The great debate at #las2026 - left atrial appendage closure: expanding evidence or expanding enthusiasm? A winning argument by @drjohnm and a very balanced and considered rebuttal by Tim Betts. More agreement than disagreement! @ShouvikHaldar @MillbrookMed

Sir William Osler, 1849-1919, renowned as the father of modern medicine, famously instructed medical students to: "Listen to your patient, he is telling you the diagnosis." It's a simple dictum, but the foundation of the way Osler revolutionised healthcare by insisting that doctors step away from their desks and focus on their patients. Everyone longs for functioning, joined-up NHS IT, @jamesmurray_ldn (though not via Palantir) - but to suggest, as you have in this post, that history-taking is a tedious irrelevance is to completely misunderstand the nature of medicine. That first conversation between doctor and patient is a close, shrewd, vital therapeutic encounter. As we listen, we observe, appraise, distil. Invariably, the diagnosis can be made. But history-taking, like the rest of medicine, is the marriage of science with humanity. It treats patients as people, not as objects with disease. Through your time, care and attentiveness in history-taking, you communicate something vital to a patient - that they matter and that you care. Please never forget that healthcare is not a production line of objects, it's an enterprise built on relationships, with humanity at its core. Medical history-taking is its bedrock.
I know how distressing it is for patients to repeat their medical history over and over. And the effort it takes for NHS staff to get the information they need. We'll join up this fragmented system, helping clinicians give safer, co-ordinated care.

This is an excellent thread 🧵 on the comparative effects of warfarin and DOACs on coagulation factors, and the reasons that warfarin is more effective than DOACs in preventing thrombus on mechanical valves...
1/14 Why can't you use direct oral anticoagulants (DOACs) in patients with mechanical valves (MVs)? DOACs have been one of the most important advances in my career. And yet, the presence of a MV is one of the few contraindications. The reason highlights the unique nature of thrombus formation in those with a MV and provides insights into the evolution of human hemostasis.

🌍 New insights in cardiac resynchronisation therapy for adults with a systemic right ventricle 💡🫀 A new international multicentre study has just been published, exploring the impact of cardiac resynchronisation therapy (CRT) in adults with a systemic right ventricle (sRV) — a growing and uniquely complex patient population. 📄 Fusco et al., Heart (2025) 🔬 What makes this study remarkable? This is the largest cohort ever reported, including patients with ccTGA and d-TGA after atrial switch. Thanks to a robust propensity-matched analysis, it provides the strongest real-world evidence to date on CRT in this challenging anatomy. 📉 Key findings Despite expectations and past small-scale studies, CRT did not improve survival or event-free survival in adults with an sRV. Even after adjusting for confounders, CRT remained associated with worse outcomes, likely reflecting advanced disease stage and suboptimal timing at the moment of implantation. Moreover, only a minority of patients achieved significant QRS narrowing—highlighting how challenging true resynchronisation can be in this substrate. ⚙️ Why does this matter? Patients with an sRV face increasing rates of heart failure as they age. Understanding which therapies truly work — and which need refinement — is essential to guide future care. This study underscores the need for: ➡️ Better patient selection ➡️ Earlier identification of candidates ➡️ Optimised pacing strategies adapted to sRV physiology ➡️ Exploration of conduction system pacing (CSP) as a more physiological alternative 🔌✨ 🚀 Looking ahead While CRT, as currently applied, may not deliver meaningful benefit in this population, the field is moving fast. Advances in CSP and refined timing may soon reshape how we approach electrical therapy in adults with congenital heart disease. 🔗 A milestone paper that pushes the field forward and reminds us how essential tailored, anatomy-specific strategies are in ACHD. #Cardiology #ACHD #SystemicRV #CRT #HeartFailure #CongenitalHeartDisease #Innovation #Research doi.org/10.1136/heartjnl-202…
