RESUMEN
BACKGROUND: There are limited data about the impact of timing of pulmonary valve replacement (PVR) on right heart reverse remodeling in patients with pulmonary regurgitation following intervention for isolated pulmonary valve stenosis (PS). This study compared differences in postprocedural right heart reverse remodeling after early versus late PVR (defined as PVR before versus after attainment of the conservative consensus criteria proposed by Bokma et al, 2018) in patients with prior intervention for PS, using patients with tetralogy of Fallot as the reference group. METHOD AND RESULTS: Right atrial reservoir strain and right ventricular free wall strain was measured at baseline, 1 and 3 years after PVR. There were 114 patients with PS (early PVR, 87 [76%]; late PVR, 27 [24%]) and 291 patients with tetralogy of Fallot (early PVR, 197 [67%]; late PVR, 96 [33%]). The PS group had greater improvement in right atrial reservoir strain at 1 year (12%±4% versus 8%±4%; P<0.001) and 3 years (15%±6% versus 9%±6%; P<0.001), and a greater improvement in right ventricular free wall strain at 1 year (12%±4% versus 7%±3%, P=0.008) and 3-years (16%±6% versus 12%±5%; P=0.01) after PVR compared with the tetralogy of Fallot group. There was no difference in right heart reverse remodeling between patients who underwent early versus later PVR within the PS group. In contrast, late PVR was associated with less right heart reverse remodeling within the tetralogy of Fallot group. CONCLUSIONS: These data suggest that patients with palliated PS presenting pulmonary regurgitation have a more benign clinical course, and hence delaying PVR in this population may be appropriate.

Background: The purpose of this study was to define the risk and outcomes of esophageal varices in adults with Fontan palliation and liver cirrhosis undergoing esophagogastroduodenoscopy (EGD). Method: The results of EGD, abdominal ultrasound, and liver biopsy, as well as clinic notes from the hepatologist, were reviewed to determine the diagnosis of cirrhosis and esophageal varices. The incidence of acute gastrointestinal bleeding complication was assessed among patients with esophageal varices using the time of EGD as the baseline. Results: Of 149 patients with Fontan palliation and liver cirrhosis, the prevalence of esophageal varices at baseline EGD was 34% (51 of 149). Of 98 patients without esophageal varices at baseline EGD, 27 (27%) underwent subsequent EGD, of whom 11 showed a new diagnosis of esophageal varices. The incidence of a new diagnosis of esophageal varices was 9% per year. Of 62 patients with esophageal varices, 9 (15%) had acute gastrointestinal bleeding complications during 45 (37-62) months of follow-up, yielding an incidence of 5% per year. Of the 9 patients, 8 underwent EGD and variceal banding during the hospitalization for bleeding and 1 patient died of septicaemia. Of the 8 patients who survived to hospital discharge, 2 patients were readmitted for esophageal bleeding within 12 months from the index hospitalization. Higher hepatic vein wedge pressure and hepatic vein pressure gradient were associated with esophageal varices and bleeding complications. Conclusions: In this selected sample of adults with Fontan palliation and liver cirrhosis, esophageal varices were relatively common, and patients with esophageal varices had risk of bleeding complications.
Contexte: Cette étude visait à déterminer le risque de varices Åsophagiennes et leur issue clinique chez les adultes ayant fait l'objet d'une intervention de Fontan et présentant une cirrhose hépatique chez qui une Åsophagogastroduodénoscopie (OGD) a été réalisée. Méthodologie: Les résultats de l'OGD, de l'échographie abdominale et de la biopsie du foie, ainsi que les notes cliniques de l'hépatologue ont été consultés pour établir les diagnostics de cirrhose et de varices Åsophagiennes. L'incidence des complications hémorragiques gastro-intestinales aiguës a été évaluée chez les patients présentant des varices Åsophagiennes en utilisant l'OGD initiale comme référence de départ. Résultats: Chez les 149 patients ayant fait l'objet d'une intervention de Fontan et présentant une cirrhose hépatique, la prévalence des varices Åsophagiennes lors de l'OGD initiale était de 34 % (51/149). Parmi les 98 patients sans varices Åsophagiennes lors de l'OGD initiale, 27 (27 %) ont subi une OGD ultérieure, et 11 d'entre eux ont alors reçu un diagnostic de varices Åsophagiennes. Le taux d'incidence des nouveaux diagnostics de varices Åsophagiennes était de 9 % par année. Sur les 62 patients présentant des varices Åsophagiennes, 9 (15 %) ont subi des complications hémorragiques gastro-intestinales aiguës au cours d'une période de suivi de 45 (37 à 62) mois, ce qui correspond à un taux d'incidence de 5 % par année. Huit des 9 patients ont subi une OGD et une ligature des varices par bande élastique durant leur hospitalisation en raison des complications hémorragiques, et un patient est décédé des suites d'une septicémie. Deux des 8 patients en vie au moment du congé de l'hôpital ont été réhospitalisés pour une hémorragie de l'Åsophage dans les 12 mois suivant la première hospitalisation. Une pression d'occlusion plus élevée de la veine hépatique ainsi qu'un plus grand gradient de pression de la veine hépatique ont été associés à la survenue de varices Åsophagiennes et de complications hémorragiques. Conclusions: Dans cet échantillon d'adultes ayant fait l'objet d'une intervention de Fontan et présentant une cirrhose hépatique, la fréquence des varices Åsophagiennes était relativement élevée, et les patients présentant des varices Åsophagiennes étaient exposés à un risque de complications hémorragiques.
RESUMEN
AIMS: Women with congenital heart disease (CHD) are at risk of pregnancy-related adverse outcomes (PRAO). The purpose of this study was to assess temporal changes in cardiac structure and function (cardiac remodelling) during pregnancy, and the association with PRAO in women with CHD. METHODS AND RESULTS: Retrospective study of pregnant women with CHD and serial echocardiograms (2003-2021). Cardiac structure and function were assessed at pre-specified time points: prepregnancy, early pregnancy, late pregnancy, and postnatal period. PRAO was defined as the composite of maternal cardiovascular, obstetric, and neonatal complications. The study comprised 81 women with CHD (age, 29 ± 5 years). Compared to the baseline echocardiogram, there was a relative increase in right ventricular systolic pressure (RVSP) (relative change 13 ± 5%, P < 0.001, in early pregnancy; and 18 ± 5%, P < 0.001, in late pregnancy). There was a relative decrease in right ventricle free wall strain (RVFWS) (relative change -11 ± 3%, P < 0.001, in late pregnancy; and -11 ± 4%, P = 0.003, in postnatal period), and a relative decrease in RVFWS/RVSP (relative change, -10 ± 5%, P = 0.02 in early pregnancy, -26 ± 7%, P < 0.001, in late pregnancy, and -14 ± 5%, P < 0.001, in postnatal period). Baseline right ventricular to pulmonary arterial (RV-PA) coupling, and temporal change in RV-PA coupling were associated with PRAO, after adjustment for maternal age and severity of cardiovascular disease. CONCLUSION: Women with CHD had a temporal decrease in RV systolic function and RV-PA coupling, and these changes were associated with PRAO. Further studies are required to delineate the aetiology of deterioration in RV-PA coupling during pregnancy, and the long-term implications of right heart dysfunction observed in the postnatal period.
RESUMEN
Background: Data are limited about the effect (or lack thereof) of sex on clinical outcomes in adults with coarctation of the aorta (COA). The purpose of this study was to compare atherosclerotic cardiovascular disease (ASCVD) risk profile, blood pressure (BP) data, echocardiographic indices, and mortality between men and women with COA. Methods: Retrospective study of adults with COA, and no associated left-sided obstructive lesions, who received care at Mayo Clinic (2003-2022). ASCVD risk profile was assessed as the prevalence of hypertension, hyperlipidemia, type 2 diabetes, obesity, smoking history, and coronary artery disease. A 24-hour BP monitor was used to assess daytime and nighttime BP and calculate nocturnal dipping. Results: Of 621 patients with isolated COA, 375 (60%) were men, and 246 (40%) were women. Women had similar ASCVD risk profile and daytime BP as men. However, women had less nocturnal dipping (7 ± 5 mm Hg vs 16 ± 7 mm Hg, P < 0.001), higher pulmonary artery mean pressure (23 mm Hg [interquartile range: 16-31] vs 20 mm Hg [interquartile range: 15-28], P = 0.04), and higher pulmonary vascular resistance index (3.41 ± 1.14 WU · m2 vs 3.02 ± 0.76 WU · m2, P = 0.006). Female sex was associated with all-cause mortality (adjusted hazard ratio 1.26, 95% confidence interval 1.04-1.94) and cardiovascular mortality (adjusted hazard ratio 1.38, 95% confidence interval 1.09-2.18). Conclusions: Women had a higher risk of both cardiovascular mortality and all-cause mortality compared to the risks in men. This difference may be related to the higher-than-expected ASCVD risk factors, abnormal nocturnal blood pressure, and pulmonary hypertension observed in women in this cohort. Further studies are required to identify optimal measures to address these risk factors.
Contexte: Il existe peu de données sur l'issue clinique en fonction du sexe chez les adultes présentant une coarctation de l'aorte (CoA). Le but de cette étude consistait donc à comparer le profil de risque de maladie cardiovasculaire athéroscléreuse (MCVAS), les données relatives à la pression artérielle (PA), les indices échocardiographiques et le taux de mortalité chez des hommes et des femmes présentant une CoA. Méthodologie: Il s'agissait d'une étude rétrospective réalisée chez des adultes présentant une CoA en l'absence de lésions obstructives gauches, soignés à la clinique Mayo entre 2003 et 2022. Le profil de risque de MCVAS a été évalué en fonction de la prévalence de l'hypertension, de l'hyperlipidémie, du diabète de type 2, de l'obésité, des antécédents tabagiques et de la coronaropathie. Une surveillance sur 24 heures a été utilisée pour évaluer la PA diurne et nocturne, en plus de calculer la chute nocturne de la PA. Résultats: Parmi les 621 patients présentant une CoA isolée, 375 (60 %) étaient des hommes et 246 (40 %) étaient des femmes. Les femmes présentaient une PA diurne et un profil de risque de MCVAS semblables aux hommes. Elles présentaient néanmoins une chute nocturne de la PA moins prononcée (7 ± 5 mmHg vs 16 ± 7 mmHg, p < 0,001), une pression artérielle pulmonaire moyenne plus haute (23 mmHg [max.-min. : 16-31] vs 20 mmHg [max.-min. : 15-28], p = 0,04) et un indice de résistance vasculaire pulmonaire plus élevé (3,41 ± 1,14 UW · m2 vs 3,02 ± 0,76 UW · m2, p = 0,006). Le sexe féminin a été associé à un plus fort taux de mortalité toutes causes confondues (rapport de risques ajusté : 1,26; intervalle de confiance à 95 % : 1,04-1,94) et de mortalité cardiovasculaire (rapport de risques ajusté : 1,38; intervalle de confiance à 95 % : 1,09-2,18). Conclusions: Les femmes sont exposées à un risque de mortalité cardiovasculaire et de mortalité toutes causes confondues plus élevé que les hommes. Cette différence pourrait être attribuable au rôle plus important que prévu joué par les facteurs de risque de MCVAS ainsi qu'à la pression artérielle nocturne anormale et à l'hypertension pulmonaire chez les femmes de cette cohorte. D'autres études sont nécessaires pour savoir quels seraient les paramètres optimaux qui permettraient d'évaluer ces facteurs de risque.
RESUMEN
Anticoagulant therapy is a mainstay in the management of patients with cardiovascular disease. The use of conventional anticoagulants carries potential side effects, mainly bleeding. Drugs targeting Factor XI (FXI) have been investigated in randomized controlled trials as a new option with more favorable outcomes. A comprehensive literature search was conducted to identify relevant studies comparing FXI inhibitors to placebo or standard therapy. The primary outcomes were incidence of all bleeding events, major bleeding, and thromboembolism. Secondary outcomes included incidence of all adverse events (AE), serious AE, and all-cause mortality. A total of 11 studies involving 10,536 patients were included. FXI inhibitors were associated with a trend toward reduction of bleeding events and incidence of thromboembolism compared to the control group (placebo/standard therapy). There was no statistically significant difference between both groups in terms of adverse events and all-cause mortality. When compared to enoxaparin, FXI inhibitors significantly reduced the risk of bleeding events (RR = 0.42, 95% CI: 0.23-0.76, P = 0.004) and thromboembolism (RR = 0.59, 95% CI: 0.44-0.77, P = 0.001). On the other hand, when compared to DOACs, FXI inhibitors were associated with a significant reduction in bleeding events but not thromboembolism. Whereas, compared to placebo, FXI inhibitors did not increase the risk of bleeding events, adverse events, or all-cause mortality (P > 0.05). FXI inhibitors could be a safer and more potent option for prevention of thromboembolism than conventional therapy.

BACKGROUND: Aortic aneurysm is common in patients with coarctation of aorta (COA), but it is unclear whether the risk of aortic aneurysms is due to COA or related to the presence of other risk factors such as bicuspid aortic valve (BAV) and hypertension. OBJECTIVES: The purpose of this study was to assess the relationship among COA, BAV, and thoracic aortic aneurysms. METHODS: A total of 867 patients with COA (COA group) were matched 1:1:1 to 867 patients with isolated BAV (BAV group) and 867 patients without structural heart disease (SHD) (no-SHD group). The COA group was further subdivided into a COA+BAV subgroup (n = 304 [35%]), and COA with tricuspid aortic valve (TAV) (COA+TAV subgroup [n = 563 (65%)]). Aortic dimensions were assessed at baseline and at 3, 5, and 7 years. RESULTS: Compared with the no-SHD group, the COA+BAV subgroup had larger aortic root diameter (37 mm [Q1-Q3: 30-43 mm] vs 32 mm [Q1-Q3: 27-35 mm]; P < 0.001) and mid ascending aorta dimeter (34 mm [Q1-Q3: 29-40 mm] vs 28 mm [Q1-Q3: 24-31 mm]; P = 0.008). Similarly, the BAV group had larger aortic root diameter (37 mm [Q1-Q3: 30-42 mm] vs 32 mm [Q1-Q3: 27-35 mm]; P < 0.001), and mid ascending aorta dimeter (35 mm [Q1-Q3: 30-40 mm] vs 28 mm [Q1-Q3: 24-31 mm]; P < 0.001). Compared with the COA+TAV subgroup, the COA+BAV subgroup and BAV group were associated with larger aortic root and mid ascending aorta diameter at baseline and follow-up. The risk of acute aortic complications was low in all groups. CONCLUSIONS: These findings suggest that BAV (and not COA) was associated with ascending thoracic aorta dimensions, and that patients with COA+TAV were not at a greater risk of developing ascending aortic aneurysms as compared with patients without SHD.

BACKGROUND: Adults with repaired tetralogy of Fallot (TOF) have right atrial (RA) remodeling and dysfunction, and RA function can be measured using speckle tracking echocardiography. There are limited data about the role of RA strain imaging for risk stratification in this population. We hypothesized that RA reservoir strain can identify TOF patients at risk of developing atrial arrhythmia. To test this hypothesis, we assessed the relationship between RA reservoir strain and atrial arrhythmias in adults with repaired TOF. METHOD: Retrospective cohort study of adults with repaired TOF, and no prior history of atrial arrhythmias. Atrial arrhythmia was defined as atrial fibrillation, atrial flutter/atrial tachycardia, and categorized as new-onset versus recurrent atrial arrhythmias. RESULTS: We identified 426 patients (age 33 ± 12 years; males 208 (49%)) that met the inclusion criteria. The mean RA reservoir strain, conduit strain, and booster strain were 34 ± 11%, 20 ± 9%, and 15 ± 12%, respectively. Of 426 patients, 73 (17%) developed new-onset atrial arrhythmias (atrial flutter/tachycardia n = 42; atrial fibrillation n = 31); annual incidence 1.9%. RA reservoir strain was associated with new-onset atrial arrhythmias (adjusted HR 0.95, 95% CI 0.93-0.97) after multivariable adjustment. Of 73 patients with new-onset atrial arrhythmia, 41 (56%) had recurrent atrial arrhythmia (atrial flutter/tachycardia n = 18; atrial fibrillation n = 23); annual incidence 11.2%. Similarly, RA reservoir strain was associated with recurrent atrial arrhythmias (adjusted HR 0.92, 95% CI 0.88-0.96) after multivariable adjustment. CONCLUSIONS: RA strain indices can identify patients at risk for atrial arrhythmias, and this can in turn, be used to guide the type/intensity of therapy in such patients.
