What is the diagnosis?

17 y/o girl underwent catheterization for evaluation of congenital heart disease. Catheterization is shown:

Which one of the following congenital anomaly could NOT explain this catheterization course?

35 y/o man with Ebstein anomaly. ECG tracing is shown.

What is TRUE statement regarding 12 lead ECG :

A 56 years old male patient with palpitations and frequent PVCs on surface ECG with PVCs burden of 40% on Holter monitoring , referred for ablation. Below you can find the  surface electrocardiogram.

Based on the surface ECG , what is the most possible localization for PVCs.

A young woman with an antrospetal accessory pathway (AP) underwent an electrophysiology study (EPS) and ablation. Following the procedure, adenosine was administered to confirm the elimination of the AP pathway. The tracing below was recorded during the adenosine injection

Which statement is NOT correct about this tracing:

Note: The post-TAVR LBBB was transient, lasting only for 2 hours after the procedure

What is the best next step?

A 58-year-old patient with inferior STEMI. ECG is shown.

What is the rhythm? What is the reason for such a rhythm?

EP tracing is shown:

What is the best explanation for this tracing?

A middle aged patient underwent EPS and Ablation for palpitation, ECG of arrhythmia before and after Adenosine are given with a trace of EP. 

What is the most possible diagnosis?

According to 3D mapping, which option could be the etiology of AF recurrence?

A 45 y/o lady underwent RF ablation for a focal Ventricular Tachycardia. A tracing is shown.

What EP tracing show us?

A 31 years old man was admitted to hospital with Non-STEMI. He had no known coronary artery disease (CAD) risk factors, but had a history of prolonged unexplained febrile disease when he was five years old. Coronary angiography performed. Two shots are given below.

What is the most likely etiology?

Bellow you can find his echocardiogram.

What was his cardiac surgery ?
