    Insights

    Pulsed tissue Doppler effectively evaluates systolic and diastolic function in pediatric heart failure patients. This method aids in assessing ventricular geometry and dysfunction in children with congenital heart disease.

    Area of Science:

    • Pediatric Cardiology
    • Echocardiography
    • Cardiovascular Physiology

    Background:

    • Two-dimensional (2D) and Doppler echocardiography are standard non-invasive methods for assessing ventricular function in children.
    • Congenital heart malformations can lead to congestive heart failure (CHF) in pediatric patients, affecting systolic and diastolic function.

    Purpose of the Study:

    • To evaluate systolic and diastolic ventricular function in pediatric patients using classical echocardiographic parameters and pulsed tissue Doppler.
    • To assess the correlation between these echocardiographic parameters in children with and without heart failure.

    Main Methods:

    • The study included 18 healthy children and 9 children with CHF secondary to congenital heart malformations.
    • Systolic and diastolic function parameters were measured using 2D echocardiography, M-mode, color Doppler, pulsed Doppler, and pulsed tissue Doppler at the mitral and tricuspid annulus.

    Main Results:

    • Patients with heart failure exhibited altered diastolic patterns (E wave velocity compared to A wave) and increased E wave deceleration time, indicating diastolic dysfunction.
    • Left ventricular flow propagation velocity (Vp) was decreased in heart failure patients; the E/Vp ratio remained constant due to concurrent changes in E wave velocity.
    • Significant associations were found between the severity of systolic and diastolic dysfunction in pediatric patients with congestive heart failure (Student test, p < 0.05).

    Conclusions:

    • Pulsed tissue Doppler measurements are valuable for evaluating pediatric patients with altered ventricular geometry due to congenital heart disease.
    • This technique aids in identifying systolic-diastolic dysfunction and heart failure in children.
    • Tissue Doppler provides a comprehensive assessment of ventricular function in complex pediatric cardiac conditions.

    Heart Failure II: Pathophysiology

    Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

    Imbalances in Cardiac Output01:26

    Imbalances in Cardiac Output

    The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
    CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

    Pathophysiology of Heart Failure01:17

    Pathophysiology of Heart Failure

    Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

    Cardiomyopathy II: Dilated Cardiomyopathy

    Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

    Mitral Regurgitation I: Introduction01:20

    Mitral Regurgitation I: Introduction

    Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
