@syamkumarmd Ugh, I noticed only the second screen without the native QRS preceding the pacing 😳 Sorry!

[Piotr Denysiuk @denyfication]

@syamkumarmd Excellent example !

W Lublinie w 2024 otwarto nową kardiochirurgię

w Lubelskim są tylko 2, a NFZ w 2024 wydało 35mln na leczenie pacjentów poza województwem

Ale kolejny rok NFZ nie daje jej kontraktu (brak kasy)

UE dało właśnie 280mln na jej rozbudowę xD

Wyśmienicie

☢️STAR may silence VT, but long-term safety is still being defined. We report the first delayed ventricular septal defect occurring 2 years after STAR for VT, with dosimetric concordance at the VSD site
⚡️Long-term follow-up data are needed

In patients with persistent atrial fibrillation, first-line treatment with pulsed field ablation reduced the recurrence of atrial arrhythmias at 12 months as compared with antiarrhythmic drugs. Full AVANT GUARD trial results: https://t.co/milHy26ojJ

[European Society of Cardiology @escardio]

The European Society of Cardiology is deeply saddened by the passing of Professor Eugene Braunwald, one of the most influential figures in the history of cardiovascular medicine, who died on 22 April 2026, aged 96.

“Professor Braunwald was the leading cardiologist of his time. His vision and innovation changed the trajectory of cardiovascular medicine. He had a rare ability to see what the field needed next, and then to build the science and rigorous evidence leading to better care. He set a standard for intellectual honesty and mentorship, giving generations of clinicians and researchers the confidence to aim higher.” Professor Thomas F. Lüscher, @ESC_President

Professor Braunwald’s work helped define how cardiovascular disease is understood and treated. His legacy endures in the patients whose lives have been saved by evidence-based cardiovascular care, and in the people he inspired to pursue medicine with integrity and purpose https://t.co/IUtVSlbzph

@Arritmias_HRC Beautiful as always. Is there another loop around ivc?

[Naczelna Izba Lekarska @NaczelnaL]

Ministerstwo Zdrowa @MZ_GOV_PL planuje zamach na bezpieczeństwo polskich pacjentów. W ramach pozornej oszczędności, MZ chce zlikwidować staż podyplomowy lekarzy.

Studenci, młodzi lekarze i doświadczeni specjaliści są zgodni, że staż jest krytycznym momentem kształcenia każdego lekarza i nie wyobrażamy sobie jak można go zlikwidować z powodów finansowych. To na nim lekarz i lekarz dentysta ma możliwość nabrać doświadczenia przed samodzielną praca. Nawet najlepsze studia nigdy tego nie zastąpią, zwłaszcza w sytuacji kiedy na polskich uczelniach coraz częściej przypada 20 studentów na 1 pacjenta, a zamiast pacjenta jest plastikowy fantom.

Likwidacja stażu, to więcej błędów lekarskich zwłaszcza w stomatologii i dziedzinach zabiegowych, odebranie kadry mniejszym szpitalom, rok szybsze wypchniecie młodych lekarzy z NFZ na rynek prywatny. W czyim interesie są opracowywane te zmiany? Bo na pewno nie naszych pacjentów.

Wzywamy Rząd Pana Premiera @donaldtusk @PremierRP do zatrzymania tych ogromnie niebezpiecznych dla pacjentów zmian planowanych przez Ministerstwo Zdrowia

This is the final lesion set.

Important lessons for us from this case - always double check what you cut out and don’t rely only on 3d maps.
As suggested by @ftrae entrainment from distal cs in this case would have helped a lot!

[Piotr Denysiuk @denyfication]

A 62 YOF with a history of surgical correction of partial AVSD and mitral cleft, after CTI ablation+scar homogenization. AT with CL 260ms and prox->distal activation on CS. Here is the initial RA map.

What do you do next?

@Arritmias_HRC @javadm20 @syamkumarmd @ftrae

[Piotr Denysiuk @denyfication]

We thought about going to Aorta, but first we started 🔥 at the gap in the WADL near the mitral valve - nothing. We then proceded with RF @ IAS earliest activation site from LA/RA and then at anterior mitral line between the low voltage areas- still nothing.

[Piotr Denysiuk @denyfication]

We carefully reevaluated the map and removed any anatomical planes to see if we didn’t miss anything - any there it was. One 🔥 closer to the mitral annulus terminated the arrhythmia.
