Aortanın ileri derecede aterosklerozunda koroner arter cerrahisi
Authors:
Publisher and Date:(1999)Açık kalp cerrahisinde tekniklerin ilerlemesine rağmen nörolojik komplikasyonların görülme sıklığı azalmamıştır ve inme (stroke) morbidite ve mortaliteyi önemli ölçüde artırmaktadır. Bu yazıda çıkan aortada ileri derecede kalsifikasyon bulunan vakalarda hipotermik fibrilasyon tekniği kullanılarak aortaya dokunulmadan ve kross klemp konulmadan yapılan koroner by-pass ameliyatları anlatıldı. 2 yıl içinde aortada ileri derecede kalsifikasyon bulunan 23 olguda bu teknik kullanıldı.

Atriyal fibrilasyonun cerrahi tedavisi
Authors:
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 ...

Combined radiofrequency ablation and myxoma resection through a port access approach
Authors:
Publisher and Date:(Elsevier Science Inc, 2004)Myxornas are common cardiac tumors that are traditionally managed by complete excision through a median sternotorny approach with the use of cardiopulmonary bypass. We discuss a patient with left atrial myxoma and chronic atrial fibrillation who underwent surgical excision and combined irrigated radiofrequency ablation for atrial fibrillation through a Port Access approach. Minimally invasive operations constitute an expanding field for the treatment of many cardiac diseases and may be an alternative ...

Combined radiofrequency modified maze and mitral valve procedure through a port access approach: early and mid-term results
Authors:
Publisher and Date:(Oxford University Press, 2003)Objective: The aim of this study was to assess the feasibility and effectiveness of irrigated radiofrequency (RF) modified Maze procedure through a port access approach during mitral valve surgery and evaluate early and mid-term results. Material and method: During a 16 months time period 67 patients with chronic atrial fibrillation (AF) eligible for port access mitral valve surgery were randomly assigned to either Group A in which they underwent a combined procedure (N = 33) or Group B in which ...

Does different orientation of the Medtronic Hall tilting disc valve in the aortic position effect transvalvuler pressure gradients?
Authors:
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 ...

Does off-pump CAPG reduce gastrointestinal complications?
Authors:
Publisher and Date:(Elsevier Science Inc, 2004)Background. The aim of this study was to compare gastrointestinal complications and associated risk factors among patients undergoing cardiac surgery using off- and on-pump revascularization techniques. Methods. A total of 1146 adult patients who underwent coronary artery surgery during a 6-year period were evaluated retrospectively. Group 1 consisted of 546 patients operated using off-pump techniques and group 2 consisted of 600 cases operated with cardiopulmonary bypass. Patients were compared ...

Does off-pump coronary artery bypass surgery reduce mortality in high risk patients?
Authors:
Publisher and Date:(Forum Multimedia Publishing LLC., 2001)Background: The aim of this retrospective study was to compare outcome in two groups of patients who were classified according to their risk groups and underwent coronary revascularization with or without cardiopulmonary bypass. Material and Methods: Between January 1996 and July 2000 480 cases that underwent coronary artery bypass surgery (CABG) were included in a retrospective nonrandomized manner for study. Group I included 210 patients who were revascularized using off-pump techniques. Octopus ...

Genetic variations of the apolipoprotein B gene in Turkish patients with coronary artery disease
Authors:
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 ...

Hemodilution during off-pump coronary artery bypass grafting: Can we improve flow and reduce hypercoagulability?
Authors:
Publisher and Date:(Forum Multimedia Publishing LLC., 2003)Background: The aim of this study was to compare intraoperative coronary graft flows performed on pump and off pump and to evaluate the effects of hemodilution on coronary graft flows in off-pump coronary artery bypass grafting (CABG) patients by using transit time flow measurements (TTFM). Methods: Three hundred patients undergoing only CABG procedures were enrolled in a prospective randomized manner into 3 groups. Group 1 consisted of 100 patients undergoing operations with standard cardiopulmonary ...

Intraoperative saline-irrigated radiofrequency modified maze procedure for atrial fibrillation
Authors:
Publisher and Date:(Elsevier Science Inc, 2002)Background. This study was conducted to evaluate the effectiveness of the saline-irrigated radiofrequency modified Maze operation for treatment of chronic atrial fibrillation and to compare the results of the left and biatrial procedures. Methods. During a period of 11 months 62 patients with chronic atrial fibrillation who were having concomitant cardiac surgery underwent the procedure. The mean age of the patients was 52 +/- 14 years. Patients underwent either a biatrial (group A

Koroner cerrahisinde tek klemp tekniğinin nörolojik ve kardiyak sonuçlar üzerine etkisi
Authors:
Publisher and Date:(2001)Amaç: Koroner bypass cerrahisi sırasında tek ve çift klemp tekniklerinin kardiyak ve nörolojik sonuçları retrospektif olarak araştırıldı. Materyal ve Metod: 680 olguda (Grup 1) distal ve proksimal anastomozlar aortada kros klemp kaldırılmadan (tek klemp) tamamlandı. 820 olguda ise konvansiyonel yan klemp tekniği (çift klemp) kullanıldı ve distal anastomozlar tamamlandıktan sonra kros klemp kaldırılarak proksimal anastomozlar için yan klemp yerleştirildi (Grup 2). Acil girişimler çalışma dışı ...

Off-pump coronary artery bypass grafting with use of the octopus 2 stabilization system
Authors:
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 ...

The surgical treatment of atrial fibrillation
Authors:
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 ...
