RESUMO
BACKGROUND: The morphology of a patent foramen ovale (PFO) with a high-risk for cryptogenic ischemic stroke (CS) is an important factor in the selection of patients for transcatheter closure, but the morphological features of PFO in older patients with a history of CS are less known because the most data are obtained from younger patients. METHODS AND RESULTS: The study included 169 patients who had a history of CS and PFO. The prevalence of high-risk morphologies of PFO assessed by transesophageal echocardiography was compared between patients aged ≥60 years and patients aged <60 years. We also assessed the presence of septal malalignment of PFO on the aortic wall. The probability of CS due to PFO was evaluated using the PFO-Associated Stroke Causal Likelihood classification system. Patients aged ≥60 years had a significantly higher prevalence of atrial septal aneurysm than patients aged <60 years. The prevalence of large right-to-left shunt, long-tunnel of PFO, or Eustachian valve or Chiari's network was similar between patients aged ≥60 years and <60 years. Septal malalignment was observed more frequently in patients aged ≥60 years than in those <60 years old. Nearly 90% of patients aged ≥60 years were classified as 'possible' in the PFO-Associated Stroke Causal Likelihood classification system. CONCLUSIONS: High-risk morphologies of PFO are common in older patients with a history of CS, as well as in younger patients.

BACKGROUND: The AmplatzerTM PFO Occluder was approved for marketing in Japan in May 2019, and the Amplatzer PFO Occluder Japan Post-marketing Surveillance (PFO Japan PMS) study was initiated in December 2019. This analysis presents 30-day clinical outcomes for PFO Japan PMS study patients. METHODS AND RESULTS: PFO Japan PMS is a prospective single-arm non-randomized multicenter clinical study. Eligible patients were indicated for patent foramen ovale (PFO) closure and underwent an implant attempt with the AmplatzerTM PFO Occluder. Technical success was defined as successful delivery and release of the occluder; procedural success was defined as technical success with no serious adverse events (SAEs) within 1 day of the procedure. The primary safety endpoint includes predefined device- and/or procedure-related SAEs through 30 days after the procedure. From December 2019 to July 2021, 500 patients were enrolled across 53 Japanese sites. The mean (±SD) patient age was 52.7±15.4 years, and 29.8% of patients were aged >60 years. Technical and procedural success rates were both high (99.8% and 98.8%, respectively). Further, there was only one primary safety endpoint event (0.2%): an episode of asymptomatic paroxysmal atrial fibrillation that occurred 26 days after the procedure. CONCLUSIONS: In this real-world Japanese study with almost one-third of patients aged >60 years, PFO closure with the AmplatzerTM PFO Occluder was performed successfully and safely, with a low incidence of procedure-related atrial arrhythmias.

BACKGROUND: Atrial septal defect (ASD) closure can cause acute pulmonary edema. Before transcatheter closure is performed, temporary balloon occlusion test (BOT) is recommended in patients with left ventricular dysfunction to predict the risk of pulmonary edema. However, the accuracy of BOT has not been verified. This study aimed to compare hemodynamic differences between BOT and transcatheter closure. METHODS: A total of 42 patients with a single ASD over age 18 years who underwent BOT before transcatheter ASD closure between October 2010 and May 2020 were analyzed. Pulmonary capillary wedge pressure (PCWP) was measured using a Swan-Ganz catheter placed in the pulmonary artery at baseline, after 10 min of BOT, and after transcatheter closure. Amplatzer septal occluder was used for all transcatheter closures. RESULTS: Mean patient age was 64 ± 18 years (range, 18-78). Mean ASD diameter and pulmonary to systemic flow ratio were 18 ± 5 and 2.8 ± 1.0 mm, respectively. Mean PCWP at baseline, during BOT, and after transcatheter closure was 8.9 ± 2.9, 13.5 ± 4.2, and 9.5 ± 2.6 mmHg, respectively. The difference between BOT and after transcatheter closure values was significant (p < 0.001). During BOT, PCWP increased ≥18 mmHg in 7 patients, whereas after ASD closure, PCWP was <18 mmHg in all 7 and none developed acute pulmonary edema. CONCLUSION: Temporary balloon occlusion of an ASD and transcatheter ASD closure result in different hemodynamic change. BOT overestimates increase of PCWP after transcatheter ASD closure and requires careful interpretation. Well-designed, larger studies in higher-risk patients are warranted to verify the clinical implications of BOT in more detail.

BACKGROUND: Transcatheter mitral valve repair with the MitraClip system has been established in selected high-risk patients. The MitraClip procedure results in a relatively large iatrogenic atrial septal defect (iASD). This study aimed to investigate the prevalence and clinical course of iASD requiring transcatheter closure following the MitraClip procedure.MethodsâandâResults: This study was conducted at all 59 institutions that perform transcatheter mitral valve repair with the MitraClip system in Japan. The data of patients on whom transcatheter iASD closure was performed were collected. Of the 2,722 patients who underwent the MitraClip procedure, 30 (1%) required transcatheter iASD closure. The maximum iASD size was 9±4 mm (range, 3-18 mm). The common clinical course of transcatheter iASD closure was hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt. Of the 30 patients, 22 (73%) required transcatheter closure within 24 h following the MitraClip procedure, including 12 with hypoxemia and 5 with right-sided heart failure complicated with cardiogenic shock. Of the 5 patients, 2 required mechanical circulatory support devices. Twenty-one patients immediately underwent transcatheter iASD closure, and hemodynamic deteriorations were resolved; however, 1 patient died without having undergone transcatheter closure. CONCLUSIONS: Transcatheter iASD closure was required in 1% of patients who underwent the MitraClip procedure. Many of these patients immediately underwent transcatheter iASD closure because of hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt.

Patent foramen ovale (PFO) is implicated in the pathogenesis of a number of medical conditions but to date only one official position paper related to left circulation thromboembolism has been published. This interdisciplinary paper, prepared with the involvement of eight European scientific societies, reviews the available evidence and proposes a rationale for decision making for other PFO-related clinical conditions. In order to guarantee a strict evidence-based process, we used a modified grading of recommendations, assessment, development, and evaluation (GRADE) methodology. A critical qualitative and quantitative evaluation of diagnostic and therapeutic procedures was performed, including assessment of the risk/benefit ratio. The level of evidence and the strength of the position statements were weighed and graded according to predefined scales. Despite being based on limited and observational or low-certainty randomised data, a number of position statements were made to frame PFO management in different clinical settings, along with suggestions for new research avenues. This interdisciplinary position paper, recognising the low or very low certainty of existing evidence, provides the first approach to several PFO-related clinical scenarios beyond left circulation thromboembolism and strongly stresses the need for fresh high-quality evidence on these topics.

OBJECTIVES: This study aimed to assess the feasibility of transcatheter atrial septal defect (ASD) closure in patients with absent aortic rim. BACKGROUND: The indication of transcatheter closure for ASD with absent aortic rim is controversial. METHODS: We enrolled 547 patients with ASD who were scheduled for transcatheter closure. Morphologies of aortic rim were evaluated using transesophageal echocardiography (TEE). RESULTS: Aortic rim of <5 mm was observed in 396 (72%) patients; 128 (23%) had absent aortic rim of 0 mm, and 268 (49%) had deficient aortic rim of >0 to <5 mm. Patients with absent aortic rim frequently had aortic rim absence at an angle of 0° on TEE and septal malalignment. Of the 128 patients with absent aortic rim, 126 (98%) successfully underwent transcatheter closure, while 2 (2%) failed transcatheter closure due to a large defect with severe septal malalignment. The success rate of transcatheter closure was similar between patients with absent aortic rim and those with deficient aortic rim (98% vs. 99%, p = .45). After the procedure, no patients had erosion or device embolization during a median follow-up of 24 months. CONCLUSIONS: Transcatheter closure was successfully performed without adverse events in patients with absent aortic rim, as well as in those with deficient aortic rim. Our findings can be valuable to determine the indication of transcatheter closure in patients with ASD.

OBJECTIVES: This study aimed to determine morphological characteristics of deficient posterior-inferior rim for transcatheter atrial septal defect (ASD) closure success. BACKGROUND: The feasibility of transcatheter closure of ASD with deficient posterior-inferior rim remains unclear. METHODS: Of 869 patients with ASD who were scheduled transcatheter closure, 121 with posterior-inferior rim of <5 mm were included. Posterior-inferior rim morphologies were evaluated by transesophageal echocardiography. RESULTS: One hundred six patients successfully underwent transcatheter closure, while 15 patients failed. These 15 patients had complete deficient posterior-inferior rim of 0 mm and/or a large defect of ≥38 mm. Multivariate logistic regression analysis showed that transcatheter closure failure was independently related to complete deficient posterior-inferior rim and a large defect of ≥38 mm. Incomplete deficient posterior-inferior rim of >0 to <5 mm was observed in 84 patients. All these patients successfully underwent transcatheter closure, except two patients with a large defect of ≥38 mm. Complete deficient posterior-inferior rim was observed in 37 patients. The frequency of complete deficient posterior-inferior rim was higher in patients who failed transcatheter closure (87% vs. 23%, p < .01), but transcatheter closure was performed successfully if the range of complete deficient rim was ≤30°. After the procedure, no adverse events occurred during a median follow-up of 24 months. CONCLUSIONS: Most patients with deficient posterior-inferior rim successfully underwent transcatheter closure. Transcatheter closure could be performed even in patients with complete deficient posterior-inferior rim if the range was partial. Our findings can help to identify candidates for transcatheter closure.

Few studies have reported the efficacy of Occlutech Figulla Flex II (FFII) device compared with Amplatzer Septal Occluder (ASO) device. The aim of this study was to examine the efficacy and safety of FFII compared with ASO for transcatheter atrial septal defect (ASD) closure. We retrospectively evaluated 190 patients using FFII and 190 patients using ASO who underwent transcatheter ASD closure. ASD characteristics were evaluated by transesophageal echocardiography. The prevalence of procedural complications, including erosion, device embolization, stroke, and new-onset atrial arrhythmia, and the presence of a residual shunt were evaluated between the two groups during 12-month follow-up. FFII was used more frequently than ASO in patients with a deficient aortic rim or septal malalignment (P = 0.02, P < 0.01, respectively). The procedural complications of erosion, device embolization, and stroke did not occur in any patients. New-onset atrial arrhythmia occurred in 3 patients of the FFII group and 4 patients of the ASO group, and the difference between the two groups was not significant (P = 0.70). A large residual shunt (≥ 3 mm) was observed in 6 patients of the FFII group and 5 patients of the ASO group, and the difference between the two groups was not significant (P = 0.76). FFII was used frequently in patients with high-risk ASD morphology; however, there was no difference in the prevalence of procedural complications or efficacy between patients using FFII and those using ASO.

BACKGROUND: Because transcatheter closure of patent foramen ovale (PFO) has become effective for preventing cryptogenic stroke (CS), it is necessary to determine high-risk PFO associated with CS. This study aimed to clarify the importance of direct right-to-left (RL) shunt through the PFO for identifying high-risk PFO. METHODS: We analyzed 137 patients with and without CS who were confirmed to have PFO. The timing of RL shunt through the PFO was evaluated by cardiac cycles after right atrium (RA) opacification on saline contrast transesophageal echocardiography. Direct RL shunt was defined as microbubbles crossing the PFO before and at the same time of RA opacification. RESULTS: Cardiac cycles of microbubbles crossing the PFO were shorter in patients with CS than in those without CS (2.0 ± 2.2 vs .5 ± 1.1, p < 0.01). Direct RL shunt was more frequently observed in patients with CS than in those without CS (77% vs 29%, p < 0.01), with a sensitivity of 79% and a specificity of 71% for the association with CS. Multivariate analysis revealed that direct RL shunt was related to atrial septal aneurysm and low-angle PFO. Regarding functional features of PFO, the detection rate of CS was 50% for large RL shunt alone, and was increased to 83% when direct RL shunt was added. CONCLUSION: Direct RL shunt was associated with CS and had the incremental value in detecting PFO associated with CS for large RL shunt. The timing of RL shunt can be valuable for identifying high-risk PFO.

OBJECTIVES: Patent foramen ovale is a hemodynamically insignificant interatrial communication that may cause ischemic stroke. Percutaneous patent foramen ovale closure reduces the risk for recurrent ischemic stroke in patients with a history of cryptogenic ischemic stroke. This study evaluated the cost-effectiveness of patent foramen ovale closure against medical therapy in patients after their first cryptogenic ischemic stroke in Japan. MATERIALS AND METHODS: The cost-effectiveness of patent foramen ovale closure compared with medical therapy was evaluated using the Markov model. The target patients started with patent foramen ovale closure or medical therapy for preventing secondary ischemic stroke under a stable state. Quality-adjusted life year was used as the outcome of effectiveness, and the analysis was conducted with a discount rate of 2% applied to both cost and effectiveness. The results of a multicenter open-label randomized controlled trial (RESPECT trial) evaluating patent foramen ovale closure using the Amplatzer™ PFO Occluder were used as clinical evidence. Cost-effectiveness was evaluated using the incremental cost-effectiveness ratio. It was evaluated as cost-effective if it was lower than 5 million JPY/ quality-adjusted life year. RESULTS: Patent foramen ovale closure was dominant over medical therapy by 2.53 quality-adjusted life years and an estimated cost reduction of 2,353,926 JPY. The probability of patent foramen ovale closure being dominant was 82.9%. CONCLUSIONS: Patent foramen ovale closure was dominant over medical therapy for preventing secondary ischemic stroke in patients with cryptogenic ischemic stroke.

BACKGROUND: Septal malalignment is related to erosion and device embolization in transcatheter closure of atrial septal defect (ASD), but limited information is available. OBJECTIVES: This study aimed to assess clinical significance of septal malalignment and to determine appropriate evaluation of ASD diameter, including the selection of device size. METHODS: Four hundred and seventeen patients with ASD who underwent transcatheter closure were enrolled. Septal malalignment was defined as separation between the septum primum and the septum secundum on transesophageal echocardiography. RESULTS: One hundred and eighty-four patients had septal malalignment. The frequency of septal malalignment increased with age reaching around 50% in adult patients. Septal malalignment was related to aortic rim deficiency. The distance of separation between the septum primum and the septum secundum was 5 ± 2 mm (range, 1-11 mm). In patients with septal malalignment, the ASD diameter measured at the septum primum was 19 ± 6 mm, while the ASD diameter measured at the septum secundum was 16 ± 6 mm. There was a difference of 4 ± 2 mm (range, 0-8 mm) between the ASD diameter measured at the septum primum and that measured at the septum secundum. For transcatheter closure, the Amplatzer Septal Occluder device size 2-3 mm larger and the Occlutech Figulla Flex II device size 4-7 mm larger than the ASD diameter measured at the septum primum were frequently used. During the study period, erosion or device embolization did not occur in all of the patients. CONCLUSIONS: Septal malalignment is highly prevalent in adult patients with aortic rim deficiency. The measurement of ASD diameter at the septum primum can be valuable for the selection of device size in patients with septal malalignment.

OBJECTIVE: The aim of this study was to examine the relationship between right ventricular (RV) volume and exercise capacity in adult patients with atrial septal defect (ASD) and to determine the degree of RV dilatation for transcatheter ASD closure. BACKGROUND: RV dilatation is an indication of transcatheter ASD closure; however, few studies have reported the clinical significance of RV dilatation. METHODS: We enrolled 82 consecutive patients (mean age, 49 ± 18 years; female, 68%) who underwent cardiac magnetic resonance imaging and symptom-limited cardiopulmonary exercise test before ASD closure. The relationship between RV volume and peak oxygen uptake (VO2) was evaluated. RESULTS: The mean RV end-diastolic volume index was 108 ± 27 ml/m2 (range, 46 to 180 ml/m2). The mean peak VO2 was 24 ± 7 ml/min/kg (range, 14 to 48 ml/min/kg), and the mean predicted peak VO2 was 90 ± 23%. There were significant negative relationships of RV end-diastolic volume index with peak VO2 (r = -0.28, p < 0.01) and predicted peak VO2 (r = -0.29, p < 0.01). The cutoff value of RV end-diastolic volume index <80% of predicted peak VO2 was 120 ml/m2, with the sensitivity of 49% and the specificity of 89%. CONCLUSIONS: There was a relationship between RV dilatation and exercise capacity in adult patients with ASD. RV end-diastolic volume index ≥120 ml/m2 was related to the reduction in peak VO2. This criterion of RV dilatation may be valuable for the indication of transcatheter ASD closure.

AIMS: There is no valid treatment strategy for addressing paroxysmal atrial fibrillation (AF) in patients with unclosed atrial septal defect (ASD). We aimed to assess the efficacy of catheter ablation (CA) compared with transcatheter ASD closure alone for treating pre-existing paroxysmal AF in patients with ASD. METHODS AND RESULTS: Among 908 patients who underwent transcatheter ASD closure, we evaluated 50 consecutive patients (63 ± 12 years) with paroxysmal AF. We compared the AF outcomes of these patients after transcatheter ASD closure between those with and without CA prior to ASD closure. Thirty (60%) patients underwent CA. During the follow-up period after ASD closure (mean: 49 ± 23 months), recurrence of AF was observed in 6/30 (20%) patients with upfront CA and 12/20 (60%) patients with ASD closure alone. Kaplan-Meier analysis showed that the AF-free survival rate was significantly higher for patients with CA than for those with ASD closure alone (79% vs. 37% at 5 years, P = 0.002). Upfront CA and previous heart failure hospitalization were associated with recurrence of AF after ASD closure [hazard ratio (HR) 0.18, 95% confidence interval (CI) 0.06-0.53; P = 0.002 and HR 4.64, 95% CI 1.60-13.49; P = 0.005, respectively]. CONCLUSION: In ASD patient with paroxysmal AF, transcatheter ASD closure alone demonstrated high AF recurrence rate after ASD closure. On the other hand, upfront CA prior to ASD closure substantially suppressed AF recurrence over the long term. A combination of CA and transcatheter ASD closure may be a feasible treatment strategy for paroxysmal AF in patients with ASD.

The follow-up of patients with adult congenital heart disease (ACHD) at a specialized medical unit is necessary for the patients' appropriate medical care. However, limited information is available about cardiovascular events among ACHD patients. Here we investigated the type and frequency of cardiovascular events in ACHD patients in relation to disease complexity. We retrospectively analyzed the cases of 535 patients (median age 35 years) referred to our ACHD center between 2014 and 2017. We divided the patients into 3 groups based on their disease complexity. To evaluate the relationship between disease complexity and cardiovascular events, we performed univariate and multivariate survival analyses. The Simple, moderate, and complex disease groups accounted for 62%, 19%, and 19% of the patients, respectively. Apart from events related to atrial septal defect (ASD) trans-catheter treatment, the frequency of cardiovascular events was dependent on the disease complexity (event-free survival rates at 3 years were 85%, 65%, and 58%, respectively). The hazard ratios were 4.0 and 5.1 in the moderate and complex groups, respectively. With the exception of scheduled transcatheter intervention, cardiovascular events were strongly related to the disease complexity of original heart disease. However, cardiovascular events were not rare even in the simple ACHD group.

BACKGROUND: Device embolization is the most frequent procedural complication during transcatheter closure of congenital cardiac defects. Retrieval of an embolized device may often be complicated by failure to introduce the right atrial (RA) disk hub into the sheath or difficulty in securely grasping the hub pin of RA disk. We aimed to evaluate the efficiency and success rate of device retrieval using a novel double snare technique. METHODS: We reviewed retrieval procedures of embolized atrial septal defect (ASD) or left atrial appendage (LAA) occluder using double snare technique reported from five tertiary referral centers in Korea, Japan, and Uzbekistan. A total of 16 retrieval procedures in 15 patients were reported, including 14 patients who were planned for ASD device closure while 1 patient was planned for LA appendage occlusion. RESULTS: Retrieved devices included 15 ASD occluders from six different manufacturers and one Amplantzer cardiac plug. Success rate of retrieval procedure was 100% using the double snare technique. There were no complications related to device retrieval. Most (15/16, 93.8%) of these devices could be retrieved through their original delivery sheaths. In six patients for whom retrieval was unsuccessful with conventional single snare technique and switched to double snare technique, the retrieval time was shortened significantly (P = 0.004*) by using the double snare technique. CONCLUSIONS: The double snare technique enables effective retrieval of various embolized devices. It abolishes the need of changing the sheath to a larger one in most patients.

BACKGROUND: Fontan-associated liver disease (FALD) is an important late complication involving liver dysfunction, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC), in patients undergoing the Fontan procedure. However, the prevalence, clinical manifestation, and methods of diagnosis of FALD are still not well established.MethodsâandâResults:This study comprised 2 nationwide surveys in Japan. First, the prevalence of LC and/or HCC in patients undergoing the Fontan procedure was determined. Second, clinical manifestations in patients with LC and/or HCC were analyzed, along with data from blood tests, echocardiography, and right heart catheterization. In the 1st survey, of the 2,700 patients who underwent the Fontan procedure, 31 were diagnosed with LC and/or HCC (1.15%), and 5 died due to liver diseases (mortality: 0.19%). In the 2nd survey, data were collected from 17 patients (12 with LC, 2 with HCC, and 3 with LC+HCC. Of these 17 patients, 5 died (mortality: 29.4%). The mean age at diagnosis of LC and HCC was 23 and 31 years, respectively. Computed tomography followed by ultrasound was most frequently used for diagnosis. Blood tests revealed low platelet counts, increased hemoglobin, aspartate aminotransferase, γ-guanosine triphosphate, and total bilirubin levels, and an elevated international normalized ratio of prothrombin time. CONCLUSIONS: LC and/or HCC in patients undergoing the Fontan procedure were not rare late complications and were associated with high mortality rates.

OBJECTIVE: This study evaluated the effect of echocardiographic left ventricular (LV) diastolic dysfunction on acute congestive heart failure after transcatheter atrial septal defect (ASD) closure in elderly patients. BACKGROUND: Although there is concern that LV diastolic dysfunction develops acute congestive heart failure after ASD closure, limited information is available regarding the influence, especially in elderly patients with severe LV diastolic dysfunction. METHODS: Two hundred consecutive patients older than 60 years were divided into 3 groups according to echocardiographic LV diastolic dysfunction: severe (early diastolic mitral annular velocity [e'] <5.0 cm/s), mild (5.0≤ e' <8.0 cm/s), and normal (e' ≥ 8.0 cm/s). Changes in plasma B-type natriuretic peptide (BNP) levels were evaluated. RESULTS: No patients with severe LV diastolic dysfunction developed acute congestive heart failure immediately after the procedure. BNP levels unchanged after the procedure in patients with severe LV diastolic dysfunction (126 ± 181 to 131 ± 148 pg/ml, P = 0.885), and this increase in BNP levels was not different from that between the diagnosis of ASD and the procedure. The change in BNP levels in patients with severe LV diastolic dysfunction, who were frequently treated with diuretics before the procedure, was equivalent to that in patients with mild LV diastolic dysfunction and normal LV diastolic function (5 ± 119 vs. 16 ± 101 vs. 9 ± 131 pg/ml, P = 0.724). CONCLUSIONS: Our findings suggest that transcatheter ASD closure under volume management is safe and valuable in elderly patients with echocardiographic severe LV diastolic dysfunction.
