Isolated left ventricular noncompaction is an inherited cardiomyopathy characterized by multiple prominent trabeculations with deep intertrabecular recesses. The diagnosis is often missed because echocardiography poses inherent problems of poor echo window in assessment of the LV apex, which is most commonly involved in noncompaction. We report a case in which conventional 2D echocardiography failed to demonstrate multiple prominent trabeculations. Contrast echocardiography confirmed the presence of multiple trabeculations with deep intertrabecular recesses. This report emphasizes the importance of contrast echocardiography in the diagnosis of ventricular noncompaction. 相似文献

Idiopathic ventricular tachycardias (VTs) are generally divided into those arising from the right ventricle and those arising from the left ventricle. There has been few reports of two morphologically distinct VT occurring in patients with no apparent structural heart disease. We report a patient with verapamil-sensitive left VT with a right bundle branch block pattern that spontaneously changed to VT with a left bundle branch block pattern. Ventricular fibrillation was induced by the application of programmed stimulation. Although it is unclear if our patient with pleomorphic VT has ventricular vulnerability, it is necessary to investigate further and follow him carefully. 相似文献

A technique of direct mechanical ventricular assistance (DMVA) has been available since 1966. Ventricular assistance is provided by a glass cup lined with a Silastic diaphragm. It is held on the cardiac ventricles by suction. Alternating positive and negative pressure in the space between the cup and the diaphragm provides a pumping mechanism for blood flow. DMVA was compared to closed chest massage (CCM) and open chest massage (OCM) during ventricular fibrillation in six dogs. Each technique was applied for 10 minutes. Three dogs had CCM followed by OCM and then DMVA. Three dogs had only OCM and DMVA. Blood pressure and cardiac output were measured. All variables were calculated as a percentage of pre-ventricular-fibrillation values. Mean blood pressure was 19.7% with CCM, 39.8% with OCM, and 55.1% with DMVA. Systolic blood pressure was 25.8% with CCM, 51.9% with OCM, and 64.0% with DMVA. Diastolic blood pressure was 17.3% with CCM, 37.3% with OCM, and 48.9% with DMVA. Cardiac output was 13.8% with CCM, 37.1% with OCM, and 58.0% with DMVA. For each variable, OCM produced statistically higher values than did CCM. DMVA produced statistically higher values than did OCM for all variables. These preliminary results suggest that DMVA may be superior to currently available methods of cardiac massage during ventricular fibrillation. 相似文献

Congenital ventricular diverticula are rare. Clinically, they may be asymptomatic or cause systemic embolization, heart failure, valvular regurgitation, ventricular rupture, ventricular arrhythmia, or sudden death. We report the case of a 56-year-old woman with sustained ventricular tachycardia, who, during investigation, was diagnosed with a diverticulum in the inferobasal portion of the left ventricle. The clinical characteristics and treatment of this rare disease are discussed. 相似文献

Right ventricular (RV) involvement commonly occurs in patients with acute inferior myocardial infarction and is associated with high mortality and morbidity. RV dysfunction and dilatation commonly recover in survivors; chronic RV dyskinesia and failure are rare complications. This case report presents a patient in whom an isolated RV aneurysm complicates a RV involvement of acute inferior-posterior myocardial infarction. 相似文献

射频消融治疗室性早搏触发特发性室性心动过速/心室颤动的病例分析 总被引:1,自引:0,他引:1
目的探讨射频消融治疗在室性早搏(室早)触发特发性室性心动过速/心室颤动(室速/室颤)中的作用。方法总结3例由室早触发室速/室颤的治疗经验,1例对室早进行射频消融(RF—CA)并植入心律转复除颤器(ICD),另1例经射频消融未完全消除室早而选择植入ICD,第3例经射频消融成功消除室早,未再发室颤。结果随访2年,3例患者均存活,ICD未再记录到室速/室颤。结论在室早触发室速/室颤病例中,应分析室早与室速/室颤的相关性,给予个体化治疗,射频消融室早可以消除/减少晕厥和室颤的发作。 相似文献
