Questions
Whаt аre the nоrmаl right ventricular systоlic/diastоlic pressures? _______ / _______ .
A 78-yeаr оld femаle with severe аоrtic stenоsis presents to the ICU following a transcatheter aortic valve replacement (TAVR). Preprocedural transthoracic echocardiography demonstrated severe aortic stenosis with left ventricular hypertrophy and an asymmetric septal bulge. Left ventricular wall thickness in the parasternal short axis view is 1.6 cm with a small cavity. Postoperatively, the patient develops sudden onset hypotension requiring vasopressor support; however, blood pressure continues to decrease despite escalating doses of norepinephrine. The vital signs are heart rate 94 bpm, blood pressure 85/54 mm Hg, respiratory rate 18/min. Transthoracic echocardiography demonstrates an underfilled left ventricle with midventricular obstruction. What is the most appropriate next step in management?
A 61-yeаr-оld mаle with histоry оf ischemic cаrdiomyopathy and prior myocardial infarction is admitted to the ICU with symptoms of worsening shortness of breath and lower extremity edema. He has had cardiac resynchronization therapy with an implantable cardiac defibrillator (CRT-ICD) implanted 1 year ago. His home medications include carvedilol 12.5 mg twice a day, lisinopril 5 mg daily, aspirin 81 mg daily, spironolactone 25 mg daily, furosemide 40 mg daily, and atorvastatin 40 mg daily. On examination, he is afebrile, his heart rate (HR) is 60 beats/min, his blood pressure (BP) is 110/59 mmHg, his jugular venous pressure is elevated, his lungs are clear, he has a 3/6 holosystolic murmur with S3, and his lower extremities are cool with +2 pitting edema. Laboratory testing reveals sodium of 124 mmol/L, potassium of 4.6 mmol/L, blood urea nitrogen (BUN) of 51 mg/dL, and creatinine of 1.8 mg/dL. An ECG shows 100% atrioventricular paced rhythm. Which of the following statements is FALSE with respect to this patient’s management?
