Bypass is not necessarily better. Unless you treat the underlying cause, the condition that created the plaque in the first place will continue to produce more plaque in both the stents or the bypass vessels. So over time a blockage could occur in either case again. The reason to consider the angioplasty first is that it is a much less riskier procedure and very effective. Why get your chest cut open and be put on a cardiopulmonary pump (bypass surgery) when you can just have a tube inserted through the femoral artery and into the heart (angioplasty)? Talk more to your cardiologist about your options. The key thing after having either procedure is to prevent the plaque from reaccumulating. This may require dietary changes and medicines. Hope this helps.
