The mechanism and severity of mitral valve (MV) regurgitation (MR) play a critical role in guiding treatment decisions. Transthoracic echocardiography (TTE) is the primary diagnostic modality for evaluating MV disease. Discordant findings on TTE can be further quantified through transesophageal echocardiography (TEE).

Background: Coronary air embolism (CAE) is a complication that can lead to catastrophic outcomes, including myocardial infarction, stroke, and death. It is reported to occur during cardiac catheterization, within a few hours after cardiac surgery, or as a result of chest trauma. This is a case report of delayed coronary air embolism following cardiac surgery.

Article Synopsis
- * The study analyzed data from 1,189 patients to assess how severe MR affects outcomes like mortality and heart complications, finding that those with severe MR faced worse health risks over a five-year period.
- * Results indicated that severe MR significantly increased the risk of mortality and the need for aortic valve replacement (AVR), but AVR greatly improved survival rates, particularly in patients with severe MR.

Primary mitral regurgitation (MR) is a pathology that alters mechanical loading on the left ventricle, triggers an array of compensatory neurohormonal responses, and induces a distinctive ventricular remodeling response known as eccentric hypertrophy. Drug therapies may alleviate symptoms, but only mitral valve repair or replacement can provide significant recovery of cardiac function and dimensions. Questions remain about the optimal timing of surgery, with 20% of patients developing systolic dysfunction post-operatively despite being treated according to the current guidelines.
