A 78-year-old man with atherosclerotic heart disease developed extensive right ventricular infarction fibrosis with aneurysm formation following right coronary artery occlusion. No symptoms of right-sided heart failure were present. Postmortem examination revealed that 40% of the right ventricle, 11% of the septum and 7% of the left ventricular free wall were infarcted due to right coronary artery occlusion. This is the first documented case of isolated aneurysm of the right ventricle following infarction and it demonstrates that even extensive right ventricular destruction may be present without symptoms. 相似文献

Idiopathic aneurysmal dilatations of the right atrium are rare anomalies. We report one such case of a young man presenting with fatigue, abdominal distension, pedal oedema, unremarkable cardiac examination except for raised jugular venous pressure, an electrocardiogram showing normal sinus rhythm with right bundle-branch block, and an radiograph of the chest showing cardiomegaly. The echocardiographic examination revealed a giant right atrium with low pressure tricuspid regurgitation. The computed tomography confirmed the findings of two-dimensional echocardiography. He was put on medical treatment and remained symptomatically controlled on follow-up. 相似文献

A metastatic synovial sarcoma in the right atrium and ventricle is described. A 36-year-old man was admitted to our hospital with generalized fatigue, dyspnoea, and precordial pain. Transthoracic echocardiography demonstrated a metastatic tumour in both the right atrium and right ventricle and revealed obstruction of the inflow tract of the right ventricle caused by a metastatic right atrial tumour. Thoracic computed tomography revealed a pleural-based paravertebral mass in the left intrathoracic cavity and multiple pulmonary nodules in both lungs. Cardiac surgery was performed for palliative treatment due to right cardiac failure and a risk of fatal embolization. The patient died 12 months after the cardiac surgery. 相似文献

Right ventricular wall thickness (T) measurements were made in 111 patients by echocardiography to evaluate their usefulness in diagnossing right ventricular hypertrophy (RVH) and in predicting right ventricular peak systolic pressure (P). Anatomic and echocardiographic findings of RVH were compared in 36 of 111 subjects: diastolic T (dT) and systolic T (sT) had a sensitivity of 90 and 34% and a specificity of 94 and 100%, respectively, in the diagnosis of RVH. Echocardiographic and hemodynamic findings were compared in the remaining 75 of 111 patients undergoing cardiac catheterization: dt was 6.5 +/- 2.7 mm in 46 patients with elevated P (58.2 +/- 30.2 mm Hg) versus 3.8 +/- 0.9 in 29 patients with normal P (26.3 +/- 2.7 mm Hg) (p less than 0.01). The dT and P had a linear correlation (r = 0.92) in 40 patients with right ventricular end-diastolic dimension less than 13 mm/m2. Estimates of P in 22 patients with atrial septal defect and right ventricular end-diastolic dimension greater than 13 mm/m2 were fairly good (r = 0.83). It is concluded that echocardiographic measurements of T are useful in diagnosing RVH and in estimating P. 相似文献

The value of 0.1 mV or greater of S-T segment elevation in at least one right precordial lead (V4R to V6R) in defining right ventricular myocardial infarction was assessed prospectively in 43 subjects (33 consecutive patients with enzymatically confirmed infarction of varying type and location, 4 patients with unstable angina and 6 healthy volunteers). Patients with acute myocardial infarction were studied with radionuclide ventriculography and technetium-99m stannous pyrophosphate myocardial scintigraphy 18.2 ± 14.3 (mean ± standard deviation) and 85.1 ± 18.0 hours after the onset of symptoms, respectively. Eleven patients (Group A: 9 patients with transmural inferior infarction, 1 with transmural inferolateral infarction and 1 with transmural anteroseptal infarction) demonstrated right precordial S-T segment elevation and 22 patients (Group B: 6 patients with transmural inferior infarction, 2 with transmural posterior infarction, 3 with transmural inferolateral infarction, 3 with transmural anteroseptal infarction, 3 with transmural extensive anterior infarction, 4 with subendocardial anterior infarction and 1 with unclassified infarction) did not. Right ventricular ejection fraction was significantly lower in Group A (0.47 ± 0.11) than in Group B (0.60 ± 0.12) (p < 0.01). Right ventricular total wall motion score was 63.8 ± 15.6 percent of normal in Group A versus 94.3 ± 8.5 percent in Group B (p < 0.001). Technetium-99m pyrophosphate uptake (2+ or greater) over the right ventricle occurred in nine patients (81.8 percent) in Group A and in one patient (4.5 percent) in Group B (p < 0.001). No patient with unstable angina and no healthy volunteer had S-T segment elevation in a right precordial lead. S-T segment elevation of 0.1 mV or greater in one or more of leads V4R to V6R is both highly sensitive (90 percent) and specific (91 percent) in identifying acute right ventricular infarction. 相似文献

Initial report of percutaneous right ventricular assist for right ventricular shock secondary to right ventricular infarction. 总被引:1,自引:0,他引:1

A 57-year-old female suffered an acute inferior ST segment elevation myocardial infarction. The patient failed thrombolysis and was urgently transferred for rescue percutaneous coronary intervention of the right coronary artery. She decompensated after reperfusion of the occluded RCA and developed cardiogenic shock from severe right heart failure refractory to IABP support and maximal pressors. A percutaneous right ventricular assist device was successfully implanted, which improved mean arterial pressure to a viable range and allowed withdrawal of inotropic medications.Right ventricular failure after infarction remains difficult to manage and has a high mortality. Intraaortic balloon pump and LVAD support have not proven beneficial in cardiogenic shock secondary to RV infarction. This is a report of the first insertion of a percutaneous right ventricular assist device for right ventricular support in a human. Further evaluation is warranted to evaluate the potential benefits of such a device as well as optimal timing of initiation of RV support. 相似文献
