We present a rare late complication after inferior vena cava filter (IVC) placement. A 52-year-old woman with an IVC presented with sudden onset of chest pain. Cardiac catheterisation and echocardiography revealed an embolised IVC filter strut penetrating the right ventricle. Endovascular retrieval was considered but deemed unsafe due to proximity to the right coronary artery and concern for migration to pulmonary circulation. Urgent removal of the strut was performed via sternotomy. The postoperative course was uneventful...

BACKGROUND: New-onset postoperative atrial fibrillation (POAF) occurs in up to 30% of patients undergoing coronary artery bypass grafting (CABG). POAF is associated with short- and long-term mortality. METHODS: To identify the true incidence and time course of recurrent atrial fibrillation (AF) in patients with POAF, we prospectively assigned 23 patients with POAF to receive an implantable loop recorder (ILR; Medtronic Inc., Minneapolis, MN, USA) for the detection of recurrent AF...

BACKGROUND: Crack cocaine use is known to contribute to poor adherence to antiretroviral medications; however, little is known about facilitators of or barriers to effective HIV treatment use among HIV-infected crack cocaine users. We sought to identify correlates of optimal pharmacy refill adherence for antiretroviral medications and plasma HIV RNA viral load (pVL) suppression among this population. METHODS: Data from a prospective cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, were linked to comprehensive HIV clinical monitoring and pharmacy dispensation records...

BACKGROUND: Hybrid coronary revascularization (HCR) combines minimally invasive surgical coronary artery bypass grafting of the left anterior descending artery with percutaneous coronary intervention (PCI) of non-left anterior descending vessels. HCR is increasingly used to treat multivessel coronary artery disease that includes stenoses in the proximal left anterior descending artery and at least 1 other vessel, but its effectiveness has not been rigorously evaluated. OBJECTIVES: This National Institutes of Health-funded, multicenter, observational study was conducted to explore the characteristics and outcomes of patients undergoing clinically indicated HCR and multivessel PCI for hybrid-eligible coronary artery disease, to inform the design of a confirmatory comparative effectiveness trial...

Uveal melanoma is a rare subtype of melanoma, accounting for only 3-5% of all melanoma cases in the USA. Although fewer than 4% of uveal melanoma patients present with metastasis at diagnosis, approximately half will develop metastasis, more than 90% of which disseminate to the liver. Infrequently, a number of malignancies can lead to leptomeningeal metastases, a devastating and terminal complication. In this case report, we present an exceedingly rare case of a patient with uveal melanoma who developed leptomeningeal carcinomatosis as the sole site of metastasis...

BACKGROUND: In a trial comparing coronary-artery bypass grafting (CABG) alone with CABG plus mitral-valve repair in patients with moderate ischemic mitral regurgitation, we found no significant difference in the left ventricular end-systolic volume index (LVESVI) or survival after 1 year. Concomitant mitral-valve repair was associated with a reduced prevalence of moderate or severe mitral regurgitation, but patients had more adverse events. We now report 2-year outcomes. METHODS: We randomly assigned 301 patients to undergo either CABG alone or the combined procedure...

OBJECTIVE: Hybrid coronary revascularization (HCR) combines minimally invasive left internal mammary artery (LIMA)-left anterior descending artery (LAD) bypass with percutaneous intervention of non-LAD vessels. The purpose of this study was to compare outcomes of HCR to conventional coronary artery bypass graft (CABG) surgery with single internal mammary artery (SIMA) or bilateral internal mammary artery (BIMA) grafting. METHODS: Between October 2003 and September 2013, 306 consecutive patients who underwent HCR were compared with 8254 patients who underwent CABG with SIMA (7381; 89...

OBJECTIVE: We sought to estimate the reduction in deaths and the number of additional person-years of life that could potentially be gained by nationwide adoption of routine multiple arterial bypass grafting (MABG). METHODS: Propensity matching on 4883 patients undergoing primary, isolated coronary artery bypass grafting (CABG) using the left internal thoracic artery (LITA) from January 1995 to June 2011, resulted in 1023 matched pairs of LITA-radial artery and LITA-saphenous vein patients...

Coronary artery bypass grafting is the most common cardiac surgery operation performed worldwide. It is the most effective revascularization method for several categories of patients affected by coronary artery disease. Although coronary artery bypass grafting has been performed for more than 40 years, no detailed guidelines on the choice of coronary artery bypass grafting conduits have been published and the choice of the revascularization strategy remains more a matter of art than of science. Moreover, there is a clear contradiction between the proven benefits of arterial grafting and its very limited use in everyday clinical practice...

OBJECTIVE: At this consensus conference, we developed evidence-informed consensus statements and recommendations on the practice of off-pump coronary artery bypass graft (OPCAB) by systematically reviewing and performing meta-analysis of the randomized controlled trials (RCTs) comparing OPCAB and conventional coronary artery bypass (CCAB). METHODS: All RCTs of OPCAB versus CCAB through April 2013 were screened, and 102 relevant RCTs (19,101 patients) were included in a systematic review and meta-analysis (15 RCTs of 9551 high-risk patients; and 87 RCTs of 9550 low-risk patients) in accordance with the Cochrane Collaboration and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology...

OBJECTIVE: The optimal level of glycemic control needed to improve outcomes in cardiac surgery patients remains controversial. RESEARCH DESIGN AND METHODS: We randomized patients with diabetes (n = 152) and without diabetes (n = 150) with hyperglycemia to an intensive glucose target of 100-140 mg/dL (n = 151) or to a conservative target of 141-180 mg/dL (n = 151) after coronary artery bypass surgery (CABG) surgery. After the intensive care unit (ICU), patients received a single treatment regimen in the hospital and 90 days postdischarge...

BACKGROUND: Circulating tumor cells (CTCs) are an important diagnostic tool for understanding the metastatic process and the development of cancer. METHODS: This review covers the background, relevance, and potential limitations of CTCs as a measurement of cancer progression and how information derived from CTCs may affect treatment efficacy. It also highlights the difficulties of characterizing these rare cells due to the limited cell surface molecules unique to CTCs and each particular type of cancer...

The aim of this study was to retrospectively investigate whether performing surgical atrial fibrillation (AF) ablation in conjunction with cardiac surgery (CS) increases the risk for postoperative permanent pacemaker (PPM) requirement. The 30-day risk for PPM requirement was analyzed in consecutive patients who underwent CS from January 2007 to August 27, 2013. Patients were divided into 3 groups: (1) those who underwent AF ablation concomitant with CS (AF ABL), (2) patients with any history of AF who underwent surgery who did not undergo ablation (AF NO ABL), and (3) those with no histories of AF who underwent surgery (NO AF)...

BACKGROUND: Among patients undergoing mitral-valve surgery, 30 to 50% present with atrial fibrillation, which is associated with reduced survival and increased risk of stroke. Surgical ablation of atrial fibrillation has been widely adopted, but evidence regarding its safety and effectiveness is limited. METHODS: We randomly assigned 260 patients with persistent or long-standing persistent atrial fibrillation who required mitral-valve surgery to undergo either surgical ablation (ablation group) or no ablation (control group) during the mitral-valve operation...
