Manufacturer Narrative
|
Since the device was not returned to the manufacturer and the serial number of the device is unknown, no further investigation on the device can be performed at this time.Based on the medical judgement received, the structural valve deterioration (svd) of perceval s was not related to any malfunction of the device itself.Reportedly, during redo-aortic and mitral valve replacement procedures, it has been found that the position of the mitral valve was interfered with the aortic position, which led to the deterioration of the aortic valve.As such, the valve can be excluded as a possible root cause of the reported event.Should further information be received in the future, a follow up report will be provided.Unknown device disposition.

Event Description
|
The manufacturer was informed of the following event through a published paper entitled, "left coronary ostial obstruction by a dislocated sutureless aortic valve prosthesis: redo aortic valve replacement with hybrid coronary revascularization: a case report," by seungmo yoo et al.Based on the information reported, a patient who underwent sutureless aortic valve replacement (avr) and mitral valve replacement (mvr) 4 years ago due to aortic and mitral valve stenosis visited the clinic for aggravated chest pain.Coronary angiography showed obstruction of the left main (lm) coronary ostium by a dislodged prosthetic aortic valve (perceval).In addition, there was collateral blood flow from the right coronary artery to the left anterior descending coronary artery.Computed tomography (ct) revealed that a dislodged prosthetic aortic valve had caused lm coronary artery ostium obstruction.On transthoracic echocardiography (tte), ventricular function was normal, and the function of both prosthetic valves was good.After a careful consideration of the patient¿s surgical risk, it was decided to perform redo avr and, if necessary, perform coronary artery bypass grafting (cabg).After the initiation of cardiopulmonary bypass (cpb) through cannulation on the femoral vessels, redo sternotomy and adhesiolysis were performed.Reportedly, the lm ostium was completely occluded due to the dislodged aortic prosthesis and resulting neointimal fibrous tissue ingrowth.The neointimal fibrous tissue was carefully peeled off, and the prosthesis was removed using the lasso technique.Lm endarterectomy was performed carefully, and cardioplegia was infused through the right coronary ostium to confirm patency.After confirming sufficient backflow from the left coronary ostium, conventional avr was performed.Postoperative tte showed no aortic regurgitation or paravalvular leakage.On postoperative day (pod) 6, percutaneous coronary intervention (pci) stenting was added for long-term patency.The patient was discharged on pod 9 without complications.As per medical judgment reported in the paper, based on the surgical findings, it is very likely that the sutureless valve, which was slightly staggered, fell off during the ballooning procedure.Therefore, the aorto-mitral curtain distance should be considered when performing sutureless avr in the setting of concomitant mitral valve surgery.Based on the further information and medical judgement received, the structural valve deterioration (svd) of perceval s was not related to any malfunction of the device itself.Reportedly, during redo-aortic and mitral valve replacement procedures, it has been found that the position of the mitral valve was interfered with the aortic position, which led to the deterioration of the aortic valve.

Updated fields: b4, b5, g3, g6, h2, h6.Corrected fields: b5, h6.Based on the medical judgement received, the patient is suffering from chronic kidney disease and other chronic conditions and complications observed are not related to perceval valve itself.As such, the event cannot be traced to device.Should further information be received in the future, the manufacturer will provide a follow up report.
