Abstract
PURPOSE OF REVIEW The purpose of this review is to highlight the echo Doppler parameters that form the cornerstone for the evaluation of diastolic function as per the guideline documents of the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI). In addition, the individual Doppler-based parameters will be explored, with commentary on the rationale behind their use and the multi-parametric approach to the assessment of diastolic dysfunction (DD) using echocardiography. RECENT FINDINGS Previous guidelines for assessment of diastolic function are complex with modest diagnostic performance and significant inter-observer variability. The most recent guidelines have made the evaluation of DD more streamlined with excellent correlation with invasive measures of LV filling pressures. This is a review of the echo-derived Doppler parameters that are integral in the diagnosis and gradation of DD. A brief description of the physiological principles that govern changes in echocardiographic parameters during normal and abnormal diastolic function is also discussed for the appropriate diagnosis of DD using non-invasive Doppler echocardiography techniques.

The impact of cardiac loading on a novel metric of left ventricular diastolic function in healthy middle-aged adults: Systolic-diastolic coupling. Physiol Rep 2021; 9:e15129. [PMID: 34873864 PMCID: PMC8649710 DOI: 10.14814/phy2.15129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 11/24/2021] [Accepted: 11/14/2021] [Indexed: 11/24/2022] Open
Abstract
AIMS Left ventricular (LV) restoring forces are primed by ventricular deformation during systole and contribute to cardiac relaxation and early diastolic suction. Systolic-diastolic coupling, the relationship between systolic contraction and diastolic recoil, is a novel marker of restoring forces, but the effect of left atrial pressure (LAP) is unknown. We tested preliminary methods of systolic-diastolic coupling comparing mitral annular velocities versus excursion distances and hypothesized a recoil/contraction distance ratio would remain unaffected across varying LAP, providing a surrogate for quantifying LV restoring forces. METHODS AND RESULTS Healthy subjects (n = 61, age 52 ± 5 years) underwent manipulation of LAP with lower body negative pressure (LBNP) and rapid normal saline (NS) infusion. Pulmonary capillary wedge pressure (PCWP; pulmonary artery catheter) and tissue Doppler imaging of the mitral annulus were measured. Two models of systolic-diastolic coupling--early diastolic excursion (EDexc )/systolic contraction (Sexc ) distances and e'/systolic (s') velocities were compared. Velocity (e'/s') coupling ratios varied significantly (mean e'/s', slope = 0.022, p < 0.001) in relationship with PCWP (5-20 mmHg). Excursion (EDexc /Sexc ) coupling ratio did not vary in relationship with PCWP (EDexc /Sexc : slope = -0.001, p = 0.19). CONCLUSIONS Systolic-diastolic coupling using mitral annular distance ratios to standardize early diastolic recoil to systolic contraction was not significantly impacted by LAP, in contrast to coupling ratios using velocities. The pressure invariance of annular distance coupling ratios suggests this metric quantifies the efficiency of LV restoring forces by isolating systolic contributions to early diastolic restoring forces independent from changes in LAP.

Abstract
The mechanism of flow propagation during diastole in the left ventricle (LV) has been well described. Little is known about the associated waves propagating along the heart walls. These waves may have a mechanism similar to pulse wave propagation in arteries. The major goal of the study was to evaluate the effect of myocardial stiffness and preload on this wave transmission. Longitudinal late diastolic deformation and wave speed (Vp) of myocardial stretch in the anterior LV wall were measured using sonomicrometry in 16 pigs. Animals with normal and altered myocardial stiffness (acute myocardial infarction) were studied with and without preload alterations. Elastic modulus estimated from Vp (E VP; Moens-Korteweg equation) was compared to incremental elastic modulus obtained from exponential end-diastolic stress-strain relation (E SS). Myocardial distensibility and α- and β-coefficients of stress-strain relations were calculated. Vp was higher at reperfusion compared to baseline (2.6 ± 1.3 vs. 1.3 ± 0.4 m/s; p = 0.005) and best correlated with E SS (r2 = 0.80, p < 0.0001), β-coefficient (r2 = 0.78, p < 0.0001), distensibility (r2 = 0.47, p = 0.005), and wall thickness/diameter ratio (r2 = 0.42, p = 0.009). Elastic moduli (E VP and E SS) were strongly correlated (r2 = 0.83, p < 0.0001). Increasing preload increased Vp and E VP and decreased distensibility. At multivariate analysis, E SS, wall thickness, and end-diastolic and systolic LV pressures were independent predictors of Vp (r2 model = 0.83, p < 0.0001). In conclusion, the main determinants of wave propagation of longitudinal myocardial stretch were myocardial stiffness and LV geometry and pressure. This local wave speed could potentially be measured noninvasively by echocardiography.

Abstract
This report describes the use of echocardiographic measurements for the assessment of left ventricular diastolic function in two young patients with newly diagnosed hypertension. Measurements for the assessment of left ventricular relaxation and filling pressures included mitral inflow, Doppler tissue imaging (DTI), color M-mode propagation velocity slope, and the isovolumic relaxation time. The mitral inflow, propagation velocity, and isovolumic relaxation time measurements were all within normal limits; however, DTI measurements of the E′ velocity at the septal and lateral annulus were significantly reduced in both patients. Further visual inspection demonstrated discrete proximal septal wall thickening that is thought to be modulated by pressure loading (i.e., increased afterload due to hypertension) and ejection. These findings may represent a “transitional state” of early ventricular remodeling and organ failure in the development of hypertensive disease. In summary, DTI appears to be more sensitive compared to other markers in identifying abnormal relaxation in subclinical hypertensive disease and normal ejection fraction.

Abstract
PURPOSE OF REVIEW Nearly half of patients presenting with heart failure have a preserved left ventricular ejection fraction (LVEF), previously known as diastolic heart failure. The diagnosis requires fulfillment of three criteria: signs or symptoms of heart failure, presence of a normal LVEF, and evidence of diastolic dysfunction. Two of the criteria can be evaluated by echocardiography. This article reviews the echocardiographic approach to the patient with suspected heart failure with a normal left ventricular ejection fraction (HFNEF). RECENT FINDINGS Echocardiography is the primary modality for evaluating left ventricular (LV) systolic and diastolic function in heart failure patients. Measurements of LVEF from two-dimensional echocardiography can have significant variability despite the use of quantitative methods. The use of contrast agents and three-dimensional echocardiography can improve the accuracy. Newer modalities of tissue Doppler imaging and deformation imaging are challenging the concept that systolic function is preserved in HFNEF. Evaluation of diastolic function with echocardiography requires a comprehensive approach using multiple modalities to quantitate transmitral flow, pulmonary venous flow, mitral annular motion, myocardial deformation, and cardiac structure. The clinical applicability of parameters used for evaluating diastolic function and filling pressures is dependent on the LVEF, necessitating a unique approach in patients with suspected HFNEF. SUMMARY A comprehensive examination with knowledge of the potential limitations of echocardiography is required to accurately interpret LV systolic and diastolic function in patients with suspected HFNEF.

Abstract
Assessment of diastolic function should be a component of a comprehensive perioperative transesophageal echocardiographic examination. Abnormal diastolic function exists in >50% of patients presenting for cardiac and high-risk noncardiac surgery, and has been shown to be an independent predictor of adverse postoperative outcome. Normalcy of systolic function in 50% of patients with congestive heart failure implicates diastolic dysfunction as the probable etiology. Comprehensive evaluation of diastolic function requires the use of various, load-dependent Doppler techniques This is further complicated by the additional effects of dehydration and anesthetic drugs on myocardial relaxation and compliance as assessed by these Doppler measures. The availability of more sophisticated Doppler techniques, e.g., Doppler tissue imaging and flow propagation velocity, makes it possible to interrogate left ventricular diastolic function with greater precision, analyze specific stages of diastole, and to differentiate abnormalities of relaxation from compliance. Additionally, various Doppler-derived ratios can be used to estimate left ventricular filling pressures. The varying hemodynamic environment of the operating room mandates modification of the diagnostic algorithms used for ambulatory cardiac patients when left ventricular diastolic function is evaluated with transesophageal echocardiography in anesthetized surgical patients.

Abstract
Background—
During late ejection, myocardial relaxation causes systolic flow to decelerate and stop, and this phenomenon is coupled with the generation of a pressure gradient inside the left ventricle (LV). We hypothesized that the peak reverse ejection intraventricular pressure difference (REIVPD) between the LV apex and the outflow tract could be a useful method to improve the assessment of LV relaxation using Doppler echocardiography.
Methods and Results—
Three sets of animal experiments and 1 clinical study were designed. In 6 pigs, a close relationship between REIVPD and the intensity of the relaxation wave (
R
rm
=0.89) was demonstrated using wave intensity analysis of high-fidelity pressure-volume-velocity data. In 19 animals, REIVPD sensitively detected modifications of the lusotropic state and closely correlated with the time constant of LV relaxation (τ) within animals (
R
rm
=−0.93). Load-dependence analysis in 5 pigs showed that REIVPD remained stable up to values of 35% to 40% acute preload reduction. Clinical validation was tested in 50 patients (23 with normal systolic function) undergoing simultaneous Doppler echocardiography and high-fidelity LV pressure measurements on the same beat. REIVPD and tissue Doppler mitral annulus velocity (e′) were independently related to τ, but the REIVPD · e′ product correlated better with τ than either variable separately (bootstrap-corrected correlation coefficients:
R
=−0.84 versus −0.71, and −0.70, respectively,
P
<0.05). Area under the receiver operating characteristic curve to predict impaired relaxation (τ>50 ms) for e′ · REIVPD was 0.96 (95% confidence interval, 0.85 to 0.99).
Conclusions—
The Doppler-derived REIVPD provides a sensitive, reliable, reproducible, and relatively load-independent index of the rate of LV relaxation. Combined with tissue Doppler measurements of longitudinal function, this method improves noninvasive assessment of LV relaxation in the clinical setting.

Abstract
BACKGROUND Prior studies demonstrating the prognostic value of echocardiographic measures of diastolic function have been limited by sample size, have included only select clinical populations, and have not incorporated newer measures of diastolic function nor determined their independent prognostic value. The objective of this study is to determine the independent prognostic value of established and new echocardiographic parameters of diastolic function. METHODS We included 3,604 consecutive patients referred to 1 of 3 echocardiography laboratories over a 2-year period. We obtained measurements of mitral inflow velocities, pulmonary vein filling pattern, mitral annulus motion (e'), and propagation velocity (V(p)). The primary end point was 1-year all-cause mortality. RESULTS The mean age of the patients was 68 years, and 95% were male. There were 277 deaths during a mean follow-up of 248 ± 221 days. For patients with reduced left ventricular ejection fraction (LVEF), all measured parameters except for e' were associated with mortality (P < .05) on univariate analysis. For patients with preserved LVEF, the E-wave velocity was significantly associated with mortality (P < .05) on univariate analysis. The deceleration time/E-wave velocity ratio, V(p), and pulmonary vein filling pattern were borderline significant (P < .10). With multivariate analysis, only V(p) was associated with survival for both reduced (P = .02) and preserved LVEF groups (P = .01). CONCLUSION In a large, clinically diverse population, most measures of diastolic function were predictive of all-cause mortality without adjustment for patient characteristics. On multivariate analysis, only V(p) was independently associated with total mortality. This association with mortality may be related to factors other than diastolic function and warrants further investigation.

Abstract
Diastolic heart failure is increasing in prevalence. Although the pathophysiology is incompletely understood and current therapeutic strategies are limited, identification of diastolic dysfunction is important. We review the role of contemporary techniques with echocardiography and cardiac magnetic resonance imaging (CMRI) in the assessment of diastolic dysfunction. Cardiac catheterization is the criterion standard for demonstrating impaired relaxation and filling by making direct measurements; however, echocardiography has replaced it as the most clinically used tool. By evaluating mitral inflow pulsed-wave Doppler with and without the Valsalva maneuver, isovolumetric relaxation time, pulmonary venous flow Doppler, color M-mode velocity propagation, tissue Doppler imaging, and speckle tracking, echocardiography is considered an accurate method for diagnosis and grading diastolic dysfunction. Evaluation of diastolic function can also be performed by CMRI. Mitral valve inflow velocities, early deceleration time, and pulmonary vein flow velocities are diastolic parameters that can be measured by phase-contrast CMRI. Cardiac magnetic resonance imaging steady-state gradient echo can evaluate functional dimensions for time-volume curves; and myocardial tagging can assess ventricular diastolic "untwisting," which may be important for improved pathophysiologic understanding. Studies have compared echocardiography and CMRI for diagnosing diastolic dysfunction in small patient groups with similar results. Cardiac magnetic resonance imaging can now provide clinically relevant data regarding the underlying cause of diastolic dysfunction and offers promise to gain mechanistic insights for therapeutic strategy development and clinical trial planning.

Abstract
OBJECTIVES Aortic valve implantation through peripheral vascular access is an option for high-risk patients with severe aortic valve stenosis. The authors aimed to compare the acute effect of endovascular and surgical aortic valve procedures on left ventricular diastolic function. DESIGN A case-matched, nonrandomized study. SETTING A university hospital. PARTICIPANTS Patients with aortic stenosis. INTERVENTIONS B-natriuretic peptide was measured in 30 patients with a logistic EuroSCORE > or =20% undergoing endovascular aortic valve implantation. Patients were case matched (age, mitral flow propagation velocity, mitral annulus early diastolic velocity, and B-natriuretic peptide measurement) with 30 control patients undergoing surgical aortic valve replacement through sternotomy. Left ventricular diastole was evaluated initially and after valve procedures with echocardiography by mitral flow propagation velocity and mitral annulus early diastolic velocity. MEASUREMENTS AND MAIN RESULTS B-natriuretic peptide was similar preoperatively in the 2 groups (346 [188-438] v 367 [211-458] pg/mL) and higher (p = 0.006) in the surgical group postoperatively (389.5 [237-479] v 710.5 [389-822] pg/mL), with a postprocedural statistically significant increase only in the surgical group. Diastolic function was similar in the 2 groups preoperatively, improved postoperatively in the endovascular group, and worsened in the surgical group. CONCLUSIONS B-natriuretic peptide increased after surgical but not after endovascular aortic valve replacement. Furthermore, endovascular aortic valve implantation acutely improved left ventricular diastolic function as documented by increases in mitral flow propagation velocity and mitral annulus early diastolic velocity.

Abstract
Diastolic dysfunction has been linked to 2 epidemics: atrial fibrillation (AF) and heart failure. The presence and severity of diastolic dysfunction are associated with an increased risk for first AF and first heart failure in patients with sinus rhythm. Furthermore, the risk for heart failure is markedly increased once AF develops. The evaluation of diastolic function once AF has developed remains a clinical challenge. The conventional use of Doppler echocardiography for the assessment and grading of diastolic dysfunction relies heavily on evaluating the relation of ventricular and atrial flow characteristics. The mechanical impairment of the left atrium and the variable cycle lengths in AF render the evaluation of diastolic function difficult. A few Doppler echocardiographic methods have been proved clinically useful for the estimation of diastolic left ventricular filling pressures in AF, but these appear to be underutilized. Several innovative methods are emerging that promise to provide greater precision in diastolic function assessment, but their clinical utility in AF remains to be established. In conclusion, this review provides an up-to-date discussion of the evaluation of diastolic function assessment in AF and how it may be important in the clinical management of patients with AF.

Peak mitral annular velocity during early diastole and propagation velocity of early diastolic filling flow are not interchangeable as the parameters of left ventricular early diastolic function.

Abstract
The difference between peak mitral annular velocity during early diastole (Ea) and the propagation velocity of left ventricular (LV) early diastolic filling flow (Vp) obtained using Doppler imaging as LV relaxation parameters was not fully elucidated. Thus, this issue was investigated in 117 patients with suspected coronary artery disease. During cardiac catheterization, LV volumes, the LV relaxation time constant Tp, and inertia force of late systolic aortic flow were obtained. Ea significantly and closely correlated with Tp (r = -0.70, p <0.0001) and significantly but weakly correlated with LV ejection fraction (r = 0.37, p <0.0001) and inertia force (r = 0.34, p = 0.0002). Conversely, Vp significantly and closely correlated with both LV ejection fraction (r = 0.66, p <0.0001) and inertia force (r = 0.72, p <0.0001) and significantly but weakly correlated with Tp (r = - 0.35, p = 0.0001). In conclusion, Ea and Vp reflect different aspects of LV behavior from end-systole to early diastole. Ea can be used to index LV relaxation, whereas Vp might not be a proper parameter of LV intrinsic relaxation because it is significantly dependent on LV systolic function and LV chamber size at end-systole. Both parameters are not interchangeable as those of LV early diastolic function. Vp may be a noninvasive parameter of LV elastic recoil.

Abstract
INTRODUCTION Tissue Doppler imaging (TDI) and color M-mode (CMM) indices provide assessment of left ventricular (LV) relaxation when combined with pulse-wave Doppler (PWD)-derived transmitral inflow, allows for estimation of LV filling pressures. However, use of these indices in patients with LV systolic dysfunction (LVSD) has not been well characterized. METHODS AND RESULTS The study included 115 patients (age 58 +/- 11 years, 67% male) with LVSD (LV ejection fraction [LVEF] < 55%). Patients were grouped according to the diastolic LV filling pressure assessed by E/Em(septal) ratio as follows: 1) Normal (NFP), E/Em(septal) < 8; 2) Intermediate (IFP), E/Em(septal): 8-15; and 3) High (HFP), E/Em(septal) >15. Age-, gender-, and LVEF-adjusted analyses were performed. LV volumes and LVEF were significantly different between the groups (P < 0.01). PWD-derived E-wave velocity showed a significant stepwise increase across the three groups and the Em(septal) velocity demonstrated a stepwise decrease (P < 0.01 for both). CMM-derived diastolic intra-ventricular pressure gradient (IVPG) was significantly lower in the HFP compared to the other 2 groups (P < 0.01 for both); Vp was increased in the HFP compared to the other 2 groups (P < 0.01 for both), and Vp exhibited a U-shape relationship to LVEF. CONCLUSION In patients with LVSD, abnormal LV relaxation is uniformly observed regardless of LV filling pressure. PWD-derived E-wave velocity and the TDI-derived Em velocity are important measurements to identify elevated LV filling pressures. CMM-derived Vp and IVPG were of limited incremental value for the evaluation of diastolic function in patients with LVSD.

Abstract
OBJECTIVES We investigated whether a lack of inertia force of late systolic aortic flow and/or apical asynergy provoke early diastolic dysfunction in patients with coronary artery disease (CAD). BACKGROUND Left ventricular (LV) isolated diastolic dysfunction is a well-recognized cause of heart failure. METHODS We evaluated LV apical wall motion and obtained left ventricular ejection fraction (LVEF) by left ventriculography in 101 patients who underwent cardiac catheterization to assess CAD. We also computed the LV relaxation time constant (Tp) and the inertia force of late systolic aortic flow from the LV pressure (P)-first derivative of left ventricular pressure (dP/dt) relation. Using color Doppler echocardiography, we measured the propagation velocity of LV early diastolic filling flow (Vp). Patients with LVEF > or =50% (preserved systolic function [PSF], n = 83) were divided into 2 subgroups: patients with inertia force (n = 53) and without inertia force (n = 30). No patient with systolic dysfunction (SDF) (LVEF <50%) had inertia force (n = 18). RESULTS The Tp was significantly longer in patients with SDF (85.7 +/- 21.0 ms) and with PSF without inertia force (81.1 +/- 23.6 ms) than in those with PSF with inertia force (66.3 +/- 12.8 ms) (p< 0.001). The Vp was significantly less in the former 2 groups than in the last group. In patients with PSF, LV apical wall motion abnormality was less frequently observed in those with inertia force than in those without (p < 0.0001). CONCLUSIONS An absence of inertia force in patients with PSF is one of the causes of isolated diastolic dysfunction in patients with CAD. Normal LV apical wall motion is substantial enough to give inertia to late systolic aortic flow.

Abstract
Fabry disease is an X-linked genetic disorder characterized by progressive intracellular accumulation of neutral glycosphingolipids. Cardiac involvement is frequent and left ventricular (LV) diastolic dysfunction is present in most of the affected subjects. Pulsed-wave tissue Doppler echocardiography (PW-TDE) and color M-mode are new Doppler methods for LV diastolic function evaluation. Their role in the assessment of Fabry disease-related cardiomyopathy remains to be established. In this study we aimed to determine the utility of PW-TDE and color M-mode-derived parameters in the assessment of LV diastolic function in patients with Fabry disease. Eighty-one echocardiographic examinations performed in 35 patients affected by Fabry disease were retrospectively analyzed. Early diastolic lateral mitral annular velocity (E(m)) determined by PW-TDE and color M-mode flow propagation velocity (V(p)) were measured and compared to LV filling patterns obtained using standard Doppler indexes. The receiver operating characteristics (ROC) curves method was used to determine the summary measure of relative accuracy for E(m) and V(p). A comparison of ROC curves showed a significant difference for areas under the curve in favor of E(m) (P < 0.001). Pseudonormal filling pattern, higher LV mass index, higher relative wall thickness, larger left atrial diameter, and older age were more frequent (all P < 0.001) in patients with incorrect diagnosis of normal LV diastolic function based on the measurement of V(p). E(m) appears to be superior to V(p) in the assessment of LV diastolic function in patients with Fabry disease. V(p) fails to detect abnormal LV diastolic function in subjects with pronounced concentric LV remodeling and pseudonormal filling pattern.

Abstract
BACKGROUND Insufficient data describe the relationship of hemodynamic parameters to left ventricular (LV) diastolic flow propagation velocity (Vp) measured using color M-mode Doppler echocardiography. METHODS An in vitro LV model used to simulate LV diastolic inflow with Vp measured under conditions of varying: 1) Stroke volume, 2) heart rate (HR), 3) LV volume, 4) LV compliance, and 5) transmitral flow (TMF) waveforms (Type 1: constant low diastasis flow and Type 2: no diastasis flow). RESULTS Univariate analysis revealed excellent correlations of Vp with stroke volume (r = 0.98), LV compliance (r = 0.94), and HR with Type 1 TMF (r = 0.97). However, with Type 2 TMF, HR was not associated with Vp. LV volume was not related to Vp under low compliance, but inversely related to Vp under high compliance conditions (r = -0.56). CONCLUSION These in vitro findings may help elucidate the relationship of hemodynamic parameters to early diastolic LV filling.

Abstract
Tissue Doppler imaging (TDI) and color M-mode Doppler flow propagation velocity (Vp) are used to assess cardiac function in humans, but the feasibility and applicability of these measurements to murine cardiomyopathic models of heart failure remain unclear. Left ventricular (LV) function was measured by TDI and Vp among mice exhibiting severe dilated cardiomyopathy (TOT), pressure-overload hypertrophy (TAC), and normal controls (NTG). Transmitral flow pattern in TACs and TOTs showed a restrictive filling pattern, but early diastolic mitral annulus velocity was comparable among the three studied groups. Propagation velocity in an anesthetized state was comparable in all three groups. However, while Vp increased in all three groups in the conscious state, the increase in NTGs was statistically greater than in TACs and TOTs. Collectively, results indicate that color M-mode Doppler echocardiography can be used to assess LV function in mice. Furthermore, Vp is depressed by anesthesia, a complication that can lead to misinterpretation of LV function in normal hearts.

Abstract
The physiology of early-diastolic filling comprises ventricular performance and fluid dynamical principles. Elastic recoil and myocardial relaxation rate determine left ventricular early diastolic performance. The integrity of left ventricular synchrony and geometry is essential to maintain the effect of their timely action on early diastolic left ventricular filling. These factors not only are prime determinants of left ventricular pressure decay during isovolumic relaxation and immediately after mitral valve opening; they also instigate the generation of a sufficient intra-ventricular pressure gradient, which enhances efficient early diastolic left ventricular filling. Accurate assessment of diastolic (dys)function by non-invasive techniques has important therapeutic and prognostic implications but remains a challenge to the cardiologist. The evaluation of left ventricular relaxation by the standard Doppler echocardiographic parameters is hindered by their preload dependency. The colour M-mode velocity propagation of early diastolic inflow (Vp) correlates with intra-ventricular pressure gradients and is a largely preload independent index of ventricular diastolic performance. In this article, the physiologic background, utility and limitations of this promising new tool for the study of early diastolic filling are reviewed.

Abstract
BACKGROUND Although color Doppler M-mode propagation velocity (Vp) is preload-independent, the variation in Vp with the temporal variation of preload in the clinical setting has not been evaluated. Because left ventricular filling pressure changes dramatically with treatment of congestive heart failure (CHF), we hypothesized that preload-dependent variations in Vp occur with treatment of CHF. METHODS We performed Doppler echocardiographic and hemodynamic evaluation in 24 patients with CHF (15 men, 62 +/- 10 years) at initial presentation (baseline study) and after CHF had improved with therapy (second study). RESULTS The interval between the baseline and the second study was 48.6 +/- 21.5 hours. Vp decreased between the baseline study (41 +/- 5 cm/s) and the second study (28 +/- 5 cm/s, P <.0001). Only the change in pulmonary capillary wedge pressure (-8.3 +/- 3.3 mm Hg) between the baseline and second study was an independent predictor of the change in Vp (-12.5 +/- 5.9 cm/s) by stepwise linear regression (r = 0.68, P =.0002). CONCLUSIONS Vp decreases significantly with decreases in pulmonary capillary wedge pressure with the treatment of CHF. The preload-dependent variation should be taken into account in the assessment of Vp in patients with CHF.

Abstract
Left ventricular (LV) systolic performance has been acknowledged to have a close relation to LV early diastolic filling and LV relaxation. However, the mechanism showing how good LV systolic function enhances the LV early diastolic filling has not been fully elucidated from the viewpoint of intraventricular flow dynamics. Thus, we investigated this issue in 82 patients with suggested coronary artery disease who underwent cardiac catheterization. Apically directed intraventricular isovolumic relaxation flow (IRF) and the propagation velocity of early diastolic filling flow were measured using pulsed and color Doppler echocardiography. LV ejection fraction and LV relaxation time constant tau were obtained in cardiac catheterization. As we were not able to measure the IRF velocity less than 14 cm/s that was limited by a Doppler low-cut filter, we analyzed the data collected from 78 patients with measurable IRF velocity. The IRF velocity significantly correlated with LV ejection fraction (r = 0.74, P <.001) and with LV relaxation time constant tau (r = -0.31, P <.01). The propagation velocity of early diastolic filling flow significantly correlated with the IRF velocity (r = 0.73, P <.001) and also significantly correlated with LV ejection fraction (r = 0.70, P <.001). Good LV systolic performance augments LV early diastolic filling directly, mediated by IRF. A faster IRF velocity may play a role in delivering good LV systolic performance to LV early diastolic filling.

Abstract
PURPOSE OF REVIEW This review discusses the current and future applications of different echocardiographic modalities in evaluating diastolic function intraoperatively. RECENT FINDINGS Normal diastolic function is required for optimal cardiac performance. There is sufficient evidence to support the significant prevalence of preoperative diastolic dysfunction and its incidence following cardiac surgery, however controversy still exists regarding the impact of diastolic dysfunction on adverse outcomes. Echocardiography provides a relatively safe, practical and noninvasive means to evaluate perioperative diastolic function, however conventional measures may be limited by the impact of changes in heart rate, rhythm and loading conditions. Newer echocardiographic modalities are reportedly less sensitive to acute changes in loading conditions, and may therefore complement the use of conventional echocardiographic techniques in the perioperative period. SUMMARY The availability of effective technology for diagnosing the presence and progression of perioperative diastolic function should assist in the identification of high-risk cardiac surgical patients who may benefit from appropriate triaging and therapeutic intervention.

Abstract
The mechanism of emergence and the clinical significance of apically directed intraventricular flow during isovolumic relaxation were investigated. The relation between the spatial distribution of the flow and left ventricular (LV) apical wall motion abnormality, as well as LV performance, was studied in 97 patients who underwent cardiac catheterization for evaluation of chest pain. According to the distribution of the flow, the patients were classified into the following 3 groups: flow observed in the whole area between the tip of the papillary muscle and the apex (spread flow) (n = 38), flow observed in the same area that did not fill the whole area (localized flow) (n = 15), and no apparent flow observed in the area (without flow) (n = 44). An absence of flow disclosed apical asynergy with a sensitivity of 97% and specificity of 87%. The time constant of LV relaxation was significantly shorter in patients with spread flow than in those without flow. A significant difference was also observed in end-systolic volume index (18.8 +/- 6.8 vs 30.9 +/- 7.7 vs 42.3 +/- 20.2 mL/m(2), spread flow < localized flow < without flow, P <.05) among the 3 groups. The propagation velocity of LV early diastolic filling flow was significantly greater in patients with spread flow (47.0 +/- 8.3 cm/s) than in those with localized flow (30.7 +/- 7.8 cm/s) or without flow (28.6 +/- 7.8 cm/s) (P <.001). These findings indicate that the greater magnitude of LV elastic recoil and the faster LV relaxation in patients without LV apical asynergy produce apically directed intraventricular flow during isovolumic relaxation, enhancing the speed of LV early diastolic filling. Apically directed intraventricular flow during isovolumic relaxation may play an important role as a mediator of better LV systolic performance and LV relaxation to LV early diastolic filling. Absence of apically directed intraventricular flow during isovolumic relaxation is a manifestation of LV apical asynergy and global LV dysfunction from end systole to early diastole.

Abstract
The standard noninvasive method to assess left ventricular diastolic function has been pulsed Doppler echocardiographic recordings of mitral inflow early diastolic (E) and atrial (A) filling velocities and the ratio of E to A, in combination with isovolumic relaxation and deceleration times. Pulmonary venous inflow velocities (systolic, diastolic, and atrial reversal) are used to assess left atrial and left ventricular end-diastolic pressures. These measurements are influenced by changes in preload, including left ventricular end-diastolic pressure, left atrial or pulmonary capillary wedge pressure, and left ventricular volumes. Newer methods such as tissue Doppler imaging (TDI) of the mitral annulus and color M-mode recording of left ventricular diastolic flow propagation (FP) have now evolved as additional techniques for detecting abnormalities in left ventricular diastolic function that can complement the standard pulsed Doppler echocardiography methods. Both TDI and color M-mode flow FP appear to offer distinct advantages as relatively load-independent measures of diastolic function. TDI can be used for measurement of regional diastolic myocardial velocities at the mitral annulus, and it is particularly useful in identifying abnormalities of left ventricular diastolic relaxation or estimation of left ventricular filling pressures. Color M-mode FP can be used for quantification of abnormalities of left ventricular relaxation and diastolic filling characteristics of the left ventricle.
