We report successful thoracic endovascular repair of a pseudoaneurysm rupture in the ascending aorta using infrarenal endovascular devices after an aortic valve replacement. Complete exclusion of the pseudoaneurysm was achieved with no endoleak or postoperative complications. Despite limitations of the current technology, this endovascular technique was a relatively less invasive, feasible lifesaving surgical option for the repair of a pseudoaneurysm of the ascending aorta with a diameter ≤32 mm.

Rapid-deployment valves could potentially reduce cross-clamping time and cardiopulmonary bypass time in complex combined procedures and facilitate minimally invasive surgery. This propensity-matched study compared clinical and echographic outcomes between patients undergoing rapid-deployment aortic valve replacement (RDAVR) compared with stented biological aortic valve replacement (SAVR), with or without concomitant procedures. Between 2012 and 2015, 61 consecutive patients (age 70 ± 7 years, European System for Cardiac Operative Risk Evaluation [EuroSCORE] II 2...

OBJECTIVES: Asians are smaller than Europeans and North Americans, but aortic valve replacement (AVR) in small patients has not been examined. We aimed to compare short- and mid-term outcomes of AVR between small and non-small patients. METHODS: We retrospectively divided 173 patients who underwent AVR into small (S, n = 95) and non-small (NS, n = 78) groups according to body surface area (≤1.6 in men, ≤1.5 in women) and analyzed differences in baseline characteristics, procedural and post-procedural variables, and survival...

INTRODUCTION: Liposarcoma of the heart and stomach is rare. PRESENTAION OF CASE: We report a case of liposarcoma in both organs with dedifferentiated histology. A patient was referred to our hospital with anorexia and weight loss. Upper gastrointestinal tract endoscopy revealed 5-10-mm elevated lesions, and echocardiography and computed tomography showed tumorous lesions in the left atrium. Tumor resection and mitral valve replacement were performed, and biopsy was performed for the gastric tumor...

Valvular heart disease is currently treated with mechanical valves, which benefit from longevity, but are burdened by chronic anticoagulation therapy, or with bioprosthetic valves, which have reduced thromboembolic risk, but limited durability. Tissue engineered heart valves have been proposed to resolve these issues by implanting a scaffold that is replaced by endogenous growth, leaving autologous, functional leaflets that would putatively eliminate the need for anticoagulation and avoid calcification. Despite the diversity in fabrication strategies and encouraging results in large animal models, control over engineered valve structure-function remains at best partial...

Transcatheter aortic valve implantation (TAVI) is the method of choice in patients with high risk or contraindications for conventional aortic valve replacement. However, it is not well understood which parameters predict the overall cardiac function post- procedurally. MicroRNAs (miRNA/ miR) are small non-coding RNA molecules that repress gene expression by different mechanisms and can also be detected in the blood. Recent studies have shown that miRNAs detected in the blood may serve as sensitive and specific biomarkers in various diseases, therefore we examined the levels of different microRNAs in the serum of patients undergoing TAVI...

The objective of this report was to directly compare, by means of a systematic review and meta-analysis, redo surgical aortic valve replacement (re-sAVR) with valve-in-valve transcatheter aortic valve implantation (ViV TAVI) for patients with failed degenerated aortic bioprostheses. Multiple databases were screened for all available reports comparing ViV TAVI with re-sAVR in patients with failing degenerated aortic bioprostheses. The primary outcome was all-cause mortality determined from the longest available survival data...

Background: Transcatheter aortic valve replacement (TAVR) has been shown safe and feasible in patients with bicuspid aortic valve (BAV) morphology. Evaluation of inter-ethnic differences in valve morphology and function and aortic root dimensions in patients with BAV is important for the worldwide spread of this therapy in this subgroup of patients. Comparisons between large European and Asian cohorts of patients with BAV have not been performed, and potential differences between populations may have important implications for TAVR...

OBJECTIVES: Downsizing a homograft (HG) through bicuspidalization has been used for more than 2 decades to overcome the shortage of small-sized conduits for reconstruction of the right ventricular outflow tract (RVOT) in young children. Our goal was to investigate the durability of bicuspidalized HGs compared with other small HGs. METHODS: A retrospective analysis of 93 conduits ≤20 mm, implanted over 23 years, was performed. The end-points were survival, structural valve degeneration and conduit replacement...

Conduction abnormalities after cardiac surgery are common as is spontaneous resolution of these abnormalities. However, 1%-3% of patients will require placement of a permanent pacemaker. Patients with preexisting conduction abnormalities, undergoing reoperation, preexisting pulmonary hypertension and undergoing mitral or aortic valve operations are at a higher risk for requiring a permanent pacemaker. We present the first case described in the literature of a patient with a preexisting left bundle branch block, and heart failure with a reduced left ventricular ejection fraction of 25% who developed complete heart block after placement of a coronary sinus catheter...
