7. Two and three dimensional echocardiography for pre-operative assessment of mitral valve regurgitation - Quader, Nishath; Rigolin, Vera H
Mitral regurgitation may develop when the leaflets or any other portion of the apparatus becomes abnormal. As the repair techniques for mitral valve disease evolved, so has the need for detailed and accurate imaging of the mitral valve prior to surgery in order to better define the mechanism of valve dysfunction and the severity of regurgitation. In patients with significant mitral valve disease who require surgical intervention, multiplane transesophageal echocardiogram (TEE) is invaluable for surgical planning. However, a comprehensive TEE in a patient with complex mitral valve disease requires great experience and skill. There is evidence to suggest that 3D...

8. Diastolic wall strain: a simple marker of abnormal cardiac mechanics - Selvaraj, Senthil; Aguilar, Frank G; Martinez, Eva E; Beussink, Lauren; Kim, Kwang-Youn A; Peng, Jie; Lee, Daniel C; Patel, Ateet; Sha, Jin; Irvin, Marguerite R; Arnett, Donna K; Shah, Sanjiv J

11. Tissue Doppler, Strain and Strain Rate in ischemic heart disease “How I do it” - Mada, Razvan O; Duchenne, Jürgen; Voigt, Jens-Uwe
Echocardiography is the standard method for assessing myocardial function in patients with ischemic heart disease. The acquisition and interpretation of echocardiographic images, however, remains a highly specialized task which often relies entirely on the subjective visual assessment of the reader and requires therefore, particular training and expertise. Myocardial deformation imaging allows quantifying myocardial function far beyond what can be done with sole visual assessment. It can improve the interpretation of regional dysfunction and offers sensitive markers of induced ischemia which can be used for stress tests. In the following, we recapitulate shortly the pathophysiological and technical basics and explain in...

12. Relationship between epicardial adipose tissue, coronary artery disease and adiponectin in a Mexican population - Yañez-Rivera, Teresa G; Baños-Gonzalez, Manuel A; Ble-Castillo, Jorge L; Torres-Hernandez, Manuel E; Torres-Lopez, Jorge E; Borrayo-Sanchez, Gabriela

20. 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,...
