RESUMO
BACKGROUND AND OBJECTIVES@#The relationship between operator volume and outcomes of percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) has not been fully investigated. We aimed to investigate the relationship between operator PCI volume and in-hospital outcomes after primary PCI for STEMI.@*METHODS@#Among the total of 44,967 consecutive cases of PCI enrolled in the Korean nationwide, retrospective registry (K-PCI registry), 8,282 patients treated with PCI for STEMI by 373 operators were analyzed. PCI volumes above the 75th percentile (>30 cases/year), between the 75th and 25th percentile (10–30 cases/year), and below the 25th percentile (<10 cases/year) were defined as high, moderate, and low-volume operators, respectively. In-hospital outcomes including mortality, non-fatal myocardial infarction (MI), stent thrombosis, stroke, and urgent repeat PCI were analyzed.@*RESULTS@#The average number of primary PCI cases performed by 373 operators was 22.2 in a year. In-hospital mortality after PCI for STEMI was 571 cases (6.9%). In-hospital outcomes by operator volume showed no significant differences in the death rate, cardiac death, non-fatal MI, and stent thrombosis. However, the rate of urgent repeat PCI tended to be lower in the high-volume operator (0.6%) than in the moderate-(0.7%)/low-(1.5%) volume operator groups (p=0.095). The adjusted odds ratios for adverse in-hospital outcomes were similar in the 3 groups. Multivariate analysis also showed that operator volume was not a predictor for adverse in-hospital outcomes.@*CONCLUSIONS@#In-hospital outcomes after primary PCI for STEMI were not associated with operator volume in the K-PCI registry.

Kawasaki disease is an acute febrile illness frequently developed in infants and children. This disease may involve coronary arteries in 15- 25% of the patients and may progress to coronary aneurysms, ischemic cardiac diseases, and sudden cardiac death. Recently we experienced successful balloon angioplasty followed by coronary stenting in a 15-year old boy with unstable angina and severe coronary arterial occlusive disease secondary to Kawasaki disease. He was diagnosed as unstable angina by 24 hours Holter monitoring, treadmill exercise stress test, echocardiography, and Dipyridamole 99mTc-sestamibi scan. And coronary angiogram revealed severe multiple stenosis and aneurysmal changes due to Kawasaki disease. We successfully performed a percutaneous transluminal coronary angioplasty with stent implantation at left circumflex arterial occlusive lesion.

Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.

BACKGROUND: The early diagnosis of candidemia is critical for the management. The candidemia is known to be associated with 10% of candiduria. But the risk factors in patients with candiduria who are associated with candidemia are not known. We analyzed the risk factors in patients with candiduria who are associated with candidemia. METHODS: We retrospectively reviewed 164 patients with candiduria in Yonsei Medical Center from January 1998 to December 1998. Candiduria patients were divided into two groups. Candiduria patients without candidemia (Group I, 147 patients) and candiduria patients with candidemia (Group II, 17 patients). RESULTS: 1) The mean age of the patients were 57.5 years in group I and 62.5 years in group II. There were no significant differences in the sex ratio between the two groups. 2) Central venous catheter insertion (53%, 100% in group I, II), hypotension (14%, 59% in group I, II), other associated infections (64%, 100% in group I, II), intensive care (41, 76% in group I, II) and fever (46%, 82% in group I, II) were the very significant risk factors in patients with candiduria who were associated with candidemia. 3) Urinary tract procedure (11%, 88% in group I, II), urinary catheter insertion (63%, 94% in group I, II), thrombocytopenia (17%, 41% in group I, II) and DM (8%, 24% in group I, II) were the significant risk factors of candidemia. 4) Candida colony count (cfu/mL) of urine culture was not a significant risk factor. 5) Mortality rate (27%, 59% in group I, II) was significantly high in patients with candidemia. CONCLUSION: Central venous catheter insertion, hypotension, other associated infections, intensive care and fever were the very significant risk factors of candidemia in patients with candiduria.

The aortic dissection is an acute aortic syndrome, caused by an intimal tear and subsequent splitting of the media by the pulsatile blood flow. Though there would be differences in the origin of aortic dissection and therapeutic modalities, the intermediate and long-term prognoses are poor. Endovascular Stent-graft implantation is a revolutionary technique in the treatment of aortic dissection. The endovascular stent grafting in aortic dissection is less invasive and feasible method and is an effective tool for closing the entry site and promoting clot formation, reducing the size of the false lumen. Therefore, endovascular Stent-graft implantation makes possible the desirable remodelling of aorta. We report 33 year-old male with aortic dissection in the thoracic aorta, which was treated with endovascular Stent-graft implantation. Over the favorable remodelling, his dissection was healed completely by the endovascular treatment using Stent-graft.

We report a case of synchronous gastric adenocarcinoma and abdominal non-Hodgkin's lymphoma in a 56-year-old man. An explo-laparotomy was performed for the purpose of palliative resection of the stomach and to evaluate the nature of splenic and peri-pancreatic mass lesions. The pathologic stage of the gastric carcinoma was stage IB (T2N0M0) and the clinical stage of the diffuse large cell type lymphoma was IIA2S. Following surgery and chemotherapy, the patient is now in a disease-free state.

BACKGROUND AND OBJECTIVES: Slow flow or no-reflow during the primary angioplasty is associated with a poor prognosis. The impact of adjuvant balloon inflation on infarct artery flow after successful primary stenting has not yet been studied. Therefore, we investigated the effect of adjuvant balloon inflation on infarct related artery flow after successful stenting in patients with acute myocardial infarction. SUBJECTS AND METHODS: The changes in infarct artery flow before and after adjuvant balloon inflation were assessed in 46 patients with a first episode of acute myocardial infarction (pain duration > 12 hr) who underwent adjuvant balloon inflation after successful primary stenting. Infarct artery flow was evaluated by corrected TIMI frame count (CTFC). RESULTS: After adjuvant balloon inflation, 20 patients (43%) showed a slower flow. The minimal lumen diameter became greater (3.0 > 0.5 mm vs. 3.2 > 0.5 mm, p=0.002) and the residual stenosis lessened (12.2 > 9.6% vs. 6.4 > 8.1%, p 11.5 frames vs. 26.9 > 20.5 frames, p=0.005). On multivariate analysis, only pre-adjuvant balloon CTFC was a predictor of a slower flow after adjuvant balloon inflation (odds ratio 1.148, 95% CI:1.014-1.301). CONCLUSION: Adjuvant balloon inflation after successful primary stenting reduced residual stenosis but deteriorated the infarct artery flow. Further studies are required to define the clinical impact of the positive and negative effects of adjuvant balloon inflation.
