Current TREATMENT

CURRENT MEDICAL RESPONSE

The only medical response to severe symptomatic Calcific Aortic Stenosis (CAS) is currently a valve replacement, either by open-heart surgery (SAVR) or by a less-invasive procedure called TAVR (Transcatheter Aortic Valve Replacement).  
Unfortunately, not all severe symptomatic CAS patients are eligible for SAVR or TAVR (16%) (1) and some refuse surgery.

OPEN HEART SURGERY (SAVR)

The standard treatment consists in replacing the aortic valve with a biological or mechanical valve during an open-heart surgery, with extracorporeal circulation and the heart stopped – the patient is clinically dead. This surgery is a serious, expensive and risky operation. There are about 500,000 open heart surgeries performed every year worldwide (1).

TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR)

Since 2007, a new technique for minimally invasive endovascular surgery called TAVR has been used with spectacular results. This procedure consists in replacing the aortic valve via a percutaneous route passing preferably through either the aorta or the femoral artery. It allows almost all patients for whom open-heart surgery is contraindicated to be treated, but it has an incidence of vascular and hemorrhagic complications and causes cerebrovascular accidents and kidney injury.

OUR SOLUTION: A NON-INVASIVE ULTRASOUND THERAPY

To treat calcific aortic stenosis, Cardiawave has developed a Non-Invasive Ultrasound Therapy (NIUT). NIUT consists in repairing the aortic valve, not replacing it. No surgery is required. Our unique approach could represent both an alternative and a complementary approach to current procedures.
