CLINICAL INTRODUCTION: A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0...

A 45-year-old man without previous comorbidity presented to us with acute onset right-sided flank pain for last 14 hours. His general physical and systemic examination was unremarkable, and there were no clinical signs of peritonitis. The ultrasonography did not reveal any evidence of nephrolithiasis or hydronephrosis. His contrast-enhanced CT scan revealed hypoattenuated areas of right kidney and evidence of right renal artery thrombosis. He was immediately shifted to cardiac catheterisation lab, and his renal angiography showed thrombotic occlusion of right renal artery...

This case report describes a patient who experienced a recurrent ischemic stroke within 24 h. Dual-energy computed tomography (DECT) angiography on admission showed 2 intracardiac thrombi, 1 in the left ventricle and 1 in the left atrial appendage. Following the second ischemic event, repeated DECT angiography showed that the ventricular thrombus had considerably diminished, suggesting that the recurrent brain infarction was caused by cardioembolism. This case emphasizes (1) the potential benefit of cardiac evaluation through CT angiography in the acute stroke setting, and (2) the use of DECT angiography for the detection of thrombus and the differentiation between thrombus, the myocardial wall, and a slow flow of contrast...

Regional cerebral oximetry using near-infrared spectroscopy devices is commonly used for detecting cerebral ischemia during cardiopulmonary bypass, and aim to avoid poor cerebral perfusion which may result in perioperative neurological impairment. Today, several devices that can detect cerebral ischemia are commercially available. Although these devices operate on the same measurement principles, their algorithms for detecting and calculating cerebral ischemia are different and no criteria for directly comparing values measured by such different devices exist...

BACKGROUND: The applicability of ultra-low-dose computed tomography (CT) for attenuation correction (AC) of single-photon-emission computed tomography myocardial perfusion imaging (SPECT-MPI) remains elusive. METHODS AND RESULTS: One-hundred patients underwent one-day 99m Tc-tetrofosmin stress-rest MPI and non-contrast enhanced cardiac CT with 120, 80, and 70 kilovolt peak (kVp) tube voltage and tube current of 200 milliamperes for creation of AC maps. Normalized percent myocardial uptake from SPECT-MPI using 80 kVp scans for AC showed excellent correlation vs AC from 120 kVp scans for stress [intraclass correlation (ICC) = 0...

We present the case of a 35-year-old woman with metastatic neuroendocrine tumor undergoing treatment with long-acting octreotide and Lu-DOTATATE therapy. We present features of carcinoid heart disease on Ga-DOTANOC PET/CT, which revealed dilated right atrium, pericardial effusion, ascites, and congestive hepatopathy apart from the metastatic lesions in the liver. The scan cardiac findings were confirmed by echocardiography. This highlights the significance of identifying such patients early because additional management is required for carcinoid heart disease per se and a cautious approach is needed in administering amino acid infusion during PRRT that can result in fluid overload...

The fusion of 3D anatomical models derived from high-fidelity pre-interventional computed tomography angiography (CTA), and x-ray (XR) fluoroscopy to facilitate anatomical guidance is of huge interest for complex cardiac interventions like TAVI procedures with cerebral protection. Co-registration of CTA and XR has been introduced either based on additional intraoperative non-/contrast-enhanced cone-beam computed tomography (CBCT) or two separate aortograms. With the related increase of radiation exposure and/or contrast agent (CA) dose, a potential additional risk for the patient is introduced...

Aortopulmonary window (APW) is rare a congenital heart disease accounting for 0.1%-0.2% of all congenital heart defects. The 35% of the APW has been associated with wide variety of other structural heart diseases such as ventricular septal defect, persistent ductus arteriosus, arch anomalies and coronary artery anomalies. To the best of our knowledge, only six cases of APW with pulmonary atresia with ventricular septal defect has been described in the literature. It resembles the type 1 truncus arteriosus, and differentiation from this condition is important prior to surgical correction...

A 63-year-old man with cirrhosis, hepatocellular carcinoma, and coagulopathy was diagnosed with a sinus venosus atrial septal defect (ASD) and partial anomalous pulmonary venous return (PAPVR) of the right upper pulmonary vein (RUPV). Transcatheter repair by positioning a stent graft in the superior vena cava was planned. Based on three-dimensional (3D) reconstruction of gated cardiac CTA, a 28 mm × 7 cm Endurant II® aortic extension stent graft (Medtronic, MN) was chosen. A 3D model printed from the CTA was used to simulate device deployment, demonstrating successful exclusion of the sinus venosus ASD with return of the RUPV to the left atrium (LA)...

A 77 year old male underwent elective bioprosthetic aortic valve replacement (23mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnoea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak / mean gradients 49 / 22 mmHg respectively)...
