    Study Notes

    Cyanotic Congenital Heart Defects

    • Cyanotic congenital heart defects result in cyanosis, visible bluish discoloration of the skin due to deoxygenated blood entering systemic circulation.
    • These defects are characterized by right to left shunts, where deoxygenated blood from the right side of the heart is shunted to the left side.

    Tetralogy of Fallot (ToF)

    • Composed of four critical components:
      • Ventricular Septal Defect (VSD): A hole between the ventricles.
      • Right Ventricular Hypertrophy (RVH): Thickening of the right ventricle muscle.
      • Pulmonary Stenosis: Narrowing of the pathway from the right ventricle to the pulmonary artery.
      • Overriding Aorta: Aorta positioned above both ventricles.
    • Risk Factors: Associated with DiGeorge syndrome, which is a deletion on the 22nd chromosome affecting thymus, parathyroid, and heart development.
    • Clinical Features:
      • Presents with cyanosis, particularly during exertion, crying, or feeding (termed "tet spells").
      • Heart auscultation reveals absent P2 sound due to insufficient blood flow through pulmonary valve and a systolic ejection murmur at the left upper sternal border.
    • Diagnostic Tests:
      • Chest X-ray: Shows a characteristic "boot-shaped" heart.
      • EKG: Commonly indicates right axis deviation.
      • Echocardiogram: Definitive test showing all four components of ToF.
    • Management:
      • Immediate measures for tet spells: calming, squatting position to increase systemic vascular resistance, administering oxygen, morphine, and beta blockers.
      • Long-term management requires surgical interventions such as patching the VSD and relieving pulmonary stenosis.

    Transposition of the Great Arteries (TGA)

    • Involves the aorta emerging from the right ventricle and pulmonary artery from the left, leading to two separate circulatory systems with no mixing of oxygenated and deoxygenated blood.
    • Risk Factors: Similar to ToF, connected to DiGeorge syndrome and maternal diabetes.
    • Clinical Features:
      • Severe cyanosis due to systemic circulation receiving deoxygenated blood.
      • Patients exhibit rapid breathing (tachypnea) due to low oxygen levels.
      • Heart auscultation might show a loud, single S2 with no murmur.
    • Diagnostic Tests:
      • Chest X-ray: Appears as an "egg on a string."
      • Echocardiogram: Reveals abnormal artery connections (aorta from right ventricle).
    • Management:
      • Atrial Septostomy: Creation of an ASD to allow mixing of blood.
      • Use of Prostaglandin E1 to keep the patent ductus arteriosus (PDA) open for blood shunting.
      • Surgical correction eventually required to re-establish normal blood flow paths.

    Truncus Arteriosus

    • A single arterial trunk arises from both ventricles that bifurcates into the pulmonary arteries and aorta.
    • Associated Conditions: Also linked with DiGeorge syndrome.
    • Clinical Features:
      • Results in mixed blood flow leading to cyanosis; oxygenated and deoxygenated blood combine.
      • Increased pulmonary blood flow due to excessive blood diverted to the pulmonary circulation.
    • Management: Surgical intervention required to separate pulmonary and systemic circulation, addressing the VSD concurrently.### Left Heart Failure in Infants
    • Excessive blood flow into the left heart can lead to left-sided heart failure in infants.
    • Pulsatile pulmonary flow increases strain on the heart; can cause pulmonary hypertension.
    • Clinical features include a systolic ejection murmur and a single S2 due to a single trunk for blood ejection.

    Diagnostics for Left Heart Failure

    • Chest X-ray reveals increased pulmonary blood flow and cardiomegaly.
    • Both left and right ventricles may show hypertrophy on an EKG due to volume overload.
    • Echocardiogram is the definitive test, showing a single trunk arising from both ventricles.

    Management of Left Heart Failure

    • Surgical intervention is critical within the first few weeks of life.
    • Minimal cyanosis is present due to partially mixed blood.
    • Medical therapy focuses on reducing pulmonary congestion with positive pressure ventilation and diuretics.

    Total Anomalous Pulmonary Venous Return (TAPVR)

    • In TAPVR, pulmonary veins do not connect to the left atrium; they drain into the right atrium via connecting veins.
    • Three main types: supracardiac, cardiac, and infracardiac.
    • Supracardiac type involves a connection from pulmonary veins to the superior vena cava.

    Clinical Picture of TAPVR

    • Severe cyanosis due to no oxygenated blood entering the left atrium.
    • Pulmonary veins experience obstruction; leads to pulmonary congestion and edema.
    • Symptoms include respiratory distress, tachypnea, and systemic hypoxemia.

    Auscultatory Findings in TAPVR

    • Systolic ejection murmur and split S2 due to increased blood flow to the right heart.
    • Diastolic rumble due to increased blood flow across the tricuspid valve.

    Diagnostic Findings for TAPVR

    • Chest X-ray shows increased pulmonary blood flow and "snowman sign."
    • Right atrial enlargement and right ventricular hypertrophy may be observed on EKG.
    • Definitive diagnosis via echocardiogram showing the connecting veins and obstructed pulmonary veins.

    Treatment for TAPVR

    • Surgical intervention is urgent and must happen immediately after birth to re-establish normal pulmonary venous return.

    Tricuspid Atresia

    • Defined as an absent or abnormally developed tricuspid valve, often accompanied by a hypoplastic right ventricle.
    • Associated defects may include a ventricular septal defect (VSD) and an atrial septal defect (ASD).

    Clinical Presentation of Tricuspid Atresia

    • Presents with severe cyanosis due to obstruction from right atrium to right ventricle.
    • Mixing of oxygenated and deoxygenated blood occurs, complicating systemic oxygenation.

    Auscultatory Findings in Tricuspid Atresia

    • Holosystolic murmur at the left lower sternal border due to VSD.
    • A single S2 reflects the absence of distinct valve components.

    Diagnostic Findings for Tricuspid Atresia

    • Chest X-ray shows decreased pulmonary vascularity due to compromised blood flow.
    • EKG may show non-specific abnormalities like left axis deviation.
    • Echocardiogram reveals the absence of the tricuspid valve, hypoplastic right ventricle, and associated defects.

    Management of Tricuspid Atresia

    • Creation of an ASD is necessary for survival; balloon atrial septostomy may be performed.
    • Maintaining an open patent ductus arteriosus (PDA) via prostaglandin E1 infusion is crucial for adequate pulmonary flow.### Cardio Respiratory Support Surgical Management
    • Surgical intervention is critical for managing certain congenital heart conditions.
    • Fontan procedure is often indicated for patients requiring immediate surgical treatment.

    Epstein Anomaly

    • Characterized by an enlarged right atrium and inferiorly displaced tricuspid valves, leading to a significant risk of obstruction.
    • Often associated with atrial septal defect (ASD).
    • Maternal lithium use is a key risk factor for this condition.
    • Symptoms typically present in adolescence or adulthood, primarily manifesting as cyanosis due to mixed blood flow.
    • Inferiorly displaced tricuspid valves block blood flow to the pulmonary artery, causing right-to-left shunting through the ASD.
    • Increased blood flow from the right ventricle back to the right atrium exacerbates left heart overload, potentially leading to heart failure and pulmonary edema.

    Clinical Presentation of Epstein Anomaly

    • Cyanosis is evident due to mixing of oxygenated and deoxygenated blood.
    • Possible findings include a holosystolic murmur from tricuspid regurgitation.
    • S3 and S4 heart sounds may be present due to rapid ventricular filling and elevated left atrial pressures.

    Diagnostic Tests for Epstein Anomaly

    • Chest X-ray reveals decreased pulmonary blood flow and an enlarged right atrium.
    • EKG may show Wolf-Parkinson-White syndrome Type B due to electrical conduction issues.
    • Echocardiography is the definitive test, illustrating atrial enlargement and structural abnormalities.

    Management of Epstein Anomaly

    • Maintaining patency of the patent ductus arteriosus (PDA) is crucial for adequate pulmonary blood flow using prostaglandin E1.
    • Pulmonary vasodilators (e.g., nitric oxide, milrinone) may be administered to lower pulmonary vascular resistance.
    • Surgical intervention is necessary in severe cases.

    Hypoplastic Left Heart Syndrome

    • Defined by underdevelopment of the left ventricle and its outflow tract, leading to significant structural heart issues.
    • Associated with abnormalities in the mitral and aortic valves.
    • Clinical presentation typically emerges a few weeks post-birth, especially after ductal closure.
    • Cyanosis results from impaired left ventricular function and obstructed systemic blood flow, leading to cardiogenic shock.

    Clinical Features of Hypoplastic Left Heart Syndrome

    • Symptoms include cyanosis due to poor systemic arterial blood flow.
    • Cardiogenic shock may occur due to reduced cardiac output and resulting hypotension.
    • Auscultation may reveal a single S2 sound with minimal murmurs due to compromised aortic flow.

    Diagnostic Tests for Hypoplastic Left Heart Syndrome

    • Chest X-ray typically shows increased pulmonary vascularity from right-to-left shunting.
    • EKG may present right axis deviation due to right heart volume overload.
    • Echocardiography is crucial for visualizing anomalies such as the hypoplastic left heart structures and potential ASDs.

    Management of Hypoplastic Left Heart Syndrome

    • Keeping the PDA open is essential to maintain some systemic blood flow using prostaglandin E1.
    • Timely surgical interventions are needed; in some cases, heart transplantation may be required for severe presentations.

    Cyanotic Congenital Heart Defects

    • Cyanotic defects cause cyanosis, indicating deoxygenated blood is circulated systemically.
    • Characterized by right to left shunts, deoxygenated blood escapes the heart's right side to the left side.

    Tetralogy of Fallot (ToF)

    • Composed of four features:
      • Ventricular Septal Defect (VSD): Hole between ventricles.
      • Right Ventricular Hypertrophy (RVH): Thickened right ventricle.
      • Pulmonary Stenosis: Narrowing between right ventricle and pulmonary artery.
      • Overriding Aorta: Aorta positioned directly above both ventricles.
    • Associated with DiGeorge syndrome linked to a 22nd chromosome deletion.
    • Symptoms include exertion-related cyanosis known as "tet spells."
    • Heart sounds include absent P2 and a systolic ejection murmur at the left upper sternal border.
    • Chest X-ray shows a "boot-shaped" heart; EKG often reveals right axis deviation.
    • Echocardiogram confirms the diagnosis.
    • Management of tet spells involves calming techniques, positioning, and medications; surgical correction includes VSD patching.

    Transposition of the Great Arteries (TGA)

    • Characterized by separation of circulatory systems, with the aorta from the right ventricle and pulmonary artery from the left.
    • Risks include maternal diabetes and DiGeorge syndrome.
    • Presents with severe cyanosis and rapid breathing due to low oxygen levels; heart auscultation reveals a loud single S2.
    • Chest X-ray appears as "egg on a string"; echocardiogram shows abnormal artery connections.
    • Management involves creating an Atrial Septostomy and administration of Prostaglandin E1 to keep the ductus arteriosus open, with eventual surgical correction needed.

    Truncus Arteriosus

    • A single arterial trunk arises from both ventricles, bifurcating into pulmonary arteries and aorta.
    • Associated with DiGeorge syndrome.
    • Clinical presentation includes cyanosis from mixed blood flow and increased pulmonary blood flow.
    • Requires surgical intervention to separate circulatory paths and fix VSD.

    Left Heart Failure in Infants

    • Excessive blood flow can lead to left-sided heart failure.
    • Symptoms include pulmonary hypertension and a systolic ejection murmur.
    • Chest X-ray shows increased pulmonary blood flow; EKG may indicate hypertrophy.
    • Echocardiogram identifies a single trunk from the ventricles.
    • Requires early surgical intervention; medical therapy focuses on reducing pulmonary congestion.

    Total Anomalous Pulmonary Venous Return (TAPVR)

    • Pulmonary veins drain into the right atrium instead of the left, categorized into supracardiac, cardiac, and infracardiac types.
    • Severe cyanosis occurs due to the absence of oxygenated blood in the left atrium.
    • Symptoms comprise tachypnea, respiratory distress, and systemic hypoxemia.
    • Chest X-ray reveals increased pulmonary blood flow, often showing the "snowman sign"; echocardiogram identifies abnormalities.
    • Urgent surgical intervention after birth restores normal venous return.

    Tricuspid Atresia

    • Characterized by absence or abnormal development of the tricuspid valve involving a hypoplastic right ventricle.
    • Commonly associated with VSD and ASD.
    • Symptoms include severe cyanosis due to mixing of blood from right atrium to ventricle.
    • Auscultatory findings include a holosystolic murmur from VSD and a single S2.
    • Chest X-ray indicates decreased pulmonary vascularity; echocardiogram confirms crucial defects.
    • Treatment involves creating an ASD and maintaining a patent ductus arteriosus using prostaglandin E1.

    Cardio Respiratory Support Surgical Management

    • Immediate surgical intervention is necessary for certain congenital heart conditions.
    • The Fontan procedure is often indicated for those needing urgent surgical care.

    Epstein Anomaly

    • Defined by an enlarged right atrium and inferiorly displaced tricuspid valve, increasing obstruction risk.
    • Frequently associated with atrial septal defects and linked to maternal lithium exposure.
    • Symptoms appear in adolescence or adulthood, manifested primarily as cyanosis.
    • Auscultatory findings may include a holosystolic murmur and S3/S4 heart sounds.
    • Chest X-ray shows an enlarged right atrium; echocardiography is definitive.

    Hypoplastic Left Heart Syndrome

    • Involves underdevelopment of the left ventricle and its outflow tract, leading to major structural heart issues.
    • Symptoms typically arise a few weeks post-birth; results in cardiogenic shock and cyanosis.
    • Auscultation may reveal a single S2 sound with minimal murmurs.
    • Diagnostics show increased pulmonary vascularity, especially on chest X-ray; EKG hints at right axis deviation.
    • Maintaining PDA open with prostaglandin E1 is crucial, and surgical interventions are often necessary, possibly including transplantation.

    Cyanotic Congenital Heart Defects

    • Cyanotic defects cause cyanosis, indicating deoxygenated blood is circulated systemically.
    • Characterized by right to left shunts, deoxygenated blood escapes the heart's right side to the left side.

    Tetralogy of Fallot (ToF)

    • Composed of four features:
      • Ventricular Septal Defect (VSD): Hole between ventricles.
      • Right Ventricular Hypertrophy (RVH): Thickened right ventricle.
      • Pulmonary Stenosis: Narrowing between right ventricle and pulmonary artery.
      • Overriding Aorta: Aorta positioned directly above both ventricles.
    • Associated with DiGeorge syndrome linked to a 22nd chromosome deletion.
    • Symptoms include exertion-related cyanosis known as "tet spells."
    • Heart sounds include absent P2 and a systolic ejection murmur at the left upper sternal border.
    • Chest X-ray shows a "boot-shaped" heart; EKG often reveals right axis deviation.
    • Echocardiogram confirms the diagnosis.
    • Management of tet spells involves calming techniques, positioning, and medications; surgical correction includes VSD patching.

    Transposition of the Great Arteries (TGA)

    • Characterized by separation of circulatory systems, with the aorta from the right ventricle and pulmonary artery from the left.
    • Risks include maternal diabetes and DiGeorge syndrome.
    • Presents with severe cyanosis and rapid breathing due to low oxygen levels; heart auscultation reveals a loud single S2.
    • Chest X-ray appears as "egg on a string"; echocardiogram shows abnormal artery connections.
    • Management involves creating an Atrial Septostomy and administration of Prostaglandin E1 to keep the ductus arteriosus open, with eventual surgical correction needed.

    Truncus Arteriosus

    • A single arterial trunk arises from both ventricles, bifurcating into pulmonary arteries and aorta.
    • Associated with DiGeorge syndrome.
    • Clinical presentation includes cyanosis from mixed blood flow and increased pulmonary blood flow.
    • Requires surgical intervention to separate circulatory paths and fix VSD.

    Left Heart Failure in Infants

    • Excessive blood flow can lead to left-sided heart failure.
    • Symptoms include pulmonary hypertension and a systolic ejection murmur.
    • Chest X-ray shows increased pulmonary blood flow; EKG may indicate hypertrophy.
    • Echocardiogram identifies a single trunk from the ventricles.
    • Requires early surgical intervention; medical therapy focuses on reducing pulmonary congestion.
