Multicenter Study
The association of chronic lung disease with early mortality and respiratory adverse events after aortic valve replacement.
We studied the association between components of chronic lung disease (CLD) assessment and operative outcomes in patients undergoing aortic valve replacement (AVR) for aortic stenosis. ⋯ CLD is associated with adverse operative outcomes in selected patients with aortic stenosis undergoing AVR. FEV1, DLCO, and PaO2 may add important information to current risk adjustment models beyond the broad CLD classification.

An impending paradoxical embolism is a rare finding, with fewer than 200 cases being documented so far. A 68-year-old woman, who presented with 3 weeks of increasing exertional dyspnea and exercise intolerance, underwent transesophageal echocardiography with a finding of an embolus in both right and left atria. ⋯ The thrombus was removed intact, and the foramen ovale was closed. By our experience, an emergent cardiac surgery should always be considered as a treatment option for impending paradoxical embolism.

Thoracic endovascular aortic repair (TEVAR) for chronic DeBakey IIIb dissection with associated descending aneurysm remains controversial. This study examines long-term results of TEVAR for this disorder including examination of anatomic features associated with TEVAR outcomes. ⋯ Thoracic endovascular aortic repair is effective for chronic DeBakey IIIb dissection with associated descending aneurysm, with excellent 30-day and long-term outcomes and significant aortic remodeling in the vast majority of patients. Thoracic remodeling does not appear dependent on distal anatomic characteristics of the true and false lumens, although care should be taken to cover all thoracic fenestrations and avoid creation of stent graft-induced new entry tears to ensure clinical success. Complete aortic remodeling was observed only in the setting of all visceral vessels off the true lumen with fewer than three residual distal fenestrations, and this would appear the ideal anatomy for TEVAR in this scenario.

A 64-year-old woman underwent tracheal sleeve resection for adenocarcinoma. Thirteen months later minimal granuloma occurred at the anastomosis. Subsequently she had dyspnea from obstruction caused by the increasing size of the granuloma, which necessitated 4 repeated endobronchial debulking procedures and topical mitomycin C (MMC) application. ⋯ Eventually, the granulation tissue and pledgeted sutures were removed from the anastomotic site using rigid bronchoscopy. Follow-up after 8 months showed no recurrence of symptoms, and the granuloma had resolved. Despite improvements in surgical suture material, removal of stitches should still be considered in the management of anastomotic obstruction caused by indolent and intractable granulation after tracheal resection or bronchoplasty.

Extracorporeal membrane oxygenation (ECMO) support is often required in the management of perioperative congenital heart surgery (CHS) patients. However, 24-hour in-hospital congenital cardiac surgical coverage (24-CCSC) is not available at all institutions. The purpose of this study is to evaluate the effect of 24-CCSC on perioperative ECMO outcomes in CHS patients. ⋯ The presence of 24-CCSC significantly decreased the rate of mortality in children supported with ECMO after undergoing cardiac surgery, as well as cardiac arrhythmias and pulmonary complications for perioperative CHS patients receiving ECMO support. This study demonstrates that CHS programs would benefit from 24-CCSC in the care of this critically ill patient population.
