SIMILJARITIES between mitral stenosis and left ventricular failure, regarding their effects upon the pulmonary circulation and the right heart, have been known long before cardiac catheterization permitted their direct assessment. The advent of mitral valve surgery, a decade ago, stimulated widespread interest in the hemodynamies of mitral stenosis. On the other hand, circulatory changes associ...

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 accept...

Hemodynamic monitoring has moved in the last few years from being the holy grail of evaluating patients with acute heart failure to being all but extinct. Recent studies have not demonstrated any sustained benefits from right heart catheterization, and some studies have even suggested harm due to adverse events related to this invasive procedure. It is possible that this lack of efficacy is rel...

Introduction: Central Venous Catheterization (CVC) is an invasive procedure used for many reasons in the clinics such as hemodynamic monitoring, fluid and drug administration hemodialysis. It unlikely problem to forget central catheter wire (CW) intravascular area this creates dangerous consequences. Causes inattention, inexperience, time constraints due workload, fatigue absence of accompanime...

A 54-year-old African American male with no medical history presented to an urgent care clinic with signs and symptoms of new-onset congestive heart failure. There was an initial concern for congestive heart failure secondary to an ischemic etiology as an echocardiogram revealed a depressed ejection fraction. However, a left heart cardiac catheterization did not demonstrate any significant coro...

BACKGROUND Non-invasive measures that can accurately estimate cardiac output may help identify volume-responsive patients. This study seeks to compare two non-invasive measures (corrected carotid flow time and carotid blood flow) and their correlations with invasive reference measurements of cardiac output. Consenting adult patients (n = 51) at Massachusetts General Hospital cardiac catheteriza...
