A study on 48 patients with intracardiac myxoma (male:18, female:30; ages of 8-67) in Viet duc Hospital during 1989-2000 has shown that myxoma in the left atria, right atria, left ventricle and right ventricle were 41; 5;1 and 1, respectively. The myxoma in the left atria involved breathing difficulty, faint, palpitation, the ultrasound helped diagnosing and indicating an operation as well as monitoring postoperation without other tests or cardiac X-ray. The operation was an unique treatment as soon as possible, only after diagnosis. The long-term outcome of operation was good.

The left ventricle is realized as the cardiac structure of greatest importance for cardiac pump function, and the role of the right ventricle has been overlooked. However, the right ventricle and the left ventricle are in series and physiologically coupled so that a disturbance in the one ventricular function will influence the behavior of the other. Thus, there ia growing interest in the importance of the right side of the heart, particularly in patients undergoing cardiac surgery. Moreover recently, right ventricular failure has been identified as a cause of progressive deterioration in patients undergoing cardiac operations, and it may limit the overall success of the procedure. This study was performed to investigate right ventricular ejection fraction of the cardiac patients at pre and post-perfusion period. 10 cases were measured and analyzed. The results were as follows: I) There were no singificant differences statistically in demographic data of the patients. 2) Pulmonary capillary wedge pressure(PCWP) of postperfusion 10 min. was significantly increased compared to preperfusion period(p<0.01). 3) Systemic vascular resistance(SVR) of immediate postperfusion period was significantly decreased compared to preperfusion period. 4) Heart rate and central venous pressure(CVP) of postperfusion period were statistically significantly increased, but clinically no significant change compared to preperfusion period. 5) Cardiac output(CO) and right ventricular ejection fraction(RVEF) of postperfusion period were no significant change compared to preperfusion period.

BACKGROUND AND OBJECTIVES: We checked traditional and high-level precordial electrocardiogram (ECG) leads in patients who had undergone right ventricular outlet obstruction (RVOT) reconstruction surgery and evaluated the effect of ECG lead position on their QRS duration. SUBJECTS AND METHODS: We enrolled 34 patients who had undergone surgery for congenital heart disease with RVOT obstruction and who had received followed up care that included recorded ECG at a pediatric cardiac out-patient clinic. The control group included 29 patients who did not have hemodynamically significant intracardiac abnormality. We recorded traditional standard 12-leads ECG from the 4th intercostals space, and moved the precordial leads to the 3rd and 2nd intercostals spaces, and recorded ECGs repeatedly. RESULTS: In all groups, there was no significant difference of mean QRS duration and QTc interval between traditional standard 12-leads ECGs and ECGs at higher intercostals spaces. There was no significant difference of ECG parameters between groups. In the control group, the degree of the change between the 4th intercostals space (ICS) QRS and 3rd ICS QRS was significant (p=0.031), and although, it was insignificant, ECGs at the 3rd ICS showed decreased QRS duration in group 1 (V1: 3rd ICS 119.21+/-21.53 msec vs. 4th ICS 122.80+/-31.78 msec. V2: 3rd ICS 113.68+/-19.43 msec vs. 4th ICS 118.24+/-19.16 msec). CONCLUSION: Although the positional change of ECG leads did not result in a significant effect on measuring QRS duration after surgery, ECG leads at the 3rd ICS rather than at the 4th ICS may cause alteration of ECG readings. Therefore, we suggest that ECGs should be recorded in as accurate a position as possible.

OBJECTIVETo compare the postoperative outcomes of patients with the diagnostic univentricular heart undergoing lateral tunnel (LT) operation with extracardiac conduit (EC) operation.

METHODSFrom June 1996 to July 2007, 114 consecutive patients with a single ventricle underwent total cavopulmonary connection (TCPC) in Children's Heart Center, University Hospital Giessen and Marburg GmbH, Germany. A LT was performed in 19 (16.7%) patients, and an EC in 95 (83.3%) patients. The mean age of EC group was 50.8 +/- 31.6 (ranging from 22 to 212) months, and that of LT group was 61.5 +/- 41.2 (ranging from 30 to 168) months. Early and midterm outcomes of two groups were analyzed.

RESULTSOne died in LT group (5.3%) and three in EC group (3.2%). The overall mortality was 3.5%. There was no significant difference in mortality between EC and LT groups (P>0.05). The postoperative pulmonary arterial pressure, oxygen saturation, and effusion time of two groups had no significant difference (all P>0.05). No significant difference in the occurrences of complications (arrhythmias, enteropathy, and thrombosis) was found between two groups after operation (P>0.05).

CONCLUSIONSThere seems no difference between LT and EC in the clinical results in the early and middle postoperative stage. Glenn anastomosis followed by an EC seems to have some advantages.

OBJECTIVETo investigate the histopathological features of primary restrictive cardiomyopathy (PRCM).

METHODSNine extransplanted hearts from heart transplantation recipients were examined. Gross and histopathological findings were observed, photographed and final pathological diagnosis was compared to clinical diagnosis. The myocardial ultrastructure changes were determined using transmission electron microscopy.

RESULTSThe hallmark pathologic feature of PRCM was distinguished by myocardial cell degeneration and hyperplastic collagen fibrils around the myocardial cells.Fibrosis was severer in left ventricle free wall than in ventricular septum and right ventricle. The degree of myocardial cell degeneration and poloidal disorder were severer in patients with reduced ejection fraction (EF) than in patients with preserved EF. Transmission electron microscope evidenced severe interstitial fibrosis, myofibrillar changes of sarcomere structure, abnormalities both on intercalated disc number and distribution.

CONCLUSIONSPRCM is characterized by hyperplastic collagen fibrils around the cardiomyocytes. Fibrosis is severer in left ventricle than in right ventricle. Sarcomere dysplasia is the main cause of PRCM, and ultrastructural examination is helpful for PRCM diagnosis.
