RESUMO

Embolised needles causing injury to the right heart and cardiac tamponade has been reported before in intravenous drug users, but to our knowledge, this is the first reported case of a needle migrating via the pulmonary arterial system to cause perforation of the left ventricle. Appropriate utilisation of imaging modalities such as plain X-ray and point-of-care focused cardiac ultrasound can be vital and life-saving in the emergency setting, and the value of gated multidetector CT as a powerful tool for imaging moving structures is highlighted.

RESUMO

Takayasu's arteritis (TA) is a vasculitis with a predilection for young women. Left ventricular pseudoaneurysm (PSA) in TA is a rare phenomenon. We report a 36 years old Filipina who presented with heart failure symptoms. Years prior, she had a recurrent fever, headache, myalgia and left arm claudication. On workup, a 2D echo revealed a left ventricular PSA with mural thrombus and moderate mitral regurgitation. Cardiac MRI further characterised the PSA with a sac diameter of 8×7.5×8.4 cm (CC×T×AP). Carotid Duplex Scan revealed total occlusion of the mid to distal right common carotid artery and left subclavian artery. She was started on immunosuppresants and guideline-directed medical therapy (GDMT) for heart failure and subsequently underwent successful endoventricular patch closure and mitral valve repair. This case highlights the importance of actively searching for cardiac complications of TA which although very rare, can dominate the clinical picture and may carry a dismal prognosis if left untreated.

RESUMO

BACKGROUND: Myxoma is an uncommon disease and its symptoms vary greatly depending on size, location and mobility. Right-sided myxoma, especially right ventricular myxoma, is much rarer, and the symptoms are alien and uncharacteristic. The lack of understandings poses challenges to prompt diagnosis and timely treatment. CASE PRESENTATION: A 44-year-old female patient was diagnosed with giant right ventricular tumor. Right heart failure and systemic congestion caused by right ventricular outflow tract obstruction were observed on this case. Surgery was performed to excise the mass which was measured at 9.5 * 5.0 cm and confirmed as myxoma pathologically. CONCLUSIONS: Right-side myxoma is easy to be unnoticed due to its low incident rate and atypical symptoms. Delay in surgical intervention might cause unrecoverable complications. More comprehensive understanding of the symptoms is expected to help improving the diagnose and treat of right-sided myxoma.

RESUMO

We report a case of Bentall and redo-Konno operation. A 39-year-old male with surgical history of Konno operation presented with hemolytic anemia and heart failure. Further evaluations revealed aortic paraprosthetic leak with moderate regurgitation, moderate biventricular outflow tract obstruction, and aortic root aneurysm. During the operation, the old Konno septoplasty patch with organized thrombus and the severely calcified right ventricular patch were replaced, and the aortic root was replaced with a larger mechanical valve in a Valsalva graft. Postoperative images showed appropriately reconstructed biventricular outflow tracts. The Bentall operation with redo-Konno was an excellent option in this situation.

RESUMO

Cardiac metastasis from renal cell carcinoma (RCC) is relatively rare. It generally initiates from the right atrium with or without involvement of the inferior vena cava (IVC). Here, we report a case of metastasis of isolated clear cell RCC to the left ventricular( LV) papillary muscle. An 84-year-old male who had undergone renal resection due to RCC 19 years before, presented to our hospital with suspected LV tumor by echocardiography. The tumor was located near the posterior papillary muscle, with a size of 15×12 mm. The patient underwent resection of the LV tumor. Pathologically, the tumor was diagnosed as clear cell RCC. The postoperative course was stable, and he did not require any chemotherapy. Although there is no definite evidence of the mechanisms of metastasis, the tumor was supposed to metastasize lymphogeneously.

RESUMO

We present the clinical case of a 60-year-old woman complained of dyspnea on exertion. Echocardiogram showed a giant mass in the right ventricle (RV) with obstruction to the outflow tract. Thorax computed tomography confirmed a mass of greater than 60 mm infiltrating RV and causing severe stenosis in the pulmonary artery, with severe pericardial effusion. Cardiac surgery was performed for tumor resection and pulmonary root replacement with a biological valved conduit. Histological analysis diagnosed a poorly differentiated large-cell neuroendocrine carcinoma. The patient had no immediate postoperative complications and has completed radiotherapy at a 9-month follow-up.

RESUMO

INTRODUCTION: Various valve repair techniques have been described for prevention of pulmonary insufficiency (PI) during right ventricular outflow tract (RVOT) reconstruction with transannular patch. Herein, we present the early results of an alternative technique of neopulmonary valve reconstruction using right atrial appendage (RAA) tissue. METHODS: Between October 2019 and December 2019, 12 patients with tetralogy of fallot (TOF) (n = 10), TOF-absent pulmonary valve (n = 1) and intact ventricular septum-pulmonary atresia (n = 1) underwent RVOT reconstruction with neopulmonary valve that was created using RAA tissue. Median age and weight of patients were 9.9 months (5 months-14 years) and 9.8 kg (6.2-47), respectively. RESULTS: No mortality or major events developed. Postoperative echocardiography revealed none/trace PI in 11 patients and mild PI in 1 patient. Median right ventricle/left ventricle ratio was 0.46 (0.35-0.65) and RVOT gradient was 20 mm Hg (0-30). Median cardiopulmonary bypass and aortic clamping times were 121 minutes (81-178) and 94 minutes (59-138), respectively. Operative times revealed statistically significant learning curve pattern in terms of cardiopulmonary bypass (r2 = .568; P = .005) and aortic clamping times (r2 = .635; P = .002). Median ventilation time, intensive care unit stay, and the length of hospital stay were 6 hours (2-48), 1 days (1-5), and 7 days (4-10), respectively. Longer perfusion time was not correlated with postoperative times. At median 6 months, echocardiography showed none/trivial PI in 11 patients and mild PI in one patient. CONCLUSION: Early results showed that neopulmonary valve reconstruction using the RAA tissue may provide a reasonable alternative for RVOT reconstruction with transannular patch. But long-term results are needed.

RESUMO

BACKGROUND: Phrenic nerve injury is a known cause of morbidity after single ventricle palliation. Previous studies have shown that hemidiaphragm plication improves short-term outcomes. The effect of plication on the outcomes of subsequent stages of single ventricle palliation is unknown. METHODS: From 1997 to 2015, 1146 patients underwent surgical management of single ventricle physiology at our institution. We reviewed the records of 30 patients who had undergone diaphragm plication for phrenic nerve injury before Fontan completion. Each patient was compared with 2 propensity-matched controls identified from patients who underwent the Glenn or Fontan procedure during the same period without diaphragm plication. Propensity matching was achieved for each test subject using the nearest neighbor algorithm. Data are presented as the median and quartiles or numbers and percentages. RESULTS: The cohort included 18 boys (60%). Of the 30 patients, 19 (63%) had undergone plication after first-stage palliation. Of these, 13 have undergone completion Fontan, 5 were awaiting Fontan at the last follow-up, and 1 had died. An additional 11 patients had undergone plication after Glenn and proceeded to Fontan completion. Thus, 24 patients with diaphragm plication have undergone Fontan completion. No difference was found in pulmonary pressure or resistance between the plicated patients and their propensity-matched controls. Both groups had comparable chest tube output and hospital lengths of stay. Equal proportions of patients in both groups required pulmonary vasodilator therapy and/or supplemental oxygen at hospital discharge. CONCLUSIONS: Prior diaphragm plication does not adversely affect Fontan completion in children with single ventricle physiology. The hospital course during subsequent stages of palliation for plicated patients was no different than that of matched controls.

RESUMO

A 59-year-old man with acute mitral regurgitation due to papillary muscle rupture after myocardial infarction was admitted to our hospital. He underwent emergent mitral valve replacement with a mechanical valve by median sternotomy. Although postoperative echocardiography showed no sign of a ventricular aneurysm, echocardiography performed 5 weeks after the surgery showed enlarging left ventricular pseudoaneurysm of the inferior to the posterior cardiac wall. He underwent dacron patch closure of the orifice by fifth intercostal left thoracotomy. The postoperative course was uneventful and he was discharged on postoperative day 10. The patient was successfully treated for two life-threatening complications occurring subsequently after myocardial infarction.

RESUMO

Rupture of a congenital left ventricular diverticulum (CLVD), a rare anatomical anomaly, is a catastrophic event, with potential fatal consequences. Repair techniques documented in the literature include primary closure and single patch closure. We describe a case of a 57-year-old woman with symptomatic anterolateral CLVD. Our approach involves a linear incision through the epicardial surface of the diverticulum with exclusion of the cavity, and restoration of normal ventricular geometry via a two-patch technique.

RESUMO

BACKGROUND: The right ventricle (RV) often fails when functioning as the systemic ventricle, but the cause is not understood. We tested the hypothesis that myofiber organization is abnormal in the failing systemic right ventricle. METHODS: We used diffusion-weighted cardiovascular magnetic resonance imaging to examine 3 failing hearts explanted from young patients with a systemic RV and one structurally normal heart with postnatally acquired RV hypertrophy for comparison. Diffusion compartment imaging was computed to separate the free diffusive component representing free water from an anisotropic component characterizing the orientation and diffusion characteristics of myofibers. The orientation of each anisotropic compartment was displayed in glyph format and used for qualitative description of myofibers and for construction of tractograms. The helix angle was calculated across the ventricular walls in 5 locations and displayed graphically. Scalar parameters (fractional anisotropy and mean diffusivity) were compared among specimens. RESULTS: The hypertrophied systemic RV has an inner layer, comprising about 2/3 of the wall, composed of hypertrophied trabeculae and an epicardial layer of circumferential myofibers. Myofibers within smaller trabeculae are aligned and organized with parallel fibers while larger, composite bundles show marked disarray, largely between component trabeculae. We observed a narrow range of helix angles in the outer, compact part of the wall consistent with aligned, approximately circumferential fibers. However, there was marked variation of helix angle in the inner, trabecular part of the wall consistent with marked variation in fiber orientation. The apical whorl was disrupted or incomplete and we observed myocardial whorls or vortices at other locations. Fractional anisotropy was lower in abnormal hearts while mean diffusivity was more variable, being higher in 2 but lower in 1 heart, compared to the structurally normal heart. CONCLUSIONS: Myofiber organization is abnormal in the failing systemic RV and might be an important substrate for heart failure and arrhythmia. It is unclear if myofiber disorganization is due to hemodynamic factors, developmental problems, or both.

RESUMO

BACKGROUND: Despite improved survival and morbidity after durable left ventricular assist device (dLVAD), outcomes for cardiogenic shock patients are suboptimal. Temporary mechanical circulatory support (tMCS) can permit optimization before dLVAD. Excellent outcomes have been observed using minimally-invasive dLVAD implantation. However, some feel tMCS contraindicates this approach. To evaluate whether left thoracotomy/hemisternotomy (LTHS) dLVAD placement is safe in this setting, we compared patients who did and did not require tMCS. METHODS: Outcomes for patients receiving dLVADs via LTHS were compared among those bridged with extracorporeal membrane oxygenation (ECMO), intra-aortic balloon pump (IABP), or no tMCS. We evaluated demographics, comorbidities, laboratory and hemodynamic data, and intraoperative and postoperative outcomes. RESULTS: Eighty-three patients underwent LTHS dLVAD placement. Fifty did not require tMCS, while 22 (26%) required IABP, and 11 (13%) ECMO. Non-tMCS patients were primarily Intermacs 3 (56%), while IABP recipients were mainly Intermacs 2 (45%). All patients with ECMO were Intermacs 1. Patients with tMCS had worse end-organ function. Operative outcomes were similar except more concomitant procedures and red-cell transfusions in patients with ECMO. Intensive care unit and hospital length of stay and inotrope duration were also similar. There were no differences in bleeding, stroke, and infection rates. Three- and 12-month survival were: no tMCS: 94%, 86%; IABP: 100%, 88%; and ECMO: 81%, 81% (P = .45). CONCLUSIONS: Patients with cardiogenic shock can safely undergo LTHS dLVAD implantation after stabilization with ECMO or IABP. Outcomes and complications in these patients were comparable to a less severely ill cohort without tMCS.

RESUMO

Left ventricular aneurysm is a late mechanical complication of untreated acute myocardial infarction. It has become relatively rare since the development of percutaneous cardiac intervention.  Most aneurysms are located at the anterior ventricular wall, and are caused by total occlusion of the left anterior descending artery. Usually, the anterior and apical walls initially become akinetic; this can sometimes evolve into dyskinesia. Thrombus formation is a common finding, since the apical contractility is impaired. This tutorial illustrates the challenging technical aspects of a large thrombus removal, along with the geometric reconstruction of the left ventricular aneurysm and coronary bypass surgery.

RESUMO

Muscular pulmonary atresia with intact ventricular septum (PA/IVS) in neonates is traditionally managed by surgery. We describe hybrid approach to decompress the right ventricle (RV) and establish RV to pulmonary artery connection in a neonate avoiding cardiopulmonary bypass. A 21-gauge access needle was used to perforate the atretic pulmonary valve via periventricular approach followed by stent placement. This case is an example of how patients with congenital heart disease can be palliated in creative ways through thoughtful collaboration between surgical and interventional cardiology teams.
