What is the diagnosis?
Provisional diagnosisA FT neonate with highly suspected CHD
antenatal diagnosis of cardiac problemRD and poor suckling since 2nd day of lifeEvident signs of hypoperfusion
laboratory investigationsABGs : PH 7.2 , PCO2 51, PO2 36 , sat 55%, HCO3 19, BE -9 CBC : Hb 15, WBC 14, PLT 63.000sugar 8 , ALT 396, AST 918, ALKP 438 , LDH 871 ,CHOL 91, TG 95, Ammonia 141 T.protein 7.3 , Albumin 3.5 , T.bil 21, D. bil 10 PT 40 ,INR 3 ,PTT 65 urea 130, CRE 0.8 , Uric acid 10 , Na 145, K 7.3 , Ca 7.4 ,Ph 7
Radiology Chest x ray: Cardiomegaly with bilateral lung infiltrations.U/S Abdomen : hepatomegaly U/S brain : normal ECHO : dilated Cardiomyopathy (secondary), normal heart structure , moderate contractility
Diagnosis
Cardiomyopathy complicated by: Heart failureHepatic failure Acute kidney injury Suspected mitochondrial disorders
Management
Cardiorespiratory stabilization and support Keep on MV Dopamine 10 mic /kg/minDobutamine 10mic /kg/min monitoring blood pressure
ManagementLiver support ADEK vitaminsUrsodeoxycholic acid Kept initially NPO,TPN 1g/kg intralipid and 1g/kg aminosol Then given pregestamil milkRandine , flagyl FFP
Management
Acute kidney injuryMeticulous attention to fluid input/outputDrugs adjusted to GFR
ManagementOther lines of managementAntibiotics given empirically to cover any possible sepsisRepeat blood transfusion as neededSymptomatic management: phenobarbitone added for development of seizures

Day 8 :Still in bad general condition Kidney function improved( urea 54, crea 0,5)Still on MCV ( dopamine and dobutamine )TPNDay 18:Start weaning from MCVDopamine and dobutamine 5mic CVS : irregular heart rate with bradycardia ECG was askedStart pregestamil milk
Day 20:Stop TPN Extubation from MCVStop dopamine CBC ; Hb 13, WBC 9,7 , PLAT 247ABGs ; PH 7,5 , PCO2 34, PO2 190 , sat 100%, HCO3 26, BE 4 (0N MCV)sugar 63 , urea 31, CRE 0,6 ,, Na 137, Cl 119, K 4 , Ca 10 , T.bil 12,5 D. bil 7,5

Further investigationsanti-SSA/Ro, anti-SSB/La were negativeTORCH: was asked but not done
Our final diagnosisDilated cardiomyopathyArrhythmiaCholestasis
Highly suspected IEM (Mitochondrial disorder)
Discharged to Rantisi Hospital after 31 days of admission On moderate general condition HR 100 RR 59 BP 97/60 SAT 99% ( room air)Digoxin 20 mic /12h poLasix 4mg /8h poCaptopril 1,5 mg /8h Ursodeoxycholic acid 40mg /8h poAdol 2 drop /24 poVit k 2mg /24 po

Diagnosis CARDIOMYOPATHY COMPLICATED BY AV BLOCk , AKI and CHOLESTASIS
NEONATAL CHOLESTASIS
DEFINITIONConjugated hyperbilirubinemia is defined as a conjugated bilirubin concentration greater than 2 mg/dL or more than 20% of total bilirubinProlonged elevation of the serum levels of conjugated bilirubin beyond the 1st 14 days of life

Is there association between arrhythmia and cholestasis??
Neonatal cholestasis associated with arrhythmia
ECG showing third degree heart block with atrioventricular dissociation and slow ventricular rate (atrial rate is 150, ventricular rate is 85 bpm).
Congenital heart block Congenital heart block is a rare disorder.It has an incidence of about 1 in 22,000 live births. neonatal lupusstructural heart disease(L TGA, AV canal defects )Many times, no clear etiology is determined for isolated CAVBThe prognosis for congenital complete heart block is usually favorable
