Early pregnancy diagnosis in cows using corpus luteum blood flow analysis based on colour Doppler ultrasonography and mRNA analysis Open
The CDUS-based CLBF analysis on day 20 after TAI can be potentially used for the early identification of non-pregnancy status in dairy cows and MX2 could be a potential mRNA candidate for the identification of pregnancy in cows. Further st…

Acute and chronic effects of levosimendan in the ZSF1 obese rat model of heart failure with preserved ejection fraction Open
Heart failure with preserved ejection fraction (HFpEF) is a syndrome characterized by impaired cardiovascular reserve in which therapeutic options are scarce. Our aim was to evaluate the inodilator levosimendan in the ZSF1 obese rat model …

Pregnancy in patients submitted to arterial embolization for uterine leiomyomas Open
The study showed that 58.7% of the women who underwent UAE and expressed an interest in becoming pregnant were able to achieve pregnancy, with a 13.6% loss rate. However, further studies are needed to elucidate the key variables that contr…

Interventional cardiology in cancer patients: A position paper from the Portuguese Cardiovascular Intervention Association and the Portuguese Cardio-Oncology Study Group of the Portuguese Society of Cardiology Open
The field of Cardio-Oncology has grown significantly, especially during the last decade. While awareness of cardiotoxicity due to cancer disease and/or therapies has greatly increased, much of the attention has focused on myocardial systol…

Transcatheter Tricuspid Valve Replacement: Illustrative Case Reports and Review of State-of-Art Open
Tricuspid regurgitation (TR) is one of the most common heart valve diseases, associated a with poor prognosis since significant TR is associated with an increased mortality risk compared to no TR or mild regurgitation. Surgery is the stand…

Left ventricular pacing with a temporary pacemaker: Case report Open
We report a case of temporary pacemaker lead malposition in the left ventricle crossing the interventricular septum (IVS). The majority of described cases occur due to a patent foramen ovale and are frequently incidental findings. A course…

Myocardial dysfunction in Takotsubo syndrome: More than meets the eye? Open
While both TTS and STEMI feature significantly impaired global systolic function, we found a regional pattern of worse basal longitudinal strain and a lower basal/apical ratio in the former. These suggest generalized myocardial impairment …

Myocardial dysfunction in Takotsubo syndrome: More than meets the eye? Open
Introduction: Takotsubo syndrome (TTS) is characterized by transient left ventricular (LV) dysfunction, typically mimicking an anterior wall myocardial infarction (MI), without obstructive coronary artery disease. In the few published repo…

Modulation of Iris Sphincter and Ciliary Muscles by Urocortin 2 Open
Urocortin 2 (UCN2) is a peptide related to corticotropin-releasing factor, capable of activating CRF-R2. Among its multisystemic effects, it has actions in all 3 muscle subtypes. This study’s aim was to determine its potential role in two …

P2495Cardiac rehabilitation: don't forget the ones that went away Open
Background: Cardiac rehabilitation is recommended in patients after heart valve surgery despite limited evidence.The CopenHeartVR trial found a positive effect on physical capacity after 4 months weeks, but no effect on mental health.Howev…

P3270Cardiac catheterization after CABG with BIMA grafting: independent predictors and mid-term bypass viability Open
Background: Coronary artery bypass graft (CABG) patency is an important variable, but rarely studied as the main outcome.The best use of bilateral internal mammary artery (BIMA) grafting regarding configuration type or combination with sap…

P417 Non-invasive assessment of liver fibrosis by transient elastography and AST to ALT ratio in patients with Crohn's disease treated with methotrexate Open
Background: One of the most feared concerns about the use of methotrexate (MTX) is the risk of developing chronic liver injury. Transient elastography is a simple, non-invasive method for estimating liver fibrosis. AST to ALT ratio (AST/AL…
