OBJECTIVE Ring annuloplasty prevents acute ischemic mitral regurgitation in sheep, but it also abolishes normal mitral annular and posterior leaflet dynamics. We investigated a novel surgical approach of simple septal-lateral annular cinching with sutures to treat acute ischemic mitral regurgitation. METHODS Nine adult sheep underwent implantation of multiple radiopaque markers on the left ve...

The generation of multiple vortex cones using an annular aperture array and a spatial light modulator (SLM) is studied. The direct downscale imaging of an SLM on the surface of an annular aperture enables the direct-phase modulation of the annular aperture. It is experimentally demonstrated that the direct-phase modulation of an annular aperture array can control both the topological charge and...

The effects of tuning the parameters of an annular-ring circular patch antenna with a cross-slot are analyzed and discussed. Then, based on this structure, a novel antenna with an electromagnetic bandgap cell system, which consists of a 4×4 annular-slot array in the groundplane, is designed and both numerically and experimentally evaluated. When compared to the annular-ring patch antenna on a g...

The tricuspid valve leaflets and their annular attachments were recorded by two-dimensional echocardiography from a view of the right ventricular inflow tract obtained by placing the transducer at an intermediate position between the left ventricular apex and the left lower sternal border. The transducer was rotated, and recordings were made at 30 degrees rotational intervals around the circumf...

primary leiomyosarcoma of the broad ligament is a very rare, rapidly progressive and highly malignant gynecological tumor and only 16 cases have been reported in the literature. here, presentation of leiomyosarcoma of the left broad ligament in a 26-years-old woman is reported. clinical presentation and histological diagnosis is discussed. the patient has been treated surgically and remains dis...

BACKGROUND It is unknown whether longitudinal rotation (LR), often seen in cardiac resynchronization therapy candidates, may affect mitral annular early diastolic (E') velocities and tricuspid annular motion. We assessed whether (1) LR affects the amplitude and timing of septal and lateral mitral annular E' velocities and tricuspid annular systolic and E' velocities and (2) if systolic strain h...

In the recent years sport climbing has become more and popular. As an extreme sport, it is prone to a high degree of injury risk. A particular body part exposed injuries upper extremity. The aim this study was assess number types hands and/or wrists in regular climbers. conducted on group 468 criterion for inclusion regularity trainings, training internship at least 1 year minimum difficulty co...

annular pancreas (ap) is a rare congenital abnormality in which pancreatic tissue completely surround the duodenum. presentation of ap in adulthood is very rare and obstructive jaundice is one of the uncommon manifestations of ap in adults. herein; we reported a 47 years old woman who presented with icterus, midcommon bile duct stricture and annular pancreas. she was diagnosed as pancreas cance...
