Maltepe Universitesi Tip Fakültesi, Istanbul, Turkey; Gürol, Tayfun, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Daǧdeviren, Bahadïr, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, TurkeyBackground Potential interference between implanted cardiac devices and other medical instruments is an important concern. Therefore, we aimed to investigate the possible device interaction between implantable cardioverter defibrillators (ICDs) and external enhanced counterpulsation (EECP) treatment. Methods Twenty-one patients with an implanted ICD or cardiac resynchronization therapy with defibrillator (CRT-D) were enrolled into the study. EECP had applied as two sessions of 5 minutes. Data from device interrogations before and after the first EECP session and during second EECP session were recorded and analyzed for signs of possible device interaction. Results There was no sign of inappropriate sensing or noise during EECP session. There was no difference regarding electrode impedance, pacing, and sensing values before and after EECP. There was a statistically significant difference regarding heart rates during EECP therapy between rate response off and on modes (68.69 ± 5.92 beats/min and 90.32 ± 11.05 beats/min, respectively P = 0,001). In four patients with CRT-D and unipolar left ventricular pacing, counterpulsation could not be done because of QRS sensing problems. Conclusions EECP seems to be a safe treatment modality in patients with implanted ICD and CRT-D devices. It should be kept in mind that in those patients with CRT-D, rate responsive mode is on, inappropriate sinus tachycardia can be seen during EECP therapy. Also in patients with CRT-D using a unipolar sensing mode, problems of QRS complex sensing by the EECP may occur and, therefore, this effects synchronization and success of EECP therapy. ©2013, The Authors.

Here we present two cases with haemodynamically significant intermittent functional mitral regurgitation as the underlying mechanism of heart failure. The cases underline the importance of a high index of suspicion in patients with intermittent heart failure, and a careful analysis of echocardiographic images with simultaneous ECG, in order to delineate systolic and diastolic mitral regurgitation. © 2017 Elsevier B.V., All rights reserved.Publication Metadata only Are biventricular systolic functions impaired in patient with coronoray slow flow? A prospective study with three dimensional speckle tracking(Springer Netherlands, 2017) Kemaloglu-Oz, Tuǧba Kemaloʇlu; Eren, Mehmet Ali; Atasoy, Işıl; Gürol, Tayfun; Soylu, Özer; Daǧdeviren, Bahadïr; Kemaloglu-Oz, Tuǧba Kemaloʇlu, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Eren, Mehmet Ali, Department of Cardiology, Siyami Ersek Thoracic and Cardiovascular Surgery Center, Istanbul, Turkey; Atasoy, Işıl, Department of Cardiology, Siyami Ersek Thoracic and Cardiovascular Surgery Center, Istanbul, Turkey; Gürol, Tayfun, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Soylu, Özer, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Daǧdeviren, Bahadïr, Department of Cardiology, Bahçeşehir Üniversitesi, Istanbul, TurkeyThe newly developed three dimensional speckle-tracking echocardiography (3D-STE) technology provides quick and comprehensive quantitative assessment of biventricular myocardial dynamics. The impact of coronary slow flow phenomenon (CSFP) on biventricular functions has not been comprehensively evaluated using this new technology. Therefore, the aim of this study was to evaluate the effects of CSFP on biventricular systolic functions using 3D-STE. Forty patients with CSFP and otherwise normal coronary arteries (NCAs) and 40 age- and sex-matched controls with normal coronary angiograms (CAGs) were prospectively enrolled. Biventricular systolic function was evaluated by 3D-STE. Left ventricular (LV) global longitudinal, circumferential and radial strains, ejection fraction (EF) were significantly lower and LV end-systolic volume (ESV) was significantly higher in the CSFP group compared to the control group. There were no significant differences in LV mass, LV end-diastolic volume (EDV) or LV stroke volume (SV). Additionally, Right ventricular (RV) free wall, septal wall and global longitudinal strains, and RV EF were significantly lower in the CSFP group, but there were no significant differences in RV EDV, ESV and RV SV. The present study demonstrated that CSFP has a notable negative effect on not only 3D strain parameters but also biventricular EF. There was a strong correlation between the strain parameters of the affected vessel’s myocardial area and the TIMI frame count of same vessel. © 2017 Elsevier B.V., All rights reserved.Publication Metadata only Usefulness of live/real time three/four-dimensional transesophageal echocardiography in the percutaneous closure of an iatrogenic aorto-right ventricular fistula(Blackwell Publishing Inc.

The most common treatment is surgical closure of the fistula, but percutaneous closure of the fistula has become an attractive alternative option. We present a case of successful utilization of live/real time three/four-dimensional transoesophageal echocardiography (3/4DTEE) to select the correct device size for percutaneous closure of an adult patient presenting with an aorto-right ventricular (AO-RV) fistula following aortic valve replacement. To the best of our knowledge, this is the first case in which 3/4DTEE was used to select the device size and guide percutaneous closure of an iatrogenic AO-RV fistula. © 2018 Elsevier B.V., All rights reserved.
