Unknowns by 2011

• Unknown durability in humans after 6 years

• Unknown effects on heart failure progression

• Unknown effects of remaining AoI on ventricular remodeling

• Unknown effect on the ability to do subsequent valve repair or replacement

MCRI's On-X Prosthetic Heart Valve in Aspirin Study; Clinical Study May Provide Evidence to Support Eliminating the Use of Warfarin As an Anticoagulant for On-X Mechanical Valve Recipients

PROACT: Early results show high-risk patients do well with low warfarin and carbon valve

Indirect MITRAL VALVE AnnuloplastyCS – Reshaping

NIH CERCLAGE of Lederman

• Circumferential tension around mitral annulus• CS – proximal septal branch of GCV –

image guided (MRI roadmapping coupled with fluoroscopy) traversal of myocardium to reenter right heart chambers

• Circle is closed by snare retrieval than applying and fixing graded tension to reduce MR

• Successful MR reduction in 14/16 swine with suitable anatomy

Direct Annuloplasty

• Retrograde access to post MV annulus - Direct annular reduction: Suture-anchor plication

• Guiding catheter in CS with radio-opaque markers placed at P1, P2 and P3

• Trident catheter delivers wires in P1, P2 and P3• FIM: Jan-2008 – Dr. Adrian Ebner – Paraguay• CE Pilot study PI: Prof. E. Grube

Figure 1. Transesophageal echocardiographic views of the mitral valved stent. Figure 1A shows the valved stent along LV long axis view at 0 degree angle. Note the visible valve leaflets inside the body of the stent. Figure 1B represents the color frame showing the unobstructed LVOT and its relationship with the new mitral valved stent.

Figure 2. TEE Doppler examination of the mitral valved stent and LVOT flows. Figure 2A illustrates the amount of regurgitation (trace) on Continuous Wave Doppler exam to assess the forward flow through the mitral valved stent. Figure 2B shows the Pulse Doppler exam through the LVOT showing unobstructed flow by the neighboring mitral valved stent.
