For patients who have previously undergone MAZE ligation presenting with paroxysmal atrial fibrillation, how would you counsel them on the risk of stroke long-term when deciding whether or not to start or continue anticoagulation?
The decision to start or continue anticoagulation in patients with atrial fibrillation can be challenging, even after LAA closure. Specifically related to surgical closure of the LAA (excluding percutaneous LAAO, such as Watchman or Amulet), anticoagulation is still recommended indefinitely if suppo...
If prompted as an outpatient, how do you counsel patients on the rare cardiac complications of vaccinations including myocarditis?
Not a common event so the incidence is low and depends on patient exposure as to why getting vaccinated in the first place and always a good idea to discuss the risks and benefits of vaccination.
When is the best time to consider left atrial appendage closure for secondary stroke prevention in patients with atrial fibrillation?
There is equipoise about the timing of left atrial appendage closure following ischemic stroke. Due to the need to temporarily treat a patient with either dual antiplatelet or anticoagulation therapy, it is reasonable to wait until after the acute stroke period has passed to allow for healing of inf...
What is your preferred rate control agent for atrial fibrillation with rapid ventricular rate, and why?
It really depends on the clinical scenario. My preferred first line agent is short acting metoprolol. Non-dihydropyridine calcium channel blockers such as diltiazem or verapamil are also effective but should generally be avoided in patients with reduced LVEF. In hospitalized patients with tenuous he...
What is your intraprocedural approach to reducing time to reperfusion in STEMI cases: opting for culprit lesion PCI first then complete angiography, or complete angiography followed by culprit lesion PCI?
Great inquiry. A lot of it depends on the clinical acuity of the presentation as well as systems-based processes as well. If the patient is more unstable with hypotension/bradycardia or other unstable vital parameters, and the EKG is clearly pointing to a certain territory, then in order to avoid de...
Would you recommend starting a moderate-intensity statin in a patient under the age of 40 years old with HIV and a 10-year ASCVD risk estimate below 5%?
I am impressed by the benefit of statins in HIV patients but wonder if the benefit is affected by viral load (which may cause generalized inflammation and/or immune activation). I have not yet reached the point where I am ready to put low-risk, non-hypercholesteremic HIV patients on statins, but am ...
What is your approach to a patient who has a cardiac PET scan suggestive of sarcoid but no other supporting evidence of a diagnosis of sarcoid?
The diagnosis of cardiac sarcoidosis (CS) can be challenging, as non-necrotizing granulomatous inflammation is frequently patchy, and as a result, may not be present on endomyocardial biopsy even in the setting of active cardiac disease. Many institutions, including ours, attempt to avoid endomyocar...
How do you approach radiation therapy for a target volume adjacent to a WATCHMAN atrial appendage closure device?
The WATCHMAN is a non-electronic device so it does not carry the same concerns for device disruption for which we have dose limits (i.e. pacemaker, ICD, etc.). There could be a consideration of the impact of radiation dose on healing/tissue formation over the device in the period immediately after p...
Is there a role for repeat surveillance blood cultures in patients with prosthetic valve endocarditis without associated cardiac abscess after a 6 week course of antibiotic treatment without surgical intervention?
Compared to NVE, PVE is associated with high morbidity and in-hospital mortality (10-30%). Patients with PVIE who are medically managed have either no surgical indication or have surgical contraindications. 2023 ESC guidelines supported repeating the blood cultures within the first week of finishing...
