weakening of the heart wall

Hi everyone
Hopefully someone can help me out. My boyfriend had some stress tests a number of months ago that pointed to restricted flow through his arteries.....the heart fills up fine, but drains poorly. The specialist has since done many many tests and has determined that repairing the arteries is not a viable option because the heart wall lining is thin and not stable. He was put on a transplant list. Since then in a few short months the wall lining has deteriorated faster than anticipated. Last week he was booked into surgery to attach mesh to strengthen the wall lining. Due to the overwhelming nature of the information, my boyfriend really did hear or understand all that is going to happen to him. He was told that the survival rate is on 50% for this surgery.
My boyfriend has really tried to isolate himself and deal with this all on his own. I feel left out but I also feel that I lack the knowledge to support him. Can someone make sense of the information he has told me....has anyone else gone through this surgery.......what does it involve, etc.

Please help
Thanks
Elizabeth

Re: weakening of the heart wall

Hi Elizabeth,

The special material to strengthen the heart wall is stitched to the surrounding tissue. If the tissue is badly damaged, it may present a problem in the short term, but may be sufficient until a heart transplant.

A weak heart wall will not have strong contractions and may not sufficiently pump blood into circulation. It is true filling would not be a problem as relaxation of heart muscle is present.

Re: weakening of the heart wall

I was told the pacemaker will not help only if the heart is "POP". It means rupture. Someone has done a research and found many documentaries to that case of rupture. One of that is "mesh" and the other one is the "super glue" which is for mended the pin hole rupture at the heart wall. They said once it ruptures, is very hard to rescue. Take care.

Re: weakening of the heart wall

Please - can someone name the actual heart defect or the name of the procedure to secure the mesh to the outside wall lining of the left ventrical.....

There are several procedures depending on the location. The septal wall (wall between heart chambers) can be repaired with patches and that would be called antrioventricular septal repair.

If the weak wall ruptures, there is an accluder device that is a small umbrella like gadget that is inserted with a cath procedure and blocks the rupture.

I have read where blood flow can be shunted (bypass) around the defected area. The operation was successful and patient's blood flow goes directly from the system to the lungs bypassing the heart's right side.

Ventricular thin-wall defects may have limited options other than a shunt, and if there is a rupture it may be fatal depending on circumstances.

Re: weakening of the heart wall

Thanks so much. The wall defect for my boyfriend is the exterior wall of the heart at the left ventrical.........not a septal issue......

any idea what the procedure or actual defect is called to attach the mesh material to the outside wall of the heart

Re: weakening of the heart wall

Here is fairly recent procedure with a passive ventricular support device. The mesh stretches around the heart. Does this information help?

SUMMER 2005

Passive Ventricular Support Device Trial


UCSF Medical Center physicians are testing a new passive ventricular support device made of material with more favorable tensile qualities than older devices.

Myocardial infarction can stimulate ventricular remodeling resulting in increased dilatation, thinning of the ventricular wall and loss of myocardial strength. Increased volumes during ventricular filling further decrease myocardial strength, which in turn leads to further increases in ventricular volume. This mechanistic loop can eventually progress to heart failure."

A passive ventricular support device is a stretchy mesh sock-like sheath that fits around the heart. The device keeps the ventricles from dilating too far during filling and assists the muscles during ventricular contraction. "What it does is put the heart back on a more efficacious Frank-Starling curve," says UCSF cardiovascular surgeon Charles Hoopes, M.D., referring to the graph describing the relationship between the left ventricle's venous return pressure and its stroke volume. Ventricular contractility and aortic resistance define individual Frank-Starling curves.

One passive ventricular support is the Acorn CorCap device, which is slipped around the heart during open-heart surgery. A clinical trial demonstrated that the CorCap device improved LV function.

The new device being tested at UCSF is manufactured by Paracor. It is similar to the Acorn device, but is made of different materials and is deployed around the heart using a thoracoscopic instrument inserted through a small hole in the chest wall. "This approach has been an advantage not only in being minimally invasive, but you also have a virgin chest if you have to come back years down the road to do a transplant or other procedure," Hoopes says. "You haven't burned any bridges."
