About This Presentation

Description : Check out this medical PowerPoint presentation titled "APPROACH TO CYANOTIC CONGENITAL HEART DISEASE" by Punit Goel, MD.

This medical PowerPoint presentation talks about Cyanotic congenital heart disease (CCHD).

Cyanotic congenital heart disease (CCHD) is a group of heart defects that result in decreased oxygenation of the blood and can cause cyanosis, a bluish discoloration of the skin, lips, and nails.

The approach to CCHD typically involves a thorough evaluation of the patients medical history, physical examination, and diagnostic testing, such as echocardiography, electrocardiogram, and cardiac catheterization.

Treatment options for CCHD depend on the specific type and severity of the heart defect. In some cases, surgery may be necessary to repair or correct the defect. In other cases, medications may be used to alleviate symptoms and improve heart function.

It is essential to monitor and manage the patients oxygen levels, as well as any related medical conditions, such as anemia, that may exacerbate the symptoms of CCHD.

Lifelong follow-up with a healthcare professional who specializes in congenital heart disease is typically recommended to manage symptoms and monitor for potential complications. Newer therapeutic options like genetic therapy and stem cell therapy are under development and hold promise for future improvement in the management of CCHD.

Slide 1-

APPROACH TO CYANOTIC CONGENITAL HEART DISEASE Dr. R. Suresh Kumar Head, Department of Pediatric Cardiology
Slide 2-

Cyanosis Bluish discolouration of skin & mucous membranes due to increased concentration of reduced Hb >3g% ABG; >5g%CBG Causes— CNS, Musculoskeletal system, Airways, Alveolar-capillary membrane, Hb AND CVS. Central vs peripheral. Cardiac vs Respiratory. Peaceful cyanosis is cardiac
Slide 3-

Evaluation of the cyanotic baby Is the baby cyanosed? SpO2 will confirm. Is the cyanosis central/peripheral? Keep the baby warm. Is cyanosis cardiac? 1)Respiratory distress 2)Response to oxygen ABG - low pH, low pO2, Low pCo2 CxR-heart size & configuration, vascularity ECG Axis RV/LV dominance
Slide 4-

Cyanotic CHD-classification Reduced Pulmonary blood flow Tetralogy of Fallot/pulmonary atresia TOF-like physiology (complex congenital heart disease, large VSD PS/PA) Critical PS/ pul.atresia intact IVS Ebstein’s anomaly Low pAO2, oligaemic lungs, neonates respond to PGE1.
Slide 5-

Classification - Cyanotic CHD, Increased PBF Transposition of Great Arteries Total Anomalous Pulmonary Venous connection Single Ventricle Truncus Arteriosus DORV
Slide 6-

Clinical findings CCHD with decreased pulmonary blood flow Quiet precordium Single S2 Murmurs Ejection systolic murmur at the base No murmur Continuous murmur of PDA / collaterals ECG – RAD, RVH LV dominance in tricuspid atresia LAD in tricuspid atresia, AVCD with PS, Single ventricle with PS
Slide 7-

Clinical findings - 2 CCHD with increased pulmonary blood flow Mild cyanosis Active precordium Epigastric pulsations Congestive heart failure Single S2 (except in TAPVC) TGA Profound cyanosis Single S2 No murmur Normal / mildly increased lung vascularity on CXR
Slide 8-

Tetralogy of Fallot/P.Atresia Large VSD/ RVOT obstruction/atresia Cyanosis depends on degree of Obstruction, PDA/collaterals Neonates may need PGE1 to maintain saturation – needs urgent BT shunt. Progressive cyanosis/spells Total correction-around 1 yr.

Cyanotic Spells Rapid decrease in systemic oxygen saturation with hyperventilation  Convulsions, coma, death. Age : 6mon – 6 yrs. Cyanosis on crying is not a spell. Crying/exercise may trigger spells. Drop in SVR/ Inf.spasm  R to L shunt  acidosis  hyperventilation :vicious cycle

Cyanotic Spell- Treatment Knee chest position , Oxygen Morphine 0.1 mg/kg iv (sedation,resp dep.);Soda bicarb iv 1-2 ml/kg Increase SVR : Propranolol 0.1 mg/kg iv; Methoxamine 0.1 mg/kg iv; Phenylephrine 1-5mic.g/kg /min iv infusion. Ventilation. Paralyse Emergency surgery Propranolol for prophylaxis

Complex CHD,TOF-like physiology DORV PS/PA Presents like TOF. Needs neonatal BT shunt, if ductus-dependent. Total correction around 1 year, may need a homograft. Single Ventricle PS/PA. Presents like TOF. But 2-ventricle Repair not possible.Neonatal BT shunt, if needed. SVC to RPA anastomosis (Bidirectional Glenn) at 3-6months. IVC to PA connection (Lateral tunnel or Extra cardiac Fontan) at 2-5 yrs.

Slide 17-

Tricuspid Atresia Pulmonary blood flow depends on ASD, VSD, Pulmonary stenosis. May be increased / decreased / balanced. Cyanosis or heart failure predominant presentation accordingly. LV dominance and left axis in ECG helpful. Management in Fontan track.Neonatal BT shunt (for severe cyanosis) or PA banding (for heart failure) may be needed.

Critical PS PAIVS Cyanosis on day 1. Pulmonary circulation ductus dependent. RV normal or in a range of hypoplasia. If RV is adequate,catheter or surgical pulmonary valvotomy is the treatment. If RV is small, BT shunt. May need both. Further management may be - Glenn + Pulm. Valvotomy (1½ ventricle) or staged Fontan, when 2-ventricle repair not possible. Myocardial sinusoids / RV dependent coronary circulation - adverse prognosis.

Ebstein’s anomaly Inferior displacement of septal and inferior tricuspid leaflets. Thin RV. May have PS. Neonatal cyanosis may be severe. High PVRTR  R to L atrial shunt. Usually transient. Course:May be asymptomatic. Cyanosis, Rt heart failure and SVT may be problems. Surgery for severe cyanosis/heart failure.
Slide 25-

Ebstein’s anomaly History of SVT Generally good effort tolerance Cardiomegaly Multiple heart sounds (split S1, split S2, S3, S4) Scratchy systolic murmur at LLSB Cardiomegaly with huge RA on CxR. ECG-abnormal axis, RAE, polyphasic QRS. May have WPW syndrome

TGA with VSD No PS: Cyanosis minimal. CHF in a few weeks. Needs Arterial Switch operation in 3 months. Rapid progression of PVD, if untreated. TGA/VSD/PS: Cyanosis depends on degree of PS. BT shunt if cyanosis is severe. Rastelli operation at 3-5 yrs.
Slide 33-

TAPVC All 4 pulm veins join a common chamber which eventually reaches RA. Supracardiac- common chamber drains to innominate vein or to SVC. Cardiac- drains to coronary sinus or RA Infracardiac (Infradiaphragmatic). Descending vertical vein  portal vein  ductus venosus  IVC. Obstructed.

Persistent Truncus Arteriosus A single arterial trunk leaves the heart above a VSD. PA arises with a common trunk or as separate branches. CHF in a few weeks of life, mild cyanosis.
