Why This Case Matters
Kulen, a 46-year-old professional pilot from Mongolia, faced the possibility of never flying again after persistent atrial fibrillation failed to respond to two electrical cardioversion attempts. His case became an opportunity for an experienced Chinese electrophysiology team to bring cryoballoon ablation expertise directly to Mongolia. For international patients seeking advanced atrial fibrillation treatment in China, ChinaCureLink can help coordinate specialist assessment and access to experienced cardiac teams.

Patient Background
Kulen had been diagnosed with persistent atrial fibrillation approximately one year before the procedure. He sought treatment at a major hospital in Ulaanbaatar, but two attempts at electrical cardioversion failed to restore a lasting normal rhythm.
For a professional pilot, persistent atrial fibrillation carried consequences far beyond the symptoms of an irregular heartbeat. The condition threatened his ability to continue flying, making successful rhythm treatment particularly important to his future.
The arrival of a specialist team from China offered another treatment option: cryoballoon catheter ablation, a minimally invasive procedure that uses a catheter inserted through a blood vessel to treat areas responsible for abnormal electrical signals in the heart.
The Care Team and Approach
The procedure was performed by a Chinese cardiac electrophysiology team led by Dr. Wei Jun (pseudonym), supported by Dr. Lin Hao (pseudonym) and Dr. Zhang Rui (pseudonym).
Cryoballoon ablation is designed to interrupt abnormal electrical signals that maintain atrial fibrillation. A catheter is introduced through a vein, advanced into the heart, and positioned to treat targeted areas. Pulmonary vein isolation is a central part of the procedure because abnormal electrical activity originating around the pulmonary veins can contribute to atrial fibrillation.
In Kulen's case, the team first isolated the pulmonary veins. His rhythm did not immediately return to the expected normal pattern, so the team carried out additional mapping and modified the atrial ablation strategy. Cryoablation was then performed at additional areas involving the bases of the atrial appendages, the left atrial ridge, and the anterior wall of the left atrium.
The additional treatment restored normal heart rhythm, and the entire procedure was completed in approximately 50 minutes.
The case also formed part of a wider training and technology-transfer program. After Kulen's procedure, the Chinese team worked alongside local doctors as they performed cryoballoon ablation on five additional patients with atrial fibrillation.
Treatment Timeline/ Process
Before Treatment — Mongolia
Approximately one year before the procedure: Kulen was diagnosed with persistent atrial fibrillation.
He underwent two attempts at electrical cardioversion at a major hospital in Ulaanbaatar.
Both attempts failed to restore the desired rhythm.
As a professional pilot, the unsuccessful treatment placed his ability to continue flying at risk.
He became a candidate for evaluation by a specialist Chinese cardiac electrophysiology team.
Cryoballoon Ablation in Mongolia
A Chinese cardiac team traveled more than 2,200 kilometers from Shanghai to Ulaanbaatar to provide specialist treatment and training.
Kulen underwent femoral venous access, allowing the treatment catheter to be guided into the heart.
Intracardiac mapping identified the areas requiring treatment.
The team performed pulmonary vein isolation using cryoballoon ablation.
When the rhythm did not immediately return to normal, the team performed additional atrial mapping and cryoablation.
Normal heart rhythm was restored during the procedure.
Total procedure time was approximately 50 minutes.
Training and Recovery
The Chinese team subsequently assisted local physicians in performing cryoballoon ablation on five additional patients with atrial fibrillation.
Kulen and the other patients recovered in hospital.
September 18: Kulen and the other treated patients were discharged.
Outcome
The 50-minute procedure restored Kulen's heart rhythm after two unsuccessful electrical cardioversion attempts.
He recovered in hospital and was discharged on September 18, alongside the other patients treated during the program.
The wider program also established a pathway for local physicians to perform cryoballoon ablation themselves, with the Chinese team providing hands-on training and procedural support. The collaboration therefore extended beyond one patient's treatment to building local expertise in advanced atrial fibrillation care.
How ChinaCureLink Can Help International Patients to Access This Treatment
Kulen's case demonstrates how specialist expertise in atrial fibrillation can cross borders — with an experienced Chinese cardiac team bringing advanced catheter-ablation knowledge directly to Mongolia.
For international patients who need specialist assessment for persistent or difficult-to-treat atrial fibrillation, ChinaCureLink can help coordinate access to experienced cardiac teams in China. The process can include medical-record review, specialist matching, treatment planning, hospital coordination, and logistical support for patients traveling internationally for care.
A specialist assessment is essential because the appropriate ablation strategy depends on the patient's type of atrial fibrillation, heart structure, previous treatment, medical history, and overall health.
Get a Second Opinion Before Fly to China
For suitable cases, ChinaCureLink can then coordinate an online consultation with the specialist to discuss the technical treatment details directly. The purpose is to help the patient understand which treatment option and which specialist center may be most appropriate before making an international treatment decision.

Frequently Asked Questions
Can cryoballoon ablation treat persistent atrial fibrillation after electrical cardioversion has failed?
Cryoballoon ablation can be considered for selected patients with atrial fibrillation, including some patients with persistent atrial fibrillation. Whether it is appropriate depends on the individual patient's heart condition, rhythm history, previous treatments, and specialist assessment.
How can an international patient arrange atrial fibrillation ablation in China?
The process generally begins with a review of medical records, ECG or rhythm-monitoring results, cardiac imaging, and previous treatment history. ChinaCureLink can coordinate the case review and help connect eligible patients with experienced cardiac electrophysiology teams in China.
How long does recovery take after cryoballoon ablation?
Recovery varies between patients and depends on the procedure, underlying heart condition, and post-procedure monitoring. Patients require specialist follow-up after ablation to monitor their heart rhythm and manage medications and any potential complications.
