Relationship Between Preoperative Anxiety and Atrial Fibrillation After Coronary Artery Bypass Graft Surgery.

Background: Atrial fibrillation is a form of arrhythmia that frequently occurs after coronary artery bypass graft surgery. Psychological factors may be involved in the development of atrial fibrillation, although the specific effect of anxiety remains unclear.

Purpose: This study was designed to evaluate the relationship between preoperative anxiety levels and atrial fibrillation after coronary artery bypass graft surgery.

Objective: To compare immediate postoperative results in patients receiving heparin-albumin-coated and non-coated circuits.

Methods: A total of 241 patients undergoing on-pump cardiac surgery were divided into two groups: those receiving heparin-coated circuits (Bioline®, Maquet Cardiopulmonary AG., Hirrlingen, Germany) and those receiving non-coated circuits (Maquet Cardiopulmonary AG.

Investigation of the Relationship between Cerebral Near-Infrared Spectroscopy Measurements and Cerebrovascular Event in Coronary Artery Bypass Grafting Operation in Patients without Carotid Stenosis and Patients with Carotid Stenosis below Surgical Margins.

Objectives: Stroke is an important cause of mortality and morbidity in surgery. In the present study, we examined the cerebral oximetry values of patients with carotid artery stenosis who did not present surgical indications and those who did not present carotid artery stenosis in coronary artery bypass grafting (CABG) surgery by comparing their cerebral oximetry values with cerebrovascular disease (CVD).

Methods: Between January and May 2014, 40 patients who underwent isolated CABG were included in the study.

Investigation of the Effect of Pulsatile and Nonpulsatile Flow on Kidney in Coronary Surgery With NIRS.

Background: Acute renal insufficiency is a significant cause of morbidity and mortality after coronary artery bypass grafting performed with cardiopulmonary bypass. Functional near-infrared spectroscopy (fNIRS) is an emerging brain-imaging technique that can be used to detect organ perfusions in adults. This study aims to determine the effects of pulsatile and nonpulsatile flow on renal circulation by using functional near-infrared spectroscopy and biochemical markers.

Assessment of healthy lifestyle behaviors after coronary artery bypass surgery.

Objective: After coronary artery bypass graft (CABG) surgery, there is a disease management process that patients should follow, and healthy behaviors play a key role in this process. The aim of this study was to evaluate the healthpromoting behaviors of patients after CABG surgery and to determine the influential factors.

Methods: This was a cross-sectional study of 152 patients who were admitted to the polyclinic between March and June 2016 and underwent a CABG procedure.

Sutureless versus Conventional Aortic Valve Replacement: Outcomes in 70 High-Risk Patients Undergoing Concomitant Cardiac Procedures.

In elderly, high-risk surgical patients, sutureless aortic valve replacement (AVR) can often be an alternative to conventional AVR; shorter aortic cross-clamp and cardiopulmonary bypass times are the chief advantages. We compared the outcomes of sutureless AVR with those of conventional AVR in 70 elderly patients who underwent concomitant cardiac surgical procedures. We retrospectively analyzed the cases of 42 men and 28 women (mean age, 70.

Immediate Outcomes of Aortic Valve Replacement with Sutureless versus Stentless Bioprosthesis.

Background: Aortic valve replacement (AVR) with a sutureless valve is an innovative therapy in high-risk elderly patients. The study aim was to compare the early results of AVR using sutureless aortic valves or stentless aortic bioprostheses.

Methods: A retrospective analysis was conducted of 55 patients who underwent AVR with either a sutureless valve (Perceval S; n = 24 or Edwards Intuity; n = 9) or a stentless valve (Sorin Freedom SOLO™; n = 22).

Early Outcomes of Sutureless Aortic Valves.

Background: In elderly high-risk surgical patients, sutureless aortic valve replacement (AVR) should be an alternative to standard AVR. The potential advantages of sutureless aortic prostheses include reducing cross-clamping and cardiopulmonary bypass (CPB) time and facilitating minimally invasive surgery and complex cardiac interventions, while maintaining satisfactory hemodynamic outcomes and low rates of paravalvular leakage. The current study reports our single-center experience regarding the early outcomes of sutureless aortic valve implantation.

Missed retrosternal ectopic thyroid tissue in a patient operated for multinodular goiter.

Ectopic thyroid tissue has been found from the tongue to the diaphragm. The most common ectopic thyroid tissue has been found in the tongue, submandibular region, cervical lymph nodes, larynx, trachea, oesophagus, mediastinum, diaphragm and heart respectively. "Forgotten goiter" is an extremely rare disease which is defined as a mediastinal thyroid mass found after total thyroidectomy.

Forearm compartment syndrome caused by reperfusion injury.

Compartment syndrome is commonly seen following lower extremity ischemia. However, upper extremities' compartment syndrome, especially after any vascular surgical procedures, is infrequent. Herein we report a case of an acute forearm compartment syndrome that was developed after delayed brachial artery embolectomy.

Successful use of fondaparinux in a patient with heparin-induced thrombocytopenia while on extracorporeal membrane oxygenation after mitral valve redo surgery.

In patients with respiratory failure and impairment of the left ventricle, arteriovenous extracorporeal membrane oxygenation (ECMO) offers further therapeutic options. Systemic anticoagulation is mandatory and heparin is routinely administrated. However, repeated exposure to heparin may cause heparin-induced thrombocytopenia (HIT) and carries a risk of thrombotic mortality and morbidity.

Surgical treatment of culture-negative aortic infective endocarditis.

Background: We retrospectively analyzed the results of operations done for culture-negative aortic infective endocarditis at a single center over a period of 26 years.

Methods: From June 1985 to January 2011, we operated on 82 patients with infective endocarditis of the aortic valve for which the results of culture were negative. Sixty-five of the patients (79.

Postoperative revision surgery for bleeding in a tertiary heart center.

We analyzed cases of re-exploration for bleeding after 19,680 open heart operations performed between January 1995 and January 2009 to determine the risk factors for mortality and morbidity. Half of the 282 patients reexplored had nonsurgical causes of bleeding. The patients were grouped according to the timing of reoperation, early re-exploration being on the day of the operation.

Biventricular repair of right atrial isomerism with complex congenital anomalies.

Biventricular repair is usually difficult to achieve in patients who have right atrial isomerism, which is typically associated with other complex cardiac anomalies. The procedure can be used in patients who have balanced ventricular structures. Herein, we report a successful surgical reconstruction, including biventricular repair, in a 4-year-old boy.

Surgical treatment of cardiac hydatid disease in 13 patients.

Cardiac hydatidosis is an uncommon but potentially fatal disease. It remains endemic in developed and developing countries. Its clinical presentation ranges from an absence of symptoms to congestive heart failure or other life-threatening sequelae.

Increasing numbers of penetrating cardiac trauma in a new center.

Background: Our aim was to express the importance of emergency diagnosis and surgical approach in penetrating cardiac trauma patients.

Methods: Koşuyolu Heart and Research Hospital moved to its new location in Cevizli Kartal in June 2005. Due to its close proximity to the main roads of the city, the number of trauma cases has increased tremendously.

Repair of left ventricular pseudoaneurysms.

The outcomes of 3 different methods of repair of left ventricular pseudoaneurysm after myocardial infarction were analyzed retrospectively. The operations were carried out in 22 patients between 1985 and 2008. Repair procedures included primary closure with Teflon-pledgeted sutures, and Dacron or pericardial patches.

Effects of patient-prosthesis mismatch on postoperative early mortality in isolated aortic stenosis.

Background And Aim Of The Study: Small valve size and patient-prosthesis mismatch (PPM) generate high postoperative transvalvular gradients and may decrease both early and long-term survival.
