1 Adults with Congenital Heart Disease Michael E. McConnell MD, Wendy Book MD Teresa Lyle RN NNP

2 Outline History of CHD Statistics Specific lesions (TOF, TGA, Single ventricle) Erythrocytosis Pregnancy

3 History of Congenital Heart Disease Surgery 1938 Closure of a patent arterial duct by Robert Gross (Boston) 1944 Repair of coarctation of the aorta by Clarence Crafoord (Sweden) 1945 Palliation of tetralogy of Fallot by Alfred Blalock (Baltimore) 1948 Opening of a stenotic mitral valve by Charles Bailey (Philadelphia)

4 History of Congenital Heart Disease Surgery (continued) 1952 Closure of an ASD using hypothermic cardiac arrest by F. John Lewis, Minneapolis 1954 Closure of a VSD using controlled cross circulation by Walt Lillehei, Minneapolis 1954 Repair of tetralogy of Fallot using controlled cross circulation by Walt Lillehei, Minneapolis

7 Adults with Congenital Heart Disease Over 1,000,000 adults with congenital heart disease living in North America 26,000 infants are born with CHD annually ~ 300 CHD patients in the Atlanta area reach adulthood each year

8 Adults with Congenital Heart Disease 50-75% have had corrective or palliative surgery ~30% will require additional surgery Many will have improved survival if cared for in a comprehensive adult CHD clinic

9 Adults with Congenital Heart Disease Pediatric cardiologists Internal medicine cardiologists with additional training in adults with congenital heart disease Med/Peds trained cardiologists EP/Surgeons/Interventional cardiologists/high risk OB/congenital cardiac anesthesiologists

35 Transposition of the Great Vessels Surgery for the failing right ventricle 11 patients with failing RV had PA Banding, plus one other who had PS 4 had reoperation to tighten the band 6 had ASO, 2 died 4 had biventricular failure and had transplantation 2 awaiting ASO Mavroudis C and Backer CL.

36 Single Ventricle LV angiography in a patient with tricuspid atresia and a very small right ventricle

37 Single Ventricle Right ventriculography in a patient with a dominant right ventricle and transposition

38 Single Ventricle Palliation

39 The Fontan operation is doomed to fail Dr. Andrew Reddington, American College of Cardiology Annual Meeting March 2003 At Egleston Children s Hospital we perform about 30 Fontan operations yearly The total number of adult heart transplants performed in Georgia in 2003 was 30.

40 Erythrocytosis NOT Polycythemia!!! A physiologic consequence of chronic hypoxia RBC s increased, WBC low normal, platelets low

41 Erythrocytosis (cont d) Compensated and Decompensated Compensated- High (stable) hematocrit, replete iron stores NO MAGIC NUMBER! Decompensated- an acute rise in Hct from baseline May be secondary to acute illnesspneumonia, sepsis

42 Erythrocytosis (cont d) Phlebotomy is RARELY indicated Erythrocytosis complications Microcytosis (usually iatrogenic) Increased uric acid production Cholelithiasis

43 Pregnancy Outcome depends on the lesion and the pre pregnancy symptom status Lesions usually associated with good outcomes Left to right shunts Valve regurgitation

44 Pregnancy (cont d) Lesions that generally do poorly with pregnancy Stenotic lesions (AS, PS, MS) Cyanotic patients Patients with pulmonary hypertension

45 Pregnancy (cont d) Results from Loyola Adult Congenital Heart Clinic (Dr. Frank Cetta) 106 women with 258 pregnancies No maternal mortality 2 pacemaker malfunctions 1 atrial fibrillation 1 SVT 1 balloon mitral valvuloplasty at 32 weeks

46 Pregnancy (cont d) 21% spontaneous abortions 14% premature deliveries 6 sets of twins 3 neonatal deaths

47 Pregnancy (cont d) Loyola 46 women told not to get pregnant 19 (41%) had a total of 44 pregnancies No maternal mortality 25% spontaneous abortions 16% premature births 1 neonatal death

48 Summary There are many adult patients with congenital heart disease Many will require additional surgery Long term complications often include dysrrhythmias and ventricular failure, but interventions are often unique to the population
