Time	Events
April 2018	Cryptogenic stroke.
April 2018	Transthoracic echocardiography: patent foramen oval (PFO) with a large shunt (>30 bubbles).
	Transoesophageal echocardiography confirmed the diagnosis of PFO.
31 October 2018, time 0	PFO percutaneous closure 35-mm Amplatzer PFO Occluder®.
31 October 2018, +15 min	Positioning of the right disc of the device: Complete atrioventricular block (AVB), ventricular escape rhythm at 35 b.p.m. alternating with a second-degree AVB
31 October 2018, +20 min	The right and left discs of Amplatzer PFO Occluder® were consecutively collected in a sheath: normalization of AV conduction.
31 October 2018, +25 min	Decision to implant a smaller Amplatzer PFO Occluder® 30 mm:
	Good positioning, no recurrence of AVB.
31 October 2018, +45 min	Transfer to the cardiac intensive care unit.
2 November 2018	Electrophysiological study Normal AV nodal, intra-Hisian, and infra-Hisian conduction. Location of the device in the proximity of the AV node.
5 November 2018	Discharged from hospital.
March 2019	Follow-up: asymptomatic patient.
