    Frequently Asked Questions

    What exactly is McConnell's Sign?
    McConnell's Sign refers to a specific pattern seen in an echocardiogram, which is a type of ultrasound for the heart. This pattern indicates abnormal movement of the heart's right ventricle, often associated with a serious condition called pulmonary embolism, where one or more arteries in the lungs become blocked by a blood clot.
    How was McConnell's Sign discovered?
    This diagnostic indicator was first identified by Dr. Mary J. McConnell in the 1990s. Through her observations, she noticed that patients with acute pulmonary embolism showed a distinct motion in the heart's right ventricle on an echocardiogram.
    Can McConnell's Sign be seen in conditions other than pulmonary embolism?
    Yes, while it's most commonly associated with pulmonary embolism, McConnell's Sign can also be observed in other heart-related conditions. These include right ventricular dysfunction and some cases of right heart strain. However, its presence is particularly suggestive of pulmonary embolism.
    How reliable is McConnell's Sign in diagnosing pulmonary embolism?
    McConnell's Sign is considered a helpful diagnostic tool but not infallible. It has a high specificity for pulmonary embolism, meaning if the sign is present, there's a strong likelihood of the condition. However, its absence does not rule out the possibility of a pulmonary embolism. Doctors usually consider other tests and factors before making a diagnosis.
    What does an echocardiogram showing McConnell's Sign look like?
    In an echocardiogram displaying McConnell's Sign, you'd see the heart's right ventricle exhibiting abnormal movement. Specifically, the ventricle's mid-free wall shows hypokinesis or reduced movement, while the apex, or tip, remains hyperdynamic or shows increased movement.
    Is McConnell's Sign a common finding?
    McConnell's Sign is not commonly seen because it requires an echocardiogram to be conducted at a specific time when a patient is experiencing symptoms of a pulmonary embolism. Due to this timing and the need for specialized equipment and interpretation, it's considered a relatively rare finding.
    How does the discovery of McConnell's Sign impact patient care?
    The identification of McConnell's Sign has significantly impacted patient care by providing doctors with another tool to diagnose pulmonary embolism more quickly and accurately. Early diagnosis is crucial for this condition, as prompt treatment can be lifesaving. Recognizing McConnell's Sign on an echocardiogram can expedite the decision-making process for treatment.
