Valve-sparing aortic root replacement is one of the effective repairs for aortic regurgitation resulting from progressive dilatation of the aortic root late after surgical correction of conotruncal anomaly. However, feasibility and effectiveness of this procedure are unknown for unrepaired physiology. ⋯ Six months after the surgical procedure, aortic regurgitation remained trivial. Concomitant valve-sparing aortic root replacement with TOF repair can be feasible and effective for unrepaired TOF with aortic regurgitation.

Multicenter Study
Utilization of Minimally Invasive Thymectomy and Margin-Negative Resection for Early-Stage Thymoma.
Minimally invasive thymectomy (MIT) has demonstrated improved short-term outcomes compared with open thymectomy (OT). Although adoption of MIT for thymoma is increasing, oncologic outcomes have not been well characterized. ⋯ The use of MIT for resection of early-stage thymoma is increasing and is not associated with lower rates of R0 resection than OT. Reasons for the relatively low rates of R0 resection among all thymectomies requires further investigation, and long-term outcomes data are needed to better define the oncologic effectiveness of MIT.

The Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model adjusts not only for procedure and age group pairings but also for additional patient factors, including the binary presence or absence of a chromosomal abnormality (CA), syndrome (S), and/or a noncardiac congenital anatomic abnormality (NCAA). This analysis refines case-mix adjustment by adding more granular adjustment for individual conditions (CA, S, and NCAA), consistent with a hypothesis that associated risk of mortality differs between individual conditions. ⋯ The Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model has been augmented by addition of covariates representing individual CAs, Ss, and NCAAs.

The use of short-term mechanical circulatory support (ST-MCS) has increased for refractory cardiogenic shock. However, there are scant data about bridge-to-recovery patients. ⋯ The overall midterm outcome of patients explanted from ST-MCS is favorable except for AMI patients.

This study directly compared outcomes of transcatheter aortic valve-in-valve insertion (TAVI-in-valve) with repeat surgical aortic valve replacement (SAVR) for failing stented aortic biological prostheses. ⋯ TAVI-in-valve and repeat SAVR can be done with similar operative and intermediate-term mortality. SAVR results in better hemodynamic function and thus appears the preferred option.
