How long do you recommend waiting after variceal bleeding and banding before a transesophageal echocardiogram can be performed safely?
In the exact wording of this question, the scenario that is being presented is that the patient has had a variceal hemorrhage (VH) recently and urgent banding has already been performed to stop the VH (so that the concern would be of the TEE probe knocking off a band that is actively treating an eso...
Should we routinely include geriatric functional assessments to determine candidacy for TAVR?
Studies have shown that 40-50% of older patients with severe AS and high (≥8%) or prohibitive (≥15%) risk for perioperative mortality with surgical aortic valve replacement (based on the STS score) fail to survive with improved quality of life 1 year after undergoing TAVR. This suggests that TAVR ma...
In patients presenting to the hospital with atrial fibrillation of >/= 48 hours and are started on anticoagulation, provided they spontaneously convert with AV nodal blocking agents but then revert back into AF, would you need LAA imaging before a rhythm control strategy with AADs or cardioversion?
I would approach this the same way as if the patient had never spontaneously converted. There is a risk of stroke with chemical as well as electrical cardioversion, so should factor in CHA2DS2-VASc when making that decision. If CHA2DS2-VASc is 0 and no other high-risk features (rheumatic disease, HC...
How do you approach the use of anticholinergic medications that are prescribed for patients for non-cardiac issues, given evidence that increased anticholinergic burden may elevate the risk of out-of-hospital cardiac arrest?
Diminishing vagal tone should always be approached with caution because of the potential for adverse cardiovascular outcomes. These include sudden death as well as the potential for ischemic events caused by increasing oxygen demand. However, we need to be careful not to extrapolate these concerns t...
What is a reasonable stepwise approach to diagnostic imaging when there is ongoing concern for cardiac amyloidosis?
Abnormalities on CMR are not diagnostic of cardiac Amyloidosis. Although LGE, abnormal ECV, and abnormal T1 are findings commonly seen in Cardiac amyloidosis, the absence of one or more does not rule out amyloid. In the setting of increased LV thickness and clinical suspicion of amyloid, I would hav...
Are recurrent UTIs a contraindication to SGLT2i use?
I don't view UTIs as a contraindication to SGLT2i use, but I make a risk and benefit analysis with each patient. Bacterial UTI as well as mycotic vaginal infections may be a sign that the patient has excessive glycosuria from hyperglycemia. In general, treating hyperglycemia should lessen the freque...
What factors would guide your decision to safely resume anticoagulation for atrial fibrillation following a recent intracranial hemorrhage?
Whether a patient with atrial fibrillation and an intracerebral hemorrhage should resume anticoagulation depends on whether the bleed was attributed to cerebral amyloid angiopathy (CAA). Most patients with CAA should not be on long-term (lifelong) anticoagulation. If a bleed was attributed to hypert...
Do you pursue stress testing before discharge for a patient admitted with chest pain who has negative serial high-sensitivity troponins and a low HEART score?
I usually do not since the HEART score (0-3) has such a low incidence of cardiac events in 6 weeks, and in the study, those patients were discharged. That being said, I would ensure the patient has a follow-up within a week to set up any testing that you feel is necessary to work up the chest pain.
When do you use anticoagulation over antiplatelet therapy for secondary stroke prevention in patients with LV injury or dysfunction?
First, I will observe that the recent work is a cohort study, not an RCT< and I would be careful about concluding that anticoagulation is the best approach. We have had prior trials, e.g., WARCEF and the related ESUS trials (NAVIGATE and RESPECT), and others that have looked at possible cardioemboli...
Do you use DOAC in patients with mild or moderate rheumatic mitral stenosis?
Although using DOACs in this population may be safe, these patients were excluded from the large DOAC trials. In addition, MS progresses, so what may be moderate disease today will progress rapidly in some patients. Thus, if anticoagulation is necessary and a VKA is a major issue for the patient, a ...
