Echocardiography Course

Lesson 1 • Cardiac Cycle and Hemodynamics

Explains systole, diastole, pressure-volume relationships, and cardiac output determinants. Links physiological events to waveform patterns seen on Doppler imaging.

Lesson 2 • Cardiac Valves and Apparatus

Examines the four cardiac valves, their leaflets, and supporting structures. Provides the anatomical basis for valve assessment in echocardiography.

Lesson 3 • Coronary Artery Anatomy and Territories

Maps coronary artery distribution to myocardial wall segments. Enables correlation of regional wall motion abnormalities with coronary artery disease territories.

Lesson 4 • Great Vessels and Pericardium

Describes the aorta, pulmonary artery, venae cavae, and pericardial layers. Connects vascular anatomy to echo windows and pericardial pathology recognition.

Lesson 1 • Ultrasound Wave Properties

Covers frequency, wavelength, velocity, and acoustic impedance of ultrasound waves. These properties directly determine image resolution and tissue penetration.

Lesson 2 • Transducer Design and Function

Explains piezoelectric elements, transducer types, and beam focusing mechanisms. Selecting the correct transducer is foundational to diagnostic image acquisition.

Lesson 3 • Artifacts and Image Optimization

Identifies common ultrasound artifacts and machine controls used to reduce them. Artifact recognition prevents misdiagnosis and improves diagnostic confidence.

Lesson 4 • Doppler Principles and Modes

Explains the Doppler effect, frequency shift, and angle dependence for velocity measurement. Doppler modes are the basis for all hemodynamic quantification in echocardiography.

Lesson 1 • Subcostal and Suprasternal Views

Demonstrates subcostal four-chamber, IVC, and suprasternal aortic arch views. These windows are critical when parasternal and apical windows are suboptimal.

Lesson 2 • Recognizing Suboptimal Windows

Identifies causes of poor acoustic windows and strategies to improve image quality. Adapting technique to challenging patients is essential for clinical competency.

Lesson 3 • Probe Handling and Patient Positioning

Establishes correct probe orientation conventions, patient positioning, and ergonomic technique. Consistent technique ensures reproducible studies and reduces operator strain.

Lesson 4 • Apical Window Views

Covers apical four-, five-, two-, and three-chamber view acquisition and orientation. Apical views are essential for Doppler interrogation and ventricular function assessment.

Lesson 1 • LV Linear Measurements and M-Mode

Teaches M-mode and 2D-guided linear measurements of LV internal dimensions and wall thickness. These measurements form the basis for LV mass and geometry classification.

Lesson 2 • Volumetric Assessment by Biplane Method

Applies the modified Simpson biplane method to calculate LV end-diastolic and end-systolic volumes. Accurate endocardial tracing technique is emphasized for reproducibility.

Lesson 3 • LV Geometry and Hypertrophy Patterns

Classifies LV geometry using relative wall thickness and LV mass index. Distinguishes concentric hypertrophy, eccentric hypertrophy, and concentric remodeling.

Lesson 4 • Regional Wall Motion Assessment

Evaluates segmental myocardial thickening and endocardial excursion across 17 wall segments. Correlates regional abnormalities with coronary artery territories established in Chapter 1.

Lesson 1 • Mitral Inflow Doppler Parameters

Measures E wave, A wave, E/A ratio, and deceleration time from pulsed-wave Doppler at the mitral tips. These parameters are the primary screening tool for diastolic dysfunction.

Lesson 2 • Physiology of Diastolic Filling

Reviews myocardial relaxation, compliance, and left atrial pressure as determinants of diastolic function. Provides the physiological framework for interpreting diastolic Doppler parameters.

Lesson 3 • Tissue Doppler Imaging of Mitral Annulus

Acquires septal and lateral mitral annular e' and a' velocities using tissue Doppler imaging. The E/e' ratio is the key non-invasive estimate of left ventricular filling pressure.

Lesson 4 • Diastolic Dysfunction Grading Algorithm

Applies the current guideline-recommended algorithm to grade diastolic dysfunction from Grade I to III. Integrates all parameters into a structured diagnostic conclusion.

Lesson 1 • Aortic Regurgitation Evaluation

Assesses aortic regurgitation severity using vena contracta, pressure half-time, and regurgitant volume. Evaluates aortic root and LV remodeling as markers of chronicity.

Lesson 2 • Mitral Regurgitation Evaluation

Grades mitral regurgitation using PISA method, vena contracta, and regurgitant orifice area. Identifies primary versus secondary etiology to guide management strategy.

Lesson 3 • Mitral Stenosis Evaluation

Quantifies mitral valve area by pressure half-time, planimetry, and continuity equation. Assesses valve morphology using the Wilkins score for intervention planning.

Lesson 4 • Aortic Stenosis Evaluation

Measures aortic valve area, mean gradient, and peak velocity to grade aortic stenosis severity. Identifies low-flow, low-gradient variants requiring additional assessment.

Lesson 1 • Pulmonary Hypertension Echocardiographic Criteria

Applies guideline-based echocardiographic probability criteria for pulmonary hypertension diagnosis. Identifies RV remodeling patterns associated with chronic pressure overload.

Lesson 2 • Pulmonary Artery Pressure Estimation

Calculates systolic, diastolic, and mean pulmonary artery pressures from Doppler-derived parameters. Integrates TR jet velocity, IVC findings, and pulmonary regurgitation data.

Lesson 3 • Inferior Vena Cava and Right Atrial Pressure

Measures IVC diameter and collapsibility index to estimate right atrial pressure non-invasively. Accurate RAP estimation is essential for pulmonary pressure calculations.

Lesson 4 • Right Ventricular Anatomy and Dimensions

Measures RV linear dimensions, area, and wall thickness from standard views. Establishes normal reference ranges and criteria for RV dilation.

Lesson 1 • Speckle Tracking and Myocardial Strain

Measures global longitudinal strain and regional strain using speckle tracking echocardiography. Strain detects subclinical dysfunction before ejection fraction declines.

Lesson 2 • Stress Echocardiography

Performs exercise and pharmacological stress echocardiography to detect inducible ischemia and dynamic valve disease. Covers protocol selection, image acquisition, and interpretation criteria.

Lesson 3 • Cardiac Masses and Thrombi

Differentiates intracardiac thrombi, tumors, and normal variants using echocardiographic characteristics. Guides clinical urgency and need for advanced imaging confirmation.

Lesson 4 • Aortic Disease and Congenital Variants

Assesses aortic root, ascending aorta, and arch dimensions and identifies bicuspid aortic valve morphology. Recognizes common congenital variants encountered in adult echocardiography.
