RESUMO
BACKGROUNDS: We reported the short- and long-term results of our institutional single center registry Interatrial Septum Interventions Study (ISIS) about the impact of different anatomic characteristics and related device selection in patent foramen ovale (PFO) closure. METHODS: Over a 9 year period (September 2003-September 2012) we prospectively enrolled 340 consecutive patients (mean age 44 ± 15. 5 years, 198 females) who had been referred to our center for PFO catheter-based closure. The first 105 patients received a single type of device independently from the anatomy (single device strategy). The remaining 235 patients received a different device based on intracardiac echocardiographic study of interatrial septum anatomy (anatomic strategy). RESULTS: Immediate success rate was 100% in both groups, whereas the rate of immediate complications was 10.4% and 2.5% (P<0.01) in the single strategy group and anatomic strategy group, respectively. During a mean follow-up of 59.3 ± 28.9 months, the occlusion rate was 86.6% and 94%, whereas the incidence of recurrences was 1.8% and 0% in the single device strategy group and anatomic strategy group, respectively. CONCLUSION: The results from ISIS registry showed that anatomy of interatrial septum associated with PFO is quite complex leading to an increased rate of complications and a slightly lower closure rate if treated with a single device strategy.

BACKGROUND: The need for sizing the secundum atrial septal defect (ASD) with the balloon sizing technique is still debated at least in adult patients. We sought to prospectively evaluate the effectiveness of intracardiac echocardiography (ICE)-aided sizing technique for transcatheter closure of secundum ASD, without using a balloon sizing. METHODS: In a prospective 5-year registry, we enrolled 81 patients (mean age 48 ± 13.7 years, 54 females) who had been referred to three different centers for atheter-based closure of secundum ASD. Eligible patients underwent ICE study and closure attempt. In a preliminary group of 21 patients, sizing balloon was performed under ICE guidance to assess the value of rim thickness necessary for device anchorage. In the remaining 60 patients, the retrieved value of the rim thickness was measured on ICE and used as key points to measure the defect and select the device. RESULTS: In the preliminary group of patients, the value of thickness at point of initial deflection by the balloon was 1.23 ± 0.1 mm. ASD diameter in the study group was measured at the point of rim with at least 1.2 mm and the mean ASD diameter was 26.2 ± 10.1 mm. Rates of procedural success, predischarge occlusion, and major complications rate were 100%, 93.3%, and 0%, respectively. On mean follow-up of 5.4 ± 1.8 years, the occlusion rate was 98.7% with no long-term complications. CONCLUSIONS: Our novel ICE-sizing technique appears to be safe and effective in adult patients, thus eventually minimizing overestimation, costs, and potential complications of balloon sizing.

Congenital coronary anomalies remain a debated issue. On the basis of a critical review of the literature and our historical series, we propose a simple clinical profile scoring system for congenital coronary anomalies. A review of literature over the past 30 years was performed, searching for a relationship between the worst coronary anomaly presentation and manifestations and the anatomical and functional features. A risk scoring system was created based on these features, and retrospectively applied to our historical series of 140 consecutive patients (52 females; mean age, 60.1±19.3 years; mean follow-up, 60±23 months). Origin from the pulmonary artery, intramural course, intramyocardial course, coronary fistula with a significant pulmonary-to-systemic flow ratio, superimposed coronary artery disease, and associated congenital heart disease were associated with the worst clinical presentation. The risk scoring system gave 2 points to anatomical features and 1 point to the association with clinical and functional characteristics: 3 risk classes were identified: >3, 2-3, and <2 points. The system showed good correlation with presentation and manifestations on follow-up. Although not exhaustive, the proposed scoring system may simplify the clinical evaluation of patients with such abnormalities, being a model for decision making.
