BACKGROUND Patients with a patent foramen ovale (PFO) and paradoxical embolism are at risk for recurrent thromboembolic events. This study investigated the long-term risk of recurrent thromboembolic events in patients with PFO and paradoxical embolism after percutaneous PFO closure. METHODS AND RESULTS Since 1994, a total of 80 patients with PFO and at(More)
INTRODUCTION For the prevention of contrast-induced nephropathy (CIN) after coronary angiography, hydration by 0.9% sodium chloride solution and N-acetylcysteine is currently recommended. However, it is unclear whether volume supplementation with sodium bicarbonate is better than with sodium chloride when used in conjunction with nonionic, low-osmolar(More)
The purpose of this study was to compare the diagnostic value of MR angiography (MRA) with conventional contrast angiography in coronary artery disease. Thirty-five patients underwent MRA and coronary angiography within 4 hours. Of these, three patients were investigated twice: once before and once after balloon angioplasty. The pulse sequence was a(More)
PURPOSE To examine the clinical consequences and/or potential need for postinterventional transposition after stent-graft occlusion of the left subclavian artery (LSA). METHODS The records of 171 consecutive patients (128 men; mean age 60.2+/-13.2 years, range 20-83) undergoing elective stent-graft repair in the thoracic aorta were reviewed to identify(More)
PURPOSE To report a case-controlled safety and feasibility study of transcatheter transplantation of autologous skeletal myoblasts as a stand-alone procedure in patients with ischemic heart failure. METHODS Six men (mean age 66.2+/-7.2 years) were eligible for transcatheter transplantation of autologous skeletal myoblasts cultured from quadriceps muscle(More)
Autologous bone marrow cell transplantation (BMCs-Tx) is a promising novel option for treatment of cardiovascular disease. We analysed in a randomized controlled study the influence of the intracoronary autologous freshly isolated BMCs-Tx on the mobilization of bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with acute myocardial(More)
Due to its role in the balance between coagulation and fibrinolysis, thrombin activatable fibrinolysis inhibitor (TAFI) may be involved in the development of cardiovascular diseases. We studied 362 patients with coronary artery disease (CAD) and 134 control subjects free of CAD, both groups investigated by angiography. TAFI antigen levels were determined in(More)
Femoral artery pseudoaneurysm is a significant problem in patients undergoing arterial diagnostic or therapeutic catheterization. The aim of this investigation was to report the incidence of pseudoaneurysm after arterial catheterization and the success rate of ultra-sound-guided compression repair. During a 3-year period (11/91-11/94) 9,051 patients(More)
OBJECTIVES To determine the success rate of transcatheter closure of secundum atrial septal defects (ASDs) in adults and to characterize anatomical structures predisposing to unsatisfactory results. PATIENTS AND METHODS Preinterventional and follow-up transesophageal echocardiography of 17 consecutive patients treated with a Sideris buttoned device was(More)
A randomized study was conducted to assess the feasibility of 4 Fr catheters for diagnostic coronary angiograms. A total of 1,114 consecutive patients were randomized to 4 or 5 Fr catheters. Ease of use of catheters was subjectively assessed by the primary operator and the picture quality was assessed by two independent observers with a good interobserver(More)
