Based on the echocardiography, which one is NOT seen in this patient?

A 58-year-old male with a history of AVR, underwent implantation of a dual-chamber pacemaker from the right side of the chest. At the time of implantation, before leads screwing (Attachment of Leads to Device header) and placing the pacemaker in the pocket , the atrial lead impedance was 650 ohms. After placing the pacemaker in the pocket, suturing, and dressing the wound, reprogramming was performed. This time, the atrial lead impedance was 1750 ohms. Chest X-rays of the patient during implantation and after implantation are available.

What is the most likely diagnosis?
