Overview
Patients requiring a cardiac transplant are generally with advanced, irreversible heart failure with a severely limited life expectancy. These patients would have failed medical and device therapy. Common indications include causes that led to this like- systolic heart failure with a left ventricular ejection fraction less than 35%, ischemic coronary artery disease with refractory angina, intractable life-threatening arrhythmias, cardiomyopathies, and congenital heart disease.
Indications
In order for a patient to be recommended for a heart transplant they will generally have advanced, irreversible heart failure with a severely limited life expectancy.[1] It is important to note that the life expectancy of heart failure has improved over the past two decades due to improvements in both medical therapy (ACE Inhibition, beta-blockers, aldosterone antagonists and device therapy such as automatic implantable cardiac defibrillators AICDs and cardiac resynchronization. Thus, patients should not be considered for cardiac transplantation unless they have failed aggressive medical and device therapy. [2][3]
Systolic Heart Failure with a Left Ventricular Ejection Fraction less than 35%[4]
Due to either:
- Ischemic cardiomyopathy
- Dilated cardiomyopathy
- Valvular heart disease
- Hypertensive heart disease
- Etiologies which are excluded are amyloid, HIV, and cardiac sarcoma
Ischemic Coronary Artery Disease with Refractory Angina
- Ischemia which is not amenable to percutaneous or surgical revascularization (coronary artery bypass graft surgery CABG) and is refractory to maximally tolerated medical and/or device therapy. [5]
Intractable life-threatening Arrhythmias
- Ventricular arrhythmias which are not controlled by an implantable cardioverter-defibrillator and are refractory or not amenable to electrophysiologic guided single or combination medical therapy
- Patients that are not a candidate for catheter ablation therapy. [2]
Cardiomyopathies
- Restrictive and Hypertrophic Cardiomyopathies with NYHA Class IV heart failure symptoms that persist despite maximal medical therapy, myomectomy, alcohol septal ablation, mitral valve replacement
- Non-dilated cardiomyopathies such as arrhythmogenic right ventricular cardiomyopathy. [2]
Congenital Heart Disease
- CHD resulting in New York Heart Association functional class IV Heart Failure not amenable to surgery.
- Severe symptomatic cyanotic congenital heart disease.
- Presence of some degree of pulmonary hypertension with the potential risk of developing fixed and irreversible elevation of pulmonary vascular resistance (PVR) [6]
