Cardiac souffle is a medical term used to describe an abnormal heart sound caused by turbulent blood flow. The spelling of this word can be confusing due to its French origin. The word "souffle" is spelled with two "f" while the English equivalent is spelled with only one. The correct pronunciation of this word is [kɑrdiæk sufl], with stress on the first syllable. The "a" in "cardiac" is pronounced as the "a" in "father", and the "e" in "souffle" is silent.
Cardiac souffle refers to an abnormal heart sound that is typically heard when listening to the heart using a stethoscope. Also known as a cardiac murmur or heart murmur, it is characterized by a blowing, whooshing, or swishing sound that occurs during the cardiac cycle. This sound is produced due to turbulent blood flow within the heart or the major blood vessels near the heart.
Cardiac souffles can be caused by a variety of underlying conditions and pathologies. They can arise from structural abnormalities of the heart valves, such as valve stenosis (narrowing) or regurgitation (leakage). Other causes include congenital heart defects, heart muscle disorders (cardiomyopathies), or abnormal connections between blood vessels (as seen in certain types of heart defects).
Cardiac souffles can be classified based on their timing within the cardiac cycle (systolic, diastolic, or continuous), their location on the chest where they are heard, and their intensity or loudness. They are often graded on a scale from 1 to 6, with grade 1 being very faint and grade 6 being the loudest.
Due to the wide range of potential causes and implications, a cardiac souffle necessitates further evaluation by a medical professional, such as a cardiologist. Additional tests, including echocardiography, electrocardiography (ECG), or cardiac catheterization, may be performed to determine the underlying cause and guide appropriate treatment.

The term "cardiac souffle" has its origins in French. "Cardiac" comes from the French word "cardiaque", meaning "of or pertaining to the heart". The word "souffle" also comes from French and has various meanings, including "a whisper" or "a breath". In the context of medicine, a "souffle" refers to a blowing or hissing sound produced by the flow of blood through a narrowed or diseased heart valve. Therefore, "cardiac souffle" can be understood as the murmuring sound heard during auscultation of the heart due to abnormal blood flow.
