Swan ganz catheter

INTRODUCTION: Hemodynamic decompensation during catheter ablation occurs due to prolonged procedure time and irrigant delivery directly into the cardiac chambers. Real-time hemodynamic monitoring of patients undergoing catheter ablation procedures may identify patients at risk of decompensation; we set out to assess the feasibility of a novel, real-time, intracardiac pressure monitoring system using a standard irrigated ablation catheter. METHODS: We studied 13 consecutive who underwent pressure measurement of the left atrium (LA) and left ventricle (LV) via transeptal access with a Swan Ganz (SG) catheter followed by two commercially available irrigated ablation catheters...

BACKGROUND: Heart failure (HF) is a common condition with high morbidity and mortality  in  Obstructive Sleep Apnea (OSA), especially in obese patient. The causes of HF are often abnormal conduction pathways, pump filling and/or heart valves. Right heart catheterization using Swan-Ganz catheter remains the gold standard to determine pulmonary hemodynamics, but it is costly and invasive. Herein, we propose a new formula for non-invasive Pulmonary artery wedge pressure (PAWP) measurement using tissue Doppler echocardiography...

Acute pulmonary embolism [PE] in the setting of hemodynamic instability and right ventricular strain is a complex presentation and typically is associated with high mortality rates. Prompt recognition and early intervention are critical to the survival of these patient. In such cases, current guidelines recommend use of systemic thrombolytics, along with as needed cardiopulmonary support. If contraindications are present, mechanical thrombectomy is advised. However, guidelines poorly define the next steps in intervention if mechanical thrombectomy were to fail...

Hyperbilirubinemia is a common gastrointestinal complication seen post-cardiac surgery. Here, we describe a case of a 72-year-old male with a past medical history of chronic obstructive pulmonary disease, chronic kidney disease (CKD), pulmonary hypertension, and valvular heart disease with severe aortic stenosis, severe mitral and tricuspid regurgitations who underwent elective aortic valve replacement (AVR), mitral valve replacement (MVR), and tricuspid valve (TV) repair; in addition, he required left thoracotomy for the repair of pulmonary artery perforation from a Swan-Ganz catheter that resulted in a large left pleural bleed...

BACKGROUND: Heart transplantation in donation after circulatory death (DCD) relies on warm perfusion using either in situ normothermic regional perfusion (NRP) or ex situ normothermic machine perfusion. In this study, we explore an alternative: oxygenated hypothermic machine perfusion (HMP) using a novel clinically applicable perfusion system, which is compared to NRP with static cold storage (SCS). METHODS: In a porcine model, a DCD setting was simulated, followed by either (1) NRP and SCS (2) NRP and HMP with the XVIVO Heart preservation system or (3) direct procurement (DPP) and HMP...

BACKGROUND: The entanglement of multiple central venous catheters is a rare and seriouscomplication. The Swan-Ganz catheter is a responsible for various cases. CASE: A 66-year-old male patient was under general anesthesia for a coronary artery bypassgraft surgery. As he had a pre-existing Perm catheter in the right subclavian vein, a SwanGanz catheter was inserted into the left internal jugular vein. Chest radiograph after catheterplacement revealed that the Perm catheter had migrated to the left brachiocephalic vein...

OBJECTIVES: Patients with hypertrophic cardiomyopathy often have concomitant pulmonary hypertension, which has a negative prognostic effect in patients undergoing myectomy. Our objective was to investigate the effect of myectomy on pulmonary artery pressure obtained via Swan-Ganz catheter and characterize how changes in pulmonary artery systolic pressure may indicate outcomes in these patients. METHODS: We performed a single-center retrospective analysis of 271 patients with recordings of intraoperative pulmonary artery pressures during surgical myectomy...

BACKGROUND: Atrial septal defect (ASD) closure can cause acute pulmonary edema. Before transcatheter closure is performed, temporary balloon occlusion test (BOT) is recommended in patients with left ventricular dysfunction to predict the risk of pulmonary edema. However, the accuracy of BOT has not been verified. This study aimed to compare hemodynamic differences between BOT and transcatheter closure. METHODS: A total of 42 patients with a single ASD over age 18 years who underwent BOT before transcatheter ASD closure between October 2010 and May 2020 were analyzed...

The pulmonary artery catheter (PAC) measures hemodynamic parameters in real time, providing valuable data for the management of the critical patient. Nevertheless, its use is associated with several complications. Knot formation is a rare complication related to PAC insertion. A 51-year-old patient with complicated ethanolic liver cirrhosis underwent orthotopic liver transplantation. Invasive hemodynamic monitoring was performed using a Swan-Ganz pulmonary artery catheter (PAC) inserted through the right internal jugular vein...

Severe pulmonary hypertension and severe tricuspid regurgitation are often considered strict contraindications for orthotopic liver transplantation. A combined approach of tricuspid repair and subsequent liver transplantation could provide a novel approach for patients with severe pulmonary hypertension and tricuspid regurgitation to undergo orthotopic liver transplantation. A 62-year-old male with a history of end-stage renal disease on hemodialysis, cirrhosis, and third-degree atrioventricular heart block status post single lead pacemaker insertion presented for an orthotopic liver transplant...

OBJECTIVE: To evaluate the effects of CO2 pneumoperitoneum on venous hemodynamics and cardiopulmonary function during transperitoneal or retroperitoneal laparoscopic surgery. METHODS: A single institution prospective study. 43 patients with renal cell carcinoma undergoing retroperitoneal (22) or transperitoneal (21) laparoscopic partial nephrectomy were enrolled. Hemodynamic functions were monitored by Swan-Ganz and radial artery catheters. Transesophageal echocardiography was used to measure the diameter and blood flow of the inferior vena cava (IVC)...

Right heart catheterization(RHC) is a technique of inserting a catheter into the right heart and pulmonary artery via a peripheral vein, to evaluate hemodynamics and oxygen dynamics. When Swan-Ganz catheter is used, it is called pulmonary artery catheterization (PAC). PAC plays an important role in the diagnosis and evaluation of pulmonary hypertension (PH), and hemodynamic assessment of critically ill patients. We developed this consensus to improve the overall quality of RHC operation, especially the PAC standardization in the diagnosis and evaluation of PH, thereby to promote the diagnosis and treatment of PH in China...

INTRODUCTION: Recent studies showed significant mortality benefit with right heart catheterization (RHC) use in cardiogenic (CS). The optimal timing of RHC in those patients is unknown owing to the lack of available data. METHODS: The Nationwide Readmission Database 2016-2018 was queried for hospitalizations with CS. We excluded patients presented with cardiac arrest or with a history of ventricular assist devices or heart transplantation. Complex samples multivariable logistic, cox, and linear regression models were used to determine the association between RHC timing in the index admission (<2 days [early RHC] vs ≥ 2 days [late RHC]) and in-hospital outcomes (mortality, acute kidney injury [AKI], mechanical circulatory device use [MCD], index length of stay [LOS], hospital charges), and all-cause 30-day readmissions...

INTRODUCTION: The CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF) investigated safety and efficacy of pulmonary-artery-pressure (PAP)-guided remote patient management (RPM) in New York Heart Association (NYHA) Class III outpatients with at least one hospitalization for heart failure (HFH) during the previous 12 months. This pre-specified subgroup analysis investigated whether RPM effects depended on presence and subtype of pulmonary hypertension (PH). METHODS AND RESULTS: In 106/234 MEMS-HF participants, Swan-Ganz catheter tracings obtained during sensor implant were available for off-line manual analysis jointly performed by two experts...

Objectives: The ratio of pulmonary artery (PA) and ascending aorta (AA) diameters has recently been shown to be a useful indicator for disease severity and predictor of outcome in patients with pulmonary hypertension and heart failure. This study aimed at evaluating the applicability of this ratio for perioperative risk assessment of patients with chronic thromboembolic pulmonary hypertension undergoing pulmonary endarterectomy. Methods: In this retrospective cohort study on 149 patients undergoing pulmonary endarterectomy between 2013 and 2020, the preoperative PA to AA ratio was analyzed on axial computed tomography...

Intraoperative pulmonary artery injury due to Swan Ganz catheterization is a rare but potentially life-threatening injury which demands rapid recognition and treatment. Subsequent pseudoaneurysm formation can occur if not immediately recognized, and percutaneous embolization is a viable option for treatment in most settings. We report a case of a 59-year-old female who underwent coronary artery bypass surgery and suffered an intraoperative Swan Ganz catheter-related injury which led to life threatening hemorrhage with subsequent pulmonary artery pseudoaneurysm formation that was successfully embolized...

Purpose: To develop and evaluate domain-specific and pretrained bidirectional encoder representations from transformers (BERT) models in a transfer learning task on varying training dataset sizes to annotate a larger overall dataset. Materials and Methods: The authors retrospectively reviewed 69 095 anonymized adult chest radiograph reports (reports dated April 2020-March 2021). From the overall cohort, 1004 reports were randomly selected and labeled for the presence or absence of each of the following devices: endotracheal tube (ETT), enterogastric tube (NGT, or Dobhoff tube), central venous catheter (CVC), and Swan-Ganz catheter (SGC)...

While urinary output (UOP) remains the primary endpoint for titration of intravenous fluid resuscitation, it is an insufficient indicator of fluid responsiveness. Although advanced hemodynamic monitoring (including arterial pulse wave analysis (PWA)) is of recent interest, the validity of PWA-derived indices in burn resuscitation extremes has not been established. The goal of this paper is to test the hypothesis that PWA-derived cardiac output (CO) and stroke volume (SV) indices as well as pulse pressure variation (PPV) and systolic pressure variation (SPV) can play a complementary role to UOP in burn resuscitation...

Background: Accurate volume status assessment is crucial for the treatment of acute decompensated heart failure (ADHF). Volume status assessment by physical exam is often inaccurate, necessitating invasive measurement with right heart catheterization (RHC), which carries safety, pragmatic (scheduling, holding anticoagulants, etc.), and financial burdens. Therefore, a reliable, non-invasive, cost-effective alternative is desired. Previously, we developed an ultrasound (US) based technique to measure internal jugular vein (IJV) compliance during RHC which was used for single time point central venous pressure (CVP) predictions...

BACKGROUND: In many animal experiments, it is vital to detect sudden changes in cardiac output (CO). This porcine study compared CO that was measured with a Swan-Ganz pulmonary catheter with the gold standard (which was a transit-time flow probe around the pulmonary artery) during interventions that caused hemodynamic instability. METHODS: In one series, 7 pigs were exposed to sudden changes in CO. In another series, 9 pigs experienced more prolonged changes in CO...
