RESUMEN

<p><b>OBJECTIVE</b>To summarize the clinical characteristics and treatment experience of patients with non-myxomas primary cardiac tumors accompanied with refractory ventricular tachycardia (VT).</p><p><b>METHODS</b>Clinical and imaging data as well as therapy efficacy and outcome were analyzed in 10 patients with non-myxomas primary cardiac tumors accompanied with refractory VT.</p><p><b>RESULTS</b>There were 5 male and 5 female patients in this cohort [mean age (37.6±18.2) years]. Palpitation was presented in all 10 patients, 7 patients experienced syncope, and 2 patients suffered from amaurosis. The diagnosis was made by combined use of transthoracic echocardiograms, MRI, and CT scan. The time from symptom to diagnosis was (33.2±36.7) months. Symptom-related VT was documented by ECG or Holter monitoring. MRI suggested lipoma in 7 patients, lymphoma in 1 patient and fibroma in another patient. Seven tumors were located in the left ventricle, 1 in right atria, 1 at peri-aortic root and 1 near right ventricular outflow tract. Nine out of 10 patients received anti-arrhythmic drug therapy. The ventricular tachyarrhythmia disappeared after surgical tumor resection in 4 patients. All other patients who were treated with antiarrhythmic drugs, radiofrequency ablation or subtotal excision showed only suboptimal efficacy during (39.4±25.1) months follow-up.</p><p><b>CONCLUSION</b>Surgical tumor removal is the best treatment strategy for the treatment of refractory ventricular tachycardia in patients with primary cardiac benign tumors.</p>

RESUMEN

<p><b>OBJECTIVE</b>To summarize the clinical characteristics and outcome of patients with long-QT syndrome (LQTs) accompanied with torsade de pointes.</p><p><b>METHODS</b>Thirty-two eligible patients were included in this study. Clinical and electrocardiographic data were analyzed and telephone or out-patient follow-up were made in all patients.</p><p><b>RESULTS</b>There were 15 patients with inherited LQTs (h-LQTs) and 17 patients with acquired LQTs (a-LQTs). There are more women (n = 24) than men (n = 8). β blockers, potassium and magnesium supplement were the basic therapy for h-LQTs patients, bivent pacemaker was implanted in 2 patients and implantable cardioverter defibrillator was implanted in 5 patients. Ventricular tachyarrhythmias and syncope occurred in 4 patients during (39.4 ± 25.1) months follow-up. In 17 a-LQTs patients, one patient with dilated cardiomyopathy died suddenly and another patient with implanted cardioverter defibrillator experienced one ventricular tachycardia during (30.9 ± 13.3) months follow-up.</p><p><b>CONCLUSIONS</b>The prognosis in h-LQTs and a-LQTs patients with structure heart disease is poor. ICD or CRT-D therapy is suggestive for a-LQTs patients with structure heart disease.</p>
