Importance of blood pressure control in Kawasaki disease with expanded multiple giant coronary aneurysms with a 32 mm maximum diameter: a case report.

Background: Ruptured coronary artery aneurysm is rare, but the most serious complications of an acute phase of Kawasaki disease (KD) with giant coronary artery aneurysm (GCAA). Progressive or super GCAA, which rapidly dilates and continue to increase over a diameter of 10 mm, are more susceptible to rupture.

Case Summary: We report the case of a 6-year-old boy with KD who had multiple super GCAAs with a high risk of GCAA rupture.

Transcarotid balloon aortic valvuloplasty for critical aortic stenosis in an infant weighing 890 g.

We report the smallest case of the balloon aortic valvuloplasty via a carotid artery. A baby boy weighing 890 g suffered from a severe aortic stenosis. Balloon aortic valvuloplasty using a TMP-Ped 4-mm balloon catheter succeeded in resolving severe aortic stenosis without any complications.

A Case of Kawasaki Disease Accompanied by Encephalitis and Several Kinds of Arrhythmia during the Acute Phase.

Although central nervous system complications occasionally accompany during the acute phase of Kawasaki disease, clinically problematic arrhythmia is quite rare. We report a case accompanied by encephalitis and several kinds of problematic arrhythmia. Following the diagnosis of Taussig-Bing anomaly and coarctation of the aorta, the patient underwent aortic arch reconstruction, an arterial switch operation, and ventricular septal defect closure.

Intractable Back Pain After Coil Embolization of Giant Veno-Venous Collaterals in a Patient With Fontan Circulation.

Veno-venous collaterals are sometimes seen in patients after the Fontan procedure. A 28-year-old female with tricuspid atresia who underwent the Fontan procedure had oxygen desaturation due to a giant veno-venous collateral. Coil embolization was performed for the collateral.

Siblings with Idiopathic Left Atrial Appendage Ostial Stenosis and Cor Triatriatum.

Isolated left atrial appendage (LAA) ostial stenosis is a very rare entity found coincidentally in adults by transesophageal echocardiography. A 3-month-old healthy infant was suspected as having cor triatriatum. His brother had a history of surgical treatment of cor triatriatum.
