In the late 1970s, doctors began using balloon angioplasty to treat coronary arteries that got too narrow. (9) • Balloon dilation of airway stenosis has been performed in both children and adults. In the 40 years since Gruntzig’s first angioplasty,1 percutaneous coronary intervention (PCI) has become one of the most frequently performed therapeutic interventions in medicine.2 Devices and techniques have evolved during this period and facilitated improved patient outcomes, so unlike Gruntzig it is no longer necessary to have a cardiac surgeon present for every procedure. Cutting balloon: a novel approach to percutaneous angioplasty. Among patients in whom surgery for supravalvar aortic stenosis is contemplated, stenosis of the branch pulmonary arteries is common. Endovascular salvage plays an important role in dialysis access care. Despite various forms of pharmacologic treatment and surgical interventions most patients with PA stenosis succumb to right heart failure secondary to severe pulmonary hypertension (1). The devices see wide application for de novo lesions, in-stent restenosis, and adjunctive therapy for drug-coated balloons.
