Comparative Study
Transcatheter Aortic Valve Replacement Versus Aortic Valve Bypass: A Comparison of Outcomes and Economics.
Transcatheter aortic valve replacement (TAVR) is currently offered to patients who are high-risk candidates for conventional surgical aortic valve replacement. For the past 37 years, off-pump aortic valve bypass (AVB) has been used in elderly patients at our center for this similarly high-risk group. Although TAVR and AVB were offered to similar patients at our center, comparisons of clinical outcomes and hospital economics for each strategy were not reported. ⋯ TAVR and AVB relieve aortic stenosis and have similar and acceptable procedural mortality rates. AVB-treated patients had 1.75 times the STS risk score when compared with the TAVR cohort. Hospital charges for TAVR were nearly twofold those of AVB. Hospital reimbursement was similar, but AVB had two to four times the profit margin of TAVR. Longer follow-up for the TAVR cohort will determine whether survival is comparable to that after AVB at 3 and 5 years.

A Fontan Y-shaped graft using a commercially available aortoiliac graft has been used to connect the inferior vena cava (IVC) to the pulmonary arteries. This modification of the Fontan procedure seeks to improve hepatic flow distribution (HFD) to the lungs. However, patient-specific anatomical restrictions might limit the space available for graft placement. Altering the superior vena cava (SVC) positioning is hypothesized to provide more space for an optimal connection, avoiding caval flow collision. Computational modeling tools were used to retrospectively study the effect of SVC placement on Y-graft hemodynamics. ⋯ SVC positioning with respect to the Y-graft affects HFD, especially in patients with lower IVC flow. Careful positioning of the SVC at the time of a bidirectional Glenn (BDG) procedure based on patient-specific anatomy can optimize the hemodynamics of the eventual Fontan completion.

Comparative Study Observational Study
Survival After Extracorporeal Cardiopulmonary Resuscitation on Weekends in Comparison With Weekdays.
Extracorporeal cardiopulmonary resuscitation (ECPR) requires urgent decision-making and high-quality skills, which may not be uniformly available throughout the week. Few data exist on the outcomes of patients with cardiac arrest who receive in-hospital ECPR on the weekday versus weekend. Therefore, we investigated whether the outcome differed when patients with in-hospital cardiac arrest received ECPR during the weekend compared with a weekday. ⋯ ECPR on the weekend was associated with a lower survival rate and lower resuscitation quality, including higher cannulation failure and higher complication rate.

A Predictive Score for Bronchopleural Fistula Established Using the French Database Epithor.
Bronchopleural fistula (BPF) remains a rare but fatal complication of thoracic surgery. The aim of this study was to develop and validate a predictive model of BPF after pulmonary resection and to identify patients at high risk for BPF. ⋯ This strong model could be easily used by surgeons to identify patient at high risk for BPF. This score needs to be confirmed prospectively in an independent cohort.

The use of administrative data for surgical site infection (SSI) surveillance leads to inaccurate reporting of SSI rates [1]. A quality improvement (QI) initiative was conducted linking clinical registry and administrative databases to improve reporting and reduce the incidence of SSI [2]. ⋯ Linkage of registry and infection control surveillance data with the EHR improves SSI surveillance. The visualization tool and workflow changes facilitated communication, SSI adjudication, and assessment of the QI initiatives. Implementation of these initiatives was associated with decreased SSI rates.
