Long-Term Follow-Up of Transthoracic Echocardiography-Guided Transcatheter Closure of Large Atrial Septal Defects (≥ 30 mm) Using the SHSMA Occluder

Quality of life in pregnancy after percutaneous closure of atrial septal defect guided by transthoracic echocardiography

PURPOSE

We evaluated quality of life (QoL) in pregnant women who underwent transthoracic echocardiography-guided percutaneous closure of atrial septal defect (ASD).

METHODS

A total of 45 pregnant women underwent transthoracic echocardiography-guided percutaneous closure of ASD. We assessed QoL using the 36-Item Short Form Survey (SF-36) and compared results between pre- and post-procedure patients, as well as between those with ASD and healthy women in their second and third trimesters of pregnancy.

RESULTS

All patients showed improved right ventricular function and were classified as Class I, post-procedure. Mean SF-36 scores of the post-procedure group were better on all sub-scales than those of the pre-procedure group (p < 0.05), with the exception of role-emotional and mental health. Mean SF-36 scores for the pre-procedure group were also lower on all sub-scales than those of healthy pregnant controls (p < 0.05), with the exception of role physical, role emotional, and mental health. There was no difference between the post-procedure group and healthy pregnant controls. In a subgroup analysis, scores were better in some dimensions (social functioning and role emotional) for post-procedure patients in the 31-40 years of age group and the group on their second or third pregnancies than those of the 20-30 years of age group and the group on their first pregnancies (p < 0.05).

CONCLUSION

After closure of ASD, QoL in pregnant women was improved. In a subgroup analysis, the younger women and those on their first pregnancy performed more poorly in some dimensions (social functioning and role emotional); this suggested that these groups should receive more proactive intervention.

Midazolam for conscious sedation in transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography

OBJECTIVES

To investigate the safety and feasibility of midazolam for conscious sedation in transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography.

METHODS

A retrospective analysis was performed on 55 patients who underwent transcatheter device closure of atrial septal defects from October, 2019 to May, 2020. All patients received intravenous midazolam and local anesthesia with lidocaine to maintain sedation. A group of previous patients with unpublished data who underwent the same procedure with general anesthesia was set as the control group. The relevant clinical parameters, the Ramsay sedation scores, the numerical rating scale, and the post-operative satisfaction questionnaire were recorded and analyzed.

RESULTS

In the midazolam group, the success rate of atrial septal defect closure was 98.2%. Hemodynamic stability was observed during the procedure. None of the patients needed additional endotracheal intubation for general anesthesia. Compared with the control group, the midazolam group had no statistically significant differences in the Ramsay sedation score and numerical rating scale scores. Patients in the midazolam group experienced more post-operative satisfaction than those in the control group.

CONCLUSIONS

Conscious sedation using midazolam is a safe and effective anesthetic technique for transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography.

Late embolisation of an atrial septal occluder device in the abdominal aorta

Percutaneous closure of secundum atrial septal defect (sASD) - which is the most common in adult congenital heart disease - is considered to be the first treatment option but can involve early and late complications. We report on the late embolization of a device to the abdominal aorta, 12 months after successful percutaneous closure of sASD. A 63-year-old woman, who suffered from stomach ache, was found to have an ASD occluder device in her abdominal aorta. Although surgical intervention to remove the embolisation may be considered, medical follow-up and re-intervention of percutaneous closure may be feasible for inappropriate cases.
