Artificial Intelligence Echocardiography in Resource‐Limited Regions: Applications and Challenges

Izhan Hamza, Patricia A. Pellikka, Amer Abdulla, Masood Ahmad

Artificial intelligence (AI) is revolutionizing cardiac imaging, including echocardiography. However, AI has scarce penetration in resource‐limited regions. The implementation of AI‐aided echocardiography (AIE) poses unique challenges and opportunities in resource‐limited areas. Some obvious advantages of AIE include aiding image acquisition, interpretation, and triaging patients based on severity...

Rasmus Carter‐Storch, Nils Sofus Borg Mortensen, Mulham Ali, Kristian Laursen, more

Echocardiography > 38 > 12 > 2006 - 2015

Aims New diastolic dysfunction (DD) guidelines were introduced in 2016 to replace the 2009 guidelines, but have not yet been evaluated in aortic stenosis (AS). We aimed to compare the 2009 and 2016 DD guidelines in severe AS patients in terms of association with left ventricular (LV) and left atrial (LA) remodeling, with pulmonary capillary wedge pressure (PCWP) at rest and exercise, and with prognosis...

Conversion of left atrial volume to diameter for automated estimation of sudden cardiac death risk in hypertrophic cardiomyopathy

Huzefa Bhopalwala, Nakeya Dewaswala, Sijia Liu, Christopher G. Scott, more

Echocardiography > 38 > 2 > 183 - 188

Background A subset of patients with hypertrophic cardiomyopathy (HCM) is at high risk of sudden cardiac death (SCD). Practice guidelines endorse use of a risk calculator, which requires entry of left atrial (LA) diameter. However, American Society of Echocardiography (ASE) guidelines recommend the use of LA volume index (LAVI) for routine quantification of LA size. The aims of this study were to...

Alexander C. Egbe, William R. Miranda, Patricia A. Pellikka, Sorin V. Pislaru, more

Congenital Heart Disease > 14 > 4 > 657 - 664

Background We hypothesized that echocardiographic indices of right ventricular to pulmonary artery (RV‐PA) coupling were comparable to cardiac magnetic resonance imaging (CMRI)‐derived RV volumetric indices in predicting disease severity in chronic pulmonary regurgitation (PR). Methods Patients with ≥ moderate PR (2003‐2015) with and without prior CMRI scans were enrolled into the study cohort...

American Heart Journal > 2018 > 199 > C > 156-162

Patients with acute coronary syndrome (ACS) due to unprotected culprit left main coronary artery disease (LMCAD) treated with percutaneous coronary intervention (PCI) are rare, high-risk, and not represented in trials.

Comparison of Valsalva Maneuver, Amyl Nitrite, and Exercise Echocardiography to Demonstrate Latent Left Ventricular Outflow Obstruction in Hypertrophic Cardiomyopathy

Chadi Ayoub, Jeffrey B. Geske, Carolyn M. Larsen, Christopher G. Scott, more

The American Journal of Cardiology > 2017 > 120 > 12 > 2265-2271

Guidelines recommend exercise stress echocardiogram (ESE) for patients with hypertrophic cardiomyopathy (HC) if a 50 mm Hg gradient is not present at rest or provoked with Valsalva or amyl nitrite, to direct medical and surgical management. However, no study has directly compared all 3 methods. We sought to evaluate efficacy and degree of provocation of left ventricular outflow gradients by ESE, and...

Chadi Ayoub, Sushil A. Luis, Joseph J. Maleszewski, Patricia A. Pellikka

Echocardiography > 34 > 11 > 1744 - 1746

Advanced imaging techniques, including contrast echocardiography and CMR, provided valuable characterization and evaluation of a boy with an unusual cardiac mass. Imaging features assisted with differentiation of benign from malignant etiology and excluding thrombus. Accurate imaging techniques saved our patient risks associated with unnecessary surgery or anticoagulation. The ability to accurately...

Intrinsic Wave Propagation of Myocardial Stretch, A New Tool to Evaluate Myocardial Stiffness: A Pilot Study in Patients with Aortic Stenosis and Mitral Regurgitation

Cristina Pislaru, Mahmoud M. Alashry, Jeremy J. Thaden, Patricia A. Pellikka, more

Journal of the American Society of Echocardiography > 2017 > 30 > 11 > 1070-1080

Left ventricular (LV) filling following atrial contraction generates LV myocardial stretch that propagates from base to apex with a speed proportional to myocardial elasticity. The aim of this study was to test the hypothesis that intrinsic velocity propagation of myocardial stretch (iVP) would be altered in patients with valvular disease and chronic LV pressure overload or volume overload, which...

BMC Cardiovascular Disorders > 2017 > 17 > 1 > 1-7

Background Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with a...

Dobutamine Stress Echocardiography: Impact of Abnormal Blood Potassium Levels on Cardiac Arrhythmias

Jared G. Bird, Robert B. McCully, Patricia A. Pellikka, Garvan C. Kane

Journal of the American Society of Echocardiography > 2017 > 30 > 6 > 595-601

Guidelines suggest that an abnormal blood potassium level is a relative contraindication to performing dobutamine stress echocardiography (DSE). However, this has not been previously studied.We reviewed a consecutive series of patients who had potassium testing within 48 hours of undergoing DSE for the evaluation of myocardial ischemia over a 10-year period (N = 13,198). Normal potassium range in...

Joseph Davar, Heidi M. Connolly, Martyn E. Caplin, Marianne Pavel, more

Journal of the American College of Cardiology > 2017 > 69 > 10 > 1288-1304

Carcinoid heart disease is a frequent occurrence in patients with carcinoid syndrome and is responsible for substantial morbidity and mortality. The pathophysiology of carcinoid heart disease is poorly understood; however, chronic exposure to excessive circulating serotonin is considered one of the most important contributing factors. Despite recognition, international consensus guidelines specifically...
