  2. Introduction

  3. Congestive Heart Failure

  4. !! Congestive heart failure occurs when the heart can no longer meet the metabolic demands of the body at normal physiologic venous pressures.

  5. !! Congestive heart failure in the fetus, or hydrops, can be detected by performing fetal echocardiography. !! Due to underlying anemia, arrhythmias ( supraventricular tachycardia), myocarditis or cardiomyopathy.

  6. !! Neonates and infants younger than age 2 months are the most likely group to present with congestive heart failure related to structural heart disease. !!Myocardial disease due to primary myopathic abnormalities or inborn errors of metabolism must be investigated.

  7. !!Respiratory illnesses, anemia, and known or suspected infection must be considered. !! Renal failure can result in CHF due to fluid retention and anemia.

  8. !! In older children, is caused by valvar or subvalvar aortic stenosis, coarctation, myocarditis, cardiomyopathy, hypertension, renal failure, arrhythmias or myocardial ischemia.

  9. Physical Examination !! Low cardiac output with hypotension !! Cool extremities & poor peripheral perfusion. !! Thready pulse . !! Decreased urine output.

  10. !! Tachycardia . !! Venous congestion : * Right-sided (hepatomegaly, ascites, abdominal pain, pleural effusion, edema, jugular venous distention) * Left-sided (tachypnea, retractions, nasal flaring or grunting, rales, pulmonary edema)

  11. !! Low cardiac output : Fatigue or low energy, pallor, sweating, cool extremities, nausea / vomiting, poor growth, dizziness, altered consciousness, and syncope

  12. Treatment & Management !! The goals of medical therapy include the following: • Reducing the preload. • Enhancing cardiac contractility. • Reducing the afterload. • Improving oxygen delivery. • Enhancing nutrition. • As

  13. !! Oral (PO) or IV diuretics eg, Furosemide, Thiazides or Metolazone. !! Dopamine, Dobutamine, Inamrinone or Milrinone. !! Digoxin appears to have some benefit

  14. !! Angiotensin-converting enzyme (ACE) inhibitors e g Captopril !! Serum potassium levels may be monitored, and supplementation should be provided

  15. !! Enhanced caloric content feedings and, in some cases, nasogastric or gastrostomy feedings may be necessary to maintain the patient's growth.

  16. !! Cardiac resynchronization therapy (CRT) has emerged as a useful therapy in the treatment. !! CRT involves use of biventricular pacemakers to improve ventricular function by electrically adjusting the timing of right & left ventricular contraction.
