Multicenter Study
Use of One-Way Intrabronchial Valves in Air Leak Management After Tube Thoracostomy Drainage.
A persistent air leak represents significant clinical management problems, potentially affecting morbidity, mortality, and health care costs. In 2008, a unidirectional, intrabronchial valve received humanitarian device exemption for use in managing prolonged air leak after pulmonary resection. Since its introduction, numerous reports exist but no large series describe current utilization or outcomes. Our aim was to report current use of intrabronchial valves for air leaks and review outcome data associated with its utilization. ⋯ We present the largest, multicenter study of patients undergoing evaluation for intrabronchial valve use for air leak management. Our data suggest the majority of intrabronchial valve placements are occurring for off-label indications. Although the use of intrabronchial valves are a minimally invasive intervention for air leak management, the lack of rigorously designed studies demonstrating efficacy remains concerning. Prospective randomized controlled studies remain warranted.

Comparative Study
Myocardial Revascularization Exclusively With Bilateral Internal Thoracic Arteries in T-Graft Configuration: Effects on Late Survival.
We studied long-term survival using bilateral internal thoracic artery (BITA) grafting in a T-configuration exclusively versus using single internal thoracic artery (SITA) grafting in patients with multivessel disease. ⋯ This study suggests that coronary artery operations exclusively with BITA grafting in a T-configuration may be associated with better long-term survival than grafting with SITA plus other types of conduits.

Aberrant flow pattern and congenital fragility bestows bicuspid aortic valve (BAV) with a propensity toward ascending aorta dilatation, aneurysm, and dissection. Whether isolated aortic valve replacement (AVR) can prevent further dilatation in BAV ascending aorta and what indicates concurrent aortic intervention in the case of valve operation remain controversial. ⋯ An aggressive policy of preventive aortic interventions seemed appropriate in patients with BAV-AI during AVR, and BAV phenotype presenting as either insufficiency or stenosis should be taken into consideration when contemplating optimal surgical strategies for BAV aortopathy.

Outcomes of surgical intervention for severe tricuspid regurgitation related to Ebstein anomaly or tricuspid valve dysplasia in the neonatal period, particularly when associated with pulmonary atresia, are extremely poor. However, owing to emerging innovative surgical techniques, such as cone reconstruction, outcomes of tricuspid valve plasty in the neonatal period have gradually improved. ⋯ Biventricular repair with cone reconstruction can be applied for severe tricuspid regurgitation due to neonatal Ebstein anomaly or tricuspid valve dysplasia with associated pulmonary atresia. A tricuspid regurgitation flow velocity greater than 3.0 m/s may be an indicator of successful biventricular repair.

This study evaluated the role of multidetector computed tomography (MDCT) in preparation for minimally invasive aortic valve replacement (MIAVR). ⋯ Preoperative MDCT of the thorax, aorta, and femoral arteries makes it possible to plan MIAVR operations.
