Filter by:The aim of this prospective, monocentric, non-randomized trial is to investigate the impact of catheter ablation of atrial tachyarrhythmias on the ABC-stroke and ABC-bleeding risk scores. Participants planned for first catheter ablation for symptomatic atrial tachyarrrhythmias (atrial fibrillation, atrial flutter) will be enrolled. Serial blood samples will be collected before and 3, 6 and 12 months after catheter ablation to calculate the ABC scores as well as the traditional bleeding and stroke risks. Following catheter ablation, continuous rhythm monitoring will be achieved using an insertable monitor or an implanted atrial lead of a cardiac implantable electronic device. Additionally, heart rate monitoring via photoplethysmography using a smartwatch and/or smartphone is performed for a period of six months. Data are analyzed for differences in ABC scores before and after ablation in relation to possible AF/AT recurrences. Furthermore, we are going to compare the sensitivity and specificity of different follow-up modalities post ablation. The monitoring via ICM (gold standard) is compared to smartwatch-based monitoring alone, versus smartphone-based monitoring alone or a combination of both for AT/AF recurrences.
The recurrence of endometriosis after surgery a formidable challenge for the gynecologist. Recurrence rates reported in the literature are very high, being 21.5% at 2 years and 40-50% at 5 years. Several theories attempt to explain these high figures. The three most widely accepted are: - The presence of residual endometriotic tissue or residual endometriotic cells not completely eradicated during surgery - The growth of undetected microscopic endometriosis during surgery - The development of endometriotic lesions de novo Patients with symptomatic endometriosis diagnosed by ultrasound or MRI and suitable for surgery will participate in the study. The surgical specimens sent for pathology from bladder, vagina, uterosacral, sigma or rectum will be properly marked for studying the presence of endometriosis.
Chronic pain may be a long-term problem after inguinal Lichtenstein hernioplasty. The aim of this study was to compare long-term results of hernioplasty using three different meshes (partly absorbable, lightweight polypropylene and thick polypropylene mesh).
