Value of Longitudinal Strain to Identify Wild-Type Transthyretin Amyloidosis in Patients With Aortic Stenosis.

BACKGROUND: Wild-type transthyretin-related amyloidosis (ATTRwt) and degenerative aortic stenosis (AS) are both age-related. Diagnosis of cardiac amyloidosis (CA) among patients with AS may be difficult due to overlapping morphological and functional criteria. The aim of this study was to describe an echocardiographic longitudinal strain (LS) pattern among patients with AS with and without ATTRwt.Methods and Results:Patients who have AS with ATTRwt (n=30), AS without ATTRwt (n=50) and ATTRwt without AS (n=31) underwent two-dimensional speckle-tracking echocardiography. Transthyretin CA was based on positive bone scintigraphy without monoclonal gammopathy. All patients showed a gradual decrease in LS from the base to the apex resulting in a decrease of the global LS. A cut-off value of 1.0 for relative apical LS (average apical LS/[average basal LS+mid-LS]) was sensitive (88%) but less specific (68%) in differentiating ATTRwt among patients with severe AS. The best cut-off value for relative apical LS for identifying patients with ATTRwt among the whole population was 0.9 (sensitivity 74%, specificity 66%); however, 35%, 25% and 11% of patients who have ATTRwt without AS, with moderate AS and with severe AS, respectively, did not reach this threshold. CONCLUSIONS: A decrease of global and relative apical LS is common in patients with AS, even in the absence of ATTRwt. ATTRwt CA can be present even in the absence of relative apical sparing of LS.

A Prospective Study Identifying Predictive Factors of Cardiac Decompensation After Transjugular Intrahepatic Portosystemic Shunt: The Toulouse Algorithm.

BACKGROUND AND AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) is now a standard for the treatment of portal hypertension-related complications. After the TIPS procedure, incidence and risk factors of cardiac decompensation are poorly known. The main objectives were to measure the incidence of the onset of cardiac decompensation after TIPS and identify the predictive factors. APPROACH AND RESULTS: All patients with cirrhosis treated with TIPS between May 2011 and June 2016 were considered for inclusion. They received a cardiac assessment by standard biological parameters, transthoracic echocardiography, and right heart catheterization. Patients were followed for 1 year after TIPS insertion. The main endpoint was the incidence of cardiac decompensation requiring hospitalization. One hundred seventy-four patients were treated by TIPS during the period. One hundred patients who underwent a complete cardiac evaluation were included. A cardiac decompensation occurred in 20% of the patients. The parameters associated with the occurrence of severe cardiac decompensation were a prolonged QT interval corrected (462 vs. 443 ms; P = 0.05), an elevated pre-TIPS brain natriuretic peptide (BNP) or N-terminal pro-brain natriuretic peptide (NT-proBNP) level, an elevated E/A ratio (1.5 vs. 1.0; P = 0.001) and E/e' ratio (11 vs. 7; P < 0.001), and a left atrial dilatation (40 vs. 29 mL/m2 ; P = 0.011). The presence of aortic stenosis was also associated with cardiac decompensation. A level of BNP <40 pg/mL and NT-proBNP <125 pg/mL allowed identifying patients without risk of cardiac decompensation. Additionally, absence of diastolic dysfunction criteria at echocardiography ruled out the risk of further cardiac decompensation. CONCLUSIONS: Hospitalization for cardiac decompensation is observed in 20% of patients in the year after TIPS insertion. Combining BNP or NT-proBNP levels and echocardiographic parameters should help improve patient selection.

Myocardial multilayer strain does not provide additional value for detection of myocardial viability assessed by SPECT imaging over and beyond standard strain.

BACKGROUND: The aim of this study was to evaluate the value of multilayer strain analysis to the assessment of myocardial viability (MV) through the comparison of both speckle tracking echocardiography and single-photon emission computed tomography (SPECT) imaging. We also intended to determine which segmental longitudinal strain (LS) cutoff value would be optimal to discriminate viable myocardium. METHODS: We included 47 patients (average age: 61 ± 11 years) referred to our cardiac imaging center for MV evaluation. All patients underwent transthoracic echocardiography with measures of LS, SPECT, and coronary angiography. RESULTS: In all, 799 segments were analyzed. We correlated myocardial tracer uptake by SPECT with sub-endocardial, sub-epicardial, and mid-segmental LS values with r = .514 P < .0001, r = .501 P < .0001, and r = .520 P < .0001, respectively. The measurements of each layer strain (sub-endocardial, sub-epicardial, and mid) had the same performance to predict MV viability as defined by SPECT with areas under curve of 0.819 [0.778-0.861, P < .0001], 0.809 [0.764-0.854, P < .0001], and 0.817 [0.773-0.860, P < .0001], respectively. The receiver-operating characteristic analysis yielded a cutoff value of -6.5% for mid-segmental LS with a sensitivity of 76% and specificity of 76% to predict segmental MV as defined by SPECT. CONCLUSIONS: Multilayer strain analysis does not evaluate MV with more accuracy than standard segmental LS analysis.

Lack of Correlations between Electrophysiological and Anatomical-Mechanical Atrial Remodeling in Patients with Atrial Fibrillation.

BACKGROUND: Atrial fibrillation (AF) progressively leads to electrical remodeling (ER) and anatomical-mechanical remodeling (AR), whose relationships in humans remain poorly known. METHODS: ER and AR were compared in patients undergoing percutaneous radiofrequency (RF) ablation for AF. ER was defined by right and left appendage activation rates as a surrogate for atrial refractory periods. AR was approached by left atrial (LA) diameters and area and left atrial appendage (LAA) area and contractile function (mean emptying flow velocity) (LAAFV) before RF ablation. Mean duration between successive LAA contractions was considered as LAA mechanical rate. RESULTS: Forty-one patients (31 men, age: 64 ± 9 years) with paroxysmal (27%), persistent (61%), or long-persistent AF (12%) were prospectively included (ejection fraction: 44 ± 16%). Parameters exploring AR were highly correlated to each other: LA area (28 ± 7 cm(2) ), LAA area (5.7 ± 2.25 cm(2) ), LA transverse (49 ± 7 mm), and anteroposterior diameter (59 ± 13 mm) or LAAFV (29 ± 13 cm/s; P < 0.05 for each comparison). Parameters exploring ER were also highly correlated: right atrial appendage (RAA; 181 ± 39 ms) and LAA (176 ± 33 ms) activation rates (P < 0.0001). There was no significant correlation between any ER and AR parameter. Only LAA mechanical rate (174 ± 36 ms) was correlated to LAA or RAA activations rates (P ≤ 0.01). CONCLUSION: ER and AR are not mutually related, atrial activation rate being not correlated to LA or LAA size or function. Thus, the mechanisms leading to AF-induced atrial remodeling may differ for anatomical and electrophysiological aspects.

Prediction of all-cause mortality from gated-SPECT global myocardial wall thickening: comparison with ejection fraction and global longitudinal 2D-strain.

BACKGROUND: The aim of this study was to assess the correlation between global wall thickening (GWT) obtained by gated-single photon emission computed tomography (SPECT) and echocardiographic measures [ejection fraction (EF), global longitudinal strain (GLS), and strain rate (GLSR)] and to compare their prognostic value for all-cause mortality. METHODS AND RESULTS: Seventy-four patients with referral for dipyridamole myocardial perfusion SPECT were prospectively included and underwent transthoracic echocardiography to measure left ventricular EF, GLS, and GLSR. The strongest correlation with GWT was for EF (R = 0.63, P < .001), followed by GLSR (R = -0.57, P < .001) and GLS (R = -0.53, P < .001). There were ten deaths over a period of 14.6 ± 5.7 months. Using the multivariate Cox analysis, summed stress score (HR 1.108; P = .023), EF (HR 1.01, P = .031), GLS (HR 1.593, P = .001), and GWT (HR 0.898, P = .034) remained independent predictors of mortality. Mean survival rate evaluated by Kaplan-Meier analysis was longer in patients with GWT ≥ 24% (21.9 ± 0.6 months) than those with GWT < 24% (13.6 ± 2.7 months; P < .001). CONCLUSIONS: GWT assessed is a highly sensitive tool to detect early myocardial systolic dysfunction and may bring additional prognostic information.

New concept of myocardial longitudinal strain reserve assessed by a dipyridamole infusion using 2D-strain echocardiography: the impact of diabetes and age, and the prognostic value.

AIMS: Although dipyridamole is a widely used pharmacological stress agent, the direct effects on myocardium are not entirely known. Diabetic cardiomyopathy can be investigated by 2D-strain echocardiography. The aim of this study was to assess myocardial functional reserve after dipyridamole infusion using speckle-tracking echocardiography. METHODS: Seventy-five patients referred for dipyridamole stress myocardial perfusion gated SPECT (MPGS) were examined by echocardiography to assess a new concept of longitudinal strain reserve (LSR) and longitudinal strain rate reserve (LSRR) respectively defined by the differences of global longitudinal strain (GLS) and longitudinal strain rate between peak stress after dipyridamole and rest. Twelve patients with myocardial ischemia were excluded on the basis of MPGS as gold standard. RESULTS: Mean LSR was -2.28±2.19% and was more important in the 28 (44%) diabetic patients (-3.27±1.93%; p=0.001). After multivariate analyses, only diabetes improved LSR (p=0.011) after dipyridamole infusion and was not associated with glycaemic control (p=0.21), insulin therapy (p=0.46) or duration of the disease (p=0.80). Conversely, age (p=0.002) remained associated with a decrease in LSR. LSSR was also correlated to age (p=0.005). Patients with a LSR<0% have a better survival after 15 months (log-rank p=0.0012). CONCLUSION: LSR explored by 2D speckle-tracking echocardiography after dipyridamole infusion is a simple and new concept that provides new insights into the impact of diabetes and age on the myocardium with a potential prognostic value.

One train may hide another: anomalous origin of the left coronary artery from the pulmonary artery revealed by supraventricular tachycardia.

We report the case of a 1-month-old boy with an unusual association of supraventricular tachycardia and anomalous origin of the left coronary artery from the pulmonary artery. Although signs of infarction were visible on the first electrocardiogram, the presence of an arrhythmia did not immediately suggest a coronary anomaly. Echocardiography allowed the diagnosis, thus leading to appropriate care.

Early Detection of Localized Immunity in Experimental Autoimmune Myocarditis Using [99mTc]Fucoidan SPECT.

PURPOSE: The aim of the study was to evaluate the ability of technetium-99m-fucoidan ([99mTc]fucoidan), a molecular imaging agent specific for selectins, in the assessment of early localized immunity in a rat model of experimental autoimmune myocarditis (EAM). PROCEDURES: EAM was induced in Lewis rats and troponin T; brain natriuretic peptide (BNP) and anti-myosin antibodies were measured in plasma. Separately, [99mTc]fucoidan single-photon emission computed tomography (SPECT)/x-ray computed tomography (CT) was performed in the very early phase of myocarditis at 10, 15, and 21 days after immunization. Then, hearts were collected and used for autoradiography, well counting, histology, and flow cytometry analysis. RESULTS: The EAM acute phase is characterized by extensive myocardial necrosis, release of troponin and BNP, and pericardial effusion. [99mTc]Fucoidan uptake was significantly increased in EAM compared with controls starting from D15. There was a close relationship between uptake of the tracer and myocardial content in CD45+, CD8+, CD11b+, and CD31+ cells. CONCLUSIONS: [99mTc]Fucoidan SPECT/CT accurately diagnosed the autoimmune attack in the early steps of EAM and could be used to monitor disease evolution and therapy efficiency.

Effects of Spinal Anaesthesia on Left Ventricular Function: An Observational Study using Two-Dimensional Strain Echocardiography.

OBJECTIVE: Hypotension frequently occurs during spinal anaesthesia (SA), especially in the elderly. This side effect could have a cardiac component per se (myocardial contractility impairment). Two-dimensional (2D) strain and strain rate imaging are new echocardiographic methods allowing an accurate assessment of myocardial function by quantifying myocardial deformation. Allowing quantification of minor myocardial dysfunction not detectable by standard echocardiography, strain imaging could bring new perspective on the cardiac effect of SA. Our objective was to evaluate the effects of SA on left ventricular function assessed by 2D strain echocardiography. METHODS: In this prospective observational study, we enrolled 20 patients older than 60 years, who underwent elective lower-limb surgery under SA. Myocardial strain imaging were collected before and 20 minutes after SA (injection of 10 mg of isobaric bupivacaine with 5 µg of sufentanil). RESULTS: We observed an increase in global longitudinal reconnoitering (Δ-0.2±0.3% s-1; p<0.005), whereas left ventricular ejection fraction was not modified by SA. CONCLUSION: This slight increase in myocardial contractility could be an adaptive mechanism to compensate the preload decrease and limit the blood pressure drop.

Spleno-hepatic index to predict portal hypertension by equilibrium radionuclide ventriculography.

BACKGROUND: Structural and morphological changes accompanying liver cirrhosis lead to portal hypertension (PHT), which is the first step of most of the complications in patients with liver cirrhosis. Therefore, the development of noninvasive techniques to detect PHT is crucial for prognosis and treatment. AIM: The aim of our study was to assess the diagnostic performance of a new spleno-hepatic index (SHI) measured from equilibrium radionuclide ventriculography (ERV) images in detecting patients with cirrhotic PHT. METHODS AND RESULTS: A total of 38 patients with PHT were compared with 30 controls without liver disease. The SHI was measured on the sum of the tomographic images from the ERV and calculated according to the following formula: SHI=(mean splenic count×longest hepatic length)/mean hepatic count. Mean SHI was 54±14 and 36±8 (P<0.001) among patients with PHT and controls, respectively. A cutoff value of 40 for the SHI allowed a sensitivity of 90% and specificity of 77% to detect PHT. SHI greater than 51 was 100% specific. In a subset of 25 patients, SHI was not correlated with hepatic venous pressure gradient measured invasively in the right hepatic vein (R=-0.08, P=0.70). CONCLUSION: Quantification of SHI derived from ERV could be used to detect liver cirrhosis with PHT although it is not linearly correlated with the hepatic venous pressure gradient. SHI should be considered as a useful index for the identification of PHT in patients referred for the detection/exploration of cirrhotic cardiomyopathy by ERV.

Pilot study for left ventricular imaging phenotype of patients over 65 years old with heart failure and preserved ejection fraction: the high prevalence of amyloid cardiomyopathy.

This study sought to phenotype patients over 65 years old with heart failure and preserved ejection fraction (HFpEF) using clinical available comprehensive cardiovascular imaging modalities. Forty-nine patients with HFpEF and without coronary artery disease underwent clinical evaluation, electrocardiography, echocardiography, cardiac magnetic resonance (CMR) and 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid scintigraphy (99mTc-DPD). The mean population age was 76 ± 8 years. Most of the patients (53 %) were NYHA class II. Mean NT-Pro-NBNP level was 1961 ± 2372 pg/ml. CMR exhibited a hypertrophic cardiomyopathy or infiltrative pattern in 3 (6 %) and 15 (31 %) patients, respectively. In the latter subgroup, 99mTc-DPD was suggestive of transthyretin-related cardiac amyloidosis for nine (18 %) patients, while AL amyloidosis was proven in five patients (10 %) by extracardiac (n = 3, 6 %) or endomyocardial (n = 2, 4 %) biopsies-one patient declined tissue biopsy. Compared to patients with unspecified cardiomyopathy (n = 31), patients with amyloid cardiomyopathy (n = 15 or n = 14/proven) had less hypertension, lower systolic blood pressure and higher NT-pro BNP level. Their electrocardiogram showed lowest QRS voltage and longer QRS duration. Left ventricular (LV) pattern was characterized by a more pronounced LV hypertrophy, a smaller ejection fraction and a decrease of global longitudinal strain associated with an increase of longitudinal strain apical-to-basal ratio. In patients over 65 years, HFpEF is a heterogeneous syndrome with at least a 29 % prevalence of amyloid cardiomyopathy. Combined CMR and 99mTc-DPD are helpful imaging tools for accurate phenotyping of patients amenable to histopathological diagnosis or genetic testing, and should be considered for proper management of this population. Further longitudinal investigations are needed to better clarify these preliminary results.

Cardiovascular effects of low-dose spinal anaesthesia as a function of age: An observational study using echocardiography.

BACKGROUND: Spinal anaesthesia (SA) is a widely used technique of regional anaesthesia but hypotension is an adverse effect commonly observed, especially in elderly patients. OBJECTIVE: The objective of this study was to assess the cardiovascular effects induced by a single injection of a low-dose SA during elective surgery by using transthoracic echocardiography (TTE) and to compare these effects in patients older and younger than 70 years of age. DESIGN: Observational study. SETTING: Single centre university hospital. PATIENTS OR OTHER PARTICIPANTS: Forty-six patients scheduled for surgery under SA were included in the study (25 patients<70 years and 21 patients ≥ 70 years). INTERVENTION(S): A cardiologist, blinded to all clinical parameters, interpreted the TTE. MAIN OUTCOME MEASURES: Two TTEs were performed for each patient: one at baseline before and the second 20 minutes after the placement of the SA. RESULTS: Sixty-six percent of patients became hypotensive in the ≥ 70 years group whereas no episode of hypotension occurred in the<70 years group (P<0.0001). At baseline (i.e. prior to SA), when compared to younger patients, elderly patients had both a lower E/A ratio (0.8 [0.5-2.1] vs. 1.4 [0.7-1.6], P=0.001) as well as a lower LVEF (50.4% [37.7-72.3] vs. 60.9% [44.8-69.8], P<0.0001). SA in the elderly induced a larger decrease in the cardiac index (CI) (-0.5 L·min(-1)·m(-2) [-0.8 to -0.3] vs. -0.2 L·min(-1)·m(-2) [-0.8-0.1], P<0.0001), LV stroke volume (-8mL [-13-4] vs. -2mL [-14 to -1], P<0.0001) and systemic vascular resistances (SVR) (-2.2 WU [-6.7-0.3] vs. -0.8 WU [-2.3-0.1], P<0.0001). CONCLUSIONS: Hypotension is more frequent among elderly patients, even after low-dose SA. Known age-related changes in cardiovascular performance, such as impaired myocardial relaxation and decreased systolic function could be responsible for the decrease in cardiac output (CO) and SVR seen in these patients.

Assessment of valvular surfaces in children with a congenital bicuspid aortic valve: preliminary three-dimensional echocardiographic study.

BACKGROUND: Congenital bicuspid aortic valve (BAV) is the most common congenital heart defect and may be responsible for aortic stenosis early in life. However, its pathogenesis remains unclear. A relationship between the severity of aortic stenosis and valvular surfaces has not been reported in the paediatric population. AIMS: To assess the feasibility of three-dimensional transthoracic echocardiographic planimetry in congenital BAV in children and to evaluate the influence of valvular asymmetry and aortic valve area (AVA) on stenosis severity. METHODS: Seventy consecutive children with BAV were included in this prospective single-centre study. Using the multiplanar review mode, surfaces were measured by planimetry (in systole for AVA and diastole for cusp surfaces). The degree of stenosis was assessed by instantaneous aortic Doppler. Results are expressed as medians and first and third quartiles. RESULTS: Median age was 5.6 years (2.2-11.5). Feasibility was 97%. Intra- and interobserver concordances were excellent for the measurement of cusp surfaces and AVA. Among the 70 children, 25 had aortic stenosis. The small/large cusp ratio was strongly associated with aortic stenosis (P<0.001). The area under the receiver operating characteristic curve was 0.89 (95% confidence interval 0.82-0.97). The best cut-off value for differentiating stenotic from non-stenotic valve was 0.75, with 84% sensitivity and 83% specificity. When indexed for body surface area, AVA was significantly smaller (P=0.031) in case of stenotic BAV (1.51cm(2) [0.99-2.28]) compared with non-stenotic BAV (1.99cm(2) [1.57-2.52]). CONCLUSIONS: Three-dimensional echocardiographic planimetry is a feasible and reproducible method for assessing aortic surfaces in congenital BAV. Aortic stenosis seems to strongly depend on the asymmetry of the valve.

Relationship between left ventricular sphericity and trabeculation indexes in patients with dilated cardiomyopathy: a cardiac magnetic resonance study.

AIMS: To study the relationship between left ventricular (LV) trabeculations, volume, and sphericity in patients with dilated cardiomyopathy (DCM) by cardiac magnetic resonance imaging (CMR). METHODS AND RESULTS: Eighty-two patients with DCM were prospectively explored by CMR. The segmental trabeculation index (STI) was defined by the ratio of trabeculated layer thickness on compacted layer thickness per segment. The global trabeculation index (GTI) was defined by the ratio of the sum of the total trabeculated layer thickness to the sum of the total compacted layer thickness. The apex was excluded from the analysis. The mean number of segments with trabeculation per patient was 10 ± 2 with a mean GTI of 0.68 ± 0.32. The LV sphericity index was inversely correlated with LV ejection fraction (R = -0.42, P = 0.0002) and positively with the brain natriuretic peptide (BNP) level (R = 0.34, P = 0.003). The maximal STI was positively correlated with the indexed LV end-diastolic volume (R = 0.32, P = 0.004) and the LV sphericity index (R = 0.25, P = 0.02), but not with the BNP level or LV ejection fraction. The GTI was positively correlated with the LV sphericity index (R = 0.27, P = 0.016) but not with indexed LV end-diastolic volume, BNP levels, or LV ejection fraction. CONCLUSION: Trabeculation indexes depend on LV shape and are positively correlated with LV sphericity. These results encourage interpreting LV trabeculation with caution in patients with DCM, considering additional morphologic criteria such as LV geometry.

Relation between left ventricular outflow tract obstruction and left ventricular shape in patients with hypertrophic cardiomyopathy: a cardiac magnetic resonance imaging study.

BACKGROUND: Hypertrophic cardiomyopathies (HCM) are often associated with left ventricular (LV) outflow tract obstruction, which can explain symptoms and impact prognosis. AIMS: To better understand the mechanisms that link obstruction and LV shape in HCM. METHODS: Patients with HCM who underwent cardiac magnetic resonance (CMR) imaging were included retrospectively. Obstructive HCM was defined as LV outflow gradient more than 30 mm Hg at rest by transthoracic echocardiography. The LV shape and mitral angle were assessed by CMR. Results were compared with control subjects. RESULTS: Mean LV-mitral angle was smaller in patients with obstructive HCM (n=29) than in patients with non-obstructive HCM (n=15) or control subjects (n=15) (80 ± 5° vs 87 ± 7° [P=0.0002] and 89 ± 2° [P<0.0001]). Mean mitral papillary muscles angle was greater in patients with non-obstructive HCM than in patients with obstructive HCM or control subjects (136 ± 17° vs 123 ± 16° [P=0.007] and 118 ± 10° [P=0.002]). Patients with non-obstructive HCM had a greater mean LV-aortic root angle than patients with obstructive HCM or control subjects (139 ± 6° vs 135 ± 7° [P=0.04] and 133 ± 7° [P=0.03]). CONCLUSION: There is a relation between morphological and functional parameters in HCM within which the mitral valve is probably part of pathophysiogenesis.

Prognostic value of right ventricular two-dimensional global strain in patients referred for cardiac surgery.

BACKGROUND: Right ventricular (RV) function is a strong predictor of patient outcome after cardiac surgery. Limited studies have compared the predictive value of RV global longitudinal strain (RV-GLS) with tricuspid annular plane systolic excursion (TAPSE) and RV fractional area change (RVFAC) in this setting. METHODS: The study included 250 patients (66 ± 13 years old, LVEF = 52% ± 12%) referred for cardiac surgery (EuroSCORE-II = 4.8% ± 8.0%). RV function before surgery was assessed by RV-GLS by using speckle-tracking analysis (3-segment from the RV free wall), RVFAC and TAPSE was compared with postoperative outcome defined by 1-month mortality. RESULTS: Overall, 19 patients (7.6%) had RVFAC < 35%, 34 (13.6%) had TAPSE < 16 mm, and 99 (39.6%) had impaired RV-GLS > -21% (35% with normal RVFAC ≥ 35%). Postoperative death (n = 25) was higher in patients with abnormal RV-GLS > -21% (22% vs 3%; P < .0001), TAPSE < 16 mm (24% vs 8%; P = .007), and RVFAC < 35% (32% vs 9%; P = .001). Mortality was 3% in patients with preserved RV-GLS. In patients with preserved RVFAC ≥ 35% but abnormal RV-GLS, mortality was similar to that of those with RVFAC < 35% (20% vs 32%; P = .12). Among RV systolic indexes, only RV-GLS was associated with patient outcome by multivariate analysis adjusted to EuroSCORE-II and cardiopulmonary bypass duration. CONCLUSIONS: RV-GLS is a sensitive marker of RV dysfunction and correlates with postoperative mortality.

A family history of dilated cardiomyopathy induced by viral myocarditis.

Myocarditis can lead to acute heart failure, cardiogenic shock, or sudden death and later, dilated cardiomyopathy (DCM) with chronic heart failure. We report the cases of two DCM induced by acute and past myocarditis in the same family and expressed by its two main complications within few weeks: an hemodynamic presentation as a fulminant myocarditis rapidly leading to cardiac tranplantation and a rythmologic presentation as an electrical storm leading to catheter ablation of ventricular tachycardia. These cases ask the question of the family predisposition to viral myocarditis leading to DCM.
