Interatrial Communication and Left Atrial Hypertension
Key result
The combination of left atrial hypertension and a small atrial septal defect was found to be responsible for a continuous heart murmur in three patients, with a documented left-to-right shunt.

Implication
May explain select continuous murmurs with left atrial hypertension; hypothesis-generating from case reports and needs validation.

Outcome
Cause of continuous heart murmur
The combination of left atrial hypertension and a small atrial septal defect can produce a continuous heart murmur due to a left-to-right shunt.

Ross et al. (1963) conducted a case report in Left atrial hypertension and small atrial septal defect (n=3). The combination of left atrial hypertension and a small atrial septal defect was found to be responsible for a continuous heart murmur in three patients, with a documented left-to-right shunt.
