In patients with atrial fibrillation, closure of the left atrial appendage (LAA) is recommended to prevent thromboembolic events, however, conventional exclusion or excision techniques have potential drawbacks such as persistent blood flow into the appendage and a residual stump. We propose a simple and easy technique for LAA closure consisting of intra-atrial excision of the LAA, which is invaginated into the left atrium (LA), and direct suture closure of the orifice from inside the LA. In this technique, complete elimination of the LAA was achieved without leaving a residual stump because the LAA was excised at the orifice and was closed at the base of the LAA.

Article Synopsis
- A four-year-old spayed female Shiba Inu was diagnosed with cor triatriatum dexter (CTD) after presenting with fluid buildup (ascites) and underwent surgery to correct the condition.
- Although the initial surgery resolved the issues, the dog experienced a recurrence of CTD and ascites seven months later, leading to the placement of a balloon-expandable stent to improve heart function.
- The second procedure successfully alleviated ascites, and the dog remained symptom-free for 18 months, highlighting that stent placement can be an effective treatment for recurrent CTD in dogs post-surgery.
Characterization of electropharmacological profile of an anti-atrial fibrillatory drug vernakalant along with potential risk toward torsade de pointes: Translational studies using isoflurane-anesthetized dogs and isolated rat aortic preparations.

We simultaneously assessed electropharmacological effects of anti-atrial fibrillatory drug vernakalant and its potential risk toward torsade de pointes. Vernakalant hydrochloride in doses of 0.3 and 3 mg/kg/10 min was intravenously administered to isoflurane-anesthetized beagle dogs without (n = 5) and with (n = 4) α-adrenoceptor blockade.

Objective: Surgical closure of the left atrial appendage (LAA) in patients with atrial fibrillation undergoing cardiac surgery can decrease the risk of stroke and thromboembolism and should therefore be considered. In minimally invasive, thoracoscopic, or robotic-assisted mitral valve surgery, however, external procedures such as clip application or epicardial resection are not feasible due to anatomic limitations and the reduced size of the access port. Internal suture closing techniques bear the risk of recurrent LAA reperfusion, so far.

Background: Treatment of benign primary cardiac tumors involves surgical resection, but reported outcomes from multi-institutional or national databases are scarce. This study examines contemporary national outcomes following surgical resection of benign primary atrial and ventricular tumors.
Methods: The 2016-2018 Nationwide Readmissions Database was queried for all patients ≥18 years with a primary diagnosis of benign neoplasm of the heart who underwent resection of the atria, ventricles, or atrial/ventricular septum.
