AI Article Synopsis
- Patients with severe aortic valve stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) often have coronary artery disease (CAD), but the best way to manage CAD in these cases is still unclear.
- The study examined 186 patients with severe AS and categorized them based on their CAD status, finding that those with CAD affecting critical arteries had worse outcomes.
- Specifically, patients with CAD involving the left main coronary artery or proximal left anterior descending artery had a higher risk of major adverse events and mortality, and previous procedures didn't improve their prognosis.
Article Abstract
Background: A high frequency of coronary artery disease (CAD) is reported in patients with severe aortic valve stenosis (AS) who undergo transcatheter aortic valve implantation (TAVI). However, the optimal management of CAD in these patients remains unknown.
Hypothesis: We hypothesis that AS patients with TAVI complicated by CAD have poor prognosis. His study evaluates the prognoses of patients with CAD and severe AS after TAVI.
Methods: We divided 186 patients with severe AS undergoing TAVI into three groups: those with CAD involving the left main coronary (LM) or proximal left anterior descending artery (LAD) lesion (the CAD[LADp] group), those with CAD not involving the LM or a LAD proximal lesion (the CAD[non-LADp] group), and those without CAD (Non-CAD group). Clinical outcomes were compared among the three groups.
Results: The CAD[LADp] group showed a higher incidence of major adverse cardiovascular and cerebrovascular events (MACCEs) and all-cause mortality than the other two groups (log-rank p = .001 and p = .008, respectively). Even after adjustment for STS score and percutaneous coronary intervention (PCI) before TAVI, CAD[LADp] remained associated with MACCE and all-cause mortality. However, PCI for an LM or LAD proximal lesion pre-TAVI did not reduce the risk of these outcomes.
Conclusions: CAD with an LM or LAD proximal lesion is a strong independent predictor of mid-term MACCEs and all-cause mortality in patients with severe AS treated with TAVI. PCI before TAVI did not influence the outcomes.

Aneurysm rupture is a life-threatening event, yet its underlying mechanisms remain largely unclear. This study investigated the fracture properties of the thoracic aneurysmatic aorta (TAA) using the symmetry-constraint Compact Tension (symconCT) test and compared results to native and enzymatic-treated porcine aortas' tests. With age, the aortic stiffness increased, and tissues ruptured at lower fracture energy [Formula: see text].

Introduction: Calcific aortic valve disease (CAVD) is increasingly prevalent among the aging population, and there is a notable lack of drug therapies. Consequently, identifying novel drug targets will be of utmost importance. Given that type 2 diabetes is an important risk factor for CAVD, we identified key genes associated with diabetes - related CAVD via various bioinformatics methods, which provide further potential molecular targets for CAVD with diabetes.

Background: Transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is primarily performed using the transfemoral approach. However, when this approach is not feasible, the transjugular approach can be used as an alternative.

Aortic dissection (AoD) is a rare fatal condition in which tearing in the intima causes a false channel in the aorta and can lead to rupture. AoD is classified as the DeBakey classification (Types I, II, III) and Stanford classification (Types A and B). Women with underlying risk factors such as hypertension, smoking, bicuspid aortic valve, and connective tissue disorders are at risk for pregnancy-related AoD.

Background: Vascular and bleeding complications remain a concern after transfemoral transcatheter aortic valve replacement (TAVR). The impact of the sheath type on these complications remains unclear.
Methods: The prospective MARVEL registry study analyzed enrolled 500 patients undergoing large-bore transfemoral procedures and arteriotomy closure with the MANTA vascular closure device from 10 hospitals in Europe and Canada.
