OBJECTIVE To elucidate the relationship between acute volume overload and left atrial phasic function in healthy dogs. ANIMALS 6 healthy Beagles. PROCEDURES Dogs were anesthetized. A Swan-Ganz catheter was placed to measure mean pulmonary capillary wedge pressure (PCWP). Cardiac preload was increased by IV infusion with lactated Ringer solution at 150 mL/kg/h for 90 minutes. Transthoracic echocardiography was performed before (baseline) and at 15, 30, 45, 60, 75, and 90 minutes after volume loading began. At each echocardiographic assessment point, apical 4-chamber images were recorded and analyzed to derive time-left atrial area curves...

OBJECTIVES: The impact of pulmonary artery catheterization (PAC) on survival in patients with cardiogenic shock (CS) is not well established. This study aimed to assess whether Swan-Ganz catheter monitoring is related to short- and long-term mortality in patients with CS. METHODS: One hundred and twenty-nine consecutive patients with a first admission for CS were prospectively enrolled in a single-center registry between December 2005 and May 2009, and were subsequently followed up over 5...

To date, many pharmacological agents used to treat or prevent arrhythmias in open-heart cases create undesired systemic side effects. For example, antiarrhythmic drugs administered intravenously can produce drops in systemic pressure in the already compromised cardiac patient. While performing open-heart procedures, surgeons will often either create a small port or form a pericardial cradle to create suitable fields for operation. This access yields opportunities for target pharmacological delivery (antiarrhythmic or ischemic preconditioning agents) directly to the myocardial tissue without undesired side effects...

Pulmonary artery catheters have been extensively used for hemodynamic assessment over the past several decades. We present a case that highlights the management of a known, but rare and catastrophic complication of pulmonary artery catheter based therapy. An elderly lady with acute decompensated heart failure, severe pulmonary hypertension, and atrial fibrillation on anticoagulation had a pulmonary artery catheter inserted for hemodynamic monitoring. Subsequently, the patient developed acute hemoptysis and damped pulmonary artery pressure waveforms during inflation of the catheter tip balloon...

INTRODUCTION: Totally implantable venous access systems (TIVAS), Swan-Ganz (SG) and central venous catheters (CVC) allow easy and repetitive entry to the central cardiovascular system. Fragments of them may be released inadvertently into the cardiovascular system during their insertion or as a result of mechanical complications encountered during long-term utilization. AIM: To present results of percutaneous retrieval of embolized fragments of central venous devices or knotted SG and review the procedural aspects with a series of detailed angiographies...

INTRODUCTION: The placement of a Swan-Ganz catheter into the pulmonary artery may lead to a number of complications (2-17%). In less than 0.2% of cases Swan-Ganz catheterization results in serious vascular damage - pulmonary artery rupture (PAR). This paper presents two distinct forms of iatrogenic PAR treated endovascularly using different vascular devices. AIM: To evaluate the effectiveness of endovascular treatment and the application of different types of vascular devices in the management of pulmonary artery rupture caused by Swan-Ganz catheterization...

Hypothermia is a severe, unpleasant side effect during general anesthesia. Thus, temperature surveillance is a prerequisite in general anesthesia settings during experimental surgeries. The gold standard to measure the core body temperature (Tcore) is placement of a Swan-Ganz catheter in the pulmonary artery, which is a highly invasive procedure. Therefore, Tcore is commonly examined in the urine bladder and rectum. However, these procedures are known for their inaccuracy and delayed record of temperatures...

PURPOSE: To determine whether a pulse waveform analysis in the optic nerve head (ONH) circulation as determined by laser speckle flowgraphy (LSFG) can provide systemic hemodynamic values - the systemic vascular resistance (SVR) in particular - similar to those obtained by using a Swan-Ganz catheter, which is an invasive method. METHOD: Sixteen consecutive subjects were examined. Hemodynamic monitoring was obtained from right heart catheterization with a Swan-Ganz catheter and coronary angiography without an intracoronary nitroglycerin administration...

Extended catheters with an upper abdominal exit-site (UAE) are reportedly associated with a lower incidence of peritoneal dialysis (PD)-related infections. However, little information about the optimal peritoneal catheter configuration for UAE is available. In this nonrandomized multicenter trial, 147 consecutive cases of a UAE involving either a conventional straight (CS; 80 cases) or extended swan-neck catheter (SN; 67 cases) were analyzed to compare exit-site and tunnel infections (ESTI), peritonitis, and catheter survival...

PURPOSE OF REVIEW: In an attempt to make cardiovascular monitoring less invasive and more effective, transesophageal echocardiography is progressively being used in critically ill patients suffering from hemodynamic instability. This review analyses the capacity of transesophageal echocardiography to fully replace the pulmonary artery catheter in the management of hemodynamic impairment, as transesophageal echocardiography similarly allows for the measurement of central venous pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure, pulmonary vascular resistance, stroke volume and cardiac output, and systemic vascular resistance...

This case study reports the operative management of a 63-year-old male patient following implantation of the HeartMate II (HMII) left ventricular assist device (LVAD), with a non-compliant left ventricle (LV) and a reduced right ventricular (RV) end-diastolic volume. Intraoperatively, the patient had a thin, fragile LV wall with laminated clot; a ventricular septal defect was encountered during removal of the clot. Along with an aortic valve repair, the LV and the septum were reconstructed with multiple bovine pericardium patches, thus, moderately reducing the RV and LV stroke volume...

A 62-year-old woman with idiopathic cardiomyopathy and class IIIB/stage C heart failure sustained right pulmonary artery injury from a Swan-Ganz catheter during a pretransplant work up. Postprocedure, it was noted that the patient's segmental pulmonary artery catheter was wedged for an unclear period of time. The patient developed a small volume of blood-tinged sputum and a chest CT revealed a 1.3 cm pseudoaneurysm in the right middle lobe medial segment pulmonary artery and a small area of haemorrhage. The patient underwent pulmonary artery preserving coil embolisation of the pseudoaneurysm to prevent further right heart strain, given an ejection fraction of 20%, which resolved haemoptysis...

BACKGROUND: Patients with severe pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease (COPD) present a poor outcome. Specific PH treatment could improve the clinical and hemodynamic status of these patients but may worsen arterial blood gases. OBJECTIVES: Our study retrospectively included 28 patients with severe precapillary PH (mean pulmonary arterial pressure >35 mm Hg) associated with mild-to-moderate COPD [forced expiratory volume in 1 s (FEV1) >50% predicted]...
