Echocardiography.
Abstract: Diagnostic ultrasound permits the clinician to image the beating heart, quantitate cardiac dimensions, identify specific congenital and acquired cardiac lesions, and estimate the degree of cardiac compensation and muscle failure that accompanies a specific lesion. The M-mode (motion) echocardiogram and two-dimensional echocardiogram are complementary studies that have proved useful for identification of cardiac septal defects, endocarditis, pericardial effusion, intracardiac shunting, cardiomegaly, and heart muscle failure. Appreciation of the technique and basic knowledge of the types of information that can be obtained from echocardiography are necessary to appropriately refer horses for these studies.

This research discusses how diagnostic ultrasound, particularly echocardiography, assists clinicians in identifying and quantifying various cardiac conditions in horses, including congenital and acquired cardiac lesions, septal defects, endocarditis, pericardial effusion, intracardiac shunting, cardiomegaly, and heart muscle failure.
Echocardiography Overview
- Echocardiography, a type of diagnostic ultrasound, provides images of the beating heart. This crucial imaging tool allows medical professionals to observe the heart in live motion, determining the heart’s specific measurements and evaluating its overall function.
- The study focuses on the usage of echocardiography in horses, indicating its necessity for appropriate referral of equine patients.
Types of Echocardiograms
- M-mode (motion) echocardiogram and two-dimensional echocardiogram are mentioned particularly in the study. These are complementary studies and are highly effective in identifying various cardiac conditions.
- M-mode echocardiography monitors the motion of the heart structures over time, which helps in analyzing the heart’s actual mechanical function.
- Two-dimensional echocardiography, on the other hand, provides a detailed image of the heart’s structure and movement in a two-dimensional plane. This offers comprehensive visual insights into the heart’s anatomy and function.
Identified Cardiac Conditions
- Echocardiography can identify specific congenital (existent from birth) and acquired (developed later in life) cardiac lesions. These could be abnormalities or diseases in the heart’s tissues or valves.
- It can spot cardiac septal defects, where there’s a hole in the wall (septum) that divides the heart’s upper or lower chambers. This defect can affect the heart’s ability to pump blood effectively.
- Endocarditis, an inflammation of the heart’s inner lining usually involving the heart valves, can be seen with echocardiography.
- Echocardiography also detects pericardial effusion, which is the accumulation of excess fluid in the sac-like covering surrounding the heart (pericardium), and intracardiac shunting, a condition where blood bypasses the regular circulatory route within the heart chambers or blood vessels.
- Cardiomegaly (enlargement of the heart) and heart muscle failure, indicating decreased ability of the heart muscle to pump blood, can be visualized and estimated using echocardiography as well.
Significance of Echocardiography
- Echocardiography is an essential tool in veterinary cardiology as it not only diagnoses the specific cardiac conditions in horses but also provides insights into the degree of cardiac compensation and muscle failure accompanying these conditions. This information aids in developing appropriate treatment strategies.
- Understanding how echocardiography works and the kind of information it can provide are vital for veterinary clinicians to make appropriate referrals for these studies and to evaluate the results.
