Mitral valve prolapse is the most common cause of primary mitral regurgitation. Arrhythmic mitral valve prolapse is a special entity that is characterised by ventricular arrhythmia and increased risk for sudden cardiac death. We present a 48-year old patient that was referred to our Department of Cardiology for elective invasive coronary angiography because of significant number of premature ventricular contractions observed on 24h-ECG ambulatory monitoring. Echocardiography and cardiac MRI revealed signs of arrhythmic mitral valve prolapse.

Pregnancy-associated breast cancer is defined as breast cancer diagnosed during pregnancy or in the first postpartum year. High hormons level (estrogen, progesteron and prolactin) during this specific period make structural changes, increase breast volume and density and make the diagnosis often very difficult. We present the case of 38 old women, who noted a painless breast mass during first month of breastfeeding.
