A 76-year-old woman with hypertension was admitted to the hospital complaints of chest pain and dyspnea. An echocardiogram pulmonary computed tomography angiography showed right atrial myxoma complicated thromboembolism. operation resect embolism recommended; however, patient refused discharged anticoagulation therapy. Two years later, she developed Radiological studies echocardiography similar results previous findings. The underwent mediastinotomy resection embolectomy. As there are few...
Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and clarify sustained long-term effects surgery by comparing preoperative, postoperative, follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for mean (median) period 6.8±5.4 years (4.2 years).We retrospectively reviewed 27 cases massive or submassive acute PTE from 2003 2016. Immediate assessed on basis 30-day mortality,...
Transient myocardial ischemia during cardiac surgery causes a loss of energy sources, contractile depression, and accumulation metabolites H+ ion resulting in intracellular acidosis. The reperfusion following ischemic cardioplegia recovers pH, activates Na+-H+ exchange Na+-Ca2+ transports consequently produces Ca2+ overload, which yields cell death. Among the various entry pathways, exchanger is known to play one major roles ischemia/reperfusion cardioplegia. Consequently, information on...
A 51-year-old male was admitted to the hospital with complaints of fever and hemoptysis. After evaluation focus, he diagnosed pulmonary valve infective endocarditis. Thus replacement antibiotics therapy were performed discharged. He brought emergency unit presenting a high (>39℃) general weakness 6 months after initial operation. The echocardiography revealed prosthetic Therefore, redo-pulmonary using valved conduit in Rastelli fashion because risk arterial wall injury recurrent endocarditis...
It has been proposed that Ca(2+)-activated K+ channels play an essential role in maintaining vascular tone during stretch of blood vessel. However, the underlying mechanism stretch-induced change channel activities are still unknown. The present experiment was designed to investigate effect membrane on these whose activity measured from rabbit coronary smooth muscle cells using a patch clamp technique. were identified by their Ca2+ and voltage dependencies its large conductances as other...
우리나라 여성의 유방암은 서구화에 따라서 두 번째로 흔한 암으로 1999년 한국유방암등록 연례 보고서에 따르 면 전체 암 발생의 14.7%를 차지하였으며 식생활 의 변화와 함께 점차 증가하고 있다.(1) 유방암의 완치를 위해서는 유방 변형근치절제술 또는 부분절제술 및 술 후 항암화학요법과 방사선 치료가 시행되는데 각각 치 료방법에 따라 국소재발률의 차이는 있지만 사망률에는 영향을 미치지 못한다.(2,3) 즉, 유방암 환자들에서 결국 보조적인 치료에도 불구하고 많은 환자들이 재발로 인하여 사망에 이르게 되는데 이는 국소재발로 인한 것보 다는 폐, 골, 간, 뇌 등 전신전이가 주를 이룬다. 보 조요법을 시행받지 않을 경우, 액와림프절에 전이가 있는 경우에는 약 75%, 없는 30%가 전신 전이로 사망하게 된다. 이와 같은 원격전이의 재 발 원인은 진단 당시 이미 존재하는 미세전이에 기인하는 것으로 알려져 있다.(2,3) 수술 미세 전이에 대한 전신적인 생존율을 의미 있게 증가시...
The dehiscence of saphenous vein grafts (SVGs) is a rare, often fatal, complication coronary artery bypass grafting (CABG).We present the case 57-year-old man who underwent hemiarch graft interposition and CABG for Stanford type A aortic dissection.Five months after discharge, patient developed streptococcal sepsis caused by hemodialysis catheter.Complete rupture proximal anastomoses veins containment obliterated pericardial cavity was observed 25 initial operation.The successfully treated...
Primary pericardial mesothelioma is a rare tumor of mesodermal origin that infrequently diagnosed antemortem and survival short. A 60 year old male case (epitheloid type) reported. He was admitted to Yeungnam University Hospital because chest pain, dyspnea, orthopnea nonproductive cough. Chest x-ray suggested effusion. 2-D echocardiography showed echo free spaces massive effusion areas thick hyperrefractile echoes arising from the pericardium. Pericardiocentesis attempted aspirated fluid...
The congenital tracheoesophageal fistula without atresia of the esophagus is considered a rare variant, and literature concerned to atresia, little in adult especially. 22-year-old male was admitted Yeungnam University Hospital with his chief complaints weight loss (6kg/6 months), abdominal discomfort, intermittent coughing. diagnosis made by endoscopy esophagography. 1.5cm diameter, 0.5cm length. level around second thoracic vertebra. operation performed transpleurally through right third...
Ventricular septal defect is most common congenital cardiac anomaly in Korea and worldwide. And its clinical spectrum well known. The anatomic classification had been undertaken by several authors, but recently Dr. Soto Anderson's widely used instead of Kirklin's it. From April. 1984 to December 1986, 99 cases ventricular defects taken surgical repair under direct vision using conventional cardiopulmonary bypass technique at Yeungnam university hospital. was similar other hospital, the...
