Association between angiotensin I-converting enzyme gene insertion/deletion polymorphism and risk of rheumatic heart disease.

Jpn Heart J 2004 Nov;45(6):949-57

Division of Cardiology, Department of Medicine, China Medical University Hospital, Taichung 404, Taiwan, ROC.

Scarring and collagen deposition in the valves and destruction of myocytes may result from the combined effects of a smoldering rheumatic process and a constant trauma to the mitral valve or aortic valve by the turbulent flow in rheumatic heart disease (RHD). It has been suggested that angiotensin I-converting enzyme (ACE) may be responsible for the increased valvular fibrosis and calcification in the pathogenesis of RHD. However, the role of ACE genetic variant in RHD has not been studied among the Chinese population in Taiwan. Read More

A coronary artery fistula with saccular aneurysm mimicking a right atrial cystic mass.

Jpn Heart J 2004 Jul;45(4):697-702

Department of Cardiology, Ajou University School of Medicine, Suwon, Korea..

A 16 year-old Korean girl with cardiomegaly was found to have a "right atrial cystic mass" on transthoracic echocardiography. An unusual cystic structure made the diagnosis difficult. However, transesophageal echocardiography and multidetector computed tomography revealed a coronary artery fistula with a distal saccular aneurysm involving the interatrial septum and draining into the right atrium.

Experience with nifekalant hydrochloride in a patient with ischemic cardiomyopathy and severe ventricular dysfunction after dor operation.

Jpn Heart J 2004 Jul;45(4):691-5

Department of Cardiovascular Surgery, Kawasaki Municipal Hospital, Japan.

A 52-year-old male with ischemic cardiomyopathy and severe ventricular dysfunction underwent coronary artery bypass grafting and left ventricular reconstruction (Dor operation). The patient developed acute onset of incessant ventricular tachycardia in the early postoperative period that was refractory to therapy with class I antiarrhythmic agents, and multiple attempts at electrical cardioversion were required. A combination of intravenous nifekalant hydrochloride and enteral amiodarone was elected as treatment for this recurrent incessant ventricular tachycardia. Read More

Fabry disease female proband with clinical manifestations similar to hypertrophic cardiomyopathy.

Jpn Heart J 2004 Jul;45(4):685-9

Department of Internal Medicine, Osaka City University Medical School, Japan.

Fabry's disease is an X-linked inborn error of glycosphingolipid catabolism, resulting from a deficiency in alpha-galactosidase A (alpha-Gal A). A 56-year-old Japanese woman was at first suspected of having hypertrophic cardiomyopathy. The patient and her son had alpha-Gal A activity in leukocytes that was remarkably below the limit of controls. Read More

Anomalous right coronary artery originating from the distal left circumflex artery: single coronary artery with choronic atrial fibrillation.

Jpn Heart J 2004 Jul;45(4):679-83

Cardiovascular Division, Osaka National Hospital Japan.

This report describes a patient with a single coronary artery in whom the right coronary artery originated from the distal left circumflex artery. Single coronary artery is a rare congenital anomaly of the coronary circulation which is often associated with other congenital cardiac malformations. This anomaly is thought to be clinically significant especially in patients with atrial fibrillation, although no other associated cardiac anomaly was detected. Read More

Usefulness of a 6 fr right judkins catheter for mechanically extracting a massive intracoronary thrombus from an ectasic right coronary artery: a report on two different cases of thrombectomy.

Jpn Heart J 2004 Jul;45(4):673-8

Division of Cardiology, Saitama Cardiovascular and Respiratory Center, Japan.

In order to bail out the slow-flow phenomenon (slow flow) created by a massive thrombus in an ectasic right coronary artery, a thrombus was mechanically extracted with a 6 Fr right Judkins (JR) catheter, which proved to be more useful than a usual thrombectomy using a Rescue PT system catheter (Rescue). In case 1, the Rescue was used in combination with thrombolysis but failed to alleviate the slow flow that was implicated in a large infarction. On the other hand, in case 2, aggressive thrombectomy with a 6 Fr JR catheter with an 8 Fr Amplatz guiding catheter successfully extracted the massive intracoronary thrombus, restoring good coronary flow.

Synergistic effect of triptolide and tacrolimus on rat cardiac allotransplantation.

Jpn Heart J 2004 Jul;45(4):657-65

Department of Cardiovascular Surgery, Juntendo University School of Medicine, Tokyo, Japan.

Recent studies have shown that triptolide inhibits T cell activation through mechanisms different from those of cyclosporine A and tacrolimus and we postulated that triptolide might have a synergistic effect with tacrolimus to enhance immunosuppression. Using a F344 donor-to-Lewis recipient rat combination, we investigated the immunosuppressive effects of triptolide alone or in combination with tacrolimus on the survival of cardiac allografts. Recipients were treated with placebo, triptolide, tacrolimus, and triptolide in combination with tacrolimus at different doses. Read More
