This study sought to identify the changing characteristic patterns and locations of stenosis after tracheostomy or intubation and to assess the risk factors associated with perioperative complication and restenosis after primary resection and reconstruction. ⋯ Recent advances in percutaneous tracheostomy have increased the numbers of patients presenting with proximal tracheal stenosis, thus necessitating more complex subglottic resection and reconstruction. The anastomotic and overall complication rate remains low despite these more complex operations.

Severe Tricuspid Regurgitation After Percutaneous Removal of a Swan-Ganz Catheter Caught by Suture.
Swan-Ganz catheter entrapment in the heart, vena cava, or pulmonary artery is rare but may lead to life-threatening events. We report a case of severe tricuspid regurgitation resulting from papillary muscle rupture during percutaneous removal of a Swan-Ganz catheter (SCG) caught by a surgical suture. We performed urgent tricuspid valve repair by suturing the ruptured papillary muscle. This report highlights preventive measures to avoid suture-related entrapment and raises a word of caution regarding percutaneous removal of accidentally entrapped SCGs.

Hypothermia and Selective Antegrade Cerebral Perfusion Is Safe for Arch Repair in Type A Dissection.
Unilateral selective antegrade cerebral perfusion with moderate hypothermic circulatory arrest has been shown to be a safe and effective method of cerebral protection during surgery for acute type A dissection. This study evaluates the impact of this cerebral protection strategy on clinical outcomes after extended aortic arch reconstruction in patients undergoing emergent repair of acute type A dissection. ⋯ Unilateral selective antegrade cerebral perfusion with moderate hypothermic circulatory arrest remains a safe strategy for cerebral protection during emergent surgical repair of acute type A dissection and provides equivalent outcomes for both limited and extensive aortic arch reconstruction. Based on these data, unilateral selective antegrade cerebral perfusion and moderate hypothermic circulatory arrest may represent an optimal strategy for cerebral protection in this acute setting.

The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS CHSD) is the largest congenital and pediatric cardiac surgical clinical data registry in the world. It contains data pertaining to more than 435,000 total operations. The most recent biannual feedback report to participants (Spring 2017, Report of the Twenty-Sixth Harvest) included analysis of data submitted from 127 hospitals in North America. ⋯ Additional publications reported the most recent development, evaluation, and application of metrics for quality measurement and reporting of pediatric and congenital heart operation outcomes and center level performance. Use of the STS CHSD for outcomes research and for quality measurement continues to expand as database participation has grown to include nearly all centers in North America, and the available wealth of data in the database continues to grow. This article reviews outcomes research and quality improvement articles published in 2016 that are based on STS CHSD data.

Risk Index for Postoperative Acute Kidney Injury After Valvular Surgery Using Cardiopulmonary Bypass.
Acute kidney injury (AKI) after valvular surgical procedures with cardiopulmonary bypass carries potentially high mortality and morbidity rates. This study investigated the risk factors for AKI, and the study investigators developed a risk index to predict postoperative AKI. ⋯ Based on these risk factors, the study investigators were able to predict the postoperative incidence of renal dysfunction after valvular operations with cardiopulmonary bypass.
