Coronary Artery Bypass with the Use of a Magnetic Distal Anastomotic Device: Surgical Technique and Preliminary Experience
The MVP system is a novel distal coronary anastomotic device that is quick, simple, and effective, producing consistently reliable coronary anastomoses in a wide variety of coronary bypass procedures.
Reperfusion-Induced Tachyarrhythmias Resolve With Intracoronary Verapamil
Results of a study conducted in Japan confirm that the intracoronary use of verapamil can safely and immediately terminate reperfusion-induced ventricular tachyarrhythmias (VT) with no evidence for resumption of arrhythmias after treatment.
Medtronic subsidiary to pay $110 million for breach of agreement
A Memphis jury yesterday ruled that a subsidiary of medical-device maker Medtronic “breached certain provisions of its technology agreements” with a physician […]
Arizona Heart Institute and Hospital will test a new type of medical procedure
Arizona: Researchers at the Phoenix-based Arizona Heart Institute and Hospital will test a new type of medical procedure for individuals with damaged […]
Effect of Aging and Physical Activity on Left Ventricular Compliance
A sedentary lifestyle during healthy aging is associated with decreased left ventricular compliance, leading to diminished diastolic performance. Prolonged, sustained endurance training preserves ventricular compliance with aging and may help to prevent heart failure in the elderly.
Role of Coronary Collaterals in Off-Pump and On-Pump Coronary Bypass Surgery
Collaterals protect against perioperative myocardial infarction during off-pump surgery but not during on-pump surgery and are associated with a better 1-year event-free survival.
Medical Costs and Quality of Life 10 to 12 Years After Randomization to Angioplasty or Bypass Surgery for Multivessel Coronary Artery Disease
Early differences between CABG and PTCA in costs and quality of life were no longer significant at 10 to 12 years of follow-up. CABG was cost-effective as compared with PTCA for multivessel disease.
Relation of Nonperfused Myocardial Volume and Surface Area to Left Ventricular Performance in Coronary Microembolization
After coronary ME, LV dysfunction is more closely related to the total SA than to the total volume of nonperfused microregions in the myocardium.
Long-Term Mortality of Patients With Acute Myocardial Infarction in the United States and Canada
Our results suggest, for the first time, that the more conservative pattern of care with regard to early revascularization in Canada for ST-segment elevation acute myocardial infarction may have a detrimental effect on long-term survival.
Sensitivity and Specificity of Prenatal Features of Physiological Shunts to Predict Neonatal Clinical Status in Transposition of the Great Arteries
Restriction of the FO and/or of the DA has a high specificity to predict the need for emergency neonatal care in fetuses with TGA, but the sensitivity is too low to detect all high-risk fetuses.
Relation Between Renal Dysfunction and Cardiovascular Outcomes After Myocardial Infarction
Even mild renal disease, as assessed by the estimated GFR, should be considered a major risk factor for cardiovascular complications after a myocardial infarction.
Clinical Update: Acute Coronary Syndromes
Acute Coronary Syndrome (ACS) is the term used to describe a variety of cardiac conditions including unstable angina, and myocardial infarction. Unstable angina is a condition characterized by chest pain (angina) and shortness of breath (SOB) that resolves with rest or nitroglycerine administration. Myocardial infarction includes a number of conditions that describe the extent of myocardial damage.
