10-year results of On-X bileaflet mechanical heart valve in the aortic position: low target INR regimen in Japanese.

Objectives: This study was designed to establish clinical outcomes after aortic valve replacement (AVR) with On-X bileaflet mechanical heart valve.

Methods: Between 2006 and 2014, AVR was performed to 686 patients. Of them, 78 patients using On-X valve were enrolled.

A reoperation of thrombosed On-X valve detected by multidetector-row computed tomography.

A 62-year-old female patient underwent mitral valve replacement with a 31/33-mm On-X valve for ischemic mitral valve regurgitation. Three months later, transthoracic echocardiography incidentally showed a blocked leaflet with 6 mmHg of mean pressure gradient and 2.4 cm(2) of mitral valve orifice area.

Mid-term results of 17-mm St. Jude Medical Regent prosthetic valves in elder patients with small aortic annuli: comparison with 19-mm bioprosthetic valves.

This study was designed to compare the mid-term outcomes after aortic valve replacement (AVR) between 17-mm mechanical heart valves (MV) and 19-mm bioprosthetic valves (BV) in elderly patients with small aortic annuli. Between 2000 and 2011, 127 consecutive patients (mean age 79 years; 87 % female) underwent AVR for aortic valve stenosis with a small aortic annulus. 19-mm BV (n = 67) was implanted.

Evaluation of advancing the standard valve dysfunction by multidetector-row CT.

We evaluated the diagnostic usefulness of electrocardiographically gated multidetector-row computed tomography (MDCT) for prosthetic valve dysfunction (PVD) of an ATS valve. Twenty-four patients underwent MDCT following echocardiography and cineradiography. Echocardiography and cineradiography showed normal valve function in 17 patients and PVD in 7.

Diagnosis of structural deterioration in an aortic bioprosthetic valve by multidetector row computed tomography: report of a case.

A 32-year-old female patient presented with shortness of breath. The patient had received aortic valve replacement with a 25-mm bioprosthetic valve at the age of 22, and had had two babies, postoperatively. Ten years later, echocardiography showed the calcifi ed bioprosthetic valve with a high peak pressure gradient (70 mmHg) and a reduced valve orifice area (0.

Postinfarct cardiac free wall rupture detected by multidetector computed tomography.

Cardiac free wall rupture after myocardial infarction is one of the life-threatening complications, which often results in sudden onset of cardiogenic shock caused by cardiac tamponade. Multidetector computed tomography (MDCT) provides valuable information in any clinical setting. There have been a few case reports on detecting cardiac rupture by means of CT.

Early postoperative recovery by chronic dialysis patients after coronary artery bypass grafting.

Objective: A faster start at rehabilitation has been a great benefit in reducing complications and costs after coronary artery bypass grafting (CABG). We studied early postoperative recovery from CABG in dialysis patients.

Methods: From January 2001 to May 2006, a total of 401 patients underwent isolated CABG at our institution.

Successful combined treatment of primary cardiac malignant lymphoma with urgent cardiac operation and chemotherapy.

A 56-year-old man, suffering from rapidly worsening general fatigue, dyspnea on exercise and epigastralgia, was referred for evaluation and treatment of a cardiac tumor. Transthoracic echocardiography showed a 6-cm large mass occupying both the right ventricle and atrium. Gallium scintigraphy showed high uptake in the tumor site.
