RESUMEN
Background: The effectiveness of cerebral embolic protection devices (CEPD) in mitigating stroke after transcatheter aortic valve implantation (TAVI) remains uncertain, and therefore CEPD may be utilized differently across US hospitals. This study aims to characterize the hospital-level pattern of CEPD use during TAVI in the US and its association with outcomes. Methods: Patients treated with nontransapical TAVI in the 2019 Nationwide Readmissions Database were included. Hospitals were categorized as CEPD non-users and CEPD users. The following outcomes were compared: the composite of in-hospital stroke or transient ischemic attack (TIA), in-hospital ischemic stroke, death, and cost of hospitalization. Logistic regression models were used for risk adjustment of clinical outcomes. Results: Of 41,822 TAVI encounters, CEPD was used in 10.6% (n = 4422). Out of 392 hospitals, 65.8% were CEPD non-user hospitals and 34.2% were CEPD users. No difference was observed between CEPD non-users and CEPD users in the risk of in-hospital stroke or TIA (adjusted odds ratio (OR) = 0.99 [0.86-1.15]), ischemic stroke (adjusted OR = 1.00 [0.85-1.18]), or in-hospital death (adjusted OR = 0.86 [0.71-1.03]). The cost of hospitalization was lower in CEPD non-users. Conclusions: Two-thirds of hospitals in the US do not use CEPD for TAVI, and no significant difference was observed in neurologic outcomes among patients treated at CEPD non-user and CEPD user hospitals.
RESUMEN
OBJECTIVE: Operative techniques for minimally invasive cardiac surgery (MICS) have evolved dramatically over the past decade to include a wide demographic of patients. Mastering a variety of cannulation techniques is of paramount importance in performing a safe perfusion strategy and operation. Our aim is to describe cannulation strategies utilized in various MICS procedures. METHODS: We review numerous cannulation strategies and their application in different minimally invasive procedures. RESULTS: Cannulation strategies will vary depending on the MICS procedure and other anatomical variations and obstacles. Utilizing the appropriate cannulation strategy will allow for a safe and effective operation. CONCLUSIONS: Mastering the art of cannulation will provide surgeons with a toolbox to choose from when performing MICS in a wide variety of procedures.

The left atrial appendage (LAA) has been identified as a site of thrombus formation in the heart and as a source of embolism in patients with atrial fibrillation, leading to stroke. Studies suggest that LAA closure may reduce the risk for stroke and the need for anticoagulation; conversely, incomplete closure can increase the stroke risk almost 12-fold. Because open heart surgery is associated with increased risk for subsequent stroke, surgeons generally prefer to close the LAA during heart surgery, as recommended in current atrial fibrillation management guidelines. Building on trends toward minimally invasive approaches in cardiac surgery, we developed a simple, unique, and reproducible method for complete LAA closure during mitral valve surgery that has proven to be safe and efficacious: Our first three patients remained completely free from stroke and minor neurological manifestations 27 months after surgery.
