Cardiac Step-Down Unit (Csu), Two Failures Drive Suboptimal Vte Prevention: Quality Improvement, Jorim Parmar, Shakir Al-Ezzi, Anvi Manduva, Muhammad Suleman, Fahed Alsayed, Debra Medsker

North Texas GME Research Forum 2026

BACKGROUND: In the Cardiac Step-down Unit (CSU), two failures drive suboptimal VTE prevention: (1). over-ordering of SCDs in patients unlikely to benefit and (2). < 10% documented application when SCDs are truly indicated. Baseline data indicates that curbing over-ordering alone would reduce recorded non-compliance by >50%, revealing a clear opportunity for system redesign.

METHODS: To integrate the updated “3 Bucket” Risk Model assessment into the computerized physician order entry (CPOE) in order to delineate the prophylaxis for a given patient population. Once the manual risk assessment proves to be viable in increasing compliance, we can propose having the tool adopted into the CPOE system. Root Cause Analysis revealed that lack of standardized VTE risk stratification leads to inconsistent ordering practices – …

Percutaneous Closure Of Ventricular Septal Rupture After Myocardial Infarction:, Thomas A. Cook, Simone K. Schumaecker, Anjani Patibandla, Nicholas J. Valle, Matthew R. Summers

Department of Medicine Faculty Publications

BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction is a rare but deadly complication with mortality rates exceeding 90% when left untreated. Coronary ischaemia leads to myocardial necrosis and friability resulting in septal rupture, most commonly 3-5 days post-infarction. The sudden development of a left-to-right shunt causes volume overload in the right ventricle, pulmonary vasculature, and left atrium, precipitating biventricular failure, and cardiogenic shock. Management requires careful consideration of timing and modality of closure along with stabilization with mechanical circulatory support in severe cases.

CASE SUMMARY: A 65-year-old female presented with anterior ST-segment elevation myocardial infarction complicated by VSR …

Introduction: Leadless intracardiac pacemakers (LICPs) reduce lead-related complications but may be malpositioned in patients with unrecognized structural defects. We report a 69-year-old man with high-grade AV block whose LICP, intended for right ventricular placement, was found in the left ventricle via an undiagnosed ostium secundum ASD after presenting with multifocal embolic strokes 16 months later. Case Presentation: Stroke workup for acute right-sided symptoms revealed the LICP in the LV and a large, previously undiagnosed ASD with bidirectional shunting and severe pulmonary hypertension. Embolic infarcts were attributed to either paradoxical embolism or device-related thromboembolism. Due to high surgical risk, …


Serendipitous Supernormality, Behzad B. Pavri, Eitan Frankel May 2025

Serendipitous Supernormality, Behzad B. Pavri, Eitan Frankel

Division of Cardiology Faculty Papers

We describe a patient who underwent AV node modification to create complete heart block in the setting of incessant, ablation-and-drug-refractory, symptomatic atypical atrial flutter. His dual chamber defibrillator (previously implanted for resuscitated cardiac arrest) was programmed to the VVIR mode at a faster pacing rate of 85 bpm. Serendipitously, this rate was an almost exact factorial of his flutter rate of 250-260 bpm. This resulted in every 6th flutter wave falling in the supernormal period, resulting in fixed-coupled supraventricular bigeminy and trigeminy in the setting of complete heart block. Reprogramming the pacing rate to 75 bpm abolished bigeminy and trigeminy.
