Failed valve-in-valve transcatheter mitral valve implantation [PDF]
European Journal of Cardio-Thoracic Surgery, 2014 A 73-year old man underwent trans-septal anterograde implantation of a 26-mm Sapien-XT valve (Edwards Lifesciences, CA, USA) to treat a degenerated 27-mm Carpentier-Edwards bioprosthesis. During the follow-up, the patient experienced severe haemolysis with moderate-to-severe inter-valvular leak, and fluoroscopy revealed possible incomplete apposition ...

Bioprosthetic valve fracture during valve-in-valve transcatheter aortic valve replacement [PDF]
Baylor University Medical Center Proceedings, 2020 Transcatheter aortic valve replacement (TAVR) valve-in-valve (VIV) therapy has been approved for select patients with surgically inoperable bioprosthetic valves that need replacement. Bioprosthetic valve fracturing (BVF) used in conjunction with VIV TAVR can reduce transvalvular gradients and increase the aortic valve area.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...

Misperception of Body Weight After Childhood Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Misperception of body weight can negatively impact the weight management efforts of childhood cancer survivors (CCSs). Both being overweight or underweight are associated with chronic health conditions commonly observed in CCS; therefore, accurate weight perception is critical for reducing long‐term health risks.

The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature
Pediatric Blood &Cancer, EarlyView.ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...
