Öğe Aortic Valve Regurgitation and Ventricular Septal Defect Diagnosed 5 Years after Penetrating Cardiac Injury(Georg Thieme Verlag Kg, 2014) Ozdemir, Ahmet Coskun; Yuksel, Volkan; Huseyin, Serhat; Baltalarli, AhmetDespite high mortality rates for penetrating heart injuries, developments in transport, diagnosis, and surgical interventions have increased survival rates. In some cases, life-threatening complications may be misdiagnosed or remain asymptomatic and lead to loss of life. Herein, we report a patient with aortic valve regurgitation because of noncoronary cusp perforation and ventricular septal defect that remained asymptomatic and diagnosed 5 years after a penetrating heart injury.Öğe Impact of Surgeon Experience During Carotid Endarterectomy Operation and Effects on Perioperative Outcomes(Soc Brasil Cirurgia Cardiovasc, 2016) Yuksel, Volkan; Ozdemir, Ahmet Coskun; Huseyin, Serhat; Guclu, Orkut; Turan, Fatma Nesrin; Canbaz, SuatObjective: We evaluated the effect of surgeon experience on complication and mortality rates of carotid endarterectomy operation. Methods: Fifty-nine consecutive patients who underwent carotid endarterectomy between January 2013 and February 2016 were divided into two groups. Patients who had been operated by surgeons performing carotid endarterectomy for more than 10 years were allocated to group 1 (experienced surgeons; n=34). Group 2 (younger surgeons; n=25) consisted of patients operated by surgeons independently performing carotid endarterectomy for less than 2 years. Both groups were compared in respect of operative results and postoperative complications. Results: No intergroup difference was found for laterality of the lesion or concomitant coronary artery disease. In group 1, signs of local nerve damage (n=2; 5.9%) were detected, whereas in group 2 no evidence of local nerve damage was observed. Surgeons in group 1 used local and general anesthesia in 3 (8.8%) and 31 (91.2%) patients, respectively, while surgeons in group 2 preferred to use local and general anesthesia in 1 (4%) and 24 (96%) patients, respectively. Postoperative stroke was observed in group 1 (n=2; 5.9%) and group 2 (n=2; 5.8%). Conclusion: Younger surgeons perform carotid endarterectomy with similar techniques and have similar results compared to experienced surgeons. Younger surgeons rarely prefer using shunt during carotid endarterectomy. The experience and the skills gained by these surgeons during their training, under the supervision of experienced surgeons, will enable them to perform successful carotid endarterectomy operations independently after completion of their training period.Öğe Simple left atrial reduction in giant left atrium accompanying mitral stenosis(Termedia Publishing House Ltd, 2012) Ozdemir, Ahmet Coskun; Emrecan, BilginA patient with giant left atrium due to rheumatic mitral valve disease with spontaneous echocardiographic contrast in the giant left atrium is presented in this case report. The left atrial diameter reduction from dimensions of 118 x 104 mm to 80 x 77 mm was attained by excision of two-centimeter wide strips of left atrium on both sides by widely plicating the left atrial appendage from the inside with running polypropylene sutures. Spontaneous echocardiographic contrast disappeared in the postoperative echocardiographic control. The patient had uneventful recovery in the postoperative period and was discharged on the fifth day after the operation.Öğe Surgical pitfalls of minimally invasive direct coronary artery bypass procedure from the viewpoint of a surgeon in the learning curve(Termedia Publishing House Ltd, 2013) Emrecan, Bilgin; Ozdemir, Ahmet CoskunIntroduction: Minimally invasive direct coronary artery bypass grafting (MIDCAB) offers arterial revascularization of the left anterior descending (LAD) coronary artery especially in lesions unsuitable for percutaneous coronary interventions. By avoidance of sternotomy and cardiopulmonary bypass its invasiveness is less than that of conventional bypass surgery. Aim: We in this study discuss our surgical experience in the MIDCAB procedure. Material and methods: Thirteen patients were operated on with the MIDCAB procedure. The inclusion criteria for MIDCAB were pure LAD disease totally occluded or severely stenotic. Patient demographics and preoperative and postoperative data were analyzed. Results: Mean age of the patients was 60.0 +/- 8.6 years. Patients' preoperative and postoperative levels of cardiac CK-MB (creatine kinase MB) were not significantly different (p = 0.993). However, cardiac troponin I (p < 0.001), hemoglobin (p < 0.001) and hematocrit (p < 0.001) were significantly different. No perioperative myocardial infarctions or cerebrovascular accidents were seen. The patients were discharged at a mean day of 4.77 with oral antiaggregant therapy. No mortality was seen in the study population. Conclusions: Minimally invasive direct coronary artery bypass is associated with few perioperative complications. Minimally invasive direct coronary artery bypass in our experience is a very good option for single vessel LAD disease.Öğe Vascular Complications of the Intra-aortic Balloon Pump in Patients Undergoing Open Heart Surgery: 10 Years' Experience(Georg Thieme Verlag Kg, 2013) Yuksel, Volkan; Huseyin, Serhat; Ozdemir, Ahmet Coskun; Ege, TuranBackground The most encountered complications with intra-aortic balloon pump (IABP) use are seen within the vascular system. The purpose of our study is to evaluate vascular complications of the sheathless IABP in patients undergoing open heart surgery. Methods Between January 2002 and December 2011, a total of 148 patients undergoing open heart surgery and needed IABP support were included in the study. All vascular complications related with IABP were recorded. Results Mean age of the patients was 64.4 +/- 9.4 years. Total 104 (70.2%) were male and 44 (29.8%) were female. Total number of patients who had ischemic complications of the extremity was 13 (8.7%). The most used surgical treatment was embolectomy in five patients. Only one patient required an iliofemoral bypass. Above the knee amputation was performed in one patient. No balloon-related mortality occurred. Conclusion Incidence of vascular complications in IABP counterpulsation is still a problem despite improvements in catheter design and techniques. The presence of peripheral arterial disease and diabetes mellitus is important risk factors for ischemic complications.
