We studied feasibility and accuracy of sequential coronary computed tomography angiography (CTA) and TTDE in detection of haemodynamically significant coronary artery disease (CAD). ..................................................................................................................................................................................... Methods We prospectively enrolled 107 patients with intermediate (30–70%) pre-test likelihood of CAD. All patients under- and results went CTA using a 64-slice scanner. Using TTDE, the ratio of maximal diastolic flow velocity to pre-stenotic flow velocity (M/P ratio) was measured in the coronary segments with stenosis in CTA. In all patients, the results were compared with invasive coronary angiography, including measurement of fractional flow reserve when appropriate. -

St. Kuntz-Hehner1, K. Tiemann1, Th. Schlosser1, H. Omran1, B. Luederitz1, H. Becher2 Increasing interest has been focused on myocardial contrast echocardiography (MCE) since latest ultrasound-specific imaging modalities allow the detection of ultrasound contrast agents within the myocardium after intravenous injection. Due to significant improvements in imaging technology MCE has become a valuable add-on tool for the diagnosis of coronary artery disease. This review summarizes and estimates the clinical value of recent developments in myocardial contrast echocardiography, particularly with regard to the new real-time perfusion imaging, which allows simultaneous assessment of perfusion and wall- motion.

Dual Imaging Stress Echocardiography Versus Computed
Ciampi et al. Cardiovascular Ultrasound (2015) 13:21 DOI 10.1186/s12947-015-0013-8 CARDIOVASCULAR ULTRASOUND RESEARCH Open Access Dual imaging stress echocardiography versus computed tomography coronary angiography for risk stratification of patients with chest pain of unknown origin Quirino Ciampi1,2*, Fausto Rigo3, Elisabetta Grolla3, Eugenio Picano2 and Lauro Cortigiani4 Abstract Background: Dual imaging stress echocardiography, combining the evaluation of wall motion and coronary flow reserve (CFR) on the left anterior descending artery (LAD), and computed tomography coronary angiography (CTCA) are established techniques for assessing prognosis in chest pain patients. In this study we compared the prognostic value of the two methods in a cohort of patients with chest pain having suspected coronary artery disease (CAD). Methods: A total of 131 patients (76 men; age 68 ± 9 years) with chest pain of unknown origin underwent dipyridamole (up to 0.84 mg/kg over 6 min) stress echo with CFR assessment of LAD by Doppler and CTCA. A CFR ≤ 1.9 was considered abnormal, while > 50% lumen diameter reduction was the criterion for significant CAD at CTCA. Results: Of 131 patients, 34 (26%) had ischemia at stress echo (new wall motion abnormalities), and 56 (43%) had reduced CFR on LAD. Significant coronary stenosis at CTCA was found in 69 (53%) patients. Forty-six patients (84%) with abnormal CFR on LAD showed significant CAD at CTCA (p < 0.001). Calcium score was higher in patients with reduced than in those with normal CFR (265 ± 404 vs 131 ± 336, p = 0.04). During a median follow-up of 7 months (1st to 3rd quartile: 5–13 months), there were 45 major cardiac events (4 deaths, 11 nonfatal myocardial infarctions, and 30 late [≥6 months] coronary revascularizations). -
A Presentation of Congenital Cor-Triatriatum

In literature, majority case reports on the condition focused on its late presentation in adulthood. It can be easily corrected by surgical intervention to avoid pulmonary congestion and subsequent pulmonary hypertension. We report a rare case of cor-triatriatum with severe pulmonary hypertension in a 7-week-old baby who presented with persistent tachypnoea. Keywords: Received: 1 July 2019; Accepted revised manuscript: 2 Cor-triatriatum; Cardiac failure; Tachypnoea April 2020 Published online: 18 April 2020 Introduction Following completion of antibiotic treatment, Cor-triatriatum is a rare cardiac malformation and baby X maintained his respiratory rate at 65 may present with variation in clinical breaths/minute with saturation of 97% in FiO2 presentation. Its incidence is estimated at about 0.35. There was no adventitious breath sound on 0.1% of all congenital heart disease. In this auscultation, apex beat was palpable at the anomaly, the atrium is divided by a fibromuscular fourth intercostal space midclavicular line with membrane into two distinct chambers: a the presence of loud second heart sound at the posterior- superior chamber which receives the pulmonary area. His liver edge was palpable 1 cm four pulmonary veins and an anterior-inferior below the right costal margin. His chest chamber (true left atrium) which connected to radiograph showed normal cardiac contour with the ventricle via atrioventricular valves. -
