The pathophysiologic side effects of cardiopulmonary bypass have already been identified. Minimally invasive extracorporeal circulation technologies (MiECT) and off-pump coronary artery bypass graft surgery (OPCABG) aim to reduce these problems. This metaanalysis provides a comparison of MiECT and OPCABG in randomized and observational studies. A fully probabilistic, Bayesian approach of primary and secondary endpoints was conducted. MiECT does not give inferior results when compared with OPCABG. However, there is a trend to borderline significantly higher blood loss in this group in randomized controlled trials...

BACKGROUND: Our objective was to determine whether the choice of a HeartWare HVAD as opposed to a Heartmate II left ventricular assist device (HMII LVAD), impacts survival after heart transplantation after controlling for patient, donor, and center characteristics. METHODS: We queried the United Network for Organ Sharing (UNOS) database, which has recently made pretransplantation device duration available, for all adult patients undergoing bridge to transplantation (BTT) between January 2011 and March 2016...

BACKGROUND: Localization of small, nonvisible and nonpalpable nodules is challenging during video-assisted thoracoscopic surgery. We evaluated the feasibility of using a new ultrasound thoracoscope to localize nodules in resected ex vivo human lungs. METHODS: The tumor was localized and measured in its greatest dimension with a prototype ultrasound thoracoscope (XLTF-UC180; Olympus Corporation, Tokyo, Japan) at different frequencies (5.0 to 12.0 MHz) and different lung specimen states (deflated, semiinflated)...

BACKGROUND: Smaller transcatheter aortic valve replacement (TAVR) delivery systems have increased the number of patients eligible for transfemoral procedures while decreasing the need for transaortic (TAo) or transapical (TA) access. As a result, newer TAVR centers are likely to have less exposure to these alternative access techniques, making it harder to achieve proficiency. The purpose of this study was to evaluate the learning curve for TAVR approaches and compare perioperative outcomes...

Controversies remain on the increased rate of neurological events after small thoracotomy mitral valve surgery attributed to endoaortic balloon occlusion (EABO). Systematic literature search of databases identified 17 studies enrolling 6,643 patients comparing safety and effectiveness of EABO versus transthoracic clamp. In a meta-analysis, there was no difference in occurrence of cerebrovascular events, all-cause mortality, and kidney injury. EABO was associated with a significantly higher risk of iatrogenic aortic dissection (0...

BACKGROUND: Intracavitary pulmonary aspergilloma is a chronic, debilitating fungal infection. Without definitive therapy, death can occur from massive hemoptysis, cachexia, or secondary infection. Although surgical resection is the standard therapy, it is not possible for many patients owing to poor pulmonary function or medical comorbidities. Aspergilloma removal through bronchoscopy is an important alternative therapy that may be available in select cases. METHODS: We retrospectively reviewed all cases referred to the University of Calgary Interventional Pulmonary Service for transbronchial removal of intracavitary aspergilloma from January 1, 2009, to January 1, 2014...

BACKGROUND: Lung carcinoma is often associated with interstitial lung disease (ILD), and the prognosis of lung cancer accompanied by ILD is unfavorable. In this study, cases of patients with primary lung cancer with or without ILD were reviewed to analyze surgical outcome, with special interest in the conformity of clinical and pathologic stages, pathologic findings of pleural invasion, malignant pleurisy first detected at the time of thoracotomy, and survival. METHODS: Retrospective chart review was performed for 1,264 primary lung cancer patients who underwent surgery from 2004 to 2015...

BACKGROUND: Macroscopic complete surgical resection with adjuvant chemotherapy can provide a survival advantage in patients with malignant pleural mesothelioma (MPM). Patients with nonepithelioid histology are largely excluded from such radical operations even though they might benefit. The degree of epithelioid differentiation varies in biphasic histology. We report the outcomes of pleurectomy and decortication and the effect of epithelioid differentiation on overall survival of patients with MPM...

BACKGROUND: Progressive autograft dilatation after a Ross operation suggests that remodeling does not effectively reproduce native aortic root biomechanics. In the first of this two-part series, we compared mechanical properties of explanted autografts to pulmonary roots at pulmonary pressures. The goal of this study was to compare mechanical properties of explanted autografts to native aortic roots at systemic pressures. METHODS: Autograft specimens were obtained from patients undergoing reoperation after Ross operation...

BACKGROUND: Concerns have been raised regarding the toxicity of neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer that could contribute to an increased risk of postoperative complications. The aim of this study was to determine the influence of the radiation dose to the gastric fundus on the risk of postoperative anastomotic leakage in patients undergoing nCRT followed by transthoracic esophagectomy. METHODS: Between January 2012 and July 2015, 97 consecutive patients who underwent nCRT followed by transthoracic esophagectomy were included in this single-center cohort study...

BACKGROUND: Left pulmonary artery (LPA) stenosis with acute angulation is a common cause of reoperation after tetralogy of Fallot repair. We therefore investigated surgical outcomes of acute-angle correction angioplasty. METHODS: Between 2005 and 2012, 53 patients underwent operation for LPA stenosis as a concurrent procedure. We divided the patients into two groups according to the LPA ostium angulation: group I (acute angle, acute-angle correction angioplasty, n = 29) and group II (obtuse angle, conventional patch angioplasty, n = 24), encompassing subgroup type I (focal stenosis) and type II (diffuse stenosis)...

BACKGROUND: Patients at intermediate risk (IR) according to The Society of Thoracic Surgeons risk score are today frequently oriented toward the transfemoral aortic valve replacement (TAVR) option. Our goal was to evaluate the best treatment strategies for IR patients with severe aortic stenosis. METHODS: Of a consecutive series of 1,144 surgical aortic valve replacements (AVRs) performed in our institution between 2008 and 2014, we reviewed the early and late outcomes of two different groups: a low-risk (LR) group of 470 patients, and an IR group of 620...

BACKGROUND: Aortic root aneurysm can be treated with valve-sparing procedures. The David and Yacoub techniques have shown excellent long-term results but are technically demanding. Recently, a new and simpler procedure, the Sleeve technique, was proposed with encouraging results. We aimed to quantify the biomechanics of the initially aneurysmal aortic root (AR) after the Sleeve procedure to assess whether it induces abnormal stresses, potentially undermining its durability. METHODS: Two finite element (FE) models of the physiologic and aneurysmal AR were built, accounting for the anatomical asymmetry and the nonlinear and anisotropic mechanical properties of human AR tissues...

BACKGROUND: Atrial fibrillation (AF) occurs in 30% of patients with mitral regurgitation referred for surgical intervention. However, the underlying mechanisms in this population are poorly understood. This study examined the effects of acute left atrial volume overload on atrial electrophysiology and the inducibility of AF. METHODS: Ten canines underwent insertion of an atrioventricular shunt between the left ventricle and left atrium. Shunt and aortic flows were calculated, and the shunt was titrated to a shunt fraction to 40% to 50% of cardiac output...

BACKGROUND: Rho-kinase, an intracellular serine/threonine kinase, is a key regulator of cytoskeletal dynamics. Recent studies have demonstrated that Rho-kinase is involved in the ischemia-reperfusion injury (IRI) pathogenesis of many organs; however, its involvement with lung IRI remains unclear. This study assessed the association of Rho-kinase with lung IRI and evaluated the protective effect of inhaled Rho-kinase inhibitors in lung IRI. METHODS: The study included isolated rat lung perfusion models, divided into three groups: sham, Rho-kinase inhibitor, and warm ischemia (n = 6 each)...

BACKGROUND: The programmed cell death-ligand 1 (PD-L1) pathway plays an important role in maintaining immune homeostasis. The PD-L1 pathway may also protect tumors from attack by cytotoxic T cells. Blockade of programmed cell death 1 (PD1) or PD-L1 induced durable tumor regression in patients with advanced cancers, including non-small cell lung cancer (NSCLC). However, the prognostic value of PD-L1 expression in patients with lung adenocarcinoma remains controversial. METHODS: A total of 112 patients with resected lung adenocarcinoma were included in the study...

BACKGROUND: Current recommendations of antithrombotic therapy for HeartMate II (HMII) patients include the use of both an anticoagulant and an antiplatelet agent. Because bleeding is still the most frequent adverse event, the TRACE (STudy of Reduced Anti-Coagulation/Anti-platelet Therapy in Patients with the HeartMatE II) study was initiated to evaluate the incidence of adverse events in HMII patients on reduced antithrombotic (RT) therapy. METHODS: HMII patients (n = 101) from nine centers were enrolled in the European arm of TRACE and were managed on a single anticoagulant (vitamin K antagonist) with no antiplatelet agents...
