“…11 Detailed anatomy of the LA pulmonary veins and neighbouring structures can be easily provided using CT imaging and is important for procedural planning and to help minimize the risk of complications. 153,154 The number of pulmonary veins, pattern of branching, ostial morphology and measurements, and more importantly anomalous pulmonary vein variants, accessory pulmonary veins, or anomalous pulmonary venous drainage can be easily identified by CT compared with other modalities such as TOE and ICE. 154 -157 Spontaneous echo contrast was more commonly diagnosed with ICE (P , 0.01).…”

“…160 Furthermore, spatial orientation of the LA and the pulmonary veins to the oesophagus can be easily identified and is beneficial in risk reduction of lethal complications such as atrio-oesophageal fistula caused by high-energy application during ablation procedures. 153,154 Pulmonary vein stenosis is nowadays an infrequent, yet known complication following catheter ablation procedures. 161,162 In patients with symptoms suggestive of pulmonary venous obstruction, serial CT assessment of pulmonary veins allows for detection or exclusion of stenosis.…”

Atrial fibrillation (AF) is the commonest cardiac rhythm disorder. Evaluation of patients with AF requires an electrocardiogram, but imaging techniques should be considered for defining management and driving treatment. The present document is an expert consensus from the European Association of Cardiovascular Imaging (EACVI) and the European Heart Rhythm Association. The clinical value of echocardiography, cardiac magnetic resonance (CMR), computed tomography (CT), and nuclear imaging in AF patients are challenged. Left atrial (LA) volume and strain in echocardiography as well as assessment of LA fibrosis in CMR are discussed. The value of CT, especially in planning interventions, is highlighted. Fourteen consensus statements have been reached. These may serve as a guide for both imagers and electrophysiologists for best selecting the imaging technique and for best interpreting its results in AF patients.

“…Not only can cardiac CT show the anatomy of a normal pericardium, it can also show the area of a lesion three-dimensionally in constrictive pericarditis with calcifications, making it possible to plan treatment such as pericardiectomy (246, 247, 248, 249). Also, cardiac CT allows anatomic evaluation of the pulmonary vein and cardiac veins before procedures are performed to manage arrhythmia (250, 251, 252, 253, 254, 255). By observing anatomical structures before a procedure is performed, it is possible to select patients for whom certain procedures are possible and prevent complications from occurring after surgery.…”

Korean Guidelines for the Appropriate Use of Cardiac CT

et al. 2015

The development of cardiac CT has provided a non-invasive alternative to echocardiography, exercise electrocardiogram, and invasive angiography and cardiac CT continues to develop at an exponential speed even now. The appropriate use of cardiac CT may lead to improvements in the medical performances of physicians and can reduce medical costs which eventually contribute to better public health. However, until now, there has been no guideline regarding the appropriate use of cardiac CT in Korea. We intend to provide guidelines for the appropriate use of cardiac CT in heart diseases based on scientific data. The purpose of this guideline is to assist clinicians and other health professionals in the use of cardiac CT for diagnosis and treatment of heart diseases, especially in patients at high risk or suspected of heart disease.

Objectives Visualizing left atrial anatomy including the pulmonary veins (PVs) is important for planning the procedure of pulmonary vein isolation with ablation in patients with atrial fibrillation (AF). The aims of our study are to investigate the feasibility of the 3D whole-heart bright-blood and black-blood phase-sensitive (BOOST) inversion recovery sequence in patients with AF scheduled for ablation or electro-cardioversion, and to analyze the correlation between image quality and heart rate and rhythm of patients. Methods BOOST was performed for assessing PVs both with T2 preparation pre-pulse (T2prep) and magnetization transfer preparation (MTC) in 45 patients with paroxysmal or permanent AF scheduled for ablation or electro-cardioversion. Image quality analyses were performed by two independent observers. Qualitative assessment was made using the Likert scale; for quantitative analysis, signal to noise ratios (SNR) and contrast to noise ratios (CNR) were calculated for each PV. Heart rate and rhythm were analyzed based on standard 12-lead ECGs. Results All MTC-BOOST acquisitions achieved diagnostic quality in the PVs, while a significant proportion of T2prep-BOOST images were not suitable for assessing PVs. SNR and CNR values of the MTC-BOOST bright-blood images were higher if patients had sinus rhythm. We found a significant or nearly significant negative correlation between heart rate and the SNR and CNR values of MTC-BOOST bright-blood images. Conclusion 3D whole-heart MTC-BOOST bright-blood imaging is suitable for visualizing the PVs in patients with AF, producing diagnostic image quality in 100% of cases. However, image quality was influenced by heart rate and rhythm. Clinical relevance statement The novel 3D whole-heart BOOST CMR sequence needs no contrast administration and is performed during free-breathing; therefore, it is easy to use for a wide range of patients and is suitable for visualizing the PVs in patients with AF. Key Points • The applicability of the novel 3D whole-heart bright-blood and black-blood phase-sensitive sequence to pulmonary vein imaging in clinical practice is unknown. • Magnetization transfer-bright-blood and black-blood phase-sensitive imaging is suitable for visualizing the pulmonary veins in patients with atrial fibrillation with excellent or good image quality. • Bright-blood and black-blood phase-sensitive cardiac magnetic resonance sequence is easy to use for a wide range of patients as it needs no contrast administration and is performed during free-breathing.
