National Registry for Supported Angioplasty: Results and Follow-Up of Three Years of Supported and Standby Supported Angioplasty in High-Risk Patients

Abstract

The National Registry of Supported Angioplasty was formed in 1988 to collect data on patients undergoing supported angioplasty. The Registry was expanded to include patients also undergoing standby supported angioplasty. In 3 years the Registry collected data on 801 patients undergoing supported or standby supported angioplasty. The data indicate that in patients with low ejection fractions and/or > 50% of jeopardized myocardium at risk can have an interventional procedure performed with a 6.9% risk of mortality with prophylactic or standby support, but patients with < 20% ejection fraction do better with prophylactic support. In addition, patients with LMCA stenosis and age > 70 years are at higher risk. The Registry also demonstrates good long-term results for patients who have undergone the procedure.

PTCA with the use of cardiac assist devices: Risk stratification, short- and long-term results

“…According to the American High-Risk PTCA Register, hospital mortality was 6.9% and the survival rate after 24 months was 80% [24]. The higher mortality found in our study can be explained by the higher NYHA status of our patients (3.7 vs. 1.9).…”

Successful high-risk coronary angioplasty in a patient with cardiogenic shock under circulatory assist with a 16F axial flow pump

“…The device was removed after a weaning time of 8 hr, using local compression. The National Registry for supported angioplasty reported 15% peripheral vascular complications after percutaneous circulatory support with 18F [13]. After use of an IABP, 5.9% patients developed major vascular complications [14].…”

Current status of percutaneously inserted cardiopulmonary bypass in the cardiac catheterization laboratory

“…The earliest reports of supported angioplasty were provided by the National Registry for Supported Angioplasty [3,4], which included nearly 1,000 patients and demonstrated that high-risk patients could have coronary intervention safely performed, but at a high frequency of vascular complications.…”
