Insights

A significant number of newborns with heart murmurs have congenital heart disease (CHD). Early detection and referral to a pediatric cardiologist are crucial for managing these critical pediatric cardiovascular conditions.

Area of Science:

  • Pediatrics
  • Cardiology
  • Neonatology

Background:

  • Congenital heart disease (CHD) represents the most prevalent form of pediatric cardiovascular disease.
  • Neonatal heart murmurs are a common clinical finding requiring careful evaluation.

Purpose of the Study:

  • To ascertain the prevalence of heart murmurs in newborns.
  • To investigate the correlation between neonatal heart murmurs and congenital heart disease (CHD).

Main Methods:

  • A 1-year cross-sectional study involving 2928 newborns in Ardebil, Iran.
  • Neonatal physical examinations were conducted to screen for heart murmurs.
  • Echocardiography was performed on all neonates identified with murmurs.

Main Results:

  • A heart murmur was detected in 91 (3.1%) neonates.
  • Congenital heart disease (CHD) was diagnosed in 47 (51.6%) of the neonates with murmurs.
  • Ventricular septal defect was the most frequent abnormality (17.6%), followed by patent ductus arteriosus (11%).

Conclusions:

  • Approximately 50% of newborns with heart murmurs were found to have congenital heart disease (CHD).
  • Close monitoring of neonates with murmurs is essential for timely diagnosis of CHD.
  • Early referral to pediatric cardiology services is recommended for neonates presenting with heart murmurs.

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Heart Sounds01:15

Heart Sounds

Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
Development of the Heart01:27

Development of the Heart

The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart tube by...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
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...
