In the performance of increasingly complex percutaneous coronary interventions (PCIs), there remains an ever-present risk of device fracture or dislodgement. Such occurrences are fortunately infrequent,1 however, they may pose an unfamiliar and diffi…
Renal artery stenosis (RAS) can result in renovascular hypertension and nephrosclerosis, and accounts for approximately 1 to 3% of all causes of hypertension. The current treatment of choice for atherosclerotic renal artery disease in selected patien…

Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia, with approximately 300 cases reported in the literature.1,2 It is often fatal and is mostly recognized at postmortem examination in young victims of sudde…
Coronary artery perforation is an infrequent but serious complication of percutaneous coronary intervention (PCI), occurring in some 0.3–0.6%.1–4 The classification by Ellis et al1 describes perforation as type I, an extraluminal crater without extra…
