A case of familial hypercholesterolemia; secession from LDL-apheresis by the drug treatment with potent statin and resin.

Low density lipoprotein (LDL)-apheresis is a useful tool for the treatment of familial hypercholesterolemia (FH) with coronary artery disease (CAD). However, it gives economic, physical and mental burdens for the patients. We reports a case of FH in whom LDL-apheresis treatment was seceded with drug treatment with a potent statin and bile acid-sequestering resin. A 54-year-old woman was admitted for evaluation of atherosclerotic lesion after 4 years of LDL-apheresis and 1 year of drug medication with a potent statin, atorvastatin and resin, cholestimide with coronary angiography. She had been diagnosed as heterozygous FH when she was 46 years old. Oral medication was initiated at the outpatient clinic. LDL-cholesterol (C) level was not successfully controlled despite the administration of a statin, pravastatin, a fibrate, clinofibrate and probucol at maximum doses Concomitantly. Therefore, as combination therapy, LDL-apheresis was introduced in May 1997. However, the patient strongly complained of the economic, physical, and mental burdens of LDL-apheresis and requested discontinuation of apheresis. Therefore, LDL-apheresis was discontinued in July 2000, and oral medication was subsequently changed to a combination of atorvastatin and cholestimide, resulting in successful control of serum LDL-C level by oral medication alone. We compared coronary arteriographic findings between 1997 and 2001. No advancement of lesions was observed. We think that strong drug treatment can secede from the LDL-apheresis for treatment of patients with FH.

Detection of right to left shunting through a patent foramen ovale in Japanese patients with ischemic stroke by transesophageal echocardiography using a standardized Valsalva maneuver.

We attempted to clarify the usefulness of transesophageal echocardiography performed using a standardized Valsalva maneuver to detect the presence of a patent foramen ovale in Japanese patients with ischemic stroke. Four hundred ninety six patients with ischemic stroke who were admitted to the Yokohama City Brain and Stroke Center between September 1999 and February 2002 were enrolled for the study. All the enrolled patients underwent transesophageal echocardiography with contrast injection and color Doppler imaging. During the procedure, a standardized Valsalva maneuver was performed to induce right to left shunting through a patent foramen ovale. Other related structural abnormalities, such as atrial septal aneurysm and the Chiari network anomaly, were also detected by the test. Transesophageal echocardiography without the Valsalva maneuver revealed a functional right to left communication in only 8.2% of the ischemic stroke patients, whereas the procedure conducted using a standardized Valsalva maneuver to provoke shunting revealed a patent foramen ovale in 15.3% of the patients. The presence of an atrial septal aneurysm or the Chiari network anomaly was not sensitive or specific enough to predict the presence of a patent foramen ovale as diagnosed by transesophageal echocardiography using the standardized Valsalva maneuver. Our results suggest that the standardized Valsalva maneuver is a safe and useful technique to detect the presence of a patent foramen ovale, which is potentially known to be associated with paradoxical embolism.
