title: Percutaneous cardiopulmonary bypass support in the catheterization laboratory: technique and complications.
abstract: A safe and easily applied technique of percutaneous cardiopulmonary bypass support has been developed for use in the cardiac catheterization laboratory. The importance of this technique lies in its ability to maintain hemodynamic stability during high risk interventional procedures regardless of intrinsic cardiac function. Venous and arterial cannulas (18F) are inserted percutaneously over a stiff guide wire after sequential dilatation with 12F and 14F dilators. Bypass flow rates of up to 5 L/min can be achieved. This technique can be applied to support patients with cardiac arrest, hemodynamic collapse after abrupt closure during coronary angioplasty, and cardiogenic shock, as well as those undergoing high-risk elective coronary angioplasty. This form of support also permits transport of the patient to the operating room in a stable condition after an unsuccessful angioplasty. The complications are mostly related to cannula removal and can be minimized by the use of a proper technique. Although the ultimate role of this new technique remains to be completely defined, it appears that it will expand the patient population for whom coronary interventions can be applied.
