Angiographic outcome in multivessel disease (GABI II study) using new coronary device interventions and comparison with GABI I trial results.

Percutaneous coronary interventions using stents were investigated in patients with multivessel disease. Acute and long-term results were compared with those of the German Angioplasty Bypass Surgery Investigation trial in a prospective multicenter study. The study included 134 patients in whom 277 lesions were treated.

Pulmonary vein diameter reduction after radiofrequency catheter ablation for paroxysmal atrial fibrillation evaluated by contrast-enhanced three-dimensional magnetic resonance imaging.

Background: Radiofrequency catheter ablation (RFCA) is a promising intervention to treat atrial fibrillation. However, pulmonary vein (PV) stenosis after RFCA has been reported. The aim of this study was to investigate the incidence and time course of pulmonary vein stenosis after RFCA within a period of 3 months.

[Pregnancy-related, rarely-seen spontaneous lumbar artery rupture].

Some arterial aneurysm ruptures can be seen during pregnancy. However, spontaneous rupture of the lumbar artery in pregnancy are very rare. In that manuscript we present a 22 year old female who is 8 months pregnant, seen at a peripheral hospital for suspicion of placenta decolmant.

Angiographic analysis of immediate and long-term results of PTCR vs. PTCA in complex lesions (COBRA study).

We conducted a prospective, randomized trial to compare immediate and long-term effects of percutaneous transluminal coronary angioplasty (PTCA) and high-frequency rotational atherectomy (PTCR) in patients with angiographically predefined complex coronary artery lesions (AHA type B2 and C). The relation of lesion characteristics to procedural results is reported in this angiographic analysis. Patients were randomly assigned to balloon angioplasty (n = 250 patients) or rotational atherectomy (n = 252 patients).

[Echocardiographic measurements of coronary flow reserves in the left anterior descending artery allows detection of significant stenosis].

Background And Objective: CFR has proven to be useful in the selection of patients undergoing invasive treatment of coronary artery disease and in estimating their prognosis. However, CFR could only be determined in everyday practice invasively during catheterization procedures. Recent development of high-resolution transthoracic color Doppler echocardiography (TTCD) allows transthoracic visualization of distal LAD and supra-apical intra-myocardial perforator branches, and non-invasive measurement of CFR.
