The electrocardiography was continuously recorded for the evaluation of the atrial electromechanical delay during echocardiography, and parameters such as intra-right atrial conduction time (IRCT), intra-left atrial conduction time (ILCT), and interatrial
conduction time (IACT) were calculated.
However, daily activities such as lifting, coughing, vomiting, and pushing which increase intrathoracic (ITP) and intraabdominal pressure may reverse the interatrial
pressure gradient, creating a temporary right-to-left shunt.
Doppler tissue evaluation of intra-atrial and interatrial
electromechanical delay and comparison with P-wave dispersion in patients with mitral stenosis.
Israeli medical company V-Wave Ltd stated on Wednesday that it has admitted the first patients under its global, pivotal study of its proprietary, minimally invasive implanted interatrial
shunt device for treating NHYA Class III and ambulatory Class IV symptomatic heart failure (HF), the leading cause of hospitalisations in many countries.
Two morphological left atria with complete absence of the interatrial
septum were visualised.
Transthoracic and transesophageal echocardiography (Figures 1a-1b) and computed tomography angiography (Figures 1c-1d) revealed a large oval-shaped, slightly calcified left atrial mass, contiguous to the atrial roof near the right superior pulmonary vein orifice, adherent to the interatrial
While pregnant patients with EA are usually acyanotic, those with interatrial
shunting can develop shunt reversal and cyanosis in pregnancy.
(16,21) Fat emboli can also reach the systemic circulation, affecting other organs, because of the patency of the foramen ovale in the interatrial
septum, the existence of pulmonary arteriovenous microfistulas, and the deformation of the fat microglobules that cross the pulmonary capillaries.
Three-dimensional transesophageal echocardiography (3D-TEE) is particularly valuable during transcatheter occlusion of interatrial
andinterventricular septal defects.
The solid component, a 5 x 2.3 [cm.sup.2] mass, had invaded the basal half of the interatrial
septum and the cystic component was found to protrude into the left atrium (Figure 1(d)).
Atrial septal defects were created in adult female black-headed mutton sheep (n = 20; mean body weight, 45 [+ or -] 10 kg) by transseptal puncture and subsequent balloon dilation of the interatrial
