Öğe Acute myocardial infarction shortly after valve-in-valve transcatheter aortic valve implantation successfully managed with challenging percutaneous coronary intervention(Turkish Soc Cardiology, 2018) Yalta, Kenan; Kaya, Caglar; Aksoy, Yuksel; Yilmaztepe, Mustafa; Kardas, FatihIn recent years, transcatheter aortic valve implantation (TAVI) has been considered a novel option for the management of surgically high-risk patients requiring aortic valve replacement. Presently described is a case of acute coronary syndrome (ACS) managed with a challenging primary percutaneous coronary intervention (PCI) shortly after a valve-in-valve TAVI intervention. This case highlights 2 important issues: PCI may be an option for the management of coronary heart disease in patients after TAVI even in the setting of demanding features associated with coronary osteal engagement, and secondly, TAVI may serve as a potential risk factor for future coronary ischemic syndromes, largely due to its potential adverse effects on coronary flow dynamics, etc. However, the latter notion is quite speculative, and should be tested in further studies.Öğe Arrhythmias following Revascularization Procedures in the Course of Acute Myocardial Infarction: Are They Indicators of Reperfusion or Ongoing Ischemia?(Hindawi Ltd, 2013) Tatli, Ersan; Alicik, Guray; Buturak, Ali; Yilmaztepe, Mustafa; Aktoz, MeryemObjective. The most important step in the treatment of ST elevation myocardial infarction is to sustain myocardial blood supply as soon as possible. The two main treatment methods used today to provide myocardial reperfusion are thrombolytic therapy and percutaneous coronary intervention. In our study, reperfusion arrhythmias were investigated as if they are indicators of coronary artery patency or ongoing ischemia after revascularization. Methods. 151 patients with a diagnosis of acute ST elevation myocardial infarction were investigated. 54 patients underwent primary percutaneous coronary intervention and 97 patients were treated with thrombolytic therapy. The frequency of reperfusion arrythmias following revascularization procedures in the first 48 hours after admission was examined. The relation between reperfusion arrhythmias, ST segment regression, coronary artery patency, and infarct related artery documented by angiography were analyzed. Results. There was no statistically significant difference between the two groups in the frequency of reperfusion arrhythmias (P = 0.355). Although angiographic vessel patency was higher in patients undergoing percutaneous coronary intervention, there was no significant difference between the patency rates of each group with and without reperfusion arrythmias. Conclusion. Our study suggests that recorded arrhythmias following different revascularization procedures in acute ST elevation myocardial infarction may not always indicate vessel patency and reperfusion. Ongoing vascular occlusion and ischemia may lead to various arrhythmias which may not be distinguished from reperfusion arrhythmias.Öğe Assessment of ventricular and left atrial mechanical functions, atrial electromechanical delay and P wave dispersion in patients with scleroderma(Via Medica, 2011) Aktoz, Meryem; Yilmaztepe, Mustafa; Tatli, Ersan; Turan, Fatma Nesrin; Umit, Elif G.; Altun, ArmaganBackground: The aim of this study was to investigate ventricular functions and left atrial (LA) mechanical functions, atrial electromechanical coupling, and P wave dispersion in scleroderma patients. Methods: Twenty-six patients with scleroderma and twenty-four controls were included. Left and right ventricular (LV and RV) functions were evaluated using conventional echocardiography and tissue Doppler imaging (TDI). LA volumes were measured using the biplane area-length method and LA mechanical function parameters were calculated. Inter-intraatrial electromechanical delays were measured by TDI. P wave dispersion was calculated by 12-lead electrocardiograms. Results: LV myocardial performance indices (MPI) and RV MPI were higher in patients with scleroderma (p = 0.000, p = 0.000, respectively) while LA passive emptying fraction was decreased and LA active emptying fraction was increased (p = 0.051, p = 0.000, respectively). P wave dispersion and inter-intraatrial electromechanical delay were significantly higher in patients with scleroderma (25 [10-60] vs 20[0-30], p = 0.000, 16.50 [7.28-26.38] vs 9.44 [3.79-15.78] and 11.33 [4.88-16.06] vs 4.00 [0-12.90], p < 0.05, respectively). Interatrial electromechanical delay was negatively correlated with LV E wave, (p = 0.018). LV E wave was demonstrated to be a factor independent of the interatrial electromechanical delay (R(2) = 0.270, beta = -0.52, p = 0.013). Conclusions: This study showed that in scleroderma patients, global functions of LV, RV and mechanical functions of LA were impaired, intra-interatrial electromechanical delays were prolonged and P wave dispersion was higher. LV E wave was demonstrated to be a factor that is independent of the interatrial electromechanical delay. Reduced LV E wave may also give additional information on the process of risk stratification of atrial fibrillation.

Reply(Aves Yayincilik, 2009) Tatli, Ersan; Aktoz, Meryem; Aydin, Goekhan; Yilmaztepe, Mustafa; Altun, Armagan[Abstract Not Available]Öğe The effect of cold stress on right ventricular function in patients with systemic sclerosis(Marmara Univ, Fac Medicine, 2018) Yilmaztepe, Mustafa; Aktoz, Meryem; Tatli, Ersan; Altun, ArmaganObjective: Pulmonary hypertension and right heart failure are poor prognostic factors in systemic sclerosis (SSc). The effect of cold stress on pulmonary vasospasm was evaluated in some trials but the results were conflicting. The aim of our study was to determine the effect of cold stress on right ventricular (RV) function. Materials and Methods: Twenty-four patients with SSc and 24 age and sex-matched healthy controls were enrolled in the study. Transthoracic echocardiography (TIE) was performed to all patients at rest and after peripheral cold exposure. Baseline and after cold stress test TIE results were compared between the groups. Results: Cold exposure induced changes in particularly right venticular function. Pulmonary acceleration time was significantly shortened in the SSc group (118.8 +/- 11.7ms vs 111.3 +/- 13.7ms, P<0.001). Tricuspid annular plane systolic excurison and RV fractional area change were also decreased after cold exposure in the SSc group. (23.3 +/- 1.6mm vs 21.9 +/- 1.9 mm, P<0.001; 46.3 +/- 5.8 vs 44.4 +/- 5.8,P= 0.007, consecutively). Left ventricular (LV) function did not change after cold stress (LV myocardial performance index (0.42 +/- 0.04 vs 0.42 +/- 0.05), P=0.748). Conclusion: Peripheral cold exposure caused a reduction in right ventricular function indicating pulmonary Raynaud's phenomenon as a possible contributing factor.Öğe Ictal Asystole in a Patient with Right Temporal Lobe Epilepsy(Taiwan Soc Cardiology, 2022) Kaya, Caglar; Ozkan, Hulya; Yilmaztepe, Mustafa; Aksoy, Yuksel; Baysal-Kirac, Leyla; Gurses, Candan[Abstract Not Available]Öğe Is abnormality of double right coronary artery seen more frequently in Turkey than the others?(Elsevier Ireland Ltd, 2008) Tatli, Ersan; Buyuklu, Mutlu; Altun, Armagan; Yilmaztepe, Mustafa[Abstract Not Available]Öğe Late coronary ischemic syndromes associated with transcatheter aortic valve implantation: A review of mechanistic and clinical aspects(Elsevier, 2018) Yalta, Kenan; Zorkun, Cafer; Yilmaztepe, Mustafa; Gurlertop, YektaIn the past years, transcatheter aortic valve implantation (TAVI) has emerged as a promising option for the treatment of aortic valve pathologies particularly in the the presence of surgically high-risk situations. Importantly, a variety of specific procedural complications including acute coronary osteal occlusion, though very rare, has been reported in major clinical studies. However, little is known about the late impact of TAVI on coronary system at the macro and microvascular levels. On the other hand, clinical studies as well as real life experiences have shown variable rates of acute coronary syndrome (ACS) readmissions among TAVI recipients in the short and long terms. Within this context, it may be suggested that even though late coronary ischemic events arising after TAVI, to some extent, appears to be spontaneous or attributable to certain stressors, TAVI may also have the potential to directly account for, accelerate or contribute to the evolution of these ischemic events on follow-up. Accordingly, the present review primarily focuses on potential association of TAVI with late coronary ischemic syndromes along with a particular emphasis on its mechanistic basis and clinical implications among TAVI recipients.
