Publication Metadata only Predictors of health related quality of life in patients wi̇th pulmonary hypertension(2022-02-07) KOCAKAYA, DERYA; ATAŞ, HALİL; YILDIZELİ, BEDRETTİN; MUTLU, BÜLENT; KOCAKAYA D., ŞİŞMAN A., AKASLAN D., ATAŞ H., YILDIZELİ B., MUTLU B.Publication Metadata only Prevalence of Coronary Artery to Pulmonary Artery Collaterals in Patients with Chronic Thromboembolic Pulmonary Hypertension: Retrospective Analysis from a Single Center(GEORG THIEME VERLAG KG, 2018) KEPEZ, ALPER; Kepez, Alper; Mutlu, Bulent; Paudel, Ashok; Ileri, Cigdem; Atas, Halil; Yildizeli, BedrettinBackground Our aim was to determine the prevalence of coronary artery-pulmonary artery collaterals in patients with chronic thromboembolic pulmonary hypertension (CTEPH) by retrospectively evaluating coronary angiograms of eligible consecutive patients who had undergone pulmonary endarterectomy (PEA). We also aimed to evaluate predictors and potential clinical associates of these collaterals. Methods Coronary angiograms of 83 consecutive CTEPH patients who had undergone coronary angiography before PEA operation between January 1, 2012 and June 1, 2015 were retrospectively evaluated for presence of coronary artery-pulmonary artery collaterals. Medical records of all patients were also retrospectively reviewed for demographic information, cardiovascular risk factors, preoperative right heart catheterization reports, operation reports, and follow-up data. Data of CTEPH patients with coronary artery-pulmonary artery collaterals were compared with data of CTEPH patients without such collaterals. Results There were 15 patients (18.1%) with definite and 4 patients (4.8%) with probable coronary artery-pulmonary artery collaterals among the study population. CTEPH patients with collaterals had higher preoperative pulmonary artery pressures, higher pulmonary vascular resistance (PVR) and lower cardiac index values compared with CTEPH patients without collaterals. However, CTEPH patients with collaterals displayed higher amount of reduction in PVR after PEA compared with patients without collaterals. There were no significant differences between groups regarding incidence of reperfusion injury or mortality. Conclusion Prevalence of coronary artery-pulmonary artery collaterals seems to be increased in our CTEPH patients compared with the general population. The presence of coronary artery-pulmonary artery collaterals is often combined with proximal disease with the possibility of increased reduction of PVR after PEA operation.Publication Metadata only The anatomical relationship between the axillary artery and vein investigated by radial coronary angiography(WILEY, 2018) KEPEZ, ALPER; Sert, Sena; Kepez, Alper; Atas, Halil; Mutlu, Bulent; Erdogan, OkanAimsTo reduce the risk of inadvertent arterial puncture and bleeding, we aimed to define a safe puncture site by demonstrating the relation of the axillary artery and vein. MethodsThe anatomical course and relation as well as crossover sites of the axillary artery and vein, the presence of small arterial bridges over the axillary vein, and validation of commonly preferred axillary venous puncture sites were determined by simultaneous ipsilateral venography in patients (n=111; 80 men, age 60 10 years) who underwent coronary angiography by radial artery access. ResultsThe axillary vein was detected at the first costa-clavicular intersection in 62% and at the second anterior and third posterior costal intersection in 60% of the patients. Small arterial bridges over the axillary vein were observed in 77% of the patients and more frequently in females and body mass index 25kg/m(2) (P=0.034 and P=0.03, respectively). The axillary artery crossed the vein in 24% of the patients and almost always within the region close to the first costa-clavicular intersection site. ConclusionOur study demonstrated a high crossover rate (24%) of axillary artery and vein and a high degree of variation in the course of axillary vein. Small arterial bridges over the axillary vein were observed in 77% of the patients.Publication Metadata only The effects of iron replacement on functional capacity in patients with group 1 and group 4 pulmonary hypertension(2022-10-01) ATAŞ, HALİL; KOCAKAYA, DERYA; YILDIZELİ, BEDRETTİN; MUTLU, BÜLENT; Akaslan D., Aslanger E., ATAŞ H., Kanar B. G. , KOCAKAYA D., YILDIZELİ B., MUTLU B.Objective: Abnormal iron handling complicates pulmonary hypertension and causes functional limitation and poor outcomes. Although preliminary results in group 1 pulmonary hypertension patients support the use of iron replacement, whether this applies to other PH subgroups is not known.
