Certain failing enlarged ischemic hearts are difficult to treat by mammary implants, epicardiectomy, omental grafts. A new concept and operation has been experimentally tested, based upon the omental graft’s ability to form arteriolar communications with surrounding arteries within eight days. in animals, three coronary arteries were surrounded by ameroid constrictors. Three separate omental st...
A 24 yr old white female presented with dyspnoea, orthopnoea, paroxysmal nocturnal dyspnoea, cough and fatigue. Transthoracic echocardiography revealed a sinus venosus atrial septal defect (ASD). Right heart catheterization confirmed severe pulmonary hypertension (80/37 mmHg). A chest radiograph showed enlarged pulmonary arteries with peripheral pruning. Surgical repair of the ASD and lung biop...
Dilated cardiomyopathy can be broadly defined as heart failure with an enlarged left ventricular chamber, but with no evidence of ischemic heart disease or myocardial infarction. Recent studies from patients and animal models show that dilated cardiomyopathy results in a decrease in myocardial content of adenosine-50-triphosphate (ATP) and phosphocreatine and a decrease in the capacity for mito...
Heparin-binding EGF-like growth factor (HB-EGF) is first synthesized as a membrane-anchored form (proHB-EGF), and its soluble form (sHB-EGF) is released by ectodomain shedding from proHB-EGF. To examine the significance of proHB-EGF processing in vivo, we generated mutant mice by targeted gene replacement, expressing either an uncleavable form (HBuc) or a transmembrane domain-truncated form (HB...
Beverly Blagmon lives in the School Street housing projects in southwest Yonkers, a once-vibrant manufacturing area just north of New York City long mired in unemployment and poverty. Beverly has asthma, diabetes, high blood pressure, rheumatoid arthritis, gout and an enlarged heart, and her blood has a dangerous tendency to clot spontaneously. She is 48, and she had her first heart attack in h...
A12-year-old previously healthy girl developed syncope when walking at school. When she was seen in the emergency department, her heart rate was 115 bpm, the precordial impulse was active, and a thrill was palpated. Third and fourth heart sounds were heard. A grade 4/6 systolic ejection murmur was heard at the left upper sternal border. The chest x-ray demonstrated a mildly enlarged, globular h...
