Indicators Of Fontan Circulatory Failure In Pediatric Patients: A Scoping Review Of Early Clinical And Hemodynamic Factors, Marina Mcmahon

Student Works

Structured Summary

a. Background/Introduction:

For patients with single ventricle congenital heart disease, the Fontan procedure is the definitive palliative procedure. Although advancements have been made in the surgical technique and management, the Fontan circulation is inefficient and prone to progressive dysfunction. Elevated central venous pressure, non-pulsatile pulmonary blood flow, and reduced cardiac output can lead to many complications, and eventual failure. These conditions can lead to protein losing enteropathy, plastic bronchitis, and hepatic fibrosis which often indicate advanced decline. Though a known problem, there is a lack of standardized criteria to guide optimal intervention timing of Fontan revision prior to …

Pharmacologic Interventions To Reduce Cardiopulmonary Bypass Induced Inflammation In Cardiac Surgery: A Scoping Review, Wyatt Anderson

Cardiopulmonary bypass (CPB) is essential in cardiac surgery but can trigger a systemic inflammatory response that contributes to postoperative complications. The scoping review conducted has a purpose to map the existing literature on pharmacologic interventions to mitigate CPB related inflammation. While several interventions demonstrated potential anti-inflammatory effects, findings were inconsistent, and no standardized pharmacologic approach is currently agreed upon.

Methods

This scoping review followed PRISMA-ScR guidelines.Both PubMed, and CINAHL were screened for studies published between 2000 and 2024 that evaluated pharmacologic interventions aimed at reducing CPB related inflammation. After screening and duplicate removal, 10 studies met …

Clinical Applications Of Topical Platelet-Rich Plasma In Cardiac Surgery: A Scoping Review, Jaron M. Davis

Student Works

Background: Postoperative wound complications persist as a significant challenge within adult cardiac surgery. Deep and superficial sternal wound infections, along with complications at saphenous vein harvest sites, are linked to increased morbidity, extended hospital stays, and substantial healthcare expenses. Topical platelet-rich plasma (PRP), commonly known as platelet gel, has been suggested as a biologically active adjunct that may facilitate tissue repair and mitigate postoperative complications. While PRP has garnered attention in surgical practice, the overall scope and consistency of the supporting evidence in cardiac surgery remain ambiguous.

Objective: The purpose of this scoping review is to map and describe the …

Impella 5.5 Versus Heartmate 3 In Left Ventricular Unloading, Hannah Frederick, Douglas Tran, Erik Sorenson, H. Todd Massey, Albert Hicks, Manjula Ananthram, Bartley P. Griffith, Aakash Shah

The VAD Journal

The Impella 5.5 (Abiomed) is increasingly used as a bridge to durable left ventricular assist device (LVAD) implantation in advanced heart failure, yet most studies focus on survival and transition success rather than left ventricular (LV) unloading or valvular effects. This study addresses this gap by comparing Impella 5.5 and HeartMate 3 (HM3, Abbott) in terms of unloading and cardiac support at similar flow rates. We conducted a retrospective study of nine patients who received Impella 5.5 before HM3 implantation. The primary outcome was the degree of LV unloading, as assessed by changes in left ventricular end-diastolic diameter (LVEDD). There …

Real-Time Hemodynamic Deterioration Following Polymorphic Ventricular Tachycardia In A Patient With Preexisting Aicd Implanted With Lvad, Dhruvil Patel, Maya Guglin, Deepa Iyer, Chonyang Albert, Jagpreet Grewal, Kenneth Dulnuan

The VAD Journal

Ventricular arrhythmias (VAs) are common in patients with a left ventricular assist device (LVAD), but the literature remains inconclusive regarding the benefits of an automatic implantable cardioverter-defibrillator (AICD) in this population, especially in those with a preexisting device before LVAD implantation. Here, we report the acute hemodynamic consequences of polymorphic ventricular tachycardia in a patient with a preexisting biventricular AICD who was implanted with an LVAD (HeartMate 3). This case underscores the importance of considering AICD placement on a case-by-case basis and highlights the need for a well-designed study to establish its benefit in this population.

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 …

Aortoduodenal Syndrome: A Rare Case Of Duodenal Obstruction Due To Endovascular Aneurysm Endoleak., Raksha Adhikari, Parth Patel, Christopher Tait

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Aortoduodenal syndrome results from expansion of an abdominal aortic aneurysm, leading to symptoms of upper gastrointestinal obstruction. Endovascular aneurysm repair of large or symptomatic aortic aneurysms has become an important treatment modality for patients with abdominal aortic aneurysm. However, a large proportion of these grafts are complicated by endoleaks that can lead to a spectrum of significant symptoms. We present a case of rapidly worsening gastrointestinal obstructive symptoms in a patient with an already repaired aortic stent graft and a solitary kidney, found to be due to a type III endoleak that improved after emergent repeat endovascular aneurysm repair.

Percutaneous Closure Of A Left Ventricular Pseudoaneurysm Using A Post-Infarct Vsd Device Guided By Intracardiac Echocardiography, Omar Jafar, Nicholas Valle, Rupinder Bahniwal, Matthew Summers

Department of Medicine Faculty Publications

Left ventricular pseudoaneurysm (LVPA) is a rare, life-threatening complication that may arise after cardiac surgery, myocardial infarctions, or infective endocarditis. We present a case of a 55-year-old woman with complex surgical history and prior infective endocarditis who developed an incidental LVPA. Due to lack of surgical repair options, a percutaneous approach was pursued using a post-infarct ventricular septal defect device (PIVSD) under guidance of fluoroscopy and intracardiac echocardiography (ICE) guidance with successful exclusion of LVPA. This case highlights the utility of multimodal imaging in the percutaneous management of complex left ventricular lesions.
