Echocardiographic imaging techniques with subcostal and right parasternal longitudinal views in detecting sinus venosus atrial septal defects.
Sinus venosus atrial septal defects are frequently missed and difficult to visualize with conventional two-dimensional echocardiographic views. Using modified subcostal and right parasternal longitudinal views, nine patients were found to have a sinus venosus atrial septal defect. ⋯ Partial anomalous pulmonary venous return was diagnosed in seven patients using these views. The combination of subcostal and right parasternal longitudinal imaging views will improve the detection of sinus venosus atrial septal defects.

Review Case ReportsEchocardiographic diagnosis of right and left sinus of Valsalva aneurysms dissecting into the ventricular septum.
We report a case of dissection of the ventricular septum by two aneurysms of the right and left coronary sinuses of Valsalva. Transthoracic and transesophageal echocardiography allowed accurate preoperative assessment and postoperative evaluation.

Review Case ReportsTransesophageal echocardiographic features and management of retained intracardiac air in two patients after surgery.
Intracardiac residual air after open-heart surgery may carry a significant risk of embolization with associated morbidity and death. We hereby report two cases of retained intracardiac air detected in an unusual location with transesophageal echocardiography in the superior aspect of the left atrium after completion of standard air-evacuation procedures. Characteristic echocardiographic features and the impact on immediate management are described along with a review of the literature.

Case ReportsValvulitis involving a bioprosthetic valve in a patient with systemic lupus erythematosus.
A 37-year-old man with systemic lupus erythematosus, who underwent an aortic valve replacement with a Carpentier-Edwards porcine valve for severe aortic insufficiency, was admitted to the hospital with pulmonary edema. Transesophageal echocardiography revealed severe aortic insufficiency arising from partial dehiscence of the valve sewing ring, as well as centrally from the valve cusp. ⋯ After replacement of both valves, the patient had a stormy postoperative course with recurrent communications between the left ventricle and atrium requiring multiple surgeries and eventually died. This case illustrates the severity of valvulopathy and ensuing complications that can affect patients with systemic lupus erythematosus and demonstrates that the valvulopathy can affect bioprosthetic valves, a finding that has significant implications as to the type of valve replacement in these patients.

Clinical TrialEvaluation of pulmonary vein stenosis by transesophageal echocardiography.
Pulmonary vein stenosis was diagnosed by transesophageal echocardiography in five patients who underwent the study for different clinical indications. Stenosis was encountered in the right upper pulmonary vein in two patients, the right lower pulmonary vein in two patients, and at the confluence of the left pulmonary veins in one patient. In only one patient was the diagnosis suspected on transthoracic echocardiography. ⋯ Peak flow velocity of 0.8 m/sec appears to provide the best separation between normal and stenosed pulmonary veins. We conclude that pulmonary vein stenosis is associated with increased flow velocity and turbulence and deformity of the flow signal. Transesophageal echocardiography is a powerful tool in the study of pulmonary vein stenosis.
