Background: There is a paucity of data on safety of calcium channel blockers (CCB) in patients with severe aortic stenosis (AS) and hypertension.
Methods And Results: Among 2,460 patients with severe AS and hypertension receiving antihypertensive therapy in the CURRENT AS registry-2, we compared the clinical outcomes between patients taking antihypertensive therapy with CCB (CCB group) and without CCB (no CCB group). In the entire study population, CCB was prescribed in 1,763 patients (71.
A 66-year-old man developed exertional dyspnea. The patient had undergone total arch replacement for a dissecting aortic arch aneurysm at the age of 53 and conservative treatment for myocardial infarction at the age of 60. Several imaging studies revealed a giant pseudoaneurysm that likely originated from a true ventricular aneurysm.

Spinal cord ischemic injury( SCI) continues to be the most devastating complication, that has multifactorial etiologies including embolic events and coverage of Adamkiewicz's artery (AKA). Recently, we experienced a case of Crawford III TAAA.

Among consecutive patients with severe AS between April 2018 and December 2020 in the CURRENT AS Registry-2, we identified 1714 patients who underwent aortic valve replacement (TAVI group: 1134 patients, and SAVR group: 580 patients). Patients in the TAVI group were much older (84.

Objectives: Surgical site infection in cardiovascular surgery had a great effect on postoperative outcomes. This study examined the current status of surgical site infection and postoperative outcomes used the registered data of the Japan Cardiovascular Surgery Database.
Methods: From the registry, we extracted 53,186 cases of thoracic cardiovascular surgery performed under median sternotomy in 2018.
An 80-year-old woman with essential thrombocythemia was diagnosed with severe mitral regurgitation and moderate tricuspid regurgitation. Preoperatively, she had been treated with hydroxycarbamide and low-dose aspirin since her platelet count was high( 96.2×104/μl).

We present a successful case of the management of a 46-year-old woman with an abnormal aortic valve formed by four cusps (three equal large cusps and one smaller cusp; type B according to the Hurwitz and Roberts classification) with a marked loss of coaptation that caused a severe aortic insufficiency (AI). The patient underwent an aortic valvuloplasty of the defect using the glutaraldehyde (GA)-pretreated autologous pericardium, restoring the subnormal function and competency of the aortic valve. The postoperative course was unremarkable.

Methods and results: We combined 2 independent registries, the K-TAVI Registry (a 6-center prospective registry of consecutive patients who underwent TAVI) and the CURRENT AS Registry (a large, 27-center registry of 3,815 consecutive patients with severe aortic stenosis [AS]). In the K-TAVI Registry, 338 patients underwent TAVI with SAPIEN XT balloon-expandable valves from October 2013 to January 2016, whereas in the CURRENT AS Registry 237 patients with severe AS underwent SAVR from January 2003 to December 2011.

The current roles and the future outlooks of this technology for physician-modified endovascular graft (PMEG) in patients with juxtarenal aneurysm are discussed. Fenestrations of PMEG are designed taking into account the geometry of the stent graft.
View Article and Find Full Text PDFBackground: Transcatheter aortic valve implantation (TAVI) is criticized by some as an expensive treatment in super-elder patients with limited life expectancy. However, there is a knowledge gap regarding the magnitude of clinical benefit provided by TAVI in comparison with conservative management in patients with severe aortic stenosis (AS) in real clinical practice, which would be important in the decision making for TAVI.
Methods: We combined two independent registries, namely CURRENT AS and K-TAVI registries.
A 48-year-old man underwent aortic root remodeling for a giant aneurysm of sinus of Valsalva, 98 mm in diameter, as well as a bicuspid aortic valve. The aortic valve was defined as type 0(L-R) according to Sievers classification and the aortic annulus was highly dilated up to 35 mm. Geometric height of the left and right cusps were 22 mm and 32 mm in diameter, respectively.

We included 302 patients with severe aortic stenosis who underwent TAVI using the SAPIEN XT balloon-expandable valve via transfemoral (TF; n=203, 67%) or transapical (TA; n=99, 33%) approach between October 2013 and September 2015.

Various treatment options are currently available for spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) including conservative management, anticoagulation therapy, endovascular stenting, and surgical repair. We report an experience with retrograde open mesenteric stenting for SIDSMA. A 45-year-old man presented to the emergency department with acute onset of severe abdominal and back pain.
