AIMS: Mitral annular calcification (MAC) negatively influences outcomes in surgical mitral valve (MV) repair for mitral regurgitation (MR). However, there are no data on whether MAC impacts on outcomes of MitraClip percutaneous MV edge-to-edge repair. This study sought to investigate whether the presence of MAC impacts on the procedural success and durability of percutaneous transcatheter repair of MR using the MitraClip. METHODS AND RESULTS: One hundred and seventy-three patients undergoing MitraClip repair for significant MR were studied...

We present the primary report of a paediatric patient who had placement of the MitraClip device for severe functional mitral regurgitation. The patient was a 14-year-old boy with symptomatic end-stage non-compaction type cardiomyopathy secondary to a mitochondrial cytopathy. He had severe mitral regurgitation, tricuspid valve regurgitation, a severely dilated LV with apical non-compaction, severe LV dysfunction and severe pulmonary hypertension. Despite optimal medical therapy he developed progressive symptoms of congestive heart failure and he was not a candidate for an assist device or cardiac transplantation...

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...

Optimal time to perform percutaneous mitral valvuloplasty (PMV) for patients with significant mitral stenosis (MS) and atrial fibrillation (AF) remains controversial. We sought to identify prognostic factors and evaluate long-term clinical outcomes after PMV of 77 consecutive patients with MS with a mitral valve area (MVA) <1.5 cm(2). According to baseline heart rhythm, these patients were divided into sinus rhythm (SR; n = 24) and AF (n = 53) groups. The study endpoint was defined as a composite of all-cause mortality, admission for heart failure, mitral valve surgery, repeated PMV, and major cerebral vascular accident during follow-up...

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is first-line therapy for some congenital heart disease patients with right ventricular outflow tract dysfunction. The hemodynamics improvements after PPVI are well documented, but little is known about its effects on the electrophysiologic substrate. The objective of this study is to assess the short- and medium-term electrophysiologic substrate changes and elucidate postprocedure arrhythmias. METHODS AND RESULTS: A retrospective chart review of patients undergoing PPVI from May 2010 to April 2015 was performed...

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is utilized for dysfunctional right ventricular outflow tracts (RVOT) to relieve obstruction, regurgitation, and RV dysfunction. PPVI has not been reported to induce arrhythmias. This study is the first to report the incidence of ventricular tachycardia (VT) after PPVI. METHODS: This was a retrospective study of all patients who had PPVI at a single institution. All patients were admitted after PPVI for overnight telemetry monitoring...

BACKGROUND: Pulmonary insufficiency is the nexus of late morbidity and mortality after transannular patch repair of tetralogy of Fallot. This study aimed to establish the feasibility of implantation of the novel Medtronic Harmony transcatheter pulmonary valve (hTPV) and to assess its effect on pulmonary insufficiency and ventricular function in an ovine model of chronic postoperative pulmonary insufficiency. METHODS AND RESULTS: Thirteen sheep underwent baseline cardiac magnetic resonance imaging, surgical pulmonary valvectomy, and transannular patch repair...

Pseudoaneurysm formation is a rare but potentially life-threatening complication after surgical repair of congenital heart disease. We present a boy with truncus arteriosus communis 14 years after homograft placement in pulmonary position. On follow-up, he presented progressive chronic homograft degeneration. Moreover, a large pseudoaneurysm in the right ventricular outflow tract was surprisingly depicted. We opted for a two-stage interventional approach.

Progressive dyspnea and hypoxaemia in the subacute phase after transcatheter aortic valve implantation (TAVI) are uncommon and warrant immediate assessment of valve and prosthesis leaflet function to exclude thrombosis, as well as investigation for other causes related to the procedure, such as left ventricular dysfunction, pulmonary embolism, and respiratory sepsis. In this case, we report the observation of a patient presenting two weeks after TAVI with arterial hypoxaemia in an upright position, relieved by lying flat, and coupled with an intracardiac shunt detected on echocardiography in the absence of pulmonary hypertension, raising the suspicion of Platypnea-Orthodeoxia Syndrome (POS)...

BACKGROUND: Although associated with left heart pathologies, functional tricuspid regurgitation (FTR) is often left untreated during left heart surgery. Hence, owing to its degenerative character, reoperation is often needed, encompassing an impressive (25% to 35%) mortality rate. Thus transcatheter approaches to FTR are raising great interest. OBJECTIVES: The authors evaluated the post-treatment effectiveness of the edge-to-edge technique using the percutaneous mitral valve repair device in an ex vivo pulsatile model of FTR...

Carcinoid heart disease presents as right-sided heart failure attributable to the dysfunction of the tricuspid and pulmonary valves. Although surgical valve replacement is the mainstay of treatment when patients become symptomatic, it is associated with substantial perioperative mortality rates. We present a case of severe pulmonary valve stenosis secondary to carcinoid heart disease, treated successfully with percutaneous valve replacement. A 67-year-old man with severe pulmonary valve stenosis was referred to our center for pulmonary valve replacement...

We report two cases of severe mitral stenosis where percutaneous mitral commisurotomy was performed within pregnancy. The first case involves an emergency procedure for a new diagnosis of severe mitral stenosis in a woman presenting with pulmonary oedema at 27 weeks' gestation. The second case is of a woman known to have mitral stenosis who underwent a semi-elective procedure for deterioration in symptoms. This procedure is not commonly performed in the United Kingdom because of low incidence of rheumatic heart disease...

AIMS: Our aim was to report the first five cases of percutaneous implantation of the Venus P-valve® in Europe. METHODS AND RESULTS: We successfully implanted Venus P-valves in five consecutive cases in patients whose anatomy was thought to be unfavourable for currently available percutaneous valve prostheses and who had relative contraindications to surgical valve replacement. The procedures were performed at Guy's and St Thomas' NHS Foundation Trust, London, United Kingdom...

BACKGROUND: The most common reason for reintervention after a Björk modification of the Fontan procedure, in which the right ventricle (RV) is incorporated into the pulmonary circulation by connecting the right atrial (RA) appendage to the RV directly or with an extra-anatomic graft, is obstruction or regurgitation of the RA-RV connection. Transcatheter implantation of a valved stent is an appealing option for the treatment of RA-RV conduit dysfunction in these patients. In the present study, we assessed early and intermediate results after transcatheter valve implantation within an obstructed or regurgitant RA-RV modified Fontan pathway...

We report a case of a 54-year-old patient with a T3c renal mass with intracardiac extension of the thrombus to the level of the pulmonary valve. The patient was not a candidate for cardiopulmonary bypass due to recent pulmonary embolism. Under transesophageal echocardiogram guidance, the intracardiac thrombus was removed percutaneously via transvenous mechanical thrombectomy. The patient was effectively downstaged to T3b and underwent successful radical nephrectomy and inferior vena cava thrombectomy without the use of cardiopulmonary bypass...

OBJECTIVE: To evaluate the rate of pulmonary stenosis and functional pulmonary atresia (PS/PA) in recipient twins prior to fetal surgery for twin-twin transfusion syndrome (TTTS) and their pre- and postnatal outcomes. METHODS: We carried out a prospective study including 260 cases of TTTS. Echocardiography was performed before laser surgery to detect the presence of PS/PA. The outcomes of recipients with and without PS/PA were compared. The need of postnatal cardiac interventions and the survival rate at 6 months of age were also evaluated...

BACKGROUND: Although percutaneous Melody valve implant has become an accepted alternative to surgical pulmonary valve replacement in patients with congenital heart disease (CHD), the benefit regarding frequency and severity of arrhythmias remains undefined. OBJECTIVE: This study evaluated the impact of Melody valve implant on the type and frequency of arrhythmias during cardiopulmonary exercise testing (CPET) and subsequent clinical outcome. METHODS: As part of the phase I Melody valve clinical trial, 136 patients with CHD underwent prospective serial evaluation including CPET prior to, 6 months after, and annually for 5 years...
