Interaction of Intraluminal Tissue and Coronary Sinus Lead Stabilized with Stent Placement

Interaction of intraluminal tissue and coronary sinus lead stabilized with stent placement.

INTRODUCTION The aim of our investigation was to examine the intraluminal interaction of the vascular tissue and the implanted coronary sinus lead stabilized with stent on two human hearts removed before transplantation. METHODS AND RESULTS The coronary sinus lumen was sectioned under operational microscope and opened carefully. The leads and stents were found separately positioned beside eac...

Simulated extraction of stent stabilized coronary sinus leads

Cardiac resynchronization therapy (CRT) is an effective nonpharmacological therapeutic method for the treatment of selected patients with chronic heart failure with a wide QRS complex and mechanical dyssynchrony of cardiac ventricles. A new technique is used to stabilize the implanted coronary sinus lead in an appropriate position with an expanded coronary stent to maintain synchronous pacing o...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Surgical epicardial left ventricular lead versus coronary sinus lead placement in biventricular pacing.

OBJECTIVE Biventricular pacing has demonstrated improvement in cardiac function in treating congestive heart failure (CHF). Two different operative strategies (coronary sinus vs. epicardial stimulation) for left ventricular (LV) pacing were compared. METHODS Since April 1999, a total of 86 patients (pts, age: 63+/-10 years) with depressed systolic LV function (mean ejection fraction 24+/-9%),...
