A 4-year-old boy was referred to our center for an evaluation of cyanosis. Electrocardiography (ECG) showed a tall P wave, and the axis of the frontal leads was superior.

Fig. 126.2 The atresia of the tricuspid valve is visualized in the apical
four-chamber view ( arrow ). Also, there is a large ventricular septal defect ( curved arrow ) (VSD) in this view ( a , b ). The patient also had
the atresia of the main pulmonary artery and the pulmonary valve. The right and left pulmonary arteries were about 11 mm. LA left atrium, LV left ventricle, RA right atrium, RV right ventricle

Diagnosis
The patient was diagnosed with atresia of the tricuspid valve, large muscular VSD, and atresia of the main pulmonary artery and the pulmonary valve.
Comment
The patient was referred for a bidirectional Glenn shunt (hemi-Fontan procedure).
Lesson
Tricuspid atresia is one of the rare congenital anomalies, the diagnosis of which is aided by ECG. A tall P wave, in favor of the right atrial enlargement, and the superior axis of the frontal leads are the hallmarks of ECG diagnosis [ 2 , 142 ].

Diagnosis
The patient was diagnosed with tricuspid atresia, inlet VSD, and elevated mean pulmonary arterial pressure.
Comment
The infant was referred for pulmonary arterial banding.
Lesson
1. An inlet VSD is usually accompanied by other cardiac lesions.
2. Tricuspid atresia may be associated with an atretic or ste­notic pulmonary valve or without it [ 142 ].
3. A bidirectional Glenn shunt is feasible when the mean pulmonary arterial pressure is less than 15 mmHg [ 2 ].

Fig. 128.2 The three leafl ets of the tricuspid valve can be seen on
transgastric echocardiography (21°). S septal leafl et, P posterior leafl et, A anterior leafl et, LV left ventricle
Diagnosis
The patient had Ebstein’s anomaly with severe tricuspid regur­gitation and mild apical displacement of the septal leafl et of the tricuspid valve. He was also diagnosed with mild right ventricu­lar dilation and normal systolic function. Apart from palpitation, there were no signs and symptoms of right-sided failure.
Comment
The patient was referred for Holter monitoring, medical treatment, and follow-up.
Lesson
1. Supraventricular arrhythmia is a common fi nding in Ebstein’s anomaly. If this arrhythmia is not controlled by medical therapy or ablation, it becomes a relative indica­tion for surgery [ 2 ].
2. In the transgastric view with a slightly increased degree, the three leafl ets of the tricuspid valve can be visualized.

A young pregnant woman, who was asymptomatic with a very good functional class, was referred to us for further evaluation. Physical examination revealed a holosystolic murmur at the lower left sternal border, which increased with inspiration, and the wide splitting of S1. The O
2
saturation
was 93 % in room air. She was referred for an evaluation of
the cardiac cause of the systolic murmur and consultation for the continuation of pregnancy. Her body surface area was
1.6 m
. Echocardiography revealed a normal left ventricular size and systolic function and the upper limit of the normal right ventricular size with a normal right ventricular systolic function.
Ebstein’s Anomaly with Moderate Tricuspid Regurgitation, Mild Septal Displacement Ratio, and Grade 1 Right Atrial Cavity Ratio
Case 129
Fig. 129.1 The apical four-chamber view shows that the apical
displacement of the septal leafl et of the tricuspid valve is approximately 18 mm (11.2 mm/m
2
), which is suggestive of Ebstein’s anomaly. LA left atrium, LV left ventricle, RA right atrium, RV right ventricle

a septal displacement ratio smaller than 0.45 (96−78/96 = 18 %) ( c ), all of which are in favor of the mild type of the Ebstein’s deformity of the tricuspid valve
Case 129 Ebstein’s Anomaly with Moderate Tricuspid Regurgitation
427
Diagnosis
The patient was diagnosed with a mild form of Ebstein’s anomaly with moderate tricuspid regurgitation.
Comment
Because of the patient’s good functional class, absence of cyanosis, and normal right ventricular systolic function,
continuation of pregnancy was recommended [ 7 ]. Although there is the risk of right ventricular failure, arrhythmia, and paradoxical emboli, the probability of the involvement of offspring is 6 %. Ebstein’s anomaly is more probable if the mother uses benzodiazepines and lithium carbonate during pregnancy [ 7 ].

A 22-year-old woman with a history of dyspnea on exertion (functional class I) was referred to us. Physical examination showed a holosystolic murmur (grade II/VI) at the left sternal
border. Echocardiography revealed mild left ventricular sys­tolic dysfunction (left ventricular ejection fraction of 50 %) with moderate right ventricular dilation.
