Insights

Balloon post-dilatation (BPD) in SAPIEN 3 transcatheter aortic valve replacement is more common in patients with less oversizing and more calcification. BPD does not increase procedural complications or 1-year adverse events like death or stroke.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Medical Devices

Background:

  • Outcomes and hemodynamics of balloon post-dilatation (BPD) for the SAPIEN 3 valve have not been previously reported.
  • Aortic stenosis management is evolving with transcatheter aortic valve replacement (TAVR) technologies.

Purpose of the Study:

  • To evaluate the impact of balloon post-dilatation (BPD) on outcomes and procedural complications in patients undergoing TAVR with the SAPIEN 3 valve.
  • To assess the safety and efficacy of BPD in intermediate and high surgical risk patients.

Main Methods:

  • The PARTNER 2 SAPIEN 3 observational study included 1,661 patients (intermediate and high surgical risk).
  • Outcomes and complications were assessed in patients who underwent BPD (n=208) versus those who did not.
  • Baseline characteristics, procedural data, and 30-day and 1-year outcomes were analyzed.

Main Results:

  • BPD was associated with significantly larger aortic valve area but also more paravalvular regurgitation.
  • No increase in permanent pacemaker, annular rupture, or valve embolization was observed with BPD.
  • While 1-year minor stroke incidence was higher in the BPD group initially, this difference was not significant after adjusting for baseline characteristics.

Conclusions:

  • Balloon post-dilatation is frequently used in patients with less oversizing and greater calcification during SAPIEN 3 TAVR.
  • BPD is not linked to increased procedural complications or adverse 1-year outcomes including death, rehospitalization, or stroke.

orthopara-Directing Activators: –CH3, –OH, –⁠NH2, –OCH3

All ortho–para directors, excluding halogens, are activating groups. These groups donate electrons to the ring, making the ring carbons electron-rich. Consequently, the reactivity of the aromatic ring towards electrophilic substitution increases. For instance, the nitration of anisole is about 10,000 times faster than the nitration of benzene. The electron-donating effect of the methoxy group in anisole activates the ortho and para positions on the ring and stabilizes the corresponding...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...
