Transfemoral transcatheter aortic valve-in-valve implantation using endoconduit in a patient with right-sided aortic arch and complex vascular anatomy: a case report.

Background: The number of transcatheter aortic valve implantation (TAVI) procedures has increased significantly and now includes younger and higher-risk surgical patients. As early-generation transcatheter heart valves (THVs) continue to degrade over time, the incidence of structural valve deterioration (SVD) is increasing, requiring more complex valve-in-valve (TAV-in-TAV) procedures.

Case Summary: We present a case of SVD of a THV, resulting in severe aortic regurgitation in an 88-year-old female with decompensated heart failure.

Positional Changes in Right Atrial Pressure Before and After PFO Closure in Platypnea-Orthodeoxia Syndrome.

Background: Platypnea-orthodeoxia syndrome (POS) is a rare condition; however, the number of reported cases has been increasing in recent years.

Case Summary: We present a case of POS caused by a patent foramen ovale (PFO), where oxygen saturation and right atrial pressure were measured in both the supine and the sitting positions before and after PFO closure. After closure, oxygen desaturation during postural changes resolved, but the increase in right atrial pressure persisted.

The ViaHole technique: a novel approach for recanalizing major side branch occluded by Viabahn stent-graft.

Introduction: In managing arterial rupture, stent-graft implantation may cause limb ischemia by crossing a major branch for hemostasis. The ViaHole technique could circumvent a major branch occlusion.

Materials And Methods: The process involved advancing retrograde devices into an occluded major branch by the stent-graft implantation to reach the outer surface of the stent-graft, puncturing the stent-graft with a 20-gauge needle to touch the retrograde device, manipulating the guidewire through the needle hole and externalizing it, advancing the microcatheter into the proximal lumen, catching the microcatheter using an antegrade 4-Fr catheter, inserting an antegrade guidewire into the retrograde microcatheter to cross the stent-graft hole, dilating the lesion and stent-graft hole using a 3.

Fracking compared to conventional balloon angioplasty alone for calcified common femoral artery lesions using intravascular ultrasound analysis: 12-month results.

Background: Fracking is a novel technique to crack calcified lesions by hydraulic pressure. This study aimed to compare the performance of fracking and conventional balloon angioplasty without stenting for calcified common femoral artery (CFA) lesions using intravascular ultrasound (IVUS) analysis.

Methods: This retrospective, single-center, comparative observational study included 59 patients (67 limbs) with calcified CFA lesions treated with either fracking (n = 30) or balloon angioplasty (n = 29) between January 2018 and December 2020.

Propensity score-matched analysis of six-month outcomes of paclitaxel-coated balloons combined with UltraScore balloons versus conventional scoring balloons for femoropopliteal lesions.

Purpose: Combination angioplasty with paclitaxel-coated balloons (PCBs) and conventional scoring balloons for femoropopliteal lesions has demonstrated satisfactory results, even for complex lesions. The UltraScore balloon (Becton Dickinson, New Jersey, USA), which has a maximum length of 300 mm, has two longitudinal 0.010-inch stainless steel wires and is a new treatment option for complex femoropopliteal lesions.

Comparative 2-year outcomes of the Misago stent versus other self-expandable nitinol stents for the endovascular treatment of aortoiliac disease.

Background: The Misago iliac stent has not been compared with other stents. This study aimed to evaluate the 2-year clinical outcomes between the Misago stent and other self-expandable nitinol stents for symptomatic chronic aortoiliac disease.

Methods: This retrospective, single-center observational study enrolled 138 patients (180 limbs; Rutherford classification, between categories 2 and 6) treated with a Misago stent (N.

Synthesis and Structure-Photophysics Evaluation of 2-N-Amino-quinazolines: Small Molecule Fluorophores for Solution and Solid State.

2-N-aminoquinazolines were prepared by consecutive S Ar functionalization. X-ray structures display the nitrogen lone pair of the 2-N-morpholino group in conjugation with the electron deficient quinazoline core and thus representing electronic push-pull systems. 2-N-aminoquinazolines show a positive solvatochromism and are fluorescent in solution and in solid state with quantum yields up to 0.
