Mitral Regurgitation (MR)

MR in Australia2-5

~500-600K

Australians were living with heart valve disease in 2021

Estimated to be >400k Australians with MR

MR is the most common specific type of heart valve disease

Age-Related

~1-2% in <60 years and ~9-11% in those > 70 years

Expected Increase to ~670K in 2051

With ~30% having moderate to severe disease



 

For many patients with MR, surgery is contraindicated and medications are insufficient  

49% of patients with symptomatic severe MR were not operated due to age, co-morbidities, or impaired LV.6*
MR patients who most need intervention are often the most likely to be denied surgery.6

*Based on a survey of severely symptomatic MR patients in NYHA Class III-IV (n = 396); 10% had surgery the following year. The remainder had no surgery; medical management only.


 

A Leaky Heart Valve Reduces Quality of Life7-9

In some cases, people with a leaky valve (mitral regurgitation) may never experience symptoms of heart failure, and the condition can worsen when the heart is unable to pump enough blood to meet the body’s demands.


 

The most common symptoms of MR include:

Shortness of breath

Fatigue

Dry, hacking cough

Excessive urination

Fainting

Swollen feet or ankles

Inability to exercise

Decrease in appetite

If left untreated, up to 57% of people with a leaky valve may not survive 1 year.10-12


 

Is there an Option for Those with Significant MR?

MitraClip™ TEER Therapy is an option for patients with significant MR who are not candidates for surgery.7

Why Choose MitraClip™ TEER Therapy?2-7

MitraClip™ TEER Therapy is an option for patients with significant mitral regurgitation (MR) who are not candidates for surgery. It is the only mitral valve device shown to improve survival of heart failure patients with secondary MR.

Minimally Invasive

Less invasive than traditional open-heart surgery. The device is implanted via a catheter that is inserted through an incision in the upper leg.

Improved Quality of Life

Most patients experience improvements in symptoms and quality of life after the procedure.

Short Hospital Stay

Patients are usually released from the hospital within 2 to 3 days, significantly less time compared to surgery.

Clinical Practice

The Referral Process2-5

Imaging

Imaging is used for screening patients to determine an MR diagnosis and whether a clip is needed and suitable. It is also used to facilitate the procedure of clip insertion.

Imaging for MitraClip™ TEER Implant Follows a Systematic Protocol:

Pre-procedural screening transthoracic echocardiogram (TTE) which includes mitral valve anatomical evaluation, quantification and aetiology of MR, overall patient eligibility and safety for the MitraClip™ TEER Implant.

Apical four chamber view showing mitral regurgitation

Parasternal short-axis view showing mitral valve area via planimetry

Parasternal long-axis view showing vena contracta

3D en face view of mitral valve

Pre-procedural screening transesophageal echocardiogram (TOE) which includes mitral valve anatomical evaluation, quantification and aetiology of MR, overall patient eligibility and safety for the MitraClip™ TEER Implant.

Mid-oesophageal, 5-chamber view showing mitral regurgitation with A1/P1 scallops of the mitral valve visualised

Bi-commissural midline view showing mitral regurgitation with P1/A2/P3 scallops of the mitral valve visualised

xPlane imaging showing the simultaneous (1) bicommissural and (2) long axis views of  the A2/P2 scallops of the mitral valve

xPlane imaging showing the simultaneous (1) bicommissural and (2) long axis views of  the A2/P2 scallops of the mitral valve (with Colour Doppler)

Mitral valve area measured from  3D MPRs (multiplanar reconstruction)

3D enface view of a P2 prolapse

Procedural (Transesophageal echo-TOE) helps guide the transseptal puncture, clip trajectory, clip positioning, leaflet capture, leaflet insertion assessment, clip stability, MR severity and mean pressure gradient.

Transseptal Bicaval view showing inferior – superior tenting location

Clip positioning  3D en face view showing clip arms perpendicular to line of coaptation in the Left Atrium

Transseptal Short axis view at base showing anterior-posterior tenting location

Clip positioning Long-axis view showing gripper identification

Positioning and trajectory- Bicommissural 2 chamber view with colour

Leaflet insertion assessment 3D en face view showing tissue bridge

Clip positioning Bicommissural xPlane view showing MitraClip position

Post-procedural (Transthoracic or Transesophageal echo-TTE or TOE) imaging used to evaluate MitraClipTM TEER through assessment of clip position, clip stability, MR severity and mean pressure gradient.

MitraClip™ TEER Therapy Procedure

  • Procedure is performed using femoral venous access and real-time imaging (echocardiography and fluoroscopy), thereby avoiding cardiopulmonary bypass.
  • Transcatheter beating heart procedure allows for real-time positioning and repositioning to optimise MR reduction.
  • Can be used in a standard cath lab or hybrid room.
  • Implants are safe under labelled magnetic resonance imaging (MRI) scanning conditions.§

§ Non-clinical testing has demonstrated that the MitraClip implants are MR conditional. A patient with this device can be safely scanned in an MR system meeting the following conditions:
Static magnetic field of 1.5-Tesla (1.5 T) or 3-Tesla (3.0 T)
Maximum spatial field gradient of 4,000 Gauss/cm (40 T/m)
Maximum MR system reported, whole body averaged specific absorption rate (SAR) of ¬2 W/kg (Normal operating mode)

Increased Procedure Efficiency6,7*
