Popis: Abstract Background A patent foramen ovale (PFO) is a risk factor for cryptogenic stroke (CS), and interventional therapy for PFO can reduce the recurrence rate of CS. However, interventional therapies are primarily guided by X-ray imaging, and data on regular post-surgical follow-up with the transthoracic ultrasound foaming test (UFT) are rare. Thus, this study aimed to assess the short-term (12 months) results of PFO occlusion guided by transoesophageal echocardiography (TEE) and the results of regular UFTs. Methods Clinical records, echocardiographic data, and UFT results of 75 patients who underwent interventional therapy for PFO and CS were retrospectively analysed. The patients were grouped according to their preoperative UFT results: group A (n = 21), small volume of right-to-left shunts; group B (n = 22), moderate volume of right-to-left shunts; and group C (n = 32), large volume of right-to-left shunts. All patients were treated with an Amplatzer occluder under TEE guidance. UFT follow-up was conducted regularly until 12 months after surgery. Results No significant differences in preoperative data, length of hospital stay, or operative time were noted between the groups (p > 0.05). The length of the PFO and diameter of the occluder differed between the groups as follows: group A = group B
