“…Closure rates increased to 93.3 and 94.6% at discharge in AVSDO and SVSDO groups, respectively, and to 97.8% of all patients at the 12-month follow-up examination. This is in agreement with previously reported studies [10,[16][17][18].…”

“…The more common occurrence of RBBB was probably due to the fact that the right bundle branch is spindly and easily damaged. Third-degree AVB after transcatheter closure of PMVSD is the most serious complication with the occurrence rate ranging from 1.1 to 5.7% reported in the literature [9,10,17,18,21,22]. The occurrence rate of third-degree AVB after transcatheter closure of PMVSD is not higher than that of surgical closure of VSD (1-5%) [23][24][25][26].…”

“…Previous success rates ranged between 89 and 100% [9,10,[13][14][15][16][17]. Procedural failures reported in the literature were mainly due to HBs, device-related aortic or tricuspid regurgitation, significant residual shunts, device embolization, inability to securely position the device, and failure to position the delivery sheath to the left ventricle apex [10,[17][18][19][20]. In our study, complete PMVSD closure was obtained in 88.3% of patients in the AVSDO group and in 87.7% of patients in the SVSDO group immediately following the procedure.…”

“…The coils were used primarily in the small-to-moderate-sized veins, while PDA and ASD occluders were mainly used in moderate-to-large-sized veins. Details regarding these devices and their specific delivery systems have been reported elsewhere [15,16,17]. Briefly, the diameter of the Amplatzer occluder was 3- to 4-mm larger than that of the azygos/hemiazygos vein at its narrowest point, with the mean diameter being 7 ± 3 mm (range 4-12).…”

Objectives: To elucidate the feasibility and treatment effects of transcatheter occlusion of the azygos/hemiazygos vein in patients with progressive cyanosis after performing the bidirectional Glenn procedure. Methods: From January 2007 to May 2011, transcatheter closure was performed on 9 patients (7 males and 2 females) aged 5-15 years (median 9 years). Results: A total of 7 azygos veins and 3 hemiazygos veins were occluded successfully. Coils were employed in 4 of the procedures, patent ductus arteriosus (PDA) occluders in 3, atrial septal defect occluders in 2 and a PDA occluder together with coils in 1 procedure. Immediate complete occlusions were achieved in 9 (81.8%) procedures and trivial residual shunt in 2 (18.2%). The femoral artery oxygen saturation (SaO₂) rose from 81 [interquartile range (IQR) 75-86%] to 88% (IQR 84-91%). Conclusions: Patients with superior vena cava azygos vein collateral channels can be treated successfully by transcatheter occlusion with multiple devices. The device for embolization depends on the extent of the severity of the shunt, the size of the lumen of the azygos vein/hemiazygos vein and the candidate location for occlusion.

“…In addition to AGA Medical, many other companies have now used a range of different designs for ASD, PFO, and PDA closure devices. Nearly all of these devices use nitinol's unique shape memory properties (13)(14)(15)(16)(17)(18). Of note, a nitinol coil manufactured by pfm Medical (Cologne, Germany) is now being used for closure of both PDAs and smaller VSDs (19).…”

"Smart Materials" are materials that change their shape, color, or size in response to an externally applied stimulus. While smart materials have already made a tremendous impact on our lives through their applications in liquid crystal displays, headphones, fuel injection systems, flexible cell phone antennas, and many other commercial products, they also have the potential to help many pediatric patients. This review focuses on with the present and potential applications of shape memory alloys, piezoelectric materials, and the relatively newer class of materials called magnetostrictive and ferromagnetic shape memory alloys in the design of pediatric cardiovascular devices. (Pediatr Res 63: 552-558, 2008) "S mart Materials" are materials that change their shape, color, or size in response to an externally applied stimulus. Examples of "external stimuli" include changes in temperature, application of an electric or magnetic field, and changes in moisture or pH. Thus, whereas other materials play passive structural roles in devices, smart materials can actually be manipulated in situ.During the last few decades smart materials have had a tremendous impact on a variety of fields. For example, chromogenic materials are the basis of all liquid crystal displays and photochromes allow eyeglasses to change to sunglasses in the presence of sun light. The basis of lighter igniter switches, headphones, and recent fuel injection systems is piezoelectrics whereas the flexible cell phone antennas and eyeglasses are shape memory smart materials. Many more commercial applications for smart materials are already available and new ones are being studied by a wide range of organizations.This review focuses on with the potential applications of shape memory alloys, piezoelectric materials, and the relatively newer class of materials called magnetostrictive and ferromagnetic shape memory alloys (FSMA) in the design of pediatric cardiovascular devices. Whereas shape memory alloys like nitinol (a nickel-titanium alloy) change shape in response to a change in temperature, magnetostrictive or ferromagnetic materials change their shape in response to a magnetic field. NiMnGa (nickel-manganese-gallium) and Terfenol-D represent the best known examples of FSMA and magnetostrictive materials respectively. The more mature class of piezoelectric materials, e.g., BaTiO 3 and lead zirconate titanate (Pb(ZrTi)O 3 )-commonly called PZT, change shape with an electrical field; or, conversely, generate an electrical signal in response to a forced change in shape. All of these materials can be used as either an actuator or a sensor.Smart materials have begun to have a significant impact in the field of medicine. Although a number of applications already exist, it is only a matter of time before many more pediatric applications will emerge for these smart materials. SHAPE MEMORY ALLOYSNitinol introduction. NiTi or nitinol is a nickel-titanium shape memory alloy. Nitinol is a pneumonic for NickelTitanium, developed by the Naval Ordinance Labo...
