F OLLOWING the pioneering works of Yamakawa et al. (1953)1 and of Soulie (1954),2 Luisada and Liu (1957) 3 4 described a method of recording intracardiac sound vibrations utilizing the electric signal of a pressure transducer through differentiation and filtration. At about the same time, Lewis et al. (1957)5 used a small barium titanate element at the tip of an intracardiac catheter. More rece...

Controversy exists regarding the timing and technique of total correction of traumatic intracardiac lesions. Five patients with penetrating wounds of the heart received emergency treatment aimed at securing normal haemodynamics. No attempt was made to identify intracardiac lesions at this stage. Cineangiography two months to seven years later showed aorto-right ventricular fistulae in all patie...

The development of new imaging tools helps in better investigation of cardiac structures and function by showing detailed images during interventional procedures. Intracardiac echocardiography plays a pivotal role as an intraoperative real-time imaging tool during invasive cardiac procedures. Initially, this echocardiographic technique was particularly useful when transthoracic image quality wa...

It has been demonstrated that intracardiac phonocardiography provides precise localization of the source of cardiovascular sounds. Can this technic be of practical help in the diagnosis of small or complicated ventricular septal defects? Is a ventricular septal1 defect ever silent? What mechanisiims are responsible for the diastolic mlurmlurs in ventricular septal defect? In an attempt to answe...

Intracardiac thrombosis is an infrequent and fatal complication in patients with an inserted pacemaker. A patient with an inserted pacemaker scheduled for ureter stone removal experienced cardiac arrest and cardiopulmonary resuscitation under general anesthesia. Echocardiography showed multiple intracardiac thrombi. Preoperative diagnostic workup including echocardiography for the detection of ...

Detection, localization, and quantification of intracardiac shunts are an integral* part of the hemodynamic evaluation of patients with congenital heart disease. In most cases, an intracardiac shunt is suspected on the basis of the clinical evaluation of the patient before catheterization. There are several circumstances, however, in which data obtained at catheterization should alert the cardi...

A newborn is described in whom the use of a central venous line was complicated by septicaemia and by intracardiac thrombus formation with tricuspid valve insufficiency and heart failure. Besides antibiotics, treatment consisted of tissue type plasminogen activator (tPA) for three days. This treatment resulted in the disappearance of the thrombus and the tricuspid insufficiency. No adverse effe...

Background Blood flow within the cardiovascular system is driven by pressure differences, where blood accelerates from higher to lower pressure areas. Invasive methods of pressure measurement, which are commonly applied to assessment of diastolic function, may not capture the heterogeneity of regional intracardiac pressure differences. We utilized pressure fields based on time-resolved 3D CMR d...

Cardiac Angiofibroma is an uncommon intracardiac tumor. Thus far, only 4 cases of the rare intracardiac tumor have been reported. The present case-report describes an intracardiac angiofibroma in a 57-year-old healthy female. The patient was incidentally diagnosed with a left ventricle mass during echocardiography. We performed cardiac imaging, surgical excision and histological evaluation of t...
