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.

Case ReportsTransesophageal echo probe compression of an aberrant right subclavian artery.
Transesophageal echocardiography (TEE) is frequently used in the operating room to assess surgical repairs in children with congenital heart disease. Complications from the procedure are unusual, but the potential for TEE probe compression of normal and abnormal posterior vascular structures has been recognized. We report a case of TEE probe compression of an aberrant right subclavian artery in a patient undergoing repair of an atrioventricular septal defect.

Case ReportsCor triatriatum dexter in an adult diagnosed by transesophageal echocardiography: a case report.
Cor triatriatum dexter is a rare congenital heart malformation in which a persistent right sinus venosus valve divides the right atrium into two chambers. Before echocardiography, this anomaly has been rarely diagnosed before surgery or death. ⋯ A definitive diagnosis of cor triatriatum dexter with associated heart defects was best made by transesophageal echocardiography at 47 years of age. Subsequent surgical intervention confirmed all of the echocardiographic findings and successful correction of the defects was performed.

Case ReportsDisseminated coccidioidomycosis with rapid progression to effusive-constrictive pericarditis.
This case reports coccidiomycosis presenting as pericarditis with tamponade rapidly progressing to effusive-constrictive pericarditis and death over 72 hours. Coccidiomycosis pericarditis is a rapidly progressing disease requiring early and complete pericardiectomy to avoid the hemodynamics of constriction. ⋯ We review the literature and discuss therapy and management. Coccidiomycosis is often clinically unsuspected and unrecognized by the health care worker unfamiliar with the disease process.
