Interventional treatment is necessary for fatal drug-refractory tachyarrhythmias. Thirty-three, 33 and 16 patients (pts) with intractable ventricular tachycardia (VT) and/or fibrillation (VF) were managed with cryosurgery (CS), electrical catheter ablation (EA) and implantable pacer-cardioverter-defibrillator (PCD), respectively. Seventy-six and 43 pts with sudden death risk in the Wolff-Parkinson-White syndrome (WPW) also underwent CS and EA, respectively. CS success rates were 85% in VT/VF and 95% in WPW. Those of EA were 48% and 81%, respectively. EA success rates were 100% (6/6) in idiopathic verapamil-sensitive VT originated from LV, 0% (0/2) in VT following
TOF
repair and 0% (0/2) in idiopathic VT originated from right ventricular outflow tract. A new VT developed in 5 of 11 pts with arrhythmogenic right ventricular dysplasia (ARVD) following EA. PCD was effective for prevention from sudden death in idiopathic VF and pleomorphic VT. All of pharmacologic, EA and CS therapies were relatively effective in ischemic heart disease without low EF. In conclusion, the decision of VT-VF therapy may be affected by the underlying
heart disease
and EA may be established as an initial intervention for high risk WPW.

A two-dimensional echocardiographic method was applied to determine the axis of interventricular septum (IVS) in the horizontal plane. This study comprised 19 subjects with ASD, 15 subjects with VSD(I), 20 subjects with VSD(II), 13 subjects with PDA, 16 subjects with PS, 15 subjects with
TOF
and 99 normal children. Parasternal left ventricular short axis view was taken, and the IVS was recorded by using the polaroid prints. The axis of the IVS in the horizontal plane was measured from the recorded polaroid prints. The value of the angularity of IVS (IVS-A) expressed as means +/- one standard deviation (mean +/- 1S.D.) is 52.0 +/- 13.7 degrees in ASD, 42.2 +/- 9.7 degrees in VSD(I), 43.7 +/- 9.1 degrees in VSD(II), 41.6 +/- 11.4 degrees in PDA, 38.6 +/- 10.9 degrees in PS, 61.0 +/- 8.5 degrees in
TOF
and 40.1 +/- 8.2 degrees in normal controls. There was no significant difference among VSD(I), VSD(II), PDA, PS and normal controls but a highly significant difference was noted in ASD and
TOF
as compared to other groups. The correlation coefficient of the IVS-A with (1) the Qp/Qs ratio, (2) the magnitude of shunt (%), (3) the right ventricular pressure and (4) the hematocrits were evaluated among the patient groups. The IVS-A of ASD and VSD(II) had a good correlation with the shunt flow (r = 0.921 and 0.88 respectively) and/or the Qp/Qs ratio (r = 0.782 and 0.955 respectively); while that of VSD(I), PDA, and PS had a good correlation with the right ventricular pressure (r = 0.956, 0.953, 0.842 respectively) and that of
TOF
was mostly concerned with the hematocrits (r = 0.911). Besides, the IVS-A in each severe CHD subgroup was significantly (p less than 0.005 or a better value) higher than the normal control group. Thus an alternative method was validated for evaluating the severity of congenital
heart disease
by using a noninvasive two-dimensional echocardiographic technique.

Real-time two-dimensional Doppler echocardiography (2-D Doppler) is established as an effective diagnostic tool for cardiovascular diseases. However, in determining indications for surgery of congenital
heart disease
(CHD), the possibility of avoiding preoperative cardiac catheterization including radiographic angiography, has not been fully discussed since the clinical introduction of 2-D Doppler. We evaluated 278 patients with CHD by 2-D Doppler including ASDs (75 patients), VSD (76 patients),
TOF
(23 patients), TGA (12 patients), PDA (23 patients), ECD (13 patients), and 60 miscellaneous types of CHD during 27 months. The diagnosis of the 278 patients were confirmed by catheterization and/or surgery. Of these, 114 patients underwent corrective surgery (83 patients) or palliative procedures (31 patients). Preoperative cardiac catheterization was performed for 88 patients (Group A), and omitted in 26 patients (Group B). The 2-D Doppler diagnosis was correct in 79 patients of Group A (89.8%) and in 26 patients of Group B (100%). The surgical procedures scheduled according to the preoperative 2-D Doppler diagnosis were performed for these 105 patients (92.7%) without any corrections by cardiac catheterization diagnosis or by surgical findings. However, 2-D Doppler failed to establish the preoperative diagnosis for six patients in Group A (two patients with ASD, three with PDA, and one with
TOF
) and failed to detect associated cardiac abnormalities for three patients in Group A (two with PAPVC, one with Azygos connection). Results of this study suggest that preoperative cardiac catheterization could be omitted in a maximum of about 90% of surgical candidates with CHD. However, to omit cardiac catheterization 2-D Doppler echocardiographic criteria for indications for surgery in each group of CHD must be established, and any associated coronary artery abnormalities must be ruled out.

The incidence of arrhythmias in 3614 preoperative patients with congenital
heart disease
was 1.6 per cent. Pre- and postoperative serial ECGs in 186 patients with an isolated VSD and in 58 patients with
TOF
were reviewed. The incidence of CRBBB and CRBBB-LAH following VSD repair was 33% and 6.6%, respectively, and for
TOF
was 55% and 5.2%, respectively. Complete A-V block (CAVB) was seen in 2 patients following VSD repair, and none of
TOF
patients developed CAVB. Late cardiac or dysrrhythmic death was not recognized in our limited follow up period. The indications for surgery in membranous VSD should be determined more carefully, because the risk of the surgical damage to the conduction system is still higher. Moreover, we must keep in mind that damage to the A-V conduction system may occur naturally even in a patient with small VSD. Finally, it can never be overemphasized that physicians must pay attention to the occurrence and course of postoperative arrhythmias.

A total of 38 patients aged under 3 months with congenital
heart disease
(CHD) underwent palliative surgery between April, 1988 and March, 1993. The mean age at operation was 28.0 (range 1 to 87) days. Palliative procedures were: pulmonary artery banding (PAB) in 14 patients (IAA complex: 4, CoA complex: 6, AVSD: 2, TA: 2), Blalock-Taussig shunt (BTS) in 12 (
TOF
: 2, TGA: 1, AVSD: 1, PA-IVS: 3, PA-VSD: 3, PA-SV: 1, PA-AVSD: 1), Brock operation in 6 (PPS: 2, PA-IVS: 3, PA-SV: 1), Blalock-Hanlon operation (BH) with PAB in 2 (MA-SV: 2) and Norwood operation (NRD) in 4 (HLHS: 4). PAB of IAA or CoA complex was performed just after the repair of IAA or CoA. Overall operative mortality was 23% (PAB: 14.3, BTS: 8.3, Brock: 33.3, NRD: 100%). One week after PAB, pulmonary artery pressure (PAP) decreased significantly compared to the intraoperative PAP value after PAB (43.1 +/- 16.2, 32.3 +/- 9.0 mmHg, p < 0.05, respectively). Pulmonary artery index (PAI), which is an index of pulmonary artery growth, after BTS increased significantly compared to the preoperative value (mean follow-up interval: 22.1 months) (379.5 +/- 101.4, 159.3 +/- 51.2, p < 0.001, respectively). During Brock operation, balloon catheter was used in order to dilate pulmonary valve. One year after Brock operation, mean pressure gradient through the pulmonary valve 22.6 mmHg. Two-staged corrections of CHD will be performed both safely and successfully by effective palliations at the first stages in early infancy.

The authors investigated a group of 95 pregnant women with congenital
heart disease
. In two induced abortion was indicated fur cardiac reason (major left-to-right shunt in ASD II and in a patient with a non-corrected
TOF
with a significant right-to-left shunt). In the remainder the course of pregnancy was not complicated. From the total number of 132 deliveries only six were by Caesarean section, five times on obstetric grounds. One infant died, delivery during the 29th week by Caesarean section on account of premature escape of amniotic fluid--mother with a history of radial correction of
TOF
. Other relevant data are summarized in a table. In the conclusion the authors summarize basic provisions indicated in pregnant women with congenital
heart disease
.

It has been suggested that plasma sulfoconjugated dopamine (DA) may serve as a source or reservoir for free DA in plasma. Moreover, it has also been reported that the plasma levels of conjugated DA may be used as an index predicting heart failure in patients with
heart disease
. Therefore, in the present study, we have measured the plasma levels of free and sulfoconjugated DA in patients with congenital
heart disease
who underwent total corrective operations. The patients were divided into two groups with (6 patients with tetralogy of Fallot,
TOF
) or without (5 patients with ventricular septal defect without pulmonary hypertension, VSD) cyanosis (mean age of 2.11 years). Blood samples were collected before and after operation from the patients, and plasma free and sulfoconjugated DA levels were measured using high performance liquid chromatography. Preoperative levels of free DA in patients in both groups were higher than the level in age matched control subjects. The plasma level of conjugated DA in
TOF
was higher than that in the controls and was the highest in VSD before operation. DA infusion early after operation caused a rise in plasma free and conjugated DA, however, the levels of increased free DA were lower in the VSD than in the
TOF
group. After discontinuing DA infusion, the plasma levels of free DA remained higher, while those of conjugated DA decreased to a level lower than the preoperative values in both groups. As the plasma levels of free and sulfoconjugated DA vary with hemodynamics, it was assumed that the difference in the plasma sulfoconjugated DA level between the groups before operation was due to the influence of pulminary blood flow on catecholamine homeostasis. Since the decrease in conjugated DA has been postulated to be an index of sustained heart failure, it is conceivable that it takes a long time for patients who underwent cardiac operations in infancy to recover from heart failure.

Between August 1995 and July 1999, we have experienced 14 donors for allografts (mean age: 39.8 +/- 15.8, M/F = 10/4, mean warm ischemic time: 359 minutes). Donated tissues were included 12 aortic valves and 12 pulmonary valves, respectively. Since February 1994, clinical diagnoses of 14 patients included 7 congenital
heart disease
, 5 infective
heart disease
, 1 artificial graft infection, and 1 thrombosed valve. There was no graft-transmitted disease. In congenital
heart disease
, 3 patients (HLHS: 1, Truncus: 1,
TOF
+ PA: 1) died (early mortality, 42%) and 1 with TGA had residual conduit stenosis. However, in infective
heart disease
, all patients survived without recurrent infection and did not need reoperation (early mortality, 0%). Our clinical results of homograft implantation for infective
heart disease
were excellent, but more careful consideration will be needed for congenital
heart disease
in neonates and/or patients with poor preoperative condition.

Heart disease
is the leading cause of mortality and morbidity in the world. As such, biomarkers are needed for the diagnosis, prognosis, therapeutic monitoring and risk stratification of acute injury (acute myocardial infarction (AMI)) and chronic disease (heart failure). The procedure for biomarker development involves the discovery, validation, and translation into clinical practice of a panel of candidate proteins to monitor risk of
heart disease
. Two types of biomarkers are possible; heart-specific and cardiovascular pulmonary system monitoring markers. Here we review the use of MS in the process of cardiac biomarker discovery and validation by proteomic analysis of cardiac myocytes/tissue or serum/plasma. An example of the use of MS in biomarker discovery is given in which the albumin binding protein sub-proteome was examined using MALDI-
TOF
MS/MS. Additionally, an example of MS in protein validation is given using affinity surface enhanced laser desorption ionization (SELDI) to monitor the disease-induced post-translational modification and the ternary status of myocyte-originating protein, cardiac troponin I in serum.

Tetralogy of Fallot with absent pulmonary valve (
TOF
/APV) is a rare form of congenital
heart disease
with a high risk of perinatal mortality, particularly when diagnosed before birth. We aimed to assess whether global left and right ventricular function in fetal
TOF
/APV, using the Tei index, correlate with outcome. We reviewed the fetal echocardiogram and clinical outcome of eight fetuses diagnosed with
TOF
/APV. Of the eight cases, four developed cardiovascular compromise, leading to intrauterine death in two fetuses and neonatal demise in two fetuses, and four fetuses survived the neonatal period. The right ventricular (RV) Tei index was significantly greater and the left ventricular (LV) Tei index tended to be greater in nonsurvivors compared with survivors with
TOF
/APV (RV Tei, 0.90 +/- 0.17 versus 0.30 +/- 0.28, p < 0.05; LV Tei, 0.97 +/- 0.42 versus 0.54 +/- 0.21). The global LV and RV function can be affected in
TOF
/APV. Furthermore, more severe pulmonary insufficiency and worse biventricular function as assessed by Tei index likely contribute to the high perinatal mortality associated with this disease.
