Thank you, Vivian, and good morning, everyone. Welcome to Nuwellis fourth quarter 2022 earnings conference call. On today's call, I will provide an overview of our fourth quarter and full year performance, and give an update on our strategic initiatives. Our Chief Financial Officer, Lynn Blake, will then provide detailed financial results before opening the call for questions, followed by my closing remarks. 2022 proved to be a year of growth for Nuwellis with 42% year-over-year revenue growth in the fourth quarter, a revenue increase of 13% sequential and an 8% revenue growth for the full year. Revenue growth in the quarter was led by our Pediatric segment, which increased 92% year-over-year. This was followed by 47% growth in our Heart Failure segment and 24% growth in our Critical Care segment. Our momentum continues to be fueled by the execution of two key growth strategies that we have mentioned in the past. First, our expansion in the field organization, especially with our clinical education specialists, or CESs. Our CESs played an important role supporting our account managers within the inpatient and outpatient facility, and I will provide more detail later in the call. The second initiative that fueled our momentum in Q4 is the growing body of clinical evidence in the last 7 months supporting the use of the Aquadex in all the three segments of our business. I'd now like to turn to the business update on our key strategic initiatives, starting with growing our clinical body of evidence. A key area for us, an investment at Nuwellis, is having a robust clinical evidence. In doing so, we have more leverage to change practice guidelines towards making Aquadex the standard of care for fluid overload and further driving clinical adoption. We are pleased to be able to announce many…

Thank you, Nestor, and good morning, everyone. Since joining Nuwellis last October, I continue to be increasingly excited about this company's future. Our Q4 revenue growth of 42% is attributed to the success of our commercial team expansion, advancements in our clinical evidence development and our tenacity in increasing market awareness of treatment options for patients with fluid overload. Turning to the Q4 financial results. Revenue for the fourth quarter was $2.3 million, representing 42% year-over-year growth and a 14% sequential increase from the third quarter of 2022. Our Pediatric Products segment once again had the strongest growth in the quarter with a 92% increase year-over-year. This was followed by 47% growth in our Heart Failure segment and 24% growth in Critical Care. Gross margin for the quarter was 56.9% of sales, an increase of 250 basis points compared to gross margin of 54.4% in the prior year. This increase was primarily driven by increased sales volume in the quarter. Selling, general and administrative expenses were $4.7 million in the fourth quarter. Compared to the fourth quarter of 2021, SG&A expenses increased by approximately $570,000 or 14%. Compared to the third quarter of 2022, SG&A expenses increased by approximately $413,000 or 10%, reflecting increased variable compensation expenses and professional fees in the fourth quarter. Fourth quarter research and development expense was $1.2 million, an increase of $70,000 or 6% relative to the fourth quarter of 2021. On a sequential quarter basis, research and development costs increased $273,000 or 29%, all related to the planned development of our new pediatric dedicated device. Total operating expenses were $5.9 million in the quarter, an increase of approximately $640,000 compared to the fourth quarter of 2021. Total operating expenses for the full year were $21.9 million, a decrease of approximately $2.1 million or 9%…

[Operator Instructions] First question comes from Jeffrey Cohen, Ladenburg Thalmann. Please go ahead.

Hi, Nestor, Lynn how're you?

How're you Jeff?

So a few questions from my end. Firstly, could you talk about SeaStar's SCD for pediatric AKI? It sounds like their submission is in, and you would anticipate being able to commercialize their unit in 2023. Could you talk about time line there? And could you talk about commercialization specific to your three channels?

Yes, Jeff, we'll be glad to answer that question. SeaStar, the approval -- they are applying for a humanitarian device extension. And as you know, FDA can be unpredictable, but we expect that they will receive the HDE sometime in the first half of this year. The second part of your question was about the commercialization. We're going to do that in a stage approach. We're going to start with our key users of the edge of the SCD device which happen to be many of them, this our top users of Aquadex into the effort. So we see a very strong strategic fit there. So we hope to be very successful once we can start commercializing the device.

Okay. Got it. And Lynn, a financial question. You talked about 47% increase in cardiac in '24 in critical care. What was the paeds number?

Paeds number was 92% for the fourth quarter year-over-year.

That's Q4 year-over-year. Okay, got it. Do you think you'll break that out next year or this year by segment?

Well, I think we'll continue to provide that color in our commentary. It's not official segment reporting from a financial standpoint, but that's how we think about our call points and our market side. So -- yes.

Okay. Okay. Got it. And when you talk about the unit that you're working on, the pediatric sensing, you talk about IDE early '24. What's left to do between now and submitting the IDE?

Well, two things. One, we need to complete the development, which is very far advanced. And then also most important is test that the performance of the device from safety and efficacy at 100%. We want to make sure that this product has the highest quality possible when we do the launch of this -- we start the IDE study. The next step that we have, the immediate next step is our pre-submission to the FDA. And this is basically a formality where we inform the FDA of what our plans are, and then we have a conversation directly with them to see what is their opinion about our plans.

And does the pre-sub meeting come earlier this year or latter this year?

Early this year. We're very soon to do that resubmission.

Got it. And then lastly, Lynn, did you call out cash use? Q4 cash use?

I didn't call out the Q4 number, but it was in the range of $4 million, Jeff.

Got it. Okay. Perfect. Thanks for taking the questions.

Yes. Thank you, Jeff.

Thank you. Next question will be from Anthony Vendetti of Maxim Group. Please go ahead.

Thank you. In terms of the console sales, how many were from new accounts versus existing accounts?

Good question, Anthony. We had about 60% were from existing accounts and the rest was in new accounts.

Okay. Great. And really nice progress in the pediatric segment and good growth across the board. Can you talk about usage rates? I think you did give the -- did you give the percent increase in the single-use consumable piece of that? And if not, I may have missed it. If you can just repeat it?

Yes. No, we did not give a breakdown of the console versus disposables. I hear what you're saying, Anthony, is something that we would be preparing for the future. But I think it would be a good metric for you to understand our growth, especially as we increase the placement of console, which is our razor, in our razor blade model.

Okay. Great. And I don't know if Dr. Jeffries is on, but I had spoken to him during my due diligence process. If he is on, can he speak to the benefits of Aquadex and then the ability to convince his peers in the benefits of using Aquadex in terms of increasing adoption?

Yes. He's not here with us right now, Anthony. But yes, that's one of the key roles that we have for him, is to be able to talk to his peers but as well as the medical societies that have influenced the guidelines.

Okay. And you said the expected time line for the REVERSE-HF study is -- can you just review that again?

Yes. We have -- our goal for this quarter, first quarter of 2023, is to have 12 sites activated. We are at nine right now. So we have communicated in the past that we expect enrollment to be about two years before we close the enrollment and start the statistical analysis.

Okay. So the other three sites you expect by the end of March?

A precise number of sites? Yes,12 sites.

Okay. Great. In about two years. Okay. Those are my questions. I'll hop back in the queue. Thanks.

Thank you.

Thank you. [Operator Instructions] Next question will be from Brooks O'Neil, Lake Street Capital Markets. Please go ahead.

Good morning, everyone. Very nice momentum in Q4. I'm just curious if you would see any evidence of continuing momentum as we have entered into 2023?

Yes. In the past, we don't give guidelines, Brooks, as you know. But yes, we're very confident that we're going to have a good quarter in Q1.

And I think the fact that Brooks, we mentioned that we now have fully staffed and filled all key positions in the field. We have a new RVP, critical CES position starting the year. And we didn't start the quarter that way. So it's a good start to the year from a commercial team perspective as well.

Great. And then I just sit here in a little bit of amazement thinking about the reality that hospitals are penalized for readmissions, and we know that CHF is one of the key areas in which readmissions are pretty common. And just curious how you sense the customer base, doctors and hospitals view using Aquadex as a way to both provide superior care to patients and prevent readmissions. Is there any sense you have of growing awareness that this is a win-win-win situation for the hospital, for the doctors, for the patients, sort of for everybody?

Great. That's right, Brooks. We just finished our national sales meeting about two weeks ago. And in that meeting, we did nothing but to train the sales organization on the economics of the cost of treating heart failure and the potential savings that we can provide hospitals and the health care system in terms of saving money due to the prevention of unreimbursed readmissions within 30 days. And in the past, we have not had the clinical evidence to prove and to show that in [indiscernible] Aquadex can save -- can reduce the number of hospitalizations and the readmission rate. Now that we have that information in the last 7 months, now we can aggressively talk about what are the economics of the hospital. And we have all that information because it's public information. We know exactly the readmission rates by hospital and we can provide an actual financial number showing the savings in number of dollars.

Pretty powerful. That's great with the drug sales organization and all this information, I'm pretty excited about the outlook for you guys this year. So good luck. I hope that plays out.

Thank you. We are as well, Brooks.

Thank you. This concludes the question-and-answer session. I'd like to turn the conference back over to Mr. Nestor Jaramillo for closing remarks.

Thank you, operator. I would like to conclude by thanking all of our stakeholders, Nuwellis employees, stockholders, physicians, the nurses, the patients and the health care workers in the field. Without your support, we would not have been able to achieve key advances in transforming the lives of patients suffering from fluid overload. So thank you for your participation and support. Have a nice day.

This call is now concluded. Thank you for attending today's presentation. You may now disconnect.
