percutaneous intervention

BACKGROUND: Herniated intervertebral disc disease (HIVD) is a common cause of lower back and leg pain. Percutaneous endoscopic lumbar discectomy (PELD) is indicated when non-surgical treatments such as medication and interventions are intractable. Ruptured discs and loose fragments inside discs are removed during PELD. Nerve root decompression is usually assessed by visualizing the free movement of the traversing nerve root or epidural fat, the free passage of a probe into the epidural space, the depression of the annulus, and the removal of the expected ruptured discs and loose fragments based on preoperative magnetic resonance images (MRI)...

AIM: The aim of this report is to provide hospitals in New Zealand with data about their own outcomes for percutaneous coronary intervention (PCI) procedures and allow comparisons with other New Zealand units and with international data. METHODS: All PCI procedures (n=5,033) were identified in nine public hospital catheterisation laboratories between 1 October 2014 and 30 September 2015. Risk-adjusted mortality rates were derived for each hospital and compared with the national rate...

The interdependence of the predictive accuracy of serum osteoprotegerin (OPG) and von Willebrand factor (vWF) levels for long-term cardiovascular outcomes has not been investigated so far. This was a prospective observational cohort study in 361 patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). Baseline levels of OPG, vWF, active vWF (act vWF) and ristocetin cofactor activity (vWF:RICO) were measured. Cardiovascular mortality was recorded over a median of five years...

A 47-year-old female presented to emergency clinic due to non-ST-elevation myocardial infarction (NSTEMI). After receiving acetylsalicylic acid, a loading dose of ticagrelor 180 mg and intravenous unfractionated heparin, she underwent successful placement of drug eluting stent on the distal part of non-dominant left circumflex artery. The patient had no pre-existing atrioventricular (AV) block and did not use AV blocking agent. Approximately 10 h after taking a loading dose of ticagrelor, baseline normal rhythm degenerated to the first and then complete AV block, with mild dizziness...

BACKGROUND: We aimed to compare the clinical outcomes of clopidogrel, prasugrel, and ticagrelor in clinical practice using the National Cardiovascular Database ACTION Registry(®). Treatment guidelines for patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention recommend dual antiplatelet therapy (DAPT) for 12 months. Few clinical trials have compared the safety and efficacy of clopidogrel with that of newer antiplatelet therapies. METHODS: A retrospective study of patients hospitalized for ACS at Cleveland Clinic Akron General was conducted...

BACKGROUND: Bradycardia on presentation is frequently observed in patients with right coronary artery ST-segment elevation myocardial infarction, but it is largely unknown whether it predicts poor angiographic or clinical outcomes in that patient population. We sought to determine the prognostic implications of admission heart rate (AHR) in patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion. METHODS AND RESULTS: We analyzed 1460 patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion enrolled in the randomized HORIZONS-AMI (Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction) trial who underwent primary percutaneous coronary intervention...

BACKGROUND: The Evaluating Xience and left ventricular function in PCI on occlusiOns afteR STEMI (EXPLORE) trial did not show a significant benefit of percutaneous coronary intervention (PCI) of the concurrent chronic total occlusion (CTO) in ST-segment elevation myocardial infarction (STEMI) patients on global left ventricular (LV) systolic function. However a possible treatment effect will be most pronounced in the CTO territory. Therefore, we aimed to study the effect of CTO PCI compared to no-CTO PCI on the recovery of regional LV function, particularly in the CTO territory...

BACKGROUND: The efficacy and safety of polymer-free stent (PFS) versus permanent polymer drug-eluting stent (PPDES) in patients undergoing percutaneous coronary intervention (PCI) remain controversial. Our meta-analysis was undertaken to evaluate and compare the efficacy and safety of PFS with those of PPDES in patients undergoing PCI. METHODS: We searched PubMed, Cochrane Library, EMBASE, and Clinical Trials.gov databases for randomized controlled trials (RCTs)...

Importance: Current comparative outcomes among black and white patients treated with percutaneous coronary intervention (PCI) in the Veterans Affairs (VA) health system are not known. Objective: To compare outcomes between black and white patients undergoing PCI in the VA health system. Design, Setting, and Participants: This study compared black and white patients who underwent PCI between October 1, 2007, and September 30, 2013, at 63 VA hospitals using data recorded in the VA Clinical Assessment, Reporting, and Tracking System for Cardiac Catheterization Laboratories (CART-CL) program...

BACKGROUND: Percutaneous coronary intervention (PCI) is currently the most common intervention for cardiovascular disease. Standard care after PCI typically involves a period of bed rest in the supine position, but this position creates voiding difficulties. OBJECTIVE: This study aimed to determine whether a modified supine position could facilitate bladder emptying after PCI. METHOD: A randomized controlled trial involving 300 patients was conducted...

BACKGROUND: Symptomatic or significant vascular lesions of Takayasu arteritis (TA) need interventions. Although percutaneous transluminal angioplasty with balloon is a less invasive and safe method, stent implantation in TA can be an alternative option. However, superiority between balloon angioplasty and stenting in TA is not conclusive. METHODS: A meta-analysis comparing balloon angioplasty and stenting outcomes was performed using the MEDLINE and EMBASE databases...

BACKGROUND: The efficacy and safety of bivalirudin (Biva) versus heparin in patients with diabetes mellitus (DM) who undergo percutaneous coronary intervention (PCI) remain controversial. Our meta-analysis was undertaken to evaluate the efficacy and safety of Biva compared with those of heparin in patients with diabetes undergoing PCI. METHODS: We searched PubMed, EMBASE, Cochrane Library, and Clinical Trials.gov databases for randomized controlled trials (RCTs)...

INTRODUCTION: Patients with ileal conduit urinary diversions are at an increased risk of long-term upper urinary tract (UUT) complications, including anastomotic strictures, infections, and urolithiasis. The reconstructed urinary system poses challenges for endoscopic manipulation. We present and describe our dual-center experience in performing retrograde ureteroscopy to treat or diagnose UUT abnormalities in patients with ileal conduit incontinent diversion. PATIENT AND METHODS: We performed a retrospective analysis of medical records for all patients with previous urinary diversion who underwent retrograde ureteroscopic procedures via the ileal loop in our institutions over a 9 year period (between June 2007 and August 2016)...

OBJECTIVES: We sought to determine the prevalence, predictors, and clinical impact of target lesion calcification in patients undergoing percutaneous coronary intervention (PCI) with newer generation drug-eluting stents (DES) and devices. BACKGROUND: Coronary calcification is independently associated with adverse outcomes following PCI. While newer DES and contemporary devices are considered safer and more efficacious, their influence on outcomes following PCI of heavily calcified lesions is unknown...

Performance of percutaneous coronary intervention (PCI) is associated with several occupational hazards including radiation exposure and musculoskeletal injury. Current methods to mitigate these risks range from suspended radiation suits to adjustable lead-lined glass shields. Robotic-assisted PCI is a novel approach to PCI that utilizes remote-controlled technology to manipulate catheters thereby significantly reducing radiation exposure to the operator and catheterization laboratory staff. Although limited, current evidence indicates that robotic-assisted PCI is associated with a high technical success rate and may have additional advantages over conventional PCI, such as a decreased incidence of geographical miss...

OBJECTIVES: To compare mid-term outcomes between patients undergoing proximal left anterior descending artery (LAD) percutaneous coronary intervention (PCI) with second generation drug-eluting stent (DES) or bare-metal stent (BMS). BACKGROUND: PCI with BMS and first-generation DES have shown to be safe options for the treatment of proximal LAD stenosis, however associated with considerable reintervention rates. Overall, second-generation DES has proven to be superior to BMS and first-generation DES, nevertheless, its effect for proximal LAD PCI has not previously been reported...

We report a case of percutaneous coronary intervention with drug coated balloon (DCB) for the in-stent restenosis of polytetrafluoroethylene-covered stent. One year follow-up angiography was excellent and in-stent lumen enlargement compared with the postprocedure and 6-months follow-up was demonstrated by optical coherent tomography. This case suggested the utility of DCB as a therapeutic option for covered-stent restenosis.

OBJECTIVES: We evaluated the angiographic and clinical outcomes in patients with severely calcified lesions and systolic dysfunction who underwent orbital atherectomy (OA). We hypothesized that OA would provide similar outcomes in patients with systolic dysfunction compared with patients with preserved systolic function. BACKGROUND: Systolic dysfunction is associated with an increased risk of adverse clinical events after percutaneous coronary intervention (PCI)...

BACKGROUND AND OBJECTIVES: Percutaneous transhepatic biliary drain is an intervention used to relieve malignant biliary obstruction. This study aims to explore survival after biliary drain insertion, predictive factors of survival and effectiveness to reduce total bilirubin level. METHODS: We conducted a retrospective analysis of 72 patients who had malignant biliary obstruction and received biliary drain during the time period between March 2005 and February 2015...

We report a case a 70-year-old female presenting with abdominal pain who has a cystic duct coursing medial to the common bile duct before anastomosing just proximal to the ampulla. Low medial insertion of the cystic duct is a rare anatomic variant that is easily misidentified on imaging studies and may complicate surgical and percutaneous intervention. It can be identified by pre-operative imaging modalities such as magnetic resonance cholangiopancreatography.
