Adequate Pulmonary Stenosis Allowed Long-Term Survival in a Patient With Unoperated Single Ventricle

![Figure][1] [![Graphic][3] ][3][![Graphic][4] ][4] A 60-year-old woman with unoperated single ventricle (SV) had been uneventful until infective endocarditis occurred. Only 9 cases of unoperated SV in patients older than 60 years have been reported. Previous examinations had

ASSESSMENT OF RIGHT ATRIAL PRESSURE IN CHILDREN WITH CONGENITAL HEART DISEASE: SIMULTANEOUS THREE-DIMENSIONAL ECHOCARDIOGRAPHY AND CATHETERIZATION STUDY

Echocardiographic estimation of right atrial pressure (RAP) using inferior vena cava (IVC) dimensions and its collapsibility in children remains controversial. To access IVC measurements without the influence of translation of IVC into another plane during respiration is essential but challenging.

Tricuspid valve chordae tendineae as protective filter to prevent massive pulmonary embolism

Although several cases of thrombus-in-transit associated with pro-thrombotic conditions have been reported (1-3), a transit thrombus located in the right ventricular (RV) cavity is extremely rare (4,5). Here, we report a case of nephrotic syndrome (NS) with a RV thrombus-in-transit that threatened to cause a fatal pulmonary embolism (PE).

Obstructed bi-leaflet prosthetic mitral valve imaging with real-time three-dimensional transesophageal echocardiography

Real‐time three‐dimensional transesophageal echocardiography (RT3D‐TEE) can provide unique visualization and better understanding of the relationship among cardiac structures. Here, we report the case of an 85‐year‐old woman with an obstructed mitral prosthetic valve diagnosed promptly by RT3D‐TEE, which clearly showed a leaflet stuck in the closed position. The opening and closing angles of the valve leaflets measured by RT3D‐TEE were compatible with those measured by fluoroscopy. Moreover, RT3D‐TEE revealed, in the ring of the prosthetic valve, thrombi that were not visible on fluoroscopy. RT3D‐TEE might be a valuable diagnostic technique for prosthetic mitral valve thrombosis.
