Atraumatic osteonecrosis has been associated with a variety of clinical conditions including corticosteroid usage, alcoholism, infections, hyperbaric events, storage disorders, marrow-infiltrating diseases, coagulation defects, and some autoimmune diseases. Osteonecrosis due to thrombophilia is an extremely rare condition with only few cases reported previously in the literature. Hormone-replacement therapies cause increased risk of venous thrombosis, probably by causing a synergistic effect with inherited clotting defects. In this article, we report a young female with Turner syndrome, who developed avascular necrosis of the femoral head during treatment with oral estrogen, which was associated with low protein S levels.

Percutaneous coronary interventions (PCI) of thrombus-containing lesions are associated with increased risk of complications such as distal coronary embolisation and impaired coronary circulation. Although the use of thrombectomy devices to aspirate thrombus during primary PCI is currently not routinely recommended, there is growing evidence suggesting the use of thrombus aspiration catheters during PCI. Here, we report the case of a 70 year-old patient undergoing thrombus aspiration therapy because of the development of coronary bifurcation macroemboli during initial phase of primary PCI. After successful thrombus aspiration therapy, dramatic improvements in both coronary flow and ST-segment resolution were achieved. Copyright © Polskie Towarzystwo Kardiologiczne.

Myxomas are the commonest cardiac tumours and are usually localised in the atria. Neovascularisation in cardiac myxomas has been shown in previous case reports. However, the clinical importance of neovascularisation in cardiac myxomas is not well understood. In our case report, we present a right atrial myxoma in a 46 year-old woman admitted to our hospital with exertional angina and dyspnea. Coronary angiography revealed the presence of tumour neovascularisation from the right coronary artery, with no evidence of coronary artery stenosis. We thus speculate that neovascularisation of myxoma may cause typical anginal symptoms as a result of coronary steal phenomenon. Coronary angiography might help in the evaluation of the neovascularisation process and also in indicating surgery. Copyright © Polskie Towarzystwo Kardiologiczne.

Background Obstructive sleep apnea (OSA) has been shown to be associated with atrial fibrillation (AF). Prolongation of inter- and intraatrial conduction times during sinus rhythm has also been shown to be related to AF generation. Nasal continuous positive airway pressure (CPAP) is an effective treatment modality of OSA. Methods Twenty-four OSA patients diagnosed through polysomnography and 18 controls were included in the study. The basal inter- and intraatrial electromechanic delays prior to onset of the therapy were measured using tissue Doppler imaging. P-wave dispersion (Pd) was calculated on the basis of 12-lead electrocardiography. Same measurements were performed in OSA patients 6 months after the initiation of the therapy. Results Interatrial (39.2 ± 8 vs. 21.1 ± 2.8 ms, P < 0.001), left intraatrial (20.5 ± 7.2 vs. 11.1 ± 2 ms, P = 0.003), and right intraatrial electromechanical delays (20.7 ± 11 vs. 10 ± 2.6 ms, P < 0.001) prior to CPAP therapy were found to be significantly greater in OSA group as compared with the controls. Pd was also greater in the OSA group as compared with the controls (44 ± 7 vs. 28.5 ± 4 ms, P < 0.001). However, significant improvement has been noted after 6 months of CPAP therapy in interatrial (P < 0.0001), left intraatrial (P = 0.002), and right intraatrial electromechanical delays (P < 0.0001) as well as in Pd (P < 0.0001) as compared to baseline values in patients with OSA. Conclusion Our findings suggested that CPAP therapy provides more homogenous conduction through atria in patients with OSA. This effect may translate into decreased risk for AF associated with OSA. ©2013 Wiley Periodicals, Inc.

Hydatid cysts are a serious health problem in many countries that raise farm animals, and they usually involve the liver and lungs. Although cardiac involvement is a rare manifestation of hydatid cyst disease, its early diagnosis and surgical management are crucial. Patients with cardiac hydatidosis may develop acute life-threatening complications secondary to their invasion of surrounding cardiac structures, such as cyst rupture together with systemic and pulmonary dissemination. Therefore, surgical excision is the definitive method of treatment for cardiac hydatid cysts in order to prevent these potential life-threatening complications, even for asymptomatic patients. Herein, we report the case of a 36-year-old man who initially presented with pleuritic chest pain, hemoptysis, and dyspnea. This was followed by the revelation of multiple cardiopericardial hydatid cysts which were discovered via transesophageal echocardiography and multislice computed tomography. In this case, there was a higher risk of cyst rupture and thromboembolism during systemic and pulmonary circulation due to the invasive nature of the cysts which were located in the left atrium as well as between the pulmonary artery and aorta. The patient successfully underwent the removal of the multiple cardiac cysts under cardiopulmonary bypass by taking into account their relationship with the surrounding cardiac structures and the potential risk of local, systemic, and pulmonary dissemination. A pathological evaluation of the surgical specimens confirmed the diagnosis of cardiac echinococcosis and the aggressive nature of the cardiopericardial hydatid cysts by demonstrating their myocardial invasion. © 2013 Urban & Vogel.
