Right ventricular systolic and diastolic function assessed by two-dimensional speckle tracking echocardiography in dogs with myxomatous mitral valve disease.

Yunosuke Yuchi Ryohei Suzuki Takahiro Teshima Hirotaka Matsumoto Hidekazu Koyama

The Journal of veterinary medical science 83(12) 1918-1927 2021年11月

Pulmonary hypertension (PH) is a common comorbidity in dogs with myxomatous mitral valve disease (MMVD), and can induce various changes in the right heart, such as right ventricular (RV) hypertrophy, dilatation, and dysfunction. We hypothesized th...

Investigation of the influence of manual ventilation-controlled respiration on right ventricular pressure-volume loops and echocardiographic variables in healthy anesthetized dogs.

Yunosuke Yuchi Ryohei Suzuki Takahiro Teshima Hirotaka Matsumoto Hidekazu Koyama

American journal of veterinary research 82(11) 865-871 2021年11月

OBJECTIVE: To evaluate the influence of manual ventilation-controlled respiration on right ventricular (RV) pressure-volume loop-derived and echocardiographic variables in dogs. ANIMALS: 8 healthy, anesthetized Beagles. PROCEDURES: In a prospectiv...

Pulmonary Vascular Resistance Estimated by Echocardiography in Dogs With Myxomatous Mitral Valve Disease and Pulmonary Hypertension Probability

Ryohei Suzuki Yunosuke Yuchi Haruka Kanno Takahiro Saito Takahiro Teshima Hirotaka Matsumoto Hidekazu Koyama

Frontiers in Veterinary Science 8 2021年10月

Post-capillary pulmonary hypertension (PH) is a life-threatening complication in dogs with myxomatous mitral valve disease (MMVD). An increase in pulmonary vascular resistance (PVR) is associated with post-capillary PH progression. In humans, PVR ...

Early detection of myocardial dysfunction in a cat that gradually progressed to endomyocardial form of restrictive cardiomyopathy.

Takahiro Saito Ryohei Suzuki Yunosuke Yuchi Takahiro Teshima Hirotaka Matsumoto Hidekazu Koyama

BMC veterinary research 17(1) 274-274 2021年8月

BACKGROUND: Restrictive cardiomyopathy (RCM) is a common myocardial disease in cats, characterized by diastolic dysfunction and atrial enlargement without myocardial hypertrophy. Especially, endomyocardial form of RCM, one of the subtypes in RCM, ...

Left and Right Myocardial Functionality Assessed by Two-Dimensional Speckle-Tracking Echocardiography in Cats with Restrictive Cardiomyopathy.

Ryohei Suzuki Yunosuke Yuchi Haruka Kanno Takahiro Teshima Hirotaka Matsumoto Hidekazu Koyama

Animals : an open access journal from MDPI 11(6) 2021年5月

The endomyocardial form of restrictive cardiomyopathy (EMF-RCM), a primary disorder of the myocardium, is one of the diseases with poor prognosis in cats. We hypothesized that both the left and right myocardial functional abnormalities may occur i...
