Study Notes

Atrial Septal Defect (ASD)

Shortness of breath, especially when exercising, is a common symptom
Fatigue, swelling of legs, feet, or abdomen, heart palpitations, and skipped beats are other symptoms
Heart murmur, a whooshing sound, can be heard through a stethoscope
Treatment depends on the size of the hole in the heart
Small ASDs may close spontaneously, while others may not require surgery
Medications like beta blockers and anticoagulants may be used to manage symptoms
Surgery to close the defect is usually done electively between 1 and 3 years of age
Catheter-based repair uses a mesh patch or plug to close the hole
Open-heart surgery may be necessary for primum, sinus venosus, and coronary sinus atrial defects

Complications of ASD

Right-sided heart failure
Heart rhythm abnormalities (arrhythmias)
Increased risk of stroke
Shortened life span
Less common complications include Eisenmenger syndrome, which is a type of pulmonary hypertension

Patent Ductus Arteriosus (PDA)

The ductus arteriosus is essential for maintaining fetal systemic perfusion before delivery
It is a type of congenital heart defect

Tetralogy of Fallot (TOF)

Symptoms include high degree of cyanosis, polycythemia, severe dyspnea, growth restriction, and clubbing of the fingers
Children with TOF may assume a squatting or knee-chest position when resting
Management includes oxygen administration, small and frequent meals, and limiting strenuous activities
Corrective surgery is necessary to prevent growth and development restriction

Surgery Management for TOF

Temporary surgery includes Blalock-Taussig shunt and Waterston shunt
Permanent surgery involves full repair to relieve pulmonary stenosis and patching the ventricular septal defect (VSD)

Complications of TOF

Pulmonary hypertension
Infectious endocarditis

Disorders with Obstruction to Blood Flow

Obstructive defects include pulmonary stenosis, aortic stenosis, and coarctation of the aorta

Pulmonary Stenosis

Symptoms include cyanosis, heart murmur, chest pain, and shortness of breath
Treatment options include balloon dilation, valvuloplasty, valvotomy, valvectomy, and pulmonary valve replacement

Aortic Stenosis

It is a narrowing of the aortic valve opening, restricting blood flow from the left ventricle to the aorta
Symptoms include a typical murmur, faint pulses, hypotension, tachycardia, and inability to suck for long periods
Causes include congenital heart defect, bicuspid aortic valve, calcium buildup on the valve, and rheumatic fever
