Ablation, Atrial Flutter and Tachycardia

Association of typical atrial flutter and cavotricuspid isthmus ablation on clinical recurrence after cryoballoon ablation for atrial fibrillation

Frontiers in Cardiovascular Medicine

DECEMBER 14, 2023

Typical atrial flutter commonly occurs in patients with atrial fibrillation (AF). Limited information exists regarding the effects of concurrent atrial flutter on the long-term outcomes of rhythm control. The data were obtained from a multicenter registry of cryoballoon ablation for AF ( n = 2,689).

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

When mutiple atrial tachycardias coexist, ablation of an individual isthmus may lead to a seamless transition (without significant changes in surface ECG or coronary sinus activation) to a second rhythm. The isthmus block could go unnoticed leading to continued unnecessary ablations.

Outcomes of ablation with the FARAPULSE PFA System – a nonthermal treatment in which electric fields selectively ablate heart tissue – will be compared to outcomes following use of anti-arrhythmic drug (AAD) therapy, which is commonly prescribed for patients living with persistent AF. The company now anticipates U.S. Circulation.

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.

Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. There are no P waves preceding the QRS complexes, and no clear flutter waves.

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. The ECG was interpreted as showing atrial flutter with 2:1 conduction. Answer : The ECG above shows a regular wide complex tachycardia. The heart rate could be compatible with that of a 2:1 conducted atrial flutter.

In all probability, this dilation is a form of atrial tachycardia and atrial cardiomyopathy. However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. We know atrial flutters can be confined to one atrium.

PEARL # 3: Atrial Flutter with 1:1 AV conduction is rare! Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.
