Very happy to share the publication of my PhD research in @ccijournal !
We report a case series of mitral M-TEER in patients with advanced heart failure, performed at @hcpa_oficial, and discuss clinical and anatomical factors that increase procedural complexity in this setting.

🚨 Just published! We validated an ultrasound-based score combining VExUS + LUS to guide decongestion in acute heart failure. A step forward toward more precise, ultrasound-driven management. Proud of our team! Congrats Henrique!

Our FASTEMI study is now published! 🎉
This quick and practical POCUS protocol in STEMI can be truly decisive: it guides management, identifies critical differential diagnoses, and achieves a 97% negative predictive value for in-hospital mortality.

Proud to present our research at #TCT2025 introducing a POCUS-based approach with - LUV classification - to enhance SCAI shock staging and mortality prediction in STEMI.

Great weekend at the SOCERGS Congress! Grateful for the chance to share a bit of our work — and honored to receive the Best Oral Presentation award once again.

🚨 The Killip classification alone-is it still enough? 🩺

🔹 LUS is already a reality in acute STEMI evaluation.
🔹 Adding LUS to LVOT-VTI (LUV classification) enhances prediction of mortality and cardiogenic shock.

🚨 New paper from our research group!

📊 In 85 TAVI patients, pre-procedural LUS showed more advanced disease in “wet lungs” — but did not predict death or HF at 12 months in this setting.

🚨 Just published! The LUV classification (LVOT-VTI + lung ultrasound) outperformed other ultrasound protocols in predicting in-hospital mortality and cardiogenic shock within 24h in STEMI patients

First registry of TAVI in patients treated exclusively by the Brazilian Public Health System (SUS). An important data now that the procedure is being incorporated into SUS.
