Are percutaneous transluminal coronary angioplasty and coronary artery bypass grafting safe enough?

Abstract

Cardiologists and cardiothoracic surgeons apply invasive procedures in increasing numbers of patients. Several studies reveal a high rate of adverse outcome and mortality, which is not related to a different composition of the patient groups or their risk profiles for complications. The answer to the question whether invasive treatment is safe enough depends on what is regarded as an acceptable risk of failure and whether failure can be reasonably prevented. The prospect of an economic reward for meeting safety standards by institutions and physicians in terms of business income or reduction of the litigation pressure, is essential. Also, adequate disclosure of risks to patients may add to their sense of safety.
