Öğe Assessment of a trial electromechanical delay in patients with mitral valve prolapse(2011) Acikgoz N.; Yagmur J.; Ermis N.; Cansel M.; Atas H.; Tasolar H.; Pekdemir H.Atrial arrhythmias are seen frequently in symptomatic patients with mitral valve prolapse (MVP). The purpose of our study was to evaluate whether the atrial electromechanical delay (AEMD) measured by tissue Doppler imaging (TDI) is prolonged in patients with MVP. A total of 40 patients with MVP (16 males/24 females, 33.4 ± 6.1 years), and 40 controls (18 males/22 females, 34.2 ± 4.2 years) were included in the study. Inter-AEMD and intra- AEMD were measured by TDI. P-wave dispersion (PWD) was calculated from the 12-lead electrocardiogram. Inter-AEMD and intra-AEMD were significantly longer in patients with MVP than in the controls (31.6 ± 12.1 vs 24.7 ± 5.4 ms, p = 0.001 and 8.1 ± 5.3 vs. 5.7 ± 1.9 ms, p = 0.008; respectively). PWD was significantly longer in patients with MVP than in the controls (41.3 ± 7.1 vs 34.7 ± 4.3 ms, p<0.0001). The left atrial (LA) diameter, anterior and posterior mitral leaflet thicknesses were significantly higher in patients with MVP than in the controls. (35.4 ± 3.0 vs 31.9 ± 3.0 mm, p<0.0001 and 3.6 ± 0.9 vs 2.8 ± 0.7 mm, p<0.0001 and 2.9 ± 0.7 vs 2.2 ± 0.4 mm p<0.0001; respectively). Inter-AEMD was positively correlated with PWD, mitral leaflet thickening and LA diameter. We showed that AEMD is significantly prolonged in patients with MVP, and speculated that this prolongation may reflect the increase of the risk of atrial arrhythmias in MVP subjects. © 2011 Academic Journals.Öğe A rare and avoidable complication of percutaneous coronary intervention: Stent trapped in the left main coronary artery and its unusual treatment(2011) Çiçek D.; Pekdemir H.Entrapment of catheter components during cardiac interventions is rare but can cause life-threatening complications and sometimes requires emergency surgical treatment. This case study describes a 52-year-old male who had unstable angina pectoris and underwent stent insertion into the left circumflex artery. Unfortunately, the coronary stent and the balloon catheter were trapped while crossing the angulated segment between the left circumflex and left main coronary artery. The stent catheter was removed by an unusual transcatheter approach. The interventional cardiologist should keep in mind that angulated segments may reduce the successful rate of coronary stenting and contribute to the stent entrapment complication.Öğe RE: Mean platelet volume in patients with idiopathic and ischemic cardiomyopathy(2013) Açikgöz N.; Ermiş N.; Ya?mur J.; Cansel M.; Ataş H.; Pekdemir H.; Özdemir R.[No abstract available]
