Right Ventricular Wall Hematoma Secondary to Percutaneous Coronary Intervention

Intramyocardial hematoma is known to be associated with myocardial infarction, chest trauma, coronary artery bypass operation, and complication of percutaneous coronary intervention (PCI). We describe here a rare case of 50-year-old man with a huge right ventricular (RV) wall hematoma which was newly developed two hours after PCI. The patient was treated conservatively with a successful outcome. We discuss plausible mechanisms for the development of RV wall hematoma and treatment options for the case.

Pulmonary Sequestration with Right Coronary Artery Supply

Pulmonary sequestration is an unusual malformation consisting of isolated nonfunctioning lung segments lacking communication with functional tracheobronchial trees. Systemic blood supply is commonly from the thoracic aorta, but arteries occasionally arise from other sites. We report a rare form of pulmonary sequestration with arterial supply from the right coronary artery.

A Case of Left Vocal Cord Palsy and Pulmonary Hypertension in a Patient with Systemic Lupus Erythematosus / 대한류마티스학회지

Laryngeal involvement in systemic lupus erythematosus (SLE) is rare. It can range from mild ulcerations, vocal cord paralysis, and edema to necrotizing vasculitis with airway obstruction. The causes of vocal cord paralysis included vasculitis of the vasa nervorum, neuritis, thromboembolic effect on recurrent laryngeal nerves, and compression of the left recurrent laryngeal nerve by an enlarged left pulmonary artery. Few cases on the association of vocal cord palsy and pulmonary hypertension in SLE patient have been reported. We report a case of left vocal cord palsy and pulmonary hypertension in a patient with SLE who experienced improvement of vocal cord palsy and dyspnea after steroid pulse therapy.

A Case of Primary Malignant Mesenchymoma of the Heart

A malignant mesenchymoma is a rare soft tissue neoplasm that show at least two types of malignant mesenchymal differentiation, in addition to poorly differentiated fibrosarcomatous elements. They grow rapidly, recur frequently, and can be found in a wide variety of location, with most occurring in the extremities. A primary malignant mesenchymoma of the heart is extremely rare, with only 20 cases having been reported worldwide in the English literature up to 2002. We experienced a case of primary cardiac malignant mesenchymoma in a 59 year old female patient, who was admitted due to exertional dyspnea. This case is reported, with a review of the relevant literature.

A Case of Acute Thrombotic Renal Artery Occlusion Treated with Local Urokinase Infusion

Acute thrombotic renal artery occlusion is rarely identified at premortem. Early diagnosis and treatment are crucial for salvage of renal function. We reported a case of successfully dissolved acute thrombotic occlusion of renal artery of 9 hour duration with intra-arterial infusion of urokinase in a 83-year-old man.

Wide QRS tachycardia during treatment with class ic antiarrhythmic agents in a patient with atrial fibrillation: report of 2 cases / 대한내과학회지

Wide QRS tachycardia may represent a rare proarrhythmic effect of some antiarrhythmic agents. Class Ic antiarrhythmic agents produce rate- dependent ventricular conduction slowing due to use-dependent sodium channel blockade, causing QRS prolongation in cases with an increased heart rate. The authors describe two cases of atrial flutter with 1:1 atrioventricular conduction exhibiting a wide QRS tachycardia while on therapy using flecainide and propafenone, and the difficulty in interpreting the ECG.

Atrial Fibrillation with Ventricular Pre-excitation after Intravenous Adenosine as a Treatment of Supraventricular Tachycardia

Adenosine is well known as a safe and effective drug for the termination of paroxysmal supraventricular tachycardia (PSVT), and is also widely used for the termination of both narrow and wide QRS-complex tachycardia of unknown origin in the setting of hemodynamic stability. However, due to a shortening of atrial refractoriness, adenosine can facilitate the induction of atrial fibrillation. A life threatening tachycardia may result from a potential rapid conduction of the atrial fibrillation over an accessory pathway. A case of patient, where the intravenous administration of adenosine, during regular, narrow QRS tachycardia, was followed by atrial fibrillation with rapid conduction over a manifest accessory pathway, is reported.

Evaluating the Necessity of Routine Monitoring of Netilmicin Serum Concentrations in Korean Pediatric Patients with Normal Renal Function / 감염

BACKGROUND: When pediatric patients with normal renal function were given the recommended keep-up amount of aminoglicocide for the use, they showed a better clinical symptom not indicating the poisonous without checking serum concentrations. We studied this subject against the patients who used Netimilcin in order to know if the blood creatinine significantly increases in a clinic and if it reaches the maximum and minimum concentrations without adjusting the amount and the symptom of infection and the result get better. METHODS: We picked the maximum concentration of drugstuffs 30 minutes after injection and its minimum just prior to the next injection within 24~32 hours with a vein injection of 2 mg/kg/dose Netilmicin with the 8 hours difference against 16 patients at the age between 3 months and 14 years. We measured the blood creatinine at the beginning of the treatment and at the closing, and we decided the medicine serum concentration with TDX system and we counted the result of Pharmaco-kinetic parameter with Simkin PC clinical Database system. To check the patients' result of better clinical conditions, leukocyte values and the temperature were measured 72 hours after the treatment. The analysis of statistics was performed with the use of paired t-test. RESULTS: The average age of 16 patients shows 3.5+/-3.2, average weight 15.2+/-8.5 kg, the leukocyte value first 14.9+/-6.6X10X10X10/mm3, and 72 hours after the treatment it shows 6.6+/-1.9X10X10X10/mm3, average temperature fell from 37.7+/-1 celsius into 36.3+/-0.4 celsius. The average drug amount taken in case of patients showed 2.06+/-0.4, the average treatment period was 7.6+/-2.3 days, the maximum serum concentration shows 5.5+/-1.1 mg/mL, the minimum concentration shows 0.5+/-0.3 mg/mL. The average blood creatinine was first 0.52+/-0.19 mg/mL, and at closing 0.46+/-0.11 mg/dL (P=0.209). The minimum concentration didn't show more than 2 mcg/mL, the blood creatinine didn't increase showing 0.5 mg/mL(P=0.201). CONCLUSION: At the result of checking the medicine concentration of Netilmicin in pediatric patients in our clinic, there is no detecting the betterment of the clinical symptom owing to the decrease of the values of leukocyte. There was no necessity to adjust the amount of medicine from the beginning to the end as there was no sign of change of blood creatinine. In view of this result, we can understand that we don't need the regular examination of the medicine concentration about the aminoglicocide from Korean pediatric patients with normal renal function.

Assessment of Myocardial perfusion in Patients with Acute Myocardial infarction

BACKGROUND: Unlike 99mTc-Sestamibi, microbubbles used during myocardial contrast echocardiography (MCE) exist only in the vascular space. Therefore, there may be a difference in the pattern of myocardial perfusion between MCE and 99mTc-Sestamibi Single-Photon Emission Computed Tomography (SPECT) in acute myocardial infarction (AMI). OBJECTIVES: The purpose of this study was to assess myocardial perfusion using MCE with intravenous infusion of perfluorocarbon-exposed sonicated dextrose albumin microbubbles (IV MCE), and to compare it with SPECT and MCE with intracoronary injection of sonicated Hexabrix (IC MCE). METHODS: Seventeen patients with AMI (male 13, age 59.5+/-8.8 years, anterior MI 10) underwent IV MCE at 8.1+/-3.7 days after onset. SPECT and IC MCE were also performed at 1.2+/-1.0 days and 2.0+/-1.5 days from IV MCE respectively. Any revascularization procedures were not performed between three studies. Perfusion defect by three methods was scored semiquantitatively as 1 : normal perfusion, 0.5 : moderate defect, and 0 : severe defect at 16 segments of the left ventricle. RESULTS: 1) Perfusion defect in infarction territory was detected in 15 patients with SPECT, 12 patients with IV MCE and 11 patients with IC MCE. 2) Concordance of perfusion score at each segment was 93% between IV MCE and IC MCE, 65% between IV MCE and SPECT, and 64% between IC MCE and SPECT. 3) With IV MCE, perfusion defect was observed in all 32 segments which were considered as having defect (score 0 and 0.5) by IC MCE. However, defect by IV MCE was found only in 31 out of 108 segments considered as having defect by SPECT. CONCLUSION: In the assessment of myocardial perfusion in pts with AMI, IV MCE and IC MCE showed similar results. However, there was some discrepancy in the extent of perfusion defect between MCE studies and SPECT.

A Case of the Use of Intravenous Immunoglobulin of Treatment for HyperIgE Syndrome

Hyper-IgE syndrome is a rare congenital immune deficiency disease characterized by severe eczema, recurrent infection of the sinopulmonary tract, cold subcutaneous abscess and high serum IgE levels. It is an autosomal dominant disease with incomplete penetrance. We examined the case of a 12 month old infant with hyperIgE syndrome since neonate. The diagnosis of hyper IgE syndrome was made because he had eczema on the face and scalp, subcutaneous absecesses on both external ear canals and markedly elevated serum IgE level with a past history of frequent pulmonary disease. Topical steroid and systemic antibiotics had been unhelpful in treating the eczema and the pulmonary disease. The patient received IVIG for severe eczema and the pulmonary infection. The eczema and pulmonary infection were significantly improved and the patient was discharged after 35days of hospitalization. After 10 months of immunoglobulin therapy, symptoms and general appearance were markedly improved. IVIG can be considered as a choice in the treatment of hyper IgE syndrome.

A Case of Transluminal Stent-Graft Implantation at Right Subclavian Artery Pseudoaneurysm in Behcet's Syndrome

Behcet's disease is an uncommon disorder characterized by clinical triad of relapsing iritis, ulcer of mouth and genitalia. It is now recognized as a systemic disorder with mucocutaneous, ophthalmic, intestinal, respiratory, musculoskeletal, cardiovascular, urogenital and neurologic involvement. Systemic complications affecting the arterial system of disease are rare and mainly the aorta and iliac arteries are involved. Invasion of arterial wall is the most common lesion, predisposing to false aneurysm or rupture. As the standard open surgery, although often difficult, needed second surgeries in 30% to 50% of the patients due to the occurrence of anastomotic false aneurysms, endovascular repair emerged as an alter-native treatment of aneurysmal or pseudoaneurysmal manifestrations in Behcet's disease. We report here a case of the pseudoaneurysm at right subclavian artery which is successfully treated with percutaneous stent-graft.

Comparison of balloon angioplasty , stent insertion and medical therapy in the treatment of single LAD lesion / 대한내과학회지

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(p0.05). 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.

Implantable Cardioverter-Defibrillator (ICD) Therapy: Initial Clinical Experience in 6 Patients

Sudden cardiac death accounts for approximately half of all cardiovascular mortality in the industrialized countries and ventricular tachyarrhythmia is the most common mechanism for this event. Implantable cardioverter-defibrillator (ICD) has been effectively used for prevention of sudden cardiac death in patients with life-threatening ventricular tachyarrhythmias since 1980. Clinical experience with ICD device now exceeds 100,000 implants worldwide and the number of implantation is increasing. In Korea, there is also increasing trend of ICD implantation. The authors report the initial experience of of ICD implantation in 6 patients who had high risk of sudden cardiac death.

Clinical Analysis of Patients with Acute Appendicitis Operated on during

PURPOSE: During the night time decision making on patients suspicious of appendicitis is often difficult because diagnosis and timing for operation are frequently delayed. Therefore, we analyzed above cases and solution is suggested. METHODS: This retrospective study included 360 patients who underwent laparotomies for suspected appendicitis at Hanil Hospital during one year, from March 1998 to Feb. 1999. They were divided into two groups according to presenting time to physician (Day time: 6 a.m. to 6 p.m., Night time: 6 p.m. to 6 a.m.). Sex & age distribution, time of presentation to physician, duration of symptoms, symptoms & physical findings, white blood cell counts, interval from presentation to operation, hospital stay, and pathologic diagnosis were compared. RESULTS: There were no significant differences in sex & age distribution, duration of symptoms, symptoms & physical findings, white blood cell counts, pathologic diagnosis between the two groups. However, during the night time, the interval from presentation to operation was longer than that of the day time (9.15 hours versus 4.83 hours, p<0.001), the rate of delayed appendectomy during the night was 58.0%, the rate of negative laparotomy increased when appendectomy was delayed for more than 12 hours compared with less than 12 hours (28.1% vs 11.7%, p<0.01), and in the cases with perforated appendicitis, delayed appendectomy for more than 12 hours had longer hospital stay compared with less than 12 hours (12 days vs 9.44 days, p<0.01). Factors causing delayed appendectomy were related to the physician (42.5%), lack of anesthetic & nursing supports (19.5%), failure to structure the operation team (20.7%), and patient itself (17.3%). When white blood cell counts were rechecked in the next morning, levels above 10,000 cells/mm3 were highly associated with appendicitis in contrast to that below 10,000 cells/mm3 (91.7% vs 43.5%, p<0.002).

Immediate Results of Manually Crimped NIR Stent

BACKGROUND: The several kinds of coronary stents have proven successful in their role to treat acute or subacute closures after balloon angioplasty as well as to reduce the restenosis rate in de novo lesions. However, investigations continue in order to develop an ideal stent with a strong, highly flexible, radial force, especially useful in cases of tortuous vessels, lesions at bends, and lesions distal to previously deployed stents. The NIR stent is a recently developed balloon-expandable, stainless-steel, slotted tube stent; it is designed for improved flexibility with a higher radial force when compared with the traditional Palmaz-Schatz stent. We report the immediate results of our experience with the NIR stent. The purpose of the present study was to assess the feasibility, safety and efficacy of the deployment of manually crimped NIR stents in patients with complex coronary anatomy as well as the clinical outcomes within the first month. METHODS: Between January and July 1997, 143 NIR stents were implanted in the coronary arteries of 124 patients (male 76%, mean age 56+/-10 years). Sixty-one patients had UAP, 43 had SA, and 20 patients had AMI. RESULTS: 1)Indications of stenting were de novo lesions in 123 (95%) and restenosis lesion in 6 (5%). 2)Frequency of used stent length was 16mm in 65 cases (46%), 32mm in 60 cases (42%), 25 mm in 12 cases (8%), and 9mm in 6 cases (4%). 3)Single stents were implanted in 115 (89%) lesions, and overlapping stenting with 2nd NIR stents in 14 (11%) lesions. 4)Procedural success rate (defined as the angiographically residual stenosis of <30% immediately after the procedure with no major clinical events within 4 weeks after the procedure) was 95.2% (118/124 pts). Angiographic success rate (defined as a residual stenosis of <30% without major dissection) was 96.1% (124/129 lesion). The procedural success rate and the angiographic success rate in calcified lesions and/or thrombi containing lesions were 100%. The procedural success rate and the angiographic success rate in cases of tortuous proximal vessels to the lesion were 91% and 91%, respectively. The procedural success rate and the angiographic success rate in more than 45 degrees angulated lesions were 98% and 94%, respectively. 5)The mean lumen diameter of target lesions was increased from 0.6+/-0.4mm to 3.1+/-0.5mm (p<0.001) after stent implantation. The percent of diameter stenosis was decreased from 82+/-12% to -1+/-13% (p<0.001) after stent implantation. The mean diameter of the reference artery was 3.1+/-0.6mm. 6)Incidence of peristent dissection after stenting was 6.2% (8/129 lesion). 7)The rate of stenting failure was 4.8% (6 pts). There were 2 cases of stent migration, 2 cases of failure to cross the lesion and 2 cases of procedure-related emergency CABG. CONCLUSION: There is a higher tendency for stent migration with manually crinped stents compared with that of premounted stents. However, coronary stenting with manually-crimped NIR stents can be safely performed and may be particularly useful in patients with unfavorable clinical and angiographic characteristics for percutaneous coronary intervention. Follow-up data is needed to assess long term patency of this stent.

A Case of Isolated Congenital Double-Orifice Mitral Valve

Double-orifice mitral valve is a relatively rare congenital abnormality, usually discovered at autopsy or surgery. In most cases, the double-orifice mitral valve causes no hemodynamic effects, sometimes it is regurgitant, and rarely is stenotic. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is often associated with other congenital anomalies and this echocardiographic findings may be confused with other cardiac abnormalities. The authors report a case of isolated congenital double-orifice mitral valve in a 42-year-old woman. Data from the literature are reviewed and the echocardiographic images of the malformation are described.

A Clinical Study of Amosulalol Hydrochloride(YM-09538) on the Antihypertensive Effects in Essential Hypertension

BACKGROUND: Newly developed alpha-, beta-receptor blocker, Amosulalol HCI(YM-09538) was evaluated for its hypotensive efficacy, safety and usefulness in patients with mild to moderate essential hypertension. METHODS: Thirty patients of essential hypertension(male 8, female 22), mean age 55 years were included for the study. Amosulalol HCI was administered 20-60mg daily for 10 weeks and initial starting dose was 10mg twice daily and dose was increased 40mg and 60mg daily in cases of insatisfactory hypotensive effect ever 2 weeks interval. Patients were evaluated every two weeks on blood pressure, pulse rate, improvement of subjective symptoms and side effects. Laboratory examinations were carried out routinely in principle two times before trial and after completion of study. RESULTS: Blood pressure began to fall significantly after tow weeks of administration and changed from initial 172.4mmHg of systolic pressure to final 149.3mmHg and from 104.7mmHg of diastolic pressure to final 92.5mmHg. The response rates were marked fall in 30%, satisfactory fall in 40%, thus overall hypotensive effect was observed in 70%. Pulse rate decreased slightiy but significantly from 4 weeks of administration. Improvement of subjective symptoms were observed in 7 cases out of 12 cases and no significant side effects were observedd except of two mild transitory cases of polyuria and indigestion. Laboratory examination also did not show any significant changes before and after medication. CONCLUSION: The daily administration fo 20-60mg of Amosulalol HCI to moderate essectial hypertension seems to be effective and safe with clinical usefulness.
