Head-to-Head Comparison of Hepatic Vein and Superior Vena Cava Flow Velocity Waveform Analyses for Predicting Elevated Right Atrial Pressure. ULTRASOUND IN MEDICINE & BIOLOGY 2024:S0301-5629(24)00216-3. [PMID: 38834491 DOI: 10.1016/j.ultrasmedbio.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 04/27/2024] [Accepted: 05/10/2024] [Indexed: 06/06/2024]
Abstract
OBJECTIVE Blood flow in the hepatic veins and superior vena cava (SVC) reflects right heart filling; however, their Doppler profiles are often not identical, and no studies have compared their diagnostic efficacies. We aimed to determine which venous Doppler profile is reliable for detecting elevated right atrial pressure (RAP). METHODS In 193 patients with cardiovascular diseases who underwent cardiac catheterization within 2 d of echocardiography, the hepatic vein systolic filling fraction (HV-SFF) and the ratio of the peak systolic to diastolic forward velocities of the SVC (SVC-S/D) were measured. HV-SFF < 55% and SVC-S/D < 1.9 were regarded as elevated RAP. We also calculated the fibrosis 4 index (FIB-4) as a serum liver fibrosis marker. RESULTS HV-SFF and SVC-S/D were feasible in 177 (92%) and 173 (90%) patients, respectively. In the 161 patients in whom both venous Doppler waveforms could be measured, HV-SFF and SVC-S/D were inversely correlated with RAP (r = -0.350, p < 0.001; r = -0.430, p < 0.001, respectively). SVC-S/D > 1.9 showed a significantly higher diagnostic accuracy of RAP elevation compared with HV-SFF < 55% (area under the curve, 0.842 vs. 0.614, p < 0.001). Multivariate analyses showed that both FIB-4 (β = -0.211, p = 0.013) and mean RAP (β = -0.319, p < 0.001) were independent determinants of HV-SFF. In contrast, not FIB-4 but mean RAP (β = -0.471, p < 0.001) was an independent determinant of SVC-S/D. The diagnostic accuracy remained unchanged when HV-SFF < 55% was considered in conjunction with the estimated RAP based on the inferior vena cava morphology. Conversely, SVC-S/D showed an incremental diagnostic value over the estimated RAP. CONCLUSIONS SVC-S/D enabled a more accurate diagnosis of RAP elevation than HV-SFF.

Circ Cardiovasc Imaging 2022; 15:e014308.

Abstract
BACKGROUND Inferior vena cava (IVC) size and collapsibility (IVC dynamics) are used for estimating right atrial pressure (RAP). However, the diagnostic performance of the American Society of Echocardiography IVC criteria for estimating RAP in patients with congenital heart disease are unknown. The purpose of this study was to assess the role of IVC dynamics for estimating RAP in adults with congenital heart disease. METHODS We conducted a retrospective study of adults with congenital heart disease that underwent cardiac catheterization and echocardiogram at Mayo Clinic (2003-2019). IVC diameter was measured at inspiration (IVCmin) and end-expiration (IVCmax), and IVC collapsibility index (IVCCI) was calculated. RESULTS Based on 918 patients, we observed a good correlation between IVCmax and invasive RAP (r=0.56, P<0.001); IVCmin and RAP (r=0.58, P<0.001); and IVCCI (r=-0.72, P<0.001). There was excellent correlation between invasive RAP and estimated RAP using IVCCI (r=0.80, P<0.001). We observed that IVCCI <60% had superior diagnostic performance as compared with American Society of Echocardiography criteria (IVCmax >2.1 cm, area under the curve difference 0.15, P<0.001; IVCCI <50%, area under the curve difference 0.09, P=0.008; combination of IVCmax >2.1 cm; and IVCCI <50%, area under the curve difference 0.06, P=0.02). Estimated RAP >10 mm Hg based on IVCCI had comparable prognostic performance as invasive RAP but superior prognostic performance as the American Society of Echocardiography criteria. CONCLUSIONS IVCCI <60% was the best criterion to identify patients with elevated RAP. IVCCI was comparable to invasively measured RAP in its relation to prognosis. Further studies are required to determine whether the use of IVCCI in clinical decision-making will improve clinical outcomes in this population.

Abstract
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, p = .44) and cardiac output (2.2±0.6 vs. 2.0±0.4 L/min/m2, p = .23). There was no difference in transplant-free survival (p = .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.

Abstract
BACKGROUND Hepatorenal dysfunction is a risk factor for mortality in patients with chronic tricuspid regurgitation due to acquired heart disease. Ebstein anomaly is the most common cause of primary tricuspid regurgitation in adults with congenital heart disease, but the prevalence and prognostic implications of hepatorenal dysfunction are unknown in this population. OBJECTIVES The purpose of this study was to determine the risk factors and prognostic implications of hepatorenal dysfunction, as measured primarily by the use of model for end-stage liver disease excluding international normalized ratio (MELD-XI score), as well as looking at other associated factors. METHODS This was a retrospective study of adults with Ebstein anomaly who received care at Mayo Clinic from 2003 to 2018. RESULTS Of 692 patients, the median MELD-XI score was 10.2 (interquartile range: 9.4 to 13.3); 53 (8%) died and 3 (0.4%) underwent heart transplant. MELD-XI was an independent predictor of death/transplant (hazard ratio: 1.32; 95% confidence interval: 1.11 to 2.06; p < 0.001). In the subset of patients with serial MELD-XI scores (n = 416), temporal change in MELD-XI score (ΔMELD-XI) was also a predictor of death/transplant. In the subset of patients who underwent tricuspid valve surgery (n = 344), a post-operative improvement in MELD-XI score (ΔMELD-XI) was associated with improved long-term survival. Impaired right atrial (RA) reservoir strain and elevated estimated RA pressure were associated with worse baseline MELD-XI and ΔMELD-XI scores. CONCLUSIONS Hepatorenal dysfunction is a predictor of mortality in Ebstein anomaly, and RA dysfunction and hypertension are hemodynamic biomarkers that can identify patients at risk for deterioration in hepatorenal function and mortality. These data highlight the prognostic importance of noncardiac organ-system dysfunction, and provide complementary clinical risk stratification metrics for management of these patients.

Abstract
AIMS Right atrial pressure (RAP) provides a composite measure of right ventricular diastolic dysfunction, right atrial compliance, and volume status, and these three variables are typically abnormal in adults with repaired tetralogy of Fallot (TOF). RAP is a well-established prognostic metric in patients with pulmonary hypertension, and recent data suggest that RAP is associated with clinical outcomes in TOF. The purpose of this study was to determine the role of inferior vena cava (IVC) haemodynamics (size and collapsibility) for the assessment of RAP and its potential application for risk stratification and prognostication in the TOF population. METHODS AND RESULTS Adult TOF patients with echocardiographic assessment of IVC haemodynamics were divided into patients with (derivation cohort, n = 256) and without (validation cohort, n = 492) cardiac catheterization data. We assessed the correlation between IVC haemodynamics, RAP, and disease severity indices [arrhythmias, peak oxygen consumption (VO2 ), and heart failure hospitalization] in derivation cohort and compared it with the correlations in the validation cohort. IVC haemodynamics correlated with RAP (r = 0.52, P < 0.001), with disease severity indices {atrial arrhythmias [area under the curve (AUC) 0.81], ventricular arrhythmias [AUC 0.67], heart failure hospitalizations [AUC 0.78], and peak VO2 [r = 0.53]}, and with transplant-free survival in the derivation cohort. Similar correlations between IVC haemodynamics, disease severity indices, and transplant-free survival were also observed in the validation cohort. CONCLUSIONS These findings suggest that IVC haemodynamics can potentially be used for risk stratification and prognostication in TOF patients and can complement the current risk models that are based predominately on right ventricular volumes and systolic function.
