Atrial dilatation in Atrial fibrillation : A query with multiple twists!

Dr. S. Venkatesan MD

Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It When atrial fibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. We know atrial flutters can be confined to one atrium.

Empirical superior vena cava electrical isolation guided by quantitative ablation index improves outcomes of radiofrequency catheter ablation for paroxysmal atrial fibrillation

Open Heart

Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups.

Boston Scientific Initiates AVANT GUARD Clinical Trial to Evaluate FARAPULSE Pulsed Field Ablation System as First-Line Treatment for Persistent Atrial Fibrillation

DAIC

Patients in the study will be randomized to undergo pulmonary vein isolation (PVI) and left atrial posterior wall ablation using the FARAPULSE PFA System, or receive AAD treatment, and followed for three years. The randomized AVANT GUARD trial will enroll more than 500 patients diagnosed with persistent AF at up to 75 sites globally.

PO-01-025 PULMONARY ARTERY PRE-MAPPING AND RADIOFREQUENCY ABLATION: A NOVEL METHOD TO FACILITATE LEFT ATRIAL ROOF LINE BLOCK

HeartRhythm

Complete and durable block across the left atrial (LA) roof can be integral to ablation of persistent atrial fibrillation (AF) and atypical atrial flutter (AFl). The right pulmonary artery (RPA) is in close proximity to the LA roof, and may provide a vantage for epicardial LA roof mapping and ablation.

Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?

Dr. Smith's ECG Blog

male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Bedside ultrasound showed volume depletion and no pulmonary edema.

EP News: Case Reports

HeartRhythm

Pulmonary vein isolation (PVI) remains the cornerstone of atrial fibrillation (AF) ablation. In patients with more advanced AF subtypes, atypical atrial flutter, and extensive atrial myopathy, additional linear ablation is often required; however, durable block of these remains challenging.

A novel ablation strategy for recurrent atrial fibrillation: Fractionated signal area in the atrial muscle ablation 1?year follow?up

Journal of Cardiovascular Electrophysiology

FAAM ablation successfully decreased the recurrence rate of atrial tachyarrhythmia compared with conventional non-PV foci ablation. Abstract Introduction Treatment of recurrent atrial fibrillation (AF) is sometimes challenging due to non-pulmonary vein (PV) foci. The RHYTHMIA system was used to perform all the procedures.
