BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature...

Variant origin of left circumflex coronary artery (LCx) from right aortic sinus is a well-recognized coronary variation, usually without any clinical consequences. However, the variant origin and trajectory of the artery may have major implications during percutaneous coronary intervention, coronary artery surgery, aortic and mitral valve replacement procedures. We observed a variant LCx in a heart specimen belonging to 45-year-female with no history of hypertension, diabetes mellitus and coronary artery disease...

A 71-year-old man presented with New York Heart Association (NYHA) class IV heart failure. He had undergone transapical mitral valve replacement for mixed mitral stenosis and mitral regurgitation. At the 1 month follow-up, the patient reported symptom resolution. An echocardiogram revealed a low gradient and no regurgitation. Our case shows that with careful multidisciplinary evaluation, preoperative planning, and patient selection, percutaneous mitral intervention can become an alternative therapy for high-risk patients who cannot undergo conventional surgical therapy...

Transcatheter implantation of balloon expandable valves in native mitral valves (MV) has been performed in patients with severe MV annular calcification who are not good candidates for standard surgical MV replacement. Significant left ventricular outflow tract (LVOT) obstruction with hemodynamic compromise has been described as one of the potential complications of transcatheter MV replacement. Surgical rescue carries significant risk in this high-risk patient population. We describe a percutaneous technique to acutely decrease transcatheter MV replacement-induced LVOT obstruction...

BACKGROUND: Percutaneous balloon mitral valvuloplasty (PMV) is an attractive therapeutic approach in patients with mitral stenosis. The aim of this study was to assess the immediate and long-term clinical, echocardiographic and haemodynamic outcomes of PMV in patients with severe pulmonary hypertension (PAH). METHODS: Percutaneous balloon mitral valvuloplasty was performed in 157 consecutive patients; 60 patients (38,2%) had significant PAH defined as baseline pulmonary artery mean pressure (PAMP) ≥ 30mm Hg (Group 1) and 97 patients (61,8%) had PAMP ≤ 30mmHg (Group 2)...

The mitral valve is a highly complex structure, the competency and function of which relies on the harmonious action of its component parts. Minimally invasive cardiac surgery (MICS) for mitral valve repair or replacement (MVR/r) has been performed successfully with incremental improvements in techniques over the past decade. These minimally invasive procedures, while attractive to patients and referring physicians, should meet the same high bar for optimal clinical outcomes and long-term durability of valve repair as traditional sternotomy procedures...

Based on the principle of surgical edge-to-edge mitral valve repair (MVR), the MitraClip percutaneous MVR technique has emerged as a minimally invasive option for MVR. This catheter-based system has been widely demonstrated to be safe, although inferior to surgical MVR. Studies examining patients with ≥3+ mitral regurgitation (MR) show that, for all patients treated, freedom from death, surgery, or MR ≥3+ is in the 75%-80% range 1 year following MitraClip implantation. Despite its inferiority to surgical therapy, in high-risk surgical patients, data suggest that the MitraClip system can be employed safely and that it can result in symptomatic improvement in the majority of patients, while not precluding future surgical options...

OBJECTIVES: This study sought to examine the feasibility, safety, and intermediate-term outcomes in patients undergoing percutaneous transvenous transcatheter mitral valve implantation in failed bioprosthesis, ring annuloplasty, and calcific mitral stenosis. BACKGROUND: Surgical mitral valve replacement in patients with previous surgery or severe mitral annular calcification (MAC) is often associated with high or prohibitive risk. METHODS: Percutaneous transfemoral antegrade transseptal implantation of Edwards SAPIEN prosthesis (Edwards Lifesciences, Irvine, California) was performed in 48 patients with degenerated mitral bioprosthesis (n = 33), previous ring annuloplasty (n = 9), and severe MAC (n = 6)...

Paravalvular leak is a common complication after surgical mitral valve replacement. Surgically implanted prosthetic valves are complicated with paravalvular leaks in 17%.(1) Surgical closure of paravalvular leaks is the most common therapy for these defects. Percutaneous closure is an alternative to repeat surgery for a selected high-risk population. We present a case of a patient who developed severe haemolytic anaemia and secondary renal failure after partially successful percutaneous closure of paravalvular leakage of a prosthetic mitral valve...

BACKGROUND/AIMS: The best revascularization strategy for patients with both acute ST-elevation myocardial infarction (STEMI) and multivessel coronary disease (MVD) is still debatable. We aimed to compare the outcomes of multivessel revascularization (MVR) with those of culprit-only revascularization (COR). METHODS: A cohort of 215 consecutive patients who had received primary angioplasty for STEMI and MVD were divided into two groups according to whether angioplasty had been also performed for a stenotic nonculprit artery...

AIMS: Paravalvular regurgitation is an important complication of mitral valve replacement. Although surgical repair is mostly recommended, it is associated with significant morbidity. On the other hand, percutaneous closure is a less invasive alternative approach. Percutaneous approaches to treatment of paravalvular prosthetic regurgitation have emerged recently. One of them is the Occlutech Paravalvular Leak Device. The aim of this study was to evaluate early and midterm outcomes of percutaneous paravalvular leak closure utilising a novel occluder...

We report the case of a 61-year-old woman with acute decompensated heart failure secondary to acute traumatic mitral regurgitation, resulting from polymethylmethacrylate cement found in the left ventricle less than 24 hours after fluoroscopic percutaneous vertebroplasty. The patient had a history of ovarian cancer and had undergone treatment for symptomatic osteoporotic compression fractures of the vertebrae (T11, L1, and L3). The patient underwent a successful emergency open-heart operation, mitral valve replacement, closure of an atrial septal defect, and video-assisted removal of the cement foreign body from the left ventricle...

BACKGROUND: The primary goal of this study is to evaluate the immediate and long-term ef-fects of percutaneous mitral balloon valvuloplasty (PBMV) on patients with rheumatic mitral stenosis (MS) complicated with severe pulmonary hypertension (PH). METHODS: The study population consisted of 85 patients with MS complicated with severe PH (systolic pulmonary pressure > 75 mm Hg). PBMV was performed with Inoue balloon technique. Clinical and echocardiographic follow-up was scheduled at 6 months and 1 year and yearly thereafter...

The dilemma of the patient with both AS and LVOTO is now commonly encountered in clinical practice; indeed, physicians must be aware of the complex interaction and coexistent nature of both diseases, especially as both HOCM and TAVR have increased in awareness and prevalence. Importantly, the clinician must be aware of the complex interplay hemodynamically, with the two diseases confusing the TTE imaging and potentially affecting each other anatomically and clinically. There is no set guideline on how to approach this from a surgical or percutaneous approach, but we have outlined a set of recommendations which should serve the clinician and patient well...

We report a patient with class III heart failure symptoms due to mitral regurgitation (MR) subsequent to nonischemic cardiomyopathy. The patient underwent percutaneous transcatheter mitral valve repair using a single MitraClip, which reduced the MR; however it created mild-to-moderate mitral stenosis, which progressed to severe mitral stenosis. Subsequently the patient underwent mitral valve replacement surgery.
