Item 4.01                   Change in Registrant’s Certifying Accountants.

(a)         The Audit Committee of CHF Solutions, Inc. (the “Company”) recently completed a competitive process to determine the firm that will serve as the Company’s independent registered public accounting firm for the year ending December 31, 2017. On June 5, 2017, the Audit Committee determined to dismiss Ernst & Young LLP (“Ernst & Young”) as the Company’s independent registered public accounting firm effective immediately.

The reports of Ernst & Young on the Company’s consolidated financial statements as of and for the years ended December 31, 2016 and 2015 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, except that Ernst & Young’s audit report dated March 8, 2017 on the December 31, 2016 consolidated financial statements and audit report dated March 15, 2016 on the December 31, 2015 consolidated financial statements each contained an explanatory paragraph expressing substantial doubt regarding the Company’s ability to continue as a going concern.

During the years ended December 31, 2016 and 2015, and through June 5, 2017, there were no (a) disagreements with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Ernst & Young’s satisfaction, would have caused Ernst & Young to make reference to the subject matter thereof in connection with its reports for such years; or (b) reportable events, as described under Item 304(a)(1)(v) of Regulation S-K.

The Company has provided a copy of the foregoing disclosures to Ernst & Young and requested that Ernst & Young furnish it with a letter addressed to the Securities and Exchange Commission stating whether Ernst & Young agrees with the above statements. A copy of Ernst & Young’s letter, dated June 9, 2017, is filed as Exhibit 16.1 to this Form 8-K.

(b)         On June 6, 2017, the Audit Committee engaged Baker Tilly Virchow Krause, LLP (“Baker Tilly”) as the Company’s independent registered public accounting firm for the year ending December 31, 2017, effective immediately, subject to Baker Tilly’s standard client acceptance procedures.

During the years ended December 31, 2016 and 2015 and the subsequent interim period through June 6, 2017, the Company did not consult with Baker Tilly regarding any of the matters or events set forth in Item 304(a)(2) of Regulation S-K.
