right atrium is a common practice in paediatric cardiac surgery [3]. The procedure is technically simple, easily performed by any cardiac surgeon with no additional risks beyond those inherent to the thoracic procedure; the complications are mainly related to the general condition of the patient. In paediatric patients, the transthoracic catheter is always used on a temporary basis and removed ...

Using two-dimensional echocardiography, we studied the pathophysiology of intracardiac thrombus regression accompanied by anticoagulant therapy in 82 consecutive patients with acute cardiogenic cerebral embolism. We noted intracardiac thrombus in 15 patients; nine of the 15 were started on anticoagulant therapy with warfarin potassium to maintain the prothrombin time between 2.5 and 3.5 (intern...

The sound-pressure correlates of the second high frequency component of a split first heart sound (S,) were investigated in 27 patients. An external phonocardiogram was recorded with high fidelity sound and pressure from the left and right atria in 21 patients, from the pulmonary artery in 14 of these, and from the central aorta in 11. In the remaining six patients, high fidelity recordings fro...

In the past few years many centres have tended to prefer the pervenous to the transthoracic approach when implanting permanent pacemakers because of the reduced hospital stay and the lower postoperative morbidity. The disadvantages of this approach, however, are an increased failure rate and a greater incidence of late complications associated with the electrode. It may change in position and m...

A 70-year-old man who visited Samsung Medical Center reported experiencing palpitation for 2 weeks. He had undergone excision of a mass in the right buttock due to rhabdomyosarcoma 7 years prior to this visit. Transesophageal echocardiography showed a pedunculated mass in the left ventricle, which was thought to be a vegetation of infective endocarditis, metastasis of the primary tumor, or thro...

SEE PAGE 1036 I t may be surprising to realize that the initial work in intracardiac echocardiography (ICE) imaging appeared in the early 1960s, preceding the development of interventional catheterization procedures (1). The increasingly sophisticated catheter-based structural interventions that have emerged over the past decade, stimulated the growth of ICE to become an established imaging mod...

This paper describes a new method for the detection of sound from within the heart in man. It employs the technic and equipment of underwater listening developed and use(l by the Navy in antisubmarine warfare. Records are shown to illustrate the localization of heart sound production to an extent not possible by phonocardiograms from the chest wall. The technic has proved helpful in the evaluat...
