Objectives: This study sought to evaluate the outcomes and factors associated with aborted procedures among patients undergoing elective transcatheter aortic valve replacement (TAVR).
Background: Elective TAVR procedures can be aborted because of device limitations or aborted for other reasons, including patient and procedural factors. Little is known about 30-day outcomes and factors associated with aborted procedures and procedures aborted because of device limitations (ADs).
Methods: Patients undergoing elective TAVR procedures from 2011 to 2017 in the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry were examined. The incidence of aborted procedures, both ADs and procedures aborted for other reasons (AOs), was examined. Rates of 30-day all-cause death or stroke and a composite of vascular complications and bleeding events were compared between patients with and those without aborted procedures and between patients with ADs and those with AOs. Multivariate modeling identified factors associated with aborted procedures and ADs.
Results: Among 106,169 patients who underwent TAVR between 2011 and 2017, procedures were aborted in 1,150 (1.1%) (581 ADs and 569 AOs). Patients with aborted procedures were more likely female with peripheral artery disease and more often treated at lower volume centers compared with those with nonaborted procedures (p < 0.01 for all). The incidence of aborted procedures and ADs decreased over the study period (p < 0.01). The adjusted rates of 30-day death and stroke were greater for aborted versus nonaborted procedures (odds ratio: 5.02; 95% confidence interval: 4.13 to 6.11). Peripheral artery disease, alternative access, and low institutional TAVR volume were factors associated with aborted procedures and ADs (p < 0.05 for all).
Conclusions: The incidence of aborted procedures is declining, but peripheral artery disease and low institutional TAVR volume remain associated with aborted procedures. A thorough pre-procedural assessment and referral of challenging cases to high-volume centers may be strategies to minimize aborted procedures.

Background: One potential cause of implantation failure is abnormal endometrial receptivity, and how to objectively evaluate endometrial receptivity has been a matter of great concern. Endometrial receptivity analysis (ERA), a next-generation sequencing-based test that assesses endometrial gene expression, may be valuable in predicting endometrial receptivity, but whether ERA improves pregnancy outcomes in patients with recurrent implantation failure (RIF) is currently controversial. The purpose of this study was to investigate the effect of ERA on pregnancy outcomes in patients with RIF.

Purpose: We report the use of a pericapsular nerve group (PENG) cryoneurolysis for longer-term analgesia in a patient with a hip fracture and severe medical comorbidities as an alternative to hip fracture surgery.
Clinical Features: A frail but lucid and fully autonomous 97-yr-old female from an assisted living facility sustained a subcapital fracture of her right proximal femur following a ground level fall. She had significant comorbidities including end-stage respiratory disease.

The protozoan parasite Neospora caninum is an important cause of abortion in cattle. Infection occurs horizontally by ingestion of oocysts shed by canids or vertically, from an infected dam to the foetus, and may result in abortion, stillbirth, or the birth of subclinically infected offspring. We estimated the occurrence of N.
