HTA of MDs
Health Technology Assessment of Medical Devices

HTA is multi-disciplinary field of policy analysis that examines the medical, economic, social and ethical implications of the incremental value, diffusion and use of a health technology in health care.

The term Health Technology refers to application of organised knowledge and skills in the form of devices, medicines, vaccines, procedures and systems developed to solve a health problem and improve quality of life.

Transcatheter Aortic Valve Implantation (TAVI) in Patients at Intermediate Surgical Risk

Transcatheter aortic valve implantation (TAVI), also referred to as transcatheter aortic valve replacement (TAVR), is the deployment of a bioprosthesis in the aortic valve using a catheter. In contrast to traditional open-heart surgery (i.e. surgical aortic valve replacement, SAVR), the procedure is minimally invasive when performed through transfemoral access and can be performed with light sedation […]

Bilateral Cochlear Implantation: A Health Technology Assessment

Sensorineural hearing loss is a condition in which the cochlea (the hearing organ in the ear) or the nerve pathways for hearing are damaged. A cochlear implant is a device that acts in place of the damaged inner ear to help communicate sound to the brain. At present, the Ontario government funds one cochlear implant for people who have hearing […]

Subcutaneous implantable cardioverter defibrillator (ICD)

Cardiovascular disease is a major public health issue accounting for almost 17 million deaths per year globally. According to estimates, 40-50% of them are sudden cardiac deaths. Approximately 6 million sudden cardiac deaths are caused by ventricular tachyarrhythmias. Several underlying acquired or congenital cardiac conditions are associated with an increased risk of ven-tricular arrhythmias. The implantable […]

Retinal Prosthesis System for Advanced Retinitis Pigmentosa: A Health Technology Assessment Update

 Retinitis pigmentosa is an eye disease people are born with. People who have it slowly lose their vision. The Argus II retinal implant is the only treatment approved by Health Canada for retinitis pigmentosa. A device is implanted in a patient’s eye, and it works with a special set of glasses to restore some vision to […]

Left Ventricular Assist Devices for Destination Therapy: A Health Technology Assessment

 Left ventricular assist devices help keep blood flowing through the body by assisting a specific chamber in the hearts of patients with severe heart failure. A left ventricular assist device can be implanted as a last resort for patients with severe heart failure who cannot have heart transplantation; this is called destination (permanent) therapy. Earlier devices used […]

Transcatheter Aortic Valve Implantation for Treatment of Aortic Valve Stenosis: A Health Technology Assessment

 The aortic valve is one of four valves in the heart. It allows blood to flow from the left ventricle of the heart into the aorta (the main artery in the body). Aortic valve stenosis occurs if the valve narrows and cannot open all the way, partially blocking the flow of blood out of the heart. […]

Health technology assessment on spinal implants

Spinal surgery, including fusion and dynamic stabilisation, is one of the available treatment options for patients with symptomatic degenerative changes of the lumbar or cervical spine. The various symptoms can include local pain, radicular pain due to nerve root compression, as well as other neurological symptoms such as muscular weakness and numbness.  Dynamic stabilisation has been […]

Transcatheter implantable devices for mitral valve repair for chronic mitral valve regurgitation

The aim of the present rapid assessment was to summarise the information on the relative effec-tiveness and safety of transcatheter implantable devices for mitral valve repair in adults with chronic mitral regurgitation (MR). Three different transcatheter therapeutic approaches and related devices were considered: leaflet repair with MitraClip® System (Abbott Vascular International), annulus repair with CARILLON® Mi-tral Contour […]

Assessment on Implantable Defibrillators and the Evidence for Primary Prevention of Sudden Cardiac Death

Implantable cardioverter–defibrillators (ICDs) are battery-powered implantable devices that monitor heart rhythm and deliver therapy in the form of either electric shock or antitachycardia pacing (ATP) when a life-threatening ventricular arrhythmia is detected. ICDs have been used in patients who survived sustained ventricular arrhythmias to prevent sudden cardiac death (SCD). In recent years, ICDs have also been […]

Implantable devices for closure of patent foramen ovale (PFO) in adults

Percutaneous closure of patent foreman ovale (PFO) is one of the treatment options for patients with PFO suffering from transient ischemic attacks (TIA), cryptogenic stroke or persistent migraine. At time of writing, none of the several CE marked PFO closure devices have been approved by the US Food and Drug Administration (FDA). Currently there are 12 different PFO closure devices […]
