What is an LVAD driveline infection?
Driveline infections (DLIs) are the most common type of LVAD-associated infection (LVADI). DLIs occur frequently because the driveline exit site creates a conduit for entry of bacteria and the prosthetic material of the driveline creates an ideal environment for the formation of bacterial biofilms (1).
Is an LVAD internal or external?
Managing an LVAD device LVADs are portable, meaning you can return home once it’s placed. However, it contains internal and external components. A surgeon places the pump in the chest and a tube connects the pump to a battery pack and control system outside the body.
What is a percutaneous driveline?
The percutaneous driveline is the most common site of infection in these patients and often serves as a portal to deeper pump infections. There are no data defining the role of prophylactic antibiotics in preventing these infections.
What is the most common complication of LVAD placement?
The most commonly encountered LVAD-related complication is bleeding. Up to 70% of LVAD patients will encounter a bleeding complication over the lifetime of the LVAD, although bleeding that requires surgical intervention is uncommon [5].
What is a driveline in medicine?
A tube passes from the device through the skin. This tube, called the driveline, connects the pump to the external controller and power source. The pump and its connections are implanted during open-heart surgery.

How often do you change LVAD dressing?
6) How long do we have to do the driveline dressing change? The driveline always requires a sterile dressing over the site. You or your caregiver will start out having to change it daily for approximately three months then you should be transitioned to a weekly change, as long as there are no issues with the site.
What is the difference between VAD and LVAD?
Although a VAD can be placed (implanted) in one or both ventricles of your heart, it is most frequently implanted in the left ventricle. When placed in the left ventricle, it’s called a left ventricular assist device (LVAD). Current LVADs provide a constant flow of blood from your heart to your body.
Which factors minimize the risk of driveline infection?
Results: Thirty-four studies focused on vulnerable host, portal of entry, and causative organism aspects of the Chain of Infection. Increased BMI, younger age, exposed driveline velour showed increased risk of infection and driveline dressing protocol change showed lower risk of infection.
How often should LVAD dressing be changed?
In both scenarios, dressing changes according to the standard of the implanting center 1–2 times weekly, photo documentation during dressing change and smear upon routine examination at the VAD outpatient clinic is recommended.
Left ventricular assist devices (LVADs) have revolutionized the treatment of advanced heart failure, but infection remains a substantial risk. LVAD driveline infections (DLIs) are the most common type of LVAD-associated infection (LVADI).
What is the PMCID of left ventricular assist device driveline infections?

What are the treatment guidelines for lvadis and DLI?
No comprehensive guidelines for treatment of LVADIs exist to date, though general guidelines for treatment duration proposed by Nienaber et al. suggest 2-4 weeks of antimicrobial therapy with or without surgical debridement for DLI.
