Abstract

Resume Les pathologies de la voie droite sont historiquement les consequences de la chirurgie correctrice d’une malformation cardiaque congenitale en periode neonatale ou pediatrique (Tetralogie de Fallot, intervention de Ross). Ces chirurgies realisees dans l’enfance conduisent a l’apparition de dysfonctionnements de la voie droite (stenose, fuite) chez le grand enfant ou l’adulte jeune pour lesquels une nouvelle chirurgie serait a risque operatoire eleve. L’avenement des premieres valves percutanees en 2000 a permis d’ouvrir la voie de la revalvulation pulmonaire. La procedure de revalvulation pulmonaire percutanee offre une alternative credible a la chirurgie dans la population des patients porteurs d’une cardiopathie congenitale souvent multi operes donc a risque operatoire eleve. Les deux valves actuellement sur le marche francais (Melody®, SapienXT®) permettent de couvrir l’ensemble des indications exceptees les voies tres larges qui restent eminemment chirurgicales. Les equipes qui pratiquent ces actes sur des sujets jeunes doivent beneficier d’une experience suffisante pour limiter le risque procedural. Sur cette base, plusieurs equipes positionnent desormais la revalvulation pulmonaire percutanee en priorite sur la revalvulation chirurgicale qui n’est retenue qu’en cas d’impossibilite du traitement percutane.

Abstract

Funding Acknowledgements Type of funding sources: None. Background Lamin A/C cardiomyopathy (CM) is an inherited disease due to LMNA gene mutation with particular phenotype that associates conduction disorders, frequent atrial fibrillation and life-threatening ventricular arrhythmias, with normal or altered ventricular systolic function. Cardiac magnetic resonance (CMR) studies suggest frequent late gadolinium enhancement (LGE) involving septal mid-myocardium. Aims To assess the added value of CMR to conventional clinical features of Lamin A/C CM for the prediction of a positive LMNA gene testing. Methods We performed a retrospective monocentric study in all index patients referred for genetic testing for a clinical suspicion of Lamin A/C CM. Clinical, ECG and imaging data including CMR at time of genetic testing in patients with a positive test (LMNA+) and patients without (LMNA-) were compared. The diagnostic performances of relevant parameters for the prediction of a positive LMNA gene testing were analyzed in several logistic regression models. Results 90 patients were included (55 LMNA+, 35 LMNA-).49% had significant left ventricular (LV) dilatation on echocardiography,57% had a LV ejection fraction (LVEF) Conclusion CMR, particularly septal mid-myocardium LGE, carries good diagnostic accuracy to predict a positive LMNA gene testing in clinically suspected Lamin A/C CM with increased specificity when added to conventional red flags.

Abstract

Background Mitral valve prolapse (MVP) is a frequent pathology that can be complicated by mitral regurgitation, heart failure, rhythm disorders, arterial embolism and death. The aim of this study was to evaluate the prognostic interest of ventricular volumes, right ventricular ejection fraction (RVEF) and late gadolinium enhancement (LGE) assessed by cardiac magnetic resonance (CMR) imaging on cardiovascular morbi-mortality in a cohort of patients with MVP Methods We examined the prognostic value of CMR imaging in 237 patients with MVP (no to severe mitral regurgitation) included between 2010 and 2019. All patients underwent a comprehensive echocardiography. The main endpoint was a composite endpoint of cardiovascular death, heart failure, new onset atrial fibrillation, arterial embolism. Results Among the 237 patients (63% male), 97 (41%) had LGE (75 myocardial wall, 10 papillary muscle tip and 12 both locations). Factors associated with LGE in multivariable analysis were age (OR 1.02, P = 0.037), left ventricular (LV) mass (OR 1.01, P = 0.008) and pulmonary artery systolic pressure (PAPS, OR 1.02, P = 0.069). Follow-up was censored at the time of surgery or percutaneous repair. In univariate analysis NYHA class, LV mass, left atrial volume, PAPS, LV end-diastolic and end-systolic volumes, chordal rupture and MR degree were associated with outcome. RVEF and biventricular dysfunction (LV EF < 60% and RV EF < 40%) were also associated with impaired event-free survival (36.0 ± 17.0% vs 65.4± 5.8%, P = 0.019). Finally, LGE was associated with a decreased event-free survival (55.6 ± 9.9% vs 70.7± 6.9%, P = 0.002). In multivariablee analysis, moderate to severe mitral regurgitation (HR : 2.14 [1.44-3.19], P Conclusion CMR imaging provides additional prognostic information to echocardiography in the study of MVP. Myocardial fibrosis of the left ventricle and right ventricular function as assessed by CMR imaging are predictors of cardiovascular morbidity and mortality in MVP.

Abstract

Background The link between acute myocarditis (AM) and familial cardiomyopathy remains unclear. Purpose To assess the clinical significance of AM in families with cardiomyopathy. Methods and results We describe the pedigree of 6 families with at least one familial case of AM and a familial history of cardiomyopathy or sudden death (SD). AM was defined as an infarct-like clinical presentation with normal coronary arteries and myocardial inflammation (MI) documented by cardiac magnetic resonance (CMR), or as an autopsy proven AM. Detailed familial pedigrees are shown in the picture. In family 1 to 5, genetic testing was triggered by the association of a documented case of AM with an index case of cardiomyopathy or early SD. In this setting, all genetic testing revealed a mutation in the desmoplakin (DSP) gene. In family 1, patient II.1 (15 y.o) was diagnosed with AM, 6 months after his sister died suddenly at the age of 12. In family 2, patient II.4 (17 y.o) was diagnosed with AM. His mother had a DCM, with a CMR revealing the presence of MI. In family 3, patient IV.3 (22 y.o) died suddenly from an AM, attested by post-mortem autopsy. Her aunt had a DCM. In family 4, patient II.4 (41 y.o) had an AM, progressing toward a DCM. Her mother had died suddenly at the age of 39, and her niece had a DCM. In family 5, patient V.16 (9 y.o) presented 4 recurrent episodes of AM. Her cousin's mother had a DCM. In family 6, patient IV.3 had 3 episodes of AM, his father had previously been diagnosed with an arrythmogenic right ventricular cardiomyopathy (ARVC) with a desmoglein 2 (DSG2) mutation. Table shows detailed genotype-phenotype relationship in all mutation carriers screened in the 6 families. Phenotypes observed in mutation carriers Mutation DCM ARVC AM Isolated LGE (no cardiomyopathy, no AM) Family 1 (n=3) DSP 0 0 1 1 Family 2 (n=3) DSP 1 0 1 0 Family 3 (n=11) DSP 5 0 1 0 Family 4 (n=3) DSP 2 0 1 0 Family 5 (n=7) DSP 2 0 1 3 Family 6 (n=5) DSG2 0 1 1 1 Family Pedigrees Conclusion AM is strongly associated to desmosomal mutations when a familial history of cardiomyopathy is present, particularly in DSP gene. In these families, DCM phenotype and SD are frequent, and a notable proportion of isolated LGE suggestive of myocardial fibrosis is present in asymptomatic relatives. These results highlight the need for a comprehensive familial screening in case of AM.

Abstract

Background Structural valve degeneration (SVD) remains a major complication of aortic bioprostheses. Purpose We aimed to assess the mode of SVD leading to bioprosthetic aortic valve failure (BVF) in a large series of patients. Methods Between 2010 and 2017, we prospectively enrolled 261 consecutive patients with BVF related to SVD. All patients underwent a clinical work-up. Explanted bioprostheses were analysed for assessing the mechanism of SVD. Results The delay from surgery to SVD diagnosis was 8.5±3.3 (1.7 to 21.4) years, 10 years after exclusion of a specific type of bioprosthesis. Of the 261 SVD patients, 150 (57%) had mainly a stenotic type, and 111 (43%) a regurgitant type. In regurgitant SVD bioprosthesis was more frequently porcine (19 vs 7%, P=0.002), prosthesis diameter was larger (23.2±2.5 vs 21.6±1.9 mm; P Conclusion Structural valve degeneration remains a matter of concern in current practice with a mean delay of 8 to 10 years after surgery. Beside classical SVD with extensive calcification process other types of SVD can be observed with minimal calcification.

Abstract

Background Mitral valve prolapse (MVP) is a frequent disease that can be complicated by mitral regurgitation (MR), heart failure, arterial embolism, rhythm disorders and death. Left ventricular (LV) myocardial replacement fibrosis, a marker of maladaptive remodelling in numerous pathological conditions, has been evidenced in mitral valve prolapse (MVP) patients. Purpose To evaluate the prevalence, determinants, and prognostic significance of LV myocardial fibrosis assessed through late gadolinium enhancement (LGE+) by cardiac magnetic resonance (CMR) imaging in MVP patients. Methods We included 426 patients from 2 centres (55 ± 16 years, 56% male) with MVP (trace to severe MR) who underwent a comprehensive echocardiography and CMR imaging. Gadolinium was injected in 411 (96%) patients. The primary outcome endpoint was a composite of cardiovascular events. Results Of 411 patients, myocardial fibrosis (LGE+) was observed in 118 (29%; 100 myocardial wall including 66 basal inferolateral wall, 30 papillary muscle). LGE+ prevalence was 14% in trace-mild MR, 28% in moderate and 39% in severe MR, and was associated with worse heart chambers remodelling, larger mitral annulus, longer MV leaflets and presence of flail leaflet. Determinants of LGE+ in multivariable analysis were mainly LV mass (OR 1.01, P = 0.008) associated to the magnitude of MR and coronary artery disease. Four years cardiovascular events-free survival was decreased in patients with LGE+ (49.7 ± 11.9 vs. 76.2 ± 6.2%, P Fig. 1 ). Conclusions LV myocardial replacement fibrosis is frequent in MVP patients, related to both mitral valve apparatus alteration and MR grade (trace-mild 14%, moderate 28%, severe 39%), and emerges as a predictor of cardiovascular events. CMR imaging provides additional information to echocardiography in MVP.

Abstract

Renovascular hypertension accounts for 5-10 % of hypertensioncases in children; there is currently noconsensus on treatment. Here, we report on our clinical experience with this disease and outline the different pathways in which to investigate it. We report retrospectively on ten children diag- nosed with renovascular hypertension at the University Hos- pital of Nantes from 2001 to 2012. The main findings were obtained by fortuitous screening of children aged 2 months to 14 years old with neurofibromatosis (n=2) and fibromuscular dysplasia (n=8). The hypertension was always severe yet asymptomatic. Lesions were complicated in nine out of ten cases and included bilateral, multiple, mid-aortic syndrome and aneurysm. Doppler ultrasound associated with computed tomographyallowedfor aprecisediagnosisinsevenout often cases. Where ambiguities persisted, they were highlighted by arteriography, the gold standard investigation. Medical treatment was insufficient, leading to invasive procedures in nine out of ten children: 2 nephrectomies, 2 autotransplantations, and 21 repetitive percutaneous translu- minal angioplasties.After invasiveprocedures,blood pressure control improved in four cases and was resolved in three. Conclusion: Arteriography remains to be the gold standard technique for renovascular hypertension in children and can be combined with angioplasty when medical treat- ment is rendered obsolete. The role of computed tomog- raphy is controversial. Despite the heterogeneity of the children studied, we present a general medical and ther- apeutic management pathway for the treatment of this disease.

Abstract

Coronary CTA evaluation of the relationship between mitral valveannulus and coronary circulation : implications for percutaneous mitralannuloplasty Purpose To evaluate anatomical relationships between mitral annulus (MA), coronary arteries and coronary sinus (CS) in two groups of patients with and without moderate mitral insufficiency on coronary CTA to identify candidates to percutaneous mitral valve annuloplasty via the coronary sinus without risk of coronary artery occlusion. Materials and methods Fifty-one ECG-gated coronary CTA examinations, obtained during injection of iodinated contrast material on a 16 MDCT were retrospectively reviewed. The mitral valve annulus diameter, anatomical relationships between CS and coronary arteries and MA-CS distance were compared between both patient groups. Results The group with mitral insufficiency included16 patients and the control group included 35 patients. The AP diameter of the MA was 45,7±5,2 mm in the group with mitral insufficiency, significantly larger (p = 0.0009) compared to the control group (39,3±5,9 mm). In 70.4% of cases, the CS was located next to a coronary artery in an overlapping configuration. The unfavorable anatomical configuration with regards to annuloplasty appeared related to mitral insufficiency (p = 0.0539). The distance between MA and CS was greatly variable with the CS routinely extending over the left atrial surface : the distance was significantly (p = 0.0002) greater for all patients along the posterior surface (8,1±3,8 mm) compared to the lateral surface (5,2±4,6 mm) with this difference persisting within both groups : p = 0.004 for patients with mitral insufficiency and p = 0.0001 for control patients. Conclusion Our results demonstrate the value of coronary CTA in selecing candidates to percutaneous mitral annuloplasty. In 70.4% of cases, the CS overlaps a coronary artery with risk of compression at the time of annuloplasty.

Abstract

Resume Introduction nous rapportons quatre observations d’accident vasculaire cerebral ischemique revelant un anevrysme sacciforme. Patients et methodes : un homme et trois femmes (âges de 38 ans a 65 ans) ont ete admis a l’hopital pour un accident vasculaire cerebral ischemique. Le bilan neuroradiologique a mis en evidence un anevrysme intracrânien thrombose, pour trois des quatre cas, de taille inferieure a vingt cinq millimetres. Dans un cas, une ponction lombaire a ete realisee montrant une hemorragie sous arachnoidienne. Discussion nous discutons les hypotheses de la thrombose anevrysmale. Deux theories sont developpees pour l’expliquer : les theories « hemodynamique » et « parietale ». Nous proposons une conduite a tenir pour la prise en charge de ces anevrysmes atypiques, compte tenu du risque hemorragique potentiel. Conclusion l’histoire naturelle des anevrysmes intracrâniens n’est pas encore parfaitement comprise, mais leur thrombose peut etre a l’origine d’accident vasculaire ischemique.

Abstract

BACKGROUND AND PURPOSE: Patients harboring nongiant cerebral aneurysms may rarely present with an ischemic infarct distal to the aneurysm. The aim of this case series was to report clinical and radiologic characteristics of these patients, their management, and outcome. MATERIALS AND METHODS: We undertook a single-center retrospective analysis of consecutive patients admitted during an 8-year period with an acute ischemic stroke revealing an unruptured nongiant (
