Physicochemical and photocatalytic properties of AgCrO/FeO/CeO ternary nanocomposite.

The study presents AgCrO/FeO/CeO ternary nanocomposite, based on FeO/CeO binary composites, which demonstrated excellent photocatalytic performance in the photodegradation of methylene blue under solar irradiation. The AgCrO/FeO/CeO nanocomposites was orthorhombic, ilmenite, and cubic-fluorite phases of AgCrO, FeO, and CeO, respectively, according to the XRD examination. A strong bond between AgCrO, FeO, and CeO within the nanocomposite was demonstrated by the SEM and TEM investigations.

Long Term Survival Benefits of Different Conduits Used in Coronary Artery Bypass Graft Surgery- A Single Institutional Practice Over 20 Years.

Objective: This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort.

Methods: A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery). The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery.

The Convergent Ablation and AtriClip Exclusion of the Left Atrial Appendage in Long-Standing Persistent Atrial Fibrillation.

We here present a case of a 54-year-old man with longstanding persistent atrial fibrillation refractory to direct current electrical cardioversion who underwent a concurrent convergent ablation and Atriclip exclusion of left atrial appendage. His preoperative echocardiography revealed dilated 5.8 cm left atrium with a normal left ventricular ejection fraction of 50%.

Chylopericardium associated with constrictive pericarditis assessed by multimodality imaging.

Acute-onset presentation with breathlessness and calcific pericardial thickening encapsulating the heart. Extremely chylous pericardium, which is by itself rare, in combination with constriction assessed with multiple imaging modalities.

Long-term outcomes for different surgical strategies to treat left ventricular outflow tract obstruction in hypertrophic cardiomyopathy.

Aims: Surgical intervention is used to treat dynamic left ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy. This study assesses the effect of different surgical strategies on long-term mortality and morbidity.

Methods And Results: In total, 347 patients underwent surgical intervention for LVOTO (1988-2015).

Perioperative kinetics of endocan in patients undergoing cardiac surgery with and without cardiopulmonary bypass.

Introduction: Endothelial Specific Molecule-1 or endocan is a novel biomarker associated with the development of acute lung injury (ALI) in response to a systemic inflammatory state such as trauma. Acute Respiratory Distress syndrome (ARDS), a severe form of ALI is a devastating complication that can occur following cardiac surgery due to risk factors such as the use of cardiopulmonary bypass (CPB) during surgery. In this study we examine the kinetics of endocan in the perioperative period in cardiac surgical patients.

Ruptured saphenous vein graft aneurysm.

Ruptured saphenous vein graft (SVG) aneurysm is a rare source of significant morbidity and mortality. SVG is a common technique of coronary artery bypass grafting (CABG), but vein graft aneurysm and ruptured SVG aneurysm have not received the required attention as only few case reports exist. We present the case of a 50-year old man with ruptured vein graft aneurysm who had significant postoperative complications following surgery, and outline some preventive/management strategies.

Omental herniation: a rare complication of vacuum-assisted closure of infected sternotomy wound.

Vacuum-assisted closure (VAC) has recently been adopted as an acceptable modality for management of sternotomy wound infections. Although generally efficacious, the use of negative pressure devices has been associated with complications such as bleeding, retention of sponge, and empyema. We report the first case of greater omental hernia as a rare complication of vacuum-assisted closure of sternal wound infection following coronary artery bypass grafting.

Leiomyosarcoma of pulmonary vein presenting as left atrial mass: an outline of management principles.

Leiomyosarcoma of the pulmonary vein is rare and has poor prognosis. Its clinical features are nonspecific and mimic benign conditions. Early diagnosis is challenging.

Practice considerations of early aspirin administration following coronary artery bypass surgery.

Thrombotic occlusion of saphenous vein grafts (SVG), the conduits most commonly used in coronary artery bypass grafting (CABG) surgery, causes significant morbidity and mortality. There is class 1A evidence that early aspirin administration following CABG reduces thrombotic SVG occlusion, as well as overall morbidity and mortality. The American Heart Association/American College of Cardiology and the European Association of Cardiothoracic Surgeons have issued guidelines recommending that 150 to 325 mg aspirin be administered within 6 hours following CABG.

Transaortic mitral valve repair in double valve infective endocarditis.

We present a case of a transaortic mitral valve repair in double valve infective endocarditis. Through a conventional oblique aortotomy, the aneurysmal part of the anterior leaflet of the mitral valve was excised, an artificial neo chorda was implanted, and the aortic valve was replaced. 

Effect of valve suture technique on incidence of paraprosthetic regurgitation and 10-year survival.

Background: The primary objective was to estimate the risk of paraprosthetic regurgitation (PPR) after aortic (AVR) and mitral valve replacement (MVR) using interrupted (IN) or semicontinuous (SC) sutures. The secondary objective was to estimate the risk of redo valve surgery and 10-year survival after valve replacement performed using either suture technique.

Methods: Patients who underwent mechanical AVR or MVR using a St.

Kawasaki disease presenting as cardiac tamponade with ruptured giant aneurysm of the right coronary artery.

We report a case of a 22-year-old man with Kawasaki disease presenting with features of cardiac tamponade following rupture of giant aneurysm of his right coronary artery. He underwent an emergency operation. Aneurysmal sac was of size 4x4 cm.

A case series of myectomy: a review of its current application as an adjunct procedure.

In this article, we review the role played by myectomy in cardiac surgery. For this purpose, we looked at three cases of different etiology where myectomy in conjunction with treatment of the primary condition proved invaluable in the outcome of these patients. The primary conditions requiring treatment were subaortic membrane, hypertrophic obstructive cardiomyopathy with mitral valve regurgitation, and aortic stenosis.

Complex off-pump coronary artery bypass surgery can be safely taught to cardiothoracic trainees.

Objectives: Off-pump coronary revascularisation is demanding technically as the surgeon is faced with a beating heart and not a bloodless field. The potential clinical advantages of off-pump coronary revascularisation have made this procedure an essential part of a cardiothoracic training program. The aim of this study is to investigate the impact of teaching trainees complex off-pump coronary artery surgery (arterial grafting, 'Y' grafts, sequential grafting and minimally invasive direct coronary artery bypass) on clinical outcomes.

Effects of cell saver autologous blood transfusion on blood loss and homologous blood transfusion requirements in patients undergoing cardiac surgery on- versus off-cardiopulmonary bypass: a randomised trial.

Objective: Off-pump CABG is potentially associated with reduced intraoperative blood loss and homologous blood transfusion in comparison to on-pump CABG. In this randomised controlled study we investigated the effects of autologous cell saver blood transfusion on blood loss and homologous blood transfusion requirements in patients undergoing CABG on- versus off-CPB.

Methods: Eighty patients were randomised into one of four groups: (A) on-CPB with cell saver blood transfusion (CSBT), (B) on-CPB without CSBT, (C) off-pump with CSBT and (D) off-pump without CSBT.

Effects on lung function in patients undergoing coronary artery surgery on versus off cardiopulmonary bypass: a randomized trial.

Background: : Coronary revascularization is associated with respiratory dysfunction and poor gas exchange postoperatively. Cardiopulmonary bypass (CPB) has been implicated as a possible explanation for this phenomenon. This study investigated respiratory function in patients undergoing coronary artery bypass grafting (CABG) on-CPB versus off-CPB to determine whether the off-CPB condition results in improved postoperative pulmonary function.

Renal function after cardiac surgery off- versus on-pump coronary artery bypass: analysis using the Cockroft-Gault formula for estimating creatinine clearance.

Background: Cardiopulmonary bypass (CPB) is often associated with renal dysfunction, as measured by plasma creatinine levels and hemodialysis rates. This study compared creatinine clearance (CrCl), estimated with the Cockroft and Gault formula, between patients undergoing off-pump coronary artery bypass grafting (OPCAB) versus on-pump CABG (on-CAB).

Methods: Data of 704 consecutive patients were analyzed.
