“…The patient in our case report underwent a detailed cardiological evaluation with electrocardiogram, 2D echocardiography, and cardiac CT dynamic study. Cardiac CT is a noninvasive technique that offers several approaches to establish the hemodynamic severity of coronary artery obstructions, demonstrates a good correlation with directly measured coronary flow and fractional flow reserve [20], and provides incremental diagnostic value over coronary CT angiography alone for the identification of hemodynamically significant coronary artery disease [21].…”

Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease. Its surgical correction requires ventricular septal defect (VSD) closure and right ventricular outflow tract obstruction (RVOTO) relief, with transannular patch enlargement (TAPE) of the pulmonary valve. The first successful repair of TOF was reported in 1954 and consisted of closure of the VSD through a large right ventriculotomy, and RVOTO relief with TAPE of the pulmonary valve. To predict the intra-operative requirements and post-operative course of patients with this condition, various evaluation indices are available that can provide a good indication of patient prognosis. In this case report, we describe a novel pulmonary vein index (PVI) indicator that offers prognostic indications for pediatric cardiac patients who have undergone surgical correction of TOF.

“…Alternatively, CT-MBF can be assessed by manually placed regions of interest, while MBF also varies between individuals for various clinical conditions. Reported MBF cut-off values vary substantially from 0.75 to 1.64 mL/g/min between studies [29,30]. Physicians should pay attention to the perfusion territory by targeted vessels or branches in the interpretation of myocardial ischemia with the two techniques.…”

Computed tomography (CT) has become one of the essential medical tools in the diagnosis of coronary artery disease (CAD).Cardiac CT has been used for anatomical evaluation of stenosis, plaques, and calcification. CT angiography (CTA) is a noninvasive assessment for the presence of coronary stenosis, and is used clinically as a standard modality to diagnose ischemic heart disease (IHD) [1][2][3]. Although anatomical information on the coronary arteries is indispensable for the diagnosis of CAD, an evaluation of myocardial ischemia provides more important prognostic information beyond the severity of organic coronary stenosis. The evolution of myocardial perfusion imaging has increased the value of noninvasive assessment of myocardial ischemia [4][5][6][7]. As an

“…MBF is the ratio of the convoluted maximal slope of the “time-attenuation curve” of the myocardium and arterial input function ( 116 ). The normal range of MBF varies among studies: from 75 to 164 ml/min/100 ml ( 117 ). CFR is the ratio of MBF during hyperemia to MBF at rest ( 118 ).…”

Ischemia with non-obstructive coronary arteries (INOCA) has gained increasing attention due to its high prevalence, atypical clinical presentations, difficult diagnostic procedures, and poor prognosis. There are two endotypes of INOCA—one is coronary microvascular dysfunction and the other is vasospastic angina. Diagnosis of INOCA lies in evaluating coronary flow reserve, microcirculatory resistance, and vasoreactivity, which is usually obtained via invasive coronary interventional techniques. Non-invasive diagnostic approaches such as echocardiography, single-photon emission computed tomography, cardiac positron emission tomography, and cardiac magnetic resonance imaging are also valuable for assessing coronary blood flow. Some new techniques (e.g., continuous thermodilution and angiography-derived quantitative flow reserve) have been investigated to assist the diagnosis of INOCA. In this review, we aimed to discuss the pathophysiologic basis and contemporary and novel diagnostic approaches for INOCA, to construct a better understanding of INOCA evaluation.
