BACKGROUND: Balloon PTCA for the distal, long, eccentric coronary artery stenosis will be at high risk for severe dissection or acute occlusion during or after procedure. METHODS AND RESULTS: High Speed Rotational Atherectomy followd by low pressure balloon angioplasty due to distal, long, eccentric coronary artery stenosis. Rotational coronary atherectomy debulked the lesion quickly without difficulty. Rotational Coronary Atherectomy with adjuctive low pressure balloon inflation was successful without event. CONCLUSIONS: This case illustrates the point that complementary deployment of devices may not only improve success of percutaneous coronary intervention, but also may extend its scope.

This study was attempted to observe the rate of oxygen desaturation after full oxygenation in six parturients scheduled for Cesarean sections and six patients scheduled for transabdominal hysterectomies. We calculated the mean rate of fall of arterial saturation (slope of desaturation: less than SaO2 (t2)-SaO2(t1) greater than/t2-t1) and changes in arterial blood gases were observed. All subjects were denitrogenated then a single isolated apnea was carried out. The mean time to obtain 90% saturation was longer in the nonpregnant group (7.5 min vs 3.6 min in parturients). The mean slope of desaturation was steeper in the parturients (-3.34) than the nonpregnant group (-1.52). As far as the oxygen reserve is concerned, the parturients had a lesser margin of safety than the nonpregnant women. It was concluded that the lower the thoracic gas volume (parturients), the lower the alveolar O2 stores and, the more rapidly these stores are depleted.

BACKGROUND: Despite improvement of mortality in acute myocardial infarcrtion, high mortality rate associated with cardiogenic shock remains essentially unchanged. We have reviewed our result of coronary intervention in 15 patients and found relative survival advantage. METHODS: Between Sep. 1992 and Aug. 1995, 15 consecutive patients(M. 10, F. 5) with cardiogenic shock in acute myocardial infarction were treated with coronary intervention using ballon PTCA. IABP was inserted in all patients prior to PTCA. RESULTS: 1) Most commonly found infarct related artery was left anterior descending artery(11) followed by right coronary artery(3) and left main coronary artery(1). 2) Successful reperfusion rate was 86.7%(13/15), and in-hospital mortality rate was 26.7%(4/15). 3) In-hospital mortality was higher in elderly patients compared with less than 70yaer old patients(0%(0/11)vs. 75.0%(3/4)(P < 0.05). 4) Mortality rate was lower in single vessel disease than multivessel disease(11.1%(1/9) vs. 50%(3/6) p<0.05). CONCLUSION: Although this study is uncontrolled, the date suggest that urgent coronary intervention for improving coronary perfusion may reduce mortality of acute myocardial infarction complicated by cardiogenic shock, particularly with single vessel disease and young age group.

Management of unstable angina has evolved progressively. Although coronary angioplasty has recently shown to be relatively safe and effective treatment strategy for unstable angina, aute occlusion due to intracoronary thrombus accumulation during or immediately after coronary angioplasty remains to be one of the most common serious complication of this procedure. Intracoronary urokinase has been used to treat flow-limiting intracoronary thrombus accumulation that complicated initial successful percutaneous transluminal coronary angioplasty(PTCA) in unstable angina patient, which made the patient stablilzed. Thus in patient with flow-limiting intracoronary thrombus accumulation complicating PTCA, intracoronary urokinase proved to be highly effective in restoring vessel patency and preventing acute myocardial infarction. We report a case of successful revascularization with intracoronary infusion of urokinase in patient with intracoronary thrombus accumulation that complicated PTCA.

BACKGROUND: Diastolic dysfuction can be assessed by Doppler echocardiography of mitral inflow. Multiple factors including atrioventricular (AV) delay affect the mitral inflow Doppler indexes. This study was designed to assess the changes of mitral inflow patterns after successful radiofrequency catheter ablation (RFCA) of accessory pathway associated with a short AV interval during pre-excitation in patients with WPW syndrome. METHOD: Echocardiogram, ECG and BP were recorded before and after RFCA for treatment of accessory pathway in 15 patients with WPW syndrome (mean age : 39.7+/-14.6). Doppler indexes including E wave velocity and its velocity time integral (EVTI) ,A wave velocity and its VTI (AVTI), deceleration time (DT), isovolumic relaxation time (IVRT), atrial filling fraction (AFF)and total mitral inflow VTI were measured. RESULTS: 1) PR interval prolonged 94+/-18msec to 174+/-34msec (p<0.001) without significant increment of heart rate and blood pressure after successful RFCA. 2) E/A ratio decreased from 1.29+/-0.58 to 1.1+/-0.53 (<0.001) but E wave velocity, DT and IVRT were not changed significantly after RFCA. 3) A wave velocity and AFF was 55.8+/-17.4msec and 0.35+/-0.08 and increased to 61.8+/-19.9msec and 0.42+/-0.1, respectively after RFCA (p<0.05). 4) Total mitral inflow VTI was 13.6+/-3.5cm and 14.9+/-3.6cm before and after RFCA, respectively (p<0.05) CONCLUSION: These results suggested that normalization of the PR interval after RFCA in patients with WPW syndrome had beneficial hemodynamic effects on the stroke volume by changing mitral inflow Doppler indexes. Therefore, the effect of AV delay is an another parameter to consider when evaluating Doppler indexes of LV filling.
