Juga dikenali sebagai: Mitral Dysplasia, MVD, MD, Congenital Mitral Valve Malformation
Ringkasnya
Mitral valve dysplasia is a rare congenital heart defect in dogs and cats where the mitral valve fails to develop properly, often leading to valve leakage or blockage. Learn about the symptoms, diagnostic tests like echocardiography, and treatment options to manage this condition.

TL;DR. Kecacatan kongenital injap mitral: regurgitasi atau stenosis dengan risiko kegagalan jantung kiri.
Injap mitral mengawal aliran di bahagian kiri jantung.
Apakah ia?
Aparatus mitral cacat. Regurgitasi mendominasi; stenosis lebih jarang. Dilatasi LA/LV dan edema paru.
Punca dan faktor risiko
Kesalahan embrio. Berbeza penyakit mitral degeneratif anjing tua. Predisposisi baka.
Tanda
- Bunyi holosistolik (kardinal)
- Batuk
- Takipnea / dispnea
- Intoleransi senaman
- Hilang selera
- Fibrilasi atrium (kadang-kadang)

Intoleransi senaman dan pernafasan berat adalah lazim.
Bagaimana doktor haiwan mendiagnosis
Auskultasi, echo Doppler (standard emas), X-ray, ECG.

Echo menilai malformasi dan darjah regurgitasi/stenosis.
Pilihan rawatan
Diuretik, vasodilator, kawalan irama; tiada pembaikan struktur farmakologi.
Prognosis
Berubah-ubah: ringan sering baik; teruk sering kegagalan awal.
Pencegahan
