  • increased prevalence of varicocele in patients with Coronary Artery ectasia
    Coronary Artery Disease, 2005
    Co-Authors: Ertan Yetkin, Suleyman Kilic, Nusret Acikgoz, Huseyin Ergin, Yuksel Aksoy, Isa Sincer, Erdal Akturk, Ali Beytur, Nasir Sivri, Hasan Turhan
    Abstract:

    Background Coronary Artery ectasia (CAE) is defined as localized or diffuse non-obstructive lesions of the epicardial Coronary arteries with a luminal dilation exceeding the 1.5-fold of normal adjacent segment or vessel diameter. Varicocele is the dilatation of the pampiniform plexus. Recently increased prevalence of peripheral varicose veins has been shown in patients with CAE. In this study we aimed to assess the prevalence of varicocele, which is dilatation of another venous system, in patients with CAE. Materials and methods Thirty-five male consecutive patients with Coronary Artery ectasia in combination with or without Coronary Artery disease (CAD) and 63 male, age-matched patients with Coronary Artery disease were included in the study. All patients were evaluated for the presence of varicocele. Results Twenty-one patients with CAE were found to have varicocele (62% of group I patients). In patients with CAD, 24 patients (38%) were found to have varicocele. The difference between the two groups in respect to presence of varicocele was statistically significant (P=0.02; odds ratio=1.57; 95% confidence interval 1.05– 2.3). Conclusion We have shown that patients with Coronary Artery ectasia have an increased prevalence of varicocele compared to those with Coronary Artery disease. The mechanism underlying Coronary Artery ectasia might further increase the prevalence of varicocele in susceptible patients.

  • comparison of c reactive protein levels in patients with Coronary Artery ectasia versus patients with obstructive Coronary Artery disease
    American Journal of Cardiology, 2004
    Co-Authors: Hasan Turhan, Ali Riza Erbay, Ayse Saatci Yasar, Mustafa Mucahit Balci, Asuman Bicer, Ertan Yetkin
    Abstract:

    This study evaluated plasma C-reactive protein (CRP) levels, a specific marker of inflammation, in 32 patients with isolated Coronary Artery ectasia (CAE) and compared the results with those of 32 patients with obstructive Coronary Artery disease without Coronary Artery ectasia and 30 subjects with angiographically normal Coronary arteries. CRP levels were found to be significantly higher in patients with isolated CAE (p <0.001), suggesting that more severe inflammation may be involved in the pathogenesis of CAE.

  • double left anterior descending Coronary Artery arising from the left and right Coronary arteries a rare congenital Coronary Artery anomaly
    Heart and Vessels, 2004
    Co-Authors: Hasan Turhan, Ramazan Atak, Ali Riza Erbay, Kubilay Senen, Ertan Yetkin
    Abstract:

    Double left anterior descending Coronary Artery arising from the left and right Coronary arteries is a very rare congenital Coronary Artery anomaly. In this report, we describe a patient with double left anterior descending Coronary Artery originating from the left and right Coronary arteries. To the best of our knowledge, dual connection of the left anterior descending Coronary Artery to the left and right Coronary arteries has been described in only five patients.

  • minimally invasive Coronary Artery bypass grafting
    The Annals of Thoracic Surgery, 1996
    Co-Authors: Michael J Mack, Tea E Acuff, Rodney J Landreneau, Bartley P Griffith
    Abstract:

    Background. Standard options for the invasive management of proximal disease of the left anterior descending Coronary Artery include Coronary Artery bypass grafting with a left internal mammary Artery and percutaneous transluminal Coronary angioplasty. Methods. We describe a surgical technique for bypass of the left anterior descending Coronary Artery with a left internal mammary Artery without median sternotomy and without cardiopulmonary bypass. Thoracoscopy is used to harvest the internal mammary Artery, whereas the mammary-Coronary Artery anastomosis is performed under direct vision through a limited anterior thoracotomy. Results. We have performed this procedure successfully in 3 patients with minimal morbidity and shortened hospital stay. Average operative time was 3 hours and postoperative hospital stay averaged less than 48 hours. Conclusions. Although experience is limited and follow-up is very short, with further experience, this less invasive surgical technique may become a viable option for the management of proximal left anterior descending disease.

  • relation between functional Coronary Artery stenosis and graft occlusion after Coronary Artery bypass grafting
    The Journal of Thoracic and Cardiovascular Surgery, 2021
    Co-Authors: Ho Young Hwang, Myoung Jin Jang, Jin Chul Paeng, Jeehoon Kang, Kibong Kim
    Abstract:

    Abstract Objectives This study was conducted to evaluate graft patency rates during the 5 years after Coronary Artery bypass grafting according to the functional significance of the Coronary Artery stenosis, as determined by myocardial single-photon-emission computed tomography. Methods Two hundred ninety-five patients who underwent Coronary Artery bypass grafting using Y-composite grafts based on the in situ left internal thoracic Artery, and in whom preoperative stress/rest myocardial single-photon-emission computed tomography and 1-year angiographies were available were enrolled. Seven hundred sixty-nine and 262 distal anastomoses were constructed to ischemic and nonischemic areas, respectively. One-year and 5-year angiographic occlusion rates were evaluated in all and 80.3% of study patients, respectively. Factors associated with graft occlusion were evaluated using generalized linear mixed-effects models. Results Overall 1- and 5-year graft occlusion rates were 4.3% (44 of 1031 distal anastomoses) and 5.5% (45 out of 820), respectively. The occlusion rates of grafts bypassed to vessels with functionally significant and insignificant stenosis were 2.7% (21 out of 769) and 8.8% (23 out of 262) at 1 year and were 4.0% (25 out of 618) and 9.9% (20 out of 202) at 5 years, respectively. Graft occlusion during the 5 years after Coronary Artery bypass grafting was associated with the functional significance of Coronary Artery stenosis (odds ratio, 0.50; 95% confidence interval, 0.28-0.92). The odds ratio of the graft occlusion according to functional ischemia was lower and significant in grafts to arteries with intermediate stenosis (stenosis ≥70% but Conclusions Graft occlusion during the 5 years after Coronary Artery bypass grafting was associated with the functional significance of Coronary Artery stenosis, particularly when the stenosis degree was not severe.

CONCLUSIONS Graft occlusion during the 5 years after Coronary Artery bypass grafting was associated with the functional significance of Coronary Artery stenosis, particularly when the stenosis degree was not severe.
