Background: The aim of the study was to assess the feasibility and effectiveness of the irrigated radiofrequency modified maze procedure through a port-access approach during mitral valve surgery. Methods: Forty-three patients with atrial fibrillation (AF) and mitral valve disease underwent a combined procedure through a port-access approach. The indication was a history of continuous AF for more than 6 months in patients eligible for minimally invasive mitral valve surgery. Results: The incidence ...

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. Yaş ortalaması 65 ...

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 ...

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 ...

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 ...

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 ...

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

Background: This study was conducted to evaluate the effectiveness of the saline-irrigated radiofrequency modified maze operation for the treatment of chronic atrial fibrillation (AF) and compare the results of the left and bi-atrial procedures. Material and method: During a period of two years 105 patients with chronic AF having concomitant cardiac surgery underwent the procedure. Patients underwent either a bi-atrial (n = 48) or left atrial (n = 57) maze procedure. The first twenty patients ...
