RESUMO
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: 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.
RESUMO
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.

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.

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.
