Abstract

A 57-year-old male patient who is a known case of hypertension well controlled on ramipril presented with a history of shortness of breath and palpitation of 3 months duration. The symptoms were insidious in onset; however, it progressed rapidly over the period of 3 months, wherein at present the patient feels breathless in performing normal daily activities of living making him New York Heart Association class III patient. Palpitations are regular in nature and present throughout the time and are exacerbated on performing even light activities within his house. There was associated swelling of bilateral lower limbs that usually improved after a night's rest; however, it was not completely resolved. The individual did not give any history of chest pain, presyncope, syncope, or any other symptoms that pointed toward a cardiac condition.

Introduction

The essentiality of having a transesophageal echocardiography (TEE) cover the Bentall surgery is often overlooked.

Case History

A 57-year-old male patient who is a known case of hypertension well controlled on ramipril presented with a history of shortness of breath and palpitation of 3 months duration. The symptoms were insidious in onset; however, it progressed rapidly over the period of 3 months, wherein at present the patient feels breathless in performing normal daily activities of living making him New York Heart Association class III patient. Palpitations are regular in nature and present throughout the time and are exacerbated on performing even light activities within his house. There was associated swelling of bilateral lower limbs that usually improved after a night's rest; however, it was not completely resolved. The individual did not give any history of chest pain, presyncope, syncope, or any other symptoms that pointed toward a cardiac condition.

Consultation in the cardiology clinic at our institute at All India Institute of Medical Sciences, CTC, New Delhi, was sought. General physical examination revealed a bounding radial pulse with a normal rate and rhythm. The patient had high systolic blood pressure reading (150–160 mm Hg) and low diastolic blood pressure reading (40–50 mm Hg) with a wide pulse pressure. There was bilateral pedal edema till ankle that was pitting in nature. On systemic examination, the cardiac apex was felt in a downward and outward location suggestive of cardiomegaly. On auscultation of the chest, an early diastolic murmur was heard prominently in the aortic area. Routine investigations that included electrocardiogram (ECG), chest X-ray (CXR), TTE, computed tomography (CT) angiography, and blood workup were done.

ECG was normal with a sinus rhythm of around 75 bpm and normal axis. CXR showed a CT ratio >0.6, with widened mediastinum and the cardiac apex displaced down and left.

Transthoracic ECHO Findings

Two-dimensional TTE revealed a bicuspid aortic valve with severe aortic regurgitation, with increased dimensions of aortic sinus (49 mm), sinotubular junction (STJ) (68 mm), ascending aorta (96 mm). and a reduced ejection fraction (35–40%). CT angiography confirmed the findings with the following measurements: annulus (33 × 26 mm), sinus (49 × 49 × 49mm), effacement of STJ, ascending aorta (103 mm). Coronaries were normal and showed no obstruction to flow.

Blood investigations were within normal range except for deranged serum urea and creatinine (58/1.6 mg/dL) preoperatively. Intraoperative TEE probe was inserted, as is a mandate in all cardiac surgery patients, in our center. The images found are shown from Figs. 1 2 3 4 5 to 6.

Discussion

The Bentall procedure entails the surgical implantation of a composite graft to replace the aortic valve and portion of the ascending aorta, with the reimplantation of the coronary arteries into the graft. TEE has an invaluable role in the prognosis, especially in detecting the coronary blood flow, post-surgery (Fig. 7).

Early postoperative TEE may show a periaortic hematoma with markers of inflammation such as fever, which the patient may develop in the intensive care unit. A periaortic abscess leading to fever must be distinguished from a periaortic hematoma both due to surgical manipulations of the graft or due to graft leaking; TEE is the gold standard for any endocarditis detection, with or without any abscess. A TTE can postoperatively detect paraprosthetic regurgitation just as well as a TEE. Strong prosthetic reflectors with anterior washing jets (Figs. 7 and 8) may actually be color Doppler artifacts that seem to move through the solid structures of the prosthetic root. These are better visualized on TTE than with TEE.1, 2, 3 TEE estimates the aortic regurgitation volume, pre- and post-Bentall procedure, much better than the TTE does also; TEE is better for paraprosthetic regurgitation in a prosthetic aortic valve and also when aortic regurgitation is eccentric.4 There may be high transprosthetic gradients, post-Bentall procedure, or some thrombosis or asymptomatic aortic prosthetic dysfunction, but this is less in aortic valve than in a mitral prosthetic valve (Fig. 8). Our patient has high aortic gradients as it was a case of severe aortic stenosis as well as severe aortic regurgitation. With passage of time, a surveillance TEE done will show the left ventricular remodeling with better aortic gradients across the left ventricular outflow tract.

Postoperative gradient measurement across the aortic valve remains high but shows no aortic regurgitation jets. The prosthetic shadow is showing anterior wash. Strong prosthetic graft reflectors are seen.

Conclusion

Performing TEE during the Bentall surgery, preoperatively, intraoperatively, and postoperatively, is essential and recommended for all patients for optimal outcomes. TEE should preferably be continued with TTE in the early postoperative period to rule out high gradients for periaortic hematomas and/or abscesses. Performing TEE in all stages of Bentall procedure is a hope, not a hype.
