✦ Synopsis
High-risk patients not eligible for coronary artery bypass grafting (CABG) are being considered for percutaneous coronary interventions, using cardiopulmonary support (CPS) or intraaortic balloon pump (IABP). However, few data are available regarding case selection and outcome with various support devices. Over a 4-yr period, 149 patients underwent high-risk coronary angioplasty, using elective placement of support devices. Based on physician preference, 58 patients underwent CPS and 91 underwent IABP support prior to the angioplasty. Patients selected for CPS-assisted angioplasty were more likely to be males, and to have a history of chronic angina, congestive heart failure, and lower ejection fraction (26+/-13% vs. 32+/-14%, P = 0.01). Multivessel disease was present in 95% of CPS patients and 89% of IABP patients (P = 0.35). Multivessel angioplasty was performed more frequently in the CPS group (40% vs. 20%, P = 0.01), and angioplasty success was higher in the CPS groups (99% vs. 87%, P = 0.005). Major cardiac events such as myocardial infarction, bypass surgery, stroke, and death did not differ between the groups. Peripheral vascular complications such as hematomas (36% vs. 24%, P = 0.16), vascular repair (14% vs. 3%, P = 0.03), and transfusions (60% vs. 27%, P = 0.0001) were higher in the CPS group. In conclusion, despite a higher risk profile, CPS allowed longer balloon inflations and higher PTCA success rates compared to IABP. However, peripheral vascular complications were higher in the CPS group, and major cardiac events were similar to those in IABP-treated patients. These data suggest that either method of support may be acceptable during high-risk PTCA.
