[Simultaneous aortic root and total arch graft replacement in a patient with aortitis syndrome].

The patient was a 45-year-old female diagnosed with aortitis syndrome and aortic regurgitation (AR). She had been taking steroid therapy since 1975. She had recently developed congestive heart failure due to AR while both the ascending aorta and aortic arch were enlarged.

[Surgical treatment of mycotic coronary artery aneurysm associated with infective endocarditis: a case report].

53-year-old male was introduced our hospital for treatment of his infective endocarditis and congestive heart failure. Further evaluation revealed massive destruction of the mitral valve and aneurysm of the right coronary artery. We carried out an operation of aneurysmectomy and CABG with RGEA for coronary artery, and MVR using 29 mm SJM valve.

[The graft replacement of the patient with aortic arch aneurysm and thrombosed aortic dissection].

The patient was male and aged 68 years and complained of dyspnea and chest pain. He was pointed out aortic arch dilatation on chest X-ray and CT demonstrated aortic arch aneurysm accompanied with acute type IIIb aortic dissection. One month later after anti-hypertensive therapy, the false lumen of aortic dissection was closed with thrombus.

[Aortic root replacement in twin Marfan patients].

We have performed aortic root replacement in twin Marfan patients. They were male and aged 33 years at the times of the operations. One had pneumonia but the other had no complaints.

[Two cases of surgically treated malignant primary tumors originated from the pulmonary artery].

Two surgically treated cases of malignant tumors which originated inside of the pulmonary artery were reported. A 62-year-old female with an undifferentiated sarcoma and a 24-year-old male with a malignant fibrous histiocytoma were successively operated on in two months for the release of their chief complaints of exertional dyspnea. In the first case the tumor was resected completely, although partially resected in the second case.

[A case of left ventricular-right atrial communication complicated with aortic regurgitation caused by active infective endocarditis].

A 63-year-old man with cough and shortness of breath was diagnosed to have active infective endocarditis resulting in acute pulmonary edema with aortic regurgitation caused by a huge vegetation on the noncoronary cusp and left ventricular-right atrial (LV-RA) communication which were demonstrated by the echocardiogram and color doppler method. The LV-RA communication located at the atrioventricular portion of the membranous septum was closed with GoreTex patch through the right atrium combined with the aortic valve replacement with a bileaflet mechanical valve in emergency. The bacteriological studies demonstrated staphylococcus epidermidis.

[Successful surgical treatment in a case of complete rupture of the posterior papillary muscle of the mitral valve caused by infective endocarditis].

Forty three year-old male who had cough and easy fatigability since three weeks prior to admission was diagnosed to have acute pulmonary edema with severe mitral regurgitation caused by active infective endocarditis. Transesophageal echocardiograms under the endotracheal intubation for controlled respiration suggested rupture of the posterior papillary muscle of the mitral valve and the emergency surgical treatment was performed. Intraoperatively the total rupture of the posterior papillary muscle was confirmed and mitral valve replacement was carried out with a SJM prosthetic valve.
