Abstract
OBJECTIVE The aim of this study was to investigate the proportion of elevated left ventricular end-diastolic pressure (LVEDP) as an indicator of diastolic function after transcatheter aortic valve replacement (TAVR) and its implication in predicting long-term mortality. METHODS We analyzed retrospectively collected data on 3328 patients with severe aortic stenosis undergoing TAVR in our institution between July 2009 and June 2021. Patients were stratified into two groups based on invasive post-procedural LVEDP measurements: normal (<15 mmHg) vs. elevated (≥15 mmHg) LVEDP. RESULTS Mean age of the patients was 81.6 years, and 53.3% were female. Elevated post-procedural LVEDP was identified in 2408 (72.3%) patients. The 5-year mortality rates were higher in the group with elevated LVEDP compared with the group with normal LVEDP (27.4% vs. 8.3%, p = 0.01; hazard ratio [HR] 1.22, 95% CI 1.05-1.41). A multivariate model revealed the following independent predictors of mortality after TAVR: post-procedural elevated LVEDP (HR 1.24, 95% CI 1.01-1.53), pre-procedural significant tricuspid regurgitation (HR 1.24, 95% CI 1.02-1.52) and pulmonary hypertension (PH) (HR 1.53, 95% CI 1.26-1.86). In the present study, a significant paravalvular leak after TAVR was not associated with higher mortality (HR 1.45, 95% CI-0.95-2.19, p = 0.75). CONCLUSION Elevated post-procedural LVEDP in patients who undergo TAVR is an independent predictor of all-cause mortality. Furthermore, PH and tricuspid regurgitation were also identified as predictors of mortality. These data confirm that diastolic dysfunction is an important predictor of mortality in TAVR and should be considered to guide procedure timing, favoring an early interventional approach and management in aortic stenosis patients.

Abstract
BACKGROUND Non-invasive assessment of elevated left ventricular end-diastolic pressure (LVEDP) and pulmonary artery wedge pressure (PAWP) in patients with heart diseases is challenging. Lung ultrasonography (LUS) is a promising modality for predicting LVEDP and PAWP. METHODS Fifty-seven stable ambulatory patients who underwent right and left heart catheterization were included. Following the procedures, LUS was performed in twenty-eight ultrasonographic zones, and the correlation between five different LUS derived B-line scores with LVEDP and PAWP was examined. RESULTS The B-line index correlated with LVEDP and PAWP, with coefficients of 0.45 (p = 0.006) and 0.30 (p = 0.03), respectively. B-line index showed an AUC of 0.76 for identifying LVEDP > 15 mmHg (p = 0.01) and an AUC of 0.73 for identifying PAWP > 15 mmHg (p = 0.008). Overall, scores performances were similar in predicting LVEDP or PAWP > 15 mmHg. A B-line index ≥ 28 was significantly associated with LVEDP > 15 mmHg (OR: 9.97) and PAWP > 15 mmHg (OR: 6.61), adjusted for age and indication for heart catheterization. CONCLUSIONS LUS derived B-line scores are moderately correlated with PAWP and LVEDP in patients with heart diseases. A B-line index ≥ 28 can be used to predict elevated LVEDP and PAWP with high specificity.

Abstract
BACKGROUND Cardiac output (CO) is almost normal in children born without a functional right ventricle (RV), and a Fontan repair, so why is RV dysfunction such a clinical problem? We tested the hypotheses that increased pulmonary vascular resistance (PVR) is the dominant factor and volume expansion by any means is of limited benefit. METHODS We removed the RV from a previously used MATLAB model and altered vascular volume, venous compliance (Cv), PVR, and measures of left ventricular (LV) systolic and diastolic function. CO and regional vascular pressures were the primary outcome measures. RESULTS RV removal decreased CO by 25%, and raised mean systemic filling pressure (MSFP). A 10 mL/kg increase in stressed volume only moderately increased CO with or without the RV. Decreasing systemic Cv increased CO but also markedly increased pulmonary venous pressure. With no RV, increasing PVR had the greatest effect on CO. Increasing LV function had little benefit. CONCLUSIONS Model data indicate that increasing PVR dominates the decrease in CO in Fontan physiology. Increasing stressed volume by any means only moderately increased CO and increasing LV function had little effect. Decreasing systemic Cv unexpectedly markedly increased pulmonary venous pressures even with the RV intact.

Abstract
OBJECTIVE To investigate whether left atrial (LA) volume and left ventricular filling pressure (LVFP) assessed by cardiovascular magnetic resonance (CMR) change during adenosine delivered myocardial hyperaemia as part of a first-pass stress perfusion study. METHODS AND RESULTS We enrolled 33 patients who had stress CMR. These patients had a baseline four-chamber cine and stress four-chamber cine, which was done at peak myocardial hyperaemic state after administering adenosine. The left and right atria were segmented in the end ventricular diastolic and systolic phases. Short-axis cine stack was segmented for ventricular functional assessment. At peak hyperaemic state, left atrial end ventricular systolic volume just before mitral valve opening increased significantly from baseline in all (91 ± 35ml vs. 81 ± 33ml, P = 0.0002), in males only (99 ± 35ml vs. 88 ± 33ml, P = 0.002) and females only (70 ± 26ml vs. 62 ± 22ml, P = 0.02). The right atrial end ventricular systolic volume increased less significantly from baseline (68 ± 21ml vs. 63 ± 20ml, P = 0.0448). CMR-derived LVFP (equivalent to pulmonary capillary wedge pressure) increased significantly at the peak hyperaemic state in all (15.1 ± 2.9mmHg vs. 14.4 ± 2.8mmHg, P = 0.0002), females only (12.9 ± 2.1mmHg vs. 12.3 ± 1.9mmHg, P = 0.029) and males only (15.9 ± 2.8mmHg vs. 15.2 ± 2.7mmHg, P = 0.002) cohorts. CONCLUSION Left atrial volume assessment by CMR can measure acute and dynamic changes in preloading conditions on the left ventricle. During adenosine administered first-pass perfusion CMR, left atrial volume and LVFP rise significantly.

Abstract
BACKGROUND In recent years, heart failure with preserved ejection fraction (HFpEF) has received increasing clinical attention. To investigate the diagnostic value of diastolic function parameters derived from planar gated blood-pool imaging (MUGA) for detecting HFpEF in coronary atherosclerotic heart disease (coronary artery disease, CAD) patients. METHODS Ninety-seven CAD patients with left ventricular ejection fraction ≥ 50% were included in the study. Based on the left ventricular end-diastolic pressure (LVEDP), the patients were divided into the HFpEF group (LVEDP ≥ 16 mmHg, 47 cases) and the normal LV diastolic function group (LVEDP < 16 mmHg, 50 cases). Diastolic function parameters obtained by planar MUGA include peak filling rate (PFR), filling fraction during the first third of diastole (1/3FF), filling rate during the first third of diastole (1/3FR), mean filling rate during diastole (MFR), and peak filling time (TPF). Echocardiographic parameters include left atrial volume index (LAVI), peak tricuspid regurgitation velocity (peak TR velocity), transmitral diastolic early peak inflow velocity (E), average early diastolic velocities of mitral annulars (average e'), average E/e' ratio. The diastolic function parameters obtained by planar MUGA were compared with those obtained by echocardiography to explore the clinical value of planar MUGA for detecting HFpEF. RESULTS The Receiver-operating characteristic curve analysis of diastolic function parameters obtained from planar MUGA and echocardiography to detect HFpEF showed that: among the parameters examined by planar MUGA, the area under the curve (AUC) of PFR, 1/3FF, 1/3FR, MFR and TPF were 0.827, 0.662, 0.653, 0.663 and 0.809, respectively. Among the echocardiographic parameters, the AUCs for average e', average E/e' ratio, peak TR velocity, and LAVI values were 0.747, 0.706, 0.735, and 0.633. The combination of PFR and TPF showed an AUC of 0.856. PFR combined with TPF value demonstrated better predictive value than average e' (Z = 2.020, P = 0.043). CONCLUSION Diastolic function parameters obtained by planar MUGA can be used to diagnose HFpEF in CAD patients. PFR combined with TPF was superior to the parameters obtained by echocardiography and showed good sensitivity and predictive power for detecting HFpEF.

Abstract
Assessment of left ventricular filling pressure (LVFP) is crucial in patients with ST-segment elevation myocardial infarction (STEMI). Since current guideline recommended echocardiographic parameters have limited value, more comprehensive assessment methods are required in this patient subset.In this study, we aimed to investigate the clinical utility of left atrial reservoir strain (LARS) imaging in patients treated with primary percutaneous coronary intervention (pPCI). Patients who underwent successful pPCI were included. Left ventricular end-diastolic pressure (LVEDP) was measured invasively following pPCI. Left atrial strain imaging was performed following pPCI within 24 h of pPCI. Normal LARS value was accepted as above 23%. We prospectively enrolled 69 patients; there were 18 patients with LARS below 23% who were included into group 1 and rest of the study population included into group 2. There was no significant difference between groups in terms of comorbidities.Troponin and pro-BNP levels were significantly higher in group 1 (p: 0.036 and 0.047 respectively). Left atrial volume and tricuspid regurgitation velocity were similar between groups (p: 0.416 and p: 0.351 respectively). Septal tissue velocity was higher (p: 0.001) and Septal E/e' ratio was lower (p: 0.004) in group 2. Left ventricular (LV) global longitudinal strain value was higher in group 1 which is consistent with observed lower ejection (LVEF) fraction in group 1 (p: 0.001 for LV strain and p: 0.001 for LVEF). Estimated mean LVFP was also higher in group 1 (p: 0.003).Correlation analyses revealed moderate correlation between LARS and LVEDP (r: - 0.300). Our results indicate that left atrial strain imaging is a promising tool for the assessment of left atrial pressure in patients with STEMI.

Abstract
There are cross-sectional and longitudinal imaging studies using echocardiography and cardiac magnetic resonance in healthy adult subjects which have demonstrated associations of left ventricular (LV) structure and pump function with age. There are also cross-sectional data regarding the relationships of age with invasively measured left heart chamber pressures. Increasing age is associated with decreases in LV end-diastolic volume (LVEDV), end-systolic volume (LVESV), end-diastolic length (LVEDL), stroke volume (SV) and cardiac output (CO), and increases in relative wall thickness (RWT), LV mass/LVEDV ratio (LVMVR) and ejection fraction (LVEF). Older age is not accompanied by a change in mean left atrial (LA) pressure, but there is both direct and indirect evidence which suggests that LV end-diastolic pressure (LVEDP) increases with age. LVEDV remains lower in older than younger subjects during fluid infusion and the resulting increases in LA pressure. The combination of an increase in LVEF with reductions of both SV and CO demonstrates an age-related increase in divergence between LVEF and LV pump function. A lower LVEDV in older compared to younger subjects can be characterized as an aging-related decrease in LV capacity, with the higher LVEDP in older subjects also indicating a reduction of preload reserve.

Abstract
BACKGROUND AND OBJECTIVE Coronary artery disease (CAD) and heart failure are the most common cardiovascular diseases. Non-invasive diagnostic testing for CAD requires radiation, heart rate acceleration, and imaging infrastructure. Early detection of left ventricular dysfunction is critical in heart failure management, the best measure of which is an elevated left ventricular end-diastolic pressure (LVEDP) that can only be measured using invasive cardiac catheterization. There exists a need for non-invasive, safe, and fast diagnostic testing for CAD and elevated LVEDP. This research employs nonlinear dynamics to assess for significant CAD and elevated LVEDP using non-invasively acquired photoplethysmographic (PPG) and three-dimensional orthogonal voltage gradient (OVG) signals. PPG (variations of the blood volume perfusing the tissue) and OVG (mechano-electrical activity of the heart) signals represent the dynamics of the cardiovascular system. METHODS PPG and OVG were simultaneously acquired from two cohorts, (i) symptomatic subjects that underwent invasive cardiac catheterization, the gold standard test (408 CAD positive with stenosis≥ 70% and 186 with LVEDP≥ 20 mmHg) and (ii) asymptomatic healthy controls (676). A set of Poincaré-based synchrony features were developed to characterize the interactions between the OVG and PPG signals. The extracted features were employed to train machine learning models for CAD and LVEDP. Five-fold cross-validation was used and the best model was selected based on the average area under the receiver operating characteristic curve (AUC) across 100 runs, then assessed using a hold-out test set. RESULTS The Elastic Net model developed on the synchrony features can effectively classify CAD positive subjects from healthy controls with an average validation AUC=0.90±0.03 and an AUC= 0.89 on the test set. The developed model for LVEDP can discriminate subjects with elevated LVEDP from healthy controls with an average validation AUC=0.89±0.03 and an AUC=0.89 on the test set. The feature contributions results showed that the selection of a proper registration point for Poincaré analysis is essential for the development of predictive models for different disease targets. CONCLUSIONS Nonlinear features from simultaneously-acquired signals used as inputs to machine learning can assess CAD and LVEDP safely and accurately with an easy-to-use, portable device, utilized at the point-of-care without radiation, contrast, or patient preparation.

Abstract
Aims The clinical reliability of echocardiographic surrogate markers of left ventricular filling pressures (LVFPs) across different cardiovascular pathologies remains unanswered. The main objective was to evaluate the evidence of how effectively different echocardiographic indices estimate true LVFP. Methods and results Design: this is a systematic review and meta‐analysis. Data source: Scopus, PubMed and Embase. Eligibility criteria for selecting studies were those that used echocardiography to predict or estimate pulmonary capillary wedge pressure or left ventricular end‐diastolic pressures. Twenty‐seven studies met criteria. Only eight studies (30%) reported both correlation coefficient and bias between non‐invasive and invasively measured LVFPs. The majority of studies (74%) recorded invasive pulmonary capillary wedge pressure as a surrogate for left ventricular end‐diastolic pressures. The pooled correlation coefficient overall was r = 0.69 [95% confidence interval (CI) 0.63–0.75, P < 0.01]. Evaluation by cohort demonstrated varying association: heart failure with preserved ejection fraction (11 studies, n = 575, r = 0.59, 95% CI 0.53–0.64) and heart failure with reduced ejection fraction (8 studies, n = 381, r = 0.67, 95% CI 0.61–0.72). Conclusions Echocardiographic indices show moderate pooled association to invasively measured LVFP; however, this varies widely with disease state. In heart failure with preserved ejection fraction, no single echocardiography‐based metric offers a reliable estimate. In heart failure with reduced ejection fraction, mitral inflow‐derived indices (E/e′, E/A, E/Vp, and EDcT) have reasonable clinical applicability. While an integrated approach of several echocardiographic metrics provides the most promise for estimating LVFP reliably, such strategies need further validation in larger, patient‐specific studies.

Abstract
PURPOSE Cardiac dysfunction can occur as a sequela of a state of prolonged pressure overload and postischemic injury. Flavonoids such as quercetin may be protective against cardiovascular disease. This study aimed to systematically assess the effects of quercetin on cardiac function in pressure overload and postischemia-reperfusion injury in rodents. METHODS A systematic search of the literature up to May 2020 was conducted in PubMed, Ovid Medline, EBSCOhost, Scopus, and the Cochrane Library to identify relevant published studies on quercetin and cardiac function using standardized criteria. Meta-analyses were performed on animal studies of pressure overload and ischemia-reperfusion (I/R) injury. RESULTS The effects of quercetin on cardiac function in both models were qualitatively reported in 14 studies. The effects of quercetin in four pressure-overload model studies involving 73 rodents and eight I/R-injury model studies involving 120 rodents were quantitatively assessed by meta-analysis. Quercetin improved the overall cardiac function in both pressure overload (n = 4 studies, n = 73 rodents; SMD = - 1.50; 95% CI: - 2.66 to - 0.33; P < 0.05; I2 = 74.05%) and I/R injury (n = 8 studies, n = 120 rodents; SMD = - 1.81; 95% CI: - 3.05 to - 0.56; P < 0.01; I2 = 84.93%) models. The improvement was associated with amelioration in cardiac structure in the pressure-overload model and both systolic and diastolic functioning in the I/R-injury model. CONCLUSION The present meta-analysis suggested that quercetin has beneficial effects for improving cardiac left ventricular dysfunction in both pressure-overload and I/R-injury models.

Abstract
Left ventricular end-diastolic pressure (LVEDP) is an independent predictor for prognosis in ST-elevation myocardial infarction (STEMI) patients. We aimed to investigate the relationship of admission LVEDP measured after a successful primary percutaneous coronary intervention (pPCI) with scintigraphic infarct size (IS) and global longitudinal strain (GLS), a strong predictor of IS, in STEMI patients. A total of 62 consecutive patients with STEMI were enrolled in the study. LVEDP measurements were performed after pPCI in patients who had TIMI-3 flow. Echocardiography was performed 24 h after pPCI and repeated 3 months later. GLS was calculated as an average peak strain from the 3 apical projections. IS was evaluated at the third month by technetium 99m sestamibi. The mean age was 56 ± 8 years in the study population. The mean LVEDP was found 19.4 ± 4.4 mmHg. Median IS was 4% (0-11.7 IQR).The mean GLS at the 24th hour and the third month were found to be - 15.4 ± 2.8 and - 16.7 ± 2.5 respectively. There was a moderate negative correlation between LVEDP and GLS (24th-hour p < 0.001 r = - 0.485 and third-month p < 0.001 r = - 0.489). LVEDP had a moderate positive correlation with scintigraphic IS (p < 0.001 r = 0.545). In the multivariable model, we found that LVEDP was significantly associated with scintigraphic IS (β coefficient = 0.570, p = 0.008) but was not associated with the 24th hour (β coefficient = 0.092, p = 0.171) and third month GLS (β coefficient = 0.037, p = 0.531). This study demonstrated that there was a statistically significant relationship between LVEDP and scintigraphic IS, and IS was increased with high LVEDP values. However, there was not a relationship between LVEDP and GLS.

Abstract
Measurement of pulmonary venous flow (PVF) parameters can be used to estimate left ventricular end-diastolic pressure (LVEDP) on transthoracic echocardiography. Despite that, 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) algorithm gave a secondary role to PVF to assess left ventricular filling pressure. We aimed to test correlations between several PVF parameters, including novel measurements, with LVEDP and to analyze whether PVF parameters have an incremental usefulness over ASE/EACVI algorithm to estimate LVEDP. Seventy-two patients that underwent left and right cardiac catheterization for assessment of heart failure or pulmonary hypertension were enrolled. All patients had a detailed echocardiographic study immediately before catheterization. Patients were categorized into those with an LVEDP < 15 mmHg vs. LVEDP ≥ 15 mmHg to analyze data. Patients with an elevated LVEDP had significantly lower peak S/D velocity ratio, S wave deceleration time, D wave acceleration time and D wave deceleration time (DWDT), as well as higher D wave acceleration rate (DWAR), but only peak S/D velocity ratio (β = - 0.28, p = 0.01), DWDT (β = - 0.33, p = 0.001) and DWAR (β = 0.23, p = 0.03) were independent predictors for an elevated LVEDP. ASE/EACVI algorithm had a sensitivity of 71% and specificity of 74% to predict an elevated LVEDP. When PVF parameters were adjusted for ASE/EACVI algorithm; DWDT and DWAR remained as independent predictors. Sensitivity and specificity of ASE/EACVI algorithm increased to 79% and 96%, respectively, if either DWDT or DWAR was also suggestive of an elevated LVEDP. DWDT and DWAR have incremental usefulness over existing algorithm to determine LVEDP.

Abstract
AIMS To study the correlation between intra-procedural left ventricular end-diastolic pressure (LVEDP) and the development of contrast-induced acute kidney injury (CI-AKI) in patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS A single center retrospective observational study compared clinical and hemodynamic characteristics of patients who developed post-PCI CI-AKI with those did not. CI-AKI was defined as an absolute increase in serum creatinine ≥0.5 mg/dl or an increase ≥25% from baseline 48-72 h after the administration of contrast medium. Among 1301 consecutive patients who underwent PCI, 125 patients (9.6%) developed CI-AKI. The CI-AKI group had a higher average LVEDP (18.4 ± 8.7 vs 14.4 ± 6.6 mm Hg; p < .0001) and higher prevalence of elevated LVEDP (≥20 mm Hg) than those without CI-AKI (47.2% vs 23.3%, p < .0001). After adjustments, elevated LVEDP remained independently associated with CI-AKI (OR 2.21; 95% CI 1.40-3.50). LVEDP predicted the development of CI-AKI with a receiver operating characteristic area under curve (AUC) of 0.64. The association between elevated LVEDP and the risk of CI-AKI was stronger in patients with reduced ejection fraction (EF ≤ 40%) (OR = 4.08; 95% CI: 1.68-9.91) than those with preserved EF (OR = 1.69; 95% CI: 0.94-3.04) (p value for interaction = .0003). Patients who had LVEDP ≥ 20 mm Hg and LVEF ≤ 40% had a post-PCI incidence rate of developing CI-AKI of 36.5%. CONCLUSIONS Elevated intra-procedural LVEDP (≥20 mm Hg) is independently associated with increased risk of CI-AKI for patients undergoing cardiac catheterization and PCI, especially in the setting of reduced LVEF (≤40%).

Abstract
Assessment of left ventricular diastolic function by transthoracic Doppler echocardiography is based on a multiparametric approach which includes the spectral tissue Doppler-derived E/e'. Recently, a new Doppler index, E/(e'xs'), which combines E/e' with a spectral tissue Doppler-derived marker of systolic function, s', has been proposed in noninvasive assessment of left ventricular myocardial dysfunction. Current literature provides evidence that E/(e'xs') has good correlation with NT proBNP levels and invasive left ventricular end-diastolic pressure, both used as markers of left ventricular myocardial dysfunction, irrespective of left ventricular ejection fraction and wall motion abnormalities. More specifically, E/(e'xs') has good diagnostic accuracy in patients with intermediate values for E/e' (8 to 15). Average E/(e'xs')>1.6 is reported to predict invasive left ventricular end-diastolic pressure>15mmHg with a sensitivity of 86% and a specificity of 85%. Current literature provides evidence that E/(e'xs') could offer better prognostic information than E/e' in patients with systolic heart failure and heart failure with normal ejection fraction, as well as in patients with asymptomatic heart disease. A few clinical studies also suggest that E/(e'xs') could predict recurrence of atrial fibrillation after cardioversion and left ventricular remodeling after acute myocardial infarction. Further experimental and clinical investigation is critically needed to determine the role of this under-recognized tissue Doppler index in noninvasive assessment of cardiovascular diseases, in particular heart failure with normal ejection fraction.

Abstract
OBJECTIVES Contrast-induced acute kidney injury (CI-AKI) is a serious complication in patients undergoing diagnostic cardiac angiography or percutaneous coronary intervention. We aimed to evaluate the preventive effects of left ventricular end-diastolic pressure (LVEDP)-guided hydration for the prevention of CI-AKI in patients with chronic kidney disease undergoing cardiac catheterization. METHODS This prospective randomized single-blind clinical trial enrolled 114 eligible patients with an estimated glomerular filtration rate (eGFR) of 15 < eGFR ≤ 60 mL/min/1.73 m2 [according to the level-modified Modification of Diet in Renal Disease formula (MDRD)] and stable ischemic heart disease undergoing coronary procedures. The patients were randomly allocated 1:1 into the LVEDP-guided hydration group (n = 57) or the standard hydration group (n = 57). CI-AKI was defined as a greater than 25% or greater than 0.5 mg/dL (44.2 mmol/L) increase in the serum creatinine concentration compared with the baseline value. Hydration with 0.9% sodium chloride at a rate of 1 mL/kg/h (0.5 mL/kg/h if left ventricular ejection fraction < 40%) within 12 h was given to all the patients in both groups before the procedure. In the LVEDP-guided group, the hydration infusion rate was adjusted according to the LVEDP level during and after the procedure. RESULTS The incidence of CI-AKI was 7.01% (4/57) in the LVEDP-guided group vs 3.84% (2/52) in the standard hydration group (summary odds ratio 0.53, 95% CI 0.093-3.022; P = 0.463). Major adverse cardiac events, hemodialysis, or related deaths occurred in neither of the groups during hospitalization or the 30-day follow-up. CONCLUSIONS In the present study, LVEDP-guided fluid administration, by comparison with standard hydration, failed to offer protection against the risk of CI-AKI in patients with renal insufficiency undergoing coronary angiography with or without percutaneous coronary intervention.

Abstract
BACKGROUND There is a rising incidence of contrast-induced nephropathy (CIN), which is defined as either a 25% relative increase or an absolute increase of 0.5 mg/dL (44.2 µmol/L) in the serum creatinine (Scr) level at 48-72 h after administration of iodinated contrast media (CM). We investigated the relationship between left ventricular end-diastolic pressure (LVEDP) and CIN in patients undergoing percutaneous coronary intervention (PCI). METHODS A total of 431 consecutive patients with coronary artery disease undergoing PCI were divided into four groups based on LVEDP quartile cut-off points. Enrolled patients were given continuous intravenous infusion of normal saline starting 4 h before PCI and lasting 24 h. At the end of hydration administration, 20 mg furosemide was slowly injected intravenously. Serum creatinine (Scr), creatinine clearance rate (Ccr), and glomerular filtration rate (GFR) were detected before and after PCI. RESULTS There were significant differences in the incidences of CIN in the four groups: 10.25% in the Q1 group, 5.55% in the Q2 group, 5.31% in the Q3 group, and 1.06% in the Q4 group (P < 0.05). With increasing LVEDP, the incidence of CIN decreased significantly (OR 0.581, 95% CI 0.367-0.920). Received operating characteristic curve analysis of the predictive value of LVEDP for CIN produced area under the curve values was 0.641, with a sensitivity of 74.1% and specificity of 48%. The optimal LVEDP cut-off for the occurrence of CIN was 14.5 mmHg. CONCLUSIONS LVEDP correlated inversely with CIN in patients undergoing PCI.

Abstract
Transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis is a less invasive alternative to surgical aortic valve replacement. Despite this, careful anesthetic management, especially strict control of blood pressure and fluid management, is necessary. During TAVI, normalization of left ventricular afterload due to aortic balloon valvuloplasty and prosthetic valve deployment is expected to result in rapid improvement of systolic function and consequent improvement in diastolic function. However, the early effect of TAVI on left ventricular diastolic function is less clear. We hypothesized that TAVI induces a rapid decrease in left ventricular end-diastolic pressure (LVEDP) after valve deployment. This retrospective observational study included 71 patients who had undergone TAVI using the transfemoral approach with a balloon-expandable valve under general anesthesia. Intraoperative LVEDP was measured using an intracardiac catheter. The severity of residual aortic regurgitation (AR) was assessed using the Sellers criteria. The mean (SD) LVEDP was 17.8 (5.3) mmHg just before TAVI and increased significantly to 27.3 (8.2) mmHg immediately after prosthetic valve deployment (p < 0.0001). The change in LVEDP was 8.7 (8.6) mmHg in patients with low residual AR (Sellers ≤1) and 11.0 (7.1) mmHg in those with high residual AR (Sellers ≥2); however, this difference was not significant. No correlation was found between the LVEDP change and intraoperative fluid balance. In conclusion, LVEDP increased significantly in the early period after valve deployment during TAVI, regardless of residual AR severity. It was suggested that the tolerability of fluid load could be reduced at that time.

Abstract
Background Elevated left ventricular end-diastolic pressure (LVEDP) has been reported to predict an increased mortality in patients with ST-segment elevation myocardial infarction. However, its prognostic value in patients with non-ST-segment elevation myocardial infarction (NSTEMI) remains unclear. Methods We performed a retrospective analysis of NSTEMI patients who underwent coronary angiography between January 2013 and June 2014. We excluded patients who did not undergo LVEDP measurements. Baseline and angiographic characteristics, in-hospital heart failure as well as in-hospital mortality were recorded. Results After exclusion, 367 patients were included in the final analysis. The median (interquartile range) LVEDP was 19 mm Hg (14 - 24 mm Hg). By receiver operating characteristic curve analysis, the optimal cutoff value for predicting in-hospital mortality was 22 mm Hg (area under the curve 0.80, sensitivity 80%, and specificity 71%). Of 367 patients, 109 patients (29.7%) had LVEDP > 22 mm Hg. Patients with LVEDP > 22 mm Hg had a greater number of comorbidities. There was no statistically significant difference in the rate of multi-vessel disease. Patients with LVEDP > 22 mm Hg had a significantly higher rate of in-hospital heart failure (22.0% vs. 13.2%, P = 0.03) and in-hospital mortality (3.7% vs. 0.4%, P = 0.03) than those with LVEDP ≤ 22 mm Hg. Conclusion Elevated LVEDP was significantly associated with a higher in-hospital mortality in patients with NSTEMI.

Regional wall motion abnormality at the lateral wall disturbs correlations between tissue Doppler E/e' ratios and left ventricular diastolic performance parameters measured by invasive methods. J Echocardiogr 2013; 11:138-46. [PMID: 24319341 DOI: 10.1007/s12574-013-0193-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [What about the content of this article?

Abstract
Background The impact of regional wall motion abnormality (RWMA) on the accuracy of heart failure with preserved ejection fraction (HFpEF) diagnosis using the E/e′ ratio, which is a non-invasive parameter of left ventricular diastolic performance, is unknown. The purpose of this study was to elucidate the impact of RWMA of the lateral wall (RWMAlat) on the correlation between E/e′ and invasive parameters of left ventricular diastolic performance. Methods Three hundred and eight consecutive patients undergoing tissue Doppler imaging and catheterization pressure examination were retrospectively analyzed. E/e′ was calculated as the ratio of early diastolic transmitral flow velocity to mitral annular velocity at the lateral wall. Invasive parameters including left ventricular end-diastolic pressure (LVEDP) and isovolumetric relaxation time constant (τ) were assessed based on the left ventricular pressure study. Correlation coefficients between E/e′ and these invasive parameters were analyzed and compared between cases with RWMAlat and without RWMA. Results LVEDP and τ correlated well with E/e′ for all 308 patients (r = 0.51 and r = 0.65, respectively). Sixty-two patients had RWMA; the remaining 246 did not have RWMAlat. We confirmed that the presence of RWMAlat weakens both the correlations between E/e′ and LVEDP (r = 0.574 vs. r = 0.381), and E/e′ and τ (r = 0.729 vs. r = 0.461). Conclusions Although E/e′ correlates well with parameters of left ventricular diastolic performance assessed by invasive methods, the presence of RWMAlat worsens this correlation. In cases with RWMAlat, careful assessment is required for HFpEF diagnosis because the diagnostic value of the E/e′ ratio could be decreased compared to patients without RWMAlat.
