The J-Valve system is designed specifically for trans-apical transcatheter aortic valve replacement (TAVR) and has three U-shaped graspers. With the unique structure, J-Valve is suitable for both aortic stenosis and aortic regurgitation. We used the J-Valve system for patients with aortic valve diseases and observed favorable results. From January 2018 to August 2019, 23 patients underwent trans-apical transcatheter valve replacement using the J-Valve system. High-risk patients with diseased peripheral vessels (Small diameter, heavily calcified, and tortuous arteries), pure aortic regurgitation and complex prosthetic valve-in-valve (ViV) cases were enrolled. Ten patients mainly suffered from aortic stenosis, 11 patients had pure aortic regurgitation, and two patients had a ViV aortic valve position. The average preoperative STS score and EuroSCORE II were 8.9% and 8.7%, respectively. The technique success rate was 91.3% (21/23, one patient was referred for open surgery and one patient received intraoperative valve-in-valve), and one patient died because of cardiogenic shock after the procedure (mortality 4.3%, 1/22). Selleckchem Sardomozide One patient suffered stroke postoperatively and recovered well, and no cases needed to undergo permanent pacemaker implantation. During the follow-up period, one patient died because of an acute heart attack. No moderate or severe paravalvular leakage was found. TAVR surgery with the J-valve system is effective, even when it is traumatic and requires the trans-apical route. The applicability of the J-valve system in pure aortic regurgitation patients is the advantage of this system.

Periodical follow-up computed tomography confirmed that the residual false lumen after aortic repair had gradually thrombosed over time regardless of sufficient antithrombotic therapy. We analyzed the chronological changes in the false lumen morphology, showing transient enlargement of the aortic diameter 1 year postoperatively and then reduction 3 years postoperatively. This is the first report on the fate of residual false lumen after aortic repair under continuous-flow left ventricular assist device circulation. Cannabis is the most commonly used illicit substance in the United States. As cannabis use rises in popularity and its legalization continues to expand, the scientific community must address the controversy between beneficial and adverse effects of cannabis consumption. We have performed a comprehensive literature review to study the medicinal and pathological effects of cannabis use, with emphasis on its association with cancer pathophysiology and thoracic surgery. We found evidence that cannabis products often contain carcinogenic materials, and their use is associated with development of certain head and neck cancers, but not lung cancer. Indeed several in vitro and in vivo studies have demonstrated that cannabis may have a therapeutic role in cancer given the antiproliferative effects of its active compounds such as delta-9-tetrahydrocannabinol. Cannabis-derived products have also been shown to be effective treatments for chronic pain, neuropathy, spasticity, and as anti-emetics. We acknowledge that additional studies are required to elucidate the long-term effects of cannabis products, and that many potential biases and limitations exist in the literature due to self-reporting and limited survey studies. Appropriate stewardship over cannabis use amongst our patient population will likely determine its full implications in te
