Intra- and extra- cardiac shunt can coexist. Differentiate mainly via flow pattern not cycle timing.
•PFO: transient/intermittent bolus which can be late if RAP>LAP occurs late.
•Transpulmonary: continuous trail of bubbles; can occur early for example in liver cirrhosis patients with large stroke volumes.

Patients with greater spontaneous echo contrast (SEC) grade displayed a higher incidence of thromboembolic events and DRT, and combined SEC grade and #AFib type independently predicted these events. Further research is needed https://t.co/bzuuFwYCGG #JACCCEP

Heart failure evidence update 2026

Major developments include the emergence of non-steroidal mineralocorticoid receptor antagonists and incretin-based therapies for heart failure (HF) with mildly reduced and preserved EF, the validation of rapid guideline-directed medical therapy optimization strategies in acute HF, and new evidence supporting digitalis glycosides in HF patients with reduced EF. Device-based care has evolved with transcatheter edge-to-edge repair for valvular heart disease

Our state-of-the-art review on pulmonary HTN due to left heart ds (group 2) now publ in JACC. Poor prognosis, esp when pre-capillary PH develops (PVR >2 WU - CpcPH). No specific Rx exist. We're starting the PULSE-LHD trial of PA denervation in 500 pts with group 2 PH and CpcPH.

We believe this will be a great step further in defining sex specific thresholds in valvular heart disease. Congratulations Pilar Lopez Santi !

👦👧De pequenino é que se aprende a salvar vidas...

📖 O livro infantil “Vou-te salvar! Suporte Básico de Vida” ensina as crianças a realizar manobras de suporte básico de vida (SBV) de forma divertida e educativa. A história do Duarte e dos seus primos mostra como todos podemos fazer a diferença em momentos críticos.

No âmbito do projeto de Literacia para a Saúde "E.S.T.A.R e viver bem na freguesia" e para assinalar o Dia Mundial da Criança a 1 de junho, este livro será distribuído numa ação de sensibilização a decorrer na Mexilhoeira Grande, no concelho de Portimão.

Just dropped in CASE:
- 77W with AF-RVR and stroke; referred for LAAO device.

Major Teaching Point:
- ALWAYS review entire baseline TEE to exclude OTHER CVA causes
