Purpose: To compare the diagnostic value of intravascular ultrasound (IVUS) and cardiac catheterization in children with congenital heart disease (CHD) and severe pulmonary hypertension (PH).

[Methods] 59 patients underwent simultaneous determination of the pulmonary artery wedge pressure by Doppler and left and right cardiac catheterization.

Methods: Thirty consecutive patients with coronary disease underwent transthoracic Doppler echocardiography within 24 hours before cardiac catheterization.

The dynamic monitoring study on heart fatty acid-binding protein during cardiac catheterication in children;

Methods:The myocardial infarction model in swines was established by embolizing coronary artery with cardiac catheter and bone marrow mononuclear cells were transplanted into coronary artery through the cardiac catheter.

Methods:The indices of hemodynamics of the aged with AMI were measured by catheterization, compared with that of the elderly of health controls and with that of the non-aged with AMI.

Methods for treating femoral arteriovenous fistula caused by cardiac catheterization;

The haemostatic closure device is intended for closuring femoral artery puncture site after cardiac catheterization.

Chinical Observation and Nursing Care of Cardiac Catheterization for Severe Congenital Heart Disease in Infants and Children;

Purpose: The study was designed to evaluate the therapeutic efficacy of ultrasound-guided thrombin injection for femoral pseudoaneurysms after cardiac catheterization.

Catheterization analysis of 133 infants with congenital heart disease;
