Summary
Complete revascularization (CR) after transcatheter aortic valve implantation (TAVI) is common but does not improve outcomes compared to incomplete revascularization (ICR). These findings suggest a selective approach to CR in high-risk TAVI patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Optimal revascularization strategy post-transcatheter aortic valve implantation (TAVI) for percutaneous coronary intervention (PCI) remains unclear.
- The prognostic impact of complete revascularization (CR) versus incomplete revascularization (ICR) in TAVI patients undergoing PCI is unknown.
Purpose of the Study:
- To evaluate the long-term clinical outcomes comparing CR and ICR in patients who underwent PCI after TAVI.
Main Methods:
- Analysis of 447 patients from the Revascularization After Transcatheter Aortic Valve Implantation (REVIVAL) registry (2008-2023).
- Patients classified as CR or ICR based on residual stenosis post-PCI.
- Primary endpoint: 4-year incidence of major adverse cardiovascular events (MACE). Weighted Cox regression used for confounder adjustment.
Main Results:
- CR achieved in 70.5% of patients, ICR in 29.5%.
- Crude 4-year MACE incidence: 34.7% for CR vs. 35.0% for ICR (p=0.710).
- Adjusted analysis showed no significant difference in MACE between CR and ICR groups (34.1% vs. 32.5%; p=0.971).
Conclusions:
- Complete revascularization (CR) after TAVI was common but not associated with improved outcomes compared to incomplete revascularization (ICR).
- Results support a selective, rather than systematic, pursuit of CR in elderly, high-risk post-TAVI patients.

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
01:30Acute Coronary Syndrome I: Introduction
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
