Cardiac power output is associated with adverse outcomes in patients with preserved ejection fraction after transcatheter aortic valve implantation. EUROPEAN HEART JOURNAL. IMAGING METHODS AND PRACTICE 2024; 2:qyae048. [PMID: 39045467 PMCID: PMC11195716 DOI: 10.1093/ehjimp/qyae048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 05/05/2024] [Indexed: 07/25/2024]
Abstract
Aims Cardiac power output (CPO) measures cardiac performance, and its prognostic significance in heart failure with preserved ejection fraction (EF) has been previously reported. However, the effectiveness of CPO in risk stratification of patients with valvular heart disease and post-operative valvular disease has not been reported. We aimed to determine the association between CPO and clinical outcomes in patients with preserved left ventricular (LV) EF after transcatheter aortic valve implantation (TAVI). Methods and results This retrospective observational study included 1047 consecutive patients with severe aortic stenosis after TAVI. All patients were followed up for all-cause mortality and hospitalization for HF. CPO was calculated as 0.222 × cardiac output × mean blood pressure (BP)/LV mass, where 0.222 was the conversion constant to W/100 g of the LV myocardium. CPO was assessed using transthoracic echocardiography at discharge after TAVI. Of the 1047 patients, 253 were excluded following the exclusion criteria, including those with low LVEF, and 794 patients (84.0 [80.0-88.0] years; 35.8% male) were included in this study. During a median follow-up period of 684 (237-1114) days, the composite endpoint occurred in 196 patients. A dose-dependent association was observed between the CPO levels and all-cause mortality. Patients in the lowest CPO tertile had significantly lower event-free survival rates (log-rank test, P = 0.043). Multivariate Cox regression analysis showed that CPO was independently associated with adverse outcomes (hazard ratio = 0.561, P = 0.020). CPO provided an incremental prognostic effect in the model based on clinical and echocardiographic markers (P = 0.034). Conclusion CPO is independently and incrementally associated with adverse outcomes in patients with preserved LVEF following TAVI.

Prognostic Value of Electrocardiographic Left Ventricular Hypertrophy After Transcatheter Aortic Valve Implantation: Insights from the OCEAN-TAVI Registry. Am J Cardiol 2023; 204:130-139.

Abstract
Electrocardiogram (ECG) left ventricular hypertrophy (LVH) is associated with the prognosis of patients with aortic stenosis. However, the impact of the presence or absence of ECG-LVH on the clinical outcomes after transcatheter aortic valve implantation (TAVI) is limited. This study aimed to assess the prognostic value of ECG-LVH among patients with aortic stenosis treated by TAVI. A total of 1,667 patients who underwent TAVI were prospectively enrolled into the OCEAN-TAVI (Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation) registry. A total of 1,446 patients (mean age 84 years; 29.9% men) were analyzed. The Sokolow-Lyon index was used to determine the presence of ECG-LVH. LVH was also assessed using transthoracic echocardiography (TTE). We investigated the association between ECG-LVH and all-cause and cardiovascular mortality. This study identified ECG-LVH and TTE-LVH in 743 (51.5%) and 1,242 patients (86.0%), respectively. The Kaplan-Meier analysis revealed that all-cause mortality was significantly higher among patients without ECG-LVH than among those with ECG-LVH (log-rank p <0.001). In the multivariable analysis, the absence of ECG-LVH was independently associated with all-cause mortality (hazard ratio 1.98, 95% confidence interval 1.39 to 2.82, p <0.001), regardless of the presence or absence of TTE-LVH. Furthermore, the presence of TTE-LVH with the absence of ECG-LVH was observed in 575 patients (40%), which was associated with cardiovascular mortality (hazard ratio 2.84, 95% confidence interval 1.56 to 5.17, p <0.001). In conclusion, the absence of ECG-LVH was independently associated with an increased risk of all-cause mortality after TAVI. Risk stratification using both ECG-LVH and TTE-LVH is a useful predictor of adverse clinical outcomes after TAVI.

STRUCTURAL HEART : THE JOURNAL OF THE HEART TEAM 2022; 6:100089.

Abstract
Degenerative calcific aortic stenosis (AS) is the most common valvular heart disease and often co-exists with left ventricular (LV) systolic dysfunction at the time of diagnosis. Impaired LV systolic function has been associated with worse outcomes in the setting of AS, even after successful aortic valve replacement (AVR). Myocyte apoptosis and myocardial fibrosis are the 2 key mechanisms responsible for the transition from the initial adaptation phase of LV hypertrophy to the phase of heart failure with reduced ejection fraction. Novel advanced imaging methods, based on echocardiography and cardiac magnetic resonance imaging, can detect LV dysfunction and remodeling at an early and reversible stage, with important implications for the optimal timing of AVR especially in patients with asymptomatic severe AS. Furthermore, the advent of transcatheter AVR as a first-line treatment for AS with excellent procedural outcomes, and evidence that even moderate AS portends worse prognosis in heart failure with reduced ejection fraction patients, has raised the question of early valve intervention in this patient population. With this review, we describe the pathophysiology and outcomes of LV systolic dysfunction in the setting of AS, present imaging predictors of LV recovery after AVR, and discuss future directions in the treatment of AS extending beyond the traditional indications defined in the current guidelines.

Abstract
Background Various ECG criteria for left ventricular hypertrophy (LVH) have been proposed, but their association with clinical outcomes in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement is unknown. We investigated the prevalence of ECG LVH according to different criteria and its prognostic impact on clinical outcomes after transcatheter aortic valve replacement. Methods and Results In this prospective observational cohort, we evaluated 700 patients who underwent transcatheter aortic valve replacement between March 2010 and December 2019. Baseline preprocedural LVH was defined by 3 ECG criteria—Sokolow‐Lyon, Romhilt‐Estes, and Cornell voltage criteria. The primary outcome was major adverse cardiac or cerebrovascular event (MACCE; composite of death, myocardial infarction, stroke, or rehospitalization from cardiovascular cause); the key secondary outcome was all‐cause and cardiovascular mortality. Among 596 eligible patients, the prevalence of LVH was determined as 56.3% by Sokolow‐Lyon, 31.1% by Romhilt‐Estes, and 48.1% by Cornell criteria. Regardless of the criteria, patients with ECG LVH had more severe aortic stenosis hemodynamics and higher left ventricular mass index. After multivariate adjustment, the presence of LVH by the Cornell criteria was significantly associated with lower risks of MACCE (adjusted hazard ratio [HR], 0.68; 95% CI, 0.51–0.91; P=0.009), all‐cause mortality (adjusted HR, 0.55; 95% CI, 0.34–0.90 [P=0.017]), and cardiovascular mortality (adjusted HR, 0.40; 95% CI, 0.20–0.79 [P=0.008]). However, this association was absent with the Sokolow‐Lyon and Romhilt‐Estes criteria. Conclusions ECG LVH by Cornell criteria only was significantly associated with lower risks of MACCE and all‐cause or cardiovascular mortality.

[PMID: 33768590 DOI: 10.1111/jocs.15515] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 03/13/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE This systematic review and meta-analysis aimed to evaluate whether the absence of electrocardiographic (ECG) left ventricular hypertrophy (LVH) was associated with poor outcome in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS We performed systematic review search on PubMed, Embase, and Scopus up until January 22, 2021. The key exposure was the absence of ECG LVH, defined as the absence of LVH by electrocardiographic criteria. The outcome of interest was composite poor outcome, which is a composite of mortality and/or rehospitalization after TAVR. The effect estimate was reported as hazard ratio (HR). In addition, we generate sensitivity and specificity, positive and negative likelihood ratio (PLR and NLR), diagnostic odds ratio (DOR), and area under curve (AUC). RESULTS There are four studies comprising of 827 patients included in this systematic review and meta-analysis. The prevalence of poor outcome in this pooled analysis was 30%. The absence of ECG LVH was associated with increased poor outcome in patients undergoing TAVR (HR: 1.86, [1.34, 2.57], p < .001; I2 : 0%). Absence of ECG LVH was associated with a sensitivity of 0.75 [0.64, 0.83], specificity of 0.42 [0.30, 0.55], PLR of 1.3 [1.1, 1.5], NLR of 0.60 [0.45, 0.80], DOR 2 [1, 5], and AUC of 0.66 [0.62, 0.70]. Fagan's nomogram indicates in a 22% prevalence of poor outcome in the included studies, the absence of ECG LVH and ECG LVH was associated with 27% and 15% posttest probability for poor outcome, respectively. CONCLUSION Absence of ECG LVH was associated with poor outcome in patients undergoing TAVR.
