Takayasu arteritis as a cause of arterial hypertension. Case report and literature review

We report a 16-year-old girl in whom Takayasu arteritis (TA) was manifested mainly by severe arterial hypertension on her right arm, which was detected during a routine examination at school. Her systolic blood pressure on the right arm was significantly higher than that on the left one. There was also a pressure difference between the right arm and legs. The pulse of the left external carotid artery and that of the left radial artery was absent. Vascular bruits over interscapular and right supra- and subclavian areas were heard on auscultation. The diagnosis of TA was confirmed by a spiral computed tomography angiography, which showed a thickened thoracic aortic wall and narrowing of its lumen. In addition, complete occlusion of the left common carotid artery and the left subclavian artery was observed. Conclusion: The rarity of the disorder and the heterogeneous nature of its clinical manifestation predispose to a late diagnosis and delayed treatment. Our report highlights the fact that the condition can and does occur in a pediatric population in Europe and hence must be considered in patients presenting with suggestive symptoms and signs, especially in young patients with unexplained hypertension. Clinical suspicion and proper imaging are crucial for the correct diagnosis and management of patients with TA. A brief review of literature completes this report

Total anomalous pulmonary vein drainage in a 60-year-old woman diagnosed in an ECG-gated multidetector computed tomography : a case report and review of literature

Purpose: Total anomalous pulmonary vein drainage (TAPVD) is a congenital cardiac defect in which there is no connection between pulmonary veins and the left atrium. Pulmonary veins form a confluence independent of the left atrium and drain to a systemic vein. TAPVD types are: supracardiac, cardiac, infracardiac, and mixed. TAPVD accounts for approximately 1.5-2.2% of all congenital heart diseases. This anomaly is usually diagnosed in the neonatal period, and it coexists with atrial septal defect. Adult cases of TAPVD are rarely reported. Case report: We report a rare case of a 60-year-old woman with incidentally found, uncorrected TAPVD in ECG-gated multidetector computed tomography. In previous echocardiographic examinations partial anomalous pulmonary venous return and atrial septal defect were diagnosed. Conclusions: ECG-gated multidetector computed tomography is a valuable diagnostic method for adults with congenital heart disease. It enables evaluation of coronary arteries and simultaneously provides detailed anatomy of great vessels

Thoracic ectopic kidney in adults. A report of 2 cases

Thoracic kidney is the rarest, usually asymptomatic type of kidney ectopia. 2 cases of thoracic kidney discovered incidentally through chest radiography are reported. In both patients renal function tests were normal and no further treatment was necessary. Ultrasonography and computed tomography studies performed for confirmation of the diagnosis are presented. An embryonic background of this abnormality is discussed

Acute left main coronary artery occlusion following inadvertent delivery of radiofrequency energy during ventricular tachycardia ablation successfully treated by rescue angioplasty with stenting: A two-year follow-up

Radiofrequency catheter ablation (RFCA) is a treatment mode in patients with recurrent, symptomatic, ventricular arrhythmias. A rare but potentially life-threatening complication of RFCA includes injury to the coronary arteries, which leads to acute occlusion and myocardial infarction. In the few reported cases, the most frequently affected vessel has been the left main coronary artery. We present the case of a 28 year-old female. During the RFCA procedure, an acute occlusion of the left main coronary artery occurred, which was treated successfully with emergency angioplasty

Early brain perfusion improvement after ventriculoperitoneal shunt surgery in patients with idiopathic normal pressure hydrocephalus evaluated by 99mTc-HMPAO SPECT — preliminary report

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) is a clinical syndrome that consists of the triad: gait disturbance, mental deterioration and urinary incontinence associated with normal cerebrospinal fluid pressure (CSF), without pre-existing abnormalities. The most popular treatment option is surgical implantation of a shunt. Brain perfusion increase occurring months or years after successful shunt surgery is well described in the literature. Early improvement of perfusion is not well documented. Therefore, the objective of the present study was to determine patterns of brain perfusion changes 3–6 days after the ventriculoperitoneal shunting in patients with iNPH by using 99mTc-HMPAO SPECT. MATERIAL AND METHODS: Sixteen patients with iNPH (9 women, 7 men, mean age 64.1 ± 12.7 years) who underwent ventriculoperitoneal shunt surgery were included into the study group. Indications for implanting a shunt were based on clinical history, neuroimaging and CSF dynamic studies with an infusion test. Brain perfusion SPECT was performed 1–2 days before and 3–6 days after the surgical treatment. For comparison of perfusion before and after the surgery SPECT scans were assessed visually and semiquantitatively with voxel based analysis. RESULTS: No side effects were observed after the surgery. Brain perfusion improvement after shunting was observed in 10 patients (62.5%). Patterns of perfusion changes varied between patients, with combinations of different bilateral and lateralized brain regions involved. Perfusion increased in the whole brain (3 patients), in the right cerebral hemisphere (1 patient) or in the separate cerebral regions (6 patients): frontal, parietal, temporal, cerebellum, cingulate gyrus. Perfusion improvement was predominantly observed in the frontal lobes: right frontal (3 cases, 18.8%), left frontal (3 cases, 18.8%). CONCLUSIONS: Cerebral perfusion is recovered promptly after ventriculoperitoneal shunt surgery in about 60% of patients with iNPH. This improvement may be global or regional in different cerebral areas with prevalence of the frontal lobes

Complications of permanent cardiac pacing in patients with persistent left superior vena cava

Background: Persistent left superior vena cava (PLSVC) is present in about 0.3–0.5% of the general population and in about 12% of patients with other abnormalities. This congenital anomaly is usually asymptomatic and does not cause any physiological problems. However, it may become a significant problem in multiple clinical situations. Various complications related to PLVSC are encountered in anesthesiological, nephrological, oncological and cardiological procedures. The presence of PLSVC is usually incidentally detected during placement of pacemaker (PM), implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT) leads. Technical difficulties during lead positioning (especially ventricular leads) are commonly known and often described in the literature. The purpose of the present study was to evaluate the specific methods used for implantation of increasingly complicated pacing systems, finding an optimal strategy in patients with PLSVC, especially with electrotherapy complications.Methods: We performed a single-center retrospective analysis of 11 patients (7 women and 4 men, mean age 60.4 ± 13 years) with PLSVC hospitalized in single Cardiology Department between 2000 and 2012. The clinical characteristic, indications for PM/ICD/CRT implantation, technique of implantation and complications were evaluated.Results: In PLSVC patients, different indications for pacing or resynchronization therapy were represented: sick sinus syndrome (SSS) in 4 patients, 3rd degree atrio-ventricular (AV) block in 4 patients, dilated cardiomyopathy with left bundle branch block in 2 patients, dilated cardiomyopathy and non-sustained ventricular tachycardia episodes in 1 patient. In patients no. 1, 3, 4 and 10 the complications necessitated the change of leads or type of pacing. Transvenous lead extraction was successfully performed in patient no. 1 and 10 with re-implantation of new leads via PLSVC in patient no. 1 and via right superior vena cava in patient no. 10. Patient no. 3 received an additional ventricular lead via PLSVC because of 2nd degree AV block (formerly atrial lead implanted due to SSS). In patient no. 4 with left atrial pacing (lead in coronary sinus), prosthetic mitral valve replacement was combined with epicardial ventricular lead placement. Patients no. 2 and 7 received a CRT device, without technical problems in patient no. 7, whereas in patient no. 2 due to difficulties with left ventricular lead positioning a hybrid approach to epicardial lead pacing was used. In patient no. 8 an ICD was implanted with difficulty in placing defibrillator lead. Patient no. 5 received 2 atrial leads via PLSVC with successful biatrial pacing; patient no. 6 with the necessity of DDD pacing had a (ventricular) lead for left atrial pacing and a typical right ventricular lead. In patients no. 9 and 11 typical DDD pacing was used with contralateral placement of the leads due to anatomical and technical differences. After 12 years of follow-up the survival is 90.9%. Late electrotherapy complications have developed only in patient no. 8 (problems with the defibrillator lead).Conclusions: Patients with PLSVC are a very heterogeneous group with different indications for pacing, therefore individualization of therapy is required. Technical complications connected with pacing of the right heart chambers are commonly known, hence transvenous left atrialor left ventricular lead implantation should be attempted. In case of difficulties in transvenous positioning of the lead, a hybrid or isolated cardiac surgery technique should be considered. Because of the increasing number of electrotherapy complications, these problems are also present in PLSVC patients. Transvenous lead extraction with re-implantation of a pacing system has not been reported yet. For this reason a thorough evaluation of the venous system is required in PLSVC patients before intervention.

Superior vena caval syndrome caused by the tumor of the left hilum in a patient with unilateral persistent left superior vena cava diagnosed with multislice spiral computed tomography : a case report

Background: Unilateral persistent left superior vena cava (PLSVC) is an infrequent finding with incidence of 18-20% among the individuals with PLSVC. The persistence of the left-sided superior vena cava is an effect of disturbances in development of the connection between the precardinal veins (anterior cardinal veins) and formation of the sinus venosus in early stages of embryogenesis. Case report: The paper presents a case of a 62-year-old patient with a mass lesion of the left hilum, which caused left-sided superior vena caval syndrome in the presence of unilateral PLSVC. Conclusions: Developmental mechanisms of superior vena caval syndrome are discussed. The evolution of changes related to infiltration and occlusion of PLSVC is shown on the basis of three selected MSCT examinations

Primary cardiac tumours are very rare (0.02%). Typically fibroelastoma arises from valvular endocardium, nonvalvular locations occur occasionally. Usually fibroelastoma is asymptomatic, however in some cases it may produce small superficial thrombi with substantial risk of embolisation. We report 59 year-old male with left atrial appendage location of papillary fibroelastoma diagnosed during transesophageal echocardiography. Computed tomography confirmed morphological signs typical for this tumour. Kardiol Pol 2011; 69, 3: 284-28
