EDITORIAL
Dhaval R Parekh, Zvonimir Krajcer
Children with branch pulmonary artery stenosis represent a challenging cohort for stenting Premounted stent implantation provides immediate obstruction relief and hemodynamic improvement in infants Planned stent intervention is required to account for somatic growth and next stage palliation in children Continued slenderization of adult coronary and peripheral interventions, stent technology, and delivery systems may allow for more durable solutions in light of patient size.

The authors describe a technique of treating patients with aortic arch aneurysm using surgeon-modified fenestrated stent graft (SMFSG). The technique is demonstrated in a 80-year-old patient whose aneurysm was successfully excluded with a SMFSG using Cook Alpha thoracic stent graft. The device was deployed, removed from its delivery system, and a fenestration created before being mounted back on the delivery system and constrained. It was transitioned through a series of sheaths before being introduced into its original sheath...

OBJECTIVES: Our goal was to assess the viability of an alternative anchoring design for a transcatheter aortic valve based on a form-fitting principle with a self-expanding nitinol frame to reduce issues related to excess radial force. METHODS: A 26-mm outer diameter prototype of a self-expanding nitinol frame was developed to reduce the amount of necessary radial force by utilizing additional anchoring via protruding arms in each aortic sinus, thus allowing for a form-fitting principle as well as the coaxial self-alignment of the valve inside the native anatomy...

INTRODUCTION: Although Fenestrated TEVAR (F-TEVAR) has been considered to be a more physiologic approach to treat proximal descending aortic pathology, its application is still limited due to availability, cost and technical difficulties. We introduce a new design of fenestrated stent graft with a new delivery system and successfully performed first in human implantation in two patients, one with an aortic aneurysm and one with an acute aortic dissection. MATERIALS AND METHODS: The design of these two wires fenestrated stent graft include creation of an additional lumen at the side of the olive tip during manufacture, from which an additional wire can be introduced for a side branch passing into the fenestration, running inside the stent graft and exit the delivery sheath through additional hub...

BACKGROUND: Calcified coronary lesions often cause suboptimal stent expansion, which is one of the greatest predictors of adverse outcomes such as stent thrombosis and restenosis. Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical, Inc) is a recently approved technique used in the treatment of heavily calcified coronary lesions. We present our early real-world experience with the S-IVL device. METHODS: All patients treated with S-IVL between October 2018 and January 2019 during their percutaneous coronary intervention (PCI) at our center were included...

BACKGROUND: Randomized trials of drug-eluting stents (DES) and drug-coated balloons (DCB) for femoropopliteal interventions reported superior patency rates for both strategies compared to standard balloon angioplasty. To date, head-to-head comparisons are missing. OBJECTIVES: The authors sought to compare DES versus DCB for femoropopliteal lesions through 36 months. METHODS: Within a multicenter, randomized trial, 150 patients with symptomatic femoropopliteal disease were randomly assigned to primary DES implantation or DCB angioplasty with bailout stenting after stratification for lesion length (≤10 cm, >10 cm to ≤20 cm, and >20 cm to ≤30 cm)...

BACKGROUND: The PSP (predilatation, sizing, post-dilatation)-technique was developed to improve the prognosis of patients after bioresorbable vascular scaffold (BVS) implantation. In acute coronary syndrome (ACS) the use of BVS is particularly demanding and carries some potential risk regarding aggressive lesion preparation, proper vessel sizing due to spasm and thrombus inside the artery. The aim herein, was to determine the long-term results of BVS stenting in ACS patients depending on the scaffold implantation technique...

REVIEW
Arpan R Doshi, Sathish Chikkabyrappa
Coarctation of aorta (CoA) is a discrete narrowing in aorta causing obstruction to the flow of blood. It accounts for 6-8% of all congenital heart diseases. With advances in fetal echocardiography rate of prenatal diagnosis of coarctation of aorta has improved but it still remains a challenging diagnosis to make prenatally. Transthoracic echocardiography is mainstay of making initial diagnosis and routine follow-up. Cardiac magnetic resonance imaging (MRI) and computed tomography (CT) are great advanced imaging tools for two-dimensional and three-dimensional imaging of aortic arch in complex cases...

Bioprosthetic leaflets made from animal tissues are used in the majority of surgical and transcatheter cardiac valve replacements. This study develops a new surgical bioprosthesis, using porcine pericardial leaflets. Porcine pericardium was obtained from genetically engineered pigs with a mutation in the GGTA-1 gene (GTKO) and fixed in 0.6% glutaraldehyde, and used to develop a new surgical valve design. The valves underwent in vitro hydrodynamic test in a pulse duplicator and high-cycled accelerated wear testing and were evaluated for acute haemodynamics and thrombogenicity in a juvenile sheep implant study for 48 h...

Intravascular ultrasound (IVUS) guidance is not routinely performed in real-word clinical practice partly because the benefit of IVUS guidance is not well established. This updated meta-analysis aims to compare IVUS-guided and angiography-guided drug-eluting stent (DES) implantation, simultaneously stressing the value of an optimal IVUS-defined procedure. Medline, Scopus, Google Scholar, and Cochrane Controlled Trials Registry were searched for the randomized trials comparing IVUS-guided and angiography-guided DES implantation...

Coronary revascularization, either percutaneous by stent implantation or surgical, has been established as the treatment of choice for patients with significant coronary stenosis. One of the main targets of coronary revascularization - especially in patients with stable disease - is to alleviate symptoms and thereby improve quality of life. Residual angina after successful coronary revascularization is not uncommon and indeed frustrating for the patient as much as for the treating physician. Several studies have shown worse outcomes in females with regard to post-revascularization morbidity and mortality in percutaneous as well as surgical coronary procedures...
