  • left atrial
  • The analysis included 110 studies comprising 7946 patients (79% male, 59.8±0.5 years, 43% left atrial enlargement, 49% heart disease, 16±12 months follow up). (ahajournals.org)

  • In this study, a novel approach allowing for use of a liquid refrigerant capable of achieving lower nadir temperatures was tested in a canine model with cavo-tricuspid isthmus (CTI) and left atrial (LA) ablation. (biomedsearch.com)
  • In all animals, long linear (from 4-8 cm) transmural atrial lesions were observed on gross and histological examination in the left atrial roof, septum and mitral isthmus, and across the cavo-trisucpid isthmus. (biomedsearch.com)
  • Results: Left atrial effective refractory period increased dose and the primary outcome measure increased dose and plasma concentration dependently, with a mean increase of 55 milliseconds in dose group 3. (diva-portal.org)
  • It can evaluate right and left atrial size, as well as the size and function of the right and left ventricles, and this information facilitates diagnosis of valvular heart disease, left ventricular hypertrophy (LVH), and pericardial disease. (medscape.com)
  • The main hazard of cardioversion is embolization of cerebral or peripheral arteries from thrombus that may have accumulated in the left atrial appendage. (yumpu.com)
  • An alternative is to perform early cardioversion provided that transoesophageal echocardiography can be performed and shows no evidence of thrombus in the left atrial appendage. (yumpu.com)
  • The clinical variables associated with the occurrence of AF after catheter ablation of AFL were female, a history of AF before AFL ablation, body mass index (BMI), and left atrial abnormality. (rcvmonline.com)
  • anatomy
  • The 2D and 3D ICE were useful for visualizing the complex anatomy of the CTI and identifying the anatomical characteristics of the CTIs refractory to ablation therapy. (springer.com)
  • The clarity with which the detailed regional anatomy needed for ablation procedures being offered depends on the imaging modality but is generally excellent. (onlinejacc.org)
  • right ventricular
  • The recordings were obtained with a 9F, 9-MHz ICE catheter from the right ventricular outflow tract to the inferior vena cava by pulling the catheter back 0.3 mm at a time under guidance with echocardiographic imaging in a respiration-gated manner. (springer.com)
  • mechanism
  • Despite the presence of congenital heart disease treated with prior cardiac surgery and AFLs with variable atrial cycle lengths, the CTI-dependent mechanism underlies approximately half of the sustained, symptomatic AFLs. (biomedsearch.com)
