Background: There is a lack of randomized controlled trial (RCT) data comparing outcomes different catheter-based interventions for intermediate-risk pulmonary embolism (PE). Methods: PEERLESS prospective, multicenter, RCT that enrolled 550 PE patients with right ventricular dilatation and additional clinical risk factors 1:1 to treatment large-bore mechanical thrombectomy (LBMT) or catheter-directed thrombolysis (CDT). The primary endpoint was hierarchal win ratio (WR) composite the...

Abstract Right‐sided infective endocarditis is a common entity for which surgical intervention frequently high‐risk. Considering its invasive nature, potential complications, and challenging patient population, less endovascular option desirable. The previous series have demonstrated the feasibility of percutaneous therapy tricuspid valve (TV) vegetation utilizing filter‐based bypass circuit. However, limited availability specialized team, resources, procedural complexity, large bore sheath...

Bloodstream infection (BSI) is a common complication of left ventricular assist device (LVAD) support and particularly difficult to treat. The presentation often variable because altered physiology augmentation cardiac output by the device. We studied LVAD recipients at single institution. Multivariate logistic Cox (with time-varying parameters) regression were implemented. Of 212 patients, 58% experienced infections. Driveline (DLI) affected 31%, with 60% them having deep-tissue...

Background: Current evidence and guidelines in nuclear cardiology support the use of stress-only myocardial perfusion imaging (SO-MPI), without rest imaging, to decrease radiation dose patient. We sought determine downstream utilization cardiac procedures patients undergoing SO-MPI comparison those rest-stress (RS-MPI). Demonstration decreased need for following would increase confidence interpreting cardiologists referring physicians. Methods: retrospectively analyzed database at Allegheny...

Congenital absence of the pericardium is a very rare anomaly which has an incidence 1 in 14000 cases autopsy studies. Defects are either partial or complete with defects having much benign course than defects. Partial associated complications like strangulation herniated cardiac chamber coronary artery stenosis from external compression. Absence left most frequently encountered type defect accounts for 2/3 cases. We herein report case entire extremely subtype Cardiac magnetic resonance images.

In left ventricular assist device (LVAD) recipients, bloodstream infections (BSIs) are associated with significant morbidity and mortality, high rates of seeding, persistent bacteremia, often requiring urgent transplantation. the present study, we sought to identify risk factors for development BSIs their impact on heart transplantation mortality while LVAD support. Patients who underwent continuous flow (CF) implantation at our institution (1/2006–7/2016) were reviewed BSIs. Logistic Cox...
