Tiny Little Hearts Podcast is your honest, unfiltered space for the CHD (congenital heart disease / congenital heart defect) community. Whether you're a heart parent, a CHD warrior, or someone newly navigating a complex congenital heart diagnosis — this podcast was made for you.

Hosted by Katelyn McMahan, a mom of three girls whose world changed the moment she learned her youngest daughter had complex cardiac abnormalities. She searched for real stories — kids with complex CHD, single ventricle hearts, hypoplastic left heart syndrome, and other congenital heart defects— not the polished highlight reels, but the honest, raw truth of what this life actually looks like. She wanted to prepare her heart for the good, the bad, and the ugly.

Each episode features conversations with heart parents, CHD adults, providers, and others navigating the deeply real world of congenital heart disease, open heart surgery, and medical complexity. You'll hear practical advice, emotional honesty, and stories that remind you that you are not alone in this journey. Because this life is hard — and you deserve a place to feel seen.

Topics covered include: CHD diagnosis, heart surgery recovery, parenting a medically complex child, grief and resilience, NICU and PCICU experiences, fontan circulation, cardiac catheterization, and life after a congenital heart defect diagnosis.

38. Pediatric Cardiology NP to Heart Mom: Sheradon Waits Story form Both Sides of the Bed

Season 2 · Episode 38

Wednesday, September 23, 2026 • Duration 44:50

Summary:

Sheridan Waits has spent 19 years as a pediatric cardiology nurse practitioner. She's cared for hundreds of heart families in the ICU. But 13 years into her career, everything changed when her own daughter, Mabry, was diagnosed in utero with heterotaxy — a rare condition including a right-sided stomach, double outlet right ventricle, TGA, multiple VSDs, and pulmonary stenosis. Overnight, Sheridan became both provider and heart mom.

In this conversation, we talk about:

The moment Sheridan's own fetal ultrasound turned into a diagnosis she recognized before the doctor even finished explaining it
What it's like to sit in the same waiting rooms and hear the same conversations she'd walked past for years as a provider
The guilt of wondering if her own CHD history played a role
How "small victories" look different when you've watched your child fight for every milestone
What she's learned about perspective — for families in the ICU for a day, and families there for months
How faith and medicine have worked together, not against each other, in Mabry's story
Mabry today: six years old, playing soccer, chasing a backhand spring, and living fully

This episode is for anyone who has ever sat bedside and wondered how life could look normal again — and for the providers who walk beside them every day.

37. Living with HLHS as an Adult: Mental Health, Clinical Trials and Community with Kelly DiMaggio

Wednesday, September 9, 2026 • Duration 46:53

In this episode, Kelly DiMaggio joins me to talk about her life living with HLHS. Her mom didn’t receive a prenatal diagnosis. At one point, her doctors gave her 24 hours to live. Nearly four decades later, she's living a full life — married, working in finance, and dedicating her time to moving the CHD community forward. In this conversation, Kelly walks through her early medical history, the mental health weight of being "the strong one" in her family, her role in HeartWorks' groundbreaking stem cell clinical trial, and how she co-founded Project 1 in 100, a community-first movement connecting CHD patients and families across every diagnosis. This episode isn't about the heart defect — it's about the heart future. What's possible. What it looks like to grow up, grow older, and grow into a life this full.

35. Cole Wieland on Life with HLHS and Creating Half Heart Mission

Season 2 · Episode 35

Friday, August 14, 2026 • Duration 45:41

35. Cole Wieland on Life with HLHS and Creating Half Heart Mission

Two podcasters. Two heart journeys. One community.

In this episode, Katelyn sits down with Cole Wieland, founder of Half Heart Mission and a 20-year-old living with hypoplastic left heart syndrome (HLHS). Cole and Katelyn have both built platforms inside the CHD community — his from the patient side, hers from the parent side — and this conversation is the collision of those two worlds.

They trace Cole's path from a scary moment on a pickleball court to building a following of thousands sharing his story. They talk about Goldie's own HLHS diagnosis, the in-utero intervention that changed her trajectory, and how her case became Shone's complex instead. They get honest about the vulnerability and burnout that come with sharing a medical journey online, and why neither of them are chasing followers — just the right person, at the right time, who needs to hear it. And they close with their shared experience at the National CHD Advocacy Summit in DC, including Cole's interview with Senator Dick Durbin, and the piece of advice they'd both give a brand-new heart parent.

If you've ever wondered what it looks like to turn a hard diagnosis into a platform for hope, this one's for you.

Cole is a 20-year-old living with hypoplastic left heart syndrome (HLHS) and the founder of Half Heart Mission, a platform where he shares his journey with CHD to give patients and parents hope for the future. He's had three open-heart surgeries (Norwood, Glenn, Fontaine) and grew up playing competitive basketball and golf before starting his platform on TikTok, which has since grown into a large, engaged CHD community.

34. Season 2 Premiere: A Summer Recap & What's Ahead

Wednesday, August 5, 2026 • Duration 12:23

Season 2 is here! In this solo episode, Katelyn is back after a summer break to recap the season and share what's ahead for Tiny Little Hearts: CHD and Heart Mom Life.

This summer marked the first time Katelyn and her family resumed their normal travel schedule since Goldie's diagnosis — a milestone that brought unexpected waves of reflection on the past three years. Katelyn shares what it felt like to pack for a trip with drastically fewer medical supplies than before, reconnecting with family who'd never met Goldie in person, and the gratitude that comes with a season of stability.

Looking ahead, Katelyn previews what's coming in Season 2: conversations with authors and CHD foundations doing meaningful work in the advocacy space, and a new series exploring the "messy middle" of medical motherhood — the identity shifts, the fear that coexists with hope, and the reality of raising a child with CHD once the acute crises are behind you.

Katelyn also shares a personal update: Goldie is starting preschool this fall, and new episodes will now release every other week.

In this episode:

A summer travel milestone, three years in the making
Reflecting on stability, grief, and gratitude as a heart mom
A first look at Season 2: authors, foundations, and the messy middle of motherhood
What's next for the podcast schedule

33. One Year of Tiny Little Hearts Podcast: CHD and Heart Mom Life

Wednesday, June 10, 2026 • Duration 11:28

If you're a heart parent navigating congenital heart disease, you know that the journey is rarely a straight line — and neither is building a community around it. In this special solo episode, Katelyn closes out Season 1 of Tiny Little Hearts with a heartfelt thank you to the CHD parenting community that has grown around this show.

Over the past year, Tiny Little Hearts has become a space where congenital heart disease families can feel less alone, more informed, and genuinely supported. From vulnerable guest conversations to listener stories that have poured in from heart parents across the country, Season 1 has been more than Katelyn ever hoped for when she hit record on that first episode.

In this episode, Katelyn shares:

A reflection on Season 1 — the guests, the topics, and the CHD parent community moments that meant the most
A personal and honest update on why she's pausing new episode releases for the summer — and how editing last week's episode with Katie Taylor of Child Life on Call about medical parent emotional burnout made her stop and listen to her own instincts
What's coming in Season 2, launching in early August — including deeper conversations, more expert voices, and new topics for heart families
How you can support the show during the break (hint: share it with a CHD parent who needs it)

Whether you're newly diagnosed, years into your congenital heart disease journey, or somewhere in the messy middle — this episode is a reminder that you are not walking this road alone.

32. Caregiver Burnout in Medical Parents: How To Recognize It Before You Crash with Certified Child Life Specialist Katie Taylor

Season 1 · Episode 32

Wednesday, June 3, 2026 • Duration 39:03

Summary:

In this episode, Katelyn sits down with Katie Taylor — certified child life specialist, co-founder and CEO of Child Life On Call, author, speaker, and host of Inside the Children's Hospital podcast — for a deeply honest conversation about caregiver burnout.

Katie has spent over 15 years working at the bedside of children's hospitals and supporting families through some of their hardest moments, and she brings both clinical expertise and genuine warmth to this topic that doesn't get nearly enough airtime.

In this episode:

What caregiver burnout actually looks like from the bedside — and why it's so hard to recognize when you're in it
The moment a nurse gave Katelyn and her husband permission to rest during one of Goldie's hospitalizations — and what it taught her about sustainable caregiving
Why the transition home from the hospital can be more overwhelming than the hospitalization itself
The difference between traditional "treat yourself" self-care and what actually works — including the concept of "mothering yourself" (backed by research!)
Why phrases like "you're so strong" can feel isolating for medical parents, and how that experience evolves over time
Katie's three-pillar framework from trauma-informed care: safety, community, and voice — and how to use it to ride the burnout wave

30. Congenital Heart Disease & A Broken System: The Innovation That's Changing Everything

Season 1 · Episode 30

Wednesday, May 13, 2026 • Duration 47:47

In this episode, Katelyn sits down with Tim Nelson, MD, PhD and CEO of HeartWorks — a nonprofit at the forefront of congenital heart disease (CHD) innovation. What unfolds is a candid, unflinching look at why the healthcare system is failing CHD patients and families, and what it's actually going to take to change it.

The conversation covers HeartWorks' groundbreaking cell-based tissue engineering — including FDA-approved clinical trials to transplant patients' own heart muscle cells, grown from a skin biopsy, to literally rebuild damaged hearts. Tim's core philosophy: "Tissue is the issue."

They also discuss the CHD Co-op — a patient-owned data platform that matches families to clinical trials, and gives researchers a pre-qualified participant pool to dramatically accelerate timelines. Because your medical record belongs to you, not the hospital.

Key Topics Covered

What HeartWorks does and how cell-based tissue engineering works
Why "tissue is the issue" for congenital heart disease
The three phases that shaped Tim's understanding of healthcare's failures
The tension between evidence-based medicine and clinical innovation
Risk tolerance, the "principle of uncertainty," and how families and care teams navigate clinical trials together
Why moms are the most powerful force in moving the CHD community forward
The role of parent engagement in hospital care and bedside decision-making
How the CHD Co-op works and why patient-owned data changes everything
HIPAA myths: you own your medical record, not the hospital
How aggregated patient data can compress clinical trial timelines from years to weeks
Equalizing access to cutting-edge care for patients in rural America
Why thriving stories — not hospital stories — are the ones that move the CHD world forward

Wednesday, May 6, 2026 • Duration 17:02

This Mother's Day episode is dedicated to every heart mom navigating the unique weight of medical motherhood and congenital heart disease parenting.

Whether you're in a season of stability or deep in the thick of hospital life, pediatric heart surgery recovery, or CHD advocacy, this episode will remind you: you are an incredible mom, and your child is lucky to have you.
