Adult congenital heart disease care in a municipal public health system.

Specialty care is associated with improved outcomes for adults with adult CHD and must be extended to the underserved. A retrospective cohort study was performed to describe the provision of care to adult CHD patients in America's largest municipal public health system including patient demographics, diagnostic and therapeutic procedures, and adherence to guideline-recommended surveillance. We identified 229 adult CHD patients aged >18 years through electronic medical records. The most common diagnoses were atrial septal defect, ventricular septal defect, patent ductus arteriosus, and valvular pulmonary stenosis. In total, 65% had moderate or greater anatomic complexity. A large number of patients were uninsured (45%), non-white (96%), and non-English speaking (44%). One hundred forty-six patients (64%) presented with unrepaired primary defects. Fifty eight patients underwent primary repair during the study period; 48 of those repairs were surgical and 10 were transcatheter. Collaboration with an affiliated Comprehensive Care Center was utilised for 28% of patients. A high proportion of patients received adult CHD speciality visits (78%), echocardiograms (66%), and electrocardiograms (56%) at the guideline-recommended frequency throughout the study period. There was no significant difference in the rate of adherence to guideline-recommended surveillance based on insurance status, race/ethnicity, or primary language status. The proportion of patients who had guideline-recommended adult CHD visits, echocardiograms, and electrocardiograms was significantly lower for those with more advanced physiological stages. These results can inform the provision of adult CHD care in other public health system settings.

Reproductive Health in Congenital Heart Disease: Preconception, Pregnancy, and Postpartum.

The prevalence of congenital heart disease (CHD) in pregnancy is rising due to the improved survival of patients with CHD into childbearing age. The profound physiological changes that occur during pregnancy may worsen or unmask CHD, affecting both mother and fetus. Successful management of CHD during pregnancy requires knowledge of both the physiological changes of pregnancy and the potential complications of congenital heart lesions. Care of the CHD patient should be based on a multidisciplinary team approach beginning with preconception counseling and continuing into conception, pregnancy, and postpartum periods. This review summarizes the published data, available guidelines and recommendations for the care of CHD during pregnancy.

COVID-19-Related Thrombotic and Bleeding Events in Adults With Congenital Heart Disease.

Background: Altered coagulation is a striking feature of COVID-19. Adult patients with congenital heart disease (ACHD) are prone to thromboembolic (TE) and bleeding complications. Objectives: The purpose of this study was to investigate the prevalence and risk factors for COVID-19 TE/bleeding complications in ACHD patients. Methods: COVID-19-positive ACHD patients were included between May 2020 and November 2021. TE events included ischemic cerebrovascular accident, systemic and pulmonary embolism, deep venous thrombosis, myocardial infarction, and intracardiac thrombosis. Major bleeding included cases with hemoglobin drop >2 g/dl, involvement of critical sites, or fatal bleeding. Severe infection was defined as need for intensive care unit, endotracheal intubation, renal replacement therapy, extracorporeal membrane oxygenation, or death. Patients with TE/bleeding were compared to those without events. Factors associated with TE/bleeding were determined using logistic regression. Results: Of 1,988 patients (age 32 [IQR: 25-42] years, 47% male, 59 ACHD centers), 30 (1.5%) had significant TE/bleeding: 12 TE events, 12 major bleeds, and 6 with both TE and bleeding. Patients with TE/bleeding had higher in-hospital mortality compared to the remainder cohort (33% vs 1.7%; P < 0.0001) and were in more advanced physiological stage (P = 0.032) and NYHA functional class (P = 0.01), had lower baseline oxygen saturation (P = 0.0001), and more frequently had a history of atrial arrhythmia (P < 0.0001), previous hospitalization for heart failure (P < 0.0007), and were more likely hospitalized for COVID-19 (P < 0.0001). By multivariable logistic regression, prior anticoagulation (OR: 4.92; 95% CI: 2-11.76; P = 0.0003), cardiac injury (OR: 5.34; 95% CI: 1.98-14.76; P = 0.0009), and severe COVID-19 (OR: 17.39; 95% CI: 6.67-45.32; P < 0.0001) were independently associated with increased risk of TE/bleeding complications. Conclusions: ACHD patients with TE/bleeding during COVID-19 infection have a higher in-hospital mortality from the illness. Risk of coagulation disorders is related to severe COVID-19, cardiac injury during infection, and use of anticoagulants.

Anatomical/Physiological Correlates of Functional Capacity in Adults With Repaired and Nonsevere Coarctation of the Aorta.

Background: There is limited data regarding the interplay of anatomic and physiologic parameters with exercise capacity in adults with native or recurrent nonsevere coarctation of the aorta (CoA). Objectives: The objective of this study was to use exercise stress echocardiography and cardiac magnetic resonance imaging to identify anatomic and physiologic correlates of exercise capacity in these patients. Methods: We conducted a single-center retrospective analysis of 54 adults with nonsevere CoA (repaired or unrepaired) followed at our institution between 2015 and 2020. Resting coarctation gradients were obtained using echocardiography. Exercise gradients and functional capacity were assessed using exercise stress echocardiography. Aorta anatomy was obtained using magnetic resonance imaging. Results: Coarctation-to-diaphragm ratio correlated with minutes of exercise (r = 0.56, P < 0.01) and metabolic equivalents (r = 0.49, P < 0.01). These relationships remained significant after controlling for use of beta-blockers, valvular disease, and type of coarctation repair. Minutes of exercise correlated with mean resting gradients (r = -0.39, P < 0.05). Coarctation-to-diaphragm ratio correlated with peak and mean resting gradients (r = -0.34, P < 0.05; r = -0.48, P < 0.01). Patients with coarctation-to-diaphragm ratio ≤0.7 achieved fewer metabolic equivalents (11.1 ± 1.9 vs 12.8 ± 2.2, P < 0.05) and minutes of exercise (10.3 ± 2.0 vs 12.6 ± 2.7, P < 0.05). Conclusions: In patients with nonsevere native or recurrent CoA, reduced exercise capacity is correlated with coarctation severity by anatomic size and gradients. Those with a coarctation-to-diaphragm ratio ≤0.7 may represent a subset of patients with nonsevere CoA whose clinical symptoms are only elicited with exercise stress testing. Exercise stress testing and cross-sectional imaging may help identify those who could be considered for earlier coarctation intervention.

Adherence and Exercise Capacity Improvements of Patients With Adult Congenital Heart Disease Participating in Cardiac Rehabilitation.

Background As the number of adults with congenital heart disease increases because of therapeutic advances, cardiac rehabilitation (CR) is increasingly being used in this population after cardiac procedures or for reduced exercise tolerance. We aim to describe the adherence and exercise capacity improvements of patients with adult congenital heart disease (ACHD) in CR. Methods and Results This retrospective study included patients with ACHD in CR at New York University Langone Rusk Rehabilitation from 2013 to 2020. We collected data on patient characteristics, number of sessions attended, and functional testing results. Pre-CR and post-CR metabolic equivalent task, exercise time, and maximal oxygen uptake were assessed. In total, 89 patients with ACHD (mean age, 39.0 years; 54.0% women) participated in CR. Referral indications were reduced exercise tolerance for 42.7% and post-cardiac procedure (transcatheter or surgical) for the remainder. Mean number of sessions attended was 24.2, and 42 participants (47.2%) completed all 36 CR sessions. Among participants who completed the program as well as pre-CR and post-CR functional testing, metabolic equivalent task increased by 1.3 (95% CI, 0.7-1.9; baseline mean, 8.1), exercise time increased by 66.4 seconds (95% CI, 21.4-111.4 seconds; baseline mean, 536.1 seconds), and maximal oxygen uptake increased by 2.5 mL/kg per minute (95% CI, 0.7-4.2 mL/kg per minute; baseline mean, 20.2 mL/kg per minute). Conclusions On average, patients with ACHD who completed CR experienced improvements in exercise capacity. Efforts to increase adherence would allow more patients with ACHD to benefit.

Isolated Anomalous Right Superior Pulmonary Venous Return to the Inferior Vena Cava.

Partial anomalous pulmonary venous connection is a rare congenital abnormality. We present images from an atypical case of isolated anomalous right superior pulmonary venous return to the inferior vena cava without other cardiac abnormalities.

Acquired pulmonary vein stenosis resulting in haemoptysis: a case series.

BACKGROUND: Acquired pulmonary vein stenosis (PVS) is an infrequent complication of atrial fibrillation ablation that is often misdiagnosed due to predominant respiratory symptoms. It can result in pulmonary venous hypertension, with varying presentations, ranging from shortness of breath to haemoptysis. CASE SUMMARY: We report two patients with a history of paroxysmal atrial fibrillation treated with radiofrequency ablation and pulmonary vein (PV) isolation, who subsequently developed PVS. Case 1 initially presented with indolent symptoms of shortness of breath and cough. He was initially diagnosed with and treated for pneumonia. In contrast, Case 2 presented with massive haemoptysis, requiring intubation and intensive care unit admission. Both patients were eventually diagnosed with PVS by computed tomography. They were treated with PV angioplasty and stenting. DISCUSSION: While previously limited to the congenital heart disease population, PVS is occurring more frequently now in adult patients as a complication of ablation procedures. It is most effectively treated with angioplasty and stent implantation but has a high rate of recurrence.

COVID-19 in Adults With Congenital Heart Disease.

BACKGROUND: Adults with congenital heart disease (CHD) have been considered potentially high risk for novel coronavirus disease-19 (COVID-19) mortality or other complications. OBJECTIVES: This study sought to define the impact of COVID-19 in adults with CHD and to identify risk factors associated with adverse outcomes. METHODS: Adults (age 18 years or older) with CHD and with confirmed or clinically suspected COVID-19 were included from CHD centers worldwide. Data collection included anatomic diagnosis and subsequent interventions, comorbidities, medications, echocardiographic findings, presenting symptoms, course of illness, and outcomes. Predictors of death or severe infection were determined. RESULTS: From 58 adult CHD centers, the study included 1,044 infected patients (age: 35.1 ± 13.0 years; range 18 to 86 years; 51% women), 87% of whom had laboratory-confirmed coronavirus infection. The cohort included 118 (11%) patients with single ventricle and/or Fontan physiology, 87 (8%) patients with cyanosis, and 73 (7%) patients with pulmonary hypertension. There were 24 COVID-related deaths (case/fatality: 2.3%; 95% confidence interval: 1.4% to 3.2%). Factors associated with death included male sex, diabetes, cyanosis, pulmonary hypertension, renal insufficiency, and previous hospital admission for heart failure. Worse physiological stage was associated with mortality (p = 0.001), whereas anatomic complexity or defect group were not. CONCLUSIONS: COVID-19 mortality in adults with CHD is commensurate with the general population. The most vulnerable patients are those with worse physiological stage, such as cyanosis and pulmonary hypertension, whereas anatomic complexity does not appear to predict infection severity.

"Hot Septum" Sign of Constrictive Pericarditis.

In patients with constrictive pericarditis, a characteristic reduction in the regional longitudinal strain seen in the areas of the left ventricular free wall and relative sparing of the septal longitudinal strain values create an easily recognizable bullseye plot pattern that can be described as "hot septum." (Level of Difficulty: Beginner.).

Use of Medication for Cardiovascular Disease During Pregnancy: JACC State-of-the-Art Review.

Cardiovascular disease complicating pregnancy is rising in prevalence secondary to advanced maternal age, cardiovascular risk factors, and the successful management of congenital heart disease conditions. The physiological changes of pregnancy may alter drug properties affecting both mother and fetus. Familiarity with both physiological and pharmacological attributes is key for the successful management of pregnant women with cardiac disease. This review summarizes the published data, available guidelines, and recommendations for use of cardiovascular medications during pregnancy. Care of the pregnant woman with cardiovascular disease requires a multidisciplinary team approach with members from cardiology, maternal fetal medicine, anesthesia, and nursing.

Echocardiography before and after resect-plicate-release surgical myectomy for obstructive hypertrophic cardiomyopathy.

BACKGROUND: Anatomic features of obstructive hypertrophic cardiomyopathy are septal hypertrophy, elongated mitral leaflets, and anterior displacement of the papillary muscles. In addition to extended myectomy, the resect-plicate-release operation adds horizontal plication of the anterior mitral leaflet (AML) and release of the anterolateral papillary muscle (APM) in selected patients. The aim of this study was to test the hypotheses that (1) preoperative findings would be associated with procedures applied, (2) anatomic corrections would be observable postoperatively, and (3) there would be consistently good physiologic outcomes. METHODS: A retrospective study was conducted of patients with obstructive hypertrophic cardiomyopathy who had adequate echocardiograms before and 9.5 ± 12 months after the resect-plicate-release operation was performed from 2006 to 2012. RESULTS: Seventy-seven patients underwent myectomy, 50 AML plication, and 50 APM release. Patients who underwent plication had longer AMLs (32 ± 4 vs 28 ± 4 mm; P < .004). Anterior extension of the APM was more common with papillary muscle release (86% vs 62%, P < .04). Twenty-seven (35%) had septal thickness ≤ 18 mm; mitral valve-sparing operations were possible because of plication in 19 patients (70%), papillary release in 21 (78%), and one or both in 96%. Patients who underwent plication had decreased AML length by 16%, residual leaflet length by 33%, and protrusion by 24%. After APM release, there was decreased distance from mitral coaptation to the posterior wall. Surgery abolished severe systolic anterior motion and resting gradients and reduced mitral regurgitation. CONCLUSIONS: Echocardiographic AML length and directly observed slack provides a basis to recommend performance of plication and define its extent; plication decreases AML protrusion and stiffens the leaflet. Anterior APM recommends release, which drops the coaptation point posteriorly. Systematic relief of all aspects of obstructive pathophysiology results in consistent outcomes.

Cardiac Calcifications in Adults with Congenital Heart Defects.

OBJECTIVE: We investigated the type and extent of calcification in a series of heart specimens from adult congenital heart disease patients because recent autopsy observations suggested a high prevalence of calcification. DESIGN: We used computed tomography to examine seven heart specimens from adults (>18 years old) with a congenital heart defect collected with permission from the family during a recent 3-year period. Clinical data regarding diagnosis, history, and imaging studies were recorded. The 3D data sets were reviewed after reformatting as maximum intensity projection and volumetric renderings to determine the pattern and extent of calcium deposition. RESULTS: Five of the seven hearts had extensive calcifications in one or more of three patterns: atherosclerosis associated in the three oldest cases; surgery associated in four of five hearts that had undergone heart surgery; and myocardial calcification remote from surgical sites in two cases. Myocardial calcification was associated with regional dysfunction and was present in the three patients that died suddenly and unexpectedly. CONCLUSION: Cardiac calcification was frequent in our series of heart specimens from adults with congenital heart defects, was often but not uniformly associated with prior surgery, and, in our small series, was associated with regional dysfunction and sudden death.
