What is your risk/benefit analysis when deciding on the appropriateness and timing for discontinuation of systemic anticoagulation in patients who underwent ablation for paroxysmal atrial fibrillation with CHADS2VASc score >2?
I typically do not discontinue oral anticoagulation in post-ablation patients with paroxysmal atrial fibrillation and a CHA₂DS₂-VASc score of >2. Catheter ablation is not considered a "cure" for atrial fibrillation; therefore, there is always a risk of recurrent arrhythmia. The patient may be asympt...
In adults ≥80 years with TSH 6–10 mIU/L and minimal symptoms, do you initiate levothyroxine, monitor, or avoid treatment entirely?
I tend to check free T4 in this situation. Aging is associated with some elevation in TSH value up to 10 mIU/L with normal free T4, and in those patients, levothyroxine is not needed. In some patients, I have seen it rise above 10 with normal free T4. Supplementing levothyroxine to lower serum TSH w...

What is your clinical approach to deprescribing vs continuing low-dose aspirin used for primary prevention in older adults who are already taking this medication?
I generally continue a low-dose aspirin in patients at higher risk (e.g., diabetes, CKD, strong family history) who would be at risk for a significant reduction in quality of life were s/he to have a cardiac/vascular/cerebrovascular event, provided there is no history of significant anemia (transfus...
What is a reasonable imaging modality for older patients with pAfib already on systemic anticoagulation outpatient but presenting with suspected cardioembolic stroke and TTE without evidence of LV thrombus?
Gold standard is TEE.
What treatment do you use for stroke prevention in cervical artery dissection?
Two prior RCTs (CADISS and TREAT-CAD) investigated this topic, each with distinct designs. The CADISS trial found no statistically significant difference in primary outcomes between antiplatelet and anticoagulation therapy for extra-cranial dissection. However, the TREAT-CAD trial failed to demon...
What is your approach to the management of chronic GI bleeding from AVMs in an elderly patient on DOAC for atrial fibrillation?
I would definitely strongly consider the left atrial appendage occlusion device in these patients. While usually these devices (such as Watchman) do require anticoagulation for about 45 days until the device has an endothelial layer form on it (we usually confirm with a CT scan or TEE), there are so...
Do you obtain routine blood cultures in a non-immunocompromised patient with community-acquired pneumonia who does not meet criteria for severe CAP?
Fabre et al., PMID 31942949, categorizes "non-severe community-acquired pneumonia" as low yield for bacteremia and therefore less critical and potentially wasteful/poor stewardship to obtain blood cultures, however do note that severe community-acquired pneumonia (CAP) falls into a moderate pre-test...
How do you decide when to initiate antibiotics for superimposed bacterial pneumonia in patients with influenza?
Antibiotic therapy should not be routinely prescribed for patients with influenza and should instead be reserved for those with a specific clinical concern for secondary bacterial pneumonia. This diagnosis is best identified by clinical trajectory. Key triggers include initial improvement followed b...
