    Evaluation of Myocardial Perfusion by Computed Tomography - Principles, Technical Background and Recommendations
    (2019) MAGALHAES, Tiago Augusto; CURY, Roberto Caldeira; CERCI, Rodrigo Julio; PARGA FILHO, Jose Rodrigues; GOTTLIEB, Ilan; NACIF, Marcelo Souto; PINTO, Ibraim Masciarelli; ROCHITTE, Carlos Eduardo; VILAS-BOAS, Fabio; SCHVARTZMAN, Paulo R.
    Coronary computed tomography angiography (CCTA) has gained a prominent role in the evaluation of coronary artery disease. However, its anatomical nature does not allow the evaluation of the functional repercussion of coronary obstructions. It has been made possible to evaluate Myocardial computed tomography perfusion (Myocardial CTP) recently, based on myocardial contrast changes related to coronary stenoses. Several studies have validated this technique against the anatomical reference method (cardiac catheterization) and other functional methods, including myocardial perfusion scintigraphy and fractional flow reserve. The Myocardial CTP is performed in conjunction with the CCTA, a combined analysis of anatomy and function. The stress phase (with assessment of myocardial perfusion) can be performed before or after the resting phase (assessment of resting perfusion and coronary arteries), and different acquisition parameters are proposed according to the protocol and type of equipment used. Stressors used are based on coronary vasodilation (e.g. dipyridamole, adenosine). Image interpretation, similar to other perfusion assessment methods, is based on the identification and quantification of myocardial perfusion defects. The integration of both perfusion and anatomical findings is fundamental for the examination interpretation algorithm, allowing to define if the stenoses identified are hemodynamically significant and may be related to myocardial ischemia.

    Coronary Artery Stenoses: Accuracy of 64-Detector Row CT Angiography in Segments with Mild, Moderate, or Severe Calcification-A Subanalysis of the CORE-64 Trial
    (2011) VAVERE, Andrea L.; ARBAB-ZADEH, Armin; ROCHITTE, Carlos E.; DEWEY, Marc; NIINUMA, Hiroyuki; GOTTLIEB, Ilan; CLOUSE, Melvin E.; BUSH, David E.; HOE, John W. M.; ROOS, Albert de; COX, Christopher; LIMA, Joao A. C.; MILLER, Julie M.
    Purpose: To evaluate the influence of cross-sectional arc calcification on the diagnostic accuracy of computed tomography (CT) angiography compared with conventional coronary angiography for the detection of obstructive coronary artery disease (CAD). Materials and Methods: Institutional Review Board approval and written informed consent were obtained from all centers and participants for this HIPAA-compliant study. Overall, 4511 segments from 371 symptomatic patients (279 men, 92 women; median age, 61 years [interquartile range, 53-67 years]) with clinical suspicion of CAD from the CORE-64 multi-center study were included in the analysis. Two independent blinded observers evaluated the percentage of diameter stenosis and the circumferential extent of calcium (arc calcium). The accuracy of quantitative multidetector CT angiography to depict substantial (>50%) stenoses was assessed by using quantitative coronary angiography (QCA). Cross-sectional arc calcium was rated on a segment level as follows: noncalcified or mild (<90 degrees), moderate (90 degrees-180 degrees), or severe (>180 degrees) calcification. Univariable and multivariable logistic regression, receiver operation characteristic curve, and clustering methods were used for statistical analyses. Results: A total of 1099 segments had mild calcification, 503 had moderate calcification, 338 had severe calcification, and 2571 segments were noncalcified. Calcified segments were highly associated (P < .001) with disagreement between CTA and QCA in multivariable analysis after controlling for sex, age, heart rate, and image quality. The prevalence of CAD was 5.4% in noncalcified segments, 15.0% in mildly calcified segments, 27.0% in moderately calcified segments, and 43.0% in severely calcified segments. A significant difference was found in area under the receiver operating characteristic curves (noncalcified: 0.86, mildly calcified: 0.85, moderately calcified: 0.82, severely calcified: 0.81; P < .05). Conclusion: In a symptomatic patient population, segment-based coronary artery calcification significantly decreased agreement between multidetector CT angiography and QCA to detect a coronary stenosis of at least 50%.

    Clinical Outcomes After Evaluation of Stable Chest Pain by Coronary Computed Tomographic Angiography Versus Usual Care: A Meta-Analysis
    (2016) BITTENCOURT, Marcio Sommer; HULTEN, Edward A.; MURTHY, Venkatesh L.; CHEEZUM, Michael; ROCHITTE, Carlos E.; CARLI, Marcelo F. Di; BLANKSTEIN, Ron
    Background Limited data exist on how noninvasive testing options compare for evaluating patients with suspected stable coronary artery disease. In this study, we have performed a meta-analysis of randomized controlled trials comparing the use of coronary computed tomographic angiography (CTA) with usual care. Methods and Results We systematically searched databases for randomized clinical trials comparing coronary CTA with usual care for the evaluation of stable chest pain with follow-up for cardiovascular outcomes. The primary outcomes were myocardial infarction and all-cause mortality. We identified 4 randomized clinical trials, including a total of 7403 patients undergoing coronary CTA and 7414 patients undergoing usual care with various functional testing approaches. When compared with usual care, the use of coronary CTA was associated with a significant reduction in the annual rate of myocardial infarction (rate ratio, 0.69; 95% confidence interval, 0.49-0.98; P=0.038), but no difference was found in all-cause mortality. There was a trend toward more invasive coronary angiographies among patients undergoing coronary CTA (odds ratio, 1.33; 95% confidence interval, 0.95-1.84; P=0.09) and higher use of coronary revascularizations (odds ratio, 1.77; 95% confidence interval, 1.14-2.75). Significant heterogeneity for invasive coronary angiography and revascularization was noted, which was attributable to the Scottish Computed Tomography of the HEART (SCOT-HEART) study. We found no difference in the rate of admission for cardiac chest pain (rate ratio, 1.21; 95% confidence interval, 0.95-1.54). Conclusions In comparison to usual care, an initial investigation of suspected stable coronary artery disease using coronary CTA resulted in a significant reduction in myocardial infarction, an increased incidence of coronary revascularization, and no effect in all-cause mortality. Future studies should further define whether the potential reduction in myocardial infarction identified justifies the increased resource utilization associated with coronary CTA.

    (2023) TESSARI, Fernanda Castiglioni; LOPES, Maria Antonieta Albanez A. de M.; CAMPOS, Carlos M. M.; ROSA, Vitor Emer Egypto; SAMPAIO, Roney Orismar; SOARES, Frederico Jose Mendes Mendonca; LOPES, Rener Romulo Souza; NAZZETTA, Daniella Cian; JR, Fabio Sandoli de Brito; RIBEIRO, Henrique Barbosa; VIEIRA, Marcelo L.

    IntroductionClassical low-flow, low-gradient aortic stenosis (LFLG-AS) is an advanced stage of aortic stenosis, which has a poor prognosis with medical treatment and a high operative mortality after surgical aortic valve replacement (SAVR). There is currently a paucity of information regarding the current prognosis of classical LFLG-AS patients undergoing SAVR and the lack of a reliable risk assessment tool for this particular subset of AS patients. The present study aims to assess mortality predictors in a population of classical LFLG-AS patients undergoing SAVR.MethodsThis is a prospective study including 41 consecutive classical LFLG-AS patients (aortic valve area & LE;1.0 cm(2), mean transaortic gradient <40 mmHg, left ventricular ejection fraction <50%). All patients underwent dobutamine stress echocardiography (DSE), 3D echocardiography, and T1 mapping cardiac magnetic resonance (CMR). Patients with pseudo-severe aortic stenosis were excluded. Patients were divided into groups according to the median value of the mean transaortic gradient (& LE;25 and >25 mmHg). All-cause, intraprocedural, 30-day, and 1-year mortality rates were evaluated.ResultsAll of the patients had degenerative aortic stenosis, with a median age of 66 (60-73) years; most of the patients were men (83%). The median EuroSCORE II was 2.19% (1.5%-4.78%), and the median STS was 2.19% (1.6%-3.99%). On DSE, 73.2% had flow reserve (FR), i.e., an increase in stroke volume & GE;20% during DSE, with no significant differences between groups. On CMR, late gadolinium enhancement mass was lower in the group with mean transaortic gradient >25 mmHg [2.0 (0.0-8.9) g vs. 8.5 (2.3-15.0) g; p = 0.034), and myocardium extracellular volume (ECV) and indexed ECV were similar between groups. The 30-day and 1-year mortality rates were 14.6% and 43.8%, respectively. The median follow-up was 4.1 (0.3-5.1) years. By multivariate analysis adjusted for FR, only the mean transaortic gradient was an independent predictor of mortality (hazard ratio: 0.923, 95% confidence interval: 0.864-0.986, p = 0.019). A mean transaortic gradient & LE;25 mmHg was associated with higher all-cause mortality rates (log-rank p = 0.038), while there was no difference in mortality regarding FR status (log-rank p = 0.114).ConclusionsIn patients with classical LFLG-AS undergoing SAVR, the mean transaortic gradient was the only independent mortality predictor in patients with LFLG-AS, especially if & LE;25 mmHg. The absence of left ventricular FR had no prognostic impact on long-term outcomes.

    (2023) MELO, Rodrigo J. L.; ASSUNCAO, Antonildes N.; MORAIS, Thamara C.; NOMURA, Cesar H.; SCANAVACCA, Mauricio I.; MARTINELLI-FILHO, Martino; RAMIRES, Felix J. A.; FERNANDES, Fabio; IANNI, Barbara M.; MADY, Charles; ROCHITTE, Carlos E.
    Purpose: To evaluate myocardial T1 mapping and extracellular volume (ECV) parameters in different stages of Chagas cardiomyopathy and determine whether they are predictive of disease severity and prognosis.Materials and Methods: Prospectively enrolled participants (July 2013 to September 2016) underwent cine and late gadolinium enhancement (LGE) cardiac MRI and T1 mapping with a precontrast (native) or postcontrast modified Look-Locker sequence. The native T1 and ECV values were measured among subgroups that were based on disease severity (indeterminate, Chagas cardiomyopathy with preserved ejection fraction [CCpEF], Chagas cardiomyopathy with midrange ejection fraction [CCmrEF], and Chagas cardiomyopathy with reduced ejection fraction [CCrEF]). Cox proportional hazards regression and the Akaike information criterion were used to determine predictors of major cardiovascular events (cardioverter defibrillator implant, heart transplant, or death).Results: In 107 participants (90 participants with Chagas disease [mean age & PLUSMN; SD, 55 years & PLUSMN; 11; 49 men] and 17 age-and sex matched control participants), the left ventricular (LV) ejection fraction and the extent of focal and diffuse or interstitial fibrosis were correlated with disease severity. Participants with CCmrEF and participants with CCrEF showed significantly higher global native T1 and ECV values than participants in the indeterminate, CCpEF, and control groups (T1: 1072 msec & PLUSMN; 34 and 1073 msec & PLUSMN; 63 vs 1010 msec & PLUSMN; 41, 1005 msec & PLUSMN; 69, and 999 msec & PLUSMN; 46; ECV: 35.5% & PLUSMN; 3.6 and 35.0% & PLUSMN; 5.4 vs 25.3% & PLUSMN; 3.5, 28.2% & PLUSMN; 4.9, and 25.2% & PLUSMN; 2.2; both P < .001). Remote (LGE-negative areas) native T1 and ECV values were also higher (T1: 1056 msec & PLUSMN; 32 and 1071 msec & PLUSMN; 55 vs 1008 msec & PLUSMN; 41, 989 msec & PLUSMN; 96, and 999 msec & PLUSMN; 46; ECV: 30.2% & PLUSMN; 4.7 and 30.8% & PLUSMN; 7.4 vs 25.1% & PLUSMN; 3.5, 25.1% & PLUSMN; 3.7, and 25.0% & PLUSMN; 2.2; both P < .001). Abnormal remote ECV values (>30%) occurred in 12% of participants in the indeterminate group, which increased with disease severity. Nineteen combined outcomes were observed (median follow-up time: 43 months), and a remote native T1 value greater than 1100 msec was independently predictive of combined outcomes (hazard ratio, 12 [95% CI: 4.1, 34.2]; P < .001).Conclusion: Myocardial native T1 and ECV values were correlated with Chagas disease severity and may serve as markers of myocardial involvement in Chagas cardiomyopathy that precede LGE and LV dysfunction.

    Quantification of aortic stenosis diagnostic parameters: comparison of fast 3 direction and 1 direction phase contrast CMR and transthoracic echocardiography
    (2017) SILVEIRA, Juliana Serafim da; SMYKE, Matthew; RICH, Adam V.; LIU, Yingmin; JIN, Ning; SCANDLING, Debbie; DICKERSON, Jennifer A.; ROCHITTE, Carlos E.; RAMAN, Subha V.; POTTER, Lee C.; AHMAD, Rizwan; SIMONETTI, Orlando P.
    Background: Aortic stenosis (AS) is a common valvular disorder, and disease severity is currently assessed by transthoracic echocardiography (TTE). However, TTE results can be inconsistent in some patients, thus other diagnostic modalities such as cardiovascular magnetic resonance (CMR) are demanded. While traditional unidirectional phase-contrast CMR (1Dir PC-CMR) underestimates velocity if the imaging plane is misaligned to the flow direction, multi-directional acquisitions are expected to improve velocity measurement accuracy. Nonetheless, clinical use of multidirectional techniques has been hindered by long acquisition times. Our goal was to quantify flow parameters in patients using 1Dir PC-CMR and a faster multi-directional technique (3Dir PC-CMR), and compare to TTE. Methods: Twenty-three patients were prospectively assessed with TTE and CMR. Slices above the aortic valve were acquired for both PC-CMR techniques and cine SSFP images were acquired to quantify left ventricular stroke volume. 3Dir PC-CMR implementation included a variable density sampling pattern with acceleration rate of 8 and a reconstruction method called ReVEAL, to significantly accelerate acquisition. 3Dir PC-CMR reconstruction was performed offline and ReVEAL-based image recovery was performed on the three (x, y, z) encoding pairs. 1Dir PC-CMR was acquired with GRAPPA acceleration rate of 2 and reconstructed online. CMR derived flow parameters and aortic valve area estimates were compared to TTE. Results: ReVEAL based 3Dir PC-CMR derived parameters correlated better with TTE than 1Dir PC-CMR. Correlations ranged from 0.61 to 0.81 between TTE and 1Dir PC-CMR and from 0.61 to 0.87 between TTE and 3Dir-PC-CMR. The correlation coefficients between TTE, 1Dir and 3Dir PC-CMR V(peak)were 0.81 and 0.87, respectively. In comparison to ReVEAL, TTE slightly underestimates peak velocities, which is not surprising as TTE is only sensitive to flow that is parallel to the acoustic beam. Conclusions: By exploiting structure unique to PC-CMR, ReVEAL enables multi-directional flow imaging in clinically feasible acquisition times. Results support the hypothesis that ReVEAL-based 3Dir PC-CMR provides better estimation of hemodynamic parameters in AS patients in comparison to 1Dir PC-CMR. While TTE can accurately measure velocity parallel to the acoustic beam, it is not sensitive to the other directions of flow. Therefore, multi-directional flow imaging, which encodes all three components of the velocity vector, can potentially outperform TTE in patients with eccentric or multiple jets.
