as single technique, a complete diagnostic work-out including EMB may frequently reduce the risk of misdiagnoses.

Abstract
Abstract
Background
Ventricular arrhythmias (VAs) are a frequent finding in agonist athletes (athl) at routine sport medicine visits. VAs impact on sport eligibility, their management, and the sudden arrhythmic death risk evaluation in athletes currently represents one of the greatest challenges across both the cardiology and sport medicine field.
Purpose
To describe how an advanced multi-methodical evaluation allowed diagnosis, risk stratification, targeted therapy and sport eligibility reassessment in a competitive athl cohort with ventricular arrhythmias and pathological findings at magnetic resonance (MR).
Methods
All consecutive competitive athl with denied sport eligibility due to ventricular arrhythmias that underwent an advanced invasive evaluation at our institute were enrolled.
A baseline and stress ECG, and late gadolinium enhanced evaluation (LGE) at MR were performed prior to invasive evaluation in all athl.
Invasive evaluation performed in all athl comprised of an electrophysiological study (EPS) to assess arrhythmic inducibility, an endo-cavitary electro-anatomical mapping (EAM), and a EAM and MR guided endo-myocardial biopsy (EMB). A defined diagnosis was postulated in all cases, specific therapeutic interventions were started and sport eligibility status reassessed after 6 months from discharge.
Results
Thirty-two competitive athl were enrolled in our study (32±6 y.o.; 77% male; 4±1 1h-training session/week); 26 (81%) athl practiced a mixed aerobic-anaerobic, 5 (16%) a pure-aerobic, while only 1 (3%) a pure anaerobic sport.
Arrhythmic presentation leading to sport eligibility revoke was: in 13 (40%) athl frequent (>2000/day) premature ventricular contractions (PVCs) at rest, in 2 (6%) PVCs during stress ECG, in 6 (18%) non-sustained ventricular tachycardia (VT), in 8 (25%) sustained VT, and in 3 (11%) ventricular fibrillation/cardiac arrest during sport practice.
MR alterations were described in all cases, and LGE at MR was found in 31 (87%) athl; a definite radiological diagnosis was obtained in 13 (40%) athl.
A normal myocardium at EMB was found only in 3 (8%) pts; in 15 (45%) a leukocyte infiltrate pattern compatible with myocarditis, in 11 (39%) fibro-fatty replacement, in 2 (5%) a mitochondrial disease and in 1 (3%) a sarcoidosis were proven, and diagnosis were consequently postulated.
EPS showed complex VAs inducibility in 8 (25%) cases, while a trans catheter ablation was performed in 10 (31%) athl. A total of 9 (28%) implantable cardioverter devices (ICDs) were implanted, for primary or secondary prevention.
According to invasive diagnostic findings and sport medicine guidelines, 8 (25%) athl had their sport eligibility statuts re-instated.
Conclusion
An invasive multi-methodical assessment allowed in all cases to reach a diagnosis and to start a targeted therapy in a cohort of competitive athl with VA and a pathological MR, granting in a significant (25%) percentage sport eligibility status re-instatement.
