Publisher and Date:(Türk Kardiyoloji Derneği / Kare Yayıncılık, 2007)Teknolojideki hızlı gelişmeler atriyal fibrilasyonun (AF) cerrahi tedavisinde birçok yenili¤i beraberinde getirmiştir. Maze III operasyonu, AF’nin cerrahi tedavisinde altın standart olarak kabul edilmekle beraber teknik zorluk ve baz› komplikasyonlar nedeniyle yayg›n kullanım alanı bulamamıştır. Alternatif enerji kaynaklarının kullanıma girmesi ile orijinal yöntem ile kesip dikerek oluşturulan lezyonlar bu enerji kaynaklarıyla çok daha kısa sürede emniyetle oluşturulmaktadır. Bu işlemlerle %70-98 ...

Authors:Güden, Metin; Akpınar, Belhhan; Sağbaş, Ertan; Sanisoğlu, İlhan; Arpaz, M.; Bayındır, Osman
Publisher and Date:(Medimond Srl, 2000)The effect of valve orientation during aortic valve replacement (AVR) with the Medtronic Hall (MH) tilting disc valve on transvalvuler pressure gradients was evaluated. 30 patients (pts) undergoing isolated AVR received a MH which was oriented so that the greater opening of the valve faced the non coronary aortic sinus. There were 12 male and 8 female pts in this group with a mean age of 59 +/- 5.2 years. An echocardiographic examination was performed 6 days after the operation and resting ...

Authors:Duman, Belgin Süsleyici; Türkoǧlu, Çavlan; Akpınar, Belhhan; Güden, Mustafa; Vertii, Anastassia; Çaǧatay, Penbe; Günay, Demet; Büyükdevrim, Ahmet Sevim
Publisher and Date:(Taylor & Francis Ltd, 2005)Background: The results of studies that clarify the association of genetic markers at the apolipoprotein B (apo B) gene (EcoRI and XbaI polymorphisms) with coronary artery disease (CAD) are not consistent and suggest that the effect is context dependent (dependent on ethnicity and sex). The present study represents the first investigation of the apo B gene polymorphisms in Turkish patients with CAD and their influence on lipid levels. Aim: The study investigated the association of apo B gene EcoRI ...

Off-pump coronary artery bypass grafting with use of the octopus 2 stabilization system
Authors:Akpınar, Belhhan; Güden, Mustafa; Sağbaş, Ertan; Sanisoğlu, İlhan; Aytekin, Vedat; Bayındır, Osman
Publisher and Date:(2000)Background: The treatment of coronary artery disease has evolved rapidly over the last two decades. The gold standard of surgical revascularization, the on-pump coronary artery bypass graft, has been challenged by the development of percutaneous transluminal coronary angioplasty. Our experience with the alternative of the off-pump ("beating heart") coronary artery bypass (OPCAB) technique during a period of 18 months suggests that OPCAB avoids the complications of cardiopulmonary bypass and offers ...

Authors:Akpınar, Belhhan; Sağbaş, Ertan; Güden, Mustafa; Sanisoğlu, İlhan
Publisher and Date:(Turkish Soc Cardiology, 2007)The surgical treatment of atrial fibrillation (AF) has entered a new era with the development of new tools and advanced techniques. The Maze III operation remains as the gold standard for the surgical treatment of AF. However new energy sources have been adopted for treating this arrhythmia in an effort to reduce the invasiveness and technical concerns with the original procedure. Success rates ranging between 70-98% have been reported using these new techniques. On the other hand interventional ...
