We present the case of a 4-year-old girl with tetralogy of Fallot associated with an incidentally detected isolation of the left brachiocephalic artery, with no communication between it and the pulmonary artery or ductus arteriosus. The case highlights the unusual association and hemodynamic consequences of the condition.

Objective: The present study sought to compare the reliability and radiation dose of coronary artery calcium (CAC) scoring using low tube current (16 mAs), low kilo-voltage peak (100 kVp) and advanced modelled iterative reconstruction (ADMIRE 5) with the standard protocol (80 mAs, 120 kVp, ADMIRE 3).

Material And Methods: A prospective single centre study including 200 consecutive patients with suspected coronary artery disease referred for CT coronary angiography was conducted. All 200 patients underwent CAC scoring using the low current-low kVp protocol as well as standard protocol and were subdivided into a derivation and validation cohorts.

We describe a case of a 30-year-old woman with gradually increasing dyspnoea on exertion where CT angiography revealed a unicuspid unicommissural morphology of the aortic valve. The present report highlights the anatomical and embryological aspects of this rare anatomical variant as well as the associated cardiovascular abnormalities.

Article Synopsis
  • * A retrospective review of 366 patients revealed that 67.5% had isomeric right atrial appendages and 32.5% had isomeric left atrial appendages, with 86.3% showing a congruent thoraco-abdominal arrangement and 13.6% displaying disharmonious patterns.
  • * The findings indicate that disharmony is more common in patients with isomeric right atrial appendages and is primarily observed at the abdominal level, suggesting the need for a detailed

Pentalogy of Cantrell is a rare congenital anomaly involving the anterior diaphragm, pericardium, sternum, peritoneum, and associated intracardiac defects. In this report, we describe a neonate with pentalogy of Cantrell evaluated with multimodality imaging and successfully managed by a multidisciplinary team.

We recently encountered several cases of tetralogy of Fallot with an abnormally oriented S-shaped ascending aorta. In this retrospective study, we sought to clarify morphology of this unusual under-recognized variant. Databases were reviewed to identify all patients with tetralogy of Fallot having an S-shaped ascending aorta.

Introduction: The present study sought to compare the diagnostic accuracy and radiation dose of ECG-gated, ultra-fast, low-dose, high-pitch, spiral (FLASH) mode versus conventional, ECG-gated, sequential coronary artery calcium (CAC) scoring in patients with suspected coronary artery disease (CAD).

Methods: The study included 120 patients who underwent both conventional scanning and FLASH mode scanning and were subdivided into derivation and validation cohorts. In the conventional sequential (step-and-shoot) protocol, prospective ECG-gated, non-contrast acquisition was performed at 70% of R-R interval.

A 2-month-old male with surgically resected sacral chordoma presented with multiple hypopigmented macules showing characteristic patchy, sharply demarcated areas of pigment network on dermoscopy. These dermoscopic findings were suggestive of the ash-leaf macules of tuberous sclerosis over other common hypopigmented macules in neonates. Chordomas presenting in early childhood in the sacral location have been reported as a rare manifestation of tuberous sclerosis complex.
