Devices and methods for ultrasound image-guided percutaneous, cardiac valve implantation and repair comprise, in combination, a plurality of devices including but not limited to an ultrasound-image guided catheter, a pericardial sheath, a cardiac-valve delivery system and an ascending aortic filter. An image-guided catheter is utilized to introduce via an introducer needle and a guide wire a pericardium portal for permitting entry from the chest wall to inside the pericardial space between the pericardial outer lining and inner lining. The pericardium portal permits the use of ultrasound vision to locate a site proximate the left ventricular apex, for introduction of a sheath via a .myocardium needle into the left ventricular space at an angle and avoiding any coronaries or vessels. A first delivery system permits placement of at least one aortic filter which collects any emboli, particulate matter, plaque and prevents such matter travelling via the ascending aorta to the brain, causing a stroke. A second delivery system permits placement of an aortic and/or mitral valve replacement or repair using several types of repair tools.
