Aims: We present the experience and long-term results of intracardiac echocardiography (ICE)-guided closure of ostium secundum atrial septal defects (ASDs) in two Italian centers and investigate its systematic applicability as the gold standard in routine clinical practice. Methods: We retrospectively evaluated all consecutive patients who underwent an ASD percutaneous closure procedure from March 2008 to February 2020. All patients underwent a preprocedural transesophageal echocardiography (TEE) evaluation. The closures were carried out under fluoroscopic and ICE guidance. A follow-up visit was performed at 1, 3 and 12 months, followed by telephone evaluations approximately every 2 years. Results: Sixty-six patients (29% male individuals), mean age 43 ± 16 years, were treated. In 15 cases, the TEE defect diameter was less than 10 mm, and in 8 of these patients, the ICE intraprocedural sizing increased the maximum diameter by more than 5 mm. Sizing balloon of the defect was performed in 51 cases; 2 patients received an ASD 38 mm device. Eight patients had multiple defects; in three of these, it was necessary to apply two devices. Four patients showed nonsignificant residual shunt; no complications related to the use of ICE were observed. One patient presented the migration of the ASD device into the abdominal aorta, percutaneously retrieved with a snare. No major complications were recorded during the entire follow-up period. Conclusion: This study confirms that ICE monitoring during ASD percutaneous closure is well tolerated and effective; it might be achievable as a routine gold standard by operators willing to use ICE systematically in all transcatheter closure interventions of interatrial communications.

Abstract

Aims: We present the experience and long-term results of intracardiac echocardiography (ICE)-guided closure of ostium secundum atrial septal defects (ASDs) in two Italian centers and investigate its systematic applicability as the gold standard in routine clinical practice. Methods: We retrospectively evaluated all consecutive patients who underwent an ASD percutaneous closure procedure from March 2008 to February 2020. All patients underwent a preprocedural transesophageal echocardiography (TEE) evaluation. The closures were carried out under fluoroscopic and ICE guidance. A follow-up visit was performed at 1, 3 and 12 months, followed by telephone evaluations approximately every 2 years. Results: Sixty-six patients (29% male individuals), mean age 43 ± 16 years, were treated. In 15 cases, the TEE defect diameter was less than 10 mm, and in 8 of these patients, the ICE intraprocedural sizing increased the maximum diameter by more than 5 mm. Sizing balloon of the defect was performed in 51 cases; 2 patients received an ASD 38 mm device. Eight patients had multiple defects; in three of these, it was necessary to apply two devices. Four patients showed nonsignificant residual shunt; no complications related to the use of ICE were observed. One patient presented the migration of the ASD device into the abdominal aorta, percutaneously retrieved with a snare. No major complications were recorded during the entire follow-up period. Conclusion: This study confirms that ICE monitoring during ASD percutaneous closure is well tolerated and effective; it might be achievable as a routine gold standard by operators willing to use ICE systematically in all transcatheter closure interventions of interatrial communications.
