Coronary Artery Ectasia in Elective Coronary Angiography : Predictors, Outcomes and Management

Coronary artery ectasia (CAE) is the diffuse dilatation of coronary artery. It is defined as a dilatation with a diameter of 1.5 times the adjacent normal coronary artery . Its prevalence ranges from 1.2%-4.9% with male to female ratio of 3:1 . Coronary ectasia likely represents an exaggerated form of expansive vascular remodelling (i.e. excessive expansive remodelling) in response to atherosclerotic plaque growth . CAE is more common in males. Hypertension is a risk Factor. ...

Double or Single Dose Sirolimus-Eluting Stents in Diabetic Patients With de Novo Coronary Artery Lesions

The main objective of this study is to assess safety and effectiveness of double dose sirolimus-eluting Bx VELOCITY stents in diabetic patients with a de novo native coronary lesion, as compared to single dose sirolimus-eluting Bx VELOCITY™ stents.

Single Versus Double Injection Costoclavicular Block

In this trial, the objective is to compare single- and double-injection ultrasound-guided costoclavicular blocks. The rationale behind this idea is that a second local anesthetic injection, inside the costoclavicular space, may compensate for the dynamic cord dispersion seen with the single-injection technique. Thus the research hypothesis is that, compared to its single-injection counterpart, a double injection costoclavicular block will result in a shorter onset time.

Therapeutic Effect of Sildenafil in Patients With Coronary Vasospasm

This will be a prospective, phase IIIb, double-blind and randomized trial testing the effect of single dose sildenafil application in patients with coronary vasospasm compared to placebo application. The target variable to be tested is the degree of coronary vasoconstriction in response to intracoronary ACh application (in addition to clinical chest pain) which will be imaged by coronary angiography and measured using quantitative coronary angiography software. Main obj...

Double-lumen Tubes (DLT) - Health Economic Study

The aim of this study is to make a health economic evaluation comparing novice physicians use of VivaSight double-lumen tube and a conventional double-lumen tube for single-lung ventilation during thoracic surgery at a teaching hospital. The hypothesis is, that both double-lumen tubes are equally cost-effective and the the incidence of fiberoptic bronchoscope use it the same for both tubes.

PROSPECT: An Imaging Study in Patients With Unstable Atherosclerotic Lesions

PROSPECT is a multi-center prospective registry of Acute Coronary Syndromes (ACS) patients with single or double vessel coronary artery disease. Approximately 700 patients with ACS will be enrolled into the study at sites in the United States and European Union.

Diaphragmatic Dysfunction After Ultrasound-guided Supraclavicular Block With Single or Double Injection Technique

The investigators plan to determine the incidence of hemi-diaphragmatic paresis (HDP) with two commonly used techniques of supraclavicular nerve block, the single and double injection techniques. It is our hypothesis that a double injection peripheral nerve block technique will increase the risk of HDP when compared to a single injection technique.

Study of Single And Double Bundle ACL Graft Cross-sectional Dimensions Compared With Native ACL

To study the difference between single and double bundle ACL graft corss-sectional dimensions compared with native ACL using postoperative 3-D MRI.

Double and Single Intrauterine Insemination In Controlled Ovarian Stimulation (COH) Cycles With Multifollicular Development

Our hypothesis is double insemination will improve pregnancy rates in coh cycles with more than one dominant follicles (>16mm).

Clinical & Radiological Assessment of Rotator Cuff Healing After Single Row Vs. Double Row Rotator Cuff Repair

This study is to analyse whether there is a difference in clinical and radiological outcomes between single row and double row repair techniques for the treatment of shoulder's rotator cuff tears.

The ENDEAVOR IV Clinical Trial: A Trial of a Coronary Stent System in Coronary Artery Lesions

The purpose of this study is to assess the equivalence in safety and efficacy of the Endeavor Drug Eluting Coronary Stent System when compared to the Taxus Paclitaxel-Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) of 2.5-3.5 mm.

Single-stapled Double Purse-string Technique for Colorectal Anastomosis

A single-arm, single-center prospective study of a novel double purse-string technique for constructing the colorectal anastomosis in robot-assisted laparoscopic resection of the sigmoid colon for cancer.

Improvement of Subjective Well-Being by Ranolazine Among Unrevascularized Chronic Stable Coronary Artery Disease Patients

This is a prospective, double-blind, placebo-controlled, randomized, single-center (North Florida- South Georgia VA Medical Center) study. The study objective is to determine if ranolazine improves angina symptoms at 4 months compared with placebo among stable coronary artery disease patients who have demonstrable myocardial ischemia, but who do not undergo revascularization

Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics, of MEDI6012 in Subjects With Stable Coronary Artery Disease

A Phase 2a Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of Single-Ascending Doses of MEDI6012 in Subjects with Stable Coronary Artery Disease

Resynchronization Surgery Combined Unified Efficacy

The purpose of the study is to compare survivability of the patients with ischemic heart failure LVEF ≤ 35% after coronary artery bypass grafting or coronary artery bypass grafting combined with surgical ventricular restoration and single-step implantation of CRT system and isolated coronary artery bypass grafting or coronary artery bypass grafting with surgical ventricular restoration. (CABG + CRT or CABG + SVR + CRT vs CABG or CABG + SVR)

Treatment of Coronary Bifurcation Lesions: Comparing Reverse T and Protrusion Versus Double-kissing and Crush Stenting

Treatment of bifurcation coronary lesions may be challenging, and the best technique to be used in these settings remains to be established. While a single stent strategy is simpler and has been often encouraged, a number of studies show that the use of modern stent implantation techniques may bring some advantages in terms of target lesion failure during longer follow-up. Further, single-stent procedures are not possible at all in some settings, for instance when both main and...

The Success of Opening Single CTO Lesions to Improve Myocardial Viability Study (SOS-comedy)

The purpose of this study is to investigate the effect of percutaneous coronary intervention (PCI) on myocardial viability in coronary artery disease patients with single coronary total occlusion (CTO) lesions.

The aim of the study is to examine the influence of number of the harvested hamstring tendons on subjective and objective outcomes of primary anterior cruciate ligament reconstruction.

Validation of a Single Rest-Stress Imaging Protocol for Myocardial Perfusion Imaging

We propose a single-scan two-injection myocardial perfusion imaging protocol using ammonia. Subjects will undergo single-scan two-injection imaging as well as regular stress single-scan single-injection protocol and the myocardial blood flow of both techniques will be compared.

Role of Cardioflux in Predicting Coronary Artery Disease (CAD) Outcomes

The Correlation of Heart Hemodynamic Status Between 320 Multidetector Computed Tomography, Echocardiography and Cardiac Catheterization in Patients With Coronary Artery Disease

With the advances in multidetector computed tomography (MDCT) technology, CT angiography (CTA) of the coronary arteries using 64-slice or dual-source CT systems has evolved into a robust, alternative, noninvasive imaging technique to rule out coronary artery disease (CAD). Reported sensitivities and specificities of coronary CTA can compete with those of catheter angiography. Because CT is the major source of ionizing radiation in medicine, dual isotope myocardial perfus...
