How do you decide the right time for MitraClip intervention in patients with symptomatic heart failure and severe mitral regurgitation who are on maximally tolerated GDMT?
When evaluating these patients, it is always important to consider a multidisciplinary approach inclusive of general cardiologists, imaging experts for MR quantification, and most importantly, heart failure and electrophysiology colleagues. I ensure that the patient is seen by our HF colleagues to t...
How long should patients with atrial fibrillation who are already on systemic anticoagulation and are status post TAVR and PCI 6 months ago remain on Plavix?
If PCI was done for a plaque rupture event I.e. ACS, then DOAC + plavix for a year is the current SOC. For non ACS PCI, DOAC + plavix for 6 months, followed by DOAC mono Rx is a reasonable option.
Which class(es) of antihypertensives do you recommend for first-line therapy for hypertension in severe aortic stenosis?
Most beneficial data on ACE inhibitors.B blockers are to be avoided if associated AR but prior apparent contradiction is no longer valid and some benefit in outcomes based on their effects. Exact Aortic Stenosis substrate and comorbidities to determine which drugs to benefit. ARB's role is probably ...
What would be your approach to percutaneous intervention for acute plaque rupture and cardiogenic shock for a patient with cirrhosis and severe thrombocytopenia?
Thrombocytopenia is not an absolute contraindication to indicated percutaneous coronary intervention (PCI) and the antiplatelet therapy which it obligates. In a scenario such as this one -- cardiogenic shock complicating an acute myocardial infarction -- PCI is indicated as a life-saving procedure. ...
Is there a specific INR cut-off value that would prompt you to consider administering vitamin K for patients with mechanical valves requiring urgent non-cardiac surgery and if so, what would be your starting dose?
For urgent surgery that could result in significant bleeding, I would give vitamin K if the INR was 1.6 or higher. I would avoid high doses of vitamin K so as to allow more rapid anticoagulation post-op. Usually one dose of 5mg is enough. I would start low molecular weight heparin post op until INR ...
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...
Is there any difference between colchicine 0.5mg vs 0.6 mg for high risk coronary artery disease?
Based on my subjective practice, no significant difference (have used both formulations). Any others have any different/similar experiences?
Do you think that home INR monitoring is a feasible option for elderly, frail patients with atrial fibrillation on VKA treatment, given variations in socioeconomic status and access to care?
Whenever possible, I prescribe home INR monitoring with appropriate equipment. This allows me to monitor my patients on a weekly basis, rather than on a monthly basis at best. Unfortunately, insurance reimbursement is not standard for this equipment, and many patients are unable to obtain it. The ab...
Would you recommend statin initiation in a young adult patient (age < 40) with type 1 diabetes mellitus and LDL cholesterol levels greater than 100 without any cardiovascular risk factors?
The recommendations are to start statins in young adults with type 1 DM if duration of diabetes is over 20 years.
What is a reasonable surveillance strategy in terms of preferred imaging modality and frequency of monitoring for suspected AV bioprosthetic stenosis in patients status post SAVR?
Echocardiography is the best way to monitor the valve. Obtain baseline images in the first year after implantation. If baseline function is normal and access to care is good, it is not necessary to image every year in the first 5-7 years. The exception to this would be young individuals in whom the ...
