Predictive risk factors of acute kidney injury after on-pump coronary artery bypass grafting.

Background: Acute kidney injury (AKI) is a common complication after coronary artery bypass grafting (CABG) and increases the risk of short and long-term morbidity and mortality. The aim of our study is to identify preoperative and intraoperative risk factors for development of AKI after primary isolated on-pump CABG.

Methods: In the retrospective study, 210 consecutive patients who underwent primary isolated on-pump CABG from January 2007 to March 2016 were included.

Late cardiac tamponade following Nuss procedure for pectus excavatum.

The Nuss procedure is a recently developed technique for correction of pectus excavatum. A 23-year-old female patient presented at our emergency department with clinical signs of cardiac tamponade, which required an emergency procedure. Sixteen months ago, she underwent the Nuss procedure with a single bar.

Rupture of right sinus of Valsalva aneurysm protruding into the pulmonary artery with aortic and pulmonary valve endocarditis.

Rupture of right sinus of Valsalva aneurysm (SVA) protruding into the pulmonary artery with aortic and pulmonary valve endocarditis is rare. A 42-year-old man was admitted with fever and dyspnea. He was diagnosed with right sinus of Valsalva rupture with ventricular septal defect (VSD) and vegetation on both aortic and pulmonary valves.

Electrocautery-Ignited Surgical Field Fire Caused by a High Oxygen Level during Tracheostomy.

Tracheostomy is a relatively common surgical procedure that is performed easily in an operating room or intensive care unit. Open tracheostomy is needed in patients requiring prolonged ventilation when percutaneous tracheostomy is inappropriate. Sometimes, it is difficult to achieve bleeding control in the peritracheal soft tissue, and in such cases, we usually use diathermy.

The rupture of atrioventricular groove after mitral valve replacement in an elderly patient.

Rupture of the left ventricle after mitral valve replacement, although infrequent, may be a highly lethal complication. This report describes the early diagnosis and successful repair of rupture of atrioventricular groove in an elderly patient who underwent mitral valve replacement.

Acute thrombosis of bioprosthetic mitral valve.

We report a case of acute thrombosis of bioprosthetic mitral valve in a 59 year-old Korean female, who underwent a mitral valve replacement with a 25 mm Carpentier - Edwards PERIMOUNT Plus bioprosthesis (Edwards Lifesciences, Inc.; Irvine, CA, USA) and a mini-Maze procedure for correction of mitral stenosis (MS) and atrial fibrillation (AF). On the 10th postoperative day, the patient began to complain of increasing dyspnea and general malaise.

Surgery for subclavian arteriovenous fistula with ruptured pseudoaneurysm using total circulatory arrest.

Subclavian arteriovenous (AV) fistula is an uncommon disease and rarely occurs secondary to injury. We herein report a case of a ruptured pseudoaneurysm with a subclavian AV fistula caused by clavicle fixation. In cases of a large ruptured pseudoaneurysm with a massive surrounding hematoma, bleeding control and vessel repair is very difficult.

Pulmonary artery intimal sarcoma: poor 18F-fluorodeoxyglucose uptake in positron emission computed tomography.

Intimal sarcoma of the pulmonary artery is a rare malignant tumor that may be misdiagnosed as chronic pulmonary thromboembolism, even if various imaging techniques are used. We report a case of a 58-year-old man with pulmonary artery intimal sarcoma.18F-fleuorodeoxyglucose (FDG) uptake was poor in the mass of the pulmonary artery, and no other hypermetabolic lesions were noted elsewhere.

Multiple paravalvular leak 17 years after a second mitral valve replacement.

Paravalvular leak (PVL) after prosthetic valve implantation is a significant complication and it usually occurs early in the postoperative period. We report a case of multiple PVL 17 years after the second mitral valve replacement without evidence of infection. The valve sutures were neither cut nor loosened.

Acute Type II Aortic Dissection with Severe Aortic Regurgitation and Chronic Descending Aortic Dissection in Pregnant Patient with Marfan Syndrome.

Aortic dilatation and dissection are severe complications during pregnancy that can be fatal to both the mother and the fetus. The risks of these complications are especially high in pregnant patients with Marfan syndrome; however, incidents of descending aortic dissection are very rare. This case report involves a successful Bentall procedure for and recovery from a rare aortic dissection in a pregnant Marfan patient who developed acute type II aortic dissection with severe aortic regurgitation and chronic descending aortic dissection immediately after Cesarean section.

Simultaneous Aortic and Tricuspid Valve Endocarditis due to Complication of Sinus of Valsalva Rupture.

We experienced a case of ruptured aneurysm of the sinus of Valsalva, and this resulted in simultaneous aortic and tricuspid valve endocarditis through a shunt. The echocardiography showed a ruptured sinus of Valsalva aneurysm to the right atrium with a shunt. The aortic non-coronary cusp was fibro-thickened with vegetation.

Acute post-cardiopulmonary bypass left atrial thrombosis after mitral valvuloplasty and left atrial thrombectomy.

A patient with mitral stenosis and multiple left atrial thrombi underwent valvuloplasty and thrombectomy. While closing the sternum after completing the cardiopulmonary bypass, a new left atrial thrombus was detected by transesophageal echocardiography. We used heparin for the prevention of new thrombus formation and closed the wound after meticulous bleeding control.

Surgery for pseudoaneurysm of the ascending aorta under moderate hypothermia.

Pseudoaneurysm of the ascending aorta is a rare complication after cardiac surgery. Particularly, pseudoaneurysm due to postoperative infection in the ascending aorta requires surgical treatment with antibiotics. If a large sized pseudoaneurysm is located at the retrosternal space, then there is a very high risk of massive bleeding from rupture during performance of resternotomy.

Pulmonary valve leaflet extension with bovine pericardium: for treatment of pulmonary insufficiency.

Using a homograft in a pulmonic area is sometimes inadvisable due to the lack of optimal graft materials. We report a case of pulmonary valve insufficiency that we treated by leaflet extension using the commercially available E-Leafcon template and bovine pericardium. We suggest that this method can be an acceptable alternative for treating pulmonary valve insufficiency because the pulmonary valve area is similar to that of the aortic valve (for which application the template was designed).

Misplaced central venous catheter in the jugular venous arch exposed during dissection before sternotomy.

Subclavian vein catheterization rarely results in misplacement of the central venous catheter (CVC) into the jugular venous arch (JVA). We present a case of misplacement of the CVC into the JVA during cardiac surgery.

Anomalous origin of left pulmonary artery from aorta with atrial septal defect.

Anomalous origin of left pulmonary artery (ALPA) from aorta with atrial septal defect (ASD) is a rare congenital cardiac malformation. We report a case of ALPA from the aorta with ASD in a 1.8-kg baby.
