Between January 1980 and July 1983, percutaneous transluminal angioplasty was attempted on 137 stenotic renal arteries in 100 patients. At termination of follow-up studies (3-39 months, mean of 16 months), 70% of those treated for hypertension had benefited from the procedure. Stenosis secondary to fibromuscular dysplasia responded better than stenosis from arteriosclerosis (85% and 65% of the patients, respectively). Benefit was minimal for those with stenosis of the renal artery ostium or renal insufficiency. Determining levels of renal vein renin before angioplasty is helpful in selecting patients; following angioplasty, this has considerable significance in predicting the success of the procedure.

Guidewire entrapment (GE) is a rare complication that warrants complex interventions or surgical procedures. Here, we report the removal of an entrapped guidewire using excimer laser coronary angioplasty (ELCA) in a case of chronic total occlusion (CTO). Plaque tissue trapped with the guidewire was also removed.

Objectives: The Wolverine cutting balloon (CB) (Boston Scientific) is a specialized balloon catheter with microsurgical blades that is used for balloon-resistant lesions. The Manufacturer and User Facility Device Experience (MAUDE) database serves as a repository for reports of medical device complications. The aim of this study was to analyze complications associated with CB use during percutaneous coronary intervention in real-world contemporary practice.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.

Background: Takotsubo syndrome (TTS) is characterized by transient left ventricular dysfunction, often triggered by emotional or physical stress. It usually presents with clinical features similar to acute coronary syndrome, making its occurrence following elective percutaneous coronary intervention (PCI) challenging to diagnose and treat.
Case Summary: A 67-year-old man with ischaemic heart disease and recurrent angina underwent elective PCI of the right coronary artery.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.
