We aimed to describe the clinical characteristics and outcomes of patients who underwent atherectomy at the time of percutaneous coronary intervention in centers with on-site surgical centers (SCs) versus nonsurgical centers (NSCs). Patients treated with coronary atherectomy between January 1, 2006, to December 31, 2019, from the British Cardiovascular Society Intervention (BCIS) registry were included. Primary outcomes were in-hospital all-cause mortality and major adverse cardiovascular and cerebrovascular events. A total of 20,833 patients were treated with coronary atherectomy, of which 7,983 (38%) were performed at NSC. The proportion of coronary atherectomies performed in NSC increased from 12.5% in 2006 to …

Development Of The Centrifugal Blood Pump For A Hybrid Continuous Flow Pediatric Total Artificial Heart: Model, Make, Measure, Carson S Fox, Thomas Palazzolo, Matthew Hirschhorn, Randy M Stevens, Joseph Rossano, Steven W Day, Vakhtang Tchantchaleishvili, Amy L Throckmorton

Clinically-available blood pumps and total artificial hearts for pediatric patients continue to lag well behind those developed for adults. We are developing a hybrid, continuous-flow, magnetically levitated, pediatric total artificial heart (TAH). The hybrid TAH design integrates both an axial and centrifugal blood pump within a single, compact housing. The centrifugal pump rotates around the separate axial pump domain, and both impellers rotate around a common central axis. Here, we concentrate our development effort on the centrifugal blood pump by performing computational fluid dynamics (CFD) analysis of the blood flow through the pump. We also conducted transient CFD analyses (quasi-steady …

Redo Surgical Mitral Valve Replacement Versus Transcatheter Mitral Valve In Valve From The National Inpatient Sample, Muhammad Zia Khan, Salman Zahid, Muhammad U Khan, Asim Kichloo, Shakeel Jamal, Abdul Mannan Khan Minhas, Waqas Ullah, Yasar Sattar, Sudarshan Balla

Department of Medicine Faculty Papers

Background

Redo mitral valve surgery is required in up to one-third of patients and is associated with significant mortality and morbidity. Valve-in-valve transcatheter mitral valve replacement (ViV TMVR) is less invasive and could be considered in those at prohibitive surgical risk. Studies on comparative outcomes of ViV TMVR and redo surgical mitral valve replacement (SMVR) remain limited. Our study aimed to investigate the real-world outcomes of the above procedures using the National Inpatient Sample database.

Methods and Results

We analyzed National Inpatient Sample data using the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD‐10‐CM) from September 2015 …

Development And Validation Of A Prediction Model For Stroke, Cardiac, And Mortality Risk After Non-Cardiac Surgery., Sang H Woo, Gregary D. Marhefka, Scott W. Cowan, Md, Lily Ackermann, Md

Department of Medicine Faculty Papers

Background: Commonly used cardiovascular risk calculators do not provide risk estimation of stroke, a major postoperative complication with high morbidity and mortality. We developed and validated an accurate cardiovascular risk prediction tool for stroke, major cardiac complications (myocardial infarction or cardiac arrest), and mortality after non-cardiac surgery.

Methods and Results: This retrospective cohort study included 1 165 750 surgical patients over a 4-year period (2007-2010) from the American College of Surgeons National Surgical Quality Improvement Program Database. A predictive model was developed with the following preoperative conditions: age, history of coronary artery disease, history of stroke, emergency surgery, preoperative serum …
