Epidemiology And Etiology Heart

Nearly five million Americans are afflicted with heart failure. ' Cardiac transplantation is one option for patients with severe congestive heart failure. Candidates for cardiac transplantation generally present with New York Heart Association (NYHA) class III or IV symptoms and have an ejection fraction of less than 20%. The general indications for cardiac transplantation include rapidly declining cardiac function and having a projected 1-year mortality rate of greater than 75%. Mechanical support with an implantable left ventricular assist device may be appropriate as bridge therapy

while patients await the availability of a viable organ. Indications for heart transplant include:

• Cardiomyopathy (i.e., dilated myopathy, hypertrophic cardiomyopathy, restrictive myopathy)

• Congenital heart disease

• Coronary artery disease

• Valvular heart disease

Most heart transplants are orthotopic; however, in certain situations, heterotopic cardiac transplants have been performed. There have been a handful of cardiac transplants that involved living donation. Although this seems strange, this occurs when one patient receives a simultaneous heart-lung transplant, but their native heart is well functioning and may be subsequently transplanted into another recipient. This procedure is referred to as a "domino" heart transplant. There were 1,852 heart transplant procedures done in 2009.
