Background Ebstein’s anomaly (EA) is a rare but clinically important congenital heart disease with potential affection of right ventricular(RV), right atrial (RA), left ventricular (LV) and left atrial (LA) function that may play a role in heart failure development. Thus, we sought to assess quantitative atrial and ventricular function in EA with CMR feature tracking, and to correlate changes i...
INTRODUCTION It is generally known that positive pressure ventilation is associated with impaired venous return and decreased right ventricular output, in particular in patients with a low right atrial pressure and relative hypovolaemia. Altered lung mechanics have been suggested to impair right ventricular output in COPD, but this relation has never been firmly established in spontaneously bre...
A 58-year-old man with hypertensive cardiovascular disease and atrial flutter underwent electrophysiologic studies, including multiple intra-atrial recordings and atrial stimulation. Although the surface ECG suggested the presence of atrial flutter, intra-atrial recordings demonstrated the presence of (1) sinus-like rhythm localized to an area of approximately 5 mm in and around the region of t...
conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...
In patients with sickle cell disease, thrombotic microangiopathy is a rare complication. Also in sickle cell disease, intracardiac thrombus formation without structural heart diseases or atrial arrhythmias is a rare phenomenon. We herein describe a 22-year-old woman, who was a known case of sickle cell-βthalassemia, had a history of recent missed abortion, and was admitted with a vaso-occlusive...
cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium through restrictive opening to the low-pressure, dista...
