What are the advantages/disadvantages of the stentless tissue valve for a reop AVR? Do you use them?
Dr. Brown has used the stentless valve in certain cases. There is no clear cut advantage to using it except in rare cases, and reoperation is not one of them.

Is minimally invasive aortic valve replacement less successful than breastbone procedure?
No, it is as successful when performed on the right patient in the right situation. Jo Ann Sikora, CRNP Aortic Valve Program Coordinator Nurse Practitioner with Dr. Jamie Brown

I have an aneurysm of my ascending aorta and a bicuspid aortic valve. I am a 49 year old male who enjoys
endurance sports and I would like to be able to continue doing these post-surgery. I also have two sons and would like to minimize the mortality risk of the surgical procedure I select. Is there a minimally invasive option
for my situation? Should I consider the Ross procedure?
Although still performed in some situations, the Ross procedure has fallen out of favor here as it takes a 1 valve problem and makes a 2 valve issue out of the procedure. Dr. Brown feels that the best option in your situation, if it can be done, is a valve sparing procedure. In order to determine that he would need to see your echocardiogram and catheterization, and we would have to perform a CT scan with reconstruction of your aorta here for evaluation. In cases where the aorta and the valve are concerned, a minimally invasive approach is not the best option.
If you are interested in being evaluated for surgery here at UMMS by Dr. Brown, please contact our office 410-328-7741.

What happens if while doing a minimally invasive aortic valve replacement it is determined that the surgery can't be performed via minimally invasive techniques? Do you go to "PLAN B," open up the chest and complete the surgery?
Dr. Brown has a protocol to evaluate patients for the minimally invasive procedure, and generally knows going in to the OR if it is a feasible option. However, safety is always primary, and if it becomes necessary that the incision be extended or changed to the traditional incision, he will do that.

I am a 36 year old male and I am considering aortic valve replacement. After surgery would I be able to to have a physically active lifestyle? What is the life of a mechanical valve? Will I be able to have normal sex life?
The chances are excellent. However, if you choose a mechanical valve over other options there is the risk of needing Coumadin (blood thinner) therapy which may impact a physically active lifestyle. Normal sex life is to be expected after surgical recovery. Jo Ann Sikora, CRNP

My 70 year old mother is going to need this surgery in the near future. Looking for the best before moving forward. Do you always use synthetic material or do you use pig valves also? Why? What makes a decision on the type of incision used?
The valve choices are mechanical, pig, or cow. The choice of valve depends on the patient's request, and the surgeon's recommendation. In someone your mother's age it is pretty clear that the pig or cow valve would be the best choice.
The choice of incisions is made after reviewing the echocardiogram, catheterization, medical information, and seeing the patient. If you are interested in forwarding this information, or setting up a consultation with Dr. Brown, please contact our office 410-328-7741.

I had open heart surgery in 1994. Now I need an aortic valve replacement as it is narrowing. I am female, 75 years of age, 5'71/2" tall, borderline diabetic, exercise 4 days weekly. I would like to avoid cracking my chest again. Is this feasable?
There is the option of the aortic valve bypass which is a newer procedure which is approached from the left side and avoids the sternum, and is a good option for patients who have had prior bypass surgery. We would need to know the status of your bypass grafts (with a catheterization) to determine if you are a candidate for this procedure.
If you would like to discuss this, please contact our office 410-328-7741.

I had CABG in 1991. Does the resulting scar tissue prevent me from being a candidate for minimally invasive aortic valve replacement?
The upper hemi-sternotomy is a good surgical option for patients who have had prior surgery. If, however, you need your bypass grafts redone, you will need traditional surgery.

I am 32 years old and I had both my aortic and mitral valve replaced with a mechanical valve. I want to know if I can have a baby with this situation?
Your cardiologist will have to advise you as to the best way to handle this situation. Coumadin is dangerous to the fetus, so your cardiologist will have to determine if there is any option for you. You also must discuss this with your women's health physician.

Can aortic valve bypass be performed on someone with a failing prosthetic valve? Also, the criteria requires no blockage of coronary arteries; what about the presence of coronary stents (4)?
Aortic valve bypass can only be performed if the valve is stenotic (narrowed). Minimally invasive aortic valve replacement can be performed if the valve is stenotic or leaking. The stents do not matter for either procedure.
If you are interested in having further discussion, or you would like to schedule an appointment for aortic valve surgery here at UMMS, please contact our office 410-328-7741.

I know there are new minimally invasive and percutaneous procedures that can correct aortic stenosis and mitral valve regurgitation without the risks of open heart surgery. If someone has both conditions, are you aware of any techniques or procedures whereby both valves can be corrected at the same time or at least would allow each valve to be corrected at separate times?
The safest approach to operating on both valves is to do a standard sternotomy.

Could you give me an estimate for the duration of the bovine cow tissue aortic valve. I am active 62 yr old male, this is my first choice.
Projections for the current generation of the bovine valve is a risk of need for re-operation at about 10% at 15 years. We use this valve predominately at UMMS is patients of all ages.

My father was diagnosed with aortic
stenosis quite a few years ago. Last
April he had to have valve replacement
surgery. Almost a year later his valve
is leaking. Is this common? If not,
what could be the cause of this?
Sometimes there is a valve leak after surgery, the question is how much and how is the valve leaking. The cardiologist or surgeon reviewing the echocardiogram should be able to give you a better idea why the valve is leaking.

Can an aortic dissection lead to an aortic aneurysm? Will someone who has had an aortic dissection secondary to a valve replacement surgery be followed closely and monitored for this?
There can be aneurysmal dilitation of an aorta which has dissected. Anyone with either of these problems should be monitored closely.

I am a 33-year-old male with a congenic bicuspid aortic valve that needs to be replaced. Everyone is suggesting an artificial valve. Could you please give me your opinion
artificial or tissue? Mininally invasive or not?
Here at the University of Maryland, we use about 98% bioprosthetic (tissue) valves. If you look at the risk of being on blood thinners over years for a mechanical valve versus the possible need for re-operation with the bio valve over years, the bio-prosthetic valve clearly is the winner.
