Quantification of atrial cardiomyopathy disease severity by electroanatomic voltage mapping and cardiac magnetic resonance imaging.

Introduction: Atrial late gadolinium enhancement (Atrial-LGE) and electroanatomic voltage mapping (Atrial-EAVM) quantify the anatomical and functional extent of atrial cardiomyopathy. We aimed to explore the relationships between, and outcomes from, these modalities in patients with atrial fibrillation undergoing ablation.

Methods: Patients undergoing first-time ablation had disease severities quantified using both Atrial-LGE and Atrial-EAVM.

Quantifying the impact of shape uncertainty on predicted arrhythmias.

Background: Personalised computer models are increasingly used to diagnose cardiac arrhythmias and tailor treatment. Patient-specific models of the left atrium are often derived from pre-procedural imaging of anatomy and fibrosis. These images contain noise that can affect simulation predictions.

Applications of multimodality imaging for left atrial catheter ablation.

Atrial arrhythmias, including atrial fibrillation and atrial flutter, may be treated through catheter ablation. The process of atrial arrhythmia catheter ablation, which includes patient selection, pre-procedural planning, intra-procedural guidance, and post-procedural assessment, is typically characterized by the use of several imaging modalities to sequentially inform key clinical decisions. Increasingly, advanced imaging modalities are processed via specialized image analysis techniques and combined with intra-procedural electrical measurements to inform treatment approaches.

Sagliker syndrome in patients with secondary hyperparathyroidism and chronic renal failure: Case report.

Introduction: Sagliker described craniofacial, skeletal, neurologic and soft tissue abnormalities in patients with secondary hyperparathyroidism with end-stage chronic renal disease. This unique entity has been attributed to delay in treatment of renal insufficiency. As of 2012 sixty cases have been reported.

[Use of percutaneous needles in the feasability of single-port laparoscopic cholecystectomy].

Introduction: The usefulness of percutaneous needles (PN) to replace traditional assistance ports in mini-invasive techniques with a single port is analyzed and their feasibility for conducting a single port laparoscopic cholecystectomy (SPLC) is demonstrated.

Material And Methods: A retrospective, linear and descriptive study covering 2,431 patients with a diagnosis of acute and non-acute gallbladder disease has been conducted. The patients underwent a single port laparoscopic cholecystectomy using some type of PNs, replacing the assisting ports used in traditional laparoscopic cholecystechtomy (TLC).

Transvaginal single port cholecystectomy.

Background: Transvaginal cholecystectomy encourages researchers to develop new hybrid or pure techniques for natural orifice surgery. We present an approach that combines flexible endoscopes, rigid instruments, and percutaneous needles.

Methods: A 26-year-old female patient with cholelithiasis underwent a single-port culdolaparoscopy cholecystectomy at "Hospital Regional Poza Rica" (Poza Rica, Mexico) on July 2008.
