Abstract Left ventricle (LV) to right atrial (RA) shunt is a rare type of ventricular septal defect. Acquired LV-RA shunt is rare and may occur as complication of cardiac surgery, endocarditis, thoracic trauma or myocardial infarction. Infective endocarditis is the second most important cause of this type of shunt. Case presentation A 44 year old female patient presented to our hospital complaining of progressive exertional dyspnea and palpitations for 6 months, and high grade fever for 2 weeks. The patient had history of mitral valve replacement with mechanical prosthesis 16 years ago. The patient had no history of recent invasive procedures or dental interventions. General examination revealed an irregular pulse at rate of 100 beats per minute (bpm), blood pressure of 100/60 mmHg, temperature of 38.5 ͦ C and congested neck veins. Cardiac examination revealed an audible prosthetic mitral click with a harsh pansystolic murmur heard on the apex and left sternal border, and an accentuated P2 over the pulmonary area. Her resting electrocardiogram (ECG) showed atrial fibrillation with ventricular response of 110 bpm. Her laboratory investigations revealed normochromic normocytic anemia with Hemoglobin level of 8 g/dl (13-16), and leucocytosis with white blood cell count of 16.24 103 cell/ ul (4.00-11.00); as well as elevated C-reactive protein (CRP) level of 73 (0-3). Her international normalized ratio (INR) was 3 (1-1.3) on warfarin 5 mg. Transthoracic echocardiography (TTE) revealed a dehiscent prosthetic mitral valve with severe paravalvular regurgitation, severe tricuspid valve regurgitation and pulmonary hypertension with predicted resting pulmonary artery systolic pressure of 60 mmHg. It also showed an abnormal jet passing from the LV into the RA above the tricuspid valve during systole, both right and left ventricular systolic functions were preserved. Subsequent 2D/3D transoesophageal echocardiography (TEE) confirmed the TTE findings with detection of LV-RA fistula with significant left to right shunt; it also visualized multiple vegetations attached to the mitral annulus at the site of the valve dehiscence. The patient was diagnosed with prosthetic mitral valve infective endocarditis, empirical antibiotics were started and the patient was referred for another center for urgent surgery. Redo mitral valve replacement, tricuspid valve repair and closure of the defect were done; the patient developed complete heart block postoperatively and permanent pacemaker was inserted. Conclusion Infective endocarditis remains a major health problem with high mortality and severe complications. It is important to keep high index of suspicion in high risk patients for infective endocarditis as delayed diagnosis increases the risk of serious complications and mortality, and makes surgical intervention, if indicated, more demanding with increased incidence of perioperative complications.

Abstract We report a 62-year-old man with a past medical history of dyslipidemia, paranoid schizophrenia and permanent atrial fibrillation. A ATTE performed at his district hospital revealed rheumatic mitral valve disease with double lesion: severe regurgitation and mild stenosis, plus moderate tricuspid regurgitation and a mean PAP of 32mm Hg. Cardiac catheterization showed no abnormalities of the coronary arteries. He was transferred to our hospital and scheduled for mitral valve replacement and tricuspid ring valvuloplasty. Preoperative transesophageal echocardiography showed an abnormal subvalvular mitral apparatus, with false tendons and multiple papillary muscles, resembling a hammock mitral valve. Most cordae tendinae arose from a single dominant papillary muscle at a posterior medial region, which provoke severe mitral regurgitation due to coaptation defect and mild subvalvular mitral stenosis. It could also be appreciated hypertrabeculation in the lateral medial, basal and apical segments. This suggested no-compaction cardiomyopathy associated with hammock mitral valve. Left ventricular systolic function was preserved. No evidence of rheumatic mitral valve disease was found in transesophageal echocardiographic study performed at our hospital. On the 30th April 2019 he underwent mechanic mitral valve replacement (Bicarbon 29mm) and tricuspid ring valvuloplasty (Edwards Physio 32mm) surgery. Once the patient was weaned from cardiopulmonary bypass, severe left ventricle systolic dysfunction ensued, predominantly localized in the anterior, inferior septal, inferior lateral basal and medial segments. Apical segments had preserved mobility An adrenalin infusion prior weaning from CBP was initiated. Preserved mobility of the mitral prosthesis discs was observed. The patient developed cardiogenic shock in spite of high doses of dobutamin and adrenaline infused. IACB was implanted with 1:1 assistance. The patient was transfered to the hemodynamic room in order to rule out coronary complications. Cardiac catheterization showed no significant angiographic lesions. During the first postoperative hours, the patient was stabilized allowing progressive lowering of the drugs (adrenaline, dobutamine). TTE showed normally functioning prosthetic mitral valve and preserved left ventricle systolic function. An MRI was performed demostrating no-compaction cardiomyopathy Conclusion This case report describes a rare presentation of simultaneous ocurrence of hammock mitral valve and no-compaction cardiomyopathy. Perioperative left ventricle dysfunction in no-compaction cardiomyopathy is related to subendocardial ischemia caused during extracorporeal circulation in the multiple prominent ventricular trabeculations with deep intertrabecular recesses corresponding to non-compacted myocardium .This must be taken account in those patients with no-compaction cardiomyopathy scheduled for cardiac surgery in order to take preventive measures.

Background: Dilated left ventricle occurs in chronic aortic and mitral regurgitations. We describe the early outcome of mitral and aortic valve replacement for patients with severely dilated left ventricle in different surgical interventions. Methods: From March 2014 to December 2018, 620 patients with left ventricular end-diastolic diameter (LVEDD) of ≥ 70 mm underwent valve replacement procedures in 8 cardiac surgery centers in Egypt. One hundred ninety four cases (31.3%) underwent aortic valve replacement, 173 cases (27.9%) underwent mitral valve replacement, 123 cases (19.9%) underwent double valve replacement, 59 cases (9.5%) underwent double valve replacement with either tricuspid valve repair or replacement, 33 cases (5.3%) underwent mitral valve replacement with either tricuspid valve repair or replacement, 20 cases (3.2%) underwent mitral valve replacement with CABG, 10 cases (1.6%) underwent aortic valve replacement with CABG, while 8 cases (1.3%) underwent aortic valve replacement with ascending aortic aneurysm repair. Results: Four patients (0.6%) developed new postoperative renal failure, which required dialysis. Twenty-nine patients (4.7%) required reoperation for bleeding. One patient (0.2 %) developed sternal dehiscence. Five patients (0.8%) postoperatively developed stroke. Twenty-five patients (4%) died, and the main causes of death were low cardiac output and sepsis with eventual multi-organ failure. Conclusion: Valve replacement in patients with hugely dilated left ventricle are safe operations with satisfactory outcomes even if combined with other procedures, especially with proper preoperative preparation, intraoperative preservation of posterior mitral leaflet, and meticulous postoperative follow up in the surgical ICU.

Abstract Background Left ventricular pseudoaneurysm due to early left ventricle rupture is a serious complication after cardiac surgery. Urgent surgery is recommended in most cases with a high mortality rate. Conservative treatment of a left ventricular pseudoaneurysm due to early left ventricle rupture is very rare. Case presentation We present a 61-year-old woman with left ventricular pseudoaneurysm after mitral valve replacement due to early left ventricle rupture. This patient was treated in a conservative approach. This patient had an uneventful recovery. She was in good condition and remained asymptomatic 3.5 years after mitral valve surgery. Conclusion This case suggests that medical treatment left ventricular pseudoaneurysm patients has a limited but acceptable role in selected and unusual circumstances.
