Presentation Transcript

  1. Adult Congenital Heart Disease Carlos Macias, MD Arizona Pediatric Cardiology Consultants

  2. Congenital Heart Disease • An abnormality of the heart that is present at birth. It may be hereditary or due to some influence occurring during pregnancy.

  3. Congenital Heart Disease • 95% has no identifiable cause. • Ranges in severity from fairly simple to and curable to very complex and potentially lethal.

  4. Congenital Heart Disease • The most common birth defect. • Occurs in @ 1/100 births

  5. History of Congenital Heart Surgery • 1940’s-1950’s Maude Abbott and Helen Taussig defined the anatomy and physiology of Congenital Heart Disease. • Early 1950’s, first closed heart surgery using bathtub hypothermia. • 1953, First attempts at heart “bypass” surgery. • 1955, first bypass surgery at Mayo Clinic.

  6. Congenital Heart DefectsPrevalence • 32,000 new cases of CHD / year in the U.S. • 1.5 million, world wide. • 20,000 open-heart operations / year in U.S. • > 85% reaching adulthood • Approx.. 1,000,000 adults with CHD in U.S. • More adults than children with CHD

  7. Changes in Technology • Preoperative diagnosis • Intraoperative care (cardiopulmonary bypass). • Surgical technique • Postoperative care

  8. ACHD • For all but the most simple defects, surgical and catheter procedures are palliative rather that curative.

  9. Acyanotic CHD(left to right shunt) • Atrial septal defect (ASD) • Ventricular septal defect (VSD) • Endocardial cushion defect • Patent ductus arteriosus (PDA)

  10. Cyanotic CHD(right to left shunt) • Obstruction to pulmonary blood flow • Tricuspid, pulmonary atresia • Intracardiac mixing of oxygenated and unoxygenated blood • Tetralogy of Fallot • Transposition of the great Vessels • Single ventricle

  11. Obstructive Valvar Lesions • Pulmonary valve stenosis • Aortic valve stenosis. • Coarctation of the thoracic aorta

  12. Fetal Circulation

  14. Atrial Septal Defect

  15. Atrial Septal Defects(View from right side)

  16. Atrial Septal DefectPatch Repair

  17. Amplatzer Occlusion of Atrial Septal Defect Clockwise from above: Transcatheter delivery of Amplatzer device, which is positioned across the atrial septal defect Left: Amplatzer device in place

  18. ASD, Survival Patterns • Normal, if closed before 20 years of age. • Good, but shorter than normal 25-41 yrs. • Increased morbidity and mortality after 41 yrs.

  19. ASD and PHT • Occurs in two chronologically disparate age groups. • Females, late teens and 20s. • Primary PHT with coincidental ASD • Don’t close the ASD !! • Patients > 40 years of age • Mild to mod. PHT secondary to longstanding left to right shunt. • Likely to benefit from ASD closure

  20. Ventricular Septal Defect VSD before surgical repair VSD after surgical repair
