What it is: A non-invasive ultrasound test where the transducer is placed on the chest to create real-time images of the heart’s chambers, valves, and wall motion.
Purpose: Used to evaluate heart structure and function—including chamber sizes, valve integrity, ejection fraction, and wall motion. Essential for diagnosing cardiomyopathy, valvular disease, congenital defects, heart failure, and more.
Limitations:
Image quality can be reduced in cases of obesity, thin chest walls, or obstructive lung disease.
Some cardiac regions (like the left atrial appendage) are better visualized with advanced imaging (e.g., TEE).
Cost note: In Rajahmundry, the standard 2D echo at Godavari Hospital is available for ₹1,500, which is well within the typical national range of ₹700–₹3,500.
Special 2D Echo Variants
1. Transesophageal Echocardiogram (TEE)
What it is: A semi-invasive test where an ultrasound probe is passed into the esophagus to obtain high-resolution images of heart structures, particularly those not well-visualized via transthoracic echo.
When used:
Detailed valve evaluation
Detecting clots in the atrium or left atrial appendage
Assessing prosthetic valves
During cardiac surgery guidance
Benefits:
Offers clearer, more precise imaging by avoiding interference from chest wall or lungs.
Considerations:
Requires fasting and sedation
More resource-intensive
Typically costs ₹3,000–₹4,500+
2. Dobutamine Stress Echocardiogram (DSE)
What it is: A type of stress echo where dobutamine (IV drug) is used to simulate exercise. It evaluates how the heart performs under stress.
Why use it:
Detects coronary artery disease and ischemia
Identifies wall motion abnormalities
When combined with strain imaging, provides quantitative markers (e.g., Postsystolic Strain Index [PSI]) that are more sensitive than standard visual analysis.
Limitations:
Technically more demanding
Requires continuous monitoring and skilled operators
What it is: An advanced echo technique that tracks natural “speckles” in the myocardium frame by frame to measure strain (deformation) and strain rate (speed of deformation).
Why it’s useful:
Provides angle-independent, quantitative assessment of myocardial function
Detects subtle dysfunction not seen on routine echo
