Why the study?

Can TDI and cMRI accurately assess diastolic function in cats with hypertrophic cardiomyopathy compared to normal cats?

Population

6 normal Domestic Shorthair cats and 7 Maine Coon cats with moderate to severe hypertrophic cardiomyopathy

Comparison

Tissue Doppler imaging echocardiography and… vs Normal cats vs cats with HCM; also comparison of…

Design

Preclinical

Implication

TDI may aid diastolic assessment in feline HCM; leaves open cMRI utility pending prospective validation.

Structured PICO

Can TDI and cMRI accurately assess diastolic function in cats with hypertrophic cardiomyopathy compared to normal cats?

Population

6 normal Domestic Shorthair cats and 7 Maine Coon cats with moderate to severe hypertrophic cardiomyopathy (HCM) (n=13)

Intervention

Tissue Doppler imaging (TDI) echocardiography and electrocardiogram-gated gradient echo cardiac magnetic resonance imaging (cMRI)

Comparator

Normal cats vs cats with HCM; also comparison of TDI under sedation vs propofol anesthesia in HCM cats

Outcome

Peak early diastolic velocity (Em) and cMRI indices of diastolic functionsurrogate

TDI is a sensitive noninvasive method for detecting diastolic dysfunction in cats with HCM, whereas gradient echo cMRI indices did not differentiate between normal and HCM cats.
