Giant pericardial cyst with a growing feature
(Medknow Publications, 2018) Çetin,S.; Heper,G.; Vural,M.; Hazirolan,T.; Tanrikulu,F.; Gülhan,E.
Pericardial cysts are rare and benign lesions of the heart. They are usually asymptomatic and diagnosed incidentally on echocardiography or chest X-ray. In this report, we present an extremely rare case of a symptomatic giant pericardial cyst (11.6 cm × 10.6 cm × 8 cm) of a 55-year-old male patient who was admitted to our cardiology clinic. A thoracic computed tomography (CT) in 2013 revealed a giant pericardial cyst. However, at that time, the patient was asymptomatic and follow-up was recommended. Recent thoracic CT and magnetic resonance imaging demonstrated a significantly growing feature of this cyst with impending possible complications. © 2018 Nigerian Journal of Clinical Practice | Published by Wolters Kluwer - Medknow.

Left atrial remodelling may predict exercise capacity in obstructive sleep apnoea patients
(Taylor and Francis Ltd., 2018) Çetin,S.; Vural,M.; Akdemir,R.; Fırat,H.
Background: Left atrial volume (LAV) and LA deformation has been proposed as a good marker of exercise performance in patients with diastolic dysfunction (DD). As DD is more prevalent in obstructive sleep apnoea (OSA) we aimed to evaluate the influence of LAV and LA deformation parameters on exercise performance in varying severity of OSA. Materials and methods: OSA was diagnosed after polysomnography. Fifty-five OSA patients were enrolled in the study. OSA patients were divided into two groups with apnoea-hypopna-index (AHI) > 30 and <30. LAV was calculated. LA strain and LA strain rates were assessed with speckle tracking echocardiography (STE). Exercise capacity was evaluated by treadmill exercise test. Results: MET values were lower in group II compared to group I (p <.05). Echocardiographic findings: Comparison within groups: In both groups E/E’, LA stain, LA strain rate S and LA strain rate E were higher after exercise than before (p <.05). In group I LA strain rate A was higher after exercise than before (p <.05). Comparison between groups: LA strain, LA strain rate S, LA strain rate E and LA strain rate A were lower and E/E’ and LAVI were higher in group II compared to group I before and after exercise (p <.05). Correlation with METs: AHI, LVEDV, E/E’ and LAVI were negatively and LA strain was positively correlated with METs (p <.05). Conclusions: Left ventricular diastolic dysfunction is more prevalent in severe OSA and is associated with impaired exercise performance. Additionally, LA remodelling may predict exercise capacity in this subgroup of patients. © 2017, © 2017 Belgian Society of Cardiology.
