Introduction : Stent implantation is an effective therapy for aortic coarctation (CoA) in adolescents and adults. Aim : To present a unique group of patients with native coarctation of the aorta older than or equal to 46 years treated with bare metal or covered stents. Material and methods : Since 2002 we have performed stent implantations by applying bare metal stents or covered stents using femoral access in 24 patients aged 46 and older. Results : We used the Mullins technique in all cases, implanting different stents: Palmaz, Cheatham-Platinum (CP), covered CP or Andrastents XL/XXL. Twenty-one procedures were elective and 3 were urgent. Eighteen bare metal stents (2 stents in one patient) and 7 covered stents were used. All procedures were effective (CoA gradient reduced < 20 mm Hg), despite 2 migrations of bare metal stents. Mean gradient was reduced from 50.6 ±15.3 to 6.8 ±6.5 mm Hg (p < 0.001) and mean lumen diameter of stenosed aorta increased from 5.5 ±2.5 to 14.9 ±5.2 mm (p < 0.001). One special case is discussed – a 49-year-old man with end staged heart failure and severe CoA, who underwent a rescue procedure with a bare metal stent. One serious complication – stroke of the central nervous system – was observed in a 53-year-old woman during covered stent implantation (symptoms resolved during rehabilitation process). Conclusions : Stent implantation of native coarctation of the aorta is also a safe procedure in the eldest patients and is associated with persistent relief of aortic obstruction.

Introduction : Balloon angioplasty (BAP) and aortic or pulmonary balloon valvuloplasty (BAV, BPV) are well-established treatment options in congenital heart defects. Recently, significant technological progress has been made and new catheters have been implemented in clinical practice. Aim: To analyze the results of BAP, BAV and BPV with the new balloon catheter Valver and its second generation Valver II, which the company Balton (Poland) launched and developed. These catheters have not been clinically evaluated yet. Material and methods: We performed 64 interventions with Valver I and Valver II. With Valver I the following procedures were performed: 17 BPV (including 9 in tetralogy of Fallot – TOF), 10 BAV and 27 BAP in coarctations of the aorta (CoA) – including 9 native and 18 after surgery. With Valver II ten interventions were done – 3 BPV, 2 pulmonary supravalvular BAP (after switch operations), 2 BAP of recoarctations and 3 other BAP. Age of the patients ranged from a few days to 40 years. Results: All procedures were completed successfully, without rupture of any balloon catheters. The pressure gradient drop was statistically significant in all groups: BPV in isolated pulmonary valvular stenosis 28.1 mm Hg (mean), BPV in TOF 18.7 mm Hg, BAV 32.8 mm Hg, BAP in native CoA 15.4 mm Hg and in recoarctations 18.6 mm Hg. In 3 cases during rapid deflation of Valver I, wrinkles of the balloons made it impossible to insert the whole balloon into the vascular sheath (all were removed surgically from the groin). No such complication occured with Valver II. Conclusions : Valver balloon catheters are an effective treatment modality in different valvular and vascular stenoses.

Objectives. Patent ductus arteriosus (PDA) in elderly patients is an uncommon anomaly, and the duct itself is often calcified and fragile; therefore, transcatheter closure is more difficult. The aim is to analyse periprocedural and one-year follow-up results of transcatheter closure of PDA in such patients. Methods and results. Retrospective analysis of 33 elective patients aged ≥55 years (median 63; 56–85; 29 women), in whom PDA was closed percutaneously between 2002 and 2018 in two tertiary centres. All but three patients were symptomatic, with most in NYHA II (n = 14) and III (n = 11) class; pulmonary hypertension (n = 22), arterial hypertension (n = 22), duct calcifications (n = 17), atrial fibrillation (n = 15), significant mitral regurgitation (n = 5), and decompensated renal failure (n = 2) were observed. Different devices were applied depending on PDA morphology; nitinol wire mesh occluders with symmetrical articulating discs have been the most used in recent years (n = 11). Follow-up was conducted at an outpatient clinic (28/33 patients). The procedure was successful in all patients. There was one embolisation, followed by implantation of a larger device. No major complications were noted. A small residual shunt was present in echocardiography in one patient after one year. NYHA class improved in all but two patients (with multiple comorbidities). Conclusions. Transcatheter PDA closure in elderly patients is safe and efficient with a high complete closure rate and few complications. Amplatzer duct occluder type II is an attractive device in such patients.
