BACKGROUND: Percutaneous Mitral Valvuloplasty (PMV) is the first-line treatment modality in selected patients with symptomatic mitral stenosis and more recently available Inoue single-balloon catheter technique produces good results with low incidence of complications. The purpose of this study was to evaluate the immediate and over 6 months follow-up results after successful PMV with an Inoue balloon and to identify the predictive factors for the results. METHODS: From May 1995 to Feburary 1997, a PMV with an Inoue balloon was tech-nically successful in 114 (95%) of the 119 patients treated at the Sejong General Hostpital. In this study, a series of echocardiographic follow-up were performed in 54 patients with rheumatic mitral stenosis, at least 6 months after their successful PMV. In PMV, the inflation was conducted in steps, starting with a recommended maximum size of balloon by the Inoue criteria. After each inflation, the mitral valve opening and competence were evaluated by Transesophageal echocardiography (TEE) and continuing increase balloon size. RESULTS: Echocardiographic follow-up assessment was performed in 54 patients serially in a interval of 3 months or 6 months. Their mean age was 46+/-11 years (24 to 66 years) and the mean total echocardiographic score was 7.1+/-1.6. A optimal result was obtained in 95% of the cases (51/54). The post-PMV mitral valve area increased to 1.95+/-0.37 cm 2 and 1.79+/-0.28 cm 2 by 2-D and Doppler method, the average transmitral mean diastolic pressure gradient decreased to 5.16+/-2.8 mmHg and LA pressure was decreased to 11.28+/-8.2 mmHg. The newly developed and aggravated mitral regurgitation was observed in 17 patients (31.5%). The restenosis was noted in 2 cases (3.7%) after 1 year follow-up. The pre-procedural echocardiographic score for leaflet mobility, thickening and calcification was more higher in patients with restenosis. There was significant tendency of decrement in the mitral valve area in patients with a echocardiographic score=8 compared with those< or =8 over 6 months after the PMV. CONCLUSION: PMV with the Inoue balloon under TEE guide as a combined treatment modality of patient with symptomatic mitral stenosis is relatively safe and achieves good immediate and midterm follow-up results. The echocardiographic score is considered as useful predictor of midterm results and restenosis after PMV with Inoue balloon.

BACKGROUND: To investigate the role of alpha-adrenergic receptors in the development of delayed afterdepolarization, the effect of alpha-adrenoceptor stimulation and blockade on ouabain induced delayed afterdepolarization(DDAD) was examined in rabbit heart Purkinje fibers. METHODS: Purkinje fibers, taken from adult rabbit(1.8 - 2.0kg) heart anesthetized with penobarbital, were mounted in a Luicite chamber and superfused with Tyrode's solution. The transmembrane potentials were measured by the conventional microelectrode technique while the fibers were being stimulated with rectangular pulses of 50% above threshold voltage. The delayed afterdepolarizations were induced by overdrive excitation in the presence of ouabain. RESULTS: Delayed afterdepolarizations were not observed during superfusion of the control Tyrode's solution containing propranolol(5x10(-7)M). However, the addition of ouabain in the presence of propranolol elicited DADs which were dose-, time- and drive cycle length- dependent. Phenylephrine(PE ; 10(-7)M), and alpha-adrenoceptor agonist, potentiated the ouabain-induced DAD during the initial superfusion(for 10 or 20 min) of the test Tyrode's solution. However, it was followed by attenuating-effects after a superfusion time of 50 to 60 min. Both effects showed ouabain dose-dependence. Ouabain(2x10(-7)M), in the presence of propranolol, depolarized the maximum diastolic potential and shortened the action potential duration, and the addition of PE(10(-7)M) did not affect the characteristics of action potential except a decrease in velocity of phase 0 depolarization. Prazosin, an alpha1-adrenoceptor antagonist, inhibited the PE's enhancing effects of ouabaininduced DDAD at 20 min superfusion, but did not affect the attenuating-effects of PE at 60 min superfusion. On the other hand, yohimbine, an alpha2-adrenoceptor antagonist, did not affect the PE's DAD potentiating-effects at 20 min superfusion, but inhibited the attenunating-effects of PE at 60 min superfusion. CONCLUSION: It is inferred that alpha-adrenergic stimulation induce delayed afterdepolarization and triggered activity in the rabbits, being responsible for the arrhythmia development, and the effects are mainly due to the action of alpha1-subtpe adrenoceptor stimulation.

PURPOSE: World wide studies have reported many cases of the normal variants of the hepatic artery in healthy individuals. Unfortunately, there are few medical reports in Korea, this study presents the results and analysis of the anatomical variants in the hepatic artery. METHODS: This study analyzed the blood supply of the liver in 131 patients who had received hepatic angiography and superior mesenteric angiography from January 1996 to September 2003 at the Maryknoll general hospital. RESULTS: The hepatic artery pattern with a normal hepatic artery pattern was observed in 101 out of 131 cases (77.1%) ; the right and left hepatic arteries arising from the proper hepatic artery, which arising from the common hepatic artery. The normal variations in the hepatic artery pattern were observed in 30 out of 131 cases (22.9%) ; the replaced right hepatic artery arising from the superior mesenteric artery was observed in 14 out of 131 cases (10.7%). The replaced left hepatic artery arising from the left gastric artery was observed in 6 out of 131 cases (4.6%). The common hepatic artery arising from the superior mesenteric artery was noted in 4 out of 131 cases (3.1%). The accessory left hepatic artery arising from the left gastric artery was observed in 1 out of 67 cases (0.7%). Other variants were noted 5 out of 131 cases (3.8%). CONCLUSION: Knowledge of the patterns and frequency of the variants in hepatic artery is increasing with the larger number of national reports on the hepatic artery variants, which can be great help in surgical operations, hepatic arterial embolization, or liver transplant.
