Transpericardial access is an important procedure in clinical cardiac electrophysiology. The ability to access the pericardial space is critical for rapid drainage in acute cardiac tamponade and is also increasingly used to perform epicardial mapping and ablation of a range of ventricular and atrial arrhythmias.1–3 The seminal description of this technique by Sosa described the use of the left ...

The radiological evaluation of the anterolateral femoral head is an essential tool for the assessment of the cam type of femoroacetabular impingement. CT, MRI and frog lateral plain radiographs have all been suggested as imaging options for this type of lesion. The alpha angle is accepted as a reliable indicator of the cam type of impingement and may also be used as an assessment for the succes...

Anterior subtalar dislocations are extremely rare. To our knowledge, only four cases have been reported in detail in the literature. A diagnosis of anterior subtalar dislocation should be confirmed by an anteroposterior view radiograph because lateral subtalar dislocation always includes some anterior displacement of the mid-foot. We report a case of anterior subtalar dislocation confirmed by b...

Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...

Ligamentous instability of the ankle joint can be confirmed by radiographs taken in two planes. The place of the anteroposterior varus stress view is established, but the lateral view which shows anterior subluxation of the talus is frequently omitted. The anatomical significance of the two stress views has been determined by dividing different components of the lateral ligament of 20 cadaveric...

four tylenchid species, namely, aglenchus agricola, malenchus exiguus, psilenchus curcumerus, and p. terextremus are reported from iran. the iranian population of a. agricola is characterized by 542-659 µm long body, 10-12 µm long stylet, excretory pore at 70-87 µm distance from anterior end, prominent lateral fields, with four lines, tail of 170-198 long, and rare males with 15-20 µm long spic...

OBJECTIVE To determine the diagnostic value of 2 intraoral bisecting angle radiographic views in comparison with periodontal probing for the assessment of periodontal attachment of the canine teeth in dogs. STUDY POPULATION 466 canine teeth from 117 dogs. PROCEDURE Periodontal probing measurements were recorded, and clinical attachment levels (CAL) were calculated at the mesial, buccal, dis...

OBJECTIVE This study compared data on the blood flow velocity in the internal carotid artery, which was obtained using the optical flow method (OFM) with digital subtraction angiography (DSA) and the time-of-flight (TOF) technique using magnetic resonance angiography (MRA). MATERIALS AND METHODS Images were obtained from 12 cerebrovascular patients who underwent both brain DSA and MRA imaging...
