Streptokinase treatment of a thrombosed Björk-Shiley prosthesis in the aortic position.

Dysfunction of a mechanical prosthetic valve caused by thrombus formation is usually treated surgically. A patient with a thrombosed Björk-Shiley valve in the aortic position was treated successfully with intravenous streptokinase. The considerable improvement in the patient's clinical condition and the phonocardiographic, echocardiographic, and cinefluoroscopic evidence of normalisation of prosthetic valve function established the efficacy of thrombolytic therapy of a thrombosed prosthetic valve in this patient.

Unruptured congenital aneurysm of the left sinus of Valsalva presenting as acute right ventricular failure.

A patient with unruptured congenital aneurysm of the left coronary sinus of Valsalva presented with acute right-sided heart failure due to right ventricular outflow tract obstruction. The mechanism for such an acute presentation may have been a sudden increase in the size of the aneurysm. The surgical importance of this lesion is the combined aortocameral approach which is seldom required for correction of such aneurysms.

MRI as guide to surgical approach in tuberculous pericardial abscess. Case report.

In a 30-year-old man with tuberculous pericardial effusion and symptoms of constrictive pericarditis, 2-D echocardiography indicated localized effusion. Subsequent magnetic resonance imaging showed the effusion to be posterior and compressing the left ventricle. Guided by this information, pericardial resection with drainage of tuberculous abscess was performed via left anterior thoracotomy.

Therapeutic guidelines for congenital complete heart block presenting in pregnancy.

Congenital complete heart block presenting for the first time in pregnancy is a therapeutic challenge. Most of the reports are from an era when pacemaker therapy was in its infancy. Although isolated case reports have appeared, there are no definite guidelines for the management of such patients. We describe three cases of congenital complete heart block presenting in pregnancy. All the patients delivered normally with temporary pacing support during labor. Two of the three women remained symptomatic during the postpartum period when they were being weaned off the pacing support, so they were discharged with permanent pacemaker implantation. The third woman remained symptom-free during pregnancy, labor, and the postpartum period and was discharged without a permanent pacemaker; she is being followed with routine and 24-hour ambulatory electrocardiography. We review the literature in an attempt to formulate a therapeutic policy for such patients.

Risk factors evaluation in some cardiovascular diseases.

Cardiovascular risk factors are associated with limitations of blood fluidity. Rheological behaviour of blood in transient flow may result from the internal organization, which in turn depends upon many parameters, which may be considered as possible elements of a profiling algorithm for diagnostic and prognostic values in various pathophysiological states. This study was designed to investigate haemorheological parameters in patients being treated for hypertension, coronary heart disease and myocardial infarct. On the basis of plasma viscosity, whole blood viscosity, haematocrit, red cell aggregation and red cell deformation, the risk was evaluated. In cases of hypertension there was a significant rise in plasma viscosity, whole blood viscosity, red cell aggregation and a fall in red cell deformability. In cases of coronary disease, plasma viscosity and red cell aggregation was increased, while in patients with myocardial infarcts, where the degree of severity is greater it was found that there was a significant rise in both plasma and whole blood viscosity. Haematocrit values were unaffected in all three groups.

Acute myocardial infarction with normal coronary arteries in a case of polyarteritis nodosa: possible role of coronary artery spasm.

A 20 year old man with no previous history of heart disease presented with acute left ventricular failure following extensive anterior wall myocardial infarction. Selective angiography revealed multiple aneurysms in the renal, mesenteric and hepatic arteries with an infarct in the lower pole of the right kidney. These findings, along with the presence of circulating hepatitis B surface antigen favoured the diagnosis of polyarteritis nodosa. In view of normal coronary angiogram and absence of myocardial vasculitis, coronary vasospasm was implicated as the cause of myocardial infarction. Such an occurrence, which could have different therapeutic and diagnostic implications, has not, to our knowledge, been previously described in polyarteritis nodosa.

Unusual case of pacemaker lead migration.

Pulmonary artery migration of pacemaker lead is rare and may result in pulmonary emboli originating from the thrombus around the infected catheter and causing multiple pulmonary infarcts. We report an unusual case of pacemaker lead migration to the right pulmonary artery with septic pulmonary embolism. While being treated with intravenous Cefuroxamine, the patient had spontaneous migration of the lead to the left pulmonary artery with subsequent left pulmonary embolism.

Successful balloon valvotomy in isolated congenital tricuspid stenosis.

Isolated congenital tricuspid valve stenosis is a rare entity. The modalities of definitive treatment have been surgical repair or replacement. We present the first reported patient with congenital tricuspid stenosis successfully treated by percutaneous balloon valvotomy. This appears to be an alternative to surgery when the anatomy, as demonstrated by echocardiography, is suitable.
