Thirty-five year-old Amadeus Mozart died in Vienna after an acute illness that lasted only 15 days but no consensus has been reached on the cause of his death. From many letters written by his farther it is almost certain that he experienced at least three episodes of acute rheumatic fever attack in his childhood, and a relapse of rheumatic fever was suggested to have killed Mozart, although death from acute rheumatic fever is very rare in adults. His last illness was characterized by high fever, massive edema, vomiting and skin rash. His last illness can be explained by infectious endocarditis and heart failure. During his last hours, he was given phlebotomy, possibly for the third time in two weeks, and soon after he became unconscious and died. As such, phlebotomy performed on a man dehydrated by high fever and vomiting may have caused systemic shock. In summary, Mozart probably died from chronic rheumatic heart disease complicated by infective endocarditis and heart failure, and repeated phlebotomy-induced hypovolemic shock.

Since after first report of percutaneous transluminal coronary angioplasty in 1977, improved operator technique and advanced equipment designs have resulted in an increase in primary success rate from 67% to 92% in recent days. Despite these improvement, acute closure and restenosis remain as serious limitations to both the short and long-term success of PTCA. Coronary artery stents have been proposed as a method of treating acute closure and preventing restenosis. We implanted 21 balloon expandable Palmaz-Schatz Stent in selected 21 Patients(mean age 62+/-8 years, M/F : 16/5) with atherosclerotic coronary artery disease. The indications were elective stenting in 17, acute dissection postangioplasty in 2 and restenosis following angioplasty in 2. The clinical diagnosis of the subjects was unstable angina in 12 pts(57%), stable angina in 1, and post infarction angina in 8 including 6 acute myocardial infarction. The target vessel was right coronary artery In 12(57%), left anterior descending artery in 6(29%) and left circumflex in 3(14%). The size of implanted stent was 3mm in 15, 3.5mm in 5 and 4.0mm in 1. The morphology of attempted lesion was AHA/ACC classification type A in 1, type B in 17(B1 ; 1, B2 ; 16) and type C in 3. Angiographic findings were 1-vessel disease in 16 patients, 2-vessel disease in 4 and 3-vessel disease in 1. Coronary artery stenting wast technically successful in 21 all patients(100%) and complications included subacute total occlusion 1 week after stenting in 1, which was recanalized successfully by repeat PTCA without myocardial infarction, prolonged sinus arrest after stenting due to microembolism in 1 and puncture site bleeding requiring transfusion in 1. CONCLUSION: Coronary artery stenting was a safe and effective procedure to obtain adequate coronary blood flow in selected patients but long-term efficacy of primary elective coronary stenting should be evaluated prospectively.

To assess the efficacy of 2 different mitral balloon valvotomy (PMV) techniques, PMV was performed using Inoue balloon (I) in 35 pts and double balloon (D) in 33 pts with mitral stenosis (male 27, female 41, mean age 42+/-12 years). The success rate of PMV was 89%(31/35 pts) in I group and 97%(33/33 pts) in D group. Mitral valve area after dilation increased equally effectively in both groups (I and D) from 0.9+/-0.2 and 0.8+/-0.2 to 1.9+/-0.2 and 1.9+/-0.3cm2 respectively (p<0.0001). There were no differences in degree of improvement of cardiac output, mitral gradient, left atrial pressure, pulmonary artery pressure and various doppler echocardiographic findings in both groups, but EF slope was more improved from 13+/-7 to 48+/-16 mm/sec in D group than those (from 15+/-6 to 39+/-15mm/sec) of I group. Increments of long and short diameters of mitral valve orifice by 2D-echocardiogram were 1.1+/-0.6 and 0.3+/-0.3cm in D group and 0.9+/-0.5, 0.4+/-0.3cm in I group. The ratio of long and short diameter increase was significantly larger in D than that of I group (long/short 2.8+/-0.7 vs 2.4+/-0.7, p<0.05) and short diameter of orifice after dilation was more improved in I than that of D group (1.1+/-0.2 vs 1.0+/-0.2cm p<0.05). Complications included deflation failure of Inoue balloon in 2, and cerebral embolic episode in 1 (D). Incidence of increased mitral regurgitation was 50% in D and 45% in I, development of ASD (Qp/Qs>1.2) was 20% in D, 13% in I group respectively and mean amount of left to right shunt (Qp/Qs) was 1.7+/-0.3 in D and 1.5+/-0.1 in I group. Total procedure and fluoroscopic time were 84+/-24 and 25+/-11 min. in D and 56+/-20 and 16+/-6 min. In I, which had statistically significant differences (p<0.002). Thus we concluded PMV using Inoue or double balloons was equally effective in selected patients. Total procedure and fluoroscopic time of Inoue balloon technique were significantly shorter than those of double balloons. Double balloon technique had more tendency of longitudinal splitting of the commissures.

BACKGROUND: Coronary artery bypass grafts obtained from internal mammary artery(IMA) have a greater patency rate than do saphenous vein grafts(SVG). The release or production of endothelium-derived relaxing factor(EDRF), which regulates blood flow and inhibits platelets function, may contribute to the higher patency rate of IMA. In order to evaluate the difference between endothelium dependent relaxation in IMA and in grafted saphenous veins, we observed acetylcholine responses of IMAs and SVGs in humans. METHOD: Incremental dose if acetylcholine(Ach:A1-20, A2-50, A3-100microg) or single dose if acetylcholine(A3) were infused into the non-grafted IMA in 16 patients with different clinical presentation of coronary artery disease(3 with stable angina, 2 with acute myocardial infarction 4 with variant angina and atypical chest pain syndrome in 7). After the dose-response to Ach was completed nitroglycerine 200microg was injected into the IMA. Graded dose of Ach (A1, A2, A3) was also infused in 13 grafted saphenous veins(SVG). RESULTS: The overall vascular effects of Ach into the IMA were dilatory responses regardless of different clinical presentation. Two or 3 minutes after Ach injection, the diameter of IMA increased by 9.2%(A1) and 16. 7%(A3) respectively(p<0.01). Maximal dilatory response after A3 was comparable to that after nitroglycerin injection. Angiographically normal segements of SVGs also increased its diameter 2 minutes after Ach injection (7.2% with A1, 6.9% with A2 and 8.5% with A3). Thus the degree of relaxation of IMA was more prominent than that of SVGs. Angiographically dicreased segments of SVGs had no response after Ach injection. The overall responses of native coronary artery to Ach was dose dependant constriction. CONCLUSION: Injection of Ach to IMA and angiographically normal segments of SVGs caused vascular dilatation probably due to EDRF response. However the degree of relaxation was more prominent in IMA than in SVG. Angiographically diseased segments of SVGs had no response to Ach injection, suggesting that diseased SVG does not produce EDRF. However the finding of a consistent Ach-induced EDRF relaxation in the SVGs despite of constrictive response in the majority of native coronary arteries might suggest that the regenerated endothelial cell in the SVGs were probably of saphenous vein origin rather than derived from the coronary arterial endothelium.

BACKGROUND: Large series of patients with symptomatic mitral stenosis have undergone percutaneous mitral balloon valvuloplasty(PMV) with use of the Inoue or double balloon technique. But to date the result of the two procedure have not been compared with a single series prospectively. METHODS: In order to assess the immediate hemodynamic results and the longterm efficacy of two different PMV technique, a prospective, randomized trial of PMV was performed using the Inoue balloon(Toray, I group) in 59 patients and the double balloons(a pair of Mansfield balloon. D group) in 61 patients with moderate to severe mitral stenosis. Before valvuloplasty, the patients series were comparable with regard to average age. gender, most clinical and echocardiographic variables. All the patients(120 patients, M/F 38/82, mean age 41+/-11 year) were preselected with good echoscore> or =9. RESULTS: The success rate was 83% in the I group and 89% in the D group when the success defined as mitral valve area(MVA)> or =1.5cm2 with 25% gain in MVA and mitral regurgitation> or =2+ at the end of procedure. The magnitude of increase of mitral valve area and decrease of mitral gradient, left atrial pressure and pulmonary arterial pressure were not significantly different in the Inoue and double balloon series(1.0+/-0.4 and 1.1+/-0.4cm2 for mitral vale area, 10.2+/-6.6 and 11.7+/-6.4mmHg for mitral gradient, 10.5+/-6,4 and 12.9 +/-7,3mmHg for left atrial pressure, and 8.7+/-7.3 and 10.1+/-9.4 mmHg for pulmonary artrial pressure respectively). Immediatly after dilation, the long diameter changes of the mitral orifice was more prominent in the D group(from 1.0+/-0.2 to 2.6+/-0.4cm p<0.01) than those in I series(from 1.1+/-0.4 to 2.3+/-0.3cm) Moreover, the magnitude of increase in the EF slop was significantly larger in the D group(31.9+/-17.0 vs 21.8+/-14.2mm/sec, p<0.001). The duration of total procedure(56+/-20 vs 84+/-24 min, p<0.002) and the fluoroscopic time (15+/-6 vs 25+/-11min, p<0.002) was significantly shorter in group I. The incidence of left to right shunt at the atrial level(Qp/Qs>1.5) was 3.4% in group I and 4.9% in group D. Severe mitral regurgitation> or =3+ occurred in 2 patients in each I(3.4%) and D(3.3%) group respectively. At follow-up, the mitral valve area was significantly decreased(1.6 in group I vs 1.8cm2 in group D, P<0.001 vs immediate after MVA) at 6 months and well maintained at 1 year follow-up in both groups. Until 6 months after valvuloplasty, the long diameter of orifice was greater in group D, however the difference was not apparent at 1 year follow-up. CONCLUSION: The Inoue and double balloon techniques obtained equivalent results of the success rate and the frequently of complications. However, the Inoue balloon technique reduced significantly fluoroscope time and total procedure duration. Double balloon technique afforded a longer longitudinal splitting of the commissure immediatly and 6 months after valvuloplasty. However the differences was not apparent at 1 year follow-up. Increased MVA was well maintained at 1 year in both groups. The severity of the newly developed mitral regurgitation immediately after valvuloplasty reduced significantly in 53% of the Inoue and 43% in the double balloon group at 6 months follow-up. In the view point of similiar immediate and late results of the two methods, the stepwise dilation with Doppler echocardiographic monitoring during the Inoue procedure appeared to be cumbersome.

Intracoronary acetylcholine and intravenous ergonovine tests have been used to induce coronary artery spasm. To evaluate the usefulness of these provocative tests, acetylcholine and ergonovine tests were performed in 86 patients with normal or near normal coronary angiograms(clinically variant angina in 30, effort angina in 6, unstable angina in 5, myocardial infarction in 6, atypical chest pain in 39 patients). Acetylcholine was injected into each coronary artery in incremental doses (0.02, 0.05 and 0.1 mg into left coronary artery, 0.02 and 0.05 mg into right coronary artery) and ergonovin was given intravenously in graded doses of 0.05, 0.1 and 0.2 mg after completion of acetylcholine test. The results were as follow : 1) Among 86 patients, both acetylcholine and ergonovine tests were positive in 29 patients, both tests were negative in 50 patients, and acetylcholine test was positive but ergonovine test was negative in 7 patients ; The responses of acetylcholine and ergonovine tests were concordant in 92% of patients. The sensitvity and specificity of the acetylcholine test with reference to ergonovine test were 100% and 88% respectively. 2) In 7 patients(8%) acetylcholine test was positive but ergonovine test was negative, and this group may represent a spectrum of coronary spasm syndrome. CONCLUSION: Acetylcholine test is a safe and useful provocative test for coronary artery spasm, especially in the multivessel spasm.

BACKGROUND: The HMG-CoA reductase inhibitor is the most powerful cholesterol lowering drug and lovastatin, simvastatin and pravastatin are used clinically. We studied the efficacy and side effects of pravastatin monotherapy in patients with hypercholesterolemia(type IIa or IIb). METHODS: Patients who showed 12-hours fasting serum total cholesterol level more than 240mg% were enrolled to diet therapy. After 4weeks of diet therapy, serum lipid profiles were checked and the drug therapy was considered according to NCEP guidelines. The pravastatin 5mg po bid was administrated and the patients had regular follow-up every 2weeks for 8week. RESULTS: The total study population was 20 patients and the mean age of them was 55 years old (55+/-18, M : F=6 : 14). There were a few side effects in 5% of study patients and no patient discontinued pravastatin due to side effects.The side effect was G-I trouble and there were not other side effects. Serum CK was elevated in only one patient but the elevation was mild(less than 3 times) and transient. The LFT, serum uric acid, BUN and creatinine level did not show any significant changes during therapy. Among lipid profiles, total cholesterol, LDL-cholesterol and apolipoprotein B level showed significant reduction after therapy and the maximum reduction was achieved after 2week of therapy. The mean reduction was 20%, 33% and 23% respectively. HDL-cholesterol and apolipoprotein A1 11% and 17% respectively. The triglyceride level did not show any changes during therapy but in one type IIb patient, the triglyceride level decreased significantly. CONCLUSIONS: The pravastatin is effective and safe in patients with hypercholesterolemia.

BACKGROUND: Despite improved operator technique and advanced equipment designs, acute closure and restenosis remain as serious limitations to both the short and long-term success of balloon angioplasty. Atherectomy is a new transluminal interventional technique for the treatment of coronary artery obstructive disease. We evaluate preliminary experience of directonal coronary atherectomy (DCA) for complex coronary artery lesions. METHODS: We tried DCA in the 16 lesions of 15 nonrandomized sequential patients(mean age 66 years, M/F : 12/3) with coronary artery lesions that were ostial lesion in 4, ulcerated and/or eccentric in 13, restenosis after PTCA in 2 and after stent implantation in 2. The target vessel was right coronary artery in 7 and left anterior descending artery in 9. RESULTS: Primary success was achieved in 14 of 16 lesions (88%) by atherectomy and in 5(36%) by additional use of balloon angioplasty. Atherectomy retrieved tissue in 15 out of 15 attempts(100%). One patients suffered acute closure due to large dissection during the DCA which was solved successfully after stent implantation. CONCLUSIONS: Atherectomy can predictably treat selected patients with eccentric, ostial bulky coronary lesions with overall safety comparable to that of conventional balloon angioplasty, although the procedure as currently performed does not appear to prevent restenosis.
