Introduction: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare coronary artery anomaly that carries 90% mortality in the first year of life when left untreated. The diagnosis of ALCAPA is rare in adulthood, and it includes a broad spectrum of clinical manifestations, including sudden cardiac death (SCD). Case report: We report a rare case of resuscitated sudden cardiac arrest in a 55-year-old female, who was diagnosed with ALCAPA and underwent successful surgical correction and implantable cardioverter defibrillator (ICD) implantation for secondary prevention. Discussion: ALCAPA diagnosis is not confined to childhood, and it represents a rare cause of life-threatening arrhythmias and SCD in the adult population. Surgical correction is recommended, regardless of age, presence of symptoms or inducible myocardial ischemia. Multimodality imaging is crucial for diagnosis, management planning and follow up. Assessment of the risk of recurrent ventricular arrhythmias, despite full revascularization, should be performed in all adults with ALCAPA. Myocardial scar detected via late gadolinium enhancement represents a potential irreversible substrate for ventricular arrhythmias, and it provides additional information to evaluate indication of an ICD for secondary prevention.

AngioVac is used for the percutaneous removal of vegetations and for debulking of large vegetations in patients who are not surgical candidates.This study aims to identify the demographics, echocardiographic features, indications, improvement of the tricuspid valve regurgitation, and survival outcomes of patients who have undergone AngioVac vegetectomy reported in the literature. A systematic review was performed to identify articles reporting suction thromectomy or vegetation removal using the AngioVac system for RSIE (right sided infective endocarditis). Survival on discharge was our primary outcome. Additionally, we evaluated indications for suction thrombectomy and TR improvement. Categorical variables were expressed as percentages and ratios. A total of 49 studies were identified. The most common risk factor was intravenous drug abuse seen in 45% (20/49) and cardiovascular implantable electronic device (CIED) in 45% (20/49). Circulatory shock was seen in 35% of patients. The causative organism was gram positive cocci (86%). Moderate to severe TR was present in 74% of cases with documented echocardiograms. Indications for AngioVac were poor surgical candidacy (81%) or to reduce septic emboli risk (19%). Survival at discharge was 93%. TR improvement was reported only in 16% cases and remained unchanged/worsened in 84%. AngioVac procedure is an alternative treatment for critically ill patients who cannot undergo surgery. To understand the survival, safety and candidacy of patients undergoing this procedure, further randomized control studies and literature reviews are needed. The improvement or worsening of tricuspid regurgitation in patients with TR valve involvement is another factor to be investigated.

Surgical aortic valve replacement (SAVR) is the mainstay treatment for aortic valve diseases in patients with low surgical risk. Trans aortic valve replacement (TAVR) has also grown over the past few years, although limited durability data is available. Atrioventricular conduction abnormalities (AVCA) are known complications in the immediate period post-TAVR and SAVR. There are no case reports regarding the development of the delayed onset AVCA years after SAVR. In this case report, we present a male patient who developed a complete heart block six years after SAVR, following which he got the permanent pacemaker implantation (PPMI).

Background: Cardiovascular magnetic resonance (CMR) can noninvasively identify myocardial fibrosis using extracellular volume (ECV) mapping. In patients with elevated ECV, and without hypertrophic cardiomyopathy (HCM) or cardiac amyloidosis, the prognostic significant of mild-to-moderate left ventricular hypertrophy (LVH) has not been well established. Purpose: To determine if the presence of mild to moderate LVH has an impact on major adverse cardiovascular outcomes (MACE) in patients with elevated ECV without HCM or cardiac amyloidosis. Methods: This was a retrospective cohort study assessing a group of patients referred for CMR between July 2019 and January 2023 to Mount Sinai Morningside. Patients with ECV>30% and left ventricular wall thickness <1.6 cm (to exclude patients with the possible diagnosis of HCM or cardiac amyloidosis) were considered for inclusion. Those with an established diagnosis of HCM or cardiac amyloidosis were also excluded. The LVH group comprised of patients with mild-to-moderate LVH, defined as a maximum wall thickness of 1.2-1.5 cm. The control group included patients without LVH (wall thickness <1.2 cm). Patients were further stratified by ECV, using the median value for our sample, as "high ECV" (≥35%) or "low ECV" (<35%). The outcome of interest was time-to-first MACE (all-cause death, or incident acute coronary syndrome, acute heart failure, or arrhythmia). Time-to-first MACE within 1 year was compared among groups using unadjusted Kaplan-Meier curves. Additional Cox regression analyses were performed to adjust for significant univariate analysis, including hypertension, hyperlipidemia, diabetes mellitus, use of beta-blocker, use of diuretic, and category of glomerular filtration rate. The results are presented as hazard ratios and 95% confidence intervals. All analyses were performed in SAS Enterprise using α<0.05. Results: Out of the cohort, we identified 186 patients that met our selection criteria. The mean age was 61.1 ± 15.5 years, and 58.1% of patients were female. The median follow-up was 175 days in the control group and 115 days in the LVH group. There were 61 MACE (32.8%) in our sample. After adjusting for covariates, mild-to-moderate LVH was associated with 2.2 times the risk of MACE (95%CI 1.3 to 3.8; p=0.0047) at 1 year, compared to patients without LVH. A higher ECV (≥35%) was not significantly associated with worse outcomes within each study arm (p=0.3450). Kaplan Meier survival curves for patients with and without LVH are shown in Figure 1 (p=0.0002). Conclusions: In patients with evidence of elevated ECV without underlying cardiac amyloidosis or hypertrophic cardiomyopathy, mild-to-moderate LVH is associated with 2.2 times the risk of MACE compared to normal left ventricular wall thickness.Figure 1
