[A large aneurysm of the interatrial septum simulating an atrial mass. Its identification by transesophageal echocardiography].

A patient with a large atrial septal aneurysm mimicking a right atrial mass is reported. Diagnosis was correctly obtained by transesophageal echocardiography. Clinical importance of this entity and usefulness of transesophageal echocardiography in its diagnosis is discussed.

Diagnosis of mitral valve myxoma by transesophageal echocardiography.

Mitral valve myxomas are rare. We report a patient with a mitral myxoma arising from the posterior mitral leaflet in whom transthoracic echocardiography revealed equivocal findings. However, transoesophageal echocardiography provided accurate relevant anatomical information including the size, morphological characteristics, and tumour attachment point.

[Papillary muscle rupture. Diagnosis with transesophageal echocardiography].

Two patients with acute myocardial infarction and papillary muscle rupture are presented. The diagnosis of papillary muscle rupture was made by transesophageal echocardiography. The transesophageal echocardiographic findings and the usefulness of this technique in the diagnosis of papillary muscle rupture are described.

[Usefulness of Doppler color echocardiography in the treatment of femoral pseudoaneurysms].

Four patients with a femoral pseudoaneurysm formation after a therapeutic cardiac catheterization are presented. The diagnosis was made by color-Doppler-ultrasound after clinical suspicion. The repair of this complication was performed using color flow ultrasound-guided compression of the pseudoaneurysm neck.

Right atrial diverticulum and hypertrophic cardiomyopathy.

This report describes the case of a young man with a right atrial diverticulum and hypertrophic cardiomyopathy who died suddenly. The relationship of congenital diverticulosis of the heart with hypertrophic cardiomyopathy is discussed.

Transesophageal echocardiography in right-sided endocarditis.

Objectives: Our aim was to determine the diagnostic value of transesophageal echocardiography in right-sided endocarditis.

Background: Recent studies have demonstrated that transesophageal echocardiography is superior to transthoracic echocardiography in the detection of vegetations associated with left-sided endocarditis. Its diagnostic value in right-sided endocarditis has not been established.

Transesophageal echocardiographic monitoring of percutaneous mitral balloon valvulotomy.

This study was designed to evaluate the usefulness of performing transesophageal echocardiography (TEE) during percutaneous mitral balloon valvulotomy (PMBV). TEE was performed in 35 consecutive patients with symptomatic severe mitral stenosis during PMBV (group A). Another group of 27 patients with mitral stenosis who underwent PMBV without TEE was used for comparison (group B).

[Echocardiography with intravenous dipyridamole infusion in the assessment of ischemic cardiopathy. A comparison with the stress test].

Background: Diagnosis of ischemic cardiomyopathy by noninvasive methods is a challenge for the clinician. Echocardiography with intravenous administration of dipyridamole has been proposed as an alternative to exercise stress test in this setting.

Methods: Intravenous administration of dipyridamole (0.

[The usefulness of transesophageal echocardiography in the diagnosis of pulmonary thromboembolism].

Three cases with suspected pulmonary artery embolism are presented, in which transesophageal echocardiography showed a mass in the right pulmonary artery consistent with thrombus. The relevant diagnostic contributions of transesophageal echocardiography are discussed.

[Mitral valve aneurysm. Its diagnosis by transesophageal echocardiography].

Aneurysm of the mitral valve is a rare complication of infectious endocarditis. We report a 65-years-old woman with left heart failure and mitral regurgitation secondary to a mitral valve aneurysm. The diagnosis was made by transesophageal echocardiography.

Eustachian valve endocarditis.

M mode and cross sectional echocardiography showed a highly mobile globular pedunculated mass(3.0 cm long with a maximum diameter of i.5 cm) attached to the eustachian valve in a heroin addict with staphylococcal endocarditis.

[Role of intraoperative echo-Doppler color echocardiography in cardiac surgery. Preliminary study].

Intraoperative echocardiography with Doppler color flow imaging technique can provide the surgeon with an immediate and direct assessment of cardiac anatomy and function. To determine the utility of this recent technique, we have examined 15 patients pre, per, and postoperatively with Doppler color flow imaging. The intraoperative study was performed before and after cardiopulmonary bypass.
