Cardiac ventriculography is used to define the anatomy and function of the ventricles and related structures in patients with congenital, valvular, coronary, and myopathic heart disease (1–5). Specifically, left ventriculography may provide valuable information about global and segmental left ventricular function, mitral valvular incompetence, and the presence, location, and severity of a numbe...

The Incidence of superior ORS axis in 200 consecutive infants and children with cyanotic congenital heart disease who underwent cardiac catheterization is 26%. Patients with asplenia syndrome, transposition of great arteries, double outlet right ventricle and dextrocardia complex are most likely to have superior ORS axis. The frequency of superior QRS axis in patients with tetralogy of Fallot i...

Serial assessment of the status of the pulmonary vascular bed requires bed requires cardiac catheterization. We have demonstrated the right ventricular systolic time intervals (RVSTI) may be measured from the pulmonary valve echo. The right ventricular ejection time (RVET) and right pre-ejection period (RPEP) were measured in 45 normal patients. The RVET and RPEP decreased with increasing heart...

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...

In 8 patients with complete heart block, cardiac and hemuodynammic functions were determined by methods based on cardiac catheterization. The data characterize the impairment in these functions in asymptomatic subjects and indicate, in addition, the further changes over the course of several years in the same subject, the deleterious effects associated with congestive heart failure, and the cha...

spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. we report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. electrocardiography showed st elevation in leads v2-v4 and st depression in the inferior leads. lab data were normal. cardiac catheterization showed a suspicious thrombotic les...

Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children...
