This report describes 30 patients under the age of 30 years with rheumatic aortic stenosis, presenting with combined aortic and mitral stenosis. Three patients had additional tricuspid stenosis. Twenty-eight patients gave a history of rheumatic polyarthritis. The diagnosis was confirmed by right and left heart catheterisation in all. The murmur of aortic stenosis was not initially present in 8 ...

The field of pediatric cardiac interventions has witnessed a dramatic increase in the number and type of procedures performed. We review the most common procedures performed in the catheter laboratory. Lesions are divided according to their physiological characteristics into left-to-right shunting lesions (atrial septal defect, patent ductus arteriosus, ventricular septal defect), right-to-left...

Coronary artery anomalies include the anomalies of origin, termination, and structure or course. Coronary artery fistulas (CAFs) are classified as the anomalies of termination and are considered a major congenital anomaly and are in the subgroup of acyanotic heart disease.1 • Atrial septal defect • Ventricular septal defect • Patent ductus arteriosus • Aortic stenosis • Pulmonary stenosis • Par...

8. What is the pathophysiology of mitral stenosis? Increased left atrial pressure is necessary to push blood through a stenotic mitral valve from the left atrium into the left ventricle. Increased left atrial pressure is transmitted retrograde into the pulmonary veins and pulmonary capillaries and ultimately into the pulmonary arteries. It gives the patient a sensation of dyspnea. A left atrial...

Congenital mitral valve stenosis is a rare pathology. In this study, we aimed to present our surgical approach and successful valve repair to a case with congenital mitral valve stenosis combined with left persistent superior vena cava. Conservative surgery of the congenital mitral valve stenosis can be performed with acceptable early and midterm outcome in terms of mortality and reoperation ra...

A side-effect of intravenous isoprenaline used after cardiac surgery Intravenous administration of isoprenaline following cardiac surgery has been shown to cause an increase in existing arterial hypoxaemia. This is considered to be due to an increase in venous admixture following interference with the normal compensatory mechanism which in the presence of alveolar hypoxia tends to maintain norm...

58-year-old male sustained sudden cardiac arrest (SCA) due to ventricular fibrillation (VF) while at work and was resuscitated with shock therapy. He had prior history of coronary artery disease bypass, preexcitation, pulmonary hypertension, hyperlipidemia, Hodgkin's disease, hypothyroidism squamous cell carcinoma. His EKG showed preexcitation. Echocardiogram moderately reduced left ejection fr...

Regional lung perfusion was measured in the sitting position by 4 external detectors after intravenous injection of 133Xe in 24 patients with mitral valve disease and in 8 people with no cardiopulmonary disease acting as normal controls. Right- and left-sided heart catheterization was carried out on the patients on the following day. Mitral valve stenosis was found in 9, mitral valve regurgitat...

BACKGROUND Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. METHODS We simulated AF with different severity grades of left-sided va...
