Left atrial pressure indicates the left ventricular filling pressure in patients who have systolic or diastolic left ventricular dysfunction or valvular heart disease. The use of indirect surrogate methods to determine left atrial pressure has been essential in the modern evaluation and treatment of cardiovascular disease because of the difficulty and inherent risks associated with direct methods (typically the transseptal approach). One method that has been widely used to determine left atrial pressure indirectly is Swan-Ganz catheterization, in which a balloon-flotation technique is applied to measure pulmonary capillary wedge pressure; however, this approach has been associated with several limitations and potential risks...

We have previously reported that pulmonary artery endothelial cells (PAECs) can be harvested from the tips of discarded Swan-Ganz catheters after right heart catheterization (RHC). In this study, we tested the hypothesis that the existence of an antiapoptotic phenotype in PAECs obtained during RHC is a distinctive feature of pulmonary arterial hypertension (PAH; World Health Organization group 1) and might be used to differentiate PAH from other etiologies of pulmonary hypertension. Specifically, we developed a flow cytometry-based measure of Bcl-2 activity, referred to as the normalized endothelial Bcl-2 index (NEBI)...

Few inventions in modern medicine have generated as passionate and extended debate as the pulmonary artery catheter (PAC). Since its introduction in 1970, the PAC remains an indispensable monitor in cardiovascular critical care. Despite attempts to develop less invasive alternatives, the PAC remains unequaled as a single monitoring device capable of measuring physiological derangement in most components of the circulation, in the awake or sedated patient, with real-time feedback on the efficacy of an intervention...

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...

BACKGROUND: This study aimed to assess cardiac and pulmonary pathophysiological responses during cooling and extracorporeal life support (ECLS) rewarming in a porcine model of deep hypothermic cardiac arrest (DHCA). In addition, we evaluated whether providing a lower flow rate of ECLS during the rewarming phase might attenuate cardiopulmonary injuries. METHODS: Twenty pigs were cannulated for ECLS, cooled until DHCA occurred and subjected to 30 min of cardiac arrest...

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: 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...

REVIEW
Stefano Ghio, Sandra Schirinzi, Silvia Pica
The pulmonary circulation is a high-flow/low-pressure system, coupled with a flow generator chamber-the right ventricle-, which is relatively unable to tolerate increases in afterload. A right heart catheterization, using a fluid-filled, balloon-tipped Swan-Ganz catheter allows the measurement of all hemodynamic parameters characterizing the pulmonary circulation: the inflow pressure, an acceptable estimate the outflow pressure, and the pulmonary blood flow. However, the study of the pulmonary circulation as a continuous flow system is an oversimplification and a thorough evaluation of the pulmonary circulation requires a correct understanding of the load that the pulmonary vascular bed imposes on the right ventricle, which includes static and dynamic components...

UNLABELLED: Pulmonary arterial hypertension (PAH) causes right ventricular ischemia, dysfunction, and failure. PAH patients may benefit from antianginal agents based on a shared pathophysiology with left ventricular ischemia. A single-center, randomized, placebo-controlled trial (1∶1) to assess the acute vasoreactivity and safety of ranolazine in PAH was conducted. Plasma samples for pharmacokinetic (PK) studies were drawn during hemodynamic measurements at 0, 60, 90, 120, 240, and 360 minutes from a Swan-Ganz catheter...
