Comparative Study
[Revascularization in patients with prior coronary bypass surgery].
Increasingly over the past several years, patients have returned after coronary surgery for reintervention procedures. This reflects immediate postsurgical complications and the relentless progression of coronary artery disease in the native circulation and in the bypass grafts. Although there are randomized comparative data for coronary bypass surgery (CABG) versus percutaneous transluminal coronary angioplasty (PTCA) and medical therapy, these trials have always excluded patients with previous (GABG). ⋯ In this non-randomized study of patients with previous CABG requiring revascularization procedures, PTCA resulted in lower procedural morbidity and mortality risks. At follow up, both PTCA or CABG were similar for event-free survival; PTCA offered lower overall mortality, although it is associated to a greater need for subsequent revascularization procedures.
