摘要:

AbstractRecent reports have suggested that angioplasty may cause or accelerate coronary arterial stenoses secondary to traumatic injury. Ninety‐four coronary angiograms performed in a 1 yr period were reviewed in patients who had successful coronary angioplasty 6 to 30 mo (mean 10.7) prior to restudy. Restenosis was found in 43 of 140 dilated lesions (31%) and in 41 of 94 patients (44%). Thirty‐three (35%) patients had new or progressive lesions outside the angioplasty site. New or progressive lesions occurred with similar frequency in the arteries that did not have angioplasty (23/155 = 15%) as in the arteries that did (13/127 = 10%; chi‐square n.s.). In the arteries which underwent angioplasty, new or progressive lesions occurred as commonly proximal to the PTCA site (7/14, 50%) as distal (6/13, 46%). New or progressive lesions occurred in 29% of patients with concomitant restenosis, and 40% of those without restenosis (chi‐square n.s.). No clinical, angiographic, or procedural factors distinguished patients with new and progressive lesions in target vessels from those without these lesions in target vessels. Patients with progressive lesions anywhere in the coronary tree were more likely to have had a shorter duration of anginal symptoms before angioplasty and a family history of coronary disease when compared with patients without progressive atherosclerosis. In conclusion, new and progressive lesions outside the angioplasty site occur after the procedure but appear unrelated to the restenosis process or traumatic injury by angioplasty instrume

摘要:

AbstractCritical mitral stenosis in selected patients may be treated successfully with percutaneous mitral valvuloplasty. Complications of this procedure, particularly an atrial septal defect following transseptal approach, are generally of minor clinical significance.We describe a woman who initially underwent a successful percutaneous double‐balloon mitral valvuloplasty via the transseptal approach. Three months later she presented with right‐sided heart failure. Color Doppler echocardiography and cardiac catheterization demonstrated an atrial septal defect (ASD) as well as restenosis of the mitral valve.We conclude that significant ASDs may occur following transseptal mitral valvuloplasty with appearance of right ventricular failure and that color Doppler imaging aids in the diagnosis of this new variant of the classical Lutembacher syndr

摘要:

AbstractA patient with cardiogenic shock had typical electrocardiographic findings of acute anterior transmural myocardial infarction. Cardiac catheterization revealed normal coronary arteries and severe biventricular failure. Postmorten examination confirmed normal coronary arteries; acute myocarditis, but no evidence for infarction, was found. Electrocardiographic changes of myocarditis may be indistinguishable from acute transmural infarction. In suspected cases, cardiac catheterization should be considered prior to thrombolytic therapy.

摘要:

AbstractWe report a case of perforation of the left brachiocephalic vein after insertion through the left internal jugular vein. Entrapment of air in the balloon occurred, possibly due to high surrounding tissue pressure at its base, preventing deflation. We emphasize the potential hazards of catheterization via the left internal jugular vein.

摘要:

AbstractWe describe a unique method employing a transseptal sheath as a “guiding catheter” that allows contralateral retrograde femoral artery access to perform balloon angioplasty of proximal superficial femoral artery lesions. This technique simplifies arterial access, provides support for crossing lesions, and allows angiographic visualization of target lesions during the proced

摘要:

AbstractIn this case report of a patient undergoing angioplasty for cardiogenic shock during acute myocardial infarction, recurrent occlusion resulted in recurrence of shock. Atherectomy reestablished lasting patency and reversed the patient's hemodynamic collapse. Atherectomy deserves further investigation as a means to salvage vessel patency during unsuccessful coronary angioplasty.

摘要:

AbstractLeft ventricular rupture resulting in death has been reported to be a complication of percutaneous mitral commissurotomy. We report a 71‐year‐old man in whom a left ventricular rupture occurred during percutaneous mitral commissurotomy and resulted in hemodynamic collapse due to acute cardiac tamponade. The patient was stabilized using percutaneously instituted cardiopulmonary bypass support with subsequent repair of the left ventricle and successful mitral valve replacement. Three months later this patient remains in New York Heart Clas

摘要:

AbstractCoronary artery anomalies were found in 1,686 patients (1.3% incidence) undergoing coronary arteriography at the Cleveland Clinic Foundation from 1960 to 1988. Of the 1,686 patients, 1,461 (87%) had anomalies of origin and distribution, and 225 (13%) had coronary artery fistulae. Most coronary anomalies did not result in signs, symptoms, or complications, and usually were discovered as incidental findings at the time of catheterization. Eighty‐one percent were “benign” anomalies: (1) separate origin of the left anerior descending and circumflex from the left sinus of Valsalva; (2) ectopic origin of the circumflex from the right sinus of Valsalva; (3) ectopic coronary origin from the posterior sinus of Valsalva; (4) anomalous coronary origin from the ascending aorta; (5) absent circumflex; (6) intercoronary communications; and (7) small coronary artery fistulae. Other anomalies may be associated with potentially serious sequelae such as angina pectoris, myocardial infarction, syncope, cardiac arrhythmias, congestive heart failure, or sudden death. Potentially serious anomalies include: (1) ectopic coronary origin from the pulmonary artery; (2) ectopic coronary origin from the opposite aortic sinus; (3) single coronary artery; and (4) large coronary fistulae. Coronary artery anomalies require accurate recognition, and at times, surgical corre
