His blood pressure is 135/87 mm Hg, pulse 52/min, and his respirations are 17/min. Coronary arteriography shows a reduced ejection fraction, 65% stenosis of the left anterior descending artery, and 75% stenosis of the left circumflex artery. Which of the following is the recommended treatment for the patient?

A 66-year-old female with hypertension and a recent history of acute ST-segment elevation myocardial infarction (STEMI) six days earlier, treated with percutaneous transluminal angioplasty (PTA), presents with sudden onset chest pain, shortness of breath, diaphoresis, and syncope. The patient’s temperature is 37℃ (98.6℉), blood pressure is 80/50 mm Hg, pulse is 125/min, respiratory rate is 12/min, and oxygen saturation is 92% on room air. On physical examination, the patient is pale and unresponsive. A cardiac exam reveals tachycardia and a pronounced holosystolic murmur loudest at the apex and radiates to the back. Lungs are clear to auscultation. Her chest X-ray shows cardiomegaly with clear lung fields. ECG is significant for ST elevations in the precordial leads (V2-V4) and low-voltage QRS complexes. An emergency transthoracic echocardiography shows a left ventricular wall motion abnormality along with a significant pericardial effusion. The patient is intubated, and aggressive fluid resuscitation is initiated. What is the next best step in management?

A. Intra-aortic balloon counterpulsation

B. Administer dobutamine 70 mcg/min IV

A 3-year-old boy is brought to his pediatrician for a regular checkup by his mother. The patient’s mother is concerned about a slight deviation of his left eye and she also notes that her child’s left eye looks strange on the photos, especially if there is a flash.

He is up to date on all vaccines and is meeting all developmental milestones. Family history is unremarkable. The eye examination shows left eye converging strabismus. The pupillary reflex cannot be elicited from an illumination of the left eye. Fundal examination reveals are shown in the picture. On testing, visual evoked potential cannot be elicited from the left retina but is normal from the right retina. MRI of the orbits shows a retina-derived tumor in the left eye with an initial spread along the intrabulbar part of the optic nerve and vitreous seeding. The other eye is completely intact. Which of the following methods of treatment is indicated for this patient?
