2D Echocardiogram
(2D Echo)
A real-time ultrasound imaging of your heart that shows its structure, function, and blood flow — giving your cardiologist a living picture of your heart in motion.
A 2D Echocardiogram (2D Echo) is a medical imaging technique that uses high-frequency sound waves (ultrasound) to create two-dimensional, real-time images and videos of your heart. It allows cardiologists to directly visualise the heart's chambers, valves, walls, and the major blood vessels connected to it.
Unlike an ECG which records electrical signals, a 2D Echo provides structural and functional information — showing how well the heart muscle is pumping, whether the valves open and close correctly, and if there are any abnormalities in the heart's anatomy.
At Jayam Hrudayalaya, we use state-of-the-art digital echocardiography systems with expert cardiac sonographers and cardiologists to ensure precise, high-resolution diagnostic imaging.

The echocardiogram relies on the piezoelectric effect — a transducer probe sends ultrasound pulses into the chest and receives echoes reflected back from cardiac structures, converting them into real-time images.
Probe Placement
A gel is applied and the transducer probe is placed on specific acoustic windows on the chest wall
Sound Emission
The probe emits high-frequency ultrasound waves (2–10 MHz) into the chest cavity toward the heart
Echo Reception
Sound waves bounce back (echo) off cardiac structures at different speeds depending on tissue density
Signal Processing
The machine processes time-delay and amplitude of echoes to compute precise depth and density maps
Image Formation
Thousands of scan lines combine to form a 2D cross-sectional image updated 30–80 times per second
The sonographer captures images from multiple acoustic windows to get a complete 360° assessment of the heart from different planes:
Parasternal Long Axis
Primary view showing the left ventricle, mitral valve, aortic valve, and left atrium in a longitudinal cross-section.
- LV chamber dimensions (EDD, ESD)
- Interventricular septal thickness
- Posterior wall thickness
- Aortic root and left atrium size
- Mitral and aortic valve morphology
Parasternal Short Axis
Cross-sectional doughnut-like view of the heart at different levels from base to apex, showing circular LV.
- LV wall motion segmental analysis
- Papillary muscle assessment
- Aortic valve (fish-mouth view)
- Pulmonary artery and valve
- Right ventricular dimensions
Apical 4-Chamber
The most informative view showing all four heart chambers simultaneously, obtained from the cardiac apex.
- All 4 chambers in one view
- Biventricular function comparison
- Mitral & tricuspid valve assessment
- Ejection fraction calculation
- Atrial sizes and septum
Subcostal & Suprasternal
Alternative windows under the ribcage and above the sternum — essential when parasternal windows are poor.
- IVC diameter for CVP estimation
- Pericardial effusion detection
- Aortic arch and descending aorta
- Congenital defects (ASD, VSD)
- Useful in COPD / obese patients
Your 2D Echo report contains these important measurements — here's what each means:
| Parameter | Abbreviation | Normal Range | Clinical Significance | Abnormality |
|---|---|---|---|---|
| Ejection Fraction | EF / LVEF | 55–75% | Percentage of blood pumped out per beat — most critical heart function parameter | <40% = Systolic HF 40–54% = Borderline |
| LV End Diastolic Diameter | LVEDD | 42–59 mm | Size of left ventricle when fully relaxed and filled with blood | >59 mm = Dilated LV |
| LV End Systolic Diameter | LVESD | 24–39 mm | Size of left ventricle when fully contracted — smaller than LVEDD | >40 mm = Systolic dysfunction |
| Interventricular Septum | IVS | 7–11 mm | Thickness of the muscle wall separating left and right ventricles | >13 mm = HCM |
| Left Atrium Size | LA | 27–38 mm | Diameter of the left upper chamber; enlarges with mitral valve disease / AF | >40 mm = LA enlargement |
| Aortic Root | AO | 20–37 mm | Diameter of the aorta at its origin from the left ventricle | >40 mm = Aortic dilatation |
| Mitral Valve Area | MVA | 4–6 cm² | Opening area of the mitral valve during diastole; reduced in MS | <1 cm² = Severe MS 1–1.5 = Moderate |
| Right Ventricular Systolic Pressure | RVSP / PASP | <35 mmHg | Estimated pulmonary artery pressure — elevated in pulmonary hypertension | >50 mmHg = Severe PHT |
| Pericardial Effusion | PE | None / Trace | Fluid in the pericardial sac surrounding the heart | >20 mm = Tamponade risk |
| E/A Ratio (Diastolic) | E/A | 0.75–1.5 | Ratio indicating diastolic filling pattern — E=early, A=atrial filling waves | <0.75 = Grade I DD E/A >2 = Grade III |
2D Echocardiography is the cornerstone for diagnosing a wide spectrum of cardiac conditions:
Heart Failure (HF)
Determines systolic (reduced EF) vs diastolic (preserved EF) heart failure, guides treatment decisions and prognosis.
Myocardial Infarction
Detects regional wall motion abnormalities (RWMA) indicating areas of infarcted or ischaemic myocardium after a heart attack.
Mitral Valve Disease
Identifies mitral stenosis, mitral regurgitation, or mitral valve prolapse with severity grading and MVA calculation.
Aortic Valve Disease
Diagnoses aortic stenosis (calcified, rheumatic) and aortic regurgitation — assessing valve gradients and area.
Pericardial Effusion
Detects and quantifies fluid around the heart, identifies cardiac tamponade — a life-threatening emergency requiring urgent drainage.
Cardiomyopathy (HCM/DCM)
Hypertrophic cardiomyopathy (HCM) with IVS thickening or dilated cardiomyopathy (DCM) with enlarged chambers and poor EF.
Pulmonary Hypertension
Estimates RVSP and PASP to diagnose and grade pulmonary arterial hypertension affecting the right heart.
Congenital Heart Defects
Detects ASD (atrial septal defect), VSD (ventricular septal defect), PDA, tetralogy of Fallot, and other congenital anomalies.
Infective Endocarditis
Identifies vegetations on heart valves caused by bacterial infection — guides antibiotic therapy and surgical planning.
LV Hypertrophy (LVH)
Measures LV wall thickness — hypertrophy due to hypertension, HCM, or aortic stenosis confirmed by echo criteria.
Intracardiac Thrombus
Detects blood clots inside heart chambers — especially LV apex post-MI and LA appendage in atrial fibrillation.
Diastolic Dysfunction
Grades relaxation abnormality of the LV from Grade I (impaired relaxation) to Grade III (restrictive pattern).
Modern echocardiography combines structural 2D imaging with various Doppler techniques to measure blood flow velocities and gradients across heart valves and chambers:
Pulsed Wave Doppler (PW)
Measures blood flow velocity at a specific location. Used for mitral inflow (E/A ratio), pulmonary veins, and LVOT flow assessment.
Continuous Wave Doppler (CW)
Measures high-velocity flows along the entire beam. Calculates peak gradients across stenotic valves using the modified Bernoulli equation.
Colour Flow Doppler (CFM)
Maps blood flow direction and turbulence in colour (red = toward probe, blue = away). Identifies valve regurgitation, septal defects, and abnormal jets.
Tissue Doppler (TDI)
Measures myocardial velocities — especially mitral annular e' velocity to assess diastolic function and calculate E/e' ratio for filling pressures.
Your cardiologist will recommend a 2D Echo in these clinical situations:
Chest Pain / Angina
To assess LV function and wall motion after ischaemia or infarction
Breathlessness
Evaluate heart failure, valvular disease, or pulmonary hypertension
Heart Murmur
Identify and characterise valve disease causing abnormal heart sounds
Stroke / TIA
Detect cardiac sources of embolism — clots, PFO, vegetations
Chemotherapy Monitoring
Serial EF monitoring for patients on cardiotoxic cancer drugs
Pre-operative Clearance
Assess cardiac function before major non-cardiac surgery
Pregnancy
Safe evaluation of cardiac disease in pregnant women without radiation
Congenital Screening
Detect structural heart defects in newborns and children
Hypertension Follow-up
Assess LV hypertrophy and diastolic dysfunction in hypertensive patients
Athletes / Sports Screening
Rule out HCM and other structural diseases before competitive sport
A 2D Echo requires minimal preparation. Follow these simple steps for the best quality scan:
No Fasting Required
For a routine transthoracic echo, you may eat and drink normally. No fasting is necessary unless advised differently by your cardiologist.
Continue Regular Medications
Take all your regular medications as usual unless your doctor specifically instructs otherwise before the test.
Wear Comfortable Clothing
Wear a loose, easily removable top. You will be asked to undress from the waist up and lie on a couch — a hospital gown will be provided.
Avoid Lotions on Chest
Do not apply creams, oil, or powder on your chest before the echo — they interfere with the ultrasound gel coupling and image quality.
Inform About Implants
Inform the technician if you have a pacemaker, ICD, or any chest implant — the test is still safe but your cardiologist should be informed.
Relax and Stay Still
The echo requires you to lie still and occasionally hold your breath for a few seconds. Staying relaxed improves image quality significantly.
Both are cardiac tests, but they measure completely different things and are often ordered together for a complete heart evaluation:
🫀 2D Echo (Echocardiogram)
Structural & functional cardiac imaging
⚡ ECG (Electrocardiogram)
Electrical activity recording
