Argatroban for elective percutaneous coronary intervention: The ARG-E04 multi-center study

2011

The synthetic arginine-derived direct thrombin inhibitor argatroban is an attractive anticoagulant for percutaneous coronary intervention (PCI), because of its rapid onset and offset, and its hepatic elimination. Argatroban was approved for PCI in patients with heparin-induced thrombocytopenia (HIT). However, there are limited data about argatroban in non-HIT patients. The objective of this open-label, multiple-dose, controlled study was to examine the safety and efficacy of argatroban in patients undergoing elective PCI.Of 140 patients randomized to three argatroban dose groups (ARG250, ARG300, and ARG350 with 250, 300, or 350 μg/kg bolus, followed by 15, 20, or 25 μg/kg/min infusion) and …

Prognosis and Management of Acute Coronary Syndrome in Spain in 2012: The DIOCLES Study

2015

Abstract Introduction and objectives To identify the current mortality and management of patients admitted for suspected acute coronary syndrome in Spain. The last available registry (2004-2005) reported an in-hospital mortality of 5.7%. Methods The study included patients consecutively admitted between January and June 2012 at 44 hospitals selected at random. Information was collected on clinical course at admission and on events at 6 months. Results A total of 2557 patients admitted with suspected acute coronary syndrome were included: 788 (30.8%) with ST-segment elevation, 1602 (62.7%) without ST-segment elevation, and 167 (6.5%) with unclassified acute coronary syndrome. In-hospital mor…

Radiation exposure in biliary procedures performed to manage anastomotic strictures in pediatric liver transplant recipients: comparison between radi…

2013

The aim of this study was to estimate radiation exposure in pediatric liver transplants recipients who underwent biliary interventional procedures and to compare radiation exposure levels between biliary interventional procedures performed using an image intensifier-based angiographic system (IIDS) and a flat panel detector-based interventional system (FPDS). We enrolled 34 consecutive pediatric liver transplant recipients with biliary strictures between January 2008 and March 2013 with a total of 170 image-guided procedures. The dose-area product (DAP) and fluoroscopy time was recorded for each procedure. The mean age was 61 months (range 4–192), and mean weight was 17 kg (range 4–41). The…

Endoscopic papillary large balloon dilation in patients with large biliary stones and periampullary diverticula: Results of a multicentric series.

2018

Abstract Introduction Stone extraction represents the most frequent indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic papillary large balloon dilation (EPLBD) is a recent introduced approach consisting of an endoscopic papillary large balloon dilation following limited endoscopic sphyncterotomy (ES), which has been proven to be safe and effective for extraction of large common bile duct (CBD) stones. Peri-ampullary diverticula (PAD) are described in 10–20% of patients undergoing ERCP. Aim of our study is to evaluate efficacy and safety of EPLBD for the extraction of large biliary stones in patients with PAD. Methods The prospectively collected endoscopy databa…

Less invasive (common) femoral artery aneurysm repair using endografts and limited dissection

2013

Objective We report our experience with the treatment of femoral artery aneurysms (FAAs) under local anaesthesia with limited dissection, using endografts to facilitate the proximal anastomosis and some distal anastomoses. Method Between January 2006 and December 2010, six males, mean age 72 years (range, 65–80 years) with FAAs were treated at the University Hospital of Zurich. All operations were performed under local anaesthesia with analgosedation, except for one performed under spinal anaesthesia. After limited dissection and puncture of the anterior wall of the FAA, a sheath and a self-expanding endograft were introduced over a guide wire and with fluoroscopy they were guided intralumi…

Contrast-induced Nephropathy after Percutaneous Coronary Intervention in Simple Lesions: Risk Factors and Incidence are Affected by the Definition Ut…

2011

Aim To compare the incidence, and risk factors, in-hospital and at the 18-month prognosis of contrast-induced nephropathy (CIN) according to the definition utilized: as an increase in serum creatinine (Scr) ≥0.5 mg/dL (CIN 1) or as an increase in Scr ≥25% above baseline values (CIN 2). Methods and Results We prospectively evaluated CIN according to two different definitions in 150 patients who underwent percutaneous coronary intervention (PCI) in simple lesions employing a low-medium dose of contrast media. Incidence of CIN was higher using the CIN 2 definition than CIN 1 (9.3% vs. 4%; p=0.0133). Patients with CIN 1 had a higher incidence of chronic kidney disease (CKD) (66.7% vs. 13.9%; p=…

Evidence of impaired coronary flow reserve and elevated microvascular resistances in a case of recurrent left apical ballooning.

2011

A 56-year old man was admitted for precordial pain associated with dyspnea and evidence of myocardial ischemia on ECG and cardiac ultrasound. His previous history included an episode of left apical ballooning five years before. At angiography, no evidence of significant epicardial coronary artery disease was manifest. Interestingly, both coronary flow reserve and the index of microvascular resistances were abnormal, showing evidence of impaired microvascular function. This is the first report providing direct evidence of microvascular dysfunction in a patient with (recurrent) apical ballooning.

Long-term beneficial effects of PTCA on segmental early relaxation in disease of the left anterior descending coronary artery.

1988

The relationship between regional left ventricular (LV) motion and global pressure relaxation of the left ventricle remains unclear. To clarify the recent concept of segmental early relaxation in coro nary artery disease, the authors in vestigated two groups of patients. In group I, all 12 patients (mean age 47±7 years) exhibited evidence of a normal heart after an extensive in vestigation. In group II, 25 patients (55±7 years) presented an isolated stenosis of the left anterior descend ing coronary artery, and they under went a hemodynamic investigation before and after (six to nine months) a durable successful percutaneous transluminal coronary angioplasty (PTCA). After all conventional …

Anatomical and procedural features associated with aortic root rupture during balloon-expandable transcatheter aortic valve replacement

2013

Background— Aortic root rupture is a major concern with balloon-expandable transcatheter aortic valve replacement (TAVR). We sought to identify predictors of aortic root rupture during balloon-expandable TAVR by using multidetector computed tomography. Methods and Results— Thirty-one consecutive patients who experienced left ventricular outflow tract (LVOT)/annular/aortic contained/noncontained rupture during TAVR were collected from 16 centers. A caliper-matched sample of 31 consecutive patients without annular rupture, who underwent pre-TAVR multidetector computed tomography served as a control group. Multidetector computed tomography assessment included short- and long-axis diameters an…
