RESUMO

BACKGROUND: Symptoms, imaging characteristics, and early and midterm surgical outcomes for aberrant subclavian arteries (ASCA) are not well defined in the adult population. METHODS: A single-institution retrospective review was conducted of adults undergoing surgical repair of ASCA and descending aorta origin/Kommerell diverticulum (KD) from January 1, 2002, to December 31, 2021. Symptom improvement and differences in imaging characteristics between anatomic groups and the number of symptoms were assessed. RESULTS: Mean age was 46 ± 17 years. There were 23 of 37 left aortic arches with right ASCA (62%) and 14 of 37 right aortic arches with left ASCA (38%). Of these, 31 of 37 (84%) were symptomatic, and 19 of 37 (51%) had KD size/growth meeting criteria for surgical repair. KD aortic origin diameter was larger in more symptomatic patients: 20.60 mm (interquartile range [IQR], 16.42-30.68 mm) in patients with ≥3 symptoms vs 22.05 mm (IQR, 17.52-24.21 mm) for 2 symptoms vs 13.72 mm (IQR, 12.70-15.95 mm) for 1 symptom (P = .018). Aortic replacement was required in 22 of 37 (59%). There were no early deaths. Complications occurred in 11 of 37 (30%): vocal cord dysfunction (4 of 37 [11%]), chylothorax (3 of 37 [8%]), Horner syndrome (2 of 37 [5%]), spinal deficit (2 of 37 [5%]), stroke (1 of 37 [3%]), and temporary dialysis requirement (1 of 37 [3%]). Over a median follow-up of 2.3 years (IQR, 0.8-3.9 years), there was 1 endovascular reintervention and no reoperations. Dysphagia and shortness of breath resolved in 92% and 89%, respectively, whereas gastroesophageal reflux persisted in 47%. CONCLUSIONS: The KD aortic origin diameter correlates with the number of symptoms, and surgical repair of ASCA and descending aorta origin/KD effectively relieves symptoms, with low rates of reintervention. Given the operative complexity, surgical repair should be performed in patients meeting size criteria or with significant dysphagia or shortness of breath symptoms.

RESUMO

BACKGROUND: There are limited data about the stage D heart failure (advanced HF) in adults with congenital heart disease. Our study objectives were (1) to determine the incidence of new-onset advanced HF in patients and the relationship between advanced HF and all-cause mortality and (2) to determine the relationship between therapies for advanced HF and all-cause mortality. METHODS: Retrospective cohort study of adults with congenital heart disease at Mayo Clinic (2003-2019). We defined advanced HF using the European Society of Cardiology diagnostic criteria for advanced HF. Therapies received by the patients with advanced HF were classified into 3 mutually exclusive groups (treatment pathways): (1) conventional cardiac intervention, (2) transplant listing, and (3) palliative care. RESULTS: Of 5309 patients without advanced HF at baseline assessment, 432 (8%) developed advanced HF during follow-up (1.1%/y), and the incidence of advanced HF was higher in patients with severe or complex congenital heart disease. Onset of advanced HF was associated with 6-fold increase in the risk of mortality. Conventional cardiac intervention was associated with significantly higher risk of mortality as compared to transplant listing. The longer the interval from the initial onset of advanced HF to transplant evaluation, the lower the odds of being listed for transplant. CONCLUSIONS: Based on these data, we postulate that early identification of patients with advanced HF, and a timely referral for transplant evaluation (instead of conventional cardiac intervention) may offer the best chance of survival for these critically ill patients. Further studies are required to validate this postulation.

RESUMO

AIMS: Conotruncal anomalies share common embryogenic defects of the outflow tracts and great arteries, which result in a predisposition to aortic aneurysms. The purpose of this study was to describe the prevalence and risk of progressive aortic aneurysms in adults with conotruncal anomalies. METHODS AND RESULTS: Retrospective study of adults with conotruncal anomalies that underwent cross-sectional imaging 2003-20. Aneurysm was defined as aortic root/mid-ascending aorta >2.1 mm/m2/>1.9 mm/m2, progressive aneurysm as increase by >2 mm, and severe aneurysm as dimension >50 mm. Of 2261 patients (38 ± 12 years; male 58%), 1167 (52%) had an aortic aneurysm, and 205 (14%) had a severe aortic aneurysm. Mean annual increase in aortic root/mid-ascending aorta was 0.3 ± 0.1 mm/0.2 ± 0.1 mm. The 3-, 5-, and 7-year cumulative incidence of the progressive aortic aneurysm was 4%, 7%, and 9%, respectively. The rate of aneurysm growth decreased with age, with no significant growth after age 40 years. There was an excellent correlation between aortic indices from cross-sectional imaging and echocardiography. Of 950 females, 184 had ≥1 pregnancy, and 81 (44%) of the 184 patients had aortic aneurysm prior to pregnancy. There was no aortic dissection or progression of the aortic aneurysm during pregnancy. Overall, there was no aortic dissection during 7984 patient-years of follow-up. CONCLUSIONS: Aortic aneurysm was common in patients with conotruncal anomalies. However, the risk of progressive aneurysm or dissection was low. Collectively, these data suggest a benign natural history and perhaps a less frequent need for cross-sectional imaging. Further studies are required to determine the optimal timing for surgical intervention in this population.

RESUMO

BACKGROUND: Cardiovascular surgical outcomes reports are few for vascular type IV of Ehlers- Danlos Syndrome (vEDS) compared to non-vascular types I-III (nEDS). METHODS: To define cardiovascular surgical outcomes among adult patients (≥18 years) with EDS types, a review of our institution's in-house STS Adult Cardiac Surgery Database-compliant software and electronic medical records from Mayo Clinic (1993-2019) was performed. Outcomes were compared for vEDS patients and nEDS patients. Demographics, baseline characteristics, operative, in-hospital complications and follow-up vital status were analyzed. RESULTS: Over the study time frame, 48 EDS patients underwent surgery (mean age 52.6 ± 14.6 years; 48% females). Of these, 17 patients had vEDS and 31 patients had nEDS. Six patients (12.5%) underwent prior sternotomy. Urgent or emergent surgery was performed in 10 patients (20.8%). Aortic (vEDS 76.5% vs. nEDS 16.1%) and mitral procedures (vEDS 11.8% vs. nEDS 48.4%) were the two most common cardiovascular surgeries performed (p < .01 and p = .007, respectively). Cardiopulmonary bypass time (CPB) (165 ± 18 vs. 90 ± 13 min; p = .015) and aortic cross clamp times (140 ± 14 vs. 62 ± 10 min; p < .001) were longer for vEDS patients. There was 1 (2.1%) early and 7 (14.6%) late deaths; 6 among vEDS and 2 among nEDS patients. Survival at 5 (80% vs. 93%), 10 (45% vs. 84%) and 15 years (45% vs. 84%) was lower in patients with vEDS (p = .015 for each comparison). CONCLUSION: Cardiovascular surgeries are significantly more complex with longer bypass and cross clamp times for type IV vEDS compared to nEDS patients. Reduced overall survival underscores the complexity and fragility of vEDS patients.

RESUMO

OBJECTIVE: To report the early postoperative outcomes in adults with tetralogy of Fallot (TOF) undergoing cardiac surgery and to identify patient factors associated with complications. PATIENTS AND METHODS: We performed a single-institution retrospective review of adults with TOF who underwent cardiac surgery from January 8, 2008, through June 21, 2018. Patients' characteristics, preoperative imaging, surgical interventions, outcomes, and complications were analyzed. RESULTS: There were 219 adults with TOF (mean age, 40 years; range, 18-83 years; 88 [40%] female) in the study. Surgical interventions included repair or replacement of the pulmonary valve (n=199 [91%]), tricuspid valve (n=70 [32%]), mitral valve (n=13 [5.9%]), and aortic valve (n=8 [3.7%]). Three patients (1.4%) underwent first-time TOF repair. The 30-day mortality rate was 1.4% (n=3). Early postoperative complications occurred in 66 (30%) and included arrhythmias requiring treatment, dialysis requirement, liver dysfunction, respiratory failure, infection, reoperation, cardiac arrest, mechanical circulatory support, and death. Multivariate analysis found older age at current surgery (odds ratio [OR], 1.04 per year; 95% CI, 1.01 to 1.06; P<.001), longer cardiopulmonary bypass time (OR, 1.01 per minute; 95% CI, 1.01 to 1.02; P<.001), right ventricular systolic dysfunction (OR, 1.31; 95%, CI 1.02 to 1.69; P=.03), diabetes mellitus (OR, 3.50; 95% CI, 1.20 to 10.2; P=.02), and history of initial palliative surgery (OR, 1.99; 95% CI, 1.01 to 3.91; P=.05) as independent predictors of complications. CONCLUSION: Surgical interventions for adult patients with TOF can be performed with low early morbidity and mortality. Clinical characteristics and preoperative testing parameters can predict risk for complications in the postoperative period.

RESUMO

BACKGROUND: Pulmonary artery wedge pressure (PAWP) is often elevated in patients with right-sided congenital heart disease (CHD), raising the possibility of coexisting left-heart disease, but pressure-volume relationships in the left and right sides of the heart influence one another through interdependence, which may be amplified in patients with CHD. METHODS: We hypothesized that increases in PAWP in patients with CHD would be more strongly related to ventricular interdependence compared with patients who have isolated left-heart disease such as heart failure with preserved ejection fraction (HFpEF). Ventricular interdependence was assessed by the relationship between PAWP and right-atrial pressure (RAP), RAP/PAWP ratio, and the left-ventricular (LV) eccentricity index. RESULTS: PAWP was elevated (≥15 mm Hg) in 49% of patients with CHD (n = 449). There was a very strong correlation between RAP and PAWP in CHD (r = 0.81, P < 0.001) that greatly exceeded the respective correlation in HFpEF (n = 160; r = 0.58, P < 0.001; P < 0.001 between groups). RAP/PAWP ratio and LV eccentricity index were higher in CHD than HFpEF (1.26 ± 0.18 vs 1.05 ± 0.14, P = 0.007) and (0.80 ± 0.21 vs 0.59 ± 0.19, P < 0.001), respectively. RAP (but not PAWP) was an independent predictor of death/transplant (hazard ratio 1.86 per 5 mm Hg, 95% confidence interval, 1.39-2.45, P = 0.002). CONCLUSIONS: Left-heart filling pressures are commonly elevated in right-sided CHD, but this is related predominantly to right-heart failure and enhanced ventricular interdependence rather than left-heart disease. These data provide new insight into the basis of abnormal left-heart hemodynamics in patients with CHD and reinforce the importance of therapeutic interventions targeted to the right heart.

RESUMO

Repair of Ebstein anomaly has evolved over the last decade, and timing of repair remains variable. There have been no studies of exercise or functional capacity in patients who have had tricuspid valve surgery for Ebstein anomaly in adulthood. We aimed to compare exercise capacity before and after tricuspid valve repair or replacement for Ebstein anomaly in adults at Mayo Clinic. We performed a retrospective chart review of all patients with Ebstein anomaly who underwent tricuspid valve surgery at Mayo Clinic between June 2007 and January 2015. We compared pre- and postoperative echocardiograms, exercise tests, and clinic visits. Tricuspid valve surgery was done for 322 patients, and 32 patients met criteria of native tricuspid valve repair or replacement at age 18 or older and had maximal pre- and postoperative exercise tests. Nineteen patients had valve repair, and 13 had valve replacement. Surgery for Ebstein anomaly resulted in significant reduction in tricuspid regurgitation and right ventricular size. There was a significant improvement in NYHA functional class after surgery; however, there was no significant improvement in functional aerobic capacity (FAC), metabolic equivalents (METs), exercise time, or [Formula: see text] after surgery. Patients who had an atrial shunt closed during surgery had improved minimum blood oxygen saturations during exercise, though no improvement in exercise capacity. In our cohort, patients who had tricuspid valve repair or replacement for Ebstein anomaly reported an improvement in functional capacity; however, this did not reflect improvement in measured exercise capacity, despite excellent surgical results by echocardiography.

RESUMO

BACKGROUND: Placental insufficiency may be the cause of the high preterm birth rate in women after Fontan operation. In this study we reviewed the clinical course and pregnancy outcome of women with Fontan physiology with a focus on placental pathology. METHODS: We reviewed clinical charts and placental pathology from 7 women with Fontan physiology who had pregnancies at Mayo Clinic, Rochester, Minnesota. The review was limited to cases where placental pathologic specimens were rigorously examined. RESULTS: Seven women had 13 deliveries between 2002 and 2018. Only 2 of 13 deliveries were at term (>37 weeks). Mean maternal age at time of last delivery was 27.5 ±â€¯3.2 years. Preeclampsia was noted during 2 pregnancies and 2 women had preterm premature rupture of membranes at 24 and 35 weeks gestation, respectively. Placental abruption with bleeding occurred in 2 pregnancies. An additional 4 pregnancies were complicated by intrauterine growth restriction (IUGR). Median placental weight was 441.5 g (IQR 305.5-622.5 g). Median placental weight percentile for gestational age was 10th to 25th, but varied greatly; two placentas were <10th percentile and 5 were >90th percentile for gestational age. Two umbilical cords contained a single umbilical artery. Prominent subchorionic fibrin deposition was a consistent feature in all placentas. Villous hypermaturity was noted in 4 placentas. CONCLUSIONS: Fontan physiology may be associated with poor placental health. High systemic venous pressure and low cardiac output may contribute to stagnation of placental blood flow and result in subchorionic fibrin deposition and variable villous hypoplasia. This may explain the high preterm birth rate in women with Fontan physiology. Preterm deliveries and small-for-gestational-age (SGA) newborns should be anticipated in this patient population. Analysis of placental pathology may help determine both candidacy for future pregnancy and long-term effects of pregnancy for women with Fontan physiology.

RESUMO

BACKGROUND: Ascending aorta dilatation is common in bicuspid aortic valve (BAV). The aim of this study was to investigate agreement of transthoracic echocardiographic (TTE) measurement of the sinuses of Valsalva and the tubular mid-ascending aorta (Asc-Ao) compared with electrocardiographically gated computed tomographic angiographic (CTA) assessment in patients with BAV. METHODS: Fifty-three patients with BAV (mean age, 54 ± 14 years; 74% men) who underwent both TTE and CTA imaging for ascending aortic assessment were retrospectively identified. All studies were measured de novo by experts. TTE measurements were obtained at the sinuses and the Asc-Ao, at both systole and end-diastole, using both leading edge-to-leading edge (L-L) and inner edge-to-inner edge (I-I) methods in the parasternal long-axis (LAX) view. The sinuses were also measured in the parasternal short-axis (SAX) view using the same methods plus mid-diastole. CTA measurements were obtained in diastole using outer wall-to-outer wall (O-O) and inner wall-to-inner wall (I-I) methods. Correlation and agreement between the two imaging modalities were assessed using Lin correlation and Bland-Altman analysis, respectively. RESULTS: Compared with CTA O-O maximum sinuses diameter, the best correlation and agreement were obtained using the TTE SAX mid-diastolic L-L method (ρ = 0.89, 2.6 ± 2.3 mm, respectively). Compared with CTA O-O maximum Asc-Ao diameter, the TTE LAX systolic L-L method (ρ = 0.93, 1.3 ± 2.5 mm) was best. Compared with CTA I-I maximum sinuses diameter, the TTE SAX mid-diastole L-L method (ρ = 0.95, 0.6 ± 2.2 mm) was unbiased. Compared with CTA I-I maximum Asc-Ao diameter, the TTE LAX end-diastolic L-L method (ρ = 0.95, 0.6 ± 2.4 mm) was unbiased. CONCLUSIONS: In patients with BAV aortopathy, unbiased agreement between CTA and TTE imaging can be obtained between the CTA I-I method and TTE SAX mid-diastolic L-L method for the sinuses and the TTE LAX end-diastolic L-L method for the Asc-Ao. When using the CTA O-O method, the best agreement is obtained with the TTE SAX mid-diastolic L-L method for the sinuses (bias ∼2 mm) and the TTE LAX systolic L-L method (bias ∼1 mm) for the Asc-Ao.

RESUMO

BACKGROUND: To determine if Fontan conversion (FC) resulted in improvement in exercise capacity (EC), and to determine the role of cardiopulmonary exercise test (CPET) in risk stratification of patients undergoing FC. METHODS: A retrospective review of patients who underwent CPET prior to FC at Mayo Clinic from 1994 to 2014. The patients who also underwent post-operative CPET were selected for the analysis of improvement in EC defined as 10% increase in baseline peak oxygen consumption (VO2). RESULTS: 75 patients CPET prior to FC; mean age 24±6years; 44 males (59%); and 51 (68%) were in NYHA III/IV prior to FC. Pre-operative peak VO2 was 15.5±3.4ml/kg/min. A comparison of pre- and post-FC CPET data was performed using 42 patients (56%) that underwent CPET after FC. Improvement in EC occurred in 18 of 42 patients (43%). Baseline peak VO2 >14ml/kg/min was associated with improved EC (hazard ratio [HR] 1.85; P=.02). Improvement in New York Heart Association (NYHA) class occurred in 12 (67%) patients with improved EC vs 2 (8%) without improved EC. Improvement in NYHA class was more likely to occur in patients with improved EC compared to those without improvement EC (odds ratio 4.11, P=.01). There were 10 (13%) perioperative deaths, and baseline peak VO2 ≤14ml/kg/min was predictive of perioperative mortality (HR 3.74; P<.001). CONCLUSIONS: Baseline peak VO2 was predictive of perioperative survival, and improvement in EC. Performance on CPET in failing Fontan patients might be a useful clinical parameter in determining appropriate timing of FC.

RESUMO

AIMS: To review clinical and microbiological findings in adults with prosthetic pulmonary valve (PPV) or right ventricle to pulmonary artery conduit (RVPAC) infective endocarditis (IE) and to assess the yield of transthoracic (TTE) and transesophageal echocardiography (TEE) as diagnostic tools. METHODS AND RESULTS: Seventeen adults (age ≥18 years) with PPV/RVPAC who met diagnostic criteria for definite IE between 2000 and 2015 were included. Median age was 34 years and 29% were females; four patients (24%) had a previous episode of IE. IE occurred a median interval of 5.3 years after PPV/RVPAC insertion; median follow-up time was 206 days. The most common organisms were Staphylococcus aureus (29%), coagulase-negative staphylococci (24%), and streptococcal species (24%). Eleven patients (64.5%) required PPV/RVPAC replacement surgery as consequence of the IE episode. There were three deaths during follow-up; one non-operative and two post-operative. TTE was diagnostic for PPV/RVPAC IE in 10 (62%) and TEE was diagnostic in eight (57%) patients; when combined TTE/TEE were diagnostic in 15 of 17 (88%) cases. Severe PPV/RVPAC obstruction was present at the time of IE diagnosis in nine (53%) and severe regurgitation in five (29%). CONCLUSION: PPV/RVPAC IE is associated with significant morbidity, mortality and high risk of requiring operative intervention. TTE and TEE are marginal diagnostic tools when used independently; they should be used as complementary techniques in the evaluation of those patients. Severe PPV/RVPAC stenosis was more common than regurgitation in patients with IE; thus IE should be considered in patients presenting with new PPV/RVPAC obstruction.

RESUMO

BACKGROUND: The subcutaneous implantable cardioverter defibrillator (S-ICD) provides an attractive option for patients with congenital heart disease (CHD) in whom a transvenous defibrillator is contraindicated. Given the unusual cardiac anatomy and repolarization strain, the surface electrocardiogram (ECG) is frequently abnormal, potentially increasing the screen failure rate. METHODS AND RESULTS: We prospectively screened 100 adult CHD patients regardless of the presence of clinical indication for ICD utilizing a standard left sternal lead placement, as well as a right parasternal position. Baseline patient and 12-lead ECG characteristics were examined to assess for predictors of screen failure. Average patient age was 48±14 years, average QRS duration was 134±37 ms, and 13 patients were pacemaker dependent. Using the standard left parasternal electrode position, 21 patients failed screening. Of these 21 patients with screen failure, 9 passed screening with the use of right parasternal electrode positioning, reducing screening failure rate from 21% to 12%. QT interval and inverted T wave anywhere in V2-V6 leads were found to be independent predictors of left parasternal screening failure (P=0.01 and P=0.04, respectively). CONCLUSIONS: Utilization of both left and right parasternal screening should be used in evaluation of CHD patients for S-ICD eligibility. ECG repolarization characteristics were also identified as novel predictors of screening failure in this group. (Circ J 2016; 80: 1328-1335).

RESUMO

OBJECTIVE: The feasibility and safety of pregnancy after the Fontan operation is not well understood. We sought to determine contraception practices and early and late outcomes of pregnancy after the Fontan operation. DESIGN: We performed a retrospective review of medical records to identify women of childbearing age from the Mayo Clinic Fontan database. A follow-up questionnaire was mailed to all patients not known to be deceased at the time of study. Patients with available contraception and pregnancy data were included in the study. RESULTS: Of the 138 women with available contraception data, 44% used no contraception, 12% each used barrier methods, combination hormone therapy or sterilization, 8% used Depo-Provera, 7% had intrauterine devices, 4% had a partner with a vasectomy and 1% used progestin pills. Six women had thrombotic complications (only one using oral contraceptives). Thirty-five women had pregnancy data available. Prior to the Fontan operation there were 10 pregnancies (8 miscarriages, 2 therapeutic abortions, and no live births). After the Fontan operation there were 70 pregnancies resulting in 35 miscarriages (50%), 29 live births (41%), and 6 therapeutic abortions (9%). There were no maternal deaths during pregnancy. During long-term follow up (26 ± 6 years since the Fontan), 1 death, and 1 cardiac transplant occurred. Mean gestational age of the newborns (n = 22/29) was 33.1 ± 4.0 weeks; mean birth weight (n = 20/29) was 2086 ± 770 g. There was 1 neonatal death because of prematurity and two children were born with congenital heart disease (one patent ductus arteriosus and one membranous ventricular septal defect). CONCLUSIONS: Pregnancy after the Fontan operation is associated with a high rate of miscarriages, preterm delivery, and low birth weight. Further studies are needed to identify specific variables influencing risk stratification of pregnancy in this patient population.

RESUMO

OBJECTIVE: To evaluate the utility of magnetic resonance elastography (MRE) in screening patients for hepatic fibrosis, cirrhosis, and hepatocellular carcinoma after the Fontan operation. PATIENTS AND METHODS: Hepatic MRE was performed in conjunction with cardiac magnetic resonance imaging in patients who had undergone a Fontan operation between 2010 and 2014. Liver stiffness was calculated using previously reported techniques. Comparisons to available clinical, laboratory, imaging, and histopathologic data were made. RESULTS: Overall, 50 patients at a median age of 25 years (range, 21-33 years) who had undergone a Fontan operation were evaluated. The median interval between Fontan operation and MRE was 22 years (range, 16-26 years). The mean liver stiffness values were increased: 5.5 ± 1.4 kPa relative to normal participants. Liver stiffness directly correlated with liver biopsy-derived total fibrosis score, time since operation, mean Fontan pressure, γ-glutamyltransferase level, Model for End-Stage Liver Disease score, creatinine level, and pulmonary vascular resistance index. Liver stiffness was inversely correlated with cardiac index. All 3 participants with hepatic nodules exhibiting decreased contrast uptake on delayed postcontrast imaging and increased nodule stiffness had biopsy-proven hepatocellular carcinoma. CONCLUSION: The association between hepatic stiffness and fibrosis scores, Model for End-Stage Liver Disease scores, and γ-glutamyltransferase level suggests that MRE may be useful in detecting (and possibly quantifying) hepatic cirrhosis in patients after the Fontan operation. The correlation between stiffness and post-Fontan time interval, mean Fontan pressure, pulmonary vascular resistance index, and reduced cardiac index suggests a role for long-term hepatic congestion in creating these hepatic abnormalities. Magnetic resonance elastography was useful in detecting abnormal nodules ultimately diagnosed as hepatocellular carcinoma. The relationship between stiffness with advanced fibrosis and hepatocellular carcinoma provides a strong argument for additional study and broader application of MRE in these patients.
