Abstract：

Objective To estimate the patterns and frequency of anomalous coronary origin with angiography in the Chinese elderly population and evaluate the correlation between anomalous coronary origin and development of coronary atherosclerotic stenosis. Methods A retrospective analysis was performed on the basis of angiographic data among elderly patients who underwent coronary arteriography in Beijing University First Hospital. Those with anomalous origin of coronary arteries were selected for further assessment and significant stenosis in coronary arteries was recorded.Results Among 2031 patients, 46 patients were found to have anomalous origin of coronary artery,with an incidence rate of 2.3%. Right coronary artery was the most common anomalous vessel, being involved in 26 patients (56.5%). The anomalous origin was more frequent in right coronary artery than in left coronary artery (41.3%). The most common anomaly was right coronary artery arising from left coronary sinus in 13 patients (28.3%). Significant atherosclerotic lesions in the anomalous arteries were seen in 37 patients (80.4%). Conclusions In Chinese elderly population, the anomalous origin of coronary artery is more frequent in right coronary artery, the most common anomaly resides in right coronary artery arising from left coronary sinus. The anomalous coronary artery increases risk for development of coronary atherosclerotic stenosis.

Abstract：

Objective To evaluate the clinical and coronary angiographic features of patients with systemic vasculitis and coronary artery disease. Method Fifteen patients ( 11 male) with systemic vasculitis and coronary artery diseases admitted to our hospital from January 1999 to October 2009 were reviewed. Results There were 6 patients with Behcet's disease, 3 patients with Churg-Strauss syndrome, 2 patients with Takayasu arteritis, 1 patient with polyarteritis nodosa, 1 patient with microscopic polyangiitis, 1 patient with Wegner's granulomatosis and 1 patient with Kawasaki disease. Mean age of this cohort was (39. 3 ± 11.9) years. Adverse coronary events occurred in 4 patients during the inactive phase of systemic vasculitis and in 9 patients during the active phase of systemic vasculitis. Twelve patients were hospitalized with acute myocardial infarction, 2 with angina pectoris and 1 with cardiac tamponade. There were 3 patients with acute left ventricular dysfunction and 3 patients with severe arrhythmias. Compared to patients in the inactive phase, patients in the active phase were younger [(32. 4 ± 8. 1 )years vs. (47.0 ± 10. 2)years],had less risk factors for atherosclerosis ( 1.2 ± 1. 5 to 2. 8 ± 1.7) and the time intervals between coronary artery disease and systemic vasculitis was shorter [0 -7 years( average 1.6 years) to 3 -30 years( average 17.7 years)]. Coronary angiography evidenced coronary stenosis or occlusions in 11 patients, coronary aneurysm and acute thrombosis in 1 patient, coronary aneurysms and occlusions in 1 patient and coronary spasm in 2 patients. LVEF measured by eehocardiography was less than 50% in 8 patients. Conclusion Patients with various systemic vasculitis could develop severe coronary artery disease due to coronary stenosis/occlusion, aneurysma, thrombosis and coronary spasm.

Experience with the use of coronary autoperfusion catheter during complicated angioplasty

Between February and July of 1989, 22 patients underwent the use of the Stack autoperfusion catheter following acute occlusion or obstructive dissection during coronary angioplasty; in 20 cases conventional balloon was used in an attempt to correct the angiographic appearance followed by the use of Stack catheter when results were sub-optimal. Only 1 patient (4.5%) required surgical revascularization. Although our study is not prospective or randomized, our observations suggest a significant impact in decreasing the need for emergency surgical revascularization after complicated coronary angioplasty with the use of this approach.     

Conservative management of ascending aortic dissection caused by percutaneous coronary intervention

Despite notable refinements in percutaneous coronary intervention (PCI) techniques, these procedures are still associated with some morbidity and mortality. A case of elective coronary angioplasty is described that was complicated by coronary dissection and ST-elevation myocardial infarction. Subsequent efforts to recanalize the coronary artery resulted in a catheter-induced tear at the origin of the vessel, with proximal extension of the dissection to involve the ascending aorta. Literature relating to this complication (reviewed here) suggests that surgical management may be indicated under the circumstances we describe. However, a conservative approach was adopted in this instance with excellent long-term results.     

Percutaneous Closure of a Fistulous Giant Coronary Aneurysm

Giant coronary artery aneurysms larger than 50 mm are rare and associated with important complications: namely, rupture. Its workup requires comprehensive imaging and standard treatment is surgical exclusion. We present a 60-year-old patient with previous ostium secundum atrial septal defect surgical closure diagnosed with a giant proximal right coronary artery aneurysm (70 x 62 mm) fistulizing into the right atrium. Percutaneous closure of its aortic origin with an atrial septal occluder was successfully performed, and thrombosis of the aneurysm confirmed on angiography and echocardiogram. This case depicts an innovative, minimally invasive approach to this worrisome entity.

Primary Intracoronary Stenting of Unprotected Left Main Coronary Artery Stenosis in Two Patients with No Contraindication to Surgery: Immediate and Follow-Up Results

Although successful stenting has been reported on protected left main coronary artery or unprotected left main in patients with prohibitive surgical risks or in bail-out situations, no case of left main primary stent implantation in patients without surgical contraindication has yet been reported. We report immediate and late clinical and angiographic results in two patients (57 and 38-year-old men) who had unprotected left main coronary disease, with isolated stenosis on a large and long left main trunk, ideally suitable for stenting. We believe that stenting could change the matter of the contraindication of balloon angioplasty in left main coronary disease. However, further studies with a large number of patients and long-term follow-up are necessary to determine whether this approach will constitute a valuable alternative to surgery in the future.     

Large atherosclerotic left main coronary aneurysm--a case report and review of the literature

Coronary artery aneurysm (CAA) is a rare disorder, characterized by an abnormal dilatation of a localized portion of the coronary artery. It is usually diagnosed incidentally by coronary angiography. Over 50% of coronary artery aneurysms are of atherosclerotic origin. The natural history of coronary aneurysms is not well understood. Their presence is not always considered to be an operative indication; rather, the severity of the associated coronary artery disease (CAD) is what dictates a surgical approach. In the absence of obstructive CAD, the definitive treatment for this condition is unclear. The authors present the case of an isolated saccular left main coronary aneurysm with no associated flow-limiting CAD. The patient was treated medically with antiplatelet and anticoagulant medication with no adverse events at 3, 6, 9, and 12 months of follow-up.     

Management of coronary artery disease: therapeutic options in patients with diabetes

OBJECTIVES: The aim of this review is to discuss the particularities of coronary artery disease (CAD), the effect of intensive medical management and the outcome of percutaneous and surgical revascularization in patients with diabetes mellitus (DM). BACKGROUND: CAD represents the leading cause of death in patients with DM. Numerous clinical, biological and angiographic risk factors have been shown to be associated with CAD in diabetic patients. METHODS: Metabolic abnormalities in patients with DM including insulin resistance, hyperglycemia and dyslipidemia are briefly discussed. Then the potential roles of medical management and of percutaneous and surgical coronary revascularization are more extensively reviewed. RESULTS: More vigorous control of hyperglycemia, hyperlipidemia, hypertension and other risk factors may be of crucial importance for risk reduction. Despite remarkable progress in recent years, the choice of a coronary revascularization strategy remains a challenge in these patients. Diabetic patients with CAD are predisposed to higher cardiovascular events after balloon angioplasty. Whether stenting and new antiplatelet drugs improve the results of percutaneous revascularization in this population needs further evaluation. The superiority of the surgical approach is also not definitely established. Therefore, many aspects of coronary revascularization are still unclear in these patients. CONCLUSIONS: The results of ongoing randomized trials comparing multiple coronary stents to bypass surgery will likely provide some answers to our questions and additional randomized trials evaluating intensive diabetic control with or without coronary revascularization are needed to determine the best therapeutic approach in these patients.     

Intraoperative echocardiographic assessment of the severe isolated ostial stenosis of left main coronary artery before and after surgical patch angioplasty.

Isolated critical ostial stenosis of left main coronary artery is currently treated by conventional bypass surgery. Surgical patch angioplasty in an alternative surgical approach. Transesophageal echocardiography enables visualization of proximal branches of left and right coronary artery. The report describes intraoperative echocardiographic assessment of surgical left main coronary artery angioplasty.     

Thyrocervical trunk perforation: A rare vascular complication during cardiac intervention through right radial approach: A case report and literature review

Trans radial artery access (TRA) is considered a relatively safe approach for percutaneous coronary intervention (PCI), by virtue of its fewer access related peripheral vascular complications. Central arterial complications are rare. We are presenting a case report wherein thyrocervical trunk (TT), a branch of first part of right subclavian artery (RSA) was perforated during intervention through right radial approach, resulting in deep neck hematoma, compressing the trachea and surrounding structure. To our knowledge, this is the first reported case of TT perforation by a hydrophilic wire during a staged cardiac catheterization after primary PCI through right radial approach. Knowledge of such a rare complication, its early recognition, and endovascular treatment might spare a patient with recent acute coronary syndrome on double antiplatelet medications, from surgical intervention and fatal outcome.     

Occasional-operator percutaneous brachial coronary angiography: first, do no arm.

The percutaneous brachial approach to coronary angiography is perceived, rightly or wrongly, to be the easiest of the arm approaches. Predominantly femoral operators may therefore be encouraged to use the percutaneous brachial approach as an occasional procedure. We decided to investigate prospectively whether this was a reasonable strategy by examining outcome in patients who underwent percutaneous brachial cardiac catheterization by occasional brachial operators. Between October 1997 and 2000, 55 patients underwent percutaneous brachial coronary angiography (0.6% of coronary angiographies), aged 66 +/- 10 years, of whom 40 (73%) were male. Chief indications for a brachial approach were peripheral vascular disease in 35 (64%), failed femoral approach in 10 (18%), and orthopnoea in 5 (9%). The procedure was completed successfully in 46 patients (84%). Reasons for failure were failure of access (two), brachial artery spasm (one), inability to negotiate brachial/subclavian tortuosity (two), dissection of the brachial artery (two), and inability to intubate a vein graft (two). Six patients required catheterization from an alternative site (brachial arteriotomy in two, percutaneous transradial in two, femoral in two), with success in all. There were complications of varying severity in 20 patients (36%). Major complications were false aneurysm requiring surgical repair (one), large brachial hematoma requiring surgical exploration and arterial repair (one), and hematoma with clinical median nerve dysfunction for one month. Minor complications included need for repeat coronary angiography via alternative approach (six), weakness of radial pulse < 24 hr (two), brachial artery dissection without clinical sequelae (two), brachial artery spasm terminating procedure (one), and wound oozing (three). Percutaneous brachial coronary angiography is a hazardous procedure when undertaken by occasional brachial operators. Complications are unacceptably frequent. As with all practical procedures, complication rates are likely to be inversely proportional to operator volumes. Patients requiring an arm approach should be referred to operators with high-volume brachial or radial experience.
