How LVADs Work
ثبت نشده
چکیده
Left ventricular assist devices have become an established treatment for patients with advanced heart failure, as a bridge to transplantation or recovery, or as a long-term option for those who are not candidates for cardiac transplantation (destination therapy). Although studies have clearly shown that LVADs can signifi cantly improve quality of life for patients, there are substantial risks associated with these devices. Careful patient selection for LVAD implantation may help to prevent signifi cant potential risks and complications, as well as to improve the effi cacy of these procedures.

How effective are continuous flow left ventricular assist devices in lowering high pulmonary artery pressures in heart transplant candidates?
BACKGROUND Pulmonary hypertension (PH) is considered a risk factor for morbidity and mortality in patients undergoing heart transplantation. Medical therapy with oral and pharmacologic agents is not always effective in reducing pulmonary artery (PA) pressures. Left ventricular assist devices (LVADs) have been used to reduce PA pressures in cases of PH unresponsive to medical therapy. METHODS ...
متن کاملCost-effectiveness of left ventricular assist devices (LVADs) for patients with advanced heart failure: analysis of the British NHS bridge to transplant (BTT) program.
BACKGROUND A previous cost-effectiveness analysis showed that bridge to transplant (BTT) with early design left ventricular assist devices (LVADs) for advanced heart failure was more expensive than medical management while appearing less beneficial. Older LVADs were pulsatile, but current second and third generation LVADs are continuous flow pumps. This study aimed to estimate comparative cost-...
