Referral Letter to Cardiology: Exertional Lightheadedness, a New Murmur and Two Echo Numbers That Disagree
[Student Name]
Purdue University Global
MN610: NP III Clinical - Primary Care Focus
Unit 6 Assignment
[Instructor Name]
[Date]
Composite patient written as a model document. Names and dates are bracketed; nothing here is a prescribing instruction.
Header
To: [cardiologist], [cardiology practice]. From: [nurse practitioner], [primary care practice]. Date: [date]. Re: [patient name], date of birth [date]. Urgency: expedited, within two weeks.
The Question
Do these findings represent severe aortic stenosis, and is she a candidate for valve intervention given her symptoms? Her valve area falls in the severe range while her gradient and velocity do not, and I would value your assessment of which to believe.
Urgency is expedited because of an exertional near-faint three weeks ago.
Supporting Data
Symptoms: three months of lightheadedness climbing stairs, relieved by rest. One near-faint while gardening, without injury. No chest pain. Mild breathlessness on two flights of stairs. No orthopnea or leg swelling.
Examination: harsh systolic murmur peaking late, loudest in the second right intercostal space and carried into both carotids; soft second heart sound. Blood pressure 128/74.
Echocardiogram, [date]: aortic valve area 0.8 cm2, mean gradient 34 mmHg, peak velocity 3.7 m/s, ejection fraction 60 percent. The valve is heavily calcified.
The discordance. The 2020 ACC/AHA valvular heart disease guideline defines severe aortic stenosis by a peak velocity of 4.0 m/s or more or a mean gradient of 40 mmHg or more, usually with a valve area of 1.0 cm2 or less (Otto et al., 2021). Her valve area meets the severe threshold; her gradient and velocity do not. With a preserved ejection fraction, this pattern can reflect low-flow, low-gradient severe stenosis, or it can reflect a measurement error in the valve area. Discordant grading of this kind is common, and further assessment, such as stroke volume index or CT calcium scoring, can help settle it (Clavel et al., 2013). Her stroke volume index was not reported.
Relevant Comorbidities
Kidney function: eGFR 58, stable over two years.
Frailty: walks independently without an aid; gait speed 0.9 m/s; lives alone; manages her own medicines and finances.
Other conditions: hypertension; osteoarthritis of both knees; no diabetes; no prior cardiac surgery.
Her goals: she wants to "keep gardening and keep driving," and she is open to a procedure if it would help her do both.
Medication Change Already Made
Her [vasodilating antihypertensive] was held on [date], because vasodilators can cause low blood pressure when outflow from the heart is fixed, and her lightheadedness might be worsened by it. Her blood pressure has stayed between 126 and 138 systolic since. Her other medications are unchanged: [list].
Shared Care
Primary care will continue to manage her blood pressure, knee pain and preventive care, and will monitor her symptoms by phone every two weeks until she is seen. She has been advised to avoid strenuous exertion and to call 911 for chest pain, fainting or severe breathlessness. I would appreciate your recommendations on whether the held medicine should be resumed or replaced, and whether a dental evaluation is needed before any valve procedure. After your assessment, I would be glad to share follow-up as you recommend.
Sign-Off
Direct line: [number]. Her next primary care visit is [date].

How this MN610 Unit 6 example is structured
Sections appear in the order a consultant reads them. The question comes first, framed so it can be answered with a yes, a no or a specific recommendation. Urgency comes second, marked as expedited and justified in a sentence by the exertional near-faint. Only evidence relevant to that question follows: symptoms, the murmur, and the echocardiogram values, with the discordance stated plainly rather than left for the reader to spot. Relevant comorbidities follow in one line each, chosen because they affect candidacy for intervention: kidney function, frailty indicators and her own stated goals. The medication section explains the one change already made. The shared-care paragraph divides the coming months between the two services. The sign-off gives a direct number and the date of her next primary care visit.

MN610 Unit 6 questions, answered
How is a referral letter different from a consult note?
A referral letter goes out with a question; a consult note comes back with an answer. The letter should be short, lead with what you need to know, and include only the evidence the specialist needs to answer it. Many students write a full history and physical instead, which buries the question under material the consultant will skim.
Should the letter include my own assessment?
Yes, briefly. State what you think is happening and why you are uncertain, since that tells the consultant where your reasoning stopped. Avoid framing it as a diagnosis you want confirmed unless that is genuinely the question. A letter that shows its working usually gets a more specific reply than one that simply requests evaluation.
What should the letter say about the waiting period?
Who is responsible for what until the consultant sees the patient. List the monitoring, medication decisions and safety advice that stay with primary care, and give the date of the next primary care contact. A referral that leaves the interval undefined is the one most likely to let a patient fall between services.
