Contemporary direct ("fully percutaneous") transaxillary (TAx) large-bore arterial access technique advocates for a 0.018" wire to be passed from femoral arterial access to axillary artery to serve percutaneous bailout options. However, in certain patients, avoiding femoral arterial access entirely may be desired. We describe the merits of a "fully upper extremity" (FUE) bailout approach, as a refinement to previously described direct TAx technique.

Abstract Background Although acute intracranial hemorrhage (ICH) is a rare complication of catheter-directed thrombolysis (CDT), it remains a major concern associated with the use of CDT. The incidence and clinical predictors of developing ICH in the setting of CDT are not known. Methods The National Inpatient Sample database was used to identify all patients with proximal lower extremity or caval deep vein thrombosis (DVT) from January 2005 to December 2013 in the United States. Multivariate lo...

ABSTRACT Objective Outflow venous stenting as an adjunct to catheter directed thrombolysis is performed to prevent recurrent thrombosis and to reduce the risk of post-thrombotic syndrome. Historical data shows that stenting improves outcomes of surgical thrombectomy in patients with iliofemoral deep vein thrombosis (DVT), and recent observational data suggests that stenting improves long-term outcomes of catheter-directed thrombolysis (CDT). However, the impact of stenting during CDT on acute sa...

Abstract Objective The objective of this study was to determine the rate of complications of catheter-directed thrombolysis (CDT) in cancer patients with deep venous thrombosis (DVT) compared with anticoagulation therapy alone. Methods This observational study used the National Inpatient Sample database to screen for any cancer patients who were admitted with a principal discharge diagnosis of proximal lower extremity or caval DVT between January 2005 and December 2013. Patients treated with CDT...

Coronary artery disease is a leading cause of morbidity and mortality in the elderly, and with the aging population, it will remain an important healthcare concern. For patients with complex coronary artery disease, coronary artery bypass graft surgery (CABG) is often considered for

BACKGROUND: The effect of utilizing transapical (TA) access for transcatheter aortic valve replacement (TAVR) on cardiac function has not been well studied. AIMS: The aim of this retrospective study is to determine the direct effects of TA access for TAVR on myocardial function parameters and their correlation with 4-year survival. METHODS: Three hundred and thirty propensity matched patients, who underwent TAVR using Sapien valve (Edwards Lifesciences Corp, Irvine, CA) between February 15, 2012...

Abstract Objective To define mortality associated with isolated tricuspid regurgitation (TR) and identify risk factors associated with decreased survival. Patients and Methods We conducted a retrospective cohort study of residents of southeastern Minnesota with moderate-severe or more severe isolated TR diagnosed between January 1, 2005, and April 15, 2015. Isolated TR was defined as TR in the absence of left-sided heart disease or pulmonary hypertension. Patients with an ejection fraction of le...

Abstract Objectives This study sought to determine whether machine learning can be used to better identify patients at risk for death or congestive heart failure (CHF) rehospitalization after percutaneous coronary intervention (PCI). Background Contemporary risk models for event prediction after PCI have limited predictive ability. Machine learning has the potential to identify complex nonlinear patterns within datasets, improving the predictive power of models. Methods We evaluated 11,709 disti...
