Despite the apparent superiority of arterial conduits for coronary artery bypass grafting (CABG), the long saphenous vein remains the most commonly used graft. The high failure rate of long saphenous vein grafts (SVGs) over time is therefore an important limiting factor for the long-term outcomes of CABG. Various methods to improve SVG patency have been proposed, although few have had a significant impact on clinical practice. External SVG supports have been a focus of research over the past 50 years, with their use intended to minimize well-documented pathophysiological changes that occur in the SVG following implantation into the coronary circulation...

Objectives: To compare susceptibility of five different stent platforms with longitudinal stent deformation (LSD) using a clinically relevant bench testing model simulating both short and long malapposed lengths. Background: Recent data suggest that design modifications to the Promus Element stent which led to the Promus Premier stent has reduced susceptibility to LSD. However, susceptibility to LSD at long malapposed lengths has not been tested. Furthermore, the mechanisms behind susceptibility to LSD are as yet unclear...

Coronary artery perforation (CAP) is a rare, but potentially mortal possible complication of percutaneous coronary intervention. There are several treatment options for this complication, including prolonged balloon dilatation, use of a coronary stent graft, and bypass surgery. In this case report, a 65-year-old female patient who was admitted to the catheter laboratory with a diagnosis of acute coronary syndrome, was presented. Coronary angiography revealed total occlusion in the mid segment of the right coronary artery and a drug-eluting stent was implanted under 12 atm of pressure following pre-dilatation with a perfusion balloon...

BACKGROUND: Cancer patients with recently placed drug-eluting stents (DESs) often require premature dual antiplatelet therapy (DAPT) discontinuation for cancer-related procedures. Optical coherence tomography (OCT) can identify risk factors for stent thrombosis such as stent malapposition, incomplete strut coverage and in-stent restenosis and may help guide discontinuation of DAPT. METHODS: We conducted a single-center prospective study in cancer patients with recently placed (1-12 months) DES who required premature DAPT discontinuation...

Heavily calcified lesions are encountered with increasing frequency during percutaneous coronary interventions (PCI). This poses a significant problem as it often leads to suboptimal stent expansion, which in turn is a major cause for stent restenosis and thrombosis. Various technologies have been developed to tackle this. The high-pressure balloon (OPN) seems to be a promising adjunct in treating undilatable lesions. In this concise mini review we highlight the use of HPB and we present the current status of technology implemented in complex PCI cases...

Significant progress has been made in the percutaneous coronary intervention technique from the days of balloon angioplasty to modern-day metallic drug-eluting stents (DES). Although metallic stents solve a temporary problem of acute recoil following balloon angioplasty, they leave behind a permanent problem implicated in very late events (in addition to neoatherosclerosis). BRS were developed as a potential solution to this permanent problem, but the promise of these devices has been tempered by clinical trials showing increased risk of safety outcomes, both early and late...
