RESUMO
BACKGROUND: Takotsubo syndrome (TS) is a reversible cause of heart failure; however, a minority of patients can develop serious complications, including cardiac rupture (CR). OBJECTIVES: Analyze case reports of CR related to TS, detailing patient characteristics to uncover risk factors and prognosis for this severe complication. METHODS: We conducted a systematic search of MEDLINE and Embase databases to identify case reports of patients with TS complicated by CR, from inception to October 2023. RESULTS: We included 44 subjects (40 females; 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity. An emotional trigger was present in 15 (34%) subjects and an apical ballooning pattern was observed in all cases (100%). ST-segment elevation was reported in 39 (93%) of 42 cases, with the anterior myocardial segments (37 [88%]) being the most compromised, followed by lateral (26 [62%]) and inferior (14 [33%]) segments. The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery was attempted in 16 (36%) cases, and 28 (64%) patients did not survive. CONCLUSIONS: CR related to TS is a rare complication associated with high mortality and affecting elderly females, specially from White/Caucasian or East Asian/Japanese descent, presenting with anterior or lateral ST-segment elevation, and an apical ballooning pattern. Although data is limited and additional prospective studies are needed, the awareness of this life-threatening complication is crucial to early identify high-risk patients. CONDENSED ABSTRACT: Cardiac rupture is a rare complication of Takotsubo syndrome. We conducted a systematic review of cases complicated by cardiac rupture, and we identified 44 subjects (40 females and 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity, all with an apical ballooning pattern (100%). The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery treatment was attempted in 16 (36%) cases, and 28 (64%) patients did not survive.

Left ventricular free wall rupture (LVFWR) is a rare but fatal complication of acute myocardial infarction (AMI). An 81-year-old female patient with several cardiovascular risk factors presented to the emergency department with symptoms of developing a chronic stomachache and cold sweat. An echocardiograph showed wall motion abnormalities from the lateral to posterior wall, as well as pericardial effusion containing clots of up to 17 mm in the posterior wall that indicated LVFWR after AMI. Although she was conscious after being brought to the initial care unit, she suddenly lost consciousness and fell into electromechanical dissociation (EMD). Endotracheal intubation was immediately initiated and her pericardial drainage and intra aortic balloon pump (IABP) placement, and hemodynamics recovered. Although she had 100% obstruction in the left circumflex artery (LCX) #12 on coronary angiography (CAG), she was discharged to the Intensive Care Unit (ICU) without percutaneous coronary intervention (PCI). Conservative treatment such as intubation, sedation, pericardiocentesis and strict blood pressure management as well as treatment by IABP long-term support led to the patient being uneventfully discharged after 60 days.

BACKGROUND: Left ventricular free wall rupture (LVFWR) is a rare complication after myocardial infarction and usually occurs 1 to 4 days after the infarct. Over the past decade, the overall incidence of LVFWR has decreased given the advancements in reperfusion therapies. However, during the COVID-19 pandemic, there has been a significant delay in hospital presentation of patients suffering myocardial infarctions, leading to a higher incidence of mechanical complications from myocardial infarctions such as LVFWR. CASE PRESENTATION: We present a case in which a patient suffered a LVFWR as a mechanical complication from myocardial infarction due to delay in seeking care over fear of contracting COVID-19 from the medical setting. The patient had been having chest pain for a few days but refused to seek medical care due to fear of contracting COVID-19 from within the medical setting. He eventually suffered a cardiac arrest at home from a massive inferior myocardial infarction and found to be in cardiac tamponade from a left ventricular perforation. He was emergently taken to the operating room to attempt to repair the rupture but he ultimately expired on the operating table. CONCLUSIONS: The occurrence of LVFWR has been on a more significant rise over the course of the COVID-19 pandemic as patients delay seeking care over fear of contracting COVID-19 from within the medical setting. Clinicians should consider mechanical complications of MI when patients present as an out-of-hospital cardiac arrest, particularly during the COVID-19 pandemic, as delay in seeking care is often the exacerbating factor.

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.

A 71-year-old man presented to us with recurrent chest pain, which led to cardiac catheterization. He was a strong candidate for redo coronary artery bypass grafting (CABG). CT was performed to confirm whether the heart was adherent to the sternum and chest wall. For safety reasons, cardiopulmonary bypass (CPB) was first performed via right femoral cannulation before sternotomy. After the spontaneous right ventricular (RV) rupture, HTK was used to arrest the heart. Heart repair materials were applied to repair the fissure of RV to avoid further tearing and bleeding. A compromise scheme was adopted when it was found to be difficult to identify and expose well the target artery, due to severe adhesion. This was done to avoid possible severe consequences of further dissection of the heart. Intraoperative transesophageal echocardiography (TEE) was used to evaluate the cardiac function, and intra-aortic balloon pump (IABP) support was applied in time. In consideration of the RV enlargement, which TEE revealed may have been caused by myocardial edema and cardiac insufficiency, modified ultrafiltration was performed, and a timely decision of open chest management (OCM) with delayed sternal closure (DSC) was made to maintain hemodynamic stability. The patient had no further complications and eventually recovered well, according to a 4-month follow up.

BACKGROUND: Ventricular rupture is rarely described in the literature outside the context of myocardial infarction, infection or neoplasm. It is associated with a high mortality rate due to late presentation and delayed surgical intervention, which involves sutureless or sutured techniques. Comprehensive literature review failed to identify any case of intra-operative right ventricular heart rupture followed by myocardial repair and a complete recovery after a prolonged intensive care unit (ICU) stay. CASE PRESENTATION: A 57-year-old previously healthy gentleman presented complaining of a new onset shortness of breath for 2 months. A large mediastinal mass was found on chest imaging and biopsy revealed a thymoma. Patient received a neoadjuvant Cisplatin/Doxorubicin/Cyclophosphamide (CAP) regimen chemotherapy then sternotomy and thymectomy en bloc with anterior pericardium. Post-thymectomy, the patient continued to be hypotensive in recovery despite aggressive fluid resuscitation. He was sent back to theatre, aggressive fluid resuscitation continued, surgical site exploration was done by reopening the sternum, and the bleeding source was identified and controlled, but intraoperative asystole developed. During internal cardiac massage, the right ventricle ruptured with a 3 cm defect which was successfully repaired using a pericardial patch without a bypass machine due to unavailability at our cancer center. The patient remained dependent on mechanical ventilation through tracheostomy for a total of 2 months due to bilateral phrenic nerve paralysis, was discharged from ICU to the surgical floor 66 days after the operation and weaned off ventilator support after 85 days, adequate respiratory and physical rehabilitation followed. Patient is doing very well now with excellent performance, and free of tumor recurrence 30 months after surgery. CONCLUSION: Right ventricular rupture is rarely described outside the context of myocardial infarction and valvular heart disease. Tumor proximity to the heart and neoadjuvant cardiotoxic chemotherapy are the proposed causes for precipitating the cardiac rupture in our case. Post-surgical patients who receive early physical rehabilitation and respiratory physiotherapy have improved survival and outcome.

On occasion in patients with stenotic congenitally bicuspid aortic valves (BAVs), the quantity of calcium in one of the cusps is considerably greater than in the other cusp. We examined operatively excised stenotic congenitally BAVs in 630 patients having isolated aortic valve replacement (No other cardiac valve was replaced, and none had had infective endocarditis.) Of the 630 valves, 3 contained a perforation in the mildly calcified cusp due to a large calcific "spur" extending across the orifice from a heavily calcified cusp. In conclusion, heavy calcific deposits in 1 of 2 BAVs may extend across the orifice causing a perforation in the noncalcified portion of the opposing cusp.

Interventricular septal hematoma following congenital cardiac surgery is an uncommon entity. Literature search reveals few cases of interventricular septal hematoma complicating pediatric cardiac surgery. We report a case of interventricular septal hematoma following patch closure of ventricular septal defect, with associated myocardial necrosis and myocardial rupture.

A 56-year-old man who underwent routine aortic valve replacement (AVR) for aortic insufficiency suffered a presumed embolic event to a small vessel supplying the posteromedial papillary muscle. This led to papillary muscle rupture, and severe, acute mitral regurgitation requiring emergent mitral valve replacement 6 days postoperatively. Small-vessel coronary embolization outside the setting of infection/endocarditis leading to infarction and papillary muscle rupture following elective AVR has not been previously described in the literature.

Although aortic valve (AV) replacement is a curative procedure for severe aortic stenosis, prosthetic heart valves have many disadvantages and cause serious complications. A new promising surgical procedure-aortic valve neocuspidization (AVNeo)-has recently been developed; it is an original method of AV reconstruction with autologous pericardium. It has been reported to yield excellent medium-term results with respect to durability and complications. Herein, we encountered a first case of AV leaflet tear and perforations 27 months after AVNeo using autologous pericardium. AV leaflet tear or perforation is well recognized as a long-term serious complication of pericardial xenografts. Interestingly, however, AVNeo caused early structural valve deterioration in the current case. In the present case, an eccentric aortic regurgitation jet observed on colour flow imaging led us to reach the correct diagnosis. Finally, the patient showed complete recovery with redo AV replacement. This case highlights the importance of understanding the potential pitfalls of this new surgical technique and that of colour Doppler echocardiography in reaching a definite diagnosis.

OBJECTIVE: Emergency surgical treatment is required for idiopathic acute mitral regurgitation due to chordae rupture in infants. Nevertheless, mitral valve repair for such a patient population still remains challenging. We report our experience with mitral valve repair for idiopathic acute mitral regurgitation due to chordae rupture in infants. METHODS: From 2005 to 2017, six infants (four boys) were diagnosed with acute mitral regurgitation due to chordae rupture and underwent mitral valve repair. The median age, mean body weight, and median follow-up period were 5.5 months (range: 4-9 months), 6.8 kg (range: 5.5-8.0 kg), and 6.4 years (range: 6 months to 10 years), respectively. RESULTS: In all cases, surgical intervention was performed within 24 hours of admission. Artificial chordae reconstruction and paracommissural edge-to-edge repair were utilized in three and four cases, respectively, while Kay's annuloplasty was performed in all cases. Mean cardiopulmonary bypass time and aortic cross-clamp time were 117 minutes (range: 70-143 minutes) and 73 minutes (range: 35-108 minutes), respectively. No early or late deaths and reoperations had occurred during the follow-up period. Moreover, postoperative mitral regurgitation was significantly reduced, while no chronologic progression of mitral regurgitation was observed. CONCLUSIONS: The combination of various techniques, such as artificial chordae reconstruction, paracomissural edge-to-edge repair, and Kay's annuloplasty, can be a promising surgical option for idiopathic acute mitral regurgitation due to chordae rupture in infants.

Papillary muscle rupture is a rare complication after myocardial infarction and almost all cases occur in the mitral valve papillary muscle. Tricuspid regurgitation development after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare. In this video tutorial we present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous stenting of the right coronary artery. We performed tricuspid valve repair with reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve. There are no previous case reports of this surgical repair technique.

A 21-year-old man with Wolff-Parkinson-White syndrome presented to the authors' hospital with ventricular fibrillation. Coronary angiography failed to demonstrate coronary stenosis, but temporary mechanical circulatory support resolved the ventricular fibrillation and the patient was extubated eight days later. On the next day, however, he had to be re-intubated with symptoms of congestive heart failure. Echocardiography revealed new severe mitral regurgitation and a mobile mass, while emergency surgery revealed a posteromedial papillary muscle rupture (PMR). The mitral regurgitation was repaired with ruptured papillary muscle relocation, artificial chordae implantation, and ring annuloplasty. Postoperative examinations suggested that an arrhythmia-induced coronary circulation hypoperfusion and septic embolization had caused the PMR.

A 69-year-old man was admitted to our hospital for dyspnea and fever. Echocardiography showed a mobile mass on the anterolateral papillary muscle and severe mitral regurgitation. Coronary artery angiography showed no stenotic lesion. Infective endocarditis or cardiac tumor was suspected, and a mitral valve operation was performed. Intraoperative observation revealed a partially ruptured anterolateral papillary muscle and no evidence of infection or tumor. Pathologic examination of the resected papillary muscle showed atherosclerotic changes in small arteries and infarcted areas in different postinfarct time phases along the ruptured edge. It could be speculated that microvascular stenosis caused the repeated localized subendocardial infarction over time.

AIM: We aimed to illustrate the physiopathology of anterior mitral leaflet perforation after TAVI in patients suffering from infective endocarditis (IE). METHODS AND RESULTS: The first known case of balloon-expandable transapical case from our series suffering from this complication was reported. In addition, a systematic electronic search of all published cases reporting both entities was performed. Five transfemoral cases have been published to the date, all males with mean age of 79.2 year (range: 66-88). Four were treated with self-expandable prostheses (deeply implanted in the outflow tract). There was moderate residual aortic regurgitation in four. Fever and positive blood cultures for typical micoorganisms were present at certain time point in all cases between the first week and up to 11 months (early IE). Three cases underwent cardiac surgery with adequate outcomes and two others died during hospitalization. Medical management in the case from our series allowed patient's survival at 1-year follow up. CONCLUSIONS: Early suspicion of IE whenever anterior mitral perforation is found after TAVI can be life-saving. The hypothetical higher risk of this complication due to higher rate of aortic regurgitation has to be prevented through adequate prosthesis depth and careful sterile surgical technique. © 2016 Wiley Periodicals, Inc.

A patient with symptomatic typical atrial flutter (AFL) underwent right atrial isthmus ablation with an 8-mm catheter. Eight months later, his typical AFL recurred. Ten months later, he underwent a repeat right atrial isthmus ablation with an irrigated tip catheter and an 8-mm tip catheter. Six weeks after his second procedure, while performing intense sprint intervals on a treadmill, he developed an abrupt onset of chest pain, hypotension, and cardiac tamponade. He underwent emergency surgery to repair an atriocaval rupture and has done well since. Our report suggests that an association of multiple radiofrequency ablations with increased risk for delayed atriocaval rupture occurring 1 to 3 months after ablation. In conclusion, although patients generally were advised to limit exercise for 1 to 2 weeks after AFL ablation procedures in the past, it may be prudent to avoid intense exercise for at least 3 months after procedure.

Left ventricular free wall rupture usually leads to acute hemopericardium and sudden cardiac death resulting in cardiac tamponade. Rarely, only a few patients with subacute free wall rupture such as oozing-type ventricular rupture or left ventricular false aneurysm may permit time for pericardiocentesis and surgery. We report a 63-year-old man with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention about 12 hours from the onset, and cardiac tamponade occurred on the second day. An intra-aortic balloon pump (IABP) was immediately inserted for hemodynamic support. After 100 mL of pericardial fresh blood was drained from the percardial cavity, his hemodynamic collapse was promptly improved with IABP support. In the following 24 hours, about 600 mL of hemorrhagic pericardial fluid was drained. The most likely diagnosis was concerning for oozing-type ventricular rupture, and a conservative approach was decided. The patient survived to the acute phase under IABP support and was discharged with complete recovery.
