Plain-English summary
A 3-year-old male domestic shorthair cat was brought in because he was having trouble breathing. X-rays showed fluid in his lungs and chest, and an ultrasound of his heart revealed a blockage above the mitral valve, which was causing the heart to work harder and leading to his breathing problems. This condition is known as supravalvular mitral stenosis, where a membrane obstructs normal blood flow in the heart. Treatment options may include medications to manage symptoms and improve heart function, but the specific outcome for this cat wasn't detailed.

Abstract
A 3-year-old, 4-kg, castrated male domestic shorthair cat presented with signs of progressive respiratory distress. Thoracic radiographs showed pulmonary edema and pleural effusion. Echocardiography revealed a perforate membrane immediately above the mitral valve that divided the left atrium into proximal and distal chambers. The left auricle was proximal to the dividing membrane and connected to the markedly enlarged proximal left atrial chamber, consistent with the diagnosis of supravalvular mitral stenosis (SMS). Position of the obstructing membrane relative to the left auricle distinguishes SMS from cor triatriatum sinister (CTS). In CTS, the left auricle is distal to the dividing membrane and connects to the distal left atrial chamber.
