[Global longitudinal strain impairment factors in heart failure with preserved ejection fraction].

Introduction: In heart failure with preserved left ventricular ejection fraction (LVEF), global longitudinal strain (GLS) has a diagnostic and prognostic value. This study aimed to identify the factors associated with the alteration of strain in heart failure with preserved left ventricular ejection fraction.

Methods: This study was carried out in patients with heart failure and preserved LVEF seen in the echocardiography laboratory of the DAX hospital center from 1 January to 31 October 2022.

[The role of transesophageal echocardiography (TEE): case study conducted at the Dax Hospital Center].

The purpose of this study is to assess the role of transesophageal echocardiography at the Dax Hospital Center based on indications, patients´ profile, results, cost-effectiveness and consistency with prescribers´ expectations. We conducted a retrospective, cross-sectional, descriptive and analytical study at the Cardiovascular Laboratory of the Dax Hospital Center from January 2016 to December 2018. The study included 434 exams out of 460 requested.

Cerebral paradoxical embolism associated with patent foramen ovale and idiopathic venous thromboembolism in a 31-year-old patient.

Paradoxical embolism is the passage of venous thrombi into the arterial circulation through a pulmonary or intracardiac shunt. We report the management of a 31-year-old patient who initially presented with chest pain and right brachiofacial paresis. A diagnosis of paradoxical cerebral embolism associated with a spontaneous venous thromboembolism and a patent foramen ovale was made.
