Event Description
|
Medtronic received information from a literature case report regarding a (b)(6) female patient who underwent implant of a 29 mm medtronic evolut r transcatheter valve (unique device identifier number not provided).Following valve deployment, a post-dilation was performed with a 26 mm non-compliant balloon because of ¿significant¿ paravalvular regurgitation.Afterward, the regurgitation was reduced to a grade i (mild).Pre-discharge transthoracic echocardiography revealed a small aorto-right ventricular fistula, which did not require treatment.Three months later, the patient reported aggravating dyspnea at a cardiology visit.Echocardiography showed normal function of the evolut r valve, but color-flow doppler echocardiography revealed a high-velocity jet from the aortic root into the right ventricle.The patient was referred to the authors facility where angiography of the aortic root confirmed a broad fistula from the right coronary cusp into the right ventricle.Right heart catheterization revealed a left-right shunt.Subsequently, percutaneous intervention was performed and a non-medtronic ductal occluder was placed, which completely closed the fistula.No additional adverse patient effects or product performance issues were reported.

Updated information: b5.Additional information received from the corresponding physician/author stated it is thought by all the authors that the evolut r caused the fistula, but they don't know specifically how it caused the injury because they did not perform the valve implant.The corresponding physician/author also stated, "it is possible that the valve frame injured the aortic wall, and subsequently, due to high pressure in the area, this minimal lesion expanded ¿ at least that's what was detected in echocardiography." medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
