REVIEW
Matthew I Jones, Shakeel A Qureshi
Surgical repair of tetralogy of Fallot (ToF) in childhood is associated with generally good outcomes, and almost all children can be expected to survive until adulthood. However, significant pulmonary regurgitation leading to progressive right ventricular dilatation is common in teenagers or young adults because of the nature of the surgical intervention. In patients whose repair included placement of a right ventricle to pulmonary artery conduit, it has been possible to place a stented valve within the conduit to treat this...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been used as a bridge to cardiac recovery in patients following a major cardiac event. There is a lack of literature surrounding prolonged use of eptifibatide and optimal dosing during ECMO. This case report describes our experience with extended durations and standard dosing of eptifibatide in the setting of ECMO. CASE: A 40-year-old male with a history of Marfan's syndrome, aortic root and ascending aortic aneurysm status post a modified Bentall with a St...

BACKGROUND: Although balloon sizing has been found to be useful during transcatheter aortic valve implantation (TAVI), its effectiveness in patients with bicuspid aortic valve (BiAV) remains unknown. METHODS: Patients who underwent balloon sizing were retrospectively identified. The study comprised 67 patients (61.2% with BiAV). Preprocedural hypothetical transcatheter heart valve (THV) sizing was based on multislice computed tomography (MSCT) measurements at the annulus...

A 73-year-old man with severe aortic valve stenosis successfully underwent transcatheter aortic valve replacement (TAVR) using CoreValveTM (29 mm, Medtronic Inc., Minneapolis, MN, USA). Four years after the TAVR, he was hospitalized due to anterior ST-segment elevation myocardial infarction. Despite the need for prompt restoration of coronary flow in the infarct-related artery, the implanted CoreValveTM profoundly restricted the manipulation of diagnostic catheters during the coronary angiography. In particular, (I) guidewire easily migrated into the space between CoreValveTM and aorta vessel wall; (II) the nickel-titanium frame of CoreValveTM limited the space to manipulate catheters, making difficult to advance Judkins left (JL) 4, Judkins right (JR) 4 and Amplatz left 1 into coronary cusps; and (III) selecting specific spot within frame was required for cannulation...

Experience with cardiac magnetic resonance to evaluate coronary arteries in children and young adult patients is limited. Because noninvasive imaging has advantages over coronary angiography, we compared the effectiveness of these techniques in patients who were being considered for percutaneous pulmonary valve implantation. We retrospectively reviewed the cases of 26 patients (mean age, 12.53 ± 4.85 yr; range, 5-25 yr), all of whom had previous right ventricular-to-pulmonary artery homografts. We studied T2-prepared whole-heart images for coronary anatomy, velocity-encoded cine images for ventricular morphology, and function- and time-resolved magnetic resonance angiographic findings...

Coronary ostial stenosis is a rare but potentially life-threatening complication that occurs in 1%-5% of patients who undergo surgical aortic valve replacement (SAVR). Symptoms typically appear within the first 6 months and almost always within a year after SAVR. We report an unusually delayed presentation of non-ST segment elevation myocardial infarction due to coronary ostial stenosis 22 months after SAVR. A 71-year-old woman underwent uncomplicated SAVR with a bioprosthetic valve in August 2015 for severe aortic stenosis...

Transcatheter aortic valve replacement (TAVR) is a safe and effective treatment option for patients deemed at high and intermediate risk for surgical aortic valve replacement. Similar to surgical aortic valves (SAVs), transcatheter aortic valves (TAVs) undergo calcification and mechanical wear over time. However, to date, there have been limited publications on the long-term durability of TAV devices. To assess longevity and mechanical strength of TAVs in comparison to surgical bioprosthetic valves, three-dimensional deformation analysis and strain measurement of the leaflets become an inevitable part of the evaluation...

OBJECTIVES: Bioprostheses with pericardial leaflets mounted externally on the stent pose a high risk for valve-in-valve (ViV) procedures. This study analyzed the efficacy and safety of ViV procedures for treating structural valve deterioration (SVD) in Mitroflow bioprostheses. METHODS: Between January 2012 and August 2017, 11 patients (mean age 80.3 ± 5.6 years) were treated for SVD of Mitroflow bioprostheses with transcatheter ViV procedures (six transapical [TA] and five transfemoral [TF]) using balloon expandable bioprostheses...

Total aortic arch replacement using the frozen elephant trunk (FET) procedure has widely spread all over the world with more sophisticated devices. However, spinal cord injury is one of the most important complications, which limits the use of FET. In our hospital, 80 patients treated with FET had no spinal cord injury. There are three key points to avoid spinal cord injury, (1) The distal end of stent graft should be positioned up to the eighth thoracic vertebrae level; (2) the time for selective left subclavian artery perfusion and distal body circulatory arrest should be shortened within 60 min; and (3) mean blood pressure should be maintained above 70 mmHg...

Background: Residual false channel is common after repair of type A acute aortic dissection (TAAAD). Starting from our recent series of TAAAD patients we carried out a retrospective analysis, regarding the failure of primary exclusion at the time of the initial operation. We classified the location of the principal entry tears perfusing the residual false channel. The proposed technique represents our attempt to correct the mechanism of false channel perfusion during primary repair. We describe a new technique designed to address some limitations of standard hemiarch aortic replacement...

BACKGROUND: Electrophysiologic (EP) and structural interventions in adult congenital heart disease (ACHD) are typically completed during separate hospital encounters. With planning/coordination, these cases can be combined. OBJECTIVES: We hypothesized that this integrated approach would yield patient and health system benefits. METHODS: Consecutive ACHD patients undergoing combined interventions were matched to controls with identical but separate procedures...

An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled...

Mitroflow aortic prosthesis dysfunction in case of complex vascular disease is considered a challenging scenario. Because of the high risk for surgical reoperation and the presence of chronic aortic dissection originated from a calcified Kommerel diverticulum, we considered to perform a transapical valve-in-valve transcatheter aortic valve implantation (TAVI) procedure. Myocardial ischemia is a dreadful complication reported in valve-in-valve TAVI procedures, mainly in patients with degenerated Mitroflow aortic bioprostheses...

Tricuspid regurgitation (TR) presents as either primary valve pathology or secondary to pulmonary or left-sided heart disease. Severe TR portends a worse prognosis independent of age, right ventricular size and function, severe left ventricular dysfunction, and increased pulmonary arterial pressures. Surgical treatment for TR has mostly been limited to patients undergoing mitral valve repair since those at high surgical risk are not candidates for traditional TR surgery. For these patients, minimally invasive techniques could be of great benefit, yet these techniques have been slow to develop because of the various anatomic and physiological aspects of the tricuspid valve apparatus...

Papillary muscle rupture is a rare complication after myocardial infarction. Almost all cases occur in the papillary muscle of the mitral valve. The development of tricuspid regurgitation after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare. We present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous coronary intervention to the right coronary artery involving a stent. We performed tricuspid valve repair with a reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve...

We present two cases of severe aortic coarctation detected in adulthood and who underwent successful relief by transcatheter stent deployment using a new covered stent, Optimus® stent (AndraTec GmbH Koblenz, Germany). One patient is a 46-year old female with resistant arterial hypertension, in whom coarctation was suspected on a follow-up transthoracic echocardiogram for bicuspid aortic valve disease and subsequently confirmed on magnetic resonance imaging. The second patient is a 68-year old male whose coarctation was diagnosed incidentally at coronary angiography being performed as part of the preoperative work-up for severe aortic stenosis...

BACKGROUND: Patients with congenital cardiovascular disease involving the right ventricular outflow tract and with prosthetic valves in the heart are at high risk for developing infective endocarditis (IE). Recently, there has been concern about relatively high rates of IE after percutaneous pulmonary valve implantation (PPVI). Although there are factors specific to percutaneous valves that could plausibly contribute to the risk of IE, including procedural steps prior to implantation such as crimping the valved stent or mechanical forces during dilation, little is known about actual risk factors for this complication...
