a single gamma ray. Investigations were done to establish normal values and those in patients who had either rheumatic or congenital heart disease. All left-to-right shunts were confirmed at cardiac catheterization. False negative results were rare but false positive results can occur in the presence of congestive cardiac failure. It is possible to detect left-to-right shunts with a pulmonary t...

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...

BACKGROUND Heart transplantation has become a widely accepted surgical option for end-stage heart failure in Korea since its first success in 1992. We reviewed early postoperative complications and mortality in 239 patients who underwent heart transplantation using bicaval technique in Asan Medical Center. METHODS Between January 1999 and December 2011, a total of 247 patients aged over 17 re...

purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...

Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations....

primary cardiac lymphoma is a rare disease which mainly found in elderly men. it is usually a b-cell non-hodgkin’s lymphoma which primarily located in the heart and may involve the pericardium. the common presentations include massive pericardial effusion and heart failure. clinical diagnosis is often delayed in these patients and prognosis is dismal. we report a case of a 70-year-old man prese...

An understanding of the determinants of cardiac output is essential to both medical specialists in their dealing with heart disease and hypertension, and to surgical specialists who deal with shock states and the maintenance of adequate circulation during surgical procedures. In this program, I'll introduce you to some fundamental yet often misunderstood concepts about the determinants of cardi...

RATIONALE Ebstein anomaly is a common congenital heart disease that may induce severe tricuspid regurgitation and dilation of the "atrialized" portion of the right ventricle. Patients who undergo surgery to correct Ebstein anomaly are at high risk of postoperative right-sided heart failure, yet little is known about what pre-, peri-, or postoperative procedures may help reduce this risk. PATI...

Cardiac complications such as arrhythmia and heart failure are common in Graves disease. Early detection and proper treatment of hyperthyroidism are important because cardiac complications are reported to be reversible if the thyroid function is normalized by medical treatment. We report here a case of cardiac complication of Graves disease that was too late to reverse with medical treatment an...
