An 18-year-old woman presented to our institution with fever, bilateral flank pain, headache and photophobia. She had a previous atrial septal defect (ASD) closure device inserted at the age of 9 years. Blood cultures on admission were positive forCorynebacterium diphtheriae, and transoesophageal echocardiogram (TOE) revealed an echodensity associated with the ASD closure device, most consistent with a vegetation. She was treated for infective endocarditis with 6 weeks of intravenous benzylpenicillin, and follow-up TOE showed resolution of the echodensity. To our knowledge, no cases ofC. diphtheriaeendocarditis of an ASD closure device have previously been reported.

Atrial fibrillation (AF) is the most commonly treated arrhythmia in clinical practice and is often found in association with an atrial septal defect (ASD). However, ASD closure rarely confers complete arrhythmia control. A 23-year-old man presented to our center with frequent episodes of palpitations. AF was documented in 12-lead electrocardiography, and echocardiography showed a secundum-type ASD, 14 mm in size, with a significant left-to-right shunt. ASD closure was performed successfully with an ASD occluder device with no residual shunting. During follow-up, the patient experienced several episodes of AF. Thirteen months after the ASD closure, cryoballoon pulmonary vein isolation was done successfully with no complications. During a 12-month follow-up, he had no symptoms or AF recurrences, and echocardiography showed no residual shunting. This study showed that cryoballoon pulmonary vein isolation could be performed successfully without residual shunts in patients with ASD closure devices.

Abstract Background closure of atrial septal defect (ASD) has emerged as the treatment of choice for the majority of defect. The biodegradable ASD closure device is a novel, absorbable device made of poly-L_latic acid (PLLA). This study evaluates the feasibility, safety and effectiveness of PLLA biodegradable ASD closure device in a swine model and for the first time in human. Objective The study reports on the 24- and 36- month follow-up results of PLLA device implanted in a swine model and the first-in- man experience with 6-month follow-up. Method Preclinical study was done in a swine ASD model. In a clinical setting, 5 pediatric patients with a secundum ASD who a clinically left-to-right shunt were enrolled in our center. Percutaneous ASD closure procedure with PLLA device was performed with fluoroscopic and transcatheter echocardiography (TTE) guidance. Procedure results and clinical outcomes at 1 day, 30 days, 3 months and 6 months after closure procedure were analyzed. Results 24- and 36-month follow-up results of preclinical study demonstrated that the PLLA device exhibited good endothelialization and degradability in a swine model. In clinical study, device implantation was successfully achieved in all of 5 patients (median age, 3.6 years; range, 3.1–6.5 years). The mean ASD size was (13.4±2.4)mm (range, 10–16mm). The mean pulmonary-to-systemic blood flow ratio (Qp:Qs) was (1.7±0.2):1 with a range of 1.5:1 to 2.0:1. The mean procedure time and the mean fluoroscopy time were (36.2±11.3) and (6.4±1.0)minutes, respectively. There was no evidence of short-term complications related to the device or the delivery system. No device dislodgement, significant aortic valve or mitral valve regurgitation, new onset cardiac arrhythmia, or other adverse events were reported.

Purpose. The Occlutech Figulla occluder has been proven safe and effective at midterm follow-up after percutaneous atrial septal defect (ASD) closure. We describe the safety and efficacy at long-term follow-up in adults. Methods. All consecutive adult patients that underwent ASD closure between 2008 and 2015 were included. All complications were registered. Residual left-to-right shunt (LRS) was diagnosed using color-Doppler transthoracic echocardiography (TTE). Right-to-left shunting was diagnosed using contrast TTE. Successful closure was defined as no LRS at follow-up. Results. In total, 166 patients (mean age 56.7 ± 16.1 years; 62% female) underwent percutaneous ASD closure using the Occlutech Flex I (70%) or Flex II (30%) device (diameter 24 mm; range 10–40 mm) under general anaesthesia and transoesophageal echocardiographic guidance. Long-term follow-up data were available for 144 patients (87%) with a mean follow-up of 5.9 ± 2.6 years, a total of 814 patient-years. During hospitalization, device embolization occurred in three patients (1.8%) with successful extraction in all. During the long-term follow-up, 15 patients (9.8%) suffered new-onset atrial fibrillation and stroke occurred in 2.1%. There was no residual LRS at 12-month follow-up. No device embolization occurred during the long-term follow-up. Conclusion. Percutaneous ASD closure using the Occlutech device appears to be safe at long-term follow-up with a high successful closure rate at one year.

Abstract Background Percutaneous atrial septal defect (ASD) closure carries a not negligible burden of complications, such as the erosion of cardiac structures surrounding the device. Complications related to erosion are rare and often occur during the first 6 months after implantation. Case summary A 40-year-old female patient underwent percutaneous ASD closure in 2006. After 12 years of uneventful follow-up, in March 2018, a device dislodgement causing atrial shunting was incidentally discovered and was attributed to device-induced atrial septal erosion. The patient successfully underwent surgical removal of the device and correction of the interatrial defect. Discussion Our purpose is to underline the importance of staged long-term imaging follow-up, even many years after a successful procedure and to highlight the possible risk factors leading to this worrisome condition. In addition, we sought to underline the possible risks associated with deficient aortic rim and explain pros and cons of different approaches.

The aim of the study was to review our experience with atrial septal defect (ASD) closure with a fenestrated patch in patients with severe pulmonary hypertension. Between July 2004 and February 2009, 16 patients with isolated ASD underwent closure with a fenestrated patch. All patients had a secundum type ASD and severe pulmonary hypertension. Patients ranged in age from 6 to 57 years (mean � SD, 34.9 � 13.5 years). The follow-up period was 9 to 59 months (mean, 34.5 � 13.1 months). The ranges of preoperative systolic and pulmonary arterial pressures were 63 to 119 mm Hg (mean, 83.8 � 13.9 mm Hg) and 37 to 77 mm Hg (mean, 51.1 � 10.1 mm Hg). The ranges of preoperative values for the ratio of the pulmonary flow to the systemic flow and for pulmonary arterial resistance were 1.1 to 2.7 (mean, 1.95 � 0.5) and 3.9 to 16.7 Wood units (mean, 9.8 � 2.9 Wood units), respectively. There was no early or late mortality. Tricuspid annuloplasty was performed in 14 patients (87.5%). The peak tricuspid regurgitation gradient and the ratio of the systolic pulmonary artery pressure to the systemic arterial pressure were decreased in all patients. The New York Heart Association class and the grade of tricuspid regurgitation were improved in 13 patients (81.2%) and 15 patients (93.7%), respectively. ASD closure in patients with severe pulmonary hypertension can be performed safely if we create fenestration. Tricuspid annuloplasty and a Cox maze procedure may improve the clinical result. Close observation and follow-up will be needed to validate the long-term benefits.

Objective Optimal atrial septal defect (ASD) closure should combine off-pump techniques with the effectiveness and versatility of open-heart techniques. We report our experience with off-pump ASD closure using the Universal Cardiac Introducer (UCI) in a porcine model. The goal was to create an ASD over the fossa ovale (FO) and position a patch over the ASD under ultrasound (US) imaging and augmented virtual reality guidance. Methods An US probe (tracked with a magnetic tracking system) was positioned into the esophagus (transesophageal echocardiographic probe) for real-time image-guidance. The right atrium (RA) of six pigs was exposed via a right lateral thoracotomy or medial sternotomy. The UCI was attached to the RA wall. A punching tool was introduced via the UCI, navigated and positioned, under US guidance, to create an ASD into the FO. A patch with its holder and a stapling device were introduced into the RA via the UCI. The patch was positioned on the ASD. Occlusion of the ASD was determined using US and Doppler imaging. Results The FO membrane was excised successfully in all animals. US image-guidance provided excellent visualization. The patch was positioned in all cases with complete occlusion of the ASD. The stapling device proved too bulky, impeding circumferential positioning. Conclusions Using the UCI, ASD closure was safe and feasible. US imaging, combined with virtual and augmented reality provided accurate navigating and positioning. This study also provided valuable information on the future design of anchoring devices for intracardiac procedures.

The Impact

We developed a framework to predict the impact of atrial septal defect (ASD) closure on hemodynamics by incorporating ASD shunt flow into the framework of circulatory equilibrium. The proposed framework accurately predicted hemodynamics after ASD closure. Patient-specific prediction of hemodynamics may be useful for safety management of ASD closure.
