Heart tumours, though rare, can pose serious risks to cardiac health. One of the most common types is the left atrial myxoma, along with thrombi of various origins. These growths can reach sizes that threaten to obstruct blood flow or dislodge into the bloodstream, potentially causing strokes or pulmonary embolisms. Prompt surgical intervention, often minimally invasive, is crucial to mitigate these risks and restore cardiac function swiftly.
