BACKGROUND: Measurement of blood oxygen saturation (O2 saturation) is of great importance for evaluation of patients with many cardiovascular diseases, but currently there are no established non-invasive methods to measure blood O2 saturation in the heart. While T2-based CMR oximetry methods have been previously described, these approaches rely on technique-specific calibration factors that may not generalize across patient populations and are impractical to obtain in individual patients...

BACKGROUND: Cardiac troponin T (cTnT) is a specific marker of myocardial injury that is elevated in patients with coronary artery disease or heart failure; it has been investigated as a prognostic marker. A highly sensitive, commercially available assay has been developed to detect cardiac troponin T (hs-cTnT). This study aimed to evaluate the clinical implications and prognostic value of hs-cTnT in patients with congenital heart disease (CHD). METHODS: We evaluated 122 consecutive patients hospitalized at our institution because of heart failure or scheduled cardiac catheterization...

INTRODUCTION: Bladder diverticula can be congenital or secondary to benign prostatic hyperplasia with bladder outlet obstruction, and be a source of high postvoid residuals prompting surgical intervention. We sought to evaluate the outcomes of patients with bladder diverticula undergoing holmium laser enucleation of the prostate (HoLEP) for bladder outlet obstruction. METHODS: We retrospectively reviewed HoLEP patients with at least one bladder diverticulum at two high volume institutions...

OBJECTIVE: The present study was designed to evaluate the characteristics of pulmonary hypertension (PH) and adult cardiology practice patterns for PH in our country. METHODS: We evaluated preliminary survey data of 1501 patients with PH (females, 69%; age, 44.8±5.45) from 20 adult cardiology centers (AdCCs). RESULTS: The average experience of AdCCs in diagnosing and treating patients with PH was 8.5±3.7 years. Pulmonary arterial hypertension (PAH) was the most frequent group (69%) followed by group 4 PH (19%), group 3 PH (8%), and combined pre- and post-capillary PH (4%)...

OBJECTIVE: Congenital cardiac malformations with high pulmonary blood flow and pressure due to left-to-right shunts are usually repaired in early infancy for both the benefits of early relief of heart failure and the fear that the concomitant pulmonary hypertension may become irreversible unless these defects are corrected at an early age. Age, however, has been a poor predictor of irreversibility of pulmonary hypertension in our experience, which is presented here. DESIGN: A retrospective observational study...

INTRODUCTION AND OBJECTIVE: Urethral duplication is a rare congenital anomaly, with roughly 200 cases reported in the literature (1). It is more frequent in males, with few cases reported in females. The clinical presentation differs according to the anatomical variant present. The duplication most commonly occurs in the sagittal plane with one urethra located ventrally and the other dorsally (2). Usually the ventral urethra is the more functional of both. Duplications occurring in the coronal plane are quite rare and they are usually associated with bladder duplication (3)...

Ventricular septal defects (VSDs) are among the most common congenital cardiac lesions. Large defects at apicomuscular regions, especially in young patients, are far from accessible to surgeons for conventional surgery. Moreover, the transcatheter closure of VSDs in these patients is difficult and carries a high risk of complications because of the large sheath size relative to the patient's size. The periventricular approach simplifies VSD closure and, thus, eliminates the potential complications of cardiac catheterization and fluoroscopy as it is performed under echocardiographic guidance...

Seong-Ho Kim
During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates...

BACKGROUND: Xenon has repeatedly been demonstrated to have only minimal hemodynamic side effects when compared to other anesthetics. Moreover, in experimental models, xenon was found to be neuroprotective and devoid of developmental neurotoxicity. These properties could render xenon attractive for the anesthesia in neonates and infants with congenital heart disease. However, experience with xenon anesthesia in children is scarce. AIMS: We hypothesized that in children undergoing cardiac catheterization, general anesthesia with a combination of sevoflurane with xenon results in superior hemodynamic stability, compared to sevoflurane alone...
