[Surgical Treatment of Acute Infective Endocarditis after Transcatheter Aortic Valve Replacement].

Infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) is a rare complication, but has a high mortality. An 86-year-old female with symptomatic severe aortic stenosis underwent TAVR at our hospital and she was discharged without complication after 10 days. She was readmitted with high fever and acute heart failure 1 month later.

In situ coronary-coronary bypass grafting for a huge left coronary aneurysm.

Surgical treatment for an atherosclerotic huge coronary aneurysm is very rare. We have reported 58 years old male who had a huge growing aneurysm in left circumflex coronary artery and underwent aneurysmectomy and coronary-coronary bypass grafting with saphenous vein.

Surgical treatment of cardiac myxosarcoma.

A 36-year-old man suffering from exertional dyspnea was admitted to our hospital. An echocardiogram showed a left atrial tumor, which was excised via the left atrial approach. Histological examination of the surgical specimen revealed that it was a myxosarcoma.

Initial clinical experience with the Heartstring.

Objective: The Heartstring is one of the devices that enable proximal anastomosis without clamping the aorta. We have applied the device not only to low-risk patients with normal aortas but also to high-risk patients with diseased aortas. The purpose of this study was to investigate the initial outcomes of using this device.

Aortic valve myxoma mimicking vegetation: report of a case.

We report a case of cardiac myxoma of the aortic valve. To our knowledge, this represents only the seventh such case ever documented. A 61-year-old woman underwent an echocardiography to screen for hypertensive-diabetic cardiac complications, which showed a mass on her aortic valve.

Re-reconstruction of visceral arteries with thoracoabdominal aortic replacement using a branched graft.

A 44-year-old man, unaffected by Marfan's syndrome, had previously undergone thoracoabdominal replacement for a chronic, type B dissecting aneurysm. Reconstruction of the visceral arteries was performed using an island technique. However, approximately 3 years after the operation, the reconstructed part of the aorta containing the visceral arteries became dilated and an aneurysm formed.

Sevoflurane metabolite production in a small cohort of coronary artery bypass graft surgery patients.

Objective: To determine hepatic and renal effects of hexafluoroisopropanol in patients undergoing coronary artery bypass graft surgery under sevoflurane anesthesia.

Design: Prospective, clinical comparison.

Setting: University hospital.
