Vena de Marshall. 🫀⚡️
🔶️La vena de Marshall es un remanente de la vena cardinal izquierda embrionaria que discurre entre la orejuela izquierda y las venas pulmonares izquierdas.
🔶️Lo importante es lo que contiene:
⚡ Fascículo de Marshall (tejido muscular arritmogénico).
⚡ Plexos autonómicos simpáticos y parasimpáticos.
⚡ Conexiones epicárdicas protegidas por grasa.
🔶️Por ello participa en los 3 pilares para generar FA:
🔸️Trigger: genera extrasístoles que inician FA.
🔸️Sustrato: favorece circuitos de reentrada y gaps epicárdicos.
🔸️Modulación autonómica: la estimulación de sus plexos puede inducir FA.
🔶️ La vena de Marshall no es un simple vestigio embrionario; es una estructura neuro-muscular capaz de iniciar, mantener y perpetuar la FA. Por eso se ha convertido en un objetivo terapéutico clave en la ablación moderna de la FA persistente (la infusión con etanol surge como nueva opción). 🫀⚡

Some patients with vagally mediated AF can benefit most from cardioneuroablative effect and may not need full PVI

Some of them may not even require any ablation in the left atrium

See my comment in the subthread.
In patients with RBBB, narrowing of the S-wave in lead I with an S/QRS ratio<0.56 is associated with increased need for PPM, even after adjusting for QRSd.

CAAN-AF Trial #CHRD @adelaide87018

Our previous meta-analysis of observational studies suggested CRT patients with AF had a significant 58% reduction in all-cause mortality with AV node ablation - https://t.co/rLbkUhqZLX

Three years ago, I was asked to speak @westernAFib on whether PFA will obviate the need for epicardial therapies. As a field, we need to collectively understand when and how often PFA is transmural and durable.

Congrats to @Innovate_JJ and team on publishing our observations with simultaneous epi mapping.

🔎 Webinar Spotlight: Imaging in PFA

In this clip, Prof Josef Kautzner explains why fluoroscopy alone is insufficient in pulsed field ablation. A 2D view misses the third dimension, particularly along the ridge between the appendage and left veins, where reconnection often occurs.

Catheter position may look acceptable on fluoro, yet lack posterior wall contact or ridge alignment. Signals and intracardiac echo reveal what fluoroscopy cannot.

This part of the New Horizons In Atrial Fibrillation series, where experts discuss optimizing imagery strategy in PFA.
