Study Notes
Congenital Heart Disease (Part 1)
- Heart starts as a simple tube, formed by the fusion of mesodermal cells
- Endocardial cells in the middle complete the ventricular septum and valves
- In the 3rd week of gestation, simple tubes contract like an adult heart.
- This contraction and looping happen in the 4th week of fetal life, forming the primitive right and left ventricles and great arteries.
- An atrial septum forms, migrating downwards and leaving a space at the top (primum septum)
- A secondary membrane forms to the right of the primary membrane, creating an opening called the foramen ovale.
- Completion of the structures occurs from the second to third month of development
- Any insult to the heart's development during the first trimester can cause congenital heart disease (CHD)
- The maternal infection (e.g. COVID, German measles) during the first trimester can affect development, leading to CHDs in the baby.
Congenital Heart Disease (Part 2)
- Acyanotic CHD can be volume overload or pressure overload. Pressure overload includes PA stenosis, AV stenosis, and coarctation of aorta.
- Cyanotic CHD has increased or decreased pulmonary blood flow.
- Examples of Acyanotic CHD: Atrial Septal Defect (ASD), Patent Ductus Arteriosus (PDA), and Tetralogy of Fallot (TOF)
- Examples of Cyanotic CHD: Transposition of the Great Arteries (TGA) and total anomalous pulmonary venous return (TAPVR).
- Physical examination (PE) is crucial; PE findings include characteristics, such as murmurs and possible heart-related abnormalities.
- ECG can show ventricular hypertrophy, useful in evaluating patients with CHD.
- Chest x-rays can show abnormal heart or great vessel sizes.
- Imaging using 2D echocardiogram is vital to evaluate the anatomy and function of the heart and measure gradients.
- Treatment often requires surgery, especially for obstructed heart conditions.
- CHDs are categorized as acyanotic (with normal oxygen levels) or cyanotic (with abnormal oxygen levels). Acyanotic or cyanotic classification can be further divided based on volume or pressure overload.
- The presence or absence of cyanosis often aids in categorizing CHD.
Review of Normal Circulation
- Blood flow in utero is initially a single tube that divides into the aorta and pulmonary artery.
- Oxygenated blood from the placenta mixes with deoxygenated blood from the inferior, middle, and superior vena cava.
- 50% of blood from the placenta goes to the liver, the rest goes to the heart.
- Blood from the vena cava mixes with placental blood in the right atrium.
- Blood mostly flows through the foramen ovale into the left atrium.
- When the baby is born, umbilical cord clamping causes a change; flow to the lungs increases, and blood flow through the Ductus arteriosus (DA) and ductus venosus (DV) stops.
- Mean pressure of the left ventricle is equal to the pressure in the left atrium.
- Blood pressure of the pulmonary artery is 20-25% of the aortic pressure.
Acquired Heart Diseases in Children
- Rheumatic heart disease (RHD) is caused by group A streptococcal (GABHS) infection.
- RHD risk is high in children who have had strep throat.
- Diagnosis is based on presenting symptoms like fever, sore throat, and swollen lymph nodes.
- Patients with suspected RHD require 10 days of penicillin to prevent complications.
- Kawasaki disease (KD), is an acute systemic vasculitis characterized by fever and inflammation in blood vessels.
- The exact cause of KD is unknown, but viral infections, genetic predisposition, and environmental factors are considered potential causes.
- IVIG therapy followed by aspirin is standard treatment for KD.
