ABSTRACT
BACKGROUND: Guidelines recommend 3D echocardiography (3DE) to assess left ventricular ejection fraction (LVEF) on transthoracic echocardiogram (TTE) when possible, but it is unclear which factors are most strongly associated with reporting 3DE LVEF in real-world practice. METHODS: We evaluated 3DE LVEF reporting by age, sex, BMI, TTE location and variation in reporting by sonographer and reader. All TTEs were performed without contrast enhancement agent at a large medical center from 9/2015 to 12/2020 using ultrasound machines capable of 3DE. We used multivariable logistic regression to assess which factors were most associated with reporting 3DE LVEF. RESULTS: Among 35 641 TTEs included in this study, 57.4% were performed on women. 3DE LVEF was reported on 18 391 TTEs (51.6% of cohort; 50.5% for women and 52.4% for men). Portable inpatient TTEs (n = 5569) had the lowest rates of 3DE LVEF reporting (30.9%), while general outpatient TTEs (n = 15 933) had greater reporting (56.9%). Outpatient TTEs with an indication for chemotherapy (n = 3244) had the highest rates of 3DE LVEF (87.2%). The median (IQR) percentage of TTEs reporting 3D LVEF was 52.7% (43.1%-68.1%) among sonographers and 51.6% (46.5%-59.6%) among readers. Among 20082 (56.3%) TTEs with 3DE LVEF measured by sonographers, 91.6% were included by readers in the final report. After adjustment, performing sonographer in the highest reporting quartile was most strongly associated with reporting 3DE LVEF (OR 7.04, 95% CI 6.55-7.56), while an inpatient portable study had the strongest negative association for reporting (OR .38, 95% CI .35-.40). CONCLUSIONS: Use of 3DE LVEF in real-world practice varies substantially based on performing sonographer and is low for hospitalized patients, but can be frequently used for chemotherapy. Initiatives are needed to increase sonographer 3DE acquisition in most clinical settings.

BACKGROUND: There are limited data about the epidemiology and secondary stroke prevention strategies used for patients with depressed left ventricular ejection fraction (LVEF) and sinus rhythm following an acute ischemic stroke (AIS). We sought to describe the prevalence of LVEF ≤40% and sinus rhythm among patients with AIS and antithrombotic treatment practice in a multi-center cohort from 2002 to 2018. METHODS: This was a multi-center, retrospective cohort study comprised of patients with AIS hospitalized in the Greater Cincinnati Northern Kentucky Stroke Study and 4 academic, hospital-based cohorts in the United States. A 1-stage meta-analysis of proportions was undertaken to calculate a pooled prevalence. Univariate analyses and an adjusted multivariable logistic regression model were performed to identify demographic, clinical, and echocardiographic characteristics associated with being prescribed an anticoagulant upon AIS hospitalization discharge. RESULTS: Among 14 338 patients with AIS with documented LVEF during the stroke hospitalization, the weighted pooled prevalence of LVEF ≤40% and sinus rhythm was 5.0% (95% CI, 4.1-6.0%; I2, 84.4%). Of 524 patients with no cardiac thrombus and no prior indication for anticoagulant who survived postdischarge, 200 (38%) were discharged on anticoagulant, 289 (55%) were discharged on antiplatelet therapy only, and 35 (7%) on neither. There was heterogeneity by site in the proportion discharged with an anticoagulant (22% to 45%, P<0.0001). Cohort site and National Institutes of Health Stroke Severity scale >8 (odds ratio, 2.0 [95% CI, 1.1-3.8]) were significant, independent predictors of being discharged with an anticoagulant in an adjusted analysis. CONCLUSIONS: Nearly 5% of patients with AIS have a depressed LVEF and are in sinus rhythm. There is significant variation in the clinical practice of antithrombotic therapy prescription by site and stroke severity. Given this clinical equipoise, further study is needed to define optimal antithrombotic treatment regimens for secondary stroke prevention in this patient population.

Atrial cardiomyopathy has been recognized as having important consequences for cardiac performance and clinical outcomes. The pathophysiological role of the left atrial (LA) appendage and the effect of percutaneous left atrial appendage occlusion (LAAO) upon LA mechanics is incompletely understood. We evaluated if changes in LA stiffness due to endocardial LAAO can be detected by LA pressure-volume (PV) analysis and whether stiffness parameters are associated with baseline characteristics. Patients undergoing percutaneous endocardial LAAO (n = 25) were studied using a novel PV analysis using near-simultaneous three-dimensional LA volume measurements by transesophageal echocardiography (TEE) and direct invasive LA pressure measurements. LA stiffness (dP/dV, change in pressure with change in volume) was calculated before and after LAAO. Overall LA stiffness significantly increased after LAAO compared with baseline (median, 0.41-0.64 mmHg/mL; P ⪠0.001). LA body stiffness after LAAO correlated with baseline LA appendage size by indexed maximum depth (Spearman's rank correlation coefficient Rs = 0.61; P < 0.01). LA stiffness change showed an even stronger correlation with baseline LA appendage size by indexed maximum depth (Rs = 0.70; P < 0.001). We found that overall LA stiffness increases after endocardial LAAO. Baseline LA appendage size correlates with the magnitude of increase and LA body stiffness. These findings document alteration of LA mechanics after endocardial LAAO and suggest that the LA appendage modulates overall LA compliance.NEW & NOTEWORTHY Our study documents a correlation of LA appendage remodeling with the degree of chronically abnormal LA body stiffness. In addition, we found that LA appendage size was the baseline parameter that best correlated with the magnitude of a further increase in overall LA stiffness after appendage occlusion. These findings offer insights about the LA appendage and LA mechanics that are relevant to patients at risk for adverse atrial remodeling, especially candidates for LA appendage occlusion.

Three-dimensional echocardiography (3DE) has emerged in recent decades from a conceptual, research tool to an important, useful imaging technique that can informatively impact daily clinical practice. However, its adoption into the modern-day echo laboratory requires the acknowledgment of its value, coupled with proper leadership, education, and resources to implement and integrate its use with conventional echo techniques. 3DE integration involves important updates regarding equipment and patient selection, assimilation of 3D protocols into current clinical routine, laboratory workflow adaptation, storage, and reporting. This review will provide a practical blueprint and key points of how to integrate 3DE into today's echo laboratory, necessary resources to implement 3D workflow, logistical challenges that remain, and future directions to further improve assimilation of this relevant echo technique into the laboratory.

INTRODUCTION AND OBJECTIVES: Mitral valve (MV) prolapse is highly prevalent in patients with atrial septal defect (ASD). Abnormal left ventricular geometry has been proposed as the main mechanism of MV prolapse in ASD, however, the changes in the morphology of the MV apparatus remain to be clarified. Our aim was to assess the MV geometry in patients with ASD and MV prolapse. METHODS: We evaluated 99 patients (73% female, median age 40 years) with ASD who underwent a three-dimensional transesophageal echocardiogram. Three-dimensional analysis of the MV was done using dedicated automated software. Transthoracic echocardiographic parameters were assessed post ASD closure in 28 patients. RESULTS: MV prolapse was found in 39% of patients. Although smaller left ventricular dimensions and greater interatrial shunt were found in patients with MV prolapse compared with those without prolapse, there was no difference in the subvalvular parameters. MV prolapse was associated with larger mitral anterior-posterior diameter, anterolateral-posteromedial diameter, anterior perimeter, posterior perimeter, total perimeter, and anterior leaflet area (all p < 0.05). Mitral regurgitation was more frequent in patients with MV prolapse (80 vs. 48%, p = 0.002). CONCLUSIONS: In patients with ASD, the main mechanism of MV prolapse is the presence of an organic primary process of the MV apparatus (excessive anterior mitral leaflet tissue and mitral annular enlargement).

Multisystem inflammatory syndrome in children (MIS-C) is one of the most significant sequela of coronavirus disease 2019 (COVID-19) in children. Emerging literature has described myocardial dysfunction in MIS-C patients using traditional and two-dimensional speckle tracking echocardiography in the acute phase. However, data regarding persistence of subclinical myocardial injury after recovery is limited. We aimed to detect these changes with deformation imaging, hypothesizing that left ventricular global longitudinal (GLS) and circumferential strain (GCS) would remain impaired in the chronic phase despite normalization of ventricular function parameters assessed by two-dimensional echocardiography. A retrospective, single-institution review of 22 patients with MIS-C was performed. Fractional shortening, GLS, and GCS, along with regional longitudinal (RLS) and circumferential strain (RCS) were compared across the acute, subacute, and chronic timepoints (presentation, 14-42, and > 42 days, respectively). Mean GLS improved from - 18.4% in the acute phase to - 20.1% in the chronic phase (p = 0.4). Mean GCS improved from - 19.4% in the acute phase to - 23.5% in the chronic phase (p = 0.03). RCS and RLS were impaired in the acute phase and showed a trend towards recovery by the chronic phase, with the exception of the basal anterolateral segment. In our longitudinal study of MIS-C patients, GLS and GCS were lower in the acute phase, corroborating with left ventricular dysfunction by traditional measures. Additionally, as function globally recovers, GLS and GCS also normalize. However, some regional segments continue to have decreased strain values which may be an important subclinical marker for future adverse events.

Many novel percutaneous interventions are being developed for application in the tricuspid valve position. At the present time, there are no commercially available devices for this application. There has been mounting evidence supporting the safety and efficacy of using the MitraClip system on the tricuspid valve. This review summarizes the peer reviewed data available to date supporting this procedure, outlines the step-by-step maneuvers using the MitraClip system for this application, and imaging techniques used prior to and during the procedure.

BACKGROUND: Detecting early impact of coronary artery bypass grafting (CABG) on left ventricular (LV) function is important because such measures may contribute to meaningful improvement in clinical outcomes. We aimed to gain knowledge about acute changes of LV performance during surgical revascularization using three-dimensional speckle tracking echocardiography (3D STE). METHODS: Thirty-five patients scheduled for CABG surgery who underwent intraoperative transesophageal echocardiography (TEE) were enrolled (mean age 68.9 ± 7.3 years). TEE was performed before and after surgery, as well as before and after grafting. 3D LV ejection fraction (LVEF), tissue motion annular displacement (TMAD) of the mitral valves, 3D global longitudinal strain (GLS), global circumferential strain (GCS), twist, and torsion were quantified. Regional longitudinal strain (LS) was calculated based on coronary perfusion territories in a 16-segment LV model. RESULTS: Despite the absence of change in TMAD and 3D LVEF, 3D GLS (-18.6 ± 4.3% at baseline vs -16.0 ± 4.0% after surgery, P = .01) was significantly decreased, followed with no significant effect on GCS, twist, and torsion during surgery. 3D GLS correlated significantly with 3D LVEF (r between -0.34 and -0.51, P < .05 for all) under the whole operation. Territorial LS did not increase immediately after surgery. CONCLUSION: 3D speckle tracking imaging allows for detailed and direct evaluation of myocardial deformation, though impaired LV longitudinal function is still apparent immediately after surgery. GLS is more sensitive to an acute reduction in LV function than conventional parameters, which can be potentially useful for serial monitoring of functional recovery.

BACKGROUND: Right ventricle (RV) evaluation requires dedicated imaging to achieve a comprehensive functional and anatomical assessment. Right ventricular imaging could be technically difficult which results in suboptimal visibility and inconsistent assessment between observers. The aim of this study was to assess feasibility and the additive value of contrast enhancement for right ventricular evaluation. METHODS: Eighty patients referred for clinically indicated echocardiography studies were included. Patients with irregular rhythms were excluded. Dedicated RV-focused view was attained; RV dimensions measured, and RV segment visualization and wall motion were assessed with and without contrast enhancement. Paired sample t test was used to compare continuous variables, Wilcoxon signed-rank test to compare segments visualization on enhanced versus (vs) nonenhanced images, and Cohen kappa coefficient to assess the agreement of wall motion between two observers. Reproducibility was measured by the absolute mean difference method. RESULTS: A total of 240 total segments of 80 patients were analyzed, and 178 (74%) were visible on unenhanced while 221 (92%) on enhanced images, P < .05. Further, RV measurements on enhanced images were consistently larger on RV focused, SAX, and RVOT. Inter- and intra-observer reproducibility showed a higher reproducibility with a lower bias on enhanced images. Absolute agreement on RV segmental wall motion between two independent observers was higher on enhanced images. Percent agreement was 78% on UE vs 89% on CE. CONCLUSION: Contrast RV imaging is feasible and improves RV segment visualization and inter-observer agreement. Compared with unenhanced images, RV measurements on contrast images are larger and more reproducible with lower bias.

PURPOSE: Endocardial involvement documented by echocardiography is a major criterion of the modified Duke criteria (MDC) for infective endocarditis (IE). Though transesophageal echocardiography (TEE) is sensitive in the diagnosis of IE, it can be inappropriately used. METHODS: This retrospective study included all patients who underwent TEE due to bacteremia, fever, and/or endocarditis in a single, tertiary academic medical center in 2013. Data collected from electronic medical charts were as follows: demographics, history, physical examination, blood cultures, and transthoracic (TTE) and TEE findings. Cases were categorized based on appropriate use criteria (AUC) and MDC. An infectious disease (ID) specialist reviewed cases with rarely appropriate TEE use. RESULTS: In the 194 patients included, 147 (75.8%) were rated as appropriate, 36 (18.6%) rarely appropriate, and 11 (5.6%) uncertain. Of the 36 with rarely appropriate TEEs, using MDC 31 (86%) were rejected and 5 (14%) were possible for IE. Retrospective chart review by an ID specialist determined that 10 of these patients warranted TEE due to compelling issues, including immunosuppression or complicated infection. CONCLUSIONS: In this retrospective cohort, almost one fifth of cases were rated as rarely appropriate. However, a review of these cases showed that TEE was often pursued when the clinical situation involved immunosuppression or complex infectious process. There remains room for improvement to our screening process for TEE and a need to implement a nuanced educational plan to better precisely identify appropriate cases for TEE usage.

The accurate identification of thrombus in the left atrial appendage with transesophageal echocardiogram (TEE) in patients with atrial fibrillation (AF) before cardioversion is essential. Most of these patients have some grade of spontaneous echo contrast (SEC). Severe SEC is often called "sludge," and its prognosis and treatment are still controversial. Current guidelines suggest the use of ultrasound enhancing agents (UEAs) when significant SEC is present. However, little is known about the utility of the UEAs in the differentiation between sludge and less severe SEC.

BACKGROUND: Mitral regurgitation in ischemic heart disease (IMR) is a strong predictor of outcome but until now, pathophysiology is not sufficiently understood and treatment is not satisfying. We aimed to systematically evaluate structural and functional mitral valve leaflet and annular characteristics in patients with IMR to determine the differences in geometric and dynamic changes of the MV between significant and mild IMR. METHODS: Thirty-seven patients with IMR (18 mild (m)MR, 19 significant (moderate+severe) (s)MR) and 33 controls underwent TEE. 3D volumes were analyzed using 3D feature-tracking software. RESULTS: All IMR patients showed a loss of mitral annular motility and non-planarity, whereas mitral annulus dilation and leaflet enlargement occurred in sMR only. Active-posterior-leaflet-area decreased in early systole in all three groups accompanied by an increase in active-anterior-leaflet-area in early systole in controls and mMR but only in late systole in sMR. CONCLUSIONS: In addition to a significant enlargement and loss in motility of the MV annulus, patients with significant IMR showed a spatio-temporal alteration of the mitral valve coaptation line due to a delayed increase in active-anterior-leaflet-area. This abnormality is likely to contribute to IMR severity and is worth the evaluation of becoming a parameter for clinical decision-making. Further, addressing the leaflets aiming to increase the active leaflet-area is a promising therapeutic approach for significant IMR. Additional studies with a larger sample size and post-operative assessment are warranted to further validate our findings and help understand the dynamics of the mitral valve.

BACKGROUND: It is unclear whether advances in management of acute coronary syndrome (ACS) and introduction of novel oral anticoagulants have changed outcomes in patients with ACS with concomitant atrial fibrillation (AF). OBJECTIVE: This study aimed to examine the incidence of AF in patients admitted for ACS and to evaluate its association with adverse outcomes, given the recent advances in management of both diseases. METHODS: Natural language processing search algorithms identified AF in patients admitted with ACS across 13 Northwell Health Hospitals from 2015 to 2021. Hierarchical generalized linear mixed modeling was used to assess the association between AF and in-hospital mortality, bleeding, and stroke outcomes; marginal Cox regression modeling was used to assess the association between AF and postdischarge mortality. RESULTS: Of 12,315 patients admitted for ACS, 3018 (24.5%) had AF with 1609 (53.3%) newly diagnosed. AF patients more commonly received anticoagulation with an oral anticoagulant (80.4% vs 12.3%) or heparin (61.9% vs 56.9%), had lengthier intensive care unit stay (72 vs 49 hours), and underwent fewer percutaneous coronary interventions (31.9% vs 53.1%). In-hospital bleeding, stroke, and mortality were higher in the AF group (15.3% vs 5.0%, 7.4% vs 2.4%, and 6.9% vs 2.1%, respectively). AF was an independent risk factor for all in-hospital outcomes (odds ratios of 2.5, 2.7, and 2.0 for bleeding, stroke, and mortality, respectively) as well as for postdischarge mortality (hazard ratio, 1.3; 95% CI, 1.2-1.5). CONCLUSION: AF is present in 25% of ACS patients and increases risk of in-hospital and postdischarge adverse outcomes. Additional data are required to direct optimal management.

BACKGROUND: Accurate assessment of aortic valve (AV) stenosis (AS) on transthoracic echocardiogram is crucial for appropriate clinical management. However, discordance between aortic valve area (AVA) and Doppler can complicate the diagnosis of severe AS in low-gradient (LG) AS phenotypes. METHODS: We reviewed 220 consecutive patients with suspected severe AS and AVA ≤1.0 cm2 on transthoracic echocardiogram who were evaluated for transcatheter AV replacement (TAVR) within a large health system from 2015 to 2019. We compared AV calcium score and aorto-mitral angle (AMA) on 3-chamber views from ECG-gated cardiovascular CT among patients with high-gradient (HG) AS (N = 19), paradoxical low-flow low-gradient (PLFLG) AS (N = 24) and normal-flow low-gradient (NFLG) AS (N = 14). RESULTS: All groups had comparable age, comorbidities, and AV calcium scores. Compared to patients with HG AS (mean AMA 120 ± 10°), those with PLFLG AS (104 ± 12°; p < 0.001) and NFLG AS (106 ± 13°; p = 0.008) had narrower mean AMA values on cardiovascular CT. CONCLUSION: LG AS patients have significantly narrower AMA than HG AS patients on cardiovascular CT. Due to difficulty obtaining parallel Doppler alignment, narrower AMA may contribute to AVA-Doppler discordance on echocardiogram. These findings emphasize the need for additional information in the setting of LG AS.

OBJECTIVES: Prior data indicate a very rare risk of serious adverse drug reaction (ADR) to ultrasound enhancement agents (UEAs). We sought to evaluate the frequency of ADR to UEA administration in contemporary practice. METHODS: We retrospectively reviewed 4 US health systems to characterize the frequency and severity of ADR to UEA. Adverse drug reactions were considered severe when cardiopulmonary involvement was present and critical when there was loss of consciousness, loss of pulse, or ST-segment elevation. Rates of isolated back pain and headache were derived from the Mayo Clinic Rochester stress echocardiography database where systematic prospective reporting of ADR was performed. RESULTS: Among 26,539 Definity and 11,579 Lumason administrations in the Mayo Clinic Rochester stress echocardiography database, isolated back pain or headache was more frequent with Definity (0.49% vs 0.04%, P < .0001) but less common with Definity infusion versus bolus (0.08% vs 0.53%, P = .007). Among all sites there were 201,834 Definity and 84,943 Lumason administrations. Severe and critical ADR were more frequent with Lumason than with Definity (0.0848% vs 0.0114% and 0.0330% vs 0.0010%, respectively; P < .001 for each). Among the 3 health systems with >2,000 Lumason administrations, the frequency of severe ADR with Lumason ranged from 0.0755% to 0.1093% and the frequency of critical ADR ranged from 0.0293% to 0.0525%. Severe ADR rates with Definity were stable over time but increased in more recent years with Lumason (P = .02). Patients with an ADR to Lumason since the beginning of 2021 were more likely to have received a COVID-19 vaccination compared with matched controls (88% vs 75%; P = .05) and more likely to have received Moderna than Pfizer-Biotech (71% vs 26%, P < .001). CONCLUSION: Severe and critical ADR, while rare, were more frequent with Lumason, and the frequency has increased in more recent years. Additional work is needed to better understand factors, including associations with recently developed mRNA vaccines, which may be contributing to the increased rates of ADR to UEA since 2021.

In patients with significant cardiac valvular disease, intervention with either valve repair or valve replacement may be inevitable. Although valve repair is frequently performed, especially for mitral and tricuspid regurgitation, valve replacement remains common, particularly in adults. Diagnostic methods are often needed to assess the function of the prosthesis. Echocardiography is the first-line method for noninvasive evaluation of prosthetic valve function. The transthoracic approach is complemented with two-dimensional and three-dimensional transesophageal echocardiography for further refinement of valve morphology and function when needed. More recently, advances in computed tomography and cardiac magnetic resonance have enhanced their roles in evaluating valvular heart disease. This document offers a review of the echocardiographic techniques used and provides recommendations and general guidelines for evaluation of prosthetic valve function on the basis of the scientific literature and consensus of a panel of experts. This guideline discusses the role of advanced imaging with transesophageal echocardiography, cardiac computed tomography, and cardiac magnetic resonance in evaluating prosthetic valve structure, function, and regurgitation. It replaces the 2009 American Society of Echocardiography guideline on prosthetic valves and complements the 2019 guideline on the evaluation of valvular regurgitation after percutaneous valve repair or replacement.

As the volume and complexity of catheter ablation of atrial fibrillation (AF) continue to rise, there is increasing attention directed at reducing exposure to ionizing radiation. This has led to the emergence of intracardiac echocardiography (ICE) as a stand-alone imaging modality guiding AF ablation. In addition to directing transseptal puncture, ICE may be used to identify left atrial structures and to guide the manipulation of catheters. ICE may also be used to visualize the esophagus in real-time and to assist with early identification of procedural complications. This review provides detailed step-by-step directions for identification of relevant structures and summarizes the use of ICE during AF ablation.

IMPORTANCE: There is a need to describe contemporary outcomes of surgical aortic valve replacement (AVR) as the population ages and transcatheter options emerge. OBJECTIVE: To assess procedure rates and outcomes of surgical AVR over time. DESIGN, SETTING, AND PARTICIPANTS: A serial cross-sectional cohort study of 82,755,924 Medicare fee-for-service beneficiaries undergoing AVR in the United States between 1999 and 2011. MAIN OUTCOMES AND MEASURES: Procedure rates for surgical AVR alone and with coronary artery bypass graft (CABG) surgery, 30-day and 1-year mortality, and 30-day readmission rates. RESULTS: The AVR procedure rate increased by 19 (95% CI, 19-20) procedures per 100,000 person-years over the 12-year period (P<.001), with an age-, sex-, and race-adjusted rate increase of 1.6% (95% CI, 1.0%-1.8%) per year. Mortality decreased at 30 days (absolute decrease, 3.4%; 95% CI, 3.0%-3.8%; adjusted annual decrease, 4.1%; 95% CI, 3.7%- 4.4%) per year and at 1 year (absolute decrease, 2.6%; 95% CI, 2.1%-3.2%; adjusted annual decrease, 2.5%; 95% CI, 2.3%-2.8%). Thirty-day all-cause readmission also decreased by 1.1% (95% CI, 0.9%-1.3%) per year. Aortic valve replacement with CABG surgery decreased, women and black patients had lower procedure and higher mortality rates, and mechanical prosethetic implants decreased, but 23.9% of patients 85 years and older continued to receive a mechanical prosthesis in 2011. CONCLUSIONS AND RELEVANCE: Between 1999 and 2011, the rate of surgical AVR for elderly patients in the United States increased and outcomes improved substantially. Medicare data preclude the identification of the causes of the findings and the trends in procedure rates and outcomes cannot be causally linked. Nevertheless, the findings may be a useful benchmark for outcomes with surgical AVR for older patients eligible for surgery considering newer transcatheter treatments.

A multidisciplinary care team model, or Heart Team approach, has become a central tenet of cardiovascular care. Though initially applied to the management of heart transplantation and subsequently complex coronary artery disease, the Heart Team is now utilized broadly across cardiovascular medicine, including in the treatment of valvular disease, pulmonary embolism, cardiogenic shock, high-risk pregnancies in patients with pre-existing cardiovascular disease, and adult congenital heart disease. The Heart Team model improves interdisciplinary collaboration among specialties, adherence to societal guidelines, and shared decision-making with patients and families. In this review, we highlight the development and rationale supporting the Heart Team model, address the challenges of implementing a multidisciplinary care team, and discuss the optimal methods to continue to build, optimize, and implement this approach.
