    Akut İnferior Miyokard İnfarktüsü ile Gelen Hastada Sağ Sinus Valsalvadan Köken Alan Dominant Sirkumfleks Arter Oklüzyonu ve Sağ Radial Arter Yoluyla Yapılan Başarılı Primer Perkütan Koroner Girişim
    (Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2013-04-04) DEğirmencioğlu, Aleks; Akyol, Ahmet
    ÖZET Primer perkütan koroner girişim ST elevasyonlu miyokard infarktüsünde ilk tercih edilen tedavi yöntemi olup son yıllarda bu işlemin radial arter yoluy la yapılması popülarite kazanmıştır. Bununla birlikte, özellikle anatomik anormallikler varlığında radial yaklaşım bazen zor olabilmektedir. Bu ya zıda akut miyokard infarktüsü ile başvuran ve koroner anomalisi olmasına rağmen radial yoldan başarılı primer perkütan koroner girişim yapılan bir hasta sunulmuştur.

    An analysis of the learning curve for robotic-assisted mitral valve repair
    (WILEY, 2021-01-01) Gullu, Ahmet U.; Senay, Sahin; Kocyigit, Muharrem; Zencirci, Ertugrul; Akyol, Ahmet; Degirmencioglu, Aleks; Karakus, Gultekin; Ersin, Egemen; Karabiber, Alara; Alhan, Cem
    Background Many cardiac surgeons receive training for sternotomy-based cardiac surgical operations in residency programs and only a few education programs offer training specifically in minimally invasive cardiac surgery. In this report, we aimed to search and analyze the learning curve for robotic-assisted mitral valve (MV) repair in cardiac surgeons. Method Between January 2010 and July 2019, 60 robotic-assisted isolated MV repair surgeries were performed with DaVinci Robotic Systems in our center. Different kinds of surgical techniques were used. The assessment of the learning curve was based on cardiopulmonary bypass (CPB) and transthoracic aortic clamp (CC) times. Result There were 23 (38.3\%) men and 37 (61.7\%) women with a mean age of 48.3 years. The lesions of the MV were posterior leaflet prolapsus (n = 42, 70.0\%), anterior leaflet prolapsus (n = 8, 13.3\%), Barlow disease (n = 3, 5\%), and annular dilatation (n = 7, 11.6\%). The patients underwent notochordal implantation (n = 27, 45\%), quadrangular or triangular resection (n = 23, 38.3\%), isolated ring annuloplasty (n = 7, 11.7\%), resection, and leaflet reduction (n = 2, 3.3\%) or edge to edge repair (n = 1, 1.7\%). The maturation of the learning curve appeared to be about 30 cases. The statistical analysis showed that the mean CPB and CC times for the first 30 cases were greater compared with the 30 after learning curve (155.3 vs. 118.9 min {[}p = .00], 102.3 vs. 80 min {[}p = .00], respectively). There was no case of conversion to open surgery. No perioperative mortality was observed. Conclusion The maturation of the learning curve for robotic-assisted MV repair appeared to be about 30 cases in our group of patients. This study had encouraging results for surgeons who desire to start a robotic mitral surgery program.

    Contrast Induced Nephropathy can be Surpassed with Meticulous Attention Even in Patients with Severe Renal Dysfunction
    (Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2013-07) Değirmencioğlu, Aleks; Karakuş, Gültekin; Zencirci, Ertuğrul; Akyol, Ahmet
    ABSTRACT Contrast induced nephropathy (CIN) is one of the most important complications of the percutaneous coronary intervention (PCI) and may lead to dialysis especially in the presence of baseline high creatinine level. Here we describe coronary angiography and subsequent successful PCI of proximal left anterior descending (LAD) artery lesion without developing CIN in patient who has medically refractory angina pectoris and baseline very high creatinine level (6.3 mg/dl). This case report illustrates the potential role of invasive approach in patients with coronary artery disease even in the presence of severe renal dysfunction by using preventive measures and close monitoring.

    Current clinical practice of cardiac resynchronization therapy in Turkey: Reflections from Cardiac Resynchronization Therapy Survey-II
    (TURKISH SOC CARDIOLOGY, 2020-01-01) Kocyigit, Duygu; Sarigul, Nedim Umutay; Altin, Ali Timucin; Cay, Serkan; Polat, Veli; Saygi, Serkan; Gumrukcuoglu, Hasan Ali; Gemici, Kani; Ikitimur, Baris; Akyol, Ahmet; Bilge, Ahmet Kaya; Basarici, Ibrahim; Ozcan, Emin Evren; Demir, Mesut; Kabul, Hasan Kutsi; Ornek, Ender; Normand, Camilla; Linde, Cecilia; Dickstein, Kenneth
    Objective: Cardiac resynchronization therapy (CRT) has been shown to reduce mortality in selected patients with heart failure with reduced ejection fraction (HFrEF). CRT Survey-II was a snapshot survey to assess current clinical practice with regard to CRT. Herein, we aimed to compare Turkish data with other countries of European Society of Cardiology (ESC). Methods: The survey was conducted between October 2015 and December 2016 in 42 ESC member countries. All consecutive patients who underwent a de novo CRT implantation or a CRT upgrade were eligible. Results: A total of 288 centers included 11,088 patients. From Turkey, 16 centers recruited 424 patients representing 12.9\% of all implantations. Compared to the entire cohort, Turkish patients were younger with a lower proportion of men and a higher proportion with ischemic etiology. Electrocardiography (ECG) showed sinus rhythm in 81.5\%, a ORS duration of <130 ms in 10.1\%, and >= 150 ms in 63.8\% of patients. Left bundle branch block (LBBB) was more common. Median left ventricular ejection fraction (LVEF) was 25\%, lower than in the overall ESC cohort, but NYHA class was more often II. Most common indication for CRT implantation was HF with a wide ORS (70.8\%). Almost 98.3\% of devices implanted were CRT-D, in contrast to the overall cohort. Fluoroscopy time was longer, but duration of overall procedure was shorter. LV lead implantation was unsuccessful in 2.6\% patients. Periprocedural complication rate was 6.3\%. The most common complication was bleeding. Remote monitoring was less utilized. Conclusion: These are the first observational data reflecting the current CRT practice in Turkey and comparing it with other countries of Europe. Findings of this study may help detect gaps and provide insights for improvement.
