We present a case of an accidentally crushed stent due to an unnoticed passage of a guidewire through a lateral stent strut with subsequent stent compression after balloon dilatation, during a planned percutaneous coronary intervention on the left main. The crushed stent segment was reconstructed with step-by-step balloon dilation, guided by intravascular ultrasound.

Abstract Introduction Valve-in-Valve transcatheter aortic valve implantation (ViV-TAVI) is an appealing treatment option for patients with degenerated bioprosthetic valves. However, high post-procedural transprosthetic gradients are very common after ViV-TAVI than TAVI native-valve stenosis. Aim We sought to evaluate (ΔP) and hemodynamic outcome in undergoing according type balloon post-dilatio...

OBJECTIVES This study evaluated the long-term impact of endoluminal low power red laser light (LPRLL) on restenosis in an atherosclerotic rabbit model. BACKGROUND Despite widespread application of balloon angioplasty for treatment of coronary artery disease, restenosis limits its clinical benefits. Restenosis is a complex process and may be partly attributed to the inability of the vascular e...

OBJECTIVES gastric bypass is the surgical procedure that is carried out most frequently in the treatment of morbid obesity. Stenosis of the gastro-jejunal anastomosis is a relatively frequent complication that requires endoscopic management. However, the optimal dilation technique is yet to be determined. The purpose of this study was to evaluate the safety and efficacy of dilation with a hydro...

BACKGROUND Ureteral tapering and reimplantation is an established treatment for persistent or progressive primary obstructive megaureter (POM) but may result in complications and morbidity. Use of a less invasive technique involving endoscopic balloon dilation appears very interesting. OBJECTIVE The objective of this report is to determine if endoscopic balloon dilation for POM is effective i...

BACKGROUND Percutaneous balloon pulmonary valvuloplasty (PBPV) is the preferred therapy for pulmonary valve stenosis (PVS). This study retrospectively reviewed recent PBPV outcomes in infants with PVS. The aim of this study was to evaluate factors associated with immediate therapeutic outcomes and restenosis during medium-term follow-up. METHODS The study included 158 infants with PVS who und...

Epidermolysis bullosa rarely affects lower airways. We present a case of lower airway involvement and stenosis successfully managed with flexible bronchoscopy and balloon dilation.

BACKGROUND Adequate expansion is critical to achieve optimal Bioresorbable Vascular Scaffolds (BVS) apposition to the vessel wall. However, compared to metallic stents, BVS present different mechanical properties. Hence, slow deployment and maintenance of balloon inflation for at least 30" is recommended for BVS implantation. However, since no evidences are available demonstrating the superiori...
