A four-month-old female Labrador retriever was brought to the Tokyo University of Agriculture and Technology Animal Medical Center for examination of its main symptoms of cough, tachypnea and exercise intolerance. Upon examination, the dog was found to have cyanosis and inadequate growth. Echocardiography revealed tetralogy of Fallot. Cardiac catheterization confirmed that the main pulmonary artery was completely occluded and that blood flowed from the aorta to the pulmonary artery. Accordingly, the animal was diagnosed with extreme tetralogy of Fallot.

Journal of the American College of... May 1998We sought to investigate the mechanism of a mental stress-induced fall in left ventricular ejection fraction (LVEF) in patients with coronary artery disease.
OBJECTIVES
We sought to investigate the mechanism of a mental stress-induced fall in left ventricular ejection fraction (LVEF) in patients with coronary artery disease.
BACKGROUND
Mental stress induces a fall in LVEF in a significant proportion of patients with coronary artery disease. This is accompanied by an increase in heart rate, blood pressure and rate-pressure product. Whether the mental stress-induced fall in LVEF is due to myocardial ischemia, altered loading conditions or a combination of both is not clear.
METHODS
Left ventricular (LV) function was studied noninvasively by serial equilibrium radionuclide angiocardiography and simultaneous measurement of peak power, a relatively afterload-independent index of LV contractility, in 21 patients with coronary artery disease (17 men, 4 women) and 9 normal subjects (6 men, 3 women) at baseline, during mental stress and during exercise. Peripheral vascular resistance (PVR), cardiac output (CO), arterial and end-systolic ventricular elastance (Ea, Ees,) and ventriculoarterial coupling (V/AC) were also calculated. Patients underwent two types of mental stress-mental arithmetic and anger recall-as well as symptom-limited semisupine bicycle exercise.
RESULTS
Nine patients (43%) had an absolute fall in LVEF of > or = 5% (Group I) in response to at least one of the mental stressors, whereas the remaining patients did not (Group II). Group I and Group II patients were similar in terms of baseline characteristics. Both groups showed a significant but comparable increase in systolic blood pressure (15+/-7 vs. 9+/-10 mm Hg, p=0.12) and a slight increase in heart rate (7+/-4 vs. 8+/-7 beats/min, p=0.6) and a comparable increase in rate-pressure product (2.2+/-0.9 vs. 1.9+/-1.2 beats/min x mm Hg, p=0.6) with mental stress. However, PVR increased in Group I and decreased in Group II (252+/-205 vs. -42+/-230 dynes x s x cm(-5), p=0.006), and CO decreased in Group I and increased in Group II (-0.2+/-0.4 vs. 0.6+/-0.7 liters/min, p=0.02) with mental stress. There was no difference in the change in peak power (p=0.4) with mental stress. With exercise, an increase in systolic blood pressure, heart rate, rate-pressure product and CO and a fall in PVR were similar in both groups. Of the two mental stressors, anger recall resulted in a greater fall in LVEF and a greater increase in diastolic blood pressure. Exercise resulted in a fall in LVEF in 7 patients (33%). However, exercise-induced changes in LVEF and hemodynamic variables were not predictive of mental stress-induced changes in LVEF and hemodynamic variables. Conclusions. Abnormal PVR and Ea responses to mental stress and exercise are observed in patients with a mental stress-induced fall in LVEF. Peripheral vasoconstrictive responses to mental stress contribute significantly toward a mental stress-induced fall in LVEF.

We present clinical, haemodynamic, and angiographic data on a 48-year-old woman with a fistulous aneurysm of the ductus arteriosus. This is the first reported case of a spontaneous fistulous aneurysm of the ductus arteriosus in an adult in which an antemortem diagnosis was made. This lesion typically presents with shortness of breath, hoarseness caused by recurrent laryngeal nerve paralysis, and chest pain, and poses a critical threat to life because of progressive compression, erosion, and haemorrhage into the oesophagus or tracheobronchial tree. Fistulous aneurysm of the ductus arteriosus should be considered in the differential diagnosis of an enlarging mediastinal mass, especially when a continuous heart murmur is noted. Early definitive diagnosis and surgical repair in adults are essential for survival.

Left ventricular puncture with ventriculography was carried out in 150 cases over the past four years as an adjunct to cardiac catheterization. It proved to be a safe method of obtaining data on abnormalities of the heart. In addition, it permitted excellent visualization of the thoracic aorta and brachiocephalic vessels. Inserting the needle at the subxiphoid and directing it through the apex of the right ventricle, into the septum and then the left ventricle lessened the hazard of injury to the left coronary artery or of entering the pleural cavity that is associated with direct apical puncture. Complications and failures were few.

72 patients with congenital aortic stenosis whose ages ranged from 1 month to 15 years were under supervision for periods ranging from several months to more than 9 years. The obstruction was subvalvar in 3. Additional malformations were aortic regurgitation, persistent ductus arteriosus, coarctation of the aorta, ventricular septal defect, partial anomalous pulmonary venous drainage, and mitral stenosis. Bacterial endocarditis complicated 3. Of 5 deaths unrelated to operation, 3 were sudden. Surgical treatment was carried out in 12 patients (commissurotomy, valve replacement with or without previous commissurotomy, subvalvar resection) with 2 deaths. 52 patients remained symptom-free. Detailed investigation to assess the patient for surgical treatment is indicated if symptoms are present or electrocardiographic evidence of severe left ventricular hypertrophy appears. Commissurotomy is, where possible, deferred until an age at which valve replacement can be undertaken if the stenosis cannot be adequately relieved without causing substantial regurgitation.

Twenty-six patients in infancy and early childhood with severe pulmonary valve stenosis and intact ventricular septum are reviewed. They were selected from a larger series of 112 patients with pulmonary stenosis of any degree, on account of early onset of symptoms and the severity of the stenosis proven by cardiac catheterization and angiocardiography, at operation or at necropsy. Our criteria for severity in this series were: presence of symptoms within the first two years of life; right ventricular and right atrial hypertrophy on electrocardiography; and right ventricular pressure equal to or higher than systemic blood pressure. The warning signs prompting valvotomy are deterioration of the following features: cyanosis and dyspnoea; congestive cardiac failure; tricuspid incompetence; cardiac enlargement and pulmonary oligaemia on radiograph; and right ventricular and right atrial hypertrophy on electrocardiography. The lives of 13 patients were saved by timely valvotomy. These patients are all well six months to six years after operation. Five patients died before any operation could be performed. Eight patients died within 48 hours of operation. Had some of these patients been operated on earlier the evidence indicates that they would have had a better prognosis. Therefore the importance of early recognition, prompt treatment, and emergency valvotomy, if necessary, is emphasized.

The principle of selectivity in the roentgenology of the cardiovascular system is now firmly established. The chambers of the heart and certain vascular beds lend themselves admirably to selective catheter or needle study, without the necessity of perfusing large segments of the cardiovascular bed which are irrelevant to a particular study.A technique of percutaneous transfemoral selective ciné coronary arteriography has been developed and applied to clinical subjects. Nevertheless, selectivity has specific limitations, and the use of the selective versus the nonselective approach must be weighed in each case, with the status of the patient as well as the requirements of the diagnostic investigation taken into account in reaching a decision.
