1.Percutaneous transluminal coronary angioplasty for ostial stenosis of the left coronary artery.
Yonsei Medical Journal 1995;36(5):462-465
A 11-year-old girl developed left main coronary artery osteal stenosis after Takayasu's arteritis for which she underwent Percutaneous Transluminal Coronary Angioplasty (PTCA). The narrowing of the left coronary artery was successfully dilated by angioplasty without apparent complication. This one suggests that PTCA may have a potential advantage as a temporary method to postpone the aortocoronary bypass surgery in a child with coronary artery stenosis due to Takayasu's arteritis.

Dissections after percutaneous transluminal coronary angioplasty (PTCA) are risk factors for acute or subacute vessel closures. Intracoronary stenting was developed to avoid these complications by pressing the intimal and medial flaps against the vessel wall, thus reducing the risk of acute closure from thrombus formation. Thirty three coil (Gianturco-Roubin) stents were implanted into the coronary arteries of 32 patients with dissections after PTCA during the period of March 1993 to December 1993. The indications for stent implantation were acute closure in 6 (18.8%), threatened closure in 6 (18.8%) and suboptimal result in 20 (62.4%) patients. Stent insertion were successful in 30 (94%) patients. The diameter stenosis in an immediate angiographic findings after stenting was decreased from 87% to 18% by caliper estimation. Emergency coronary artery bypass graft surgery was required in 1 (3%) patient. A non-Q wave myocardial infarction occurred in 1 (3%) patient. Complications included hematoma of the arterial access site requiring blood transfusion in 4 (12.5%) patients and hemopericardium in 1 (3%) patient. Our initial clinical experience of flexible coil coronary stent imply that stenting is efficacious treatment for acute dissections that are causing acute or threatened closure following angioplasty. The long term follow-up result in all groups of patient who received coronary stents is needed for better evaluation of new devices and prognosis.

To discuss the etiology, pathogenesis, therapies and prescriptions of psycho-cardiological abnormality of patients with coronary heart disease. According to the advance in modern diagnosis and treatment, the authors believed that psycho-cardiological abnormality of patients with coronary heart disease is closely related with mental stresses, like anxiety, depression and insomnia. It is mostly caused by emotional injury and expressed in heart, liver, spleen and kidney. The pathogenesis is heart-liver hyperactivity, yin deficiency in heart and kidney, and insufficiency in heart and spleen. The full recognition of etiology and pathogenesis of psycho-cardiological abnormality of patients with coronary heart disease and the combined treatment of disease and syndromes are of great significance to reduce mental stress and other risk factors, prevent and treat coronary heart disease and improve prognosis.

A successful attempt at percutaneous transluminanl coronary angioplasty (PTCA) to relieve stenosis of the mid-portion of the left anterior descending artery was achieved in a 6-year 9-month old boy who had multiple coronary aneurysms and stenosis due to Kawasaki disease. Despite the progression of coronary stenosis he had been well except for the perfusion defect of the anterior wall of myocardium on 99mTc-MIBI SPECT with dipyridamole infusion until PTCA was carried out after 4-year 4-months of the onset of illness. The area of stenosis was 70% before PTCA and 20% after PTCA. No restenosis at the site of PTCA was observed on follow-up angiography at 26 months after PTCA. This successful attempt may indicate that this procedure should be considered early in subclinical stenosis to prevent ischemic cardiac damage.

BACKGROUNDRandomized clinical trials have demonstrated equivalent safety to bare-metal stents after drug-eluting stents (DES) implantation. However, the DES thrombosis in randomized trials could not be comparable to those observed in clinical practice, frequently including off-label indications. This study sought to assess the incidence of DES thrombosis after implantation of DES in patients with real world coronary artery disease (CAD) in China.
METHODSFrom December 2001 to April 2007, 8190 consecutive patients received the treatment with DES, 5412 patients completed one year follow-up: 2210 with sirolimus-eluting stent Cypher, 1238 with paclitaxel-eluting stent Taxus and 1964 with Chinese sirolimus-eluting stent Firebird. After two years of follow-up, there were 2176 patients (1245 Cypher, 558 Taxus and 373 Firebird). All patients were treated with aspirin and clopidogrel over at least 9 months.
RESULTSAmong 8190 patients, 17 patients had acute stent thrombosis (0.24%): 7 in the Cypher group, 4 Taxus and 6 Firebird; 23 patients had subacute stent thrombosis: 8 Cypher, 6 Taxus and 9 Firebird. The incidence of acute and subacute thrombosis was 0.49%: 0.50% Cypher, 0.63% Taxus and 0.41% Firebird. The incidence of late thrombosis at one year followup was 0.63%: 0.63% Cypher, 0.88% Taxus and 0.46% Firebird; at two year follow-up the incidence was 0.74%: 0.72% Cypher, 0.90% Taxus and 0.54% Firebird. There was no significant difference among three groups at 1 year and 2 years follow-up.
CONCLUSIONThe first generation DES in the treatment of complex lesions are safe and effective if patients are aggressively treated with dual antiplatelet agents.

BACKGROUNDAlthough some certain infectious pathogens could be detected in the patients with coronary artery disease, the roles of these infectious factors in the development of coronary artery diseases remain largely unknown. Since the number of infectious pathogens has been argued to be relative to the coronary artery diseases, we therefore examined whether there is a link between the number of infections and the incidence of in-stent restenosis after stent implantation.
METHODSOne hundred and eighty-one patients were enrolled in this study. Infectious pathogens including serum anti-Chlymydia pneumoniae, cytomegalovirus, Helico pylori, human herpes simplex virus-1, human herpes simplex virus-2 antibodies and hepatitis B virus antigen were measured in all patients before coronary stent implantation. Coronary angiography was performed before, immediately after and 6 months after stent implantation.
RESULTSRestenosis rate 6 months post stent implantation was similar in patients with low pathogen burden (< 3 pathogens, 33.3%) to those with high pathogen burden (> or = 3 pathogens, 29.1%).
CONCLUSIONSPrevious infections with Chlymydia pneumoniae, cytomegalovirus, Helico pylori, human herpes simplex virus-1, human herpes simplex virus-2 and hepatitis B virus do not contribute to the incidence of restenosis after stent implantation.
