Rick, you're right, valve selection is a personal decision. We each of us need to talk with our doctors and decide what we can live with. Neither choice is perfect. But hopefully you're going to feel much better with your new valve. Best wishes.
There is no need to regulate intake of greens and veggies when taking Coumadin.
I'm not on Coumadin or Warfarin. But my Doctors told me differently from this comment and my relatives' Doctors have told them differently. Also I have read differently. But don't take my word for it. Look for official prescription warnings. Here are some excerpts of warnings:
-------------------------
From drugs.com regarding Warfarin:
Botanical (Herbal) Products and Foods
Exercise caution when botanical (herbal) products are taken concomitantly with Warfarin sodium. Few adequate, well-controlled studies evaluating the potential for metabolic and/or pharmacologic interactions between botanicals and Warfarin sodium exist. Due to a lack of manufacturing standardization with botanical medicinal preparations, the amount of active ingredients may vary. This could further confound the ability to assess potential interactions and effects on anticoagulation.
Some botanicals may cause bleeding events when taken alone (e.g., garlic and Ginkgo biloba) and may have anticoagulant, antiplatelet, and/or fibrinolytic properties. These effects would be expected to be additive to the anticoagulant effects of Warfarin sodium. Conversely, some botanicals may decrease the effects of Warfarin sodium (e.g., co-enzyme Q10, St. John's wort ginseng). Some botanicals and foods can interact with Warfarin sodium through CYP450 interactions (e.g., echinacea, grapefruit juice, ginkgo, goldenseal, St. John's wort).
Monitor the patient's response with additional INR determinations when initiating or discontinuing any botanicals.

From rxlist.com regarding Coumadin:
HOW TO USE:
Read the Medication Guide provided by your pharmacist before you start taking warfarin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor or other health care professional, usually once a day. It is very important to take it exactly as directed. Do not increase the dose, take it more frequently, or stop using it unless directed by your doctor.
Dosage is based on your medical condition, laboratory tests (such as INR), and response to treatment. Your doctor or other health care provider will monitor you closely while you are taking this medication to determine the right dose for you.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
It is important to eat a balanced, consistent diet while taking warfarin. Some foods can affect how warfarin works in your body and may affect your treatment and dose. Avoid sudden large increases or decreases in your intake of foods high in vitamin K (such as broccoli, cauliflower, cabbage, brussels sprouts, kale, spinach, and other green leafy vegetables, liver, green tea, certain vitamin supplements). If you are trying to lose weight, check with your doctor before you try to go on a diet.
Cranberry products may also affect how your warfarin works. Limit the amount of cranberry juice (16 ounces/480 milliliters a day) or other cranberry products you may drink or eat.
