Article Synopsis
  • Central venous catheters and TIVADs have significantly improved the treatment of pulmonary infections in cystic fibrosis patients, allowing for better tolerance of aggressive intravenous antibiotics during hospital stays.
  • With advancements in procedures and growing experience, lung transplants are now a common option for many CF patients.
  • The case study discusses the successful management of superior vena cava syndrome in a CF patient during lung transplant surgery, emphasizing strategies to reduce procedural risks.

Background: Isolated native tricuspid valve infective endocarditis remains a challenging disease to treat given the large number of patients with substance use disorder. There is limited data on the optimal treatment strategy and the impact of a multidisciplinary endocarditis program on outcomes for this population.

Objectives: To assess the clinical outcomes associated with management of native tricuspid valve infective endocarditis by a multidisciplinary team.

Article Synopsis
  • The opioid epidemic has led to a rise in drug-use-related native tricuspid valve infective endocarditis (DU-TVIE), which is a complex condition requiring specialized care.
  • There's limited research on the best treatment strategies for DU-TVIE, both medical and surgical, despite many affected patients.
  • This review focuses on existing literature and presents a multi-step treatment approach created by the multidisciplinary endocarditis team at the University of Kentucky.

Although multidisciplinary teams have been shown to decrease in-hospital mortality for patient with infectious endocarditis, most studies have focused on the inpatient role of these teams, and are primarily based at European tertiary care centers. There is limited literature available on the optimal longitudinal care of this patient population. Here we outline our experience developing an interdisciplinary endocarditis program at the University of Kentucky, which cares for patients from their index hospitalization into the outpatient setting, while also coordinating transfers from regional hospitals and offering education to regional providers.

Coronary vasospasm is a known complication after coronary artery bypass grafting surgery but has rarely been described in non-coronary cardiac operations. We report the case of a 51-year-old male with nonischemic cardiomyopathy and paroxysmal atrial fibrillation. He presented with severe mitral and tricuspid regurgitation and was taken for mitral valve replacement, tricuspid valve repair, and Maze procedure.

Introduction: We aimed to review the characteristics and outcomes of left atrial veno-arterial extra corporeal membrane oxygenation (LAVA ECMO) at our institution over a 4-y period from 2017 to 2020.

Methods: Among 227 adult patients who received VA ECMO support from January 2017 to December 2020, we reviewed 33 of these who underwent transseptal cannulation and were converted to LAVA ECMO. The timing of transseptal cannulation, either at initiation of VA ECMO (n = 25) or with a later transseptal cannulation to treat complications of left ventricular (LV) distention while on VA ECMO (n = 8), was reviewed.

Background: Thoracic central venous obstruction (TCVO) presents a challenging scenario for patients requiring central venous access. The inside-out technique for crossing occluded veins has been described; however, to date, case series have reported on a limited number of patients. The purpose of the present study was to evaluate the indications for, efficacy of, and outcomes with the inside-out technique at a single tertiary academic center, with close attention to the severity of TCVO using the Society of Interventional Radiology (SIR) TCVO classification.

Background: Hemodynamic values from right heart catheterization aid diagnosis and clinical decision-making but may not predict outcomes. Mixed venous oxygen saturation percentage and pulmonary capillary wedge pressure relate to cardiac output and congestion, respectively. We theorized that a novel, simple ratio of these measurements could estimate cardiovascular prognosis.

The prevalence of extracorporeal cardiopulmonary resuscitation is increasing worldwide as more health care centers develop the necessary infrastructure, protocols, and technical expertise required to provide mobile extracorporeal life support with short notice. Strict adherence to patient selection guidelines in the setting of out-of-hospital cardiac arrest, as well as in-hospital cardiac arrest, allows for improved survival with neurologically favorable outcomes in a larger patient population. This review discusses the preferred approaches, cannulation techniques, and available support devices ideal for the various clinical situations encountered during the treatment of cardiac arrest and refractory cardiogenic shock.

We present a case report of a patient with a pulmonary embolus placed on venoarterial extracorporeal membrane oxygenation who developed venous cannula migration through an undiagnosed patent foramen ovale causing an ischemic stroke due to a thrombus and requiring thrombectomy and device closure of the atrial defect.

Venoarterial extracorporeal membrane oxygenation (ECMO) is a rescue therapy that can stabilize patients with hemodynamic compromise, with or without respiratory failure, for days or weeks. In cardiology, the main indications for ECMO include cardiac arrest, cardiogenic shock, post-cardiotomy shock, refractory ventricular tachycardia, and acute management of complications of invasive procedures. The fundamental premise underlying ECMO is that it is a bridge-to recovery, to a more durable bridge, to definitive treatment, or to decision.

Pump thrombosis is an established complication of left ventricular assist devices (LVADs). Outflow graft obstruction has been previously described as one cause of LVAD thrombosis. We identified four cases of outflow graft obstruction that were attributed to a commonly applied polytetrafluoroethylene (PTFE) covering of the outflow graft.

The use is reported of the AngioVac system to resolve a case of persistent bacteremia in the setting of MRSA tricuspid valve infective endocarditis. The infection was secondary to intravenous drug use in a patient who had failed multiple antibiotic regimens and was deemed a poor surgical candidate.

Background: Subcutaneous implantable cardioverter defibrillators (S-ICDs) have gained increasing popularity because of certain advantages over transvenous ICDs. However, while conventional ICDs require a single surgical incision to implant, S-ICDS need two or three incisions, making them less appealing.

Objective: This study sought out to investigate the feasibility of using a single-incision technique to implant S-ICDs.

BACKGROUND The persistence of a vein of Marshall (VoM) from the left subclavian vein to the coronary sinus is a rare cardiac anomaly known as a persistent left superior vena cava (PLVC). This anatomical variant is usually asymptomatic but can lead to serious complications during catheterization via the left subclavian or internal jugular vein, as described here. In our case, the patent vein of Marshall directly connected the coronary sinus with the left subclavian vein discovered in a cardiac arrest patient because of pericardial effusion during the insertion of a central venous catheter (CVC).
