Thank you, Miranda, and good afternoon to everyone on the call. BioCardio's current efforts are focused on advancing its autologous and its allogeneic cell therapy platforms to treat significant unmet cardiovascular and pulmonary diseases, specifically ischemic heart failure, chronic myocardial ischemia, and acute respiratory distress syndrome. All of our cell-based therapies involve local delivery of the therapeutic to the heart or lungs where we intend them to act locally. This mission has not changed, and all of these programs are still viable. We had a solid second quarter of 2023, and our team delivered on the milestones promised. For our cardiac autologous cell therapy and heart failure, or BCDA01, we implemented the adaptive statistical analysis plan with a complete FDA review. We completed our submission in Japan towards approval based on existing data, and we were finally seeing a significant increase in enrollment, including a number of patients from Canada. For our cardi-amp autologous cell therapy for chronic myocardial ischemia, we continue to make progress on enrolling in the rolling cohort and ways that we can enhance the trial. And for our cardi-allogeneic cell therapy in heart failure, first patients are about to be enrolled. Biocardia also closed on a modest financing of $2.6 million, in which insiders participated, had a publication with our partner, CellProthera, on the importance of therapeutic delivery, had three invited scientific presentations, and advanced business development discussions. Q2 was a good quarter. This third quarter, we were thrown a curveball when the Data Safety Monitoring Board for the Cardioamp Heart Failure Trials or BCD01 recommended we pause enrollment in the study. We have detailed the recommendation in our July 24th press release, and I will read it for you here. Quote, based on an analysis of the trial data, the primary FS composite endpoint assessment and a supplemental analysis presented on 7-19-23, unrelated to any emergent safety events, The DSMB recommends pausing new patient enrollment and any potential crossover patient procedures pending an outcomes analysis of patients currently completing the one-year follow-up, as well as the patients completing their imminently scheduled treatment. The DSMB recommends notifying currently enrolled patients completing their treatment sequence that the trial will be paused following their scheduled treatment to assess intermediate study results. The DSMB recommends the blind not be broken at this time to protect the integrity of the outcomes yet to be collected and to ensure that the study may be restarted without compromise after completion of the one-year data analysis. End quote. It is confusing to us, as there were no treatment emergency safety issues reported, patients in aggregate appear to be showing clinical improvement, and enrollment had accelerated significantly in recent months. We have followed the Data Safety Monitoring Board recommendation. We continue to randomize and monitor patients enrolled in this clinical study in which both patients and evaluating physicians are blinded to the treatment group. We need more information to decide next steps for this program, which could be to restart the trial, to initiate a new trial protocol under the same regulatory submission, or to abandon the program completely. Today, we don't feel that the DSMB proposal to wait for 14 months to potentially restart the trial makes any sense. If we initiate a new trial protocol, there are changes we would like to include to simplify the performance of the trial, and there are changes that the FDA has expressed interest in, including specifically a change to a different functional capacity measure for the third tier of our Finkelstein-Schoenfeld composite endpoints. If there are interesting signals in the trial that support a new trial protocol with a different endpoint, our sense is we could implement this very quickly. A second trial, if it makes sense, would also address the FDA CBER desire to have two separate trials for an approval. One of our first actions on receiving the Data Safety Monitoring Board recommendations was to confirm that the Data Safety Monitoring Board review materials were correct. The only data in the trial at this interim analysis that has been well monitored or cleaned is that for the primary composite endpoint, the survival data, the major adverse cardiac event data, and the functional capacity by six-minute walk data. We engaged independent experienced data analysis and clinical consultants to review the primary endpoint analysis and secondary outcome measures. They will be able to see the information that the DSMB reviewed as well and assess whether a follow-up meeting with the DSMB is warranted. We have been advised to stay blinded during this process to preserve options should the data set be better with respect to the primary endpoints. Soon thereafter, BioCardio may have a segregated team review the primary endpoint based on the monitored clean data and the secondary endpoints based on the available unmonitored data. Additional sub-analyses on this interim data set will also likely take place to inform next steps. New material information will be shared publicly as appropriate. On June, our June submission of the cardiac cell therapy system to Japan's Pharmaceutical and Medical Device Agency, or PMDA, for a first formal consultation towards approval for the indication of ischemic heart failure with reduced ejection fraction was based on existing safety and efficacy data. The submission was reviewed and accepted by the PMDA for formal consultation with some clarifying questions which have been addressed. The PMDA consultation could take up to four months to schedule per their normal review process, although dates in September have been requested. Subsequent interactions with PMDA are expected. To our knowledge, we have a great deal more safety and efficacy data than other cardiac cell therapies approved or reported to be seeking approval soon in Japan. We have 185 procedures performed to date in the cardiac phase one, two, and three programs with good support for efficacy from the 63 patients where we have complete visibility into the data. and apparently good safety from the additional 122 procedures to which we are still blinded. There are other compelling reasons for PMDA to support approval in that the elements of the system already have first world regulatory approvals in Japan, EU, and or USA, and the procedure is minimally invasive where other cardiac cell therapy offerings in Japan require surgical open chest access to the heart. If approved, the cardiac cell therapy system has potential to be the first minimally invasive catheter-based cell therapy available in Japan. PMDA has confirmed that should we be approved, other developers of cell therapies in Japan could also be enabled to use our delivery systems if we authorize it ahead, such that an approval of cardiac cell therapy could be an advance to the field as a whole. As we work through the process of gathering more information, to decide next steps for the BCD01 program and consult with PMDA, we expect important milestones for other clinical programs. The Cardiac Therapy Trial for Chronic Myocardial Ischemia, or BCD02, is a phase three multi-center randomized double-blinded controlled study intended to include up to 343 patients at up to 40 clinical sites. The company expects to complete enrollment in the rolling cohort of five patients in the fourth quarter of 2023 and begin the randomized phase of the trial. A number of leading investigators, including both principal investigators in this trial, believe this to be the most compelling indication for this therapy. Planning for the randomization phase is already underway based on promising experience in the patients treated to date. Strategies of using the cell population analysis as a means to set patient dosing as opposed to excluding patients, and means to include more patients based on modifying baseline exclusion criteria are under consideration to enable more rapid enrollment. Six additional centers are actively being onboarded. The company's Cardiallo Allogeneic Cell Therapy for Ischemic Heart Failure, or BCDAO3 program, is a Phase I-II clinical trial encompassing 69 patients. Clinical-grade cells have been manufactured at BioCardia and are ready for use with the company's proprietary delivery system, also manufactured at BioCardia. The first clinical center has finalized its clinical study agreement and received conditional IRB approval. Cellular preparation test runs at the clinical site and the site activation vision are scheduled for this month. Patient enrollment is expected to begin in the third quarter. This study builds on three previous trials of mesenchymal stem cells in ischemic heart failure using the company's proprietary Helix delivery system, encompassing 93 patients treated with no treatment emergent serious adverse events. Previous trial results showed compelling early signals for benefit. The company's allogeneic cell therapy trial for acute respiratory distress syndrome, or BCD-04, has been deprioritized to focus current financial resources on the other programs. This decision was based on the greatly reduced population of patients with acute respiratory distress secondary to COVID. When resources permit, BioCardia intends to expand the current indication to a broader population beyond COVID-induced ARDS and to other pulmonary indications. BioCardia's Helix biotherapeutic delivery system or Helix, delivers therapeutics into the heart muscle with a penetrating helical needle from within the heart. It enables local delivery of cell and gene-based therapies, including BioCardia's own cell therapies. It remains the safest, easiest to use, and most efficient means for the delivery of cells, genes, and proteins to the heart muscle. The delivery platform includes proprietary approved steerable guide systems, approved delivery catheters, and investigational imaging navigation. Business development is active around our Helix biotherapeutic delivery platform and in other areas, and we are working to close meaningful deals by the end of the year. These deals have potential to enable us to avoid financing. Underlying our programs is extensive intellectual property. In June, the company announced that the Japan Patent Office granted a patent titled Radial and Transendocardial Delivery Catheter, with a patent term that will expire in 2034. The patent describes interventional biotherapeutic delivery catheters to deliver biologics to specific target sites within the heart chamber. The allowed claims cover BioCard's helical needle-tipped catheter technology platform in existing products and in future products in active development with enhanced features. Also in June, the European Patent Office issued an intention to grant for a patent titled site selection, entry, and update with automatic remote image annotation. The patent application describes techniques to bring previously obtained high-resolution, three-dimensional images of a patient's heart, such as from a magnetic resonance image or MRI into the cardiac catheterization procedure suite, and to merge this image with the X-ray images that the physician uses to navigate during the procedure. This approach has been compelling in preclinical studies, and is expected to further enhance targeting, ease of procedures, and data collection compared to our current procedures. In summary, we have four significant compelling clinical programs and strategic assets around our three platforms of great value. We recognize that the market share price does not reflect this. We recognize that there's disappointment and confusion from the DSMB response, but there is a wealth of data and active programs generating more data, and products are built on data. We have significant near-term catalysts ahead from each of our three cardiac programs, as well as our business development activities. I will now pass the call to David McClung, our CFO, who will review our Q2 2023 results. David?
