Clinical impact of right ventricular-pulmonary artery uncoupling on predicting the clinical outcomes after catheter ablation in persistent atrial fibrillation patients. IJC HEART & VASCULATURE 2022; 39:100991. [PMID: 35281759 PMCID: PMC8904595 DOI: 10.1016/j.ijcha.2022.100991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 02/14/2022] [Accepted: 03/01/2022] [Indexed: 12/02/2022]
Abstract
Background Right ventricular (RV)-pulmonary artery (PA) uncoupling is associated with poor outcomes in heart failure patients. We aimed to elucidate the relationship between RV-PA uncoupling and late arrhythmia recurrence after ablation in persistent atrial fibrillation (PerAF) patients whose phenotypes have impaired right ventricular function and pulmonary hypertension. Methods The present study included 203 PerAF patients from the Osaka Rosai Atrial Fibrillation ablation (ORAF) registry who underwent an initial ablation. We assigned the patients based on the value of tricuspid annular plane systolic excursion (TAPSE)/pulmonary artery systolic pressure (PASP) ratio that could predict late recurrence of AF/atrial tachycardia (LRAF) as an indicator of RV-PA uncoupling. We evaluated the following factors: the difference in the relationship between TASPE/PASP before ablation and incidence of LRAF among the 2 groups stratified by TAPSE/PASP based on the above cut-off value and TAPSE/PASP change from before to one-year after ablation. Results A receiver operating characteristic curve analysis revealed a good accuracy of predicting LRAF by TAPSE/PASP ratio with a cutoff of 0.57. The patients with TAPSE/PASP ratios ≤ 0.57 had a significantly greater LRAF risk than TAPSE/PASP ratios > 0.57. A multivariate Cox proportional hazards analysis showed that TAPSE/PASP (HR 0.12, 95% CI; 0.019–0.724, p = 0.026) was independently and significantly associated with LRAF. The TAPSE/PASP significantly improved more one-year after the ablation than before (p = 0.016). Conclusion RV-PA uncoupling was independently associated with LRAF, independent of left atrial function, and significantly improved more one-year after the ablation than before in PerAF patients.

Renal Venous Stasis Index Reflects Renal Congestion and Predicts Adverse Outcomes in Patients With Heart Failure. Front Cardiovasc Med 2022; 9:772466. [PMID: 35321106 PMCID: PMC8934863 DOI: 10.3389/fcvm.2022.772466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 02/10/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundIt has been recently reported that the renal venous stasis index (RVSI) assessed by renal Doppler ultrasonography provides information to stratify pulmonary hypertension that can lead to right-sided heart failure (HF). However, the clinical significance of RVSI in HF patients has not been sufficiently examined. We aimed to examine the associations of RVSI with parameters of cardiac function and right heart catheterization (RHC), as well as with prognosis, in patients with HF.MethodsWe performed renal Doppler ultrasonography, echocardiography and RHC in hospitalized patients with HF (n = 388). RVSI was calculated as follows: RVSI = (cardiac cycle time-venous flow time)/cardiac cycle time. The patients were classified to three groups based on RVSI: control group (RVSI = 0, n = 260, 67%), low RVSI group (0 < RVSI ≤ 0.21, n = 63, 16%) and high RVSI group (RVSI > 0.21, n = 65, 17%). We examined associations of RVSI with parameters of cardiac function and RHC, and followed up for cardiac events defined as cardiac death or worsening HF.ResultsThere were significant correlations of RVSI with mean right atrial pressure (mRAP; R = 0.253, P < 0.001), right atrial area (R = 0.327, P < 0.001) and inferior vena cava diameter (R = 0.327, P < 0.001), but not with cardiac index (R = −0.019, P = 0.769). During the follow-up period (median 412 days), cardiac events occurred in 60 patients. In the Kaplan–Meier analysis, the cumulative cardiac event rate increased with increasing RVSI (log-rank, P = 0.001). In the multivariate Cox proportional hazard analysis, the cardiac event rate was independently associated with RVSI (high RVSI group vs. control group: hazard ratio, 1.908; 95% confidence interval, 1.046–3.479, P = 0.035).ConclusionRVSI assessed by renal Doppler ultrasonography reflects right-sided overload and is associated with adverse prognosis in HF patients.
