Congenital Anomalies of the Heart 45 



tempted, but by a critical comparison of any of the following lists 

 with those in the various previous sections such information can 

 be readily gained. 



I. Cases of Single Ventricle 



(No Other Lesion) 



No symptoms seem to be characteristic ; one case had cyanosis 

 and one was dyspnoeic. The average age was slightly more than 

 lo months if we exclude Kleinschmidt's case which lived to be 64. 



Schenck (1600), Playfair (1870), Chiari (1879), Kleinschmidt (1881), 

 Jellett (1897), Baumgarth (1902), Cautley (1908), Sokolow (1910), Pen- 

 ner (1911), Gladstone & Russmann (1915). 



(a) With Defective Atrial Septum. 



Average age 2j^ months, excluding one case which lived to be 

 24 years, persistent cyanosis slightly more frequent than in the 

 preceding. 



Otto (1814), Mackel (1815), Tiedemann (1825), Mayer (1827), Thore 

 (1842), Hale (1853), Guibert (i860), Jacoby (1884), Sanger (1889), Preisz 

 (1890), Keith (1898), Rudlof (1900), Cautley (1901), Grosse (1903), 

 Paterson (1908), Girauld et Tissier (1910). 



(&) With Patent Ductus Arteriosus. 



Only two cases by Ziegenspeck (1888) and Letulle (1904); 

 the first was complicated by an atresia of the aorta which is not 

 receiving separate recognition in this group, lived 15 days; the 

 second may perhaps have had a congenital stenosis of the pul- 

 monary artery, although I have not so interpreted it ; case lived 

 16 years and died of tuberculosis. 



(c) With Atrial Septum Defective and Ductus Arteriosus Per- 

 sistent. 



Case by Kreysig (1817) lived 22 years; that of Devilliers 

 (i860) and Konstantinowitsch (1906) less than one week, each 

 of the latter had atresia of the aorta. 



(d) With Pulmonary Stenosis. 



Chemeneau (1699), Buhl (1857), Emanuel (1906) ; latter was 

 cyanotic and lived for 7 years, others were foetuses.
