There are various examination methods for cardiovascular diseases. Non-invasive diagnosis and prognostic information acquisition are the current research hotspots of related imaging examinations. Positron emission tomography (PET)/magnetic resonance imaging (MRI) is a new advanced fusion imaging technology that combines the molecular imaging of PET with the soft tissue contrast function of MRI to achieve their complementary advantages. This article briefly introduces several major aspects of cardiac PET/MRI in the diagnosis of cardiovascular disease, including atherosclerosis, ischemic cardiomyopathy, nodular heart disease, and myocardial amyloidosis, in order to promote cardiac PET/MRI to be more widely used in precision medicine in this field.

Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of reoperation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation.

OBJECTIVE:
To investigate the clinical significance of 3-vessel subsequence view in prenatal screening and diagnosis of fetal congenital heart disease.
METHODS:
The 3-vessel subsequence view of 231 fetuses with congenital heart disease was obtained with Sequoia 512, Voluson 730 and E8 color Doppler ultrasonographic diagnostic system.
RESULTS:
Of the 231 consecutive fetuses with congenital heart defects (CHD), 169 (73%) had at least 1 abnormality on the 3-vessel subsequence view. When ventricl septal defects and so on were excluded, the detection rate increased to 91%. Some defects had several abnormalities visualized at the 3-vessel subsequence view.
CONCLUSION
The 3-vessel subsequence view has high detection rate in identifying the presence of CHD.

OBJECTIVESTo determine the relative value of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in exploring the potential embolic source (PES) in heart and aortic arch and to study the clinical significance of aortic arch atherosclerosis (AAA).
METHODSForty-nine patients with cerebral embolism were included in this study. TEE and TTE were used to evaluate the potential source of emboli in aortic arch, heart and duplex in the carotid artery. An atherosclerotic lesion of the aortic arch was defined as normal, mild plaque, moderate plaque, and protruding plaque or mobile plaque.
RESULTSOf the 49 patients, 31 (63%) patients showed evidence of AAA: 7 (14.1%) patients were mild, 9 (18.4%) were moderate and 15 (30.6%) were severe. In those 15 patients, 11 had neither severe ICAA nor heart disease. Thirty-three patients had internal carotid arterial atherosclerosis (ICAA). The potential sources of embolization of heart and aortic arch is 48.98% by TEE, but only 18.4% by TTE; 9 patients had heart disease. Age and ICAA were significantly correlated with AAA.
CONCLUSIONAt present, TEE is a better method for exploring atherosclerotic lesions in the thoracic aorta. AAA is an important potential source of cerebral embolic stroke.

BACKGROUNDAccurate evaluation of coronary artery, aortic valve annulus diameter (AVAD), and cardiac function in patients with aortic valve disease is of great significance for surgical strategy. In this study, we explored the preoperative evaluation of low-dose sequence (MinDose sequence) scan of dual-source CT (DSCT) for those patients.
METHODSForty patients suspected for aortic valve disease (the experimental group) underwent MinDose sequence of DSCT to observe coronary artery, AVAD, and left ventricular ejection fraction (LVEF). Another 33 subjects suspected for coronary artery disease (the control group) underwent conventional retrospective electrocardiographically-gated sequence of DSCT. Two-dimensional transthoracic echocardiography (2D-TTE) and four-dimensional transthoracic echocardiography (4D-TTE) were applied in the experimental group to measure AVAD and LVEF and compared with MinDose-DSCT.
RESULTSThere was a strong correlation between LVEFs measured by 2D-TTE and MinDose-DSCT (r = 0.87, P < 0.01), as well as between 4D-TTE and MinDose-DSCT (r = 0.90, P < 0.01). AVAD measured by MinDose-DSCT was in good agreement with corresponding measurements by 2D-TTE (r = 0.90, P < 0.01). The effective dose in the experimental group was 63.54% lower than that in the control group.
CONCLUSIONSMinDose sequence of DSCT with a low radiation dose serving as a one-stop preoperative evaluation makes effective assessment of the coronary artery, AVAD, and LVEF for patients with aortic valve disease.
