<s>[INST] What surgical options are there for a heart failure patient?
 [/INST] Device therapy helps in improving quality of life and life expectancy. CRT device helps in improving Ejection Fraction and decreases mortality. AICD device prevents sudden cardiac death. Both these devices can be implanted without anesthesia and require hospitalization for a couple of days. 

LVAD are devices that act as an artificial heart and are used in critically ill patients. Cardiac transplantation is another option that helps in removing the diseased heart and giving a healthy heart to the patient. Source: NARAYANA HEALTH .
