Item 4.01 Changes in Registrant's Certifying Accountant.

On April 20, 2012, the Audit Committee of the Board of Directors of Tiger X Medical, Inc. (the "Company") terminated its independent registered public accounting firm, Marcum LLP ("Marcum"). On April 20, 2012, the Company’s Audit Committee appointed Anton & Chia, LLP ("A&C") as the Company’s independent registered public accounting firm effective immediately.

The principal accountant's reports of Marcum on the financial statements of the Company as of and for the years ended December 31, 2011 and December 31, 2010 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. The report for the year ended December 31, 2010 dated March 31, 2011 contained an emphasis of a matter explanatory paragraph stating that: "The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has continuing losses from operations, negative cash flows and limited cash to fund future operations. These matters raise a substantial doubt about the Company's ability to continue as a going concern. Management's plans concerning these matters are also described in Note 1. These financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or amounts and classification of liabilities that might be necessary from the outcome of this uncertainty."

During the years ended December 31, 2011 and 2010 and through the date of this Current Report, there were no disagreements with Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to Marcum's satisfaction would have caused it to make reference thereto in connection with its reports on the financial statements for such years. During the years ended December 31, 2011 and 2010 and through April 20, 2012, there were no reportable events of the type described in Item 304(a)(1)(v) of Regulation S-K.

During the years ended December 31, 2011 and 2010 and through April 20, 2012, the Company did not consult with A&C with respect to any of (i) the application of accounting principles to a specified transaction, either completed or proposed; (ii) the type of audit opinion that might be rendered on the Company's financial statements; or (iii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or an event of the type described in Item 304(a)(1)(v) of Regulation S-K. In connection with the audit of the Company’s financial statements for the year ended December 31, 2011, Marcum reported to the Company’s Audit Committee that management conducted an evaluation of the Company’s internal control environment, and given the limited controls, management determined that the Company’s internal controls and controls over financial reporting were not effective as of December 31, 2011.

The Company provided Marcum with a copy of the foregoing disclosure and requested Marcum to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made therein. A copy of such letter, dated April 26, 2012, furnished by Marcum is filed as Exhibit 16.1 to this Current Report on Form 8-K.

Item 9.01 Financial Statements and Exhibits.

16.1 Letter to the SEC from Marcum, dated April 26, 2012.
