Barriers to successful left ventricular lead placement within the coronary venous anatomy may include focal stenoses, thromboses, phrenic nerve stimulation, vessel tortuosity, small vessel caliber, non-excitable tissue and valve presence. A large series describing the utilization of coronary venous angioplasty (CVAP) for relief of these issues is absent in the literature.

The real mechanism for the development of the later stages of chronic venous insufficiency still remains unclear. Venous hypervolemia and microvascular ischemia have been reported to be the consequenc...
Venous disease is more common than peripheral arterial disease. Pathophysiologically, venous disease can be associated with obstruction, reflux, or both. A common feature in chronic venous disease is ...
The growth in the experimental research of facilities to support extracorporeal circulation requires the further development of models of acute heart failure that can be well controlled and reproduced...
May-Thurner Syndrome (MTS) is a condition in which the left common iliac vein is compressed by the right common iliac artery, which may cause swelling, pain or deep venous thrombosis of the left lower...
The objective of this study was to assess the safety and efficacy of a dedicated venous stent (the VICI VENOUS STENT; VENITI, Fremont, Calif) for treatment of symptomatic iliofemoral venous outflow ob...
Ongoing registration of deep venous obstructive disease patients treated by means of percutaneous transluminal angioplasty (PTA) and stenting with or without endophlebectomy (surgical deso...
This study is a retrospective analysis where coronary arteriograms are being analyzed to determine whether the presence of tortuous coronary arteries correlate with any specific measures o...
To evaluate the role of DCB angioplasty for venous anastomotic stenosis of hemodialysis graft, investigators would like to perform randomized study comparing the results of drug- coated ba...
The purpose of this study is to determine whether percutaneous coronary angioplasty with Taxus drug eluting stent is safe and effective in the treatment of unprotected left main coronary a...
The purpose of this study is to assess the utility of nitric oxide for inhalation during left ventricular assist device (LVAD) implantation following cardiopulmonary bypass (CPB). This is ...
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.
A short vein that collects about two thirds of the venous blood from the MYOCARDIUM and drains into the RIGHT ATRIUM. Coronary sinus, normally located between the LEFT ATRIUM and LEFT VENTRICLE on the posterior surface of the heart, can serve as an anatomical reference for cardiac procedures.
A malformation of the heart in which the embryonic common PULMONARY VEIN was not incorporated into the LEFT ATRIUM leaving behind a perforated fibromuscular membrane bisecting the left atrium, a three-atrium heart. The opening between the two left atrium sections determines the degree of obstruction to pulmonary venous return, pulmonary venous and pulmonary arterial hypertension.
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
