Dilated cardiomyopathy with woolly hair and keratoderma is a rare inherited disorder that links three features: (1) a heart muscle disease where the main pumping chamber (the left ventricle) becomes dilated and weak, (2) woolly (tightly curled) scalp hair that is present from birth, and (3) thickened skin on the palms and soles (palmoplantar keratoderma). In most people, the heart problem appears in later childhood, teenage years, or early adulthood, while the hair and skin signs are obvious much earlier. Many cases are caused by harmful variants (mutations) in a heart-and-skin “glue” protein called desmoplakin (DSP). When this protein is faulty, cells in the heart and skin lose mechanical strength, which can lead to hair and skin changes and, over time, scarring and weakness of the heart muscle.

Carvajal syndrome is a rare inherited disease that affects the heart muscle, skin of the palms and soles (palmoplantar keratoderma), and hair (woolly, tightly curled hair). It is usually caused by harmful changes (variants) in the desmoplakin (DSP) gene. Desmoplakin is a key “riveting” protein in desmosomes, the structures that fasten heart and skin cells together. When DSP is faulty, tissues that experience constant stretch and friction—heart muscle, palms, soles, scalp—become fragile. Over time, this can lead to left-sided or left-dominant dilated/arrhythmogenic cardiomyopathy with scars (fibrosis), heart rhythm problems, and heart failure; plus thick, fissured skin on palms/soles and woolly/sparse hair that often starts at birth. In some people, early episodes look like “myocarditis” with chest pain and troponin rise (“hot phases”). AHA Journals+3PMC+3PMC+3

Dilated cardiomyopathy with woolly hair and keratoderma (Carvajal syndrome) is a genetic heart-and-skin disorder. The hair is tight and curly from birth. The skin of the palms and soles becomes abnormally thick by childhood. Later, the left ventricle of the heart enlarges and weakens, which can cause breathlessness, swelling, and irregular heartbeats. The main cause is a change in the DSP (desmoplakin) gene, which makes a protein that helps “glue” neighboring cells together in the heart and skin. When this glue is weak, microscopic damage and inflammation occur in the heart, which later heal with scar tissue, leading to a weak pump and rhythm problems. Inheritance may be autosomal recessive (two faulty copies) or autosomal dominant (one faulty copy), depending on the exact variant. MedlinePlus+2AHA Journals+2

Diagnostic tests
We group tests into Physical Examination, Manual/bedside tests, Laboratory & Pathology, Electrodiagnostic, and Imaging. Not every person needs all tests; doctors choose based on age, symptoms, and risk.
A) Physical examination
General inspection and vital signs
The doctor checks breathing, heart rate, blood pressure, and looks for leg swelling or neck-vein distension. These signs point toward heart pump weakness. J Am Acad DermatolSkin exam for palmoplantar keratoderma
Thickened, yellowish or fissured skin on palms/soles is a major clue that links the heart problem to a cardio-cutaneous syndrome. MedlinePlusHair inspection for woolly hair
Tightly curled, often coarse hair present since birth supports a syndromic diagnosis (especially with keratoderma). MedlinePlusFamily examination / pedigree review
Mapping relatives with hair/skin findings, cardiomyopathy, or sudden death helps define inheritance and guides screening. NCBI
B) Manual / bedside tests
Pulse check and rhythm strip at the bedside
Feeling an irregular pulse or capturing an immediate strip can suggest arrhythmias that need formal ECG/Holter evaluation. MedlinePlusOrthostatic vitals
Standing blood-pressure/heart-rate changes help rule out other causes of light-headedness when palpitations or fainting are reported. (Supportive to rhythm interpretation.) MedlinePlusSix-minute walk test
A simple way to quantify exercise tolerance and track heart-failure symptoms over time. (General DCM care.) J Am Acad DermatolBedside heart failure assessment

C) Laboratory & pathology
Cardiac troponin (during “hot phases”)
Troponin may rise when myocarditis-like inflammatory episodes occur in DSP cardiomyopathy; this alerts clinicians to acute injury. PMCBNP or NT-proBNP
These blood tests rise when the heart is under strain and help track heart-failure status in dilated cardiomyopathy. J Am Acad DermatolGenetic testing panels (DSP, JUP, DSC2 and other desmosomal genes)
Finding a pathogenic variant confirms the diagnosis, clarifies inheritance, and supports family screening and tailored exercise advice. NCBI+1Skin biopsy with immunostaining (selected cases)
Specialized staining can show reduced/altered desmosomal proteins (like desmoplakin) in keratoderma, supporting a desmosomal disorder. Medical JournalsEndomyocardial biopsy (only when needed)
Tissue may show inflammation and fibrosis; it is reserved for unclear cases or to distinguish other diseases because biopsy carries risks. ScienceDirectInflammation/immunity markers during hot phases
Blood tests (e.g., CRP) may support an inflammatory episode, but imaging is usually more informative. PMC
D) Electrodiagnostic
12-lead ECG
Looks for conduction delays, T-wave changes, ventricular ectopy, or low voltages that suggest cardiomyopathy or arrhythmogenic disease. NCBIAmbulatory monitoring (Holter/event recorder)
Detects day-to-day arrhythmias, including runs of ventricular tachycardia. This guides risk stratification and treatment. NCBISignal-averaged ECG (selected centers)
This specialized ECG can reveal late potentials associated with arrhythmogenic substrate in ACM. heartrhythmjournal.comExercise testing (carefully selected and monitored)
Used mainly to uncover exertional arrhythmias or ischemia; intensity must be conservative in ACM due to risk. NCBI+1
E) Imaging
Echocardiogram (ultrasound of the heart)
Shows dilated left ventricle, reduced ejection fraction, valve leakage from dilation, and sometimes right-sided involvement. It is the front-line imaging test. J Am Acad DermatolCardiac MRI (CMR) with late gadolinium enhancement (LGE)
Key test in DSP disease: often shows subepicardial or ring-like LGE in the left ventricle, indicating scarring. CMR also measures volumes and function accurately. AHA JournalsCardiac MRI during “hot phases”
May show edema and active inflammation; this helps explain chest pain and guides rest/anti-inflammatory strategies. PMCFDG-PET (selected cases)
Can detect active myocardial inflammation in DSP cardiomyopathy when CMR or symptoms suggest a hot phase. JCICutaneous imaging/dermatologic documentation
Dermoscopy and clinical photography help monitor keratoderma severity and treatment response. (Supportive for the “cardiocutaneous” link.) MedlinePlusFamily screening imaging (echo/CMR in relatives)
Because of inheritance, first-degree relatives may need periodic echo/CMR even if they feel well. NCBI
Doctors combine all these results with your story and family history. In many people, the skin and hair clues open the door to the correct heart diagnosis sooner. J Am Acad Dermatol

FAQs
1) Is Carvajal curable?
No cure yet. Care focuses on preventing arrhythmias and heart failure progression, plus skin symptom relief. Genetic therapies are in research. PMC
2) Does everyone with DSP get severe heart disease?
No. Risk varies by variant type/location, lifestyle (e.g., sports), and other factors; regular surveillance is crucial. AHA Journals
3) Why is exercise restriction so important?
High-intensity exercise raises arrhythmic risk and speeds structural damage in arrhythmogenic cardiomyopathy. PMC
4) What is a “hot phase”?
Episodes that look like myocarditis (chest pain, troponin rise, MRI edema) in DSP disease; they can foreshadow progression and need specialist care. PMC
5) When do you consider an ICD?
Based on HRS/other consensus criteria (history of sustained VT/VF, severe LV dysfunction, high-risk imaging patterns, etc.). Decision is individualized. heartrhythmjournal.com
6) Can catheter ablation replace an ICD?
No. Ablation can reduce VT/ICD shocks but does not replace the protection of an ICD against sudden death. heartrhythmjournal.com
7) Which HF drugs matter most?
The “four pillars”: ARNI/ACEi/ARB, beta-blocker, MRA, SGLT2 inhibitor—when tolerated and indicated. hfsa.org
8) Do omega-3 pills help?
Evidence is mixed; prioritize fish-rich diet. Discuss supplements with your team given possible AF risks at higher doses. PubMed
9) Does CoQ10 help?
Some trials suggest benefit as an adjunct; it’s not a replacement for GDMT. PubMed
10) Are retinoids safe for keratoderma?
They can help but require dermatology supervision, lab monitoring, and strict pregnancy avoidance for acitretin. PubMed
11) Can topical minoxidil fix woolly hair?
Evidence of benefit exists for LIPH-related woolly hair; benefit in DSP disease is uncertain. JAMA Network
12) Do I need genetic testing?
Yes, when Carvajal/DSP disease is suspected—it confirms diagnosis and guides family screening. PMC
13) How often should I get MRI scans?
Your inherited cardiomyopathy team will personalize intervals (e.g., every 1–3 years, or sooner after a hot phase) based on risk. heartrhythmjournal.com
14) Can I have a normal life?
Many people do—with early diagnosis, exercise modification, GDMT, and appropriate device therapy when indicated. AHA Journals
15) What about pregnancy?
Pre-pregnancy counseling is essential; pregnancy increases cardiac workload and needs close, specialist supervision. AHA Journals
