Myoarchitecture and connective tissue in hearts with tricuspid atresia.
OBJECTIVE To compare the atrial and ventricular myoarchitecture in the normal heart and the heart with tricuspid atresia, and to investigate changes in the three dimensional arrangement of collagen fibrils. METHODS Blunt dissection and cell maceration with scanning electron microscopy were used to study the architecture of the atrial and ventricular musculature and the arrangement of collagen...
متن کاملTricuspid Atresia
Left ventricular dimensions and contractility were determined by echocardiography in 33 patients with tricuspid atresia in 1985 and again in 1988. Eight patients remained palliated throughout the 3-year period; neither the left ventricular end-diastolic diameter (153±15% of normal vs. 157+19%o, p=NS) nor a load-independent index of contractility (rate-corrected velocity of shortening [VCFc]/end...
متن کاملTricuspid atresia with I-transposition.
Sir, In their recent article (1987;57:543-7) on tricuspid atresia with transposition of the great arteries Warnes and Somerville emphasised the inportance of subaortic stenosis in these patients, especially those with coarctation. They suggested that the Fontan procedure was the procedure of choice in these patients but remarked that in patients with subaortic stenosis the prognosis after Fonta...
متن کاملTricuspid Atresia Presenting in Infancy
Background. The Fontan operation is the usual goal of therapy for children with tricuspid atresia. The influences of morphology and different management strategies on survival and subsequent suitability for this procedure are crucial but unstudied in an unselected population during the Fontan era. Methods and Results. The fates of 237 consecutive infants with tricuspid atresia were reviewed (19...
متن کاملPalliative Surgery in Tricuspid Atresia
Each of these cases satisfies all or most of the following criteria for tricuspid atresia with diminished pulmonary blood flow: 1. Central cyanosis. 2. Electrocardiogram: (a) normal axis or left axis deviation, (b) preponderance of left ventricular activity over right ventricular activity. The three cases of dextrocardia had right axis deviation and preponderance of lateral ventricular activity...
