Abstract

Abstract:

Objective

To observe the safety and efficacy of solo transcatheter closure of Patent Foramen Ovale (PFO) guided solely by transthoracic echocardiography (TTE).

Methods

A total of 25 cases were retrospectively included who underwent the solo transcatheter closure of PFO guided by TTE in Peking University Third Hospital from December 2018 to December 2019. They were 20 females and 5 males with average age of (42.3±7.8) years. TTE was performed immediately after percutaneous closure. The follow-up interviews were conducted at 1 month, 3 months, and 6 months after the procedure, respectively. There were 6 patients with cryptogenic stroke (RoPE score＞6) and 19 patients with obstinate migraine. The presence of PFO was confirmed by preoperative transesophageal echocardiography (TEE). The diameter of PFO was 2-3 mm and the diameter of tunnel was 4-8 mm. The contrast-enhanced transcranial doppler (cTCD) was 2-3 grade.

Results

All patients were successfully treated with the solo transcatheter closure of PFO guided by TTE. The mean procedural time (from puncture to sheath removal) was (32.1±7.5) mins. During the operation, 3 cases presented vagal reflex and 2 cases developed transient ventricular arrhythmia, which disappeared after conservative treatment. All patients were discharged the next day after operation without complications, e.g. pericardial effusion, peripheral vascular injury, or cardiac perforation. During the follow-ups, no patients suffered from pericardial effusion, occluder malposition, residual shunt, recurrence of headache and stroke. The cTCD is normal.

Conclusion

The solo transcatheter closure of PFO guided by TTE is an effective procedure with high successful rate and low rate of complications.
