Summary
Severe diastolic dysfunction on echocardiogram may indicate a cardiac source of stroke, such as left atrial appendage thrombus, even in normal sinus rhythm. This finding warrants further investigation for conditions like cardiac amyloidosis.
Area of Science:
- Cardiology
- Neurology
- Hematology
Background:
- Echocardiography is crucial for identifying cardiac causes of stroke, including left ventricular thrombus, valvular vegetations, and patent foramen ovale.
- Transesophageal echocardiogram (TEE) is used when transthoracic echocardiogram (TTE) is inconclusive or clinical suspicion for cardiac sources remains.
- Severe diastolic dysfunction on TTE is typically not considered a primary indicator for stroke etiology.

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
