Throwback Thursday - Coratomic Pacemakers

Coratomic, a PM manufacturer based in Indiana, PA, was 1 of 3 American companies producing atomic PMs in the 1970s (hence the name).

The enthusiasm for plutonium PMs faded just as fast as it rose, in part due t…https://t.co/0dvkhVW4Az

What's Driving this AF?

Patient s/p several AF ablation elsewhere presented with persistent AF > 1 year.

Baseline bipolar map showed patchy low voltage areas with extreme fragmentation on the PW and anterior septum (green balls and red dots).

The Cow Jumped Over the Moon

Hey diddle diddle,
The cat and the fiddle,
The Green jumped over the Blue;
The little dog laughed
To see such sport,
And the LA ran away with the CS

Why some P waves are so Fragmented

In AF patients, not infrequently we find very fragmented P waves in NSR. Here's a biatrial map in a patient s/p prior PVI, correlating intracardiac activation to 12L P waves.

As we've been taught in school, the termina…https://t.co/YYzqI2KUcq

One of the coolest cases in recent memory. Don't blink or you'll miss it.

KYC in the RVOT/PA Area

While focusing on our 3D maps during an ablation, it is easy to forget the important structures outside of the map. That's when ICE comes in handy.

In this case of RVOT PVC, the successful site (blue dot) was at the level of pulm…https://t.co/IqzRl52uHS

Throwback Thursday - 2013 Ablation

Here is an old case of roof flutter ablation from my younger days. How we actually accomplished anything for so many years without contact force, ablation index, or deflectable sheath still blows my mind.

Have you ever seen an SVC valve?

The Eustachian valve is also known as the IVC valve. But have you ever seen an SVC valve?

A search in the literature reveals what is termed "supernumerary valves." I find one case report https://t.co/8tyM9DgHXb

Another SVC Tachycardia
