The use of a nonfluoroscopic system for catheter navigation significantly reduced fluoroscopy exposure and total procedure duration of RCA of common SVT substrates in children.
Most patients coming to surgery presented in childhood and were significantly symptomatic. More than half underwent valve replacement or repair, but a considerable proportion had severe disease necessitating 1(1/2) ventricle repair or palliative procedures. Operative mortality did not differ significantly among repair, replacement, and 1(1/2) ventricle repair but was associated with palliative procedures for severe disease early in life, young age being the only independent predictor of operative death.
DTI evaluation of tricuspid annular motion during dobutamine infusion in repaired TOF correlates with dP/dt and RV stroke volume and may help in assessing RV function and reserve.
Aims The aim of this study was to evaluate the effect of microsomal triglyceride transfer protein inhibitor (lomitapide) in patients with homozygous familial hypercholesterolaemia. Methods and results In 12 homozygous familial hypercholesterolaemia patients treated with lipid-lowering drugs ± biweekly lipoprotein apheresis sessions (nine patients), daily lomitapide was added. The lipid profile (total cholesterol, low-density lipoprotein cholesterol, triglycerides, high-density lipoprotein cholesterol) before and after lomitapide treatment was evaluated. The follow-up period with lomitapide treatment was 3–24 months (13.8 ± 7.9). The median baseline low-density lipoprotein cholesterol level was 900 mg/dl (348–1070), after lipid-lowering drugs therapy was 383.5 mg/dl (214–866) and after lipid-lowering drugs + time-averaged level was 288 mg/dl (183.7–716.6). The addition of lomitapide lowered low-density lipoprotein cholesterol levels further by 56.8% compared to lipid-lowering drugs alone (mean reduction 262, 95% confidence interval (105.5–418.7), p = 0.005) and by 54% (mean reduction 182.9, 95% confidence interval (−342 – −23), p = 0.031) comparing to lipid-lowering drugs + lipoprotein apheresis (time-averaged level). The time-averaged level of low-density lipoprotein cholesterol in lipid-lowering drugs + lipoprotein apheresis patients compared with lipid-lowering drugs + lomitapide was 54% in favour of lomitapide ( p = 0.031). Conclusions Treatment with lomitapide in homozygous familial hypercholesterolaemia patients has a beneficial effect with a constant decrease of low-density lipoprotein cholesterol by 57% compared with classical lipid-lowering therapy and by 54% compared with classical lipid-lowering therapy and time-averaged level of low-density lipoprotein cholesterol.
This case reports on an 8-year-old boy with homozygous familial hypercholesterolemia with large tuberous xanthomas over his hands, elbows, buttocks, knees, and feet. Lomitapide 40 mg daily (steadily increased) was added to his classical lipid-lowering therapy. A 50% reduction in the thickness, hardness, size, and color intensity of xanthomas was reported after 2 years of treatment. (

We present our experience with the Cera (CO) and the CeraFlex occluder (CFO) in transcatheter closure of interatrial communications (IAC). Between 2013 and 2016, 201 patients (75 males, 16 with patent foramen ovale), aged 27 ± 19 (5-75) years, underwent percutaneous closure of IAC using CO or CFO in our institution. After transoesophageal imaging, the procedure was aborted in 7 young paediatric (6-13 years old) patients (3 multiple holes, 3 too small septum, 1 leak with 38 mm occlusion balloon). The occluder was removed prior to release in 11 patients (5.7%), while occlusion was successful in 183 patients (94.3%) with 44 CO, 136 CFO, and 3 Cera multifenestrated occluders. There were no deaths, embolizations, or major complications. Small residual shunts were demonstrated in 8 patients immediately after implantation, 4 (8.5%) with CO and 4 (2.9%) with CFO, all disappearing after 3 months. Over 1.8 ± 1.7 year follow-up, all patients improved with 2 asymptomatic, transient pericardial effusions and 5 adults with transient supraventricular arrhythmias, treated medically for 6 months. IAC closure with CO and CFO proved safe with favourable success rates and few, nonserious complications. The CFO flexible rotation feature helped in conforming to various septal anatomies, minimising manoeuvres and possibly post-occlusion leaks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
