We investigated the incidence and causes of unplanned hospital readmissions after continuous-flow (CF) left ventricular assist device (LVAD) implantation. We also analyzed the impact of unplanned readmissions on post-CF-LVAD survival and the costs associated with each cause of readmission. ⋯ Gastrointestinal bleeding and CF-LVAD-related infections were the leading causes of readmission. Patients with a CF-LVAD spent 93% of their time out of hospital after implantation, and readmissions did not have a negative impact on long-term survival. New approaches to minimize these adverse events will continue to improve the efficacy and decrease the cost of CF-LVAD therapy.

Clinical Trial
Pulmonary Artery Sealing Using the HARMONIC ACE+ Shears for Video-Assisted Thoracoscopic Surgery Lobectomy.
The standard technique for pulmonary arterial (PA) branch sealing in video-assisted thoracoscopic surgery lobectomy consists of vascular endostaplers. We evaluated the immediate efficacy of an ultrasonic energy vessel-sealing device for sealing PA branches and compared it with the gold standard (endostapler) in an ex vivo model. ⋯ PA branches sealed using the HARMONIC ACE+ in a simulated ex vivo model were able to sustain high intraluminal pressures. ACE-sealed vessels burst at mean bursting pressures equal to or greater than the VES-stapled vessels.

This study's objective was to develop a risk model incorporating procedure type and patient factors to be used for case-mix adjustment in the analysis of hospital-specific operative mortality rates after congenital cardiac operations. ⋯ The risk model is well suited to adjust for case mix in the analysis and reporting of hospital-specific mortality for congenital heart operations. Inclusion of patient factors added useful discriminatory power and reduced bias in the calculation of hospital-specific mortality metrics.

Impact of Patient Characteristics on Hospital-Level Outcomes Assessment in Congenital Heart Surgery.
Accurate hospital outcome measures in congenital heart surgery are important to multiple initiatives. While methods have been developed to account for differences in procedural case-mix, characteristics patients bring into the operation that may also vary across hospitals and influence outcome have received less attention. We evaluated the impact of these characteristics in a large cohort. ⋯ Characteristics of patients undergoing congenital heart surgery vary across centers and impact hospital outcomes assessment. Methods to assess outcomes and relative performance should account for these characteristics.

In this study we derive and validate a composite risk index termed the Assessment of Thoracic Endografting Operative Mortality, or ATOM, risk score. ⋯ The ATOM score is a significant predictor of operative mortality in TEVAR and can be used for preoperative risk stratification.
