Trends In Healthcare: The Use Of Artificial Heart Devices To Treat Heart Disease Presented By: Justine Lighthall

Objectives • Describe different device types of devices • Define the types of therapy the Artificial Heart Device is used for. • Identify disease processes that rely on the use of the device. • State Statistics regarding the Artificial Heart Device • Explain how the device works

Objectives cont. • Identify hardware and software parts of the artificial heart device. • Describe Information System • Describe advantages and disadvantages of the Artificial Heart Device • Identify Ethical Issues

Objectives Cont. • State Informatics Competencies • Describe the functions and responsibilities of Informatics nurse • Trend summary

Device Types • Thoratec • Ventra assist • Heart Mate 1 • Heart Mate 2 • Abiomed

Types of Therapy • Destination Therapy: When one is not a candidate for transplant. • Non- Functional from CVA • Does not wish to be Transplanted • Bridge To Transplant: Temporary until listed and called for Transplantation. • Heart failure to severe to wait for heart transplant. • Recovery: Heart function is returned • Post-Partum • Viral Infections

Statistics • Heart Failure is the leading cause of death • An estimated sixty-two million people are suffering from congestive heart failure • FDA: Food and Drug Administration • FDA has approved a partial artificial heart. • FDA approval in April 2008 as a bridge-to-transplantation (BTT) treatment option for patients

LVAD Hardware • Internal Components • Inflow Cannula from left ventricle • Pump • Outflow Cannula to the Aorta • External Components • Battery Pack • Systems Controller • Driveline

LVAD Software • Each company has their own system software • Ventraview • Each software has similar components • Ability to record memory • Projects a constant flow of heart function • Stores a database of numbers pertaining to function of VAD

Components of Software • Flow • Speed • Pulsatile Index • Memory

Usability of Software • Efficient in maintaining patients lives • Provides satisfaction • Easy for patients to learn and control • Minimal error

Information System • The LVAD disseminates data to a control panel • Data is displayed on an LCD screen • The data describes the function of the heart and the device.

Information System • The Information System provides data for health care personnel • Physicians • Nurses • Engineers • Patients • The Information System describes function of the heart and device setting • Pump output • Speed • Power • PI • OI

Functions of Information System • Provide data that is used to treat the patient • Describes how the pump is working • Ability to record alarms

Information System Data Standards • The FDA ( Food and Drug Administration) • JCAHO ( Joint Commission ) • Intermacs • IRB ( Institutional Review Board )

Advantages • Advantages for an Artificial Heart Device • Used for treatment of end-stage heart failure. • Used in assistance while waiting for heart transplant. • Used for temporary use while waiting for heart recovery.

Disadvantages • Risk for major complications • Death • Stroke • Renal Failure • DVT/PE • Debilitation

Ethical Issues • Criteria • Age • Socio- economic status • Social Support • Transplantation

Informatics Competencies • Specialized VAD classes must be completed by all health care professionals. • Written test must be completed • Clinical experience and orientation • Demonstration of ability to care for the patient a VAD

Functions and Responsibilities of Informatics Nurse • Assessment of patient with VAD • Ability to identify complications of device • Utilizes knowledge on hardware and software of VAD

Summary • State of the Art technology • Augmentation of ventricles • Dissemination of Knowledge • User friendly Hamby. 2007
