				<title>Abstract</title>
				<p>Echocardiographic assessment of mitral regurgitation (MR) is multiparametric and often challenging. The artifact known as splay has been described as an additional tool for estimating the severity of regurgitation. The term refers to a side-lobe artifact that forms a horizontal arc on color Doppler imaging. This same phenomenon can also be observed in other valvular heart diseases, such as aortic regurgitation. In 2020, Wiener et al. reported that splay was present in 81% of cases of significant MR, reaching 93% in eccentric jets, whereas the prevalence was only 16% in mild MR. Verbeke et al. associated the artifact with larger regurgitant volumes. A splay width greater than 29 mm was identified as an independent predictor of adverse cardiovascular outcomes. Although its presence alone does not denote severe MR, splay acts as a red flag, suggesting that regurgitation may be greater than it appears and indicating the need for careful reassessment of the transthoracic echocardiogram or, possibly, complementary transesophageal echocardiography. Further evidence and systematic evaluations are needed to investigate the best strategy for incorporating these data into the multiparametric approach to MR.</p>

			<title>The challenge of grading mitral regurgitation severity</title>
			<p>Echocardiographic assessment of mitral regurgitation (MR) is multiparametric and often challenging. Especially in the presence of multiple, eccentric, non-homogeneous jets throughout the cardiac cycle or non-circular regurgitant orifices, it is paramount to combine qualitative and quantitative data that can guide the grading of valvular regurgitation.<sup><xref ref-type="bibr" rid="B1">1</xref>,<xref ref-type="bibr" rid="B2">2</xref></sup> In this context, an artifact has been described as an additional finding in the assessment of MR.</p>
		</sec>
		<sec>
			<title>Splay: a valuable artifact</title>
			<p>The term splay refers to a side-lobe artifact that appears as a horizontal arc on color Doppler imaging, dispersing signal and usually observed along the atrial surface of the valve, extending beyond anatomical boundaries<sup><xref ref-type="bibr" rid="B3">3</xref></sup> (<xref ref-type="fig" rid="f1">Figure 1</xref>).</p>
			<fig id="f1">
				<label>Figure 1</label>
				<caption>
					<title>Splay in MR. On the left, transthoracic echocardiography in the apical 3-chamber view shows evidence of splay on color Doppler at the level of the mitral annulus. On the right, transesophageal echocardiography reveals significant MR with a medially directed eccentric jet.</title>
				</caption>
				<graphic xlink:href="2675-312X-abcic-39-02-e20260024-gf01.tif"/>
			</fig>
			<p>Ultrasound transducers emit energy not only in the main direction (central axis of the beam), but also in lateral directions, forming secondary lobes of lower intensity. When these side lobes encounter highly reflective structures, such as cardiac walls or valves, they may generate echoes that are incorrectly mapped by the imaging system, as if they originated from the main axis, resulting in artifacts on echocardiographic images.<sup><xref ref-type="bibr" rid="B4">4</xref></sup></p>
			<p>Considering the mechanism that gives rise to this artifact, splay can be documented in other valvular regurgitations, for example, aortic regurgitation (<xref ref-type="fig" rid="f2">Figure 2</xref>).</p>
			<fig id="f2">

In the upper images, transthoracic echocardiography in the parasternal long-axis (A) and short-axis (B) views shows evidence of splay, extending beyond anatomical boundaries. In the lower images (C and D), transesophageal echocardiogram reveals an eccentric aortic regurgitant jet originating from the commissural region.</title>

			<title>Evidence of diagnostic and prognostic value</title>
			<p>In 2020, Wiener et al.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> described this artifact as a clue for detecting significant MR. In an analysis of 200 cases of MR documented by transthoracic echocardiography, half with significant regurgitation and half with mild regurgitation, the prevalence of splay was 81% and 16%, respectively. In eccentric jets, the prevalence reached 93% of cases. This sign was observed in proto-, meso-, tele-, and holosystolic jets; on the atrial and ventricular surface of the mitral annulus; in preserved and reduced left ventricular ejection fraction; in different etiologies (prolapse, rheumatic disease, mitral annulus calcification, functional); and using different commercially available echocardiogram brands. It has most frequently been documented in apical views, but it has also been observed in parasternal long- and short-axis views. The origin of the signal appears to be related to blood flow rate per unit area. With higher gain, lower ultrasound frequency, and lower Nyquist limit, higher prevalence and greater extent of splay are observed. In their study, harmonic imaging had little effect on splay.</p>
			<p>In a single-center registry by Verbeke et al.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> in Ghent, Belgium, a 27% prevalence of color Doppler splay was reported in 469 patients, correlating with greater effective regurgitant orifice area, regurgitant volume, and vena contracta width. They used a Vivid E9 echocardiographic system, GE Healthcare, equipped with an M5Sc-D transducer for all examinations. For color Doppler assessment, the following standardized parameters were applied for all patients: transmission frequency of 2.2 MHz, velocity scale of 3.5 kHz (aliasing velocity of 63 cm/s), and gain adjusted to −5 dB. Splay was more prevalent and showed greater width in patients with significant MR. In their cohort, splay width greater than 29 mm was an independent predictor of cardiovascular outcomes, with additional prognostic value.</p>
		</sec>
		<sec sec-type="conclusions">
			<title>Final considerations</title>
			<p>This is a relatively recent description of an echocardiographic sign that requires further evidence and studies to guide its systematic integration into echocardiographic practice. Although it does not necessarily indicate significant MR and is not indispensable for defining this severity, splay represents a potential tool signaling the possibility that regurgitation is more severe than appears. This red flag prompts careful reassessment of the transthoracic echocardiogram and, when appropriate, complementary transesophageal echocardiography when other findings lead us to suspect significant MR (<xref ref-type="fig" rid="f3">Central Illustration</xref>).</p>
			<p>In the words of Bertrand et al.,<sup><xref ref-type="bibr" rid="B6">6</xref></sup> splay is &quot;the artifact that tells the truth,&quot; by signaling the possibility of significant MR.</p>

				<title>Resumo</title>
				<p>A avaliação ecocardiográfica da insuficiência mitral (IM) é multiparamétrica e frequentemente desafiadora. O artefato conhecido como <italic>splay</italic> tem sido descrito como uma ferramenta adicional para estimar a gravidade da regurgitação. O termo significa &quot;espalhar&quot; e refere-se a um artefato de lobo lateral que forma um arco horizontal no Doppler colorido. Esse mesmo fenômeno também pode ser observado em outras valvopatias, como a insuficiência aórtica. Em 2020, Wiener et al. descreveram que o <italic>splay</italic> esteve presente em 81% dos casos de IM importante, chegando a 93% em jatos excêntricos, com prevalência de apenas 16% na IM discreta. Verbeke et al. associaram o artefato a maiores volumes regurgitantes. Uma largura de <italic>splay</italic> superior a 29 mm foi identificada como preditor independente de desfechos cardiovasculares adversos. Embora sua presença isoladamente não denote IM grave, o <italic>splay</italic> atua como um sinal de alerta (<italic>red flag</italic>). Ele sugere que a regurgitação pode ser maior do que a aparente, indicando a necessidade de uma revisão cuidadosa do exame transtorácico ou, eventualmente, complementação com ecocardiograma transesofágico. Maiores evidências e avaliações sistematizadas são necessárias para estudar a melhor estratégia de incorporação desse dado na abordagem multiparamétrica da IM.</p>

					<title>O desafio da graduação da insuficiência mitral</title>
					<p>A avaliação ecocardiográfica da insuficiência mitral (IM) é multiparamétrica e frequentemente desafiadora. Principalmente na presença de jatos múltiplos, excêntricos, não homogêneos ao longo do ciclo cardíaco ou com orifícios regurgitantes não circulares, o uso combinado de dados qualitativos e quantitativos que possam direcionar a graduação da regurgitação valvar é primordial.<sup><xref ref-type="bibr" rid="B1">1</xref>,<xref ref-type="bibr" rid="B2">2</xref></sup> Nesse contexto, um artefato tem sido descrito como um dado adicional na avaliação da IM.</p>

					<title><italic>Splay</italic>: um artefato valioso</title>
					<p>O termo <italic>splay</italic> (&quot;espalhar&quot;) é um artefato de lobo lateral e remete a um arco horizontal formado pelo Doppler colorido, que se dispersa, sendo usualmente observado ao nível do plano valvar atrial, sem respeito aos limites anatômicos<sup><xref ref-type="bibr" rid="B3">3</xref></sup> (<xref ref-type="fig" rid="f4">Figura 1</xref>).</p>

					<p>O transdutor de ultrassom não emite energia apenas na direção principal (eixo central do feixe), mas também em direções laterais, formando lobos secundários de menor intensidade. Quando esses lobos laterais encontram estruturas altamente refletoras, como paredes cardíacas ou válvulas, podem gerar ecos que são erroneamente posicionados pelo sistema de imagem como se fossem oriundos do eixo principal, resultando em artefatos visuais na imagem ecocardiográfica.<sup><xref ref-type="bibr" rid="B4">4</xref></sup></p>
					<p>Considerado o mecanismo que origina esse artefato, faz-se possível documentar o <italic>splay</italic> em outras regurgitações valvares, por exemplo, na insuficiência aórtica (<xref ref-type="fig" rid="f5">Figura 2</xref>).</p>

					<title>Evidências de valor diagnóstico e prognóstico</title>
					<p>Em 2020, Wiener et al.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> descreveram esse artefato como uma pista para a detecção de IM significativa. Em análise de 200 casos de IM documentados ao ecocardiograma transtorácico, metade com regurgitação importante e metade com regurgitação discreta, a prevalência do <italic>splay</italic> foi de 81% e 16%, respectivamente. Sobretudo nos jatos excêntricos, a prevalência atingiu 93% dos casos. Tal sinal foi observado em jatos proto, meso, tele ou holossistólicos, em face atrial ou ventricular do anel mitral, na fração de ejeção ventricular esquerda preservada ou reduzida, nas diferentes etiologias (prolapso, doença reumática, calcificação do anel mitral, funcional) e em diferentes marcas de ecocardiograma comercialmente disponíveis. Documentou-se mais frequentemente nas janelas apicais, mas foi observado também na janela paraesternal em eixo longo e eixo curto. A origem do sinal parece estar relacionada à taxa de fluxo sanguíneo por unidade de área. Na presença de maior ganho, menor frequência ultrassonográfica e menor limite de Nyquist, observam-se maior prevalência e extensão desse artefato. Nesse estudo, a imagem harmônica teve pouco efeito no <italic>splay</italic>.</p>
					<p>Em registro unicêntrico de Verbeke et al.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> em Ghent, Bélgica, documentou-se prevalência de 27% do <italic>splay</italic> no Doppler colorido em 469 pacientes, correlacionando-se com valores mais elevados de orifício regurgitante efetivo, volume regurgitante e <italic>vena contracta.</italic> Foi utilizado um sistema ecocardiográfico Vivid E9, GE Healthcare, equipado com transdutor M5Sc-D para todos os exames. Para a avaliação com Doppler colorido, foram aplicados parâmetros padronizados em todos os pacientes: frequência de transmissão de 2,2 MHz, escala de velocidade de 3,5 kHz (velocidade de <italic>aliasing</italic> de 63 cm/s) e ganho ajustado para −5 dB. O <italic>splay</italic> foi mais prevalente e apresentou maior largura nos pacientes com IM importante. Nessa coorte, a largura do <italic>splay</italic> acima de 29 mm foi preditora independente de desfechos cardiovasculares e apresentou valor prognóstico adicional.</p>

				<title>Considerações finais</title>
				<p>Trata-se de uma descrição relativamente recente de um sinal ecocardiográfico que demanda evidências adicionais e estudos que nos indiquem como integrá-lo de forma sistemática na prática ecocardiográfica. Apesar de não indicar necessariamente uma IM importante, nem ser indispensável para definir tal gravidade, o <italic>splay</italic> se apresenta como uma ferramenta potencial que sinaliza a possibilidade de uma regurgitação maior que a aparente. Esse sinal de alerta (<italic>red flag</italic>) nos direciona para uma cuidadosa revisão do exame transtorácico e, eventualmente, para uma complementação transesofágica na presença de outros dados que nos levem à suspeita de uma IM significativa (<xref ref-type="fig" rid="f6">Figura Central</xref>).</p>
				<p>Como referido por Bertrand et al.,<sup><xref ref-type="bibr" rid="B6">6</xref></sup> o <italic>splay</italic> é o artefato que pode nos mostrar a realidade, ao sinalizar a possibilidade de uma IM significativa.</p>
