Echocardiography Views in RadiologyEchocardiography uses ultrasound imaging to visualize cardiac structures through standardized views that provide comprehensive assessment of the heart. Understanding these views is essential for accurate diagnosis of cardiac conditions.Transthoracic Echocardiography (TTE) ViewsParasternal
ViewsParasternal Long-Axis View (PLAX):
The transducer is placed at the left parasternal border (3rd-4th intercostal space). This view displays the left ventricle, left atrium, aortic root, aortic valve, mitral valve, and interventricular septum in a longitudinal plane. It's ideal for assessing left ventricular wall thickness, chamber dimensions, valve morphology, and left ventricular outflow tract.Parasternal Short-Axis Views (PSAX):
Obtained by rotating the transducer 90 degrees from the PLAX position. Multiple levels are imaged:
Aortic valve level: Shows aortic valve, pulmonary valve, tricuspid valve, right ventricular outflow tract, and interatrial septum
Mitral valve level: Displays mitral valve opening in "fish mouth" appearance
Papillary muscle level: Shows left ventricular walls and papillary muscles, useful for assessing wall motion abnormalities
Apical level: Visualizes apex of left ventricle
Apical ViewsThe transducer is placed at the cardiac apex (usually 5th intercostal space, midclavicular line).Apical Four-Chamber View (A4C):
Displays all four cardiac chambers, mitral valve, tricuspid valve, interatrial septum, and interventricular septum. Essential for evaluating chamber sizes, ventricular function, valve regurgitation, and septal defects.Apical Five-Chamber View (A5C):
Similar to A4C with slight anterior angulation to include the left ventricular outflow tract and aortic valve. Used for assessing aortic stenosis and subaortic obstruction.Apical Two-Chamber View (A2C):
Shows left ventricle, left atrium, mitral valve, and inferior and anterior walls of the left ventricle. Useful for wall motion analysis and left atrial assessment.Apical Three-Chamber View (A3C or Apical Long-Axis):
Displays left ventricle, left atrium, aortic valve, mitral valve, and left ventricular outflow tract. Similar to PLAX but from apical approach.Subcostal ViewsTransducer placed below the xiphoid process, angled superiorly and leftward.Subcostal Four-Chamber View:
Alternative window when parasternal and apical views are difficult (obese patients, COPD). Shows all four chambers with excellent visualization of interatrial septum for detecting atrial septal defects.Subcostal Short-Axis View:
Visualizes right and left ventricles in cross-section.Subcostal Inferior Vena Cava (IVC) View:
Assesses IVC diameter and respiratory variation to estimate right atrial pressure and volume status.Suprasternal ViewsTransducer placed in the suprasternal notch.Suprasternal Long-Axis View:
Images the aortic arch, ascending and descending aorta, brachiocephalic vessels. Used for detecting aortic coarctation, dissection, and arch abnormalities.Suprasternal Short-Axis View:
Shows pulmonary artery bifurcation and right pulmonary artery.
