Comparative Study
Favorable outcomes for multidrug and extensively drug resistant tuberculosis patients undergoing surgery.
New approaches are needed in the treatment of multidrug-resistant and extensively drug-resistant pulmonary tuberculosis (M/XDR-PTB). We evaluated the role of adjunctive surgical therapy in the treatment of M/XDR-PTB in the setting of directly observed treatment strategy (DOTS)-Plus implementation. ⋯ Patients with M/XDR-PTB undergoing adjunctive thoracic surgery had high rates of favorable outcomes, no surgical-related mortality, and low rates of complications. Adjunctive surgery appears to play an important role in the treatment of select patients with M/XDR-PTB.

Comparative Study
Tricuspid reoperation after left-sided rheumatic valve operations.
The management of late tricuspid regurgitation after left-sided valve operations in rheumatic patients remains controversial. The aim of this study was to analyze clinical and echocardiographic outcomes of tricuspid valve procedures after left-sided valve operations in rheumatic patients. ⋯ Tricuspid valve procedures after left-sided valve operations in rheumatic patients can be performed at low risk with good clinical outcomes. For improved clinical outcomes, early surgical intervention should be considered before the development of anemia and left ventricular dysfunction. A lower aortic transprosthetic mean pressure gradient may help prevent late progression of tricuspid regurgitation in a clinical setting.

Comparative Study
Arterial switch for transposition with left outflow tract obstruction: outcomes and risk analysis.
The long-term results and indications of the arterial switch operation (ASO) for transposition of the great arteries (TGA) and anatomic left ventricular outflow tract obstruction (LVOTO) remain undetermined. The aims of this study were to determine long-term outcomes and prognostic factors in this specific population. ⋯ Long-term outcomes of ASO for patients with TGA and anatomic LVOTO are satisfactory in selected patients. A lower preoperative pulmonary valve z-score and complex multilevel atrioventricular valve-related LVOTO are independent predictors of recurrent LVOTO and LVOT reoperation. TGA/LVOTO patients with pulmonary valve z-score exceeding -1.8 and resectable valvular or subvalvular LVOTO, or both, should be candidates for ASO, regardless of the severity of the LVOT peak gradient.

Comparative Study
Outcomes before and after implementation of a pediatric rapid-response extracorporeal membrane oxygenation program.
Rapid-response extracorporeal membrane oxygenation (RR-ECMO) has been implemented at select centers to expedite cannulation for patients placed on ECMO during extracorporeal cardiopulmonary resuscitation (ECPR). In 2008, we established such a program and used it for all pediatric venoarterial ECMO initiations. This study was designed to compare outcomes before and after program implementation. ⋯ Implementation of a pediatric RR-ECMO program for venoarterial ECMO initiation was associated with reduced neurologic complications but not improved survival during the first 3 years of program implementation. These data suggest that development of a coordinated system for rapid ECMO deployment may benefit both ECPR and non-ECPR patients, but further efforts are required to improve survival.

Comparative Study
Results with selective preoperative lumbar drain placement for thoracic endovascular aortic repair.
The optimal use of lumbar cerebrospinal fluid drainage for the prevention of spinal cord ischemia (SCI) with thoracic endovascular aortic repair (TEVAR) remains unclear. Here, we report our experience with selective preoperative lumbar drain placement with TEVAR. ⋯ Restricted use of preoperative lumbar drains for patients at high-risk of SCI undergoing TEVAR appears safe and leads to low rates of SCI in nondrained patients. However, the utility of preoperative lumbar drains in preventing SCI with TEVAR remains questionable and should be weighed against the risk of drain complications.
