Your typical atrial flutter ablation checklist
Keep this guide with your medication plan and discharge instructions.
Before you arrive
- Read the medication and fasting plans. Your team must complete any intentional blanks before you follow them.
- Complete scheduled tests. Bring your current medicine list and allergy information.
- Arrange an adult driver and someone to stay with you after sedation.

UNDERSTANDING YOUR PROCEDURE
Typical atrial flutter ablation
Before and after cavotricuspid isthmus (CTI) ablation
What the procedure does
Typical atrial flutter is a fast electrical loop in the right upper heart chamber. Ablation treats a narrow area called the cavotricuspid isthmus (CTI) to interrupt that loop. This guide covers typical right-sided flutter, not atypical left-atrial flutter or AF ablation.
On the day
After local numbing, catheters are passed through veins, usually at the groin, into the heart. The team maps the circuit, creates a line of treatment and checks that electrical signals cannot cross it. Sedation or anesthesia is tailored to the procedure. You rest flat while the access sites seal; discharge is often the same day, though some patients stay overnight.
Benefits and risks
The procedure can prevent typical flutter from returning, but recurrence is possible and atrial fibrillation may occur afterward. Risks include bleeding, vessel injury, infection, heart perforation or fluid around the heart, clots or stroke, and rarely injury to normal conduction requiring a pacemaker. Serious complications and death are uncommon but possible.
Getting ready
Medicines and fasting
Take your prescribed blood thinner exactly as directed before the procedure. Report any missed doses in the preceding 3 weeks before proceeding, because imaging or rescheduling may be needed. The procedure-day plan below must be completed if any dose is to change. After successful flutter ablation, continue prescribed anticoagulation for at least 4 weeks and longer until your team tells you otherwise. Do not stop it just because the rhythm feels normal.
Blood thinner / antiplatelet plan
Food and drink plan
SGLT2 medicines
GLP-1 medicines
Any separate written instructions for insulin or other diabetes medicines take priority; do not apply a general morning-medicine instruction to them.
Recovering at home
What to expect
Mild improving groin soreness, bruising and tiredness are common. Some extra beats may occur. Sustained racing or a newly irregular rhythm needs assessment; successful flutter ablation does not prevent every other rhythm problem.
Follow-up
Appointment / return-to-work details:
When to get help
Call 911
- Severe or sudden chest pain or trouble breathing, fainting, or stroke symptoms such as facial droop, arm weakness or trouble speaking.
- Heavy or continuing bleeding despite firm pressure, or rapidly growing painful swelling with weakness or faintness. Lie down, keep firm pressure on the bleeding site and have someone call 911.
- A cold, pale, numb or severely painful leg, especially on the catheter-access side.
Do not drive yourself. Do not wait for a message or remote-monitor response.
Contact the clinic the same day
Increasing access-site swelling, redness, warmth, drainage or pain; fever or chills; a sustained return of racing heartbeat or new persistent palpitations.
For warning symptoms after hours, use the contact route below. If you cannot reach the team and symptoms are worsening, seek urgent assessment. Use 911 for the severe symptoms listed above.
