RESUMO
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.
RESUMO
We present a case of a 42-year-old man with DiGeorge syndrome and congenital cardiac anomalies including a type B interrupted aortic arch who had previously undergone two bypasses between the ascending and descending thoracic aorta in childhood. He was found to have a 7.4-cm pseudoaneurysm of the descending thoracic aorta with the left subclavian artery arising from the aneurysm. The patient was treated with a single stage hybrid repair including left common carotid to subclavian bypass followed by thoracic endovascular aortic aneurysm repair.
RESUMO
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.

BACKGROUND: There are limited data about the clinical benefits of angiotensin receptor-neprilysin inhibitor (ARNI) in adults with congenital heart disease (CHD). The purpose of the study was to assess the clinical benefits (chamber function and heart failure indices) of ARNI in adults with CHD. METHOD: In this retrospective cohort study, we compared the temporal change in chamber function and heart failure indices between 35 patients that received ARNI for >6 months, and a propensity matched control group (n = 70) of patients that received angiotensin converting enzyme inhibitor or angiotensin-II receptor blocker (ACEI/ARB) within the same period. RESULTS: Of the 35 patients in the ARNI group, 21 (60%) had systemic left ventricle (LV) while 14 (40%) had systemic right ventricle (RV). Compared to the ACEI/ARB group, the ARNI group had greater relative improvement in LV global longitudinal strain (GLS) (28% versus 11% increase from baseline, p < 0.001) and RV-GLS (11% versus 4% increase from baseline, p < 0.001), and greater relative improvement in New York Heart Association functional class (-14 versus -2% change from baseline, p = 0.006) and N-terminal pro-brain natriuretic peptide levels (-29% versus -13% change from baseline, p < 0.001). These results were consistent across different systemic ventricular morphologies. CONCLUSIONS: ARNI was associated with improvement in biventricular systolic function, functional status, and neurohormonal activation, suggesting prognostic benefit. These results provide a foundation for a randomized clinical trial to empirically test the prognostic benefits of ARNI in adults with CHD, as the next step towards evidence-based recommendations for heart failure management in this population.

OBJECTIVES: Fontan-associated liver disease (FALD) is universal post-Fontan palliation; however, its impact on survival remains controversial and current diagnostic tools have limitations. We aimed to assess the prognostic role of liver fibrosis scores (aminotransferase to platelet ratio [APRI] and fibrosis-4 [FIB-4]) and their association with haemodynamics and other markers of liver disease. METHODS: 159 adults (age ≥18 years) post-Fontan undergoing catheterisation at Mayo Clinic, Minnesota, between 1999 and 2017 were included. Invasive haemodynamics and FALD-related laboratory, imaging and pathology data were documented. RESULTS: Mean age was 31.5±9.3 years, while median age at Fontan procedure was 7.5 years (4-14). Median APRI score (n=159) was 0.49 (0.33-0.61) and median FIB-4 score (n=94) was 1.12 (0.71-1.65). Correlations between APRI and FIB-4 scores and Fontan pressures (r=0.30, p=0.0002; r=0.34, p=0.0008, respectively) and pulmonary arterial wedge pressure (r=0.25, p=0.002; r=0.30, p=0.005, respectively) were weak. Median average hepatic stiffness by magnetic resonance elastography was 4.9 kPa (4.3-6.0; n=26) and 24 (77.4%) showed stage 3 or 4 liver fibrosis on biopsy; these variables were not associated with APRI/FIB-4 scores. On multivariable analyses, APRI and FIB-4 scores were independently associated with overall mortality (HR 1.31 [1.07-1.55] per unit increase, p=0.003; HR 2.15 [1.31-3.54] per unit increase, p=0.003, respectively). CONCLUSIONS: APRI and FIB-4 scores were associated with long-term all-cause mortality in Fontan patients independent of other prognostic markers. Correlations between haemodynamic status and liver scores were weak; furthermore, most markers of liver fibrosis failed to correlate with non-invasive indices, underscoring the complexity of FALD.

Background: Unrepaired truncus arteriosus (TA) carries poor prognosis due to complications of unrestricted pulmonary flow, truncal valve insufficiency, and pulmonary vascular disease. Currently, the hemodynamic profile of adults late after TA repair is unknown. We reviewed the hemodynamics, prevalence, and pathophysiology of pulmonary hypertension (PH) in this population. Methods: Eighteen adult patients with repaired TA who underwent cardiac catheterization at Mayo Clinic, MN, between 1997 and 2021 were identified.

RESUMO
Patients with pulmonary atresia and intact ventricular septum (PA-IVS) require intervention early in life, and most survive to a definitive procedure of either Fontan circulation or right ventricle to pulmonary artery (RV-PA) repair. It remains unknown how surgical strategy impacts hemodynamics and comorbidities in adults. Retrospective analysis of adults (age ≥18 years) with PA-IVS undergoing hemodynamic catheterization at Mayo Clinic, MN between January 2000 through January 2020 was performed. 14 patients in the RV-PA group (71% biventricular, 29% 1.5 ventricle repair) and 19 post-Fontan patients [9 lateral tunnel (48%), 6 atriopulmonary (32%), and 4 extracardiac (21%)] were identified. Median age was 29 (21, 34) years. There were no differences in demographics and laboratory data (including MELD-XI) between groups. All patients assessed for liver disease had evidence of hepatic congestion or cirrhosis (14 in the Fontan group and 4 in the RV-PA group). Invasive hemodynamics were comparable between groups with the Fontan and RV-PA groups having similar systemic venous pressure (15.7±4.4 vs. 14.3±6.2, pâ¯=â¯.44) and cardiac output (2.2±0.6 vs. 2.0±0.4 L/min/m2, pâ¯=â¯.23). There was no difference in transplant-free survival (pâ¯=â¯.92; 5-year transplant-free survival RV-PA 84%, Fontan 80%). Hemodynamic derangements, namely elevated systemic venous pressure and low cardiac output, are prevalent in patients with PA-IVS undergoing cardiac catheterization regardless of surgical strategy.

Background: Partial atrioventricular septal defects (pAVSDs) are mostly repaired in childhood; however, there are limited data describing these patients in adulthood. Objectives: The objective of this study was to describe clinical course and associations with outcomes in adults with repaired pAVSDs. Methods: A retrospective review of adults (≥18 years) with pAVSDs repaired in childhood who presented to the Adult Congenital Heart Disease Clinic at our institution was conducted. Results: Of 121 patients, the median age was 31 years (IQR: 22-43 years) and 71.9% were female. The median number of operations at the time of presentation was 1 (IQR: 1-2). Left atrioventricular valve (LAVV) replacement had been performed in 19.8% of patients. Among those with native LAVV, 41.2% had ≥ moderate regurgitation. Atrial arrhythmias were present in 34.7% and were associated with later age at repair (P = 0.02) and a high number of prior surgeries (P = 0.005). Estimated systolic pulmonary artery pressure >40 mmHg was seen in 19.8%. Over 4 (IQR: 1-12) years of follow-up, death occurred in 13 (10.7%) patients and reoperation was required in 39.7%. One-third had a LAVV prosthesis by the end of the study. Atrial fibrillation was independently associated with death or hospitalization on multivariable analysis. Conclusions: In this cohort of adults with pAVSDs repaired in childhood, atrial fibrillation was common at a young age and associated with worse outcomes. Thus, more studies are needed evaluating the cause of this arrhythmia burden and possible associated atrial myopathy. While many require surgery in adulthood, more information is needed regarding indications for and impacts of LAVV intervention as one-third had an LAVV prosthesis by the end of follow-up.
RESUMO
In patients with advanced heart failure (HF), temporary mechanical circulator support (TMCS) is used to improve hemodynamics, via left ventricular unloading, and end-organ function as a bridge to definitive therapy. While listed for cardiac transplantation, use of TMCS may be prolonged, preventing adequate mobility. Here, we describe the technique for placement of a percutaneous axillary intra-aortic balloon pump (IABP) using single-site arterial access to facilitate ambulation and subsequent safe removal without surgery or a closure device. Retrospective review of the experience with this approach at a single institution between September 2017 and February 2020 documented feasibility and safety. Baseline demographics, hemodynamic data, and clinical outcomes were collected. Thirty-eight patients had a total of 56 IABPs placed. There were no significant access site or cerebrovascular complications. One fifth of IABPs (21.4%) had balloon failure or migration, requiring placement of a new device, though no patients had significant complications from balloon failure. The majority (81.6%) of patients in the cohort on axillary IABP support were ambulatory and ultimately received the intended therapy (63.2% transplant, 13.2% durable left ventricular assist device, 5.3% other cardiac surgery). Percutaneous, axillary IABP is feasible and associated with an acceptable complication rate as a bridge to definitive therapy.

BACKGROUND: Heart failure with preserved ejection fraction is increasing in prevalence, but few effective treatments are available. Elevated left ventricular (LV) diastolic filling pressures represent a key therapeutic target. Pericardial restraint contributes to elevated LV end-diastolic pressure, and acute studies have shown that pericardiotomy attenuates the rise in LV end-diastolic pressure with volume loading. However, whether these acute effects are sustained chronically remains unknown. METHODS: Minimally invasive pericardiotomy was performed percutaneously using a novel device in a porcine model of heart failure with preserved ejection fraction. Hemodynamics were assessed at baseline and following volume loading with pericardium intact, acutely following pericardiotomy, and then again chronically after 4 weeks. Cardiac structure was assessed by magnetic resonance imaging. RESULTS: The increase in LV end-diastolic pressure with volume loading was mitigated by 41% (95% CI, 27%-45%, P<0.0001; ΔLV end-diastolic pressure reduced from +9±3 mm Hg to +5±3 mm Hg, P=0.0003, 95% CI, -2.2 to -5.5). The effect was sustained at 4 weeks (+5±2 mm Hg, P=0.28 versus acute). There was no statistically significant effect of pericardiotomy on ventricular remodeling compared with age-matched controls. None of the animals developed hemodynamic or pathological indicators of pericardial constriction or frank systolic dysfunction. CONCLUSIONS: The acute hemodynamic benefits of pericardiotomy are sustained for at least 4 weeks in a swine model of heart failure with preserved ejection fraction, without excessive chamber remodeling, pericarditis, or clinically significant systolic dysfunction. These data support trials evaluating minimally invasive pericardiotomy as a novel treatment for heart failure with preserved ejection fraction in humans.

BACKGROUND: Few contemporary studies have assessed the management and outcomes of patients with massive and submassive pulmonary embolism. Given advances in therapy, we report contemporary practice patterns and event rates among these patients. METHODS: We analyzed a prospective database of patients with massive and submassive pulmonary embolism. We report clinical characteristics, therapies, and outcomes stratified by pulmonary embolism type. Treatment escalation beyond systemic anticoagulation was defined as advanced therapy. Cox proportional hazards regression was used to identify predictors of 90-day mortality. RESULTS: Among 338 patients, 46 (13.6%) presented with massive and 292 (86.4%) with submassive pulmonary embolism. The average age was 63 ± 15 years, 49.9% were female, 32.0% had malignancy, and 21.9% had recent surgery. Massive pulmonary embolism patients received advanced therapy in 71.7% (30.4% systemic thrombolysis, 17.4% catheter-directed thrombolysis, 15.2% surgical embolectomy) and had greater 90-day mortality rates compared with submassive pulmonary embolism patients (41.3% vs 12.3%, respectively; P < .01). Most massive pulmonary embolism deaths (78.9%) occurred in-hospital, whereas mortality risk persisted after discharge for submassive pulmonary embolism. After multivariable adjustment, massive pulmonary embolism was associated with a 5.23-fold greater hazard of mortality (95% confidence interval, 2.70-10.13; P < .01). Advanced therapies among all pulmonary embolism patients were associated with a 61% reduction in mortality (95% confidence interval, 0.20-0.76; P < .01). CONCLUSIONS: Among contemporary massive and submassive pulmonary embolism patients, mortality remains substantial. Advanced therapies were frequently utilized and independently associated with lower mortality. Further investigation is needed to determine how to improve outcomes among these high-risk patients, including the optimal use of advanced therapies.

BACKGROUND: Critical limb ischemia (CLI) is a feared complication of peripheral vascular disease that often requires surgical management and may require amputation of the affected limb. We developed a decision model to inform clinical management for a 63-year-old woman with CLI and multiple medical comorbidities, including advanced heart failure and diabetes. METHODS: We developed a Markov decision model to evaluate 4 strategies: amputation, surgical bypass, endovascular therapy (e.g. stent or revascularization), and medical management. We measured the impact of parameter uncertainty using 1-way, 2-way, and multiway sensitivity analyses. RESULTS: In the base case, endovascular therapy yielded similar discounted quality-adjusted life months (26.50 QALMs) compared with surgical bypass (26.34 QALMs). Both endovascular and surgical therapies were superior to amputation (18.83 QALMs) and medical management (11.08 QALMs). This finding was robust to a wide range of periprocedural mortality weights and was most sensitive to long-term mortality associated with endovascular and surgical therapies. Utility weights were not stratified by patient comorbidities; nonetheless, our conclusion was robust to a range of utility weight values. CONCLUSIONS: For a patient with CLI, endovascular therapy and surgical bypass provided comparable clinical outcomes. However, this finding was sensitive to long-term mortality rates associated with each procedure. Both endovascular and surgical therapies were superior to amputation or medical management in a range of scenarios.
