Key Discussion Points and Insights
Kathleen's Medical Crisis Begins
-
Pregnancy Complications: Kathleen struggles with severe hyperemesis (persistent, intense nausea/vomiting) throughout pregnancy (04:00).
- “Usually morning sickness is primarily in the first trimester, but mine lasted so long...at my 26 week checkup, the midwife said to me, ‘You are still under your pre-pregnancy weight. I don’t care if you eat french fries for every meal. You have to eat food if you can keep it down.’” (Kathleen, 04:26)
-
Sudden Cardiac Arrest: Four months postpartum, Kathleen experiences a sudden, unexplained cardiac arrest on the morning of her 27th birthday, with no warning symptoms (08:00–09:00).
- "He looked over at me and he noticed that I was gasping for air and turning blue." (Kathleen, 07:10)
- "All they know is I've had a cardiac arrest, just spontaneous cardiac arrest, the morning of my 27th birthday and they don't know what to do." (Kathleen, 08:45)
-
Life-Saving Intervention: Quick response by family (her mother-in-law performs CPR), paramedics, and hospital saves her life. Kathleen is placed in a medically induced coma and undergoes therapeutic cooling—a then-innovative method to preserve neurological function (09:44).
- “They induced a coma and actually did something that at the time was pretty revolutionary...induce a coma and cool your body...now the best practice in these cases for preserving neurological function.” (Kathleen, 09:44)
- "You're not dead until you're warm and dead." (Dr. Nance, 10:28)
Aftermath: Coping with Confusion and Uncertainty
-
Memory Loss and Trauma: Kathleen wakes up with gaps in memory, struggling to process trauma reflected by her loved ones (15:04–15:50).
- “It was really hard to metabolize and process it at the time because I had no memory. And all I had were seeing the event reflected in my loved ones who were traumatized and horrified.” (Kathleen, 15:07)
-
Everyday Consequences: She gets an implanted defibrillator (ICD) but is released home with “no answers” about the underlying cause. Her ability to parent is impaired due to lifting restrictions, necessitating family support (14:00–16:00).
-
Healthcare Gaps: Kathleen describes patchy follow-up from providers, confusion over possible diagnoses, and limitations of 2008-era genetic testing and records (17:00).
- “They released me home with no answers. Basically just like a follow up, follow up in four to six weeks with a cardiologist. We'll schedule some appointments for you. Here they are. A lot of, like, we don't really know why this happens, but you have an ICD now, so you're safe if it happens again.” (Kathleen, 14:23)
The Search for Answers: A Decade of Medical Mysteries
-
Scattered Diagnoses: Multiple expert opinions bounce between postpartum cardiomyopathy, Takotsubo (“broken heart syndrome”), long QT syndrome, and SCAD (spontaneous coronary artery dissection), with no definitive consensus (21:45–24:10).
- "So if we're counting diagnoses now we've got the one doctor saying, yeah, sure, I don't know, maybe it's postpartum cardiomyopathy. And then the other doctor saying, okay, I think this is takasuba." (Kathleen, 24:04)
-
Complications of Living with ICD: The realities, mishaps, and humorous moments of living with a device (including getting “beeped” at the office for battery replacement) are discussed. Kathleen undergoes multiple device replacements due to wear, broken wires, and new technology iterations (25:20–41:00).
- “I come to realize it's coming from inside my body. So I jump up and run over to him. He's the only other person in this room with me. And I was wearing a button down blouse and I just shove my chest in his face and I'm like, do you hear me? I'm beeping.” (Kathleen, 26:17)
-
Escalating Arrhythmias and Daily Life Challenges:
-
Post-divorce, stress seems to play a role in triggering near-shocks, but growing arrhythmias and cardiac episodes lead to increasing medication and invasive procedures (beta blockers, flecainide, and eventually ablation) (33:00–60:00).
-
Kathleen’s quality of life declines; even mild exertion leaves her exhausted (51:00).
-
“If beta blockers make you feel dreadful, like you can't catch your breath, like, you know, you have no energy. Flecainide is like that, but more.” (Kathleen, 51:22)
-
The Turning Point: Meeting a Detective Doctor and Genetic Breakthrough
-
Finally, a Provider 'Closer': New cardiologist Dr. Naderi approaches Kathleen’s complex case with curiosity and validates her experiences, ordering a battery of tests including comprehensive genetic screening (64:29–65:37).
- "She is this mid-40s beautiful woman who just comes in and makes eye contact and is like, I read your chart and, wow, your case is so fascinating. There is so much going on. I want to try to get you some answers." (Kathleen, 64:33)
-
Crucial Diagnosis:
-
Genetic testing reveals an extremely rare mutation in the CACNA1C gene. This mutation is often associated with “Timothy Syndrome” (usually fatal in infants), but Kathleen’s “non-syndromic” variant apparently surfaced only in adulthood (67:06–75:43).
-
No family members carry the mutation—it's a "de novo" event, meaning it arose spontaneously.
-
“The mutation is on a gene called CACNA1C...and CACNA1C mutations mostly manifest in super severe syndromic problems in newborns and small children...There is a non-syndromic form, which is what I have.” (Kathleen, 67:06)
-
“There is nobody else in literature with that exact constellation of things.” (Kathleen, 75:43)
-
-
The Science Behind Her Heart: Detailed explanation on how calcium channel dysfunction disrupts cardiac electrical rhythm; exacerbated by common medications like Zoloft or Zofran, which Kathleen took before her crisis (77:25–78:30).
- “My body likes to take in too many calcium molecules, which means there is too much electrical charge in those cells and it doesn't release them fast enough. So then my heart doesn't want to beat right.” (Kathleen, 71:40)
-
Validation and Mixed Feelings:
-
Finally, a pediatric electrophysiologist/geneticist recognizes Kathleen’s case as severe and confirms there are no "gold standard" treatments or established research protocols for her (79:40).
-
“She just stops, and she looks at me and she's like, no, I consider your case actually quite severe...That was unbelievably validating to hear that, because it feels, even when I'm having palpitations all the time, I feel like I have to downplay it.” (Kathleen, 79:40)

Notable Quotes & Memorable Moments
-
On Being Diagnosed as a Young Woman:
- “When young women experience heart problems, they are termed atypical symptoms. And the only reason why those are called atypical is because...they are not the same symptoms that present for someone who has a heart attack caused by a blockage from plaque...because who has that? Men have that.” (Dr. Nance, 82:57)
-
Device Engineering Fails:
- “Guess who [defibrillator wires] are made for? Tall men. I am five foot two. I am lil. Like, I do not have a lot of room in my torso. So when they put the lead in, there's just like extra wire.” (Kathleen, 38:41)
-
Medical Detective Victory:
- “This is the lady that's going to find it out 100%, because she came in like a detective and was, like, curious. She's a closer.” (Anna, 64:29)
-
On Living with a Rare Disease:
- “Someone said, ‘Well, we're probably not going to get any research on this or any improvement on this because it's so rare that there's no financial gain for someone to figure it out.’ That has its own burden...there's a mental burden of living with something that, you know, no one is actively trying to solve.” (Anna, 80:53)
-
Gratitude for "Medical Nerd Memory":
- “For someone who says they don’t remember a lot of certain things that happened, you remember better than I remember.” (Anna, 86:33)

Reflections and Takeaways
- Medicine as Ongoing Detective Work: Kathleen's fourteen-year journey shows how true breakthroughs often depend on persistent self-advocacy, evolving technology, and unusually attentive providers.
- Systemic Gaps Highlighted: Differential care, device design bias (“made for tall men”), cost/access barriers to genetic testing, and the exclusion of rare diseases from mainstream research compound the struggles for patients like Kathleen.
- Emotional & Social Cost: The episode thoughtfully explores how medical mysteries don’t just affect health—they shape social relationships, reproductive autonomy, mental health, and personal identity.
- Power of Genetic Medicine: While cutting-edge genetic testing provided an answer, it didn’t guarantee a cure, highlighting both the promise and frustration of precision medicine for “orphans” (rare disease patients).
Listener Information & Calls to Action
-
Key PSA:
