Evaluation of Left Ventricular Structure and Function using 3D Echocardiography

Adrienn Ujvári¹, Bálint Károly Lakatos¹, Márton Tokodi¹, Alexandra Fábián¹, Béla Merkely¹, Attila Kovács¹

¹Heart and Vascular Center, Semmelweis University

In this article, we provide a step-by-step acquisition and analysis protocol for the volumetric assessment and speckle-tracking analysis of the left ventricle by 3D echocardiography, particularly focusing on practical aspects that maximize the feasibility of this technique.

Echocardiographic Evaluation of Atrial Communications before Transcatheter Closure

Andrea Ágnes Molnár^*1, Pál Ábrahám^*1, Béla Merkely¹, Sándor Nardai¹

¹Heart and Vascular Center, Semmelweis University

Transthoracic (TTE) and transesophageal (TEE) echocardiography represent the basic imaging tools for interatrial septum examination. Three dimensional (3D) TEE provides incremental information in the assessment of the interatrial septum. Further advanced echocardiography techniques using speckle tracking echocardiography are applied for sensitive volumetric and functional assessment of the heart chambers.

The overall goal of the current study is to present the techniques of induction of myocardial infarction (MI) and post-myocardial infarction heart failure (post-MI HF) in closed-chest, adult Göttingen minipigs and the characterization of post-MI HF model in Göttingen minipigs as compared to Landrace pigs.
