Plaque debulking before stenting is still controversial. We performed a meta-analysis of 12 randomized and non-randomized trials comparing directional coronary atherectomy (DCA) before stenting versus stenting alone. Angiographic end points were acute gain, late loss and angiographic restenosis rate. Clinical end points were early major adverse cardiac events [MACEs: death, Q-wave myocardial in...
OBJECTIVES We sought to compare outcomes between patients with acute myocardial infarction (AMI) undergoing percutaneous transluminal coronary angioplasty (PTCA) with an optimal or "stent-like" result versus patients who underwent routine stent placement. BACKGROUND Recent studies in patients with AMI undergoing stent implantation have suggested that PTCA may no longer be a relevant treatment...
BACKGROUND Ostial left anterior descending coronary artery (LAD) lesion has been regarded as a lesion subset unsuitable for coronary stenting. Long-term outcomes of sirolimus-eluting stent (SES) implantation for ostial LAD lesions have not been adequately evaluated. METHODS AND RESULTS Among 12 824 patients enrolled in the j-Cypher Registry, 3-year outcomes were compared between 481 patients ...
BACKGROUND Preservation of renal function is an important objective of renal artery stent procedures. Although atheroembolization can cause renal dysfunction during renal stent procedures, whether adjunctive use of embolic protection devices or glycoprotein IIb/IIIa inhibitors improves renal function is unknown. METHODS AND RESULTS One hundred patients undergoing renal artery stenting at 7 ce...
BACKGROUND AND AIM Ureteroscopic lithotripsy (URL) and extracorporeal shock wave lithotripsy (ESWL) are two widely used methods for the treatment of ureteral stones. The need for ureteral stenting during these procedures is controversial. In this meta-analysis, we evaluated the benefits and disadvantages of ureteral stents for the treatment of ureteral stones. METHODS Databases including PubM...
OBJECTIVES The aim of this study was to evaluate the immediate and long-term outcome of intracoronary stent implantation for the treatment of coronary artery bifurcation lesions. BACKGROUND Balloon angioplasty of true coronary bifurcation lesions is associated with a lower success and higher complication rate than most other lesion types. METHODS We treated 131 patients with bifurcation les...
Percutaneous transluminal angioplasty with stenting (PTA/stenting) for intracranial atherosclerotic stenoses is usually performed without any protection devices. We report a unique case of atherothrombotic stenosis with the vulnerable plaque in the cavernous portion of the internal carotid artery (ICA), which was successfully treated by PTA/stenting under cerebral protection with the flow rever...
"Optimal" percutaneous transluminal coronary angioplasty (PTCA) may have a late restenosis rate similar to stenting. We sought to assess short- and long-term results of a provisional stenting/optimal PTCA approach compared with elective stenting in a prospective, randomized study. A total of 97 patients with discrete, de novo lesions in native coronary arteries > or =3 mm in diameter were rando...
BACKGROUND Direct stenting without balloon dilatation may reduce procedural costs and duration, and hypothetically, the restenosis rate. This study was designed to compare the in-hospital and long-term outcomes of direct stenting (DS) versus stenting after pre-dilatation (PS) in our routine clinical practice. METHODS The 1 603 patients treated with stenting for single coronary lesions were en...
BACKGROUND Predictors and long-term prognosis of late stent malapposition (LSM) after bare-metal stent (BMS) implantation are unknown. METHODS AND RESULTS We evaluated the incidence, mechanisms, predictors, and long-term prognosis of LSM after BMS implantation in 881 patients (992 native lesions) in whom intravascular ultrasound was performed at index and 6-month follow-up. LSM was defined as...
