This dataset contains images slices derived from cine loops and DICOM images collected during point-of-care echocardiography examinations. 2025-12-16 completed London School of Hygiene & Tropical Medicine 10.17037/DATA.00004569 Dataset London School of Hygiene & Tropical Medicine, London, United Kingdom Imperial College London, London, United Kingdom Experiment.Laboratory restricted London, United Kingdom Wellcome Trust UK Research and Innovation TB-HEART Studies UKRI AI Centre for Doctoral Training in Digital Healthcare Dataset DICOM images Images were collected during the TB-HEART study, a cross-sectional longitudinal study exploring cardiac pathology in adults with pulmonary tuberculosis. All participants provided written informed consent. POCUS echocardiograms were collected using a Clarius HD3 handheld ultrasound device at a primary care facility in Zambia. Scans were performed by an infectious disease clinician, who had completed some training in echocardiography in the United Kingdom (UK). The data includes apical four-chamber (A4C), parasternal short-axis (PSAX), and subcostal four-chamber (S-A4C) views from 64 patients. In total, among the 64 patients in the dataset, 34 had PSAX views, 27 had S-A4C views, and 22 had A4C views. Cardiac pathology affecting heart function was observed in a subset of patients, such as pericardial effusion, left ventricular systolic dysfunction, and constrictive physiology. 227510/Z/23/Z en TB-HEART Studies Wellcome Trust 227510/Z/23/Z https://doi.org/10.13039/100010269 UKRI AI Centre for Doctoral Training in Digital Healthcare UK Research and Innovation EP/Y030974 1 https://doi.org/10.13039/100014013
