Chronological T-wave alternation before and after the onset of arrhythmogenic right ventricular cardiomyopathy.

Identification of arrhythmogenic right ventricular cardiomyopathy (ARVC) during childhood is challenging due to the lack of specific ECG manifestation. We report chronological ECG alteration before several years of the ARVC onset in two affected children. Their ECG at the age of 6 years was almost normal for their age, and their chronological ECGs exhibited inversion of T wave in inferior leads, which are typical for ARVC, developed at younger age than that in precordial leads.

Effect of Minocycline Pleurodesis in Infants With Refractory Chylothorax After Palliative Surgery for Complex Congenital Heart Disease.

Chylothorax is a critical complication after surgery for congenital heart disease, which markedly compromises the postoperative course with increased mortality. As the cardiovascular load additively causes stagnation of the thoracic duct, chylothorax after palliative cardiac surgery can be highly refractory to the therapies. Here we report a case of two patients with refractory chylothorax attributed to hemodynamic load which was successfully treated with minocycline pleurodesis.

Reliability of respiratory-triggered two-dimensional cine k-adaptive-t-autocalibrating reconstruction for Cartesian sampling for the assessment of biventricular volume and function in patients with repaired tetralogy of Fallot.

Objective: To compare left ventricular (LV) and right ventricular (RV) volume, function, and image quality of a respiratory-triggered two-dimensional (2D)-cine k-adaptive-t-autocalibrating reconstruction for Cartesian sampling (2D kat-ARC) with those of the standard reference, namely, breath-hold 2D balanced steady-state free precession (2D SSFP), in patients with repaired tetralogy of Fallot (TOF).

Methods: 30 patients (14 males, mean age 32.2 ± 13.

Transcatheter Coil Embolization of Single Coronary Artery Fistula Using the Occlusion Test.

The case of a patient in whom hemodynamic and electrocardiographic studies using the occlusion test for coronary artery fistulas (CAF) were safely performed prior to catheter embolization is reported. A 1-year-old girl had a separate right coronary artery arising from a left single coronary artery that formed a significant coronary artery fistula to the right ventricle. Coronary steal by the large coronary artery fistula narrowed the left coronary artery.

A refractory hypertensive patient with fibromuscular dysplasia and multicystic dysplastic kidney.

The case of a 16-year-old male patient with left renal artery stenosis due to fibromuscular dysplasia (FMD) and an atrophic kidney due to a right multicystic dysplastic kidney (MCDK) who presented with refractory hypertension is reported. On continuous Doppler imaging, the peak systolic velocity (PSV) at the stenotic site of the left renal artery was 404 cm/s. The FMD formed a "string-of-beads" appearance on computed tomographic angiography (CTA) and renal artery angiography.
