2013 College of Diplomates of the American Board of Pediatric Dentistry Annual Meeting: pediatric cardiology: an overview.

Congenital heart defects can be classified as those characterized by a left to right shunt, a right to left shunt, obstruction to flow from the heart, or abnormalcies of myocardial contraction and relaxation. Left to right shunts include atrial and ventricular septal defects, and patent ductus arteriosus. Right to left shunts include transposition of the great arteries, tetralogy of Fallot, tricuspid atresia among others. These defects result in cyanosis. Lesions causing obstruction to blood flow from the heart include aortic and pulmonary valve stenosis and coarctation of the aorta. Disorders of myocardial contraction and relation include hypertrophic, dilated, and restrictive cardiomyopathies. In addition, the author will discuss innocent heart murmur and Kawasaki’s disease.
