N/A Inflow characteristics of left and right ventricular filling were assessed in 33 patients with myocardial infarction and 20 normal subjects by pulsed doppler echocardiography. The presence of left and right ventricular diastolic functional change in accordance to the infarct location, serial change of left and right ventricular diastolic function in patients with acute myocardial infarction, and correlation between left ventricular end-diastolic pressure and pulsed doppler echocardiographic incices of left ventricular diastolic function were assessed. Patients with myocardial infarction were subdivided into two groups, the anterior infarct group(20 patients) and the inferior infarct group(13 patients), according to the site of the involved myocardium. Serial doppler echocardiograms were perfarmed three times, within 3 days after onset(lst phase), after about 12 days (2nd phase), and after 4 weeks (3rd phase). 1) Concerning the left ventricular diastolic function, A/E in the anterior infarct group(1.04±0.18) and inferior infarct group(1.07±0.23) was greater than in that of the control group(0.64+0.10)(p<0.05) The corrected isovolumic relaxation time in the anterior infarct group(2.34±0.60 √ms and inferior infarct group(2. 43±0.70 √ms) was longer than in that of the control (1.83±0.31 ms) (p<0.05). The 0.33 area fraction and E area fraction in the anterior infarct group(45±7%, 55±5%, respectively) and inferior infarct group(43+9 53±8%, respectively) were less than in those of the control group(59±9%, 67±5%, respectively) (p< 0.05, p<0.05, respectively) and A area fraction in the anterior infarct group (43±6%) and inferior infarct group(47±8%) was greater than that in the control group(36±7%) (p<0.05). 2) In the right ventricular side, A/E in anterior infarct group(0.86±0.23) and inferior infarct group(1.01±0.16) was greater than in that of contol group(0.62±0.10) (p<0.05), peak A velocity in inferior infarct group(0.44±0.09 m/s) was higher than in those of anterior infarct group(0.36±0.10 m/s) and control group(0,28±0.05 m/s) (p<0.05), 0.33 area fraction and E area fraction in anterior infarct group(43±7%, 52±10%, respectively) and inferior infarct group(42±9%, 50±10%, repectively) were lesser than in those of control group(56±9%, 63±7%) (p<0.05, p<0.05, respectively), and A area fraction in anterior infarct group(48±10%) and inferior infarct group(49±9%) was greater than in that of control group(36±7%) (p<0.05). 3) Serial left ventricular pulsed doppler echocardiogram in 12 patients with acute myocardial infarction showed follwoing results. A/E in phaae 2(0,86±0,17) and phase 3(0.83±0.21) was lesser than in that of phase 1(1.07±0.22) (p<0,05), 0,33 area fraction and E area fraction in phase 2(53±10%, 59±8%, respectively) and phase 3(55±9%, 59±7%, respectively) were greater than in those of phase 1(43±8%, 49±9 respectively) (p<0,05, p<0,05, respectively), A area fraction in phase 2(39±8%) and phase 3(39±8%) was lesser than in phase 1(49±11%) (p<0,05), and these variables were not changed between phase 2 and phase 3. 4) Serial right ventricular pulsed doppler echocardiogram in 12 patients with acute myocardial infarction showed following results, A in phase 2 (0.35±0.10 m/s) and phase 3(0,31+0,06 m/s) was lower than in that of phase 1(0,46±0.09 m/s) (p<0.05), A/E in phase 2(0.92±0.26) and phase 3(0,78±0.18) was lesser than in that of phase 1(1.10±0.16) (p<0.05, p<0.01, respectively), 0,33 area fraction and E area fraction in phase 2(53±10%, 47±9%, respectively) and phase 3(53±8%, 42±9%, respectively) were greater than in those of phase 1(41±10%, 49±8%, respectively) (p<0.05, p<0.05, respectively), and A area fraction in phase 2(47±9%) and phase 3(42±9%) was lesser than in that of phase 1(50±7%) (p<0.05), 5) Left ventricular end diastolic pressure had a signi1icant high correlation with A/E (r=0,76, p=0.01), with 0.08 area fraction (r=0,71, p=0,02), and with E area fraction

With recent advances in transarterial interventional technique, there is a tendency to treat single LAD lesion with balloon angioplasty or stent insertion rather than with medical therapy alone. Therefore, it is important to evaluate the long-term clinical outcomes of such interventional therapy. Methods : Subjects are comprised of patients who underwent coronary angiogram from 1993 to 1996 and diagnosed as having single LAD lesion without decrease of left ventricular fuction. The incidence of major ischemic complications, revascularization and reduction of angina pectoris after different therapeutic strategies in these patients are evaluated. Result : 1) There was total of 190 patients. Patients receiving medical therapy, balloon angioplasty and stent insertion were 70, 75, and 45 respectively. There was no significant difference in mean age, sex ratio, and risk factors of coronary artery occlusive disease between each groups. 2) The medical therapy group(30%) had a significantly lower incidence of proximal stenosis lesion compared to the balloon angioplasty group (45%) and stent insertion group(52%) according to the location of the lesion(p<0.05). The lesion characteristics according to the AHA/ACC criteria showed that the proportion of type A lesion was significantly higher in the balloon angioplasty group(33.3%) compared to the medical therapy group(8.6%) and stent insertion group(13.3%), whereas the proportion of type C lesion was significantly higher in the medical therapy group(41.4%) compared to the balloon angioplasty group(14.3%) and stent insertion group(22.2%). 3) The incidence of ischemic complication were low with 9 out of total 190 patients during follow up consisting of 2 cases of cardiogenic death(1.1%) and 7 cases of acute myocardial infarction(3.7%). 4) During the follow-up period revascularization was performed in 10% of medical therapy group, 27% of balloon angioplasty group and 22% of stent insertion group. There was higher rate of revascularization in patients who received interventional therapy. 5) During the mean follow-up period of 38 months, event-free survival rate was 85% in the patient group receiving medical therapy, 71% in the patient group undergoing balloon angioplasty and 74% in the patient group undergoing stent insertion. There was lower incidence of major events in medical therapy patients, but the difference of the rate among each group was not significant. In considering the patients with proximal LAD stenotic lesion, event-free survival rate was 73% in medical therapy group, 75% in balloon angioplasty group and 81% in stent insertion group, but the difference between each groups did not show any significant difference. 6) Follow-up of each study groups at 6 months, 1 year and 3 years showed that the proportion of chest pain-free patients in balloon angioplasty and stent insertion group were higher than those in medical therapy group despite the lack of statistical significance(p>0.05). Conclusion : For patients with single LAD stenotic lesion interventional therapies such as balloon angioplasty and stent insertion might be more effective without statistical signigicance in reducing chest pain compared to medical therapy. There was no significant difference in the incidence of ischemic complication and rate of revascularization among different study groups. Further studies will be needed to clarify the beneficial effects of interventional coronary artery therapy such as improvement of chest pain, increased exercise capacity, and improved quality of life along with other parameters.

N/A We performed exercise radionuclide ventriculography to evaluate left ventricular (LV) function in 35 patients with pure mitral stenosis (MS). There were 6 males and 29 females ranging from 21 to 63 years of age (mean 37±10 years). We also studied 8 healthy men as control group (mean age 27±5 years. Each patients was evaluated at rest and during maximal exercise on an isokinetic bicycle ergometer. Peak filling rate (PFR), peak ejection rate (PER), ejection fracion (EF), end-diastolic volume(EDV), end-systolic volume (ESV), stroke volume (SV), and cardiac output (CO) were determined by the radionuclide technique. The results were summarized as follows: 1) LV systolic dysfunction and reduced PFR were noted in patients with MS. 2) EDV as well as SV decreased with exercise in patients with MS. 3) No significant increase in EF during exercise compared to rest value was observed because it was caused by reduced EDV and SV during exercise in patients with MS. 4) CO increased with exercise was significantly lower than normal in patients with MS. 5) Patients with MS were divided into two groups according to whether EF increased more than 5% druing exercise compared to resting state or decreased. Significant difference were found between these two groups. Patients with a fall in EF with exercise were older, had larger left atrial size, and had lesser decreased in ESV during exercise.

Background : The goal of percutaneous transluminal angioplasty(PTA) is recanalization of the arterial stenosis or occlusion. The low incidence of serious complications makes PTA an attractive form of treatment for selected patients, especially if the lesions are not severe enough to warrant surgery or the patient is at high operative risk. The purpose of this study was to assess the feasibility, safety, and efficacy of PTA as an alternative or primary therapy for whole body arterial occlusive disease. Methods : PTA was performed in 397 patients(male 342, female 55 : mean age 58.9±12.4 yr) with arterial occlusive disease. The patients were followed after PTA for a mean period of 22±11months. The information on restenosis, recurrence of symptom, redo-PTA, bypass surgery and amputation was obtained by follow-up angiography, plethysmography and self-administered questionnaire. Results : In the 313 patients who underwent PTA for low extremity vascular disease, the overall success rate was 80.6%. Technical success rate for the iliac lesions was 84.7%, for the femoropopliteal lesions 74.8%, and for the infrapopliteal lesions 78.6% respectively. These results showed that outcome for iliac lesions were significantly better than those for femoropopliteal lesions(p<0.001). The technical success rate for the low extremity vessels was greater in the stenting group than in the ballooning group(98.2% vs 68.9%, p<0.001). In 260 lesions followed after PTA for low extremity vascular disease, cumulative patency rate at 3 years was greater in the iliac artery group than in the femoropopliteal artery group(84.6% vs 50.8%, p<0.001). In femoropopliteal lesions, cumulative patency rate at 3 year was greater for intervention of stenotic lesions compared to occlusive lesions(60.3% vs 38.1%, p<0.05). Carotid artery stenting in 25 patients(35 lesions) was successful in all lesions. Angiography and/or duplex sonography which was performed at 5.5±2.6 months in 18 patients(24 lesions) followed after carotid stenting revealed no evidence of restenosis. Subclavian artery stenting in the 16 patients(17 lesions) was successful in 16 lesions(94%). Renal artery stenting in the 17 patients(18 lesions) was successful in all lesions. Angiography at 8.5±3.5 months in 6 patients(6 lesions) followed after renal stenting revealed no evidence of restenosis. PTA for total occlusion of abdominal aorta was successful in 11 lesions(84.6%) of the 13 lesions. Angiography at 13±12 months in 7 patients(7 lesions) followed after PTA for abdominal aorta revealed significant restenosis in 2 patients. Minor complications during the PTA for peripheral disease occurred in 25 patients of 397 patients. Conclusion : PTA for whole body arterial occlusive disease can be performed with an excellent technical success rate and minimal morbidity and mortality. PTA for carotid, subclavian, renal, iliac artery or abdominal aorta represents a true alternative to vascular surgery as a first-line treatment. Despite acceptable initial success rate, PTA for femoropopliteal or infrapopliteal artery warrants further validation because it has high incidence of clinical restenosis during the follow-up periods.

N/A Percutaneous mitral balloon valvuloplasty (PMV) using the double-balloon technique was performed in 28 symptomatic patients with mitral stenosis who were candidates for mitral valve commissurotomy. There were 21 women and 7 men with a mean age 38±10 years (range 23 to 57). PMV in 28 patients with moderate to severe mitral stenosis (including 3 with a fluoroscopic calcified valve) resulted in an increase mitral valve area (0.9±0.2 to 2.2±0,7cm, p<0.0001) by Gorlin`s formula, and a decrease in mean diastolic mitral pressure gradient (16.8±5.7 to 6.1±3.9mmHg, p<0.0001), and mean left atrial pressure (23.6±6.7 to 11.7±5.8mmHg, p<0. 0001). And also cardiac output increased (4.8±1.0 to 5. 8±1.5L/min, p<0.005) and mean pulmonary artery pressure decreased (32±12 to 24±9mmHg, p<0.05). Mitral regurgitation developed or increased in severity after PMV in 15 (53.6%) patients, grade 3mitral regurgitation in 2 and no mitral regurgitation in 12 patients. Oxymetric studies performed immediately after PMV demonstrated a small left-to-right shunt (pulmonary-to-systemic blood flow ratios>1.5) through the interatrial communication in 4 patients. Follow up echocardiography showed improvement in mitral valve area by 2-D and Doppler pressure half-time (0.9±0.2 to 1.8±0.5 and 0.8±0.2 to 1.7±0.4 cm, p<0.0001), increase of mitral EF slope (13±7 to 37±17mm/ sec, p<0.0001) and decrease peak E mitral velocity (209±32 to 142±32cm/sec, p<0.0001). Transient cerebral embolic phenomenon just after PMV was observed in 1 patient and cerebral embolic infarction with hemorrhage requiring surgery developed in 1 patient. PMV using the double-balloon technique is safe and effective procedure to relieve mitral valve obstruction and could be an alternative to surgical mitral commissurotomy in selected patients with mitral stenosis.

N/A To compare the myocardial viability in patients suffering from total occlusion of the right coronary artery (RCA) with the angiographic collaterals, intracoronary injection of Thallium-201 (T1-201) was done to 14 coronary artery disease (CAD) patients (pts) with total occlusion of RCA and into four normal subjects for control. All 14 CAD pts had Grade 2 or 3 collateral circulations. There were 14 male and 4 females, and their ages ranged from 31 to 70 years. In nine pts, T1-201 was injected into left main coronary artery (LCA) (300∼350 μCi) to evaluate the myocardial viability of RCA territory through collateral circulations. The remaining five pts received T1-201 into RCA (200-250 μCi) because two had intraarterial bridging collaterals and three had previous successful PTCA. Planar & SPECT myocardial perfusion images were obtained 30 minutes, and four to five hours after T1-201 reinjection. Intravenous T1-201 reinjection (six pts) or Tc-99m-MIBI (two pts) were also performed in eight CAD pts. Intracoronary myocardial perfusion images were compared with intravenous T1-201(IV T1-201) images, EGG, and ventriculography. Intracoronary TI-201 images proved to be superior to that of IV T1-201 due to better myocardial to background uptake ratio and more effective in the detection of viable tissue. We also found that perfusion defects were smaller on intracoronary T1-201 images than those on the IV T1-201. All of the 14 CAD pts had either mostly viable myocardium (seven pts) or large area of T1-201 perfusion (seven pts) in RCA territory, however ventriculographic wall motion and ECG did not correlate well with intracoronary myocardial perfusion images. In conclusion, total RCA occlusion patients with well developed collateral circulation had large area of viable myocardial in the corresponding territory.

N/A 123I-Iodine-metaiodobenzylguanidine(MIBG) which is a norepinephrine analogue, can be used to evaluate the sympathetic innervation of the heart. In this study, cardiac imaging with 123I-MIBG was performed in patients with 9 dilated cardiomyopathy, 2 ischemic cardiomyopathy and 1 acute myocardial infarction to evaluate the sympathetic nervous function. 123II-MIBG imaging showed multifocal defects (8), diffuse defect (2), near non-visualization (2). The defects of MIBG scans were found to be larger and more severe on 4 hours image than 30 minutes. Heart to lung, heart to mediastinum ratios were decreased at 4 hours than those at 30 minutes. Measured LVEF values were not correlated with the severity of MIBG uptake. Tc-99m-MIBI imaging was also performed in all patients to find the relationship with 123I-MIBG scan. Tc-99m-MIBI scan showed multifocal defects in 9 patients, diffuse defects in 1 patient and no defect in 2 patients. The defects are similar in size, severity and extent, but more larger and severe on 123I-MIBG imaging. Therefore, cardiac 123I-MIBG imaging is a useful method to evaluate the sympathetic nervous function in cardiomyopathy.

In elderly patients, the vital parameters tend to fluctuate based on the blood volume status, which may cause sudden hypovolemic shock if the postoperative bleeding continues. Particularly, those who undergo surgery for arthritis needs to pay extra attention because the bleeding may persist over the joints after the surgery. Therefore, appropriate pain control is required to reduce the postoperative blood loss. This retrospective chart review study was conducted to assess the postoperative pain control and reduction of blood loss with a single injection of saphenous nerve block (SNB) in elderly patients with osteoarthritis. We reviewed the electronic medical records of patients who underwent knee total arthroplasty with spinal anesthesia between January and May 2016. A total of 51 patients participated in this study. All patients were treated with intravenous patient-controlled analgesia for the postoperative pain control, and additional analgesic agents were administered at a visual analogue scale above a score of 6. In 25 patients, SNB was performed using ultrasound with the administration of 0.75% ropivacaine (15 mL) after the surgery. Patients who received additional analgesics were significantly low in the nerve block group (P=0.009). Additionally, the volume of blood loss from catheter drainage was significantly low at 2 and 3 days postoperatively (P=0.013 and P=0.041, respectively) in the nerve block group. In patients who underwent total knee arthroplasty with osteoarthritis, only a single injection of saphenous nerve block was sufficient for the postoperative pain control and reduced bleeding.
