History of cardiology : Great women cardiologist of our times : Jane Somerville
The field of cardiology has seen great men over the centuries. Few women have permanently stamped their presence in that history .Jane Somerville can be termed mother of pediatric cardiology along with Maude Abbott She has a fascinating life history , having worked in Royal Brompton , Imperial and Guys London.She was mentored by pioneers like Paul wood , Blalock and others .She is primarily interested in the pediatric cardiology especially congenital heart surgeries .The classification of pulmonary atresia with VSD goes with her name.

Causes of prominent a waves in JVP
What are the causes of prominent a waves in JVP?
A prominent a wave in JVP (jugular venous pulse) indicates a resistance to right ventricular (RV) filling, which may be due to RV hypertrophy or RV inflow obstruction.
Those with RVH (right ventricular hypertrophy):
Pulmonary stenosis with intact ventricular septum
Pulmonary hypertension
Right ventricular cardiomyopathy
Due to RV inflow obstruction:
Tricuspid atresia
Tricuspid stenosis
Tumours obstructing RV inflow (Source: Cardiophile MD)

Truncus arteriosus
is a cyanotic congenital heart disease in which one single great vessel with a single semilunar valve gives rise to the aorta, pulmonary arteries and the coronary arteries. There are three morphological types depending on the origin of pulmonary arteries from the truncus. In type I, a common pulmonary trunk arises from the truncus arteriosus and divides into left and right pulmonary arteries. In type II, the two pulmonary arteries arises separately, but adjacent to each other, from the truncus. In type III, the two pulmonary arteries arise separately from either side of the truncus. The older classification had a type IV ...

Polyphasic or splintered QRS in Ebstein’s anomaly
Polyphasic or splintered QRS in Ebstein’s anomaly of tricuspid valve
(Click on the image for a larger view)
ECG in Ebstein’s anomaly of tricuspid valve showing right bundle branch block (RBBB) pattern with polyphasic and splintered QRS. The QRS is wide and Lead V2 shows rsrs pattern mimicking right bundle branch block. Lead II shows multiple small deflections (splintered QRS). The slurred S waves in lateral leads also form part of the RBBB pattern.
The duration of QRS has been linked to right ventricular enlargement and dysfunction in Ebstein’s anomaly. A larger atrialized right ventricular volume has bee...

Bundle Branch Blocks and Hemiblocks
Left bundle branch block (LBBB) is characterised by a wide QRS complex with a slurred R wave in V6 and slurred negative wave in V1 (QS complex). The initial r wave in V1 and the initial q wave in V6 which represents the initial left to right activation of the septum are absent in LBBB.
Right bundle branch block (RBBB) is characterised by rSR’ pattern in V1 and Rs pattern with slurred s in V6. The initial r in the rSR’ pattern will be lost if there is coexistent anterior wall myocardial infarction, resulting in a QR pattern. This pattern is also called QRBBB. Presence of RBBB in a patient with anterior wall myocardial ...

P Tricuspidale
Brief Notes
Notched P wave in lead II with the first peak taller than the second, indicates biatrial enlargement and has been called ‘P tricuspidale’ [1,2]. The original description of ‘P tricuspidale was by Zuckermannn R et al in 1952 [2]. The pattern is a mirror image of the ‘P mitrale’ in which the second peak is taller. P tricuspidale was noted by Gamboa R and associates in 81 percent of their thirty seven patients with tricuspid atresia, while it was seen in only two of their twenty patients with pulmonary atresia [1]. In P tricuspidale, the taller initial peak is the right atrial co...

Obligatory right to left shunt at the atrial level
Short Notes
Abstract: Obligatory right to left shunt at the atrial level occurs in tricuspid atresia, pulmonary atresia with intact interventricular septum and total anomalous pulmonary venous connection.
Obligatory right to left shunt at the atrial level means that the right to left shunt is mandated by the physiology in such a way that postnatal survival is not possible without that shunt.
Tricuspid atresia
The obligatory right to left shunt at atrial level is needed in tricuspid atresia because there is no other outlet for the right atrium. Blood returning to the right atrium from the vena cavae and coronary sinus rea...

Coronary sinus atresia
Brief Review
Abstract: Coronary sinus atresia is usually a congenital anomaly. Sometimes it is acquired, due to an AV fistula involving the middle cardiac vein which becomes grossly enlarged and impinges on the coronary sinus ostium and closes it off.
Congenital atresia of the right atrial ostium of the coronary sinus can lead to different pathways for drainage of coronary venous outflow. In some cases, coronary venous outflow may move through a persistent left superior vena cava into the left brachiocephalic vein. From the left brachiocephalic vein it reaches the right atrium through the right superior vena cava.1,2 In...

VSD with pulmonary atresia : Management issues
VSD with Pulmonary atresia is a complex form of cyanotic heart disease .Though it’s a close companion of Tetrology of Fallot physiologically, it is a vastly different entity in embryological and anatomic terms.
TOF is cono truncal anomaly where abnormal anterior displacement of conal septum result in malalignment VSD, RVOT obstruction ,aortic override and RVH.
While ,pulmonary atresia with VSD is not a primary cono truncal anomaly, the defect occurs much earlier than TOF in fetal life , where the origin of PA fails to materialise,(Fetal arteritis?) and which triggers a series of anatomical disarray in pulmona...

Cardiology MCQ 335: Hepatoclavicular view
Hepatoclavicular view is
a) LAO 40 / cranial 40
b) RAO 40 / caudal 40
c) LAO 40 / caudal 40
d) RAO 40 / cranial 40
["Click here for the answer with explanation", "Correct Answer:"]
a) LAO 40 / cranial 40
Hepatoclavicular view for angiocardiography is named so to describe to direction of the x-ray beam from the liver below to the left clavicle above. It is a shallower (LAO 40 degree) long axial oblique view with steeper (40 degree) cranial angulation. This view images the posterior aspect of ventricular septum in the atrioventricular (AV) canal region. The common AV valve can be visualised angiographically in this v...
