LAA clipping during thoracoscopic ablation is a feasible and safe technique for closure of the LAA in patients with atrial fibrillation. The lower than expected rate of cerebrovascular events after deployment was likely multifactorial, including not only LAA closure, but also the effect of oral anticoagulation and rhythm control.
A 61-year-old male patient was referred for lead extraction of an infected two-chamber pacemaker system first implanted 18 years ago. A new atrial lead was implanted 9 years later because of loss of capture of the original lead. Video-assisted thoracoscopic surgery (VATS) that we use in high-risk cases showed extensive fibrous adhesion between the right atrium wall and the right lung. Dissection of the adhesion revealed the presence of an atrial lead perforated into the lung. After cutting off the lead tip, the residual lead was removed endovascularly from the subclavian site. A literature review of 25 reported cases of late atrial lead perforation was added to the findings in our case report.
OBJECTIVES
This study sought to evaluate the long-term differences in survival between multiple arterial grafts (MAG) and single arterial grafts (SAG) in patients who underwent coronary artery bypass grafting (CABG) in the SYNTAX study.
METHODS
The present analysis included the randomized and registry-treated CABG patients (n = 1509) from the SYNTAX Extended Survival study (SYNTAXES). Patients with only venous (n = 42) or synthetic grafts (n = 1) were excluded. The primary end point was all-cause death at the longest follow-up. Multivariable Cox regression was used to adjust for differences in baseline characteristics. Sensitivity analysis using propensity matching with inverse probability for treatment weights was performed.
RESULTS
Of the 1466 included patients, 465 (31.7%) received MAG and 1001 (68.3%) SAG. Patients receiving MAG were younger and at lower risk. At the longest follow-up of 12.6 years, all-cause death occurred in 23.6% of MAG and 40.0% of SAG patients [adjusted hazard ratio (HR) 0.74, 95% confidence interval (CI) (0.55–0.98); P = 0.038], which was confirmed by sensitivity analysis. MAG in patients with the three-vessel disease was associated with significant lower unadjusted and adjusted all-cause death at 12.6 years [adjusted HR 0.65, 95% CI (0.44–0.97); P = 0.033]. In contrast, no significance was observed after risk adjustment in patients with the left main disease, with and without diabetes, or among SYNTAX score tertiles.
CONCLUSIONS
In the present post hoc analysis of all-comers patients from the SYNTAX trial, MAG resulted in markedly lower all-cause death at 12.6-year follow-up compared to a SAG strategy. Hence, this striking long-term survival benefit of MAG over SAG encourages more extensive use of multiple arterial grafting in selected patients with reasonable life expectancy.

This relatively simple, low-cost, low-fidelity model can provide simulation training in nearly the full range of mitral valve and tricuspid valve surgical techniques, in both the classic open approach and the minimally invasive approach-and do so almost anywhere. Especially when used by young cardiothoracic surgeons in training, this model may contribute to the development of technical skills and procedural knowledge required for adequate performance in the operating room.
Partial anomalous pulmonary venous connection (PAPVC) is defined to exist when some but not all venous drainage enters the left atrium, while the remaining veins connect to the right-sided circulation. Scimitar syndrome is a specialized example, in which an anomalous pulmonary vein descends from the right lung and drains into the inferior caval vein. PAPVC is associated with sinus venosus-type atrial septal defect (ASD). Diagnosis was, in the past, based on echocardiographic imaging and could be difficult. Multislice spiral computed tomography and magnetic resonance imaging improved the imaging quality. The surgical correction is dependent on the type of anomalous connection and the presence of an ASD. Outcome is good but obstructed venous return is an important issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
