Zhimin Liao, Yaqin Xiong, Linli Luo
A 29-year-old woman at 34 weeks' gestation with uncontrolled hyperthyroidism and thyrotoxic heart disease was admitted to urgency Cesarean section. After preoperative sedation and good communication, low-dose spinal anesthesia (7.5 mg 0.5 % bupivacaine) combined with epidural anesthesia (6 ml 2 % lidocaine) was performed through L3-4 inter-vertebral. Opioids were given intravenously to the mother for sedation after delivery of the baby. Satisfactory anesthesia and sedation was provided during surgery. The mother and the neonate were safe and no special complication was found after surgery...

Thyrotoxicosis-induced cardiomyopathy and consequent heart failure is one of the most grave complications of uncontrolled hyperthyroidism. In such patients, early recognition of thyrotoxicosis, and directed antithyroid therapy can lead to rapid normalization of left ventricular function. Herein, we present a case of a 29-year-old male with Graves' disease who developed heart failure with severe deterioration of left ventricular function and eventually, circulatory collapse. Height and weight of the patient were 1...

Thyrotoxic hypokalemic periodic paralysis (TPP) is a condition characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. We describe two cases of thyrotoxic periodic paralysis who presented to our hospital with potassium values of 1.3 MeQ/l and 1.2 MeQ/l, respectively. Surprisingly, the two patients had no documented past medical history. Based on the clinical features of high heart rate, palpitations (seen in both the patients), and exophthalmos (seen in one patient), thyrotoxic periodic paralysis was suspected...

The most common thyroid diseases during pregnancy are hyper- and hypothyroidism and their variants including isolated hypothyroxinemia (hypo-T4), autoimmune thyroid disease (AITD) and different types of goiter. AITD represents the main cause of hypothyroidism during pregnancy ranging in prevalence between 5 and 20% with an average of 7.8%. The incidence of isolated hypo-T4 is about 150 times higher compared to congenital hypothyroidism. Prevalence of Graves' disease (GD) ranges between 0.1% and 1% and the Transient Gestational Hyperthyroidism Syndrome between 1 and 3%...

INTRODUCTION: Thyrotoxicosis is an endocrine disorder with prominent cardiovascular manifestations. Thyroid hormone acts through genomic and non-genomic mechanisms to regulate cardiac function. Echocardiography is a useful, non-invasive, easily accessible, and affordable tool for studying the structural and physiological function of the heart. AIM: We studied thyrotoxicosis patients in a Nigerian Teaching Hospital and employed trans-thoracic echocardiography to find out if there were abnormalities in the hearts of these patients...

Prenatal ultrasonography of a pregnant woman with a past history of total thyroidectomy for Graves' disease detected fetal tachycardia, fetal growth restriction and oligohydramnios at 30 weeks gestation. Because a high titer of thyroid-stimulating hormone receptor antibody was noted in maternal serum and the fetal goiter was detected on ultrasonography, fetal hyperthyroidism was strongly suspected and subsequently confirmed with cordocentesis at 31 weeks gestation. After treatment of fetal hyperthyroidism through oral maternal administration of methimazole (MMI) starting at 33 weeks gestation, fetal heart rate and amniotic fluid volume returned to normal ranges...

OBJECTIVE: To evaluate clinical symptoms, signs and various forms of thyrotoxicosis, and to assess the thyroid function status at the first 6-week follow-up. METHODS: The retrospective chart review involved thyrotoxic patients presenting at the Endocrine Clinic of Jinnah Postgraduate Medical Centre, Karachi, between April 2007 and January 2011. All hyperthyroid patients were included with the exception of those with suspected or proven malignancy. The records were maintained on a structured proforma and analysed statistically to work out frequencies and percentages...

A 52-year-old woman, who had an out-of-hospital cardiac arrest, was resuscitated, intubated and transferred with cardiogenic shock to angioplasty of the right coronary artery. Afterwards the patient had normal biventricular function, but four days later she developed atrial fibrillation and recurrent cardiogenic shock with a left ventricular ejection fraction of 20%. Thyrotoxic crisis was determined as the underlying cause; and antithyroid treatment stabilised the patient's haemodynamics completely within 24 hours...

Jaundice related to thyrotoxicosis and not as an effect of antithyroid drugs is a rare complication that usually occurs in the presence of heart failure (HF) or hepatitis. We report a case of a 54-year-old white woman with hyperthyroidism caused by Graves's disease and jaundice despite methimazole suspension. Bilirubin fluctuated at high values, between 30.0 and 52.3 mg/dL, transaminases were slightly increased, on admission ALT = 46 U/L and AST = 87 U/L; coagulation indices and serum proteins were on the lower limit of the normal range with PT 68% and albumin = 2...

BACKGROUND: Thyrotoxic periodic paralysis (TPP) is a variant of periodic paralysis (PP) that occurs in patients with underlying mutations in genes for cation channels, if they develop thyrotoxicosis. It is disabling, and fatalities sometimes occur. Here, we present a patient with TPP who developed hypokalemic paralysis that was probably aggravated by the administration of a carbohydrate, probably contributing to, if not causing, a fatal outcome. SUMMARY: A 30-year-old Chinese patient received (131)I treatment for Graves' disease (GD) in our hospital...

Hyperthyroidism is associated with many heart diseases. Thyrotoxic state has a relationship with coronary spasm. We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain. The diagnosis of coronary spasm was confirmed by coronary angiography (CAG). She is treated well with anti-thyrotoxicosis and anti-anginal medication. We recommend not use CAG as the first diagnostic choice among the patients with medication-uncontrolled hyperthyroidism and chest pain.

OBJECTIVE: To review cardiac manifestations in the syndrome of resistance to thyroid hormone (RTH) and to question the general recommendation that the thyroid-stimulating hormone (TSH) value be the guide to thyroid hormone replacement. METHODS: The syndrome of RTH is caused by mutations in the carboxy-terminal portion of the β isoform of the thyroid hormone receptor, resulting in variable clinical manifestations. It is generally recommended that the replacement of thyroid hormone in patients with RTH be guided by the serum TSH concentration...

Monomorphic ventricular tachycardia (VT) is a unique manifestation of hyperthyroidism. We present the case of a 41-year-old male with a history of hyperthyroidism presenting with palpitations secondary to non-sustained episodes of monomorphic VT. Cardiac arrhythmias due to thyrotoxicosis are perpetually supraventricular in origin. Monomorphic VT in the setting of thyrotoxicosis in the absence of structural heart disease is exceedingly rare. After starting propranolol and increasing the dose of methimazole, the patient had no further episodes of VT...

Atrial fibrillation, the most common cardiac complication of hyperthyroidism, occurs in an estimated 10% to 25% of overtly hyperthyroid patients. The prevalence of atrial fibrillation increases with age in the general population and in thyrotoxic patients. Other risk factors for atrial fibrillation in thyrotoxic patients include male sex, ischemic or valvular heart disease, and congestive heart failure. The incidence of arterial embolism or stroke in thyrotoxic atrial fibrillation is less clear. There are many reports of arterial thromboembolism associated with hyperthyroidism, including cases of young adults without coexisting risk factors other than thyrotoxic atrial fibrillation...
