where will failure of the left ventricle cause increased pressure
Diastolic heart failure Diastolic failure is characterized by an elevated diastolic pressure in the left ventricle, despite an essentially normal/physiologic end diastolic volume (EDV). Histological evidence supporting diastolic dysfunction demonstrates ventricular hypertrophy, increased interstitial collagen deposition and infiltration of the myocardium. These influences collectively lead to a decrease in distensibility and elasticity (ability to stretch) of the myocardium. As a consequence, cardiac output becomes diminished. When the left ventricular diastolic pressure is elevated, venous pressure in lungs must also become elevated too: left ventricular stiffness makes it more difficult for blood to enter it from the left atrium. As a result, pressure rises in the atrium and is transmitted back to the pulmonary venous system, thereby increasing its hydrostatic pressure and promoting pulmonary edema.[1]
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.

Pulmonary circulation From the right ventricle, blood is pumped through the semilunar pulmonary valve into the left and right main pulmonary arteries (one for each lung), which branch into smaller pulmonary arteries that spread throughout the lungs.
