Coronary microvascular dysfunction (CMD) is a new frontier in cardiovascular disease and an important contributor to myocardial ischemia. A high prevalence of CMD is shown in heart failure, however, the cause-and-effect relationship between CMD and atrial fibrillation (AF) is unknown. We hypothesize that CMD is associated with AF and increases susceptibility to the co-existence of AF and heart failure with preserved ejection fraction (HFpEF). Our study examined the relationship between CMD, AF, and HFpEF in all patients who underwent invasive coronary physiology studies for assessment of chest pain or dyspnea. CMD was defined as impaired coronary flow reserve (CFR) without obstructive coronary disease. A total of 80 patients (mean age 60±12 years, 68.8% female, median follow up of 2.2 years) were studied. Patients with AF (61%) or HFpEF (62%), or both (71%) were more likely to have CMD than those patients without these conditions. Of the patients with AF and abnormal CFR, 91% had HFpEF. CMD was a predicrsa. Transcatheter valve mechanical perforation (TVMP) in pulmonary atresia with intact ventricular septum (PAIVS) is an acceptable yet challenging alternative to radiofrequency. To evaluate and compare safety, feasibility, and efficiency of two TVMP techniques. Clinical data of neonates with PAIVS who underwent an attempt for TVMP between 2009 and 2019 were retrospectively reviewed. Patients were divided into two groups according to perforation technique using the stiff end of a percutaneous transluminal coronary angioplasty (PTCA) ordinary 0.014" wire (group A) and subsequently with the floppy tip of a chronic total occlusion (CTO) guidewire (group B). The technical aspects, procedural and discharge outcomes of both groups were compared. A total of 19 antegrade TVMP procedures (Group A, n=10, and Group B, n=9) were attempted in 18 neonates with an overall success rate of 73.7% and no procedure-related mortality. Groups' analysis showed that the introduction of CTO hardware maximized procedure success rates (P=0.002) with zero failure and misperforations (P=0.022). The significant drop in perforation time (P < 0.001) and irradiation exposure (P=0.006) allowed additional ductal stenting during the same procedure, optimizing patients' clinical outcomes and shortening overall hospital stay. Discharged patients had room air mean oxygen saturation of 91.4% (± 5.5) with no evidence of heart failure. In selected cases of PAIVS, TVMP using CTO wires is a safer, highly efficient, and simplified alternative to other mechanical perforation techniques. It substantially revolutionized the management of PAIVS in our center optimizing short-term prognosis.In selected cases of PAIVS, TVMP using CTO wires is a safer, highly efficient, and simplified alternative to other mechanical perforation techniques.

Recent improvements in devices and medications may diminish the risk of adverse events following percutaneous coronary intervention (PCI) in women. However, complex calcified coronary lesions are increasingly being encountered in clinical practice, which remain challenging for contemporary PCI. Rotational atherectomy (RA) of severely calcified lesions is an option that facilitates the technical success of PCI. We aimed to examine sex differences in long-term clinical prognoses after PCI with RA in the drug-eluting stent (DES) era. We evaluated J2T ROTA registry data from 1,090 patients with severely calcified de novo coronary artery stenoses who underwent PCI using RA at 3 hospitals between 2004 and 2015. After excluding patients who received regular hemodialysis, 788 patients, including 570 men and 218 women, were ultimately analyzed. The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE), which included death, acute coronary syndrome (ACS), and stroke. The women were significantly older, and presented more frequently with chronic kidney disease, ACS, atrial fibrillation, lower body mass indexes, and worse lipid profiles than the men. During the observation period, MACCE occurred in 197 patients (25%) (118 deaths, 29 strokes, and 50 ACS). In the unmatched population, women had a higher MACCE rate than men (hazard ratio 1.48, [95% confidence interval 1.07-2.06]). However, sex was not associated with MACCE in the propensity score-matched population. In the DES era, differences between sexes were not observed in relation to long-term MACCE in patients undergoing PCI with RA for severely calcified coronary artery stenoses.In the DES era, differences between sexes were not observed in relation to long-term MACCE in patients undergoing PCI with RA for severely calcified coronary artery stenoses. myocardial infarction (MI) remains the leading cause of death worldwide. Cell-based therapies have become potential therapeutic approaches, attempting to recover the contractility of necrotic cardiomyocytes. In the present study, we aimed to systematically evaluate experimental studies on the use of tissue-engineered amniotic membrane (hAMC) in MI treatment. a systematic review of literature published in PubMed, Embase and CENTRAL databases was conducted, until March 31, 2020, for experimental studies reporting on hAMC cell-therapy performed on LV function, MI size, paracrine effects, angiogenesis, and cell differentiation. Two reviewers selected the articles that met the inclusion criteria and disagreements were solved through a consensus. a total of 11 studies were included for data extraction. For the acute scenario, therapeutic use of hAMC after MI was capable of improving LV function in rats, mainly due to its paracrine effects (anti-apoptotic and anti-inflammatory) and associated with cardiomyocyte differentiation, MI size reduction and neo-angiogenesis. tissue engineered hAMC following MI provided clinically relevant benefits on cardiac function and ventricular remodeling.tissue engineered hAMC following MI provided clinically relevant benefits on cardiac function and ventricular remodeling.
