What is the clinical evidence from this study?

Study design: Case Report. Population: Anomalous drainage of the right superior vena cava into the left atrium (n=1). Intervention: Peripheral contrast echocardiography. Primary outcome: Detection of anomalous drainage via contrast echoes.

What does this research mean for the field?

Peripheral contrast echocardiography can identify anomalous drainage of the right superior vena cava into the left atrium through the direct appearance of contrast echoes in the left heart chambers without right heart opacification. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Evaluate the source of systemic desaturation and unexplained cyanosis in an infant presenting with an apparently structurally normal heart.

Key result

Peripheral contrast echocardiography detects anomalous right superior vena cava drainage directly into the left atrium.

Why the study?

Anomalous drainage of the right superior vena cava into the left atrium can cause cyanosis despite a normal heart appearance, requiring diagnostic clarification.

Population

1-year-old girl with cyanosis and signs of a normal heart

Design

Implication

May aid noninvasive detection of rare venous anomalies; leaves open need for validation in prospective cohorts.

Key Points

Evaluate the source of systemic desaturation and unexplained cyanosis in an infant presenting with an apparently structurally normal heart.
Administered a peripheral saline contrast injection into a superficial right-hand vein of a 1-year-old female patient (N=1).
Assessed cardiac chambers using M-mode and real-time two-dimensional echocardiography, followed by confirmatory cineangiocardiography.
Saline microcavitation echoes appeared directly in the left atrium and left ventricle without prior appearance in the right atrium or right ventricle.
Cineangiocardiography confirmed the diagnosis of anomalous drainage of the right superior vena cava into the left atrium.

Population

A 1-year-old girl with unexplained cyanosis who underwent peripheral contrast echocardiography to diagnose a rare cardiac anomaly.

Intervention

Peripheral contrast echocardiography (M-mode and real time, two-dimensional) with saline injection into a superficial vein of the right hand

Outcome

Detection of anomalous drainage of the right superior vena cava into the left atriumsurrogate

Peripheral contrast echocardiography with saline injection is a useful non-invasive imaging modality for detecting anomalous systemic venous drainage into the left atrium.

Limitations

Single case report
Very rare anomaly

TOMOE et al. (1980) conducted a case report in Anomalous drainage of the right superior vena cava into the left atrium (n=1). Peripheral contrast echocardiography was evaluated on Detection of anomalous drainage via contrast echoes. Peripheral contrast echocardiography successfully detected anomalous drainage of the right superior vena cava into the left atrium by demonstrating contrast echoes directly in the left heart chambers.
