RESUMO
BACKGROUND: Isolated left upper partial anomalous pulmonary venous connection (PAPVC) via the innominate vein to the right atrium is a rare congenital anomaly. This study was undertaken to determine the efficacy of a modified suprasternal view in transthoracic echocardiography (TTE) for the detection of left upper PAPVC. METHODS: After the incidental diagnosis of left upper PAPVC in our first patient in 2008, we added a modified suprasternal view to all TTEs performed in our pediatric cardiology clinic. This was obtained by tilting the tail of the probe 30-450 towards the right shoulder of the patient during suprasternal long axis view for a better visualization of the innominate vein. RESULTS: Among 7200 patients who underwent TTEs between 2008 and 2020, we identified 13 patients with left upper PAPVC into the innominate vein. All were asymptomatic children with normal cardiac chambers and no accompanying congenital disorders. In 10 cases, diagnoses were confirmed by multi-slice computerized tomography, whereas one patient underwent catheterization for confirmation. CONCLUSION: Isolated left upper PAPVC to the innominate vein is a rare congenital disorder that can be present in asymptomatic children with normal cardiac chambers. TTE, with a modified approach in suprasternal long axis view, has a high diagnostic value in the detection of this condition.

Takotsubo cardiomypathy is a very rare cardiovascular syndrome leading to myocardial infarction and left ventricular dysfunction in the absence of a detectable coronary artery lesion. It is accepted as reversible left ventricular asynergy occuring typically after an intrinsic adrenergic hyperstimulation. In this report we present Takotsubo cardiomyopathy in a 75-year-old patient with multiple autoimmune disorders.
RESUMO
Vegetative electrode infection following permanent pacemaker implantation is a rare and serious complication. Among 1920 patients who underwent permanent pacemaker implantation in our institute between 1980 and 2000, 7 patients aged 65 to 78 years were diagnosed to have pacemaker related endocarditis. In this study, the clinical course and management strategies for these patients are reviewed. The most frequently encountered factors contributing to development of pacemaker infection were local complications such as postoperative hematoma and inflammation, and recurrent surgical interventions on the pacemaker system. In blood cultures S. aureus was the most common causative microorganism. Echocardiography could be performed in 5 patients. Three patients were referred to open-heart surgery for total removal of the pacemaker system, and one patient had his pacemaker system removed percutaneously. The remaining 3 patients did not agree to either surgical or percutaneous removal. These patients have been under antibiotic therapy for approximately 3 years and they still do not have any signs of a serious infection. Consequently, in patients with permanent pacemakers, infective endocarditis should be considered in the presence of fever and local symptoms. Blood cultures should be obtained and echocardiography should be performed. Complete removal of the pacemaker system with intensive antibiotic treatment is necessary for complete eradication of the infection. However, if percutaneous or surgical removal of the electrodes cannot be done because of high perioperative risk or the patient does not agree to undergo either method, medical treatment with long term antibiotic use may be considered as an alternative.
