ABSTRACT
Papillary fibroelastoma (PFE) is the second most common type of benign cardiac tumor after myxoma, and is most commonly found in the left side of the heart. In this study, we report a case of PFE located in the tricuspid valve chordae. The patient was a 65-year-old woman in whom a heart murmur was detected during a routine medical examination. A follow-up examination identified a cardiac tumor, and she was subsequently referred to our medical department. Echocardiography and contrast-enhanced computed tomography indicated a mobile mass of approximately 1 cm in the right ventricle, and she was determined to be a candidate for surgery. After cardiopulmonary bypass, we instigated cardioplegic arrest, made an incision in the right atrium, and observed the right ventricle through the tricuspid valve. We observed a yellowish sea-anemone-like mass approximately 9 mm from the chordae of the anterior leaflet of the tricuspid valve. Thus, the mass was resected with the chordae and tricuspid annuloplasty. Postoperative progress was satisfactory, and the subject was discharged on the 19th day of hospitalization. Histopathological examination indicated a mixture of thick fibrous and adipose tissues, which led to the diagnosis of PFE. PFE is a relatively rare disease that comprises 8% of primary cardiac tumors. IA often occurs in the left heart and can cause cerebral infarction, myocardial infarction, and other symptoms of embolism. However, because small masses and those that occur in the right heart are not accompanied by clinical symptoms, such cases are often discovered during routine echocardiography. The present study reports a case of PFE that occurred in the tricuspid valve chordae that was diagnosed via echocardiography.
ABSTRACT
The patient was a 63-year-old man with a history of multiple mononeuritis with hypergammaglobulinemia since 1980. The symptoms gradually worsened, and he had been bed-ridden since 1992. On February 28, 1997, he had sudden dyspnea after defecation. Echocardiography demonstrated a large thrombus in the right atrium and the right ventricle. Enhanced chest computed tomography revealed thrombi in the bilateral pulmonary arteries. The patient was considered to have acute pulmonary thromboembolism, and an emergency operation was indicated. Thrombectomy was performed under extracorporeal circulation through a median sternotomy. No thrombi were found in the right atrium or the right ventricle, and thrombi in the bilateral pulmonary arteries were removed completely. Four days after the operation, a Greenfield filter was implanted in the vena cava inferior because venography detected a thrombus in the right common iliac vein. The postoperative course was uneventful. No pulmonary rethromboembolisms were noticed after the operation. The long duration of being bed-ridden seemed to be the chief cause of thrombosis in the deep veins, and hyperviscosity due to hypergammaglobulinemia may have caused hyperthrombogenicity.
ABSTRACT
The patient was a 52-year-old man with a history of antiphospholipid syndrome (APS), renal dysfunction and myasthenia gravis (MG). On May 2, 1998, he had sudden chest pain while sleeping. Enhanced computed tomography revealed acute aortic dissection (DeBakey type I). We performed emergency graft replacement of the ascending aorta and the aortic arch under extracorporeal circulation. Because of perioperative anuria, we used peritoneal dialysis (PD) just after the operation. Two days after the operation, we performed re-intubation nine hours after the extubation of the tracheal tube, and performed re-extubation three days later. For a while, his postoperative course was uneventful, but because of gradual worsening of APS, we administered more prednisolone, but 74 days after the operation, he died of multiple organ failure caused by an opportunistic infection, sepsis, and disseminated intravascular coagulation. This was very rare case of acute aortic dissection with MG and APS. After administration of more glucocorticoids, it is important to be wary of opportunistic infections.
ABSTRACT
A 69-year-old man in whom two stents had been implanted on segments 6 and 7 was admitted to our hospital with acute myocardial infarction (AMI). Coronary angiography suggested a total occlusion of the left anterior descending (LAD) between two stents. Percutaneous transluminal coronary angioplasty (PTCA) was performed, but it made an acute coronary occlusion due to a dissection of left main trunk (LMT). As cardiogenic shock occurred, he was put on percutaneous cardioplumonary support (PCPS), and a perfusion catheter was introduced to the LAD and a guide wire to the circumflex (Cx). Emergency coronary artery bypass grafting (CABG) was performed on cardioplumonary bypass (CPB). First, an SVG was grafted to the LAD on ventricular fibrillation, and the other SVG was grafted to segment 13 on cardiac arrest after the perfusion catheter and guide wire was removed. This method allowed this operation to be performed with suitable myocardial protection.
ABSTRACT
Direct coronary artery reimplantation to the aorta and mitral valve repair were successfully performed in a 29-year-old female with Bland-White-Garland syndrome (BWG syndrome). Under cardiopulmonary bypass, the main pulmonary artery was completely transected and the left coronary artery was excised with a cuff of pulmonary artery wall. Then the left coronary artery was directly anastomosed to the ascending aorta. Mitral regurgitation was repaired with valvulo-annuloplasty. The post operative course was excellent.
ABSTRACT
A 76-year-old man was admitted to our hospital because of sudden upper abdominal pain and shock status. The patient had undergone Miles' procedure with a colostomy on the left lower abdomen due to rectal cancer at the age of 70 years. CT scans revealed a thoracoabdominal aortic aneurysm. In view of the clinical findings, ruptured aneurysm requiring emergent operation was diagnosed. A left spiral skin incision was made, keeping away from the colostomy. An extraperitoneal approach was selected. The thoracoabdominal aorta was replaced with an artificial graft under partial extracorporeal circulation with femoral arterial and venous cannulation. The postoperative course was uneventful. No paraplegia occurred in spite of no reconstruction of the intercostal arteries due to severe atherosclerotic changes of the aortic wall. The fact that bleeding due to ruptured aneurysm was localized in the extrapleural and extrapritoneal spaces seemed to be an advantageous factor for the success in this case.
ABSTRACT
Seven patients underwent surgical repair of the distal aortic arch aneurysm from January 1990 to October 1997. They were 5 men and 2 women ranging from 63 to 78 years of age (mean, 72.7 years). All patients were operated with a median sternotomy only. There was one operative death, which was ruptured case. However, there were no major complications in non-ruptured cases. This retrospective study suggests that it is possible to repair the distal aortic arch aneurysm through a median sternotomy approach alone, when 1) descending aorta originates with normal size just distal to sacciform aneurysm, 2) the maximum diameter of the aneurysm is over 70mm and 3) distal involvement of the aneurysm does not extend beyond the bifurcation of the trachea. It is useful to retract descending aorta proximally by three threads with pledget for distal anastomosis in inclusion technique.
ABSTRACT
A 47-year-old woman complained of dyspnea on exertion. Ultrasonic cardiography revealed coronary sinus type atrial septal defect. At operation, the drainage veins to the left atrium from the coronary arteries were observed but no anomalies of the vena cave or any other veins were observed. The defect was closed with a pericardial patch under cardiopulmonary bypass. The post-operative course was uneventful. Coronary arteriography performed on the 14th post operative day confirmed that the coronary veins drained individually into the corresponding atria. Unroofed coronary sinus is rare and difficult to diagnose prior to operation. Ultrasonic cardiography and coronary arteriography are considered useful for preoperative diagnosis.
