Filter by:Microvolt T-Wave Alternans (MTWA) is a relatively new non-invasive method for identifying patients at increased risk of sudden death from ventricular arrhythmias. MTWA can be measured during a routine exercise test, during pharmacologic stress or during cardiac pacing. Its clinical performance compares favorably with that of other non-invasive risk stratifiers and invasive electophysiologic studies. The purpose of the present study is to define the reproducibility of MTWA testing.
The purpose of this first feasibility study is to evaluate the performance of Vesta™ & VestaCOR™ (Hydroxy-Apetite coated GenX) stent in de novo native coronary artery lesions. This study will provide the longest follow-up experience available. This is a randomized, double blind study conducted at three sites, two sites in India and one in The Netherlands. To be eligible, a patient will be required to have a de novo stenotic lesion of a length that could be covered by a single stent in a native coronary artery of diameter 3.0mm and 3.5mm. A total of at least 60 patients and a maximum of 70 patients will be treated with Vesta™ & VestaCOR™ stent. These patients will be randomized to either a smooth surface nanofilm coated stent (= VestaCOR™) (approx. 35 patients) or to a porous coated stent (= Vesta™) (approx. 35 patients). All patients will be followed clinically at 30 days, 4 months, 9 months, 1, 2, 3, 4 and 5 years.
- The purpose of this study is to examine the effects of tirofiban on platelet function the Ultegra RPFA in diabetic patients undergoing elective coronary angioplasty and stenting already treated with high loading dose (600mg) clopidogrel. - About 44 people will be in the study. The study duration is a single hospitalization period during which the angioplasty will be performed in addition to a 30-day post hospitalization follow-up period. - Patients taking part in the study will be assigned by chance into two groups. - Group 1: patients will be treated with the glycoprotein inhibitor, Tirofiban (25mcg/kg over 3 min bolus dose and 0.15 mcg/kg/hr for 12-24 hours), started immediately after insertion of the sheath. - Group 2: patients will be treated with equivalent placebo All patients will be loaded with 600 mg clopidogrel at least 4 hours prior to scheduled intervention. All patients will have platelet function analyses at baseline and following treatment.
This study will evaluate the 3 drug-eluting stents presently marketed for intervention in the coronary artery with respect to the complications that may occur in case it becomes necessary to retract the stent during the intervention. It has been noted that stents carrying a drug for local application may be more difficult to retract than the more smooth bare metal stents.
The purpose of this study is to evaluate the clinical and angiographic outcome of implantation of stents eluting or not eluting Sirolimus in patients with complex coronary artery lesions suitable for percutaneous coronary intervention.
Treatment for no-option heart patients with coronary artery disease. Procedure includes the injection into the heart of a protein growth factor, administered by the Biological Delivery Systems MyoStar injection and mapping catheters, to stimulate the growth of blood vessels around blocked coronary arteries.
MyoCell™ implantation by epicardial injection during CABG surgery has the potential to add a new dimension to the management of post-infarct deterioration of cardiac function. Based on existing non-clinical studies and clinical reports, implantation of autologous skeletal myoblasts appears to lead to the replacement of non-functioning myocardial scar with functioning muscle and appears to improve myocardial performance relative to case without myoblast implantation. In a few investigational patients, myoblast implantation can be, and has been, done in conjunction with CABG and appears to have the potential to provide for additive treatment during surgery. The present study is being conducted to evaluate more fully the safety of MyoCell™ implantation via epicardial injection during CABG surgery and its effect on regional myocardial function.
