An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function...

BACKGROUND: In high-risk patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) diabetes mellitus (DM) is a common comorbidity. It is known to increase the risk of arteriosclerosis and adversely affect morbidity, mortality for all types of cardiovascular disease, and post-procedural outcome after percutaneous and surgical procedures. Moreover, DM is known to facilitate the genesis of renal failure (RF). Pre-existing RF seems to increase the rate of acute kidney injury (AKI), which is a powerful short- and midterm predictor of mortality in patients undergoing TAVR...

We aimed to evaluate the safety and feasibility of PCI (percutaneous coronary intervention) for coronary artery disease (CAD) in patients undergoing transcatheter aortic valve replacement (TAVR) by performing a meta-analysis. A systemic search of the database was performed. Studies were included comparing TAVR versus TAVR with PCI for significant CAD in patients undergoing TAVR for severe aortic stenosis. The primary outcome was 30 day mortality and secondary outcomes were myocardial infarction, stroke, life threatening bleeding, major access site vascular complications and renal failure...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...

AIM: Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR). METHODS: Patients with severe symptomatic MS, who were referred to our echocardiographic laboratory for a diagnostic examination before cardiac surgery or PTMC from October of 2014 to October of 2015, were included in the study. RESULT: The peak systolic global LA strain improved post-PTMC (P < 0...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

Paravalvular leak (PVL) following aortic valve implantation is a rare complication but may cause potentially serious consequences. It occurs in 2%-10% of surgical aortic valve replacements and 7%-17% of surgical mitral valve replacements. Transcatheter valve replacement data show that significant PVL occurs in 6%-8% of cases. The management of significant PVL has traditionally involved repeat surgical repair. However, many of these patients are considered too high risk to undergo a repeat surgical procedure; hence, a percutaneous transcatheter approach has often been utilized to treat these patients...

BACKGROUND: The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. AIM: To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. METHODS: From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged<18 years), and were followed for echocardiographic homograft stenosis (peak gradient>36mmHg) and surgical or percutaneous homograft reintervention...

Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk. The rapid technologic advances and the recent improvement of clinical outcomes with TAVI have made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept (Walther T, Simon P, Dewey T, et al. Transapical minimally invasive aortic valve implantation: multicenter experience...

A 59-year-old male with a history of mitral valve replacement several years previously was admitted to the authors' institution with symptoms of advanced heart failure. Echocardiography showed a severe paravalvular dehiscence and surgery was discouraged due to high perioperative risk. A first transcatheter leak closure was unsuccessful despite the correct deployment of various occluding devices. A second percutaneous attempt was carried out with implantation of three Amplatzer Vascular Plug® III devices (five occluders were positioned in total within the oblong defect), leading to a mild residual leakage...

The role of percutaneous balloon aortic valvuloplasty (BAV) in the management of severe symptomatic aortic stenosis has come under the spotlight following the development of the transcatheter aortic valve implantation (TAVI) technique. Previous indications for BAV were limited to symptom palliation and as a bridge to definitive therapy for patients undergoing conventional surgical aortic valve replacement (AVR). In the TAVI era, BAV may also be undertaken to assess the 'therapeutic response' of a reduction in aortic gradient in borderline patients often with multiple comorbidities, to assess symptomatic improvement prior to consideration of definitive TAVI intervention...

Aortic valve replacement (AVR) remains the cornerstone of treatment for symptomatic critical aortic stenosis (AS). It is a Class I indication that symptomatic patients with critical AS undergo either surgical or transcatheter aortic valve replacement (TAVR). We present a patient with critical AS and new angina that was managed successfully with percutaneous coronary intervention (PCI) of the Right coronary artery. Physicians should consider that not all patients with critical AS and angina necessarily require AVR...

BACKGROUND: Transcaval access may enable fully percutaneous transcatheter aortic valve replacement (TAVR) without the hazards and discomfort of transthoracic (transapical or transaortic) access. OBJECTIVES: We performed a prospective, independently-adjudicated, multi-center, single-arm Investigational Device Exemption trial of transcaval access for TAVR in patients ineligible for femoral artery access and high or prohibitive risk of complications from transthoracic access...

BACKGROUND: A third percutaneous mitral balloon valvuloplasty (PMBV) may provide a means of treating symptomatic patients with re-restenosis after successful initial and second valvuloplasties, though data related to the long-term safety and efficacy of a third PMBV are lacking. The study aim was to determine the immediate and long-term clinical outcome in patients who underwent a third PMBV to treat recurrent mitral stenosis. METHODS: Among a total of 1,849 patients who underwent PMBV at the authors' institution, seven females (mean age 38...

BACKGROUND: Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating from enterochromaffin cells and secreting mainly serotonin. The diagnosis is based on clinical symptoms, hormone blood levels, radiological and nuclear imaging, and histological confirmation. However, most patients have metastases at the time of diagnosis because the clinical signs often remain unnoticed or are attributed to other abdominal conditions. In up to 50% of patients the endocardium is affected due to a hormonally active tumor profile...

Carcinoid heart disease is a rare but important cause of intrinsic right heart valve disorders leading to right heart failure. Occasionally, left-sided heart valves may also be involved. The characteristic cardiac pathological findings of carcinoid heart disease are endocardial thickening as a result of fibrous deposits on the endocardium. Echocardiographic examination and right heart catheterization are very useful for the diagnosis of the lesion. If more cardiac valves are affected, multiple valve replacement should be considered...
