Assessment of right ventricle in pulmonary arterial hypertension with three-dimensional echocardiography and cardiovascular magnetic resonance.

Aim: To correlate 3-D Echo and CMR RV parameters and to verify whether they are similarly related to the clinical conditions of patients with pulmonary arterial hypertension (PAH), a disease in which the RV plays a crucial prognostic role.

Methods: We enrolled 34 consecutive PAH patients followed by our PAH clinics. All patients underwent a 3-D Echo and CMR assessment of RV volumes and functions in the same day.

Active fixation coronary sinus lead in a patient with persistence of left superior vena cava.

In patients with PLSVC, the use of an active fixation lead (like the Medtronic "Attain Stability") on the coronary sinus can lead to a successful and safe cardiac resynchronization, facilitating its positioning with a low long-term displacement rate.
