Abstract
Purpose of review: To provide an overview of fluoroscopy-free transcatheter atrial septal defect (ASD) closure and introduce a simplified approach that avoids pulmonary vein instrumentation.
Recent findings: Since the first reported fluoroscopy-free ASD closure 24 years ago, only a few small series have described this technique. We present a simplified and less cumbersome approach to encourage wider adoption of the fluoroscopy-free method to suitable ASD anatomy.
Results: Fluoroscopy free ASD closure was performed in 9 patients using the conventional technique (Group 1) and 23 patients using our simplified approach of direct placement of the device into the defect (Group 2). Median age and weight were 28 years, 53 kg in Group 1 (range: 5-52 years, 22-88 kg) and 36 years, 66 kg in Group 2 (range: 4-76 years, 16-115 kg). Devices were successfully implanted in all patients, with a median device size of 21 mm (Group 1: 9-36 mm, Group 2: 10-33 mm). Procedural time was 47 min for Group 1 and 35 min for Group 2 (p = 0.09). Length of hospital stay was similar in both groups. There were no acute or long-term complications and no need for reintervention. Transcatheter ASD closure without the use of fluoroscopy using the simplified approach is safe and effective, offers a shorter procedure duration and minimises instrumentation within the left atrium and pulmonary veins. Patient selection is key and with greater experience, this procedure may be applicable to a wider selection of ASD anatomy.
期刊介绍：
The aim of this journal is to provide timely perspectives from experts on current advances in cardiovascular medicine. We also seek to provide reviews that highlight the most important recently published papers selected from the wealth of available cardiovascular literature.
We accomplish this aim by appointing key authorities in major subject areas across the discipline. Section editors select topics to be reviewed by leading experts who emphasize recent developments and highlight important papers published over the past year. An Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. We also provide commentaries from well-known figures in the field.
