What is the average life expectancy of having a left ventricular assist device?

Depends

It depends on the type of device (the newer devices HeartMate II and Heartware) have longer life expectancies and fewer complications than 1st generation LVADs. If an LVAD is placed as destination therapy people have lived as long as 7 years without having device replace or a complication...however this is the exception no the rule. Newer devices quote averages of about 5 years.

What is the average life expectancy after having a left ventricular assist device?

Depends

Lungs
When a person needs a VAD, life expectancy without it is short unless the VAD is placed. It all depends on the indication for the VAD,the status of the other ventricle and the lungs and if it is a bridge to transplant or destination therapy, or a bridge to a bridge to transplant. The 5 year survival for a heart transplant is about 70%.VAD recipients may suffer complications like stroke, bleeding,

Which is the average life expectancy after having a left ventricular assist device, or lvad installed?

LVAD

Lvad
Nowadays, 80–85% of patients are alive a year after having an LVAD fitted and 70–75% after two years. This is fantastic considering that many of them would only have had a life expectancy of 12 months or less before their LVAD treatment. One patient whom I know lived for 5.5 yrs (destination therapy).

Dr. Bennett Werner answered:

What is the life expectancy for people with Ventricular Tachycardia? How serious is Ventricular Tachycardia, and what kind of treatment is available?

Variable

Arrhythmia
VT has a wide spectrum of severity. Some kinds cause no symptoms and are benign and others deteriorate rapidly to ventricular fibrillation and cause death. In the setting of hypertrophic cardiomyopathy (your other question), VT is more serious and may require placement of an ICD. ICDs have been shown to greatly improve prognosis.

What is the use of a left ventricular assist device (LVAD)?

Advanced CHF

Lvad
Typically and LVAD has been used in the setting of a patient with advanced congestive heart failure (CHF) where the patient is being listed for or is awaiting a heart transplantation. More recently, LVAD's have been approved as destination therapy. On occasion we see patients who recover from their CHF through the use of an LVAD, but that is not very common. There are multiple LVAD types now.

Dr. Samuel S. Hahn answered:

Is bridging to transplantation with a left ventricular assist device a risky procedure?

Depends

Stroke
Like most of medicine and life, you have to balance relative risk vs absolute risk. The absolute risk of an LVAD is high (stroke, infection, death) but if the heart is really failing and a donor cannot be found, the relative risk of NOT doing an LVAD may be higher than putting one in. It all depends on the overall clinical circumstances.

Dr. Gavin Noble answered:

Does complete implantability reduce infection with the use of a left ventricular assist device?

Probably

Bacterial_infections
The next generation of completely implantable LVADs is not yet clinically widely available, so we don't know for sure yet. There will certainly be less infection from skin organisms transmitted through on the cables. However, there is still the chance that any bacteria that get in the bloodstream could infect the device since it is a foreign body.

What is left ventricular assist device?

Device, propel blood

Blood
It is a device that propels blood thus taking over the function of the weak and failing left lower heart chamber. It is typically implanted in patients with severe class 4 heart failure who would otherwise have little mobility or not survive due to the failing heart.
