The HeartMate PHP (Percutaneous Heart Pump) is a second-generation transcatheter axial flow circulatory support system. The collapsible catheter pump is inserted through a 14F sheath, deployed across the aortic valve expanding to 24F and able to deliver up to 5L/min blood flow at minimum hemolytic risk. As such this device may be a valuable adjunct to percutaneous coronary intervention (PCI) of challenging lesions in high-risk patients or treatment of cardiogenic shock. This technical report discusses: (i) the HeartMate PHP concept, (ii) the implantation technique, (iii) the hemodynamic performance in an in vitro cardiovascular flow testing setup and (iv) preliminary clinical experience...

Severe aortic valve stenosis is treated traditionally with surgical valve replacement. Transcatheter aortic valve implantation (TAVI) has experienced a rapid development in the last decade. Indications for TAVI have been broadened from inoperable and high surgical risk patients to intermediate-risk patients. Mortality rates are identical after TAVI compared with surgical valve replacement in intermediate-risk patients. However, mortality is not an appropriate outcome measure for a frail older person. Quality of life, autonomy and functioning independently are probably more suitable outcomes in this frail older population...

BACKGROUND: Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. METHODS: A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed...

A 40-year-old man with osteogenesis imperfecta type I submitted to multiple procedures of surgical mitral and aortic valve replacement was referred for refractory congestive heart failure due to significant paravalvular leaks (PVLs) of both mitral and aortic prostheses. Due to perceived very high risk of a further mitroaortic surgery, transcatheter closure of PVLs under three-dimensional echocardiographic guide was performed. Thus, four Amplatzer Vascular Plug type II (St. Jude Medical Corp, St. Paul, Minnesota, USA) devices were implanted into the aortic PVLs, and three Amplatzer Vascular Plug type II devices were used to occlude a huge mitral PVL...

Transcatheter aortic valve implantation is increasingly used to treat patients with severe aortic stenosis who are at increased risk for surgical aortic valve replacement and is projected to be the preferred treatment modality. As patient selection and operator experience have improved, it is hypothesised that device-host interactions will play a more dominant role in outcome. This, in combination with the increasing number of valve types and sizes, confronts the physician with the dilemma to choose the valve that best fits the individual patient...
