Decreased interstitial conspicuity suggests improvement in the fluid status of the patient . New right lung base opacities may represent atelectasis versus aspiration . A new small right - sided pleural effusion is present . There is no pneumothorax . A single lead pacemaker is again seen , with the lead ending in the right ventricle a proper position .
