The process of extracting information about a series of cases investigated by cardiac catheterization or of analysing the work of one cardiac centre is very time consuming when this has to be done by hand, whereas data stored in a computer are easily available and may be analysed by complex statistical methods. Such analyses may then point to the need for improvements in methods of investigatio...
The percutaneous femoral vein approach is used routinely for cardiac catheterization in the pediatric age but in some children, it may be impossible as in the case of iliac vein or inferior vena cava thrombosis due to previous cardiac catheterization, or inconvenient as for right ventricular endomyocardial biopsies. In the period between 1982 and 1990, 160 cardiac catheterizations or right vent...
Background and aims: It is essential for cardiologists, technologists, nurses working in the cardiac catheterization laboratory to understand radiation protection. However, protective equipment usage still low, wearing dosimeters also low there little awareness of protection practice.
BACKGROUND Some prior studies have suggested that the time to cardiac surgery after cardiac catheterization is inversely related to postoperative acute kidney injury (AKI). However, these studies, because of the small number of patients, were unable to adequately account for patient case-mix and included both those undergoing elective surgery and those undergoing urgent surgery. METHODS AND R...
BACKGROUND Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free di...
OBJECTIVE To assess the occurrence of cardiac events in patients diagnosed with left main coronary artery disease on diagnostic cardiac catheterization and waiting for myocardial revascularization surgery. METHODS All patients diagnosed with left main coronary artery disease (stenosis > or = 50%) consecutively identified on diagnostic cardiac catheterization during an 8-month period were sele...
The widespread use of cardiac catheterization has revealed certain dangers inherent in the procedure when the catheter is advanced beyond the tricuspid valve. Ventricular and other ectopic rhythms are a well recognized risk, but less is known about the effect of damage to the endocardium produced by the catheter in man (Zimdahl, 1951). This paper presents in detail a case that terminated fatall...
