The present study employed a new right-heart catheterization technique to measure pulmonary arterial pressure, pulmonary arterial wedge pressure, and pulmonary vascular resistance in anesthetized intact-chest, spontaneously breathing mice. Under fluoroscopic guidance, a specially designed catheter was inserted via the right jugular vein and advanced to the main pulmonary artery. Cardiac output ...

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 efficacy of orally administered isosorbide dinitrate (IS) has been questioned. Recently vasodilators have been shown to lower left ventricular filling pressure (LVFP) and raise cardiac output in heart failure. In the present study oral IS was evaluated in 12 patients with high LVFP due to heart failure. After right heart catheterization, patients with LVFP > 14 mm Hg were randomized double-...

Shone's anomaly, a congenital cardiac malformation complex, consists of multiple levels of left heart obstruction. A rare case of an incomplete form of this anomaly discovered incidentally during cardiac catheterization for an unrelated event is described.

BACKGROUND Patterns of care for acute myocardial infarction (AMI) strongly depend on the availability of on-site cardiac catheterization facilities. Although the management found at hospitals without on-site catheterization does not lead to increased mortality, little it known about its impact on resource utilization and non-fatal outcomes. METHODS We identified all patients (n = 35,289) admi...

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 Reverse takotsubo cardiomyopathy is a rare variant of classic takotsubo cardiomyopathy that presents within a different patient profile and with its own hemodynamic considerations. Its recognition is important for prognostic, evaluation and treatment considerations. CASE PRESENTATION Case 1: A 69-year-old Caucasian woman presented with substernal chest pain following a motor vehi...

We present a case who was initially thought to have an acute coronary syndrome but who was later diagnosed to have an apical hypertrophic cardiomyopathy. Interestingly, the diagnosis could be established with left heart catheterization, not echocardiography.

BACKGROUND The aim of this study was to examine the trend in increasing life expectancy in relation to heart attack and cardiac catheterization. METHODS A retrospective study of very elderly patients over 90 years of age (study group) and between 70 and 79 years of age (control group) with myocardial infarction and acute coronary syndrome who underwent coronary angiography was conducted.
