14 years prior	The patient underwent mitral valve repair for a P2 prolapse (quadrangular resection and annuloplasty witd a 28-mm flexible band)
12 years prior	Transthoracic echocardiogram (TTE) showed normal left ventricular function with mild systolic anterior motion (SAM) and mild mitral regurgitation (MR)
Re-admission	The patient presented with signs of congestive heart failure. TTE revealed normal left ventricular function with significant SAM resulting in left ventricular outflow tract obstruction and severe MR
Day 6	Transoesophageal echocardiogram (TOE) demonstrated significant SAM of the anterior mitral leaflet, resulting in the detachment from the posterior mitral leaflet in mid-to-late systole with severe MR
Days 7–15	Exhaustive medical therapies were tried but intolerant or ineffective; therefore, an invasive treatment was considered necessary
Day 16	Percutaneous mitral valve edge-to-edge repair was successfully performed. TOE confirmed displacement of the leaflets’ coaptation point towards the left ventricular inflow with resolution of SAM and marked reduction of MR
Day 24	The patient was discharged home after an uneventful recovery with good haemodynamic compensation
1 year later	The patient had no cardiovascular symptoms. Follow-up TTE showed no SAM and mild MR
