8. Which method of left atrium size quantification is the most accurate to recognize thromboembolic risk in patients with non-valvular atrial fibrillation? - Faustino, Ana; Providência, Rui; Barra, Sérgio; Paiva, Luís; Trigo, Joana; Botelho, Ana; Costa, Marco; Gonçalves, Lino

9. The potential value of integrated natriuretic peptide and echo-guided heart failure management - Scali, Maria Chiara; Simioniuc, Anca; Dini, Frank Lloyd; Marzilli, Mario
There is increasing interest in guiding Heart Failure (HF) therapy with Brain Natriuretic Peptide (BNP) or N-terminal prohormone of Brain Natriuretic Peptide (NT-proBNP), with the goal of lowering concentrations of these markers (and maintaining their suppression) as part of the therapeutic approach in HF. However, recent European Society of Cardiology (ESC) and American Heart Association/ American College of Cardiology (AHA/ACC) guidelines did not recommend biomarker-guided therapy in the management of HF patients. This has likely to do with the conceptual, methodological, and practical limitations of the Natriuretic Peptides (NP)-based approach, including biological variability, slow time-course, poor specificity, cost and venipuncture,...

10. Need for a standardized protocol for stress echocardiography in provoking subaortic and valvular gradient in various cardiac conditions - Petkow Dimitrow, Pawel; Cotrim, Carlos; Cheng, Tsung O
(Semi) supine exercise testing has an established role in the evaluation of patients with valvular heart disease and can help clinical decision making. Stress echocardiography has the advantages of its wide availability, low cost, and versatility for the assessment of disease severity. However, exercise-induced changes in valve hemodynamics, left ventricular outflow obstruction and pulmonary artery pressure depended on load variation. Changing position from supine to upright rapidly decreases load conditions for the ventricles. Therefore several cardiac centers have proposed exercise stress echocardiography in the upright position with gradient monitoring sometimes also in post-exercise recovery. Doppler measurement of subaortic gradient has...

11. Diverse geometric changes related to dynamic left ventricular outflow tract obstruction without overt hypertrophic cardiomyopathy - Cha, Jung-Joon; Chung, Hyemoon; Yoon, Young Won; Yoon, Ji Hyun; Kim, Jong-Youn; Min, Pil-Ki; Lee, Byoung-Kwon; Hong, Bum-Kee; Rim, Se-Joong; Kwon, Hyuck Moon; Choi, Eui-Young

12. How I do it: judging appropriateness for TTE and TEE - Fonseca, Ricardo; Marwick, Thomas H
The increasing cost of healthcare is a widespread international problem to which the cost of imaging has been an important contributor. Some imaging tests are ordered inappropriately and contribute to wasted use of resources. Appropriate use criteria have been developed in the USA in order to guide test selection, but there are a number of problems, including the evidence base for these criteria and the steps that can be taken to change physician practice. A restrictive approach to test ordering is difficult to fit to the nuances of clinical presentation and may compromise patient care. We propose an alternative approach...
