Cardiopulmonary bypass preparation is mandatory in cardiac exploration for blunt cardiac injury patients: two case reports.

Treating cardiac injuries following blunt trauma to the chest requires thorough examination, accurate diagnosis, and therapeutic plan. We present two cases; pulmonary vein rupture and left atrial appendage laceration, both as a result of blunt chest trauma. Through these cases, our team learned the importance of maintaining hemodynamic stability during the examination of injured cardiac structures.

Importance of pulmonary valve morphology for pulmonary valve preservation in tetralogy of Fallot surgery: comparison of the echocardiographic parameters.

Background: The decision to use transannular patching (TAP) during tetralogy of Fallot (TOF) repair depends on the pulmonary valve annulus size; the z score of the pulmonary annulus is the most commonly used predictor. However, definitive results are not obtained with z scores as different z score data sets are used for different parameters.

Purpose: This study aimed to identify the echocardiographic and other key factors that warranted a change in the surgical method during TOF surgery.

Traumatic severe tricuspid regurgitation diagnosis after the progression of right ventricle function deterioration.

Traumatic tricuspid regurgitation is a rare complication of blunt cardiac injury and frequently misdiagnosed during the initial assessment. Unfortunately, it may be diagnosed after deterioration of right ventricle function, which may be fatal to the patient. Here, we report a case of a patient with blunt chest injury complicated by a diagnosis of traumatic severe tricuspid regurgitation after deterioration of the right ventricle function even after the patient was subjected to serum cardiac enzyme normalization.

Risk Factors Associated With Reintervention After Thoracic Endovascular Aortic Repair for Descending Aortic Pathologies.

Background:: Thoracic endovascular aortic repair (TEVAR) is associated with several short-term benefits, including reduced morbidity and mortality; however, the long-term durability of TEVAR and the need for secondary aortic reintervention remain unclear. We aimed to determine the adverse outcomes, including aortic reintervention, after TEVAR for thoracic aortic aneurysms and dissection.

Methods:: Between October 2009 and July 2016, 130 patients underwent TEVAR at Kyungpook National University Hospital.

Outcome of neonatal palliative procedure for pulmonary atresia with ventricular septal defect or tetralogy of Fallot with severe pulmonary stenosis: experience in a single tertiary center.

Purpose: The present study aimed to evaluate progression and prognosis according to the palliation method used in neonates and early infants aged 3 months or younger who were diagnosed with pulmonary atresia with ventricular septal defect (PA VSD) or tetralogy of Fallot (TOF) with severe pulmonary stenosis (PS) in a single tertiary hospital over a period of 12 years.

Methods: Twenty with PA VSD and 9 with TOF and severe PS needed initial palliation. Reintervention after initial palliation, complete repair, and progress were reviewed retrospectively.

Staged Management of a Ruptured Internal Mammary Artery Aneurysm.

The rupture of an internal mammary artery (IMA) aneurysm in a patient with type 1 neurofibromatosis (NF-1) is a rare but life-threatening complication requiring emergency management. A 50-year-old man with NF-1 was transferred to the emergency department of Kyungpook National University Hospital, where an IMA aneurysmal rupture and hemothorax were diagnosed and drained. The IMA aneurysmal rupture and hemothorax were successfully repaired by staged management combining endovascular treatment and subsequent video-assisted thoracoscopic surgery (VATS).

Fourth Recurrence of Cardiac Myxoma in a Patient with the Carney Complex.

Although cardiac myxoma is the most commonly encountered benign cardiac tumor in cardiac surgery practice, recurrent cardiac myxoma is very rare, is most commonly related to the Carney complex, and usually requires multiple cardiac operations with specific requirements in terms of perioperative management. In this report, we describe a patient who experienced the fourth recurrence of cardiac myxoma and review the diagnostic criteria of the Carney complex. This is the first report of such a case in Korea.

Early Manifestation of Supravalvular Aortic and Pulmonary Artery Stenosis in a Patient with Williams Syndrome.

Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is determined according to the progression of vascular stenosis.

Long-Term Follow-Up of the Half-Turned Truncal Switch Operation for Transposition of the Great Arteries with Ventricular Septal Defect and Pulmonary Stenosis.

The half-turned truncal switch (HTTS) operation has been reported as an alternative to the Rastelli or réparation à l'étage ventriculaire procedures. HTTS prevents left ventricular outflow tract (LVOT) obstruction in patients with complete transposition of the great arteries (TGA) with a ventricular septal defect (VSD) and pulmonary stenosis (PS), or in those with a Taussig-Bing anomaly with PS. The advantages of the HTTS procedure are avoidance of late LVOT or right ventricular outflow tract (RVOT) obstruction, and of overstretching of the pulmonary artery.

Surgical indications and results of mitral valve repair in pediatric patients with ventricular septal defects accompanied by mitral valve regurgitation.

Background: Ventricular septal defects (VSDs) can be accompanied by mitral regurgitation (MR) owing to chronic volume overload or mitral valve (MV) abnormalities. This study investigates the surgical indications, results, and natural course of pediatric VSD patients with MR.

Methods: One hundred seven patients (median age, 4.

Outcomes of nonpledgeted horizontal mattress suture technique for mitral valve replacement.

Background: Most surgeons favor the pledgeted suture technique for heart valve replacements because they believe it decreases the risk of paravalvular leak (PVL). We hypothesized that the use of nonpledgeted rather than pledgeted sutures during mitral valve replacement (MVR) may decrease the incidence of prosthetic valve endocarditis (PVE) and risk of a major PVL.

Methods: We analyzed 263 patients, divided into 175 patients who underwent MVR with nonpledgeted sutures from January 2003 to December 2013 and 88 patients who underwent MVR with pledgeted sutures from January 1995 to December 2001.

Outcome of inflammatory response after normothermia during cardiopulmonary bypass surgery in infants with isolated ventricular septal defect.

Purpose: A recent study analyzing several cytokines reported that long cardiopulmonary bypass (CPB) time and long aortic cross clamp (ACC) time were accompanied by enhanced postoperative inflammation, which contrasted with the modest influence of the degree of hypothermia. In this present study, we aimed to examine the effect of CPB temperature on the clinical outcome in infants undergoing repair of isolated ventricular septal defect (VSD).

Methods: Of the 212 infants with isolated VSD who underwent open heart surgery (OHS) between January 2001 and December 2010, 43 infants were enrolled.

Treatment of large arteriovenous malformation in right lower limb.

A 10-year-old boy with arteriovenous malformation (AVM) of the right lower limb was scheduled for an amputation of the affected limb. Limb amputation was necessary because of the ineffectiveness of previous sclerotherapy and the rapid progression of AVM causing pain and heart failure. Right hip disarticulation was considered the best option to improve his quality of life.

Operative management in a patient with scapulothoracic bursitis.

Scapulothoracic bursitis, an uncommon lesion, has been reported to be a painful disorder of scapulothoracic articulation. The articulation may become inflamed secondary to trauma when overused because of sports or work that requires repetitive or constant movement of the scapula against the posterior chest wall. The bursitis usually appears as a growing mass at the scapulothoracic interface and is often confused with a soft tissue tumor.

Placement of Endovascular Stent Graft in Acute Malperfusion Syndrome After Acute Type II Aortic Dissection.

Acute malperfusion syndrome is a serious complication of acute aortic dissection. A 76-year-old female patient was admitted with acute type B aortic dissection and developed renal malperfusion during medical therapy. We are reporting a clinically successful result from the thoracic endovascular aortic repair used for malperfusion syndrome that occurred by acute type B aortic dissection.

Comparison of the Outcomes between Axillary and Femoral Artery Cannulation for Acute Type A Aortic Dissection.

Background: At present, many surgeons prefer axillary artery cannulation because it facilitates antegrade cerebral perfusion and may diminish the risk of cerebral embolization. However, axillary artery cannulation has not been established as a routine procedure because there is controversy about its clinical advantage.

Materials And Methods: We examined 111 patients diagnosed with acute type A aortic dissection between January 2000 and December 2009.

Intrapericardial implantation of an implantable cardioverter-defibrillator in a child.

Implantable cardioverter defibrillator (ICD) can be a crucial therapeutic modality for pediatric patients with congenital heart disease, Brugada syndrome, long QT syndrome and cardiomyopathy. Because transvenous implantation of ICD is mostly unfeasible for pediatric patients due to anatomical and technical limitations, epicardial patch type or subcutaneous type ICD have been used. Implantation of these alternative ICDs, however, was reported to be frequently associated with significant complications.

Development of laser ruler in rigid laryngoscope.

Objectives: The objective of this study was to develop a new device that provides a simple, noninvasive method of measuring accurate lesion size while using an endoscope.

Methods: We developed a rigid laryngoscope with a built-in laser-ruler using a one-light emitting diode and an acrylic plate. The invention incorporates a built-in laser diode that projects an auto-parallel beam into the optical path of the rigid laryngoscope to form two spots in the field of view.

Long-term results of one-and-a-half ventricle repair in complex cardiac anomalies.

Objective: One-and-a-half ventricle repair is a surgical option for complex cardiac anomalies characterized by right-ventricle hypoplasia or dysfunction. The long-term result analyses or large clinical reviews are rare. The aim of this study is to evaluate the long-term functional results of this surgical procedure.

Pulmonary valve repair late after right ventricular outflow tract reconstruction in children and adolescents.

Here, we report our experience with pulmonary valve (PV) repair using neoleaflet implantation in children and adolescents. Between April 2005 and May 2009, 20 patients underwent late PV repair with neoleaflet implantation for pulmonary regurgitation (PR) after reconstruction of the right ventricular outflow tract at <18 years of age. In patients with sufficient remaining native PV leaflets, the neoleaflet was implanted with a polytetrafluoroethylene membrane or fresh autologous pericardium to coapt with the remaining native PV leaflets.

Novel treatment of first bite syndrome using botulinum toxin type A.

Background: First bite syndrome is the development of pain in the parotid region after the first bite of each meal and can be seen after surgery of the parapharyngeal space. The purpose of this study is to evaluate the efficacy of intraglandular injection of botulinum toxin type A (BTA) in patients with first bite syndrome.

Methods: Five patients with first bite syndrome developed after head and neck surgery were treated by injection of BTA into parotid gland.
