The findings suggest that IVMP is an effective additional treatment for IVIG-resistant KD. However, there was a tendency for fever to recur later in IVMP-resistant patients, which could potentially delay the therapeutic decision-making process.

In KD, myocarditis develops even earlier than epicardial coronary arteritis; it peaks by disease day 10 and then disappears gradually after day 20. The myocarditis is distributed unevenly, ranging from the entire heart to the epicardial layer of the base of the heart.

In cases in which patients show significant localized stenosis as a result of Kawasaki disease, PTCA should be attempted within 6 to 8 years of the onset of the disease. Additionally, intravascular ultrasound imaging was found to be a useful tool for evaluating internal morphology before and after PTCA. In older patients with coronary calcification, other alternatives to PTCA, such as the use of a rotablator or an atherectomy catheter, should be considered.

Background: In patients with tetralogy of Fallot (TOF), left ventricular (LV) dysfunction is an important factor associated with poor clinical outcome. Objective: The purpose of this study was to investigate the torsion and multidirectional strain of the LV in patients with TOF. Methods: Echocardiographic images were prospectively acquired in 29 patients who underwent TOF repair (age range, 5–25 years) and in 29 normal controls. Torsion and circumferential and longitudinal strain of the LV were assessed using speckle tracking imaging. Results: The torsion in patients was smaller compared to that in the controls due to small apical rotation and/or inverse basal rotation (P < 0.01). Torsion and untwisting rates decreased with increasing age (R = 0.37, P < 0.05). Basal circumferential strain and strain rate (SR) at systole and diastole decreased with age (R = 0.58; R = 0.57; R = 0.57, all P < 0.001) and were smaller in patients compared to those in the controls (all P < 0.01). Septal longitudinal strain and SR at systole and diastole decreased with age (R = 0.52; R = 0.62; R = 0.71, all P < 0.001) and were smaller than those of the controls (P < 0.01), although lateral longitudinal strain and SR were relatively maintained. Conclusion: Abnormal torsion and strain pattern of the LV were observed in patients without symptoms of cardiac failure. Assessment of torsion and strain is a very sensitive tool to detect the early deterioration of LV function in patients with TOF. (Echocardiography 2011;28:720‐729)

The results show that enteric protein loss begins before the appearance of hypoproteinemia in patients after a modified Fontan operation, and that the measurement of fecal alpha1-antitrypsin concentrations in random stool samples is useful as an early indicator. To watch for the development of PLE after Fontan operation, it may be important to perform longitudinal follow-up examinations of enteric protein loss by measuring fecal alpha1-antitrypsin concentrations early in the postoperative period.
