ABSTRACT

OBJECTIVE: To evaluate the GORE® Cardioform ASD Occluder (GCO) (WL Gore & Associates, Flagstaff, AZ) device for "complex" atrial septal defects (ASD) closure. BACKGROUND: Transcatheter ASD closure is still challenging in "complex" clinical/anatomic settings. This study evaluated the results of GCO in closure of "complex" ASD in a tertiary referral center. METHODS: Between January 2020 and March 2021, 72 patients with significant ASD were submitted to transcatheter closure with GCO at our Institution. Based on clinical/anatomic characteristics, they were classified as "complex" (n = 36, Group I) or "simple" (n = 36, Group II). We considered as "complex", defects with rim deficiency (< 5 mm) other than antero-superior, relatively large (diameter/patient weight > 1.2 or diameter/patient BSA > 20 mm/m2 ) or within a multifenestrated septum. Procedure results and early outcome were compared between the groups. RESULTS: Absolute and relative ASD size (20 ± 4 vs. 15 ± 3 mm, p < 0.0001; 0.9 ± 0.3 vs. 0.4 ± 0.2 mm/kg, p < 0.0001; 23 ± 7 vs. 12 ± 5 mm/m2 , p < 0.0001), QP/QS (2.0 ± 0.8 vs. 1.4 ± 0.3, p < 0.001), procedure and fluoroscopy times (73 ± 36 vs. 43 ± 21 min, p < 0.0001; 16 ± 9 vs. 9 ± 4 min, p < 0.0001, procedure feasibility (94.4 vs. 100%, p < 0.0001) and overall complication rate (13.9 vs. 0%, p < 0.0001) were significantly different between the groups. Successful closure of "surgical" ASDs was achieved in 92% of cases. Complete closure at last follow-up evaluation did not significantly differ between the groups (97.1 vs. 100%, p = NS), as was wireframe fractures rate (49.1% in the overall population), without clinical, EKG and echocardiographic consequences. CONCLUSIONS: Percutaneous treatment with GCO device is effective and safe in high percentage of "complex" ASDs.

ABSTRACT

A comprehensive description of morbidity and mortality as well as risk factors of interventional cardiac catheterization performed in neonatal age was reported in our paper recently published on the International Journal of Cardiology (IJCA28502; PII: S0167-5273(20)30384-3; DOI: 10.1016/j.ijcard.2020.04.013). Eight Italian high-volume centres of Paediatric Cardiology were involved in this observational, retrospective data collection and analysis. In this dataset, clinical and procedural characteristics of 1423 newborns submitted to 1551 interventional cardiac catheterization procedures were analyzed. Primary outcomes were considered procedure and in-hospital mortality as well as major adverse event and procedural failure rates. Secondary outcomes were considered minor adverse events and need for blood transfusion. Targets of this data analysis were: 1) to evaluate the overall major risk factors of interventional cardiac catheterization; 2) to identify the most hazardous interventional procedures; 3) to assess possible trends of individual procedures as well as their outcome over time; 4) to find possible relationships between the volume activity of any centre and the procedure and follow-up outcome. In particular, this Data in Brief companion paper aims to report the specific statistic highlights of the multivariable analysis (binary logistic regression) used to assess the impact of any potential risk factors on the type of procedure over a short-term follow-up.

ABSTRACT

BACKGROUND: Despite recent technical advances, interventional cardiac catheterization is still challenging in neonatal age and no specific data concerning early outcome are so far published in literature. METHODS: Neonatal trans-catheter cardiac interventions performed in high-volume Italian referral centers were retrospectively analyzed. Primary outcomes were procedural major adverse events, in-hospital mortality and procedural failure. Secondary outcomes were minor adverse events and need for blood transfusion. RESULTS: From January 2000 to December 2017, 1423 newborns (mean weight 3.0 ± 0.6 kg, range 1.0-5.8; median age 2.0 days) underwent interventional cardiac catheterization. Overall, global procedure adverse event rate and in-hospital mortality were 10.2% and 5.2%, respectively. At multi-variable analysis, primary composite outcome was significantly related to low-weight (<2.5 kg) (p < 0.01) and younger age (≤7 days) (p < 0.01) at the procedure, prematurity (p < 0.01), uni-ventricular physiology (p < 0.01), associated genetic syndromes (p < 0.01) and procedure risk category (p < 0.01). No relationship between volume of activity of any single center and procedure outcome was found. Over time, a trend toward an increased number of procedures and their complexity was recorded. Trans-catheter management of cardiac malformations with critical, duct-dependent pulmonary blood flow by arterial duct stenting or right ventricular outflow tract stenting showed the highest increase. CONCLUSIONS: Interventional cardiac catheterization is relatively safe and feasible in neonatal age. Peri-natal age, low weight, uni-ventricular physiology and genetic syndromes still significantly contribute to procedural morbidity and in-hospital mortality of this approach.

ABSTRACT

We describe a case of transposition of the great arteries (TGA) with significant aortopulmonary collateral vessels causing management difficulties before and after an arterial switch operation. Preoperatively, the presence of collaterals exacerbated aortic diastolic runoff and led to myocardial ischemia. Postoperatively, despite uneventful extubation, the infant developed clinical heart failure characterized by pericardial and pleural effusions and feeding difficulties, which promptly resolved with percutaneous embolization of collaterals. Major aortopulmonary collaterals are rarely associated with TGA, but if present they may cause important hemodynamic imbalance in infants with TGA.

ABSTRACT

Late stent thrombosis represents a life-threatening event, usually triggered by inadequate antiplatelet therapy and promoted by multiple risk factors, such as stenting of a chronic total occlusion, overlapping stenting, an abnormal vascular response to the eluted drug, stent malapposition and stent fracture. A 57-year-old man with aspirin hypersensitivity underwent successful percutaneous revascularization of a chronic total occlusion of the left anterior descending artery (LAD). He received two sirolimus-eluting stents overlapping for 2 mm and was discharged on clopidogrel and picotamide. Two years later, 15 days after clopidogrel discontinuation, he experienced an anterior ST-segment elevation myocardial infarction and underwent rescue percutaneous LAD thrombectomy after unsuccessful fibrinolysis. Coronary angiography showed fracture of the distal stent, with a 5 mm gap between the two portions, as well as severe late stent malapposition, confirmed by optical coherence tomography. Despite treatment with clopidogrel and picotamide, in the following days the patient experienced two new episodes of stent thrombosis, treated with thrombectomy and deployment of bioengineered stents. The patient underwent successful oral aspirin desensitization, with a complete in vitro inhibition of platelet function, and was discharged on aspirin, clopidogrel and warfarin, without experiencing other events at 6-month follow-up.
