Abstract Background Retrograde false lumen (FL) perfusion after thoracic endovascular aortic repair (TEVAR) for chronic dissection is a mode of treatment failure. Thrombosis of the FL is associated with favorable reverse remodeling. Objectives are to describe false lumen embolization (FLE) strategy, assess aortic remodeling and survival. Methods From 1/2009 to 12/2017, 51 patients with chronic dissection underwent FLE, most after previous TEVAR. Devices included a combination of: iliac plug (29 ...
ABSTRACT Calcifying fibrous tumors (CFTs) are rare lesions that occur throughout the body. A 35-year-old man presented with exertional dyspnea. Computed tomography showed a polypoid mass abutting pericardium, diaphragm, and left chest wall, and a pleural-based lesion adjacent to T12. Thoracoscopy revealed a large mass with diaphragmatic stalk, two pleural-based nodules and four diaphragmatic nodules. Pathological analysis of resected lesions showed CFT. Three lesions contained heterogenous mutat...
The Thoracic Surgery Residents Association (TSRA) was established in 1997 as a trainee-led organization under the guidance of the Thoracic Surgery Directors Association (TSDA) to represent the interests and meet the educational needs of cardiothoracic surgery residents across North America. Since its founding, the TSRA has continuously evolved and expanded to further its primary mission. In addition to now offering text- and audio-based educational resources, the TSRA acts to connect students, t...

ABSTRACT Double annular enlargement (DAE) is a valuable technique for the cardiac surgeon, and it should be in his/her armamentarium when dealing with challenging aortic and mitral valve cases. The technique requires reconstruction of the intervalvular fibrosa and it redesigns the inflow and the outflow of the left ventricle in a way that serves both annular enlargement and satisfactory valve replacement with resulting low gradients. Below, we describe our preferred operative steps.
ABSTRACT Background Despite the superiority of mitral valve repair (MVr) over replacement for degenerative disease, repair rates vary widely across centers. Traveling to a Mitral Reference Center (MRC) is one way to increase the odds of MVr. This study assessed the economic value (quality/cost) and long-term outcomes of distant referral to a MRC. Methods Among 746 mitral surgery patients between January 2011–June 2013, low-risk patients with ejection fraction>40% undergoing isolated degenerative...
Abstract Background Contradictory findings from randomized trials addressing similar research questions are not uncommon in medicine. While differing results may reflect true differences in the treatment effects or in the deliverability of the intervention, more commonly it is as a consequence of small but important discrepancies in study design. Methods The writing group selected four recent trials with apparently contradictory results (two on revascularization for left main coronary stenosis a...
Abstract Spontaneous thrombosis in the aortic arch is a rare finding in the neonate, associated with a mortality rate exceeding 50%1. Often, the thrombosis is initially interpreted as arch obstruction secondary to coarctation or interrupted aortic arch. Thus, the obstruction is mechanical with no structural abnormality. We describe two newborns with coarctation and extensive thrombosis within the aortic arch. We report their successful surgical management, with a brief review of the literature a...
Aortic valve sparing operations are meant to stabilize the root in order to provide stable aortic valve function. The possibility of graft dilatation has been known in other forms of aortic replacement, but is largely ignored in valve-preserving surgery. We describe graft dilatation as a cause of failure late after aortic valve reimplantation. It was corrected by applying the concepts of aortic valve repair.
Abstract Background We investigated changes in estimated glomerular filtration rate (eGFR) post LVAD implant and the impact on long term outcomes. Methods A retrospective analysis was conducted for 255 LVAD. They were divided into two groups based on pre-implant eGFR ( 60 ml/min/1.73 m2) and into 6 grades (Grade1:> 90 ml/min/1.73 m2 normal, 2: 60-89 mild dysfunction, 3: 45- 59 moderate, 4: 30- 44 moderate to severe, 5 :15- 29 severe, 6: Results One-month post-implant eGFR of the total cohort inc...
