The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

The first description of the flow-directed pulmonary artery catheter (PAC) was published in the 1970s by Jeremy Swan and William Ganz. Ever since its clinical debut, many controversies surrounded the use of the PAC. Regardless of these controversies, the most fundamental issues surrounding this hemodynamic monitoring device remain unresolved, including the exact indications, contraindications, identification of patients who potentially benefit from this technology, and the way we interpret and use PAC-derived parameters...

Swan-Ganz catheter entrapment in the heart, vena cava, or pulmonary artery is rare but may lead to life-threatening events. We report a case of severe tricuspid regurgitation resulting from papillary muscle rupture during percutaneous removal of a Swan-Ganz catheter (SCG) caught by a surgical suture. We performed urgent tricuspid valve repair by suturing the ruptured papillary muscle. This report highlights preventive measures to avoid suture-related entrapment and raises a word of caution regarding percutaneous removal of accidentally entrapped SCGs...

BACKGROUND: Introduced in 1970, the Swan-Ganz catheter (SGC) soon became widely used because of its unique usefulness in managing intensive care patients. Unfortunately, SGC usage was complicated by pulmonary artery rupture (PAR) with a 50% mortality rate that led to a near banning of the SCG in the late 1980s. Increasing knowledge and decreasing incidence of SGC-related PARs (SGPARs) led to the current feeling that the present SGPAR incidence is now low enough to tolerate given the lives saved by SGC usage...

Chronic kidney disease(CKD) is an important risk factor of open heart surgery. In addition, worsening of kidney function after the surgery leads to poor prognosis long-term. It is therefore crucial to protect the kidney function by intensive perioperative management in open heart surgery. In the patients having stage 3-4 CKD, mean arterial pressure needs to be higher than 70 mmHg and cardiac index needs to be greater than 2.4 intraoperatively and postoperatively. Continuous right heart monitoring by Swan-Ganz catheter is useful for this purpose...

Functional tricuspid regurgitation (TR) is a serious pathology to be noted for severe right heart failure (HF) and poor prognosis; however, the conventional assessment of TR has some limitations and the optimal timing of surgical intervention remains unclear. A 79-year-old Japanese female was admitted to our hospital to undergo cardiac surgery, because edema gradually got worse despite the increase in diuretics. She had a history of atrial fibrillation (AF) and chronic HF due to severe TR and had been treated with a furosemide for leg edema 4 years ago...

Pulmonary hypertension (PH) falls into 5 groups, as defined by the World Health Organization. Swan-Ganz catheters determine precapillary versus postcapillary PH. The hemodynamic values of PH at rest and with vasodilatory challenge categorize the etiology of PH and guide treatment. RV maladaptations to increased pulmonary vascular resistance (PVR) and the chronicity of the right ventricle's (RV) response to increased PH and/or increased PVR can be understood with pressure-volume (PV) loops constructed with use of conductance catheters...

Acute massive pulmonary embolism (PE) is associated with high fatality, and catheter-directed thrombolytic therapy has been shown to be an efficacious treatment for this condition. We herein report a patient who developed acute massive PE but could not undergo the conventional catheter-directed thrombolytic therapy. A Swan-Ganz pulmonary artery catheter was placed at bedside to initiate immediate thrombolytic infusion, which resulted in dramatic clinical improvement. This report underscores a potential role of thrombolytic therapy via a transjugular pulmonary artery catheter in patients with acute massive PE who could not undergo the conventional catheter-based thrombolytic intervention...

A 46-year-old man underwent redo bilateral sequential lung transplantation for rapidly progressive bronchiolitis obliterans syndrome that developed 3.5 years after initial transplantation. In the operating room, he was sedated and intubated with a dual lumen endotracheal tube with subsequent single right-lung ventilation and left allograft implantation. His pulmonary arterial pressure became elevated with reperfusion of the newly implanted left lung, which required initiation of cardiopulmonary bypass to facilitate implantation of the right lung...

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...

Peritoneal dialysis (PD) is limited mainly by a higher technique failure rate as compared to hemodialysis (HD), catheter malfunction being an important reason. Intra- and extra-peritoneal catheter configuration may be associated with mechanical and infectious complications affecting method survival. We report our experience with two extra-peritoneal catheter configurations: the straight and the swan-neck (SN) catheters. A total of 85 consecutive patients, 58 males and 27 females were included in the study. Among them, 26 were diabetics; 52 were treated with automated PD (APD) and 33 with continuous ambulatory PD (CAPD)...
