RESUMO
Stress echocardiography (SE) is a well established and valid technique, widely used for the diagnostic evaluation of patients with ischemic and nonischemic cardiac diseases. This statement of the Echocardiography Working Group of the Hellenic Society of Cardiology summarizes the consensus of the writing group regarding the applications of SE, based on the expertise of their members and on a critical review of present medical literature. The main objectives of the consensus document include a comprehensive review of SE methodology and training-which focus on the preparation, the protocols used, the analysis of the SE images, and updated, evidence-based knowledge about SE applications on ischemic and nonischemic heart diseases, such as in cardiomyopathies, heart failure, and valvular heart disease.

Intimal sarcomas are a very rare medical entity and usually arise from the pulmonary artery or the thoracic aorta. Sarcomas should be considered in the differential diagnosis in patients with suspected mitral valve disease. Echocardiography should be performed as early as possible to establish a prompt diagnosis and management.
RESUMO
Myxoma is the most common primary cardiac tumor and is usually located in the left atrium. Clinical manifestation relies in large part on the size, location, and architecture of the tumor. There are many reports in the literature of cardiac myxomas causing syncope, embolism, even myocardial infarction. We present a rare case of a patient who underwent urgent surgical resection of a large left atrial myxoma mimicking mitral stenosis. The postoperative course of the patient was uncomplicated. One year after surgery, the patient is asymptomatic and disease-free.
RESUMO
We present a case of pacemaker lead dislodgment in an 83-year-old patient with a pacemaker infection. Initially, the generator and the proximal part of the leads were removed, and the remaining leads were severed and abandoned. Twenty-five days later, dislodgment of both abandoned leads and systemic infection were documented. The leads were then surgically removed without further complications.

Beta-thalassemia major (beta-TM), patients, asymptomatic and with preserved left ventricular ejection fraction (LVEF) were studied echocardiographically. Group A (26 patients), on deferiprone (L1) and deferoxamine (DFO) combination therapy (L1: 80 +/- 27 mg/kg/day, DFO: 160 +/- 87 mg/kg/week) and group B (35 patients) on DFO monotherapy (240 +/- 40 mg/kg/week) for the last 2 years were compared. Another group, C (14 patients), switched to L1 (74 +/- 15 mg/kg/day) plus DFO (158 +/- 48 mg/kg/week) for 20-30 months, was prospectively studied for 2 years. In group A, MRI T2* values were increased and improved in group C during follow-up. The LVEF was better in group A than in group B, while such an improvement was also detected in the group C follow-up study. The Tissue Doppler study E' velocity and E/E' ratio was not different. Similarly, in the group C follow-up no significant change in E/E' ratio was detected. It seems that although LVEF significantly improves with combined therapy, diastolic function indexes do not show a similar change.
