DIAVAL is an expert system for the diagnosis of heart diseases, including several kinds of data, mainly from echocardiography. The first part of this paper is devoted to the causal probabilistic model which constitutes the knowledge base of the expert system in the form of a Bayesian network, emphasizing the importance of the OR gate. The second part deals(More)
Intravenous leiomyomatosis is a very rare uterine neoplasm, characterized by histological benignity. In some cases, it could extend through the ovaric or iliac veins up to the vena cava and the right chambers of the heart. We report a patient with symptoms of right heart failure, who was diagnosed by transesophagic echocardiography of intravenous(More)
This study describes the clinical, anatomic, echocardiographic, and Doppler features of 13 patients with mitral valve aneurysms. Eleven patients had definitive criteria for infective endocarditis. Transesophageal echocardiography was superior to conventional echocardiography in detecting and assessing aneurysms. Patients with heart failure required surgery.(More)
Background Transesophageal echocardiography is superior to transthoracic echocardiography in detecting left-sided valvular vegetations. There are no data on the value of transesophageal echocardiography in the diagnosis of infected transvenous permanent pacemakers. Methods and Results Transthoracic and transesophageal echocardiography was performed in 10(More)
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(More)
Heart involvement in echinococcal disease is rare, but it is more infrequent the location of cysts in the right ventricle. We report a case of a male 35 years old with hydatid cysts located in the right ventricle. The condition was diagnosed by two-dimensional echocardiogram performed after the rupture of the cysts leading to massive pulmonary embolism and(More)
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.
Observational assessment of behavior is a core measurement tool in modern psychological research and practice. Despite the importance of observational assessment and the tremendous amount of research devoted to refining and enhancing the methodological foundations of these tools, current best practices still bear a strong resemblance to those from three(More)
