چکیده
Percutaneous cardiac interventions were introduced in the 1960s, and, with the introduction of percutaneous coronary interventions by Gruentzig in 1978, the field has had an astounding growth. Percutaneous coronary intervention (PCI) is the most commonly preformed revascularization technique in the United States today with an estimated 492 000 procedures done in 2010 (Figure 1). This exceeds the number of coronary bypass operations estimated to be 397 000. Likewise, the growth of structural heart disease, in particular, valvular heart disease, has been remarkable with >10 000 procedures in 2013 in the United States 2 years after approval and 38 000 over the first 5 years of approval in Europe. It is estimated that > 200 000 transcatheter aortic valve replacement (TAVR) procedures have been done worldwide to date. Growth in TAVR has increased the volume of surgical aortic valve replacement as well (Figure 2). Invasive pediatric interventions have accelerated over the past decade with better devices and improved success. Peripheral vascular interventions have also grown, expanding into venous in addition to arterial interventions. The field of interventional cardiology is now much broader and more complex than ever before and specialization within interventional cardiology is increasing. This review will discuss 2 areas where change has been most dramatic: coronary and valvular interventions.

Concerns about ionizing radiation during interventional cardiology have been increased in recent years as a result of rapid growth in interventional procedure volumes and the high radiation doses associated with some procedures. Noncancer radiation risks to cardiologists and medical staff in terms of radiation-induced cataracts and skin injuries for patients appear clear potential consequences ...
متن کاملSome implications for clinical cardiology of recent advances in interventional cardiology.
RECENT YEARS have seen the development of many new techniques and therapies that are useful or potentially useful in the management of patients with cardiovascular diseases. A number of these procedures performed by cardiologists have given rise to the term "interventional cardiology," referring to the more active, interventional role of the physician performing the procedure as compared with t...
