[Prevalence of heart murmurs, aortic and pulmonic stenosis in boxers presented for pre-breeding exams in Switzerland].

Boxer are predisposed to subaortic (SAS) and pulmonic stenosis (PS). To decrease the prevalence, pre-breeding cardiologic exams were performed in the last years. In our study the results of 309 pre-breeding exams of boxers presented between 1999 and 2008 were evaluated retrospectively.

Use of auscultation and Doppler echocardiography in Boxer puppies to predict development of subaortic or pulmonary stenosis.

Background: Boxers are predisposed to subaortic and pulmonic stenosis (SAS, PS). Screening of puppies may be useful in estimating the risk of their developing a defect that potentially compromises life expectancy or exercise tolerance.

Hypothesis: Presence of SAS or PS in adult Boxers can be predicted by auscultation and Doppler echocardiography at 9-10 weeks of age.

Evaluation of quantified contrast-enhanced color and power Doppler ultrasonography for the assessment of vascularity and perfusion of naturally occurring tumors in dogs.

Objective: To investigate subjective and computerized methods of evaluation of color Doppler (CD) and power Doppler (PD) ultrasonographic images (obtained before and after administration of contrast medium) for quantitative assessment of vascularity and perfusion of various naturally occurring tumors in dogs.

Sample Population: 34 tumors in 34 dogs.

Procedure: Tumors in dogs were examined via CD and PD ultrasonography before and after i.

[Possibilities of minimal invasive cardiac catheter interventions in the dog].

The therapeutic possibilities in veterinary cardiology have developed rapidly in the past few years. Whereas until recently cardiac intervention in dogs could only be performed by thoracotomy, new minimally invasive techniques are adopted. Procedures like balloondilatation of pulmonic stenosis, coil embolisation of patent ductus arteriosus, pacemaker implantation in symptomatic bradyarrhyhtmia, and palliative balloon pericardiotomy are becoming more and more established.

Ultrasound guided, pre-radiation oxygen measurements using polarographic oxygen needle electrodes in spontaneous canine soft tissue sarcomas.

Background: Poor tumour oxygenation is associated with radiation resistance. The recording of pre-treatment oxygenation status has been shown to be of prognostic relevance.

Material And Methods: Eleven dogs with spontaneously arising soft tissue sarcomas were included in this study.
