Abnormal Morphology: Mitral Dysplasia in a Cat

Mitral dysplasia is a pathology that describes abnormal mitral valve and valve-related structures. This congenital disease, which has been diagnosed increasingly with advancing technology, creates congestive heart failure when it progresses. Although echocardiography is accepted as the primary standard at the diagnosis stage, it may not be sufficient alone, and advanced tests may be required. The prognosis of the patients is poor. A two-month-old, mixed breed, female cat has respiratory problems and anorexia symptoms. The patient, who was taken to two different clinics, was diagnosed with bronchitis. Our hospital revealed that the diagnosis was not bronchitis but congestive heart failure due to mitral dysplasia. Medical treatment was applied to reduce the symptoms in the patient. Two days after the start of the medication, the patient began to eat and was significantly active. After the patient was stabilized, the patient was handed over to the owner in order to avoid nosocomial infections and to minimize stress. There was no further news from the patient. This is the first case reported for this disease in our country. It is also important because it is a case that reveals the importance of the multisystemic approach.

Anterior Mitral Valve Orifice in a Dog

The patient was admitted to OndokuzMayıs University Animal Hospital Internal Medicine outpatient clinic with complaints of epileptic seizures and hypothyroidism. A description of the patient’s owner is available in the history information. There was no physician information. Bradycardia was found in the electrocardiography of the patient. 2-D, M-Mode, PW, CW and Color doppler examinations were performed. Left-ventricular hypokinetic and mitral and tricuspidal valve movements were observed with limited M-Mode imaging. Anterior mitral orifice of 2 mm width was detected on septal mitral valve by PW doppler and color doppler. With this orifice, the presence of regurgitant jet, which covers LA at a rate of 1/3 and was 3.2 m/sec, together with mitral regurgitation (0.5 m/sec.), was demonstrated. PISA calculations;VFR (mL/s), ERO (mm2) and RVol (mL/pulse) values were calculated as if there were mitral regurgitation and data were obtained for mild-moderate mitral regurgitation. Therefore, no operative treatment of the orifice was recommended. Mitral valve orifice is a rare pathology and this is the first report in canine veterinary practice with degenerative mitral valve disorder. We aimed to underline the possibility of mitral orifice development in degenerative mitral valve disorders, known to present with vegetations and varying degrees of prolapsus, conventionally.

A Case of Thoracic Lordosis in a Cat

A 1.8 kg, seven months old, intact, female, mix-breed cat was referred with dyspnea and paresis. Since the patient was in such a condition that she was too incapable of the operation, treatment for dyspnea was performed. The patient has abdominal enlargement. When the respiratory stress of the patient decreased, a radiograph was taken and lordosis was found. Medical treatment was applied, because the general condition was impaired. Lordosis is the excessive curvature of a certain number of vertebrae in the neck and back region. Congenital thoracic lordosis has been described as a highly progressive and low vital capacity disease in humans and cats. Because it compresses the lung, it can cause dyspnea in patients and rhythm disturbances in the heart. This case represents a severe example of untreatable and unmanageable lordosis encountered in a cat.
